Hi

I am trying to call SelectRegionTool and expecting to region coordinates to changed after I secect the area, but it's not happening, I always capture the full desktop.

Please, help, I am using Mulimedia sdk 14.5.

here is the code I am trying to use:

Dim lmScreenCapt As LMScrCapLib.LMScrCap

lmScreenCapt = ltmmScreenServer.GetSubObject(LTMMLib.ltmmCapture_Object.ltmmCapture_Object_VideoCaptureFilter)


'ltmmScreenServer - is a capture control on the form
ltmmScreenServer.EnterEdit()

lmScreenCapt.CaptureFrameRate = 8
lmScreenCapt.EnableRegion = True
lmScreenCapt.SelectRegionTool()

ltmmScreenServer.LeaveEdit()


Thank you.

When the user draws the region on the screen after you call SelectRegionTool(), the values selected are sent to a callback function that you can set using the SetCallbackObject method. Your callback function code decides whether to set the property values to the newly selected values or not. It is not done automatically.

Igor,
We currently don't have a sample. Did you try to implement a callback function?
If you couldn't get the callback to work, I can try to create a sample for you. Are you using VB6 or VB.NET?

Igor,
I created a demo that uses the Screen Capture Video Source Region Callback in a simple VB.NET project.
The callback is needed to set the values selected by user using the interactive Region Tool.
The demo is attached with this post.

File Attachment(s):
VbDotNetScrCapRegion.zip (7kb) downloaded 24 time(s).
