I'm surprised it even runs if you're missing things.

Search for vcredist.exe or mfc redistributable to find a program which installs all the needed MFC files.

You have tested your file out as a release, rather than a debug executable?

Have you looked back on your developement PC to see what is in Winocc.cpp:345 ?

No, he is using VC6, not VC2005. That also explains why it runs.

Could you paste the line on which you have the assertion. I don't have VC6 installed and the winocc file is different for VC2005.

That will at least give a little clue of what might be the problem.

Yes, I think you forgot either to copy it on the target machine or to register it with regsrv32 (or both).

if you linked the MFC library dynamically, the provide MFC42.dll with your exe, + the few other dlls the system requires...

That's probably not the problem because then it would have complained about missing dll's and not give an assertion.

As Cedric has prodded me, some more thoughts...

The redistributables haven't been necessary for a long time now. If your program runs, you don't need them.

I stand by my second point...

Looking at winocc.cpp:345...

/////////////////////////////////////////////////////////////////////////////
// CWnd invoke helpers for OLE Control wrappers

void AFX_CDECL CWnd::InvokeHelper(DISPID dwDispID, WORD wFlags, VARTYPE vtRet,
	void* pvRet, const BYTE* pbParamInfo, ...)
{
	ASSERT(m_pCtrlSite != NULL);    // not an OLE control (not yet, at least)          <--- line 345.

	if (m_pCtrlSite == NULL)
		return;

	va_list argList;
	va_start(argList, pbParamInfo);
	m_pCtrlSite->InvokeHelperV(dwDispID, wFlags, vtRet, pvRet, pbParamInfo,
		argList);
	va_end(argList);
}

It looks like you're using some COM object that you haven't installed / registered / ask politely on your new system.

Now you just need to track it down. I find remote debugging a bit of a nuisance, but a godsend at times like this.

Assertions are part of debug builds.

Yeah, but he had to ship the debug build, may be because the release build was crrrashhing when it starts. Big Grin | :-D

Hi,

To solve my problem...Finally I installed VC in the system.Now the assertion error is not coming..its working.
But comunication is not working in COM port.

I create Dialog instance like this..

pDlg = new CMSCOMMDlg();
pDlg->Create(IDD_MSCOMM, this);
pDlg->OpenPort();

void CMSCOMMDlg::OpenPort()
{

m_Comm.SetCommPort (1); // Com port 1
m_Comm.SetSettings ("9600,e,8,1");
m_Comm.SetInputMode (1); // Binary mode
m_Comm.SetPortOpen (TRUE); // Open it
}

And i use this coding to glow LED in External keyboard conneced in serial port.

void CMSCOMMDlg::OnButton1()
{
// TODO: Add your control notification handler code here
//OpenPort();
CByteArray btArray;
btArray.Add (0xC5); // Byte 1
btArray.Add (0x0C); // Byte 2

COleVariant var(btArray);
m_Comm.SetOutput(var); // Send the data.
}
But the signal is not reached to keyboard.
I dnt know why this problem? still im searching for my problem.

But this EXE is running perfectly in my system(development system).

Drop List in a Combo Box

Hi
Can anybody help me with the following puzzling problem?

I have created a dialog using Visual Studio 2005 (MFC) and added a combo box to it. This combo has been set to type Drop List and I have set the list box height at design time by clicking the arrow and changing the height of the "ghost" image. I have also set the Vertical Scroll to True.

I have populated this with more items than should be possible to display in one go. However, when I run it, no scroll bar appears!!! That is, it simply drops down with all the entries.

Can anybody tell me what I've done wrong and ideally reproduce the problem as I'm going slightly crazy!!!

Thanks

Paul
