Dongsheng,

From the message subject, it looks like you are programming in CVI. Is that the case? If so, there are several examples of how to acquire and display images into objects that are embedded on the user interface. On your computer, try navigating to:

C:\Program Files\National Instruments\CVI71\samples\IMAQ\Display

Take a look at the examples located there, especially Snap ImgPlot and Snap Canvas. Those examples both show embedded image display windows.

Thank your advice.
But you may not understand my meaning.I programing with labwindows/CVI and Imaq vision ,my Image caputre board is not the ni product.
I want to use the Imaq Vision function on the image window, and I met the problems mentioned before.

Dongsheng,

What method are you using to display images? Are you using a graph or a canvas? Please be more specific in describing how you are displaying images to the user interface of your CVI program. What function are you calling? What parameters do you use for that function?

If you are not using an NI board, how are you getting your image data into CVI? Are you using Vision functions to display the image or are you using software that is specific to your board?

Please give me more specific information about how you are planning to display the image.

What method are you using to display images?
(I display image in the image window using the imaq vision.)

Are you using a graph or a canvas?
(So, I dont use a graph or a canvas.)

Please be more specific in describing how you are displaying images to the user interface of your CVI program.
(Firstly I made a decoration control and I want to place the image window in it.Then I get the location of the decoration and move the window there. I want to use the image window because I can use many function (in the imaq vision). The problem is that When I finish this, and run the program, I found there is the taskbars of the program and the image window, and CLICK the imagewindow taskbar, the image window minimized, and there is three panels in my program, the image belong to one panel. I want it display when i call the panel and hide when i hide the panel, I use the function imaqSetupWindow (VISION_WINDOW, 😎 to let it display on top, but another problem come out, when I open other software(such as Internet Explorer) and let the program keep running, the image window still on the top, that is boring.)

If you are not using an NI board, how are you getting your image data into CVI? Are you using Vision functions to display the image or are you using software that is specific to your board?
( I use other image borard getting the images, I make the image board save the image and then read image using imaq vison function.)

I do not know whetehr the upper description is specific and do you understand my meaning, I am sorry for my poor english?
Thanks again.

Dongsheng,

The best method to use here would be a combination of the "Load and Display" example and the "snap imgPlot" function. From the snap imgPlot code, we want to use the GetPanelAttribute (panelHandle, ATTR_SYSTEM_WINDOW_HANDLE, &CVIWndHndl) function to obtain the window handle of the main interface and assign that handle to CVIWndHndl. This handle is assigned by Windows and it uniquely identifies the specific window that has the Canvas control and user controls on it. We can then use this window handle in the imgPlot function as imgPlot (CVIWndHndl, ImaqBuffer, 0, 0, acqWinWidth, acqWinHeight, CanvasLeft, CanvasTop, plotFlag).

This will place the newly acquired image onto the user interface instead of into a separate window. In the case of that example, it places the image on top of a canvas control. In your case, you can use the top and left values for the decoration that you have placed.

Try this and let me know if you have any additional questions on this issue.
