first-chanche exception in CVIRTE.DLL

[scantool]

Using Labwindows/CVI User Interface Library in a MS VC++6.0 project, with a 1600x1200 resolution CVIRTE.dll throws an exception when calling a LoadPanel() function:

"first-chance exception in PCScanTool.exe (CVIRTE.DLL): 0xC0000005: Access Violation"

int CLabWnd::MyLoadPanel(int nPnlHnd,char filename[],int nPnlResId)
{
int nErr;
nErr = LoadPanel(nPnlHnd,filename,nPnlResId);
AddErrorString(nErr,"- Modulo LabWnd.cpp Classe CLabWnd Metodo MyLoadPanel");
return nErr;
}

The problem doesn't appear with different resolutions.

Hello

Which version of CVI are you using? and Which OS? Do you have a test app I can use to reproduce the problem?

Thanks

And another standard question: do you have the latest video driver for your video card?

[scantool]

The version of CVI is 6.0.
The OS is XP Home.
The test application needs an hardware designed by Upix elettronica s.a.s. and it is not possible to send to you.

I've attached a project i used to try and replicate the problem. Let me know you you can build this and use it to see the problem on your machine.

I didnt see this happen on my machine. I have XP Pro, tried it with CVI 6 and 7.

Thanks

Bilal
