Re : ClipboardPutBitmap and Webbrowser

[Bertrand_ENAC]

Hi,

I'm using the Webbrowser ActiveX for selecting a location with Google Earth. Then I would like to make a bitmap from this control and add it as a background to a graph.

I use the functions GetCtrlDisplayBitmap and ClipboardPutBitmap but the result is not correct

Instead of that:

I get that:

Is this normal behavior? Is there a way to achieve my goal?

As a work arround I thought to make a sreen print but how can I crop the image to the part I would like to keep?

Hi,

Maybe you should try something like that (in this example, "ok_cb" is a callback function linked with any "ok button" on your user interface) :

int CVICALLBACK ok_cb (int panel, int control, int event,
		void *callbackData, int eventData1, int eventData2)
{
	int bitmap = 0, plotHdl = 0;
		
	switch (event)
	{
		case EVENT_COMMIT:
			
			GetCtrlDisplayBitmap (panelHandle, PANEL_WEBBROWSER, 0, &bitmap);
			plotHdl = PlotBitmap (panelHandle, PANEL_GRAPH, 0.0, 0.0, 0, 0, NULL);
			SetCtrlBitmap (panel, PANEL_GRAPH, plotHdl, bitmap);
			
			break;
	}
	return 0;
}

GetCtrlDisplayBitmap : get webbrowser image

PlotBitmap : please see the last parameter (NULL) help -> "You can pass NULL or an empty string for filename. This capability is useful when you want to define the image at a later point in your program by calling SetCtrlBitmap on the plot handle this function returns. The plot is not visible until you specify a valid image."

SetCtrlBitmap : please see the third parameter (plotHdl) help -> "For graphs, the plot handle you obtain from PlotBitmap."

Hi Julien,

Thank you for your suggestion.

Unfortunately we already tried your proposol and the result remains the same, the picutre in the Webbrouwser is not captured.
