Thank you.

I guess the code is fine as is. I really wasn't checking on the mem usage in task manager but was looking for something there and noticed the usage kept increasing.

How am I supposed to change the strFileName and load different files inside the loop?

If you need to load a new file, the resources has to be properly released if it's anymore used. So please release the buffers and handles associated with
LoadFile operation. I think the other part of the code is just fine.

I used the following sample code to do it.

I am not sure what I am looking for in order to release the handles.

Thanks for you help in advance.

HBITMAP test = m_bmpCtrl.hBitmap;
		if (test)

Can someone please help

What's the type of m_bmpCtrl variable? There will be direct functions exposed in the class to clear the attached resources

also the way you released the resources is quite wrong. if you're explicity releasing the resource, it's your responsibility to assign it as NULL. Otherwise the next call this function may crash, as you've released the previously and the m_bmpCtrl.hBitmap still holds an junk(invalid) handle. also why it's necessary to create a temporary variable? the following way is straight forward no?

if (m_bmpCtrl.hBitmap)
			{
				DeleteObject(m_bmpCtrl.hBitmap);
				m_bmpCtrl.hBitmap = NULL;
			}

Thank you. That has partly solved it. Yes there was no point creating extra variable.

The m_bmpCtrl is of CBitmapCtrl class.

I am new at this and am learning. Thanks for all your help It's greatly appreciated.

I have an client application which as files i need to copy the a selected file into clipboard and paste it on the desktop or any where outside my client application
Within my client application i am able to copy and paste files but not outside my client application.

Here is the code
void SetClipBoardStringData(CString str, int format )
{
EmptyClipboard();
CString text = str;
HANDLE hGlobalMemory = GlobalAlloc(GHND, (DWORD)(text.GetLength()+1));
HANDLE lpGlobalMemory = GlobalLock(hGlobalMemory);
memcpy(lpGlobalMemory,(text),(text.GetLength())+1);
SetClipboardData(format,lpGlobalMemory);
GlobalUnlock(lpGlobalMemory);
GlobalFree(hGlobalMemory);
}

I am calling this function.
SetClipBoardStringData(sStrXML,CF_TEXT);
This copies the sStrXML to the clipboard.This sStrXml contains the file contents.
Now i want this clipboard contents to be availale outside the application so that i can paste it another application like notepad or a file in desktop.
How do i do it?

Try passing hGlobalMemory instead of lpGlobalMemory in SetClipboardData function.

Ummm - access permissions?

You know, most Windows functions return error codes and set the thread's error status (see GetLastError[^]), just so that you can tell why failure's occurred....

KarstenK told you that there are separate 32- and 64-bit registries. That says to me that your desire isn't going to be fulfilled. Get over it and use a file instead - I believe Microsoft kind of recommend using files for configuration information (rather than the registry) these days.

I am beginner in VOIP.I try to make simple calling and answering application.
Here i face this problem -I can hear only one side(calling).

Please check this following code.

// Get the ITCallNotification interface.
IDispatch* pEvent=(IDispatch *)lParam;
Answer(pEvent);
}
break;

Can you help me how it resolve.
