- Visual C#.Net >> Unable to write data to the transport connection: An established connectionHello,
I'm trying to upload a file programatically and occasionally I get the
following error message.
Unable to write data to the transport connection: An established connection
was aborted by the software in your host machine.

The source code for FTPClient.cs came from the following URL
http://www.codeproject.com/vb/net/FtpClient.asp
The exception is been thrown when trying to write the Stream.
rs.Write(content, 0, dataRead)
Has anyone got any Idea why this might happen and how to solve it?

- Microsoft Project >> Dragging Finish DateIn a Gantt view of my project (MSP2000), when I try to drag the Finish
date of a task, the whole task moves instead of increasing the
Duration. This happens for any task I try to change.
If I create a new task, it behaves the same until I set the Constraint
Type to As Soon As Possible. The task Start date automatically
changes to the Project Start date. Only then I can drag the finish
date to extend the duration.
In a new project file, I can drag the Finish Date as per design.
Help?

- Net Framework >> Is this s bug?Hi All
I have one query, and need urgent help here. It is related with Windows
Address
Book(WAB). Suppose I open a link to WAB through my application's (developed
in VC++) dialog box. Now, if I get the focus back on my dialog box with the
WAB still opened(not in focus though), I cannot navigate through the
controls in my dialog box through the TAB key. Also, ENTER key does not
work. But the dialog box starts responding to the TAB and ENTER keys as soon
as WAB is closed. Why is it happening like this. I had downloaded a sample
WAB program from www.microsoft.com and this program too had the same
problem. I want to know if it is a bug or a normal behavior in VC++ and WAB
integration. Is there any workaround to this problem.
Thanks for your time.

Hi All,
I'm trying to generate a C# wrapper for a Windows type library using the =
following command line ...
csc /target:library /doc:Interop.MyLibrary.xml /unsafe =
Interop.MyLibrary.cs >Interop.MyLibrary.log
And receiving the following error message ...
Interop.MyLibrary.cs(499,18): error CS0536: =
'Interop.MyLibrary.IImpBaseCollection_SinkHelper' does not implement =
interface member 'Interop.MyLibrary.IImpBaseCollection.Item(object)'. =
'Interop.MyLibrary.IImpBaseCollection_SinkHelper.Item(object)' is either =
static, not public, or has the wrong return type.
Here's the code....
The line where the error occurs is in Bold Blue
Any ideas appreciated!! ;-)
Thanks,
Roland

- Dotnet >> Process CPU usage jumps to 100% without any reason?I am working on an application in c# that runs in the background.
All it does is monitor a value from a performance counter using a timer. It then draws these values in a chart
Now, this application works for a long time, sometimes even days. But sometimes it just freezes and the CPU usag
spikes to 100% for that process. I really don't understand why, and there seems to be no actual event that trigger
this. It looks like this problem occures more when I am using more CPU power during a long period of tim
(f.e. when compressing something). But even then, sometimes the program freezes and sometimes it keeps running
smooth at 0-2% usage..
Is there anyone that can give me an idea on how to solve this problem
I thank you for your time
Kind regards

There should have been no problem with Project 2000, or 2002 reading a
recurring task. I suspect a file corruption. Try emailing the file again.

- ADO >> Visual Studio 2003 Issue - Error when defining TableMappings on DataAdapterWe recently upgraded our MSDN Version of VS.NET 2002 to VS.NET 2003...
Things are all working well, except we've run across a new bug or issue
since our adopting of the new package.
Before I give the error message, let me preface it with a brief description
of how our 1-tierd data environment is setup. (Note: we do get the same
errors on multi-tiered apps as well and originally it was thought that our
error lied in the way we were having our dataaccess objects inherit
connections from base objects... but anyway, it's not ... ).
In a typical web application of ours, we have an appsetting called
"MainDBConnection" within the Web.Config file. The data w/in the variable
looks something like this:
<add key="MainDBConnection" value="data source=OurServerName;initial
catalog=OurDB;persist security info=False;user
id=mikej;password=mypassword;workstation id=MIKEJ;packet size=4096" />
The connectionString was one that was actually generated by VS.NET and then
copied/pasted into here. Anyway, in the designer, and connection that is
defined points to the value through the Dynamic Properties -->
ConnectionString area of the Properties Window... Everything looks good...
it retrieves the value from the Web.Config and any command object works
nicely w/ it... nicely meaning that I can define queries in the designer and
VS.NET can communicate w/ the DB for parameter generation and all that
jazz...
Here's where the problem comes in... Ok... so imagine I've defined a
connection object (pointing to my config data), a command object (pointing
to the connection) and a dataAdapter (using the command object as its
SelectCommmand Property) ... When I click on the button to define
TableMappings in my property window for the dataAdapter I get the following
error:
Unable to retrieve the schema from the database table. Source column
mapping information will not be available. Would you like to continue?
What!?!? This is where I'm confused... VS.NET can access the DB when I'm
defining my Select Command's CommandText property. Why can't it when I'm
defining my tableMappings? Another thing that confuses me is that
everything worked fine in the previous version of VS.NET... Bug addition? ;)
It's probably some bad convention I'm using in setting up a dynamic
connection, but if anyone has a way for this to work, pleeeeeeeease let me
know. Additionally, whenever I open up an object like this in the designer,
I get another error saying, "Exception has been thrown by the target of an
invocation" and then the designer erases my table mappings again and I have
to repeat the whole annoying process of having to fix it again... Funny
thing is that this is only new w/ version 2003 :( I shouldn't have upgraded
all my projects... Now I'm stuck with it and though I've developed many new
methodologies, I still have to figure out how to get this old stuff working
for maintenance purposes. I have figured out some workarounds for the
issue, but it's such a productivity killer to get it going again as I have
not found a consistent method for kickstarting it...
While I'm on the subject, I'll describe how I get around it. There are 2
ways I have taken care of this:
1. Add this to the dataadapter in the object constructor (This still doesn't
fix it working in the designer, but allows me to compile):
- MyDataAdapter.TableMappings.Add("Table", "MyNewTable")
2. If I really, really want my designer to work right, I can tinker around
w/ Visual Studio enough so that it prompts me for my SQLServer Username and
password (and I guess VS saves that info in memory 'til I close it)... after
that, the Designer's table mappings work again. How do you get that
user/password prompt you ask? I usually have to define a new connection for
the DB and then change it back after it has prompted me. This way works the
best, but is still just a big pain in the butt because everytime I *open* a
page in the designer it clears out my table mappings until I fix the
problem... again and again
Also, one thing that has already been suggested and tried is changing the
'persist security info=False' to True, but that didn't work either :)
Thanks for your time,
Mike Joseph

