Something like that ! To understand what i am saying , i will tell you that i read all about and i try all the programs from forum.ni.com , but nothing works ! I need a webcam.vi program in Labview 8.2 because my all project(i graduated automatic faculty )  is in labview 8.2 . I made un program in labview 8.2 that compare some object , so i need this program to see my driver webcam to capture and save a picture where i want ! 

I have labview 8.2,8.5, 9 ...in labview 9 , the program that you sugest to me give me an error when i try to save him for labview 8.2 ! 😞

Thank you for trying to help me . So , about the  http://forums.ni.com/t5/LabVIEW/2-hours-finished-the-webcam-program/m-p/906890/highlight/true#M40866... is working for me , but only in Labview 8.5 or higher ...

I have download from this forum some webcam program and i save it from 9.0 to 8.2 ..it seems that it works for me : it see the camera , but when i want to snapshot the picture , it gives me this error :

"Error 1172 occurred at Error calling method System.Windows.Forms.IDataObject.GetData of NULL ObjectId, (System.ArgumentNullException: Key cannot be null.

) in webcam_fernando_saveas.vi
Possible reason(s):
