Re: DO YOU WANT TO HELPP? helpp me - C / C++ / MFC Discussion Boards

I have made all the necessary registry entries to associate my app with a project file that it creates. When I double click on the file my app starts up but I get an invalid path error when opening the file. Once the application is running, however, I can open the project file without any problems. I am getting the file name from the m_lpCmdLine variable in my CWinApp derived class.

Does anyone have any suggestions how to resolve this problem?

Thanks.

Does the path contain spaces?

why don't you use your debugger for this ?
you could check where something is lost.

what i suspect is that you have spaces in your file path, and passing it through the commandline will not work since you don't put the path within quotes ("").

Yes, some kinda of debugging: for instance printout (maybe with a message box) command line content.

I managed to solve the problem. For those who are intrested I did the following:

CommandLineInfo cmdInfo;<br />
ParseCommandLine( cmdInfo );<br />
<br />
CString strProjectName = cmdInfo.m_strFileName;

This works without any issues.

Thanks.

An OLE container? Have you tried importing from PowerPoint's type library?

Yes,but all applications are MFC based

But the code that actually communicates with PowerPoint is not.

I just created a Win32 project, opened ClassWizard, clicked the Automation tab, and created an Excel class from its type library. It worked fine.

I have also created a non MFC win32 Project but i can't add class from type library using class wizard.

I Think you have created MFC based win32 project.

If i am wrong please tell me the detailed steps.

Lay out the exact steps you are using.

You would be wrong in your thinking.

Which shows nothing of how you are attempting to create the PowerPoint classes via ClassWizard.

I want to change background color of ListCtrl.
I try to use this function

<br />
m_List.SetBkColor(RGB(76,85,118));<br />

but no work

Please advise me for this issue,May be it need more of code

Thanks

add message OnCtlColor
and add this code inside:

<br />
	switch(pWnd->GetDlgCtrlID())<br />
	{<br />
	case IDC_LIST1: <br />
		pDC->SetBkColor(RGB(0,0,0)); <br />
		hbr = ::CreateSolidBrush(RGB(0,0,0)); <br />
		pDC->SetTextColor(RGB(0,255,102));		<br />
		return (HBRUSH)hbr;<br />
		break;<br />
}<br />

then you are there where you wanted;)
