How to use imgPlot in a MFC SDI program to show image in main window

[ATMCBAIN]

I am trying to display acquired images in the main window of my Single Document MFC application as opposed to individual display windows. I use imgPlot to achieve this. The problem seems to be the HWND that I pass to the call. I am not sure of the proper place or technique to capture this handle.

Hello,

Have you tried looking in the IMAQ Function Reference Help? You can locate this document by navigating to Start >> Programs >> National Instruments >> Vision >> Documentation >> NI-IMAQ Function Reference. This help file contains descriptive information for each parameter of the function.

I would also suggest taking a look at the IMAQ examples that shipped with NI-IMAQ. You can find the C examples in the following directory:
C:\Program Files\National Instruments\NI-IMAQ\Sample\MSVC

I would suggest starting with the HL Snap example. That is a very simple example that snaps a single image and displays it.

Take a look at that documentation and at those examples and let me know if you have any additional questions.

I have gone through the examples. I actually have a working application that uses a good portion of the capabilities. For some odd reason though, I have never been able to get this to work. I think its how or when I go about getting the m_hwnd or it may be a painting issue. I do not get any errors from the imgPlot though.

Hello,

Could you give me more detail as to how you are obtaining the handle? Are you using the CreateWindow() function? This function should return a handle to the window that is generated. This should be usable for the window input of imgPlot(). CreateWindow is a Windows Management function that should be available in Visual Studio, so information about using that function should be available in the Visual Studio help files.
