View Full Version : DshowLibException VB6

Hello ,

i m facing a problem that i can't solve and i need your help.
I have a DMK 51AG02 monochrom and i try to run the first sample program
Open Device
If ICImagingControl1.DeviceValid Then

ICImagingControl1.LiveDisplayDefault = False
ICImagingControl1.LiveDisplayHeight = ICImagingControl1.Height
ICImagingControl1.LiveDisplayWidth = ICImagingControl1.Width


but when tries to execute .Livestart gives me this error
An unexpected DshowLibException occured Error= Failed to start the graph. Due to Unbekannter Fehler
In file : "Filter Graph.ccp" at line 307
It can recognize the device in VB,no problem for this.

Thanks in advance

Do you have Imaging Control 3.2 or the Active X version 3.2? Also, does the pre-compiled demoapp worK?

all version are 3.2.
i made some changes in the properties of IC1(VB6-form) and now it works!
I reset in old properties settings to find where was the mistake but worked and with the old properties...
i cant explain it...but its ok now!!! :)
thanks again for your time!
