Hi,
i have converted my application from VS 2003 to VS 2005 i am gettnig the error:
"PInvokeStackImbalance was detected
Message: A call to PInvoke function 'Senturion!SenturionFlash.KernelInterfaces::SetIssueEvent' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature."
i am using Vb.Net windows application.

If it's a Win32 API you are calling, try looking up the function on http://pinvoke.net/[^] and make sure that you declared it correctly.

You Declare'd the function incorrectly. Mostly this is because someone used the oold VB6 declare and tried to use it in VB.NET without knowing how the basic data types work. A Long value (32 bit signed integer) in VB6 is the same as an Integer in VB.NET. In VB.NET, a Long is a 64 bit signed integer. If the function you call pushes a 32 bit value on the stack and your code pops 64 bits off, you just imbalanced the call stack.

Hi,
your problem probably relates to the calling conventions (things such as CDeclSpec,
StdCall). Make sure your native code and the DllImportAttribute.CallingConvention
in your managed code are agreeing; I suggest to make them both explicit, i.e. not
to rely on default values here.

Can't you translate the C# to Visual Basic? Just re-arrange some stuff, remove some semi-colons, and then cheat with this page[^].

If it's only a few pixels you want, you can call GetPixel on the Bitmap object holding the screen image.

This is not easy. Unless the applications expose this information in an API (not many do), you're going to find this a huge pain. You have to get the window handle of the window that holds the control you want to get the value from. Then you have to go through the controls, an possibly container controls, to find the control you want, then send a WM_GETTEXT message to the control and get the value back. The problem is, there's no guarantee that the control in question will respond to the message!

I have a 32bit application built on vb.net2003 that uses the bundled crystal reports.
It installs and runs flawlessly on XP platforms.
when I install it on Vista Business (x64), the app runs fine, but any attempt to generate a report (that is, to instantiate a derived report class, as in, "dim rpt as new rptWhataver") results in
Cannot find KeycodeV2.dll, or invalid keycode.
keycodev2.dll is in fact present, and the app was built properly with the keycode property.
again, this app, and the reports work fine in about 1000 locations around the world on XP, win2k, and (gasp!) win98se. Anybody have a suggestion or work-around?

Hello,
I'm using VB.NET 2008 (framework 3.5).
I would like to check permanently if a new entry (row) is added to a table in particular, but I have no idea about how to do this... (is there some equivalent of the FileWatcher for DB ?...)
Thanks in advance

The service could periodically count (SELECT COUNT(*) FROM ...) the number of rows in the table and when the count increases you know a new row was inserted.
A better solution would probably be to use a FOR INSERT trigger on the table, as described by How to: Create and Run a CLR SQL Server Trigger[^].

ok, i'm going to try it (with the trigger).
thanks a lot !

Native in the VS toolbox?? No.
You'll have to either write one yourself or use a third party graphing library, like ZedGraph.

All you have to do is add entries to a collection. They can be as simple as adding string objects to a List(Of String), or an XML document. Either way, you can easily serialize the contents to a file to save/retrieve the list.

Hi all.
Do you now VB.NET is object oriented? I heard somewhere that VB.NET is text oriented. Is that true ? 
Thanks to you
|
|
|
|
|
Seriously? - Or just trolling?
|
|
|
|
|
YA dear vb.net is fully object oriented language.
Thanx
