- Dotnet >> Dataset alternative to stored proc row resultsUsing the reader object I'm not having a problem retrieving stored
procedure return values, but I'm having trouble getting at the actual
data coming back in the row results. My first impulse would be to fill
a dataset, but I'd prefer to return the results in a more generic
fashion, hopefully via the reader. Again, these are row results coming
back from a proc, so there won't be any named variables to work with.
Any suggestions?
Thanks in advance,

- Visual C#.Net >> COM interoperatability using PInvoke (SEH Exception)Hi All,
I am trying to call COM Component in .NET using PInvoke.
In the following scenario, ( I am getting an exception called SEH -
External component has thrown an exception)
UnManaged Code
---------------
virtual HRESULT IDispatch::GetIDSOfNames(const IID & riid, LPWSTR *
rgizNames, UINT CNames, LCID lcid, DISPID *rgDispID)
Managed Code (I have rewritten)
------------
int GetIDsOfNames ([In] System.Guid guid, ref System.String[]
rgNames,[In] System.UInt32 cNames, [In] System.UInt32 lcid,
[Out] out long[] dispID);
Public Test()
{
AXIDispatch pIScriptDispatch;
String[] wszScriptFunctions = new String[1];
wszScriptFunctions[0] = "entryMethod";
long[] dispIDFunctions = new long[1];
pIScriptHost.GetScriptDispatch (out pIScriptDispatch);
IntPtr p = Marshal.GetIDispatchForObject(pIScriptHost);
IntPtr ppv;
Marshal.QueryInterface(p,ref diug,out ppv);
pIScriptDispatch = (AXUtil.AXIDispatch)Marshal.GetObjectForIUnknown(ppv);
try
{
pIScriptDispatch.GetIDsOfNames (guid,ref wszScriptFunctions, 1,
1033, out dispIDFunctions);
}
catch (Exception ex)
{
Console.WriteLine (ex.ToString ());
}
}
If I execute Test() I will be getting the following Exception for
Invoking "GetIDsOfNames(....)"
System.Runtime.InteropServices.SEHException: External component has
thrown an exception.
What could be the reason to get this kind exeception, I don't know
what to do in order to handle it error. Could anyone
kindly help me to solve ? I will greatly appreciate.
Thanks & Regards

- ADO >> How to resolve "General Network Error"?I'm getting the following message trying to update a SQL Server table:
"General network error. Check your network documentation."
I'm using stored procedures via a SQL data connection from within a .Net
windows application. The application producing the error, reads a table from
the server, then proforms a series of updates, deletions and insertions
locally to a DataSet. After all processing is completed, the data is written
back to the server using the Update(dataset, "table_name") method on the
DataAdapter. The Update method is called 3 times, once for all updated rows,
once for all inserted rows and once for all deleted rows.
Currently, I read and update 3 tables in seperate datasets. 2 tables work
and the 3rd does not. How can I get resolved this issue?

- Dotnet >> Localized Exception Messages in WinFormsSystem exception messages in VS2005 are given in the local language.
Sometimes it is nice, but often it is quite inconvenient - try looking up
MSDN or Google with a localized message!
So, after having received a rather obtuse message concerning a P/Invoke
error, I spent some time getting rid of this unwanted feature, and I wish to
share with you the results.
First, my solution: In the Load event of the main form, add:
Thread.CurrentThread.CurrentUICulture = new
System.Globalization.CultureInfo ("en-US");
Now, the explanation:
Visual Studio Debugger, How to: Find Out More About an Exception with the
Exception Assistant says quite clearly:
"Message: Message associated with the exception. This is displayed in the
language specified by the CurrentUICulture property of the thread that
throws the exception."
So it is a feature, albeit not well considered.
Where does CurrentUICulture come from?
The help at NET Framework Class Library, Thread.CurrentUICulture Property,
advises:
Application.Run(new UICulture());
But this is wrong, Application.Run does not take a culture parameter, and
the Application.CurrentCulture property does not affect the behavior of the
exception assistant - CurrentCulture and CurrentUICulture are not the same
thing! CurrentUICulture is a property of the thread, and is not affected by
either of the application CurrentCulture or the assembly
NeutralResourcesLanguage attribute. It is the language specified in the
control panel regional and language options.
The assembly Culture attribute may not be used: "Information on the culture
or language the assembly supports. This information should be used only to
designate an assembly as a satellite assembly containing culture- or
language-specific information. (An assembly with culture information is
automatically assumed to be a satellite assembly.)"
So we are left with dynamically modifying the thread CurrentUICulture.
In development I can make it depend on #if DEBUG. But what if a user in
another country gets a system exception using my software? I will get the
error message in his language and what could I do with it?
See http://msmvps.com/blogs/calinoiu/archive/2006/06/30/103426.aspx

