Select recommendation, timescale from audits, auditItems where
AuditItems.ParentAuditID = Audts.AuditID and Audits.SupplierId = '" &
ComboItem.Value & "'"
So what do i set tablemappings to?
I usually do this:
myDataAdapter.TableMappings.Add("Table", "Audititems")
but that doesnt work... Any ideas?
Thanks,

- ADO >> Serialized Typed DataSet VersioningHello all,
I'm working on a smart client application for my company. The client
uses .NET 2.0 typed datasets to store it's data. It works both in
'online' and 'offline' mode. When the application starts in online
mode it gets a new dataset diffgram from a web service. When it shuts
down in online mode it sends the changes made to the dataset to the
server and gets a new dataset. In offline mode it, when shutdown,
persists the typed dataset to disk as encrypted XML. The next time the
application starts it reads, decrypts, and sends any pre-existing
changes to the server and gets a new dataset.
My problem:
If there are schema changes made to the typed dataset in, say, version
2.0 it may make the locally persisted dataset written in version 1.9
unable to be loaded into the new version and data could be lost.
Because losing data is totally unacceptable to the business in this
case, I've got to find a way to load that older version's dataset and
then convert it to the new version then send it to the server as the
new version's type.
Any ideas on typed dataset versioning?
Thanks for your help,

- Visual C#.Net >> Cannot call Invoke or InvokeAsync on a control until the window handle has been createdHi
I am having this InvalidOperationException with message Cannot call Invoke
or InvokeAsync on a control until the window handle has been created
This is raised when i try to invoke a method with arguments
I need to do this as the method is being called Asynchronously from
elsewhere using delegate's BeginInvoke method.
The form is well created/initialized yet the messages states otherwise.
Cant extract a sample code out of my app.
Let me know if the code is needed for the problem.
All controls on the form are in a panel. The form itself isnt show, but the
panel is shown as a child control of some other panel. Can this be the
problem.
Thank you

- Winforms >> Problem with forms not properly disposedTo be able to explain what's happening, I will use a short example:
The example is created in VB.Net 1.1.
I have a form with a combobox on it. The datasource is set to a global
datatable object which is instanciated on a vb module.
I instanciate the form, set the datasource, valuemember and displaymember on
the combobox. Then i dispose the form. After the form is disposed and I do
any changes to the global datatable (e.g. clear all rows), the
SelectedIndexChanged event on the combobox is still triggered.
How is that possible?
Any help would be appreciated.

- ADO >> Extra DataColumn's in DataTableHave a strange problem using a sproc to populate a DataTable.
The sproc itself is fairly simple and returns a selection of columns from
three tables, a master table and two additional tables which are joined via
a LEFT JOIN.
The resultant DataTable schema after a fillschema looks good however after
a 'fill' the DataTable has two extra columns at the end which represent the
unselected columns from the two LEFT JOIN tables. These columns do not form
part of the SELECT statement yet are appearing in the DataTable with all
values set to null.
I have tried the same query with a DataReader and see the correct columns
(obviously executing the same sproc from query analyser shows the correct
column set) therefore it appears to be a DataAdaptor issue which is somehow
pulling down these unselected columns. This problem is a right pain as the
I am binding a DataGrid to the DataTable via a DataView and the extra
columns appear at the end of the grid.
I know I could remove the columns via TableStyles however I might change
the database schema at some point and I would need to know dynamically at
run-time which columns were garbage and at the moment I can't see any
properies on these columns which I could process against.
This looks like a bug to me therefore interested if anyone has come across.
Can post sample code (c#) and sproc if anyone would like to see.
Regards

- Winforms >> Click Event HandlerI have a C# .net 2003 program that has a processing loop in a click event
handler for one of the form's controls. The loop has a DoEvents
and a Thread.Sleep for each iteration to simulate a lengthy process. I want
to be able to have the user click a cancel button to set a flag to stop the
looping but I have found that the first click on another control while in
the click event of the first control is not caught by the program. Sometimes
takes many clicks to work at all. Does anyone know what is happening here ?

- Winforms >> Access to the internal property grid combo box controlAbybody knows how the PropertyGrid manage the ComboBox control?
I know to use the TypeConverter so the ComboBox are used if the user clicked
in the property. But I want the access to window control so I can use the
void WndProc(ref Message m) method of the ComboBox.
Thanks

- Winforms >> No Touch Deployment Error QuestionHI,
I am getting this error when I try to create a new instance of one of my
forms.
--
System.Security.SecurityException: Security error.
--
This error is thrown in the CTOR on the MyBase.New() call.
At this stage I have already created and displayed several other forms right
before this step, so it doesn't make sense why this particular form would
fail it is just a Standard windows form, with Menus/toolbars on it. It
doesn't even tell my what kind of security error
TIA,

- Winforms >> New to WindowsFormsHi I am learning windows fomrs and started with the sample in the quickstart
tutorials and I am not able to display the control on my aspx page.
I created a control library with one simple control having a panel and a
button. panel's visible property is false by default and I added color to
panel.
On the button press event , I set the visible property of the panel to true
to show the panel.
This control is created as test1.dll and then added to a web application and
added to aspx page as an object and calling with the classid property to
display the control. I have also set the objects property "VIEWASTEXT' .
The problem is that the aspx page does show the placeholder but does nto
display the control.
what am I doing wrong?
Please advice.
thanks

- ADO >> SqlDataAdapter and DataSetWhen you call Fill method passing a DataSet object and table name, is that
table name associated with the SQL Server table name or just the moniker
that will be attached to the generated table inside thee DataSet's
TableCollection? What if you call Fill() without passing a table name, does
SqlDataAdapter generate some name?

