Capture image in C#/Vb.net in wind 8.1 64bit.

Prakash Sir thank you for your reply and sorry I wasn't well since I couldn't checked out the links you had given, Well I'll  try now thanking you so much

Hello Gowtham,
May I know the value/purpose of your two reply (copy paste from my reply)?
I think, It's better to not reply if one doesn't have anything new.
Hope you will take it positively.

Hi, avicap32.dll seems to be not compatible with newer OS. You may think of using one of the option for Image capture in Windows 8.1
1. DirectShow dll (http://sourceforge.net/projects/directshownet/files/)
2. Microsoft expression dll (comes with Microsoft Expression 4)

Have a look at below post for more details.

Using DirectShow:

Using Microsoft expression:

Hope this helps.

First of all, I would like to say Prakash sir thank you for the time taken to read my question as well as to reply, Well I'm using "avicap32.dll" to work on. Now I have downloaded the code from"http://lobsterproductions.weebly.com/downloads.html" the given link but little change of L.O.C(Line Of Code) I have made. and this works fine in Win Xp/Vista/7 as well, But When ever I'm trying to work on Win 8.1 64bit, Whenever form gets loaded for the first time it captures the Image/Photo and using savefile dialogbox I'm saving picture into the drive after saving picture into drive when I hit the "start" button on the Form1 it is showing a pop up window saying that "Select a video Device" and when I select the d"USB2.0 Camera "and hit a apply button then there is no flow of camera on the picture box of the form1. 
Thanking you once again .

What's exact error you are getting? You may try to share the piece of code which now stopped working.