- Winforms >> ListView.tag lost objectHi,
I have a Form with two ListViews; The ListViews are diplayed on the
Design surface, but I progmatically adding the items to each ListView.
When adding the items to the list view I am iterating through and
setting the following:
...
With myListViewItem
.Text = drArticles("Title").ToString
.ToolTipText = drArticles("Summary").tostring
.Tag = CType(drArticles("ID"),Guid)
End With
myListView.Items.Add
...
This works fine and the items are displayed.
The problem arises when I respond to a SelectedIndexChanged event I can
retrieve the .ToolTipText and .Text values from then
SelectedListViewItemCollection but the .tag property is always empty (it
knows the object type is GUID but does not have the value. I know the
value is being set as I can set the ToolTipText to same ID as the TAG
and it is stored correctly.
Any ideas?
Many thanks in advance

- Dotnet >> Bizar problem with a form (different instances act like one!)Hi all,
I have got a really weird problem:
- A normal VB.net forms application
- One MDI child form with a bunch of controls (tabs, radiobuttons, combo's,
etc.)
- The form is called from several procedures as kind of a dialog
- To my knowledge we haven't done anything in the disigner / code which can
be described as unusual
When de form is called multiple time they seem te listen to each others
events! So when I change a combo, the combobox will change on all forms ?!
All instances are created through a new / contructor and to my knowledge no
variables / controls are declared as static.
Does anyone have ever seen this or made this kind of functionality on
purpose?
I better hope it isn't a little switch in de IDE we turned on by accident.
Hope you can help,
Best regards,

- Dotnet >> Rule ManagementHello all,
If you were to order a a Z-28, you can get a bunch of options on it and in
odd configurations. However, if you were to select the option for the 350
cu in engine, you cannot have the T-Tops option as well. And, if you choose
red exterior, you must have leather interior.
My point and question is this. Is there a design pattern out there or a
best practice for implementing those types of rules? I think that the way I
am going about it, my business logic knows way too much about my data and,
at times depends on the presence of some data in the database. I would like
to get away from that, allow the "look-up" list manager (the person entering
options into the database) to specify the rules that will be enforced at
point of sale.
Thanks in advance gang.

- Visual C#.Net >> Adding Items to ComboboxI am using a C# combobox control. There are too many items to add right from
the start, I want to add 20 or so, then when the user cursors down to the
last one and cursors down again, I will add the next 20 so that they can
continue. Is there an event for when the user has reached the end of the list?
The only other was I can think of to handle it would be to capture each time
they pressed the up or down arrow, then see if the value changed, and if not,
add items. Is there not a better way than that? Thanks.

- Dotnet >> .NET 1.1 (and possibly 1.0 also) Threads leaking "Event" handles. [BUG??]Hi,
Threads in the .NET Framework 1.1 (and possibly in 1.0 also) leak "Event"
handles, by Event handles I mean Win32 Event handles which can be monitored
using the ProcessExplorer from www.sysinternals.com, or even simply look at
the Handle count in the good old windows TaskManager.
To demonstrate the problem, all I did was created a basic Win Forms
application and with Main implemented as:
[STAThread]
static void Main()
{
Application.Run(new Form1());
}
and Form's constructor as
public Form1()
{
while(true)
{
Thread thread = new Thread( new ThreadStart( ThreadProc) );
thread.Start();
Thread.Sleep(1000);
GC.Collect();
}
}
and the ThreadProc is implemented simply as
protected void ThreadProc()
{
Thread.Sleep(100);
return;
}
Now you let it run for a while and monitor the handle count using the
ProcessExplorer or TaskManager to can see that the thread count becomes more
or less constant after a bit (which means that an equilibrium is reached in
which the threads being created and thread which die is same), you will note
that the Handle count keeps on increasing. I have monitored upto 10000
handles after which I killed the application.
Now, this seems like a bug. Has someone got any explaination for this and
possibly a workaround. BTW, I also tried changing the attribute on Main from
STAThread to MTAThread with no change in behavior.
Any help/suggestions would be appreciated.
thanks,
Rohit

Microsoft Project >> Overallocation issue
Hi All,
I have also another overallocation problem and I got crazy with it last
2 months. It became quite critical for me and still can't solve it.
I've simplified it (8 basic tasks over 8 phase), 4 resources, single
resource assignments, work entered. Read all articles, watched training
movies, searched online helps and digged news groups.
I desperately need a help for that. I will be happy if you can help me
or forward me to somewhere.
Best Regards

Microsoft Project >> Overallocation issue
Hi,
You can find file at : www.siskon-tr.com/project.zip
1=2E There is no deadline for the tasks
2=2E All tasks are ASAP
3=2E I've tried all but currently they are at Fixed Units.
I am expecting it to extend the project end time to solve
overallocations. But even I use resource leveling, it gives always
error message instead of extending it.
This looks weird to me.
I have to submit my project plan and I'll be happy if you can help me.