- Microsoft Project >> Project 2007 Not Enough Memory to PrintOur schedule won't print more than once at a time. If we do a print preview,
it won't print at all. The message, "There is not enough memory to complete
the operation. To free up available memory, close programs, projects, or
windows you aren't using, and then try again." I can close all but Project,
and it still won't print. The only thing that works is to close Project,
reopen it, then open the project without previewing it. It prints fine, but
cross your fingers. If it is two pages wide, you won't know until you waste
a ream of paper.

- Dotnet >> icon for desktop shortcut not workingHi all,
I am attempting to deploy a vb.net application. That is working fine.
I also configured the installer so shortcuts for the application
would appear on the desktop and the user program menu. That's working
too. What isn't working is the icon that I am setting for these
shortcuts. The icon is a .ico file that works fine for the program
itself, and for any shortcuts that I manually create. After I created
the shortcuts of the primary output in the file system editor, I set
the icon property to my .ico file. However but the shortcut s that
result from installation still show your basic, generic "file" icon.
Anybody have any idea why the icon isn't appearing on the shortcuts
created by installer? I followed the .net help file instructions
exactly!
thanks,

- ADO >> Column Expression questionHello!
After filling table into DataSet (ds), I added following line ...
ds.Tables(0).Columns("MyColumn").Expression = "<MyFormula>"
... and calculation is working fine - but I need to save this calculated
field value into database also because it makes easier to make SELECT
queries later and it's quite often needed value in many cases too. This
"MyColumn" is as a field in database too, and is used too when making
DataAdapter in SELECT-query.
When trying to save, I'll get error message ...
"The column mapping from SourceColumn 'MyColumn' failed because the
DataColumn 'MyColumn' is a computed column."
Is it possible to save computed column values into database table at all?

Thanks in advance!

- Visual C#.Net >> Windows Services and System.Web.UI.Page.RequestHi.
I am wondering how to handle AbsoluteUri values inside windows
services?
It seems that the absoluteuri is called from the System.Web.UI.Page
namespace
which is not allowed inside a windows service (that I am aware of).
But, I need to call the following inside my service:
Request.UserAgent,
Request.UserHostAddress,
Request.Url.AbsoluteUri
Since I can't use the Request object (in the sense of
System.Web.UI.Page),
how do I access the above values from within my service??
Thanks for your help.

Specifically: on the the Directory Securty Tab (right click on a folder
under the Default Web Site) click the edit button next to Anonymous access

I know in the end we are really just changing/entering data in the IIS

Thank you so much for taking the time to help....I'm really stuck on this one.

- Visual C#.Net >> Running code compiled in Framework 1.0 with Framework 1.1Hello,
We have an application written using Framework 1.0 (VS2002), we have
deployed it to a server that only has Framework 1.1 installed, the
client does not want to Install Framework 1.0 because it might have an
impact with other .Net applications written using Framework 1.1, so
rather not getting into a debate with the client I have agreed to
investigate if we could get our application to run using Framework 1.1
without recompiling it. Is this possible, if so how?

- ADO >> Problems with return parameter from Oracle functionI have an oracle function that looks like this:
AuthenticateUser(UserName IN VARCHAR2, pPassword IN VARCHAR2, AppName IN
VARCHAR2) RETURN VARCHAR2
Using the Oracle client provider, I'm setting up my command text as:
:results = call AuthenticateUser(:username, :password, :appname)
I then add parameters as follows:
OracleParameter p = new OracleParameter("results", OracleType.VarChar);
p.Direction = System.Data.ParameterDirection.ReturnValue;
p.Size = 255
xcmd.Parameters.Add(p);
xcmd.CommandText = _authenticateCall;
xcmd.Parameters.Add(new OracleParameter("username",
OracleType.VarChar)).Value = "abc";
xcmd.Parameters.Add(new OracleParameter("password",
OracleType.VarChar)).Value = "123";
xcmd.Parameters.Add(new OracleParameter("application",
OracleType.VarChar)).Value = "Test";
However, when I execute the command, I get an ORA-01036: illegal
variable name/number exception.
If I leave out the :results paramater from both the command text and
don't add it to the parameters of the command, then I can call the
function w/o the exception. So it seems like .Net can't figure out how
to bind my parameters correctly (this is more or less confirmed by the
stacktrace of the exception).
In every example I've seen, this is the recommended way of calling a
function. What am I missing that would make it bind the return parameter
correctly?
