If picViewer is a window or dialog it is never being created therefore the CStatic child window is also never created so IsWindow(m_hWnd) returns false and Asserts during debugging.

<br />
cam1.Create(IDD_PICVIEWER,0); <br />
cam1.EnableWindow(TRUE);<br />

<br />
cam1.show(buff,numRead);<br />

picViewer is the class that is related to the picViewer dialog.

void commanding::load()
{
UpdateData (TRUE);

FILE *pic, *pic1, *pic2;
picViewer cam1;

In the first code you posted:


void commanding::load(){UpdateData (TRUE);FILE *pic, *pic1, *pic2;picViewer cam1;


that instance of picViewer is local to that function so it is not related to anything else.

int commanding::loadCmdGet3CamData()<br />

	pic2 = fopen("C:\\cv\\8_8.jp2", "rb");<br />
	unsigned int numRead;<br />
	cam1.Create(IDD_IMAGEVIEWER,0);<br />
	cam1.EnableWindow(TRUE);<br />
	int i = 0;<br />
	while(i < 3)<br />
	{<br />

Is there a header file that CSemaphore requires to be #included?

I read this documentation earlier

but not the "Microsoft Platform SDK for Windows Server 2003 R2". I just thought that has got to do with Server stuff.