Microsoft Project >> Overallocation issue
Hi Anvi,
Well, the project I opened had several tasks constrained that were not As
Soon As Possible. As soon as I changed them all to that constraint, the
project levelled with no overallocations with the selection Hour by Hour and
Priority,Standard settings.
FAQs, companion products and other useful Project information can be seen at
this web address: http://project.mvps.org/faqs.htm
Hope this helps - please let us know how you get on :)

- Net Framework >> Nullable boolean true on webservice response comes across as nullHello all,
I'm working on a web app that we converted over to asp 2.0 recently and
here's the issue I ran into:
We use a java webservice to retrieve data and display this data to the user.
This was working in 1.1 and nothing changed around this particular webservice
call on either side after the switch to 2.0. The webservice response is an
array of value objects and the value object contains a boolean. I intercepted
the response with Fiddler and verified that the boolean was set to either
true or false on all the vo's in the array. But after the response object was
created and I could look at it in the code while debugging, the (nullable)
boolean field in every vo in the array was null.
To fix this temporarily, I had the webservice provider change the boolean
field to a 'NullableBoolean' class that contained a boolean value - this way,
the correct value came across and I could work with it.
I'm not sure if this is helpful, but there's one more detail I noticed -
The xml doc I intercepted with Fiddler looks something like this
('processed' is the boolean variable):
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"...>
<env:Body env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
...
<responseVos...>
...
<ResponseVo ...>
...
<processed href="#ID_4"/>
...
</ResponseVo>
...
</responseVos...>
...
<xsd:boolean xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:type="xsd:boolean" id="ID_4">true</xsd:boolean>
...
</env:Body>
</env:Envelope>
This is working for now but I think I shouldn't have to have my webservice
provider fix my problem, right? Any help in solving this problem would be
greatly appreciated.

- Visual C#.Net >> CollectionBase in Net1.1 and Collection in Net 2.0Hi,
I have some collections that inherit from CollectionBase in Net 1.1

- Dotnet >> Composite UI application Block - Thread Safe?Does anyone have any input on setting up my CAB application so that the
application is thread safe, and cached appropiately? I read that this
can be managed through Services, and dynamic injection. On the
contrary, I was told that this can be handled using Enterprise Library
cached application block. Last, but not least, i read you can implement
this at the class level, creating immutable classes, and caching them
accordingly. Any suggestions would be greatly appreciated?

- Visual C#.Net >> BinaryReader munges dataI'm about to rip out what little hair I have left; I have a class that
uses a BinaryReader, and the data is getting munged. A subset of the
code follows; I've removed the parts that aren't relevant.
What's really strange is that it reads the file just fine until the
272nd call to the Read method of the class, at which point it begins
munging the data.
Any thoughts would be greatly appreciated; I've tried reading by byte,
as well as reading blocks, and it makes no difference.

- ADO >> MSDE and TransactionScopeI have a C# application that applys a set of scripts to a database to create
the structures. When each script is applied, I encapsulate the call within a
TransactionScope. Everything works fine on SQL Server 2000 sp4, 2005 sp1,
and Express 2005 sp1 databases.
On MSDE2000 SP4, I consistently get transaction timeouts on my scripts.
However, it is never the same script. These are the same scripts I use on
other database, so I am confident that the scripts themselves are fine.
Everything is running locally on one machine. MSDTC is running. I've tried
restarting the services, restarting the machines, and connection pooling
seems to be ok, and I'm running out of ideas to check.
Has anyone had a similar experience or can recommend something to check?

