The support for XML documentation provided by the C# compiler is very nice... using the xml output it produces combined with a tool like NDoc[^] creates very nice "MSDN-looking" documentation. Or if you don't want to use NDoc, you can always create your own XSL stylesheet to process the xml documentation.
It's too bad that the VB.NET compiler does not support the same feature. You may want to look at the following:
http://vb-doc.sourceforge.net/[^]
http://www.fesersoft.com/products/VBXmlComments/[^]
http://vbxmldoc.tor-erik.net/[^]
I haven't used any of these, so I can't offer a recommendation. But one may be what you're looking for.

How can i compare the value of a Current cell to Previous one in all of my row That are displayed in a datagrid? I got this result but I am Looking for a way which should be more efficient than mine.

Maybe you should check the cells before they are displayed in the datagrid. Usually there is a recordset or an array attached to it. It's easy to compare these. But perhaps this is not your question.

I am working on a project in which we have to provide a UI to user in which all frames belonging to a selected mpeg2 video file are displayed. User then assign some attribute to each frame and then we have to store that video with those attributes added to each frame. Can any one give some idea about libraries or API's or controls which can help us.

Hi all,
Im currently developing a MFC-program in Visual C++ 6.0 that will identifiy a user through his/hers fingerprint.
The C++ program needs to be launched from another program with VBA support (so Im currently testing it in MS Excel)
The C++ program also needs to return a textstring with the username (or ID or some kind of text like "George Lucas")
With my very basic skills in VBScript I have manged to run the C++ program. But is it possible to get something back from the program ??
Im guessing that the C++ program might need some kind of method to communicate back to the VB Script ... ?
Im would be very thankful for any kind of help !

I have a VB project that loads a C++ DLL.
Declare the following module level API functions in your VB project.
' -- Windows API
Public Declare Function LoadLibrary Lib "kernel32" Alias "LoadLibraryA" (ByVal lpLibFileName As String) As Long
Public Declare Function FreeLibrary Lib "kernel32" (ByVal hLibModule As Long) As Long
' -- Public function in C++ DLL
Public Declare Function Test Lib "mycdll.dll" Alias "test_vb" () As Long
To use the C++ function you can use something like the following.
Note: strDLL holds the fullpath to the C++ DLL
' -- Load the dll
lngRet = LoadLibrary(strDLL)
' -- Check for success
If lngRet <> 0 Then
' -- Run the script
Msgbox Test
Else
MsgBox "Could not load dll '" & strDLL & "'" & DEF_SPACE, vbCritical, DEF_APP_TITLE
GoTo PROC_EXIT
End If
PROC_EXIT:
' -- Clean up
If lngRet <> 0 Then FreeLibrary lngRet

You can do that using the Exec method of the WScript.Shell object. The Exec method will return a WshScriptExec object that can be used to monitor the status of the running program, its exit code, and get to it StdIn, StdOut, and StdErr streams.
The docs on the WshShell.Exec method start here[^].
Dim WshShell, oExec
Set WshShell = CreateObject("WScript.Shell")
Set oExec = WshShell.Exec("MyCApp.exe")
Do While oExec.Status = 0
WScript.Sleep 100
Loop
WScript.Echo oExec.ExitCode

Getting access to the StdOut would be great, thank you very much !
*edit*
Got it working now, thanks a bunch !

If you change the Property Selection BackColor in the Grid Proerties page you can get your results. (If I understand your question properly)

Hi,
I am currently writing a utility to detect blank pages in tiff documents and delete them. I have a toolkit to manipulate the file but unfortunately it does not have a very flexible blank page detection routine.
So what I want to do is allow the user to set a percentage of black pixels parameter in a page and read the page data to look for the ratio of black to white pixels to determine if the page needs to be dropped.
The toolkit allows me to get the image data for each page into an IPicture but I am stuck from there on how to read the image data. Currently the system only needs to read black and white images (colour may be an option later but I will try to cross that bridge when I come to it)
So in short, can anyone help me in reading B&W data in an IPicture to count the black and white pixels?
Many thanks
Mark

I am migrating a large VB.6 solution to VB.Net and have encountered a problem that I haven't been able to solve.
It has been my habit for some years to notify myself of errors by putting up a new form and write to it the location and type of error that has occurred. This works nicely in VB.6.
I use this class in an error routine, such as.
Catch ex As Exception
Err.Showit("clsBars", "DoNewMinute", ex.Message.ToString)
End Try
In VB.Net the form comes up and is correctly sized and positioned and the error message is written to it.
When you pass the cursor over the form it turns to an hourglass. You can not minimize, maximize, close or drag the form.
If you use this class from a command button on another form with this code
Err.SetUpForm()
Err.Showit("This is a test")
the form behaves normally.
What am I missing?
Thanks
