Hi,
I need to create new thread if I click on particular button in my MFC application.I have added following code.
AfxBeginThread( CRuntimeClass* pfnThreadProc,LPVOID pParam,
int nPriority = THREAD_PRIORITY_NORMAL,UINT nStackSize = 0,
DWORD dwCreateFlags = 0,LPSECURITY_ATTRIBUTES lpSecurityAttrs = NULL);
UINT CTestcycleDlg::pfnThreadProc(LPVOID pParam )
{
}
I am getting errors one of thoes error is
error C2275: 'CRuntimeClass' : illegal use of this type as an expression <br />
I have created user interface thread.Is it correct.Where I need to close thread and how to close

Haven't you tried CreateThread[^].
But be careful to terminate thread. For that you can see this[^].

I am using MFC.I think I should not use createThread.

You can use createThread method.There is no matter of MFC.

You are correct, you should NOT be using the CreateThread()[^] Win API version if you are using MFC (Again, look at the remarks section of CWinThread class to know why).
But, if you want that kind of functionality (which you may need with UI threads), you can then create a CMyThread object and then call CMyThread::CreateThread() when you want the thread to start execution. (CMyThread is a CWinThread derivative.)

Your method which will work as thread & belong to class then it must be define static. But is method is not belong to any class then it is no matter to have static.
hemlat wrote: AfxBeginThread( CRuntimeClass* pfnThreadProc,LPVOID pParam,
When you pass pointer/name of method use CTestcycleDlg::pfnThreadProc.
I hope this will work for your code.

What is this? Are you trying to call AfxBeginThread(), or just duplicate the prototype?

Still?! Are you kidding me?
I gave you link to an excellent UI thread tutorial yesterday. Did you read it or not? Why are you "searching" for code, BTW? You're supposed to write code if you are a programmer of any kind.

Bookmark the MVP Tips[^] page. There's plenty of good essays there.
Look for "Using Worker Threads" essay for your purpose.

Did you even bother to read the article that Rajesh provided? If you had, you would have noticied a link to this.

Hello,
I am dealing with a problem and I would need your help.
I have two top most windows, and i want to always have one of the windows in front of the other. The solution that makes one of the windows a child of the other cannot be applied in my case.
Thank you for your help.

You could use the topmost style (See SetWindowPos) for the Upper window, but it's not a very scalable solution (2 works, 3 would not)
I'd have another look to see why making one a child of the other would not work first before you kludge it.

Thank you Iain for your answer. The solution with one child of the other works perfectly, but the reason why i was searching for another solution was that the number of windows involved isn't in fact 2, it could be bigger, so i will need to change dinamically the parent of my "upper" window. You said to use the topmost style, both of the windows are made TopMost using the SetWindowPos method. You mean maybe the WS_TOPMOST style.

|

I meant ::SetWindowPos (hWnd, HWND_TOPMOST, ...), but was being sloppy about it.
If it's N, then you'll have to get over your aversion to windows being children of other windows...

hence I am not able to figure out the problem. Could any one help me please?
void InstallPptAddins(LPCTSTR strAddinPath)
{
CFileFind m_fileFind;
CString strAddin;
PowerPoint::_Application Ppt;
PowerPoint::AddIns m_pptAddIns;
PowerPoint::AddIn m_pptAddIn;
if(!Ppt.CreateDispatch("PowerPoint.Application"))
{
Log("Error:fn::InstallPptAddins() Couldn't open Powerpoint Application\n");
return;
}
try
{
if(Ppt.GetVersion()=="12.0")
{
PowerPoint::Presentations m_Sets(Ppt.GetPresentations());
PowerPoint::_Presentation m_Set(m_Sets.Add(TRUE));
strAddin = strAddinPath;
strAddin += "DSAFO5PP.ppa";
if(m_fileFind.FindFile(strAddin))
{
m_pptAddIns = Ppt.GetAddIns();
m_pptAddIn = m_pptAddIns.Add(strAddin);
m_pptAddIn.SetLoaded(FALSE);
m_pptAddIn.SetAutoLoad(FALSE);
m_pptAddIn.SetRegistered(FALSE);
m_pptAddIn.SetLoaded(TRUE);
m_pptAddIn.SetAutoLoad(TRUE);
m_pptAddIn.SetRegistered(TRUE);
Log("AFO Powerpoint add-in is added.\n");
}
else
Log("Couldn't find Powerpoint add-in %s\n",strAddin);
}
catch(...)
{
Log("Error::Couldn't install Powerpoint add-ins.Please add it manually\n\n");
}
Ppt.Quit();