- Dotnet >> Logging Into a ServerHello All,
I'm hoping someone can point me in the right direction. This is outside of
my experience with VB. I have an application (written in VB.NET) that
allows a user to enter a part of the file name and all file matches in a
specific
directory are copied to the user's desktop. It's a simple but useful tool.
Now an outside company requires access to the data. The files have been
moved to a Windows 2000 server accessible via the internet (i.e. outside the
firewall) so the other company can access the files. Both companies are
going to use this program. Since this server is not on our (or any) domain
I must log into that server. Therein lies my question. How do I
programmatically supply a user name and password to the server? We do not
want the other company to know the user name and password to the server.
The "best" solution is a web application, but I need to get this working
immediately and I haven't much experience with ASP.
Thank you for your help.

- Microsoft Project >> error: valid product key must be set to create an admin imageI'm trying to set up an administrative installation point for project 2002
professional including MUI-packs (german; maybe french, too). When installing
the MUI-Pack to the administrative share using the usual command
"<cdrom>:\1031\setup /a"
the setup stops after completing all dialogs (accept, installation path)with
installer error
"A valid Product Key must be set to create an Admin image"
I was never asked for a licensing key and IMHO the MUI kits don't handle
licensing, anyway. I'm using Project 2002 pro with volume licensing key and
the MUI CD2 from MSDN Subscriber Downloads. Poject 2002 us-english
kernel runs without problems.
It's independent of the installation path I choose.
Ideas?

but everytime( when the text filed with the path is empty or filled) the if
statement works in same way.
How could be checked if the path is filled or it isn't?
Here is my code.Thank you in advance!
private void Button1_Click(object sender, System.EventArgs e)
{
msg.Text="";
if(filMyFile.PostedFile != null)
{
try
{
// Get a reference to PostedFile object
HttpPostedFile myFile = filMyFile.PostedFile;
// Get size of uploaded file
int nFileLen = myFile.ContentLength;
if(myFile.ContentType.CompareTo("image/gif")==0)
{
// Allocate a buffer for reading of the file
byte[] myData = new byte[nFileLen];
// Read uploaded file from the Stream
myFile.InputStream.Read(myData, 0, nFileLen);
string strFilename = Path.GetFileName(myFile.FileName);
string strDir = "c:\\Inetpub\\wwwroot\\Estates\\Files\\" +
Session["usrName"].ToString();
Directory.CreateDirectory( strDir);
string
strRoute=MapPath("/Estates/Files/"+Session["usrName"].ToString()+"/"+strFile
name);
//string strFilename = Path.GetFileName(myFile.FileName);
//string strRoute=MapPath("/Estates/Files/"+strFilename );
WriteToFile(strRoute,myData);
msg.Text="The file was attached";
}
else
{
msg.Text="This file is not a gif!!!";
}
}
catch(Exception exc)
{
msg.Text = "Error by saving: " + exc.ToString();
}
}
else
{
msg.Text="Please, atach your file!";
return;
}
}

- ADO >> DataTable LimitationsI've found a MSDN reference to the fact that an ADO.NET DataTable is limited
to 16,777,216 rows of data [1], but what I cannot find is a reference for
the maximum columns per DataTable, maximum bytes per DataRow, etc. Is this
information documented anywhere?
TIA!

- Dotnet >> Generate Expressions in a datasetHello there,
I was wondering if anyone knows if there is an easy way to import
expressions into my typed dataset from the original view/sql statement
For example if I drag a view from the server explorer onto my dataset I
would like it to import not just the caculated field but also the expression
that creates the field.
I think that an ORM mapper would probably do this for me but unfortunatly I
am stuck with datasets :(
Any ideas would be much appreciated, thank you

- ADO >> database formatsTrying to compile a document of all industry standard database formats. I can
think of SQL Server, Access, DBASE, SyBASE, Oracle, and ASCII .
Does anybody know other formats or where I can get a description of database
formats?
Asking partly out of curiosity and partly because I'd like to tell my
customer all the database formats my wonderful ado.net application will be
able to support.
thanks!

- Net Framework >> Disable / Enable single grid cellHi
I use a datatable as a datasource in my datagrid (win form).
I want the user to be able to edit certain columns but not in every
row.
anyone have a good idea how to do this?
So far I have tested to set the datasource to
Row.Table.Columns[ColumnID].ReadOnly = false;
but as you all probobly understand this causes that column to be
editible in every row..
I can't use .net 2.0 as this is a requirement so far.
Hope anyone has a good idea.
Daniel