- Net Framework >> EMBEDDING images - System.Web.MailHi, I hope there is someone reading this that has the answer, Please Help!
I have the need to send a html email via asp.net. its easy enough to send
an html email and add attachments.
My question is, how to you set the Content-Location of each attachment in
the mail headers so that the images are embedded in the html email rather
than attached?
This is my code:
private void Page_Load(object sender, System.EventArgs e)
{
MailMessage objEmail = new MailMessage();
objEmail.From = aspnet@domain.com;
objEmail.Subject = "news flash ";
string body = "<html>.....
{some html code with images as <img src=\"news_r1_c1.jpg\"> ... etc
</html>";
objEmail.Body = body;
objEmail.Priority = MailPriority.Normal;
objEmail.BodyFormat = MailFormat.Html;
MailAttachment i1 = new
MailAttachment(Server.MapPath("images/news_r1_c1.jpg"));
MailAttachment i2 = new
MailAttachment(Server.MapPath("images/news_r1_c3.gif"));
MailAttachment i3 = new
MailAttachment(Server.MapPath("images/spacer.gif"));
MailAttachment i4 = new
MailAttachment(Server.MapPath("images/news_r4_c1.jpg"));
MailAttachment picture = new
MailAttachment(Server.MapPath("images/default.jpg"));
objEmail.Attachments.Add(i1);
objEmail.Attachments.Add(i2);
objEmail.Attachments.Add(i3);
objEmail.Attachments.Add(i4);
objEmail.Attachments.Add(picture);
string sendto = Request.Form["recipients"];
string[] recipients= sendto.Split(',',';');
foreach(string recipient in recipients)
{
objEmail.To = recipient.Trim();
SmtpMail.SmtpServer = "smtp.server,com";
try
{
SmtpMail.Send(objEmail);
}
catch (Exception exc)
{
Response.Write("Send failure: " + exc.ToString());
}
}
}
as said, html email is coming through fine, images are in email as
Attachments, but DON'T display inline with the page (even though the
attachments are named correctly corresponding to the image names in the HTML
(<img src="imagename.jpg"> where imagename.jpg is attached).
I have sent HTML emails with embedded images in Classic ASP using CDONTS
quite easily, i need to do the same in .NET!
[FYI code to attach in ASP is:
objMail.AttachURL server.MapPath("images/imagename.jpg"), "imagename.jpg"
]
a quick look at the message source shows this at the top of the part that
holds the binary information about the image, in the email source:
for the ASP version (that works) :
------=_NextPart_000_000A_01C3EF89.62C8CA30
Content-Type: image/jpeg
Content-Transfer-Encoding: base64
Content-Disposition: attachment
Content-Location: news_r1_c1.jpg
in the ASP.NET version (doesn't show images inline)
------=_NextPart_000_005D_01C3F184.ECF34990
Content-Type: image/jpeg;
name="news_r1_c1.jpg"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="news_r1_c1.jpg"
notice how there is no Content-Location with the image name in the .NET
version, this is obviously needed to tell the mail client where the attached
images should be displayed in the HTML email.
Now does anyone know how to set this in the .NET mail object??
any help/leads in the right direction are appreciated.
The doesn't seem to be anywhere to set this property in the MailAttachment,
or MailAttachments.Add methods, and i couldn't find any answers in the docs
Please help
Thanks
Tim

- Visual C#.Net >> Programmatically disabling Windows Control EventsHi
I wanted to programmatically disable events like SelectedIndexChanged without
using a boolean flag, which indeed I find a quick and dirty solution. So, I
found a
piece of code that do this more elegant:
* How to disable event in C#?
Link: http://tinyurl.com/alsge
Group: microsoft.public.dotnet.framework.compactframework
But I saw it is limited to ComboBoxes and to the SelectedIndexChanged Event
and
I want to generalize it to an object of type control and to every possible
event. To
give you an idea, I will post some of my ugly code:
public static EventHandler DisableSelectedIndexChanged(Control control)
{
FieldInfo fieldInfo;
object fieldObject;
EventHandler handler = null;
fieldInfo = control.GetType().GetField("SelectedIndexChanged",
BindingFlags.Instance | BindingFlags.NonPublic);
if (fieldInfo != null)
{
fieldObject = fieldInfo.GetValue(control);
if (fieldObject is EventHandler)
{
handler = (EventHandler)fieldObject;
//This is the part I want to avoid
if (control is ComboBox)
((ComboBox)control).SelectedIndexChanged -= handler;
else if (control is ListBox)
((ListBox)control).SelectedIndexChanged -= handler;
else if (control is ListView)
((ListView)control).SelectedIndexChanged -= handler;
else if (control is TabControl)
((TabControl)control).SelectedIndexChanged -= handler;
}
}
return handler;
}
Is it possible to avoid the casting and get a pointer to the
SelectedIndexChanged
property, then apply the -= operation over it? How? As I could understand,
FieldInfo.GetValue(control) only returns the handler, but not the
SelectedIndexChanged property.
Thanks in advanced,
Josef
