Hello there,

I am relatively new to the newsgroups and C#. I have never been disappointed
with the groups and always got the prompt replies to my queries.This is yet
another strange issue, I am facing. Please please help me to solve this as
soon as possible.

So here we go ...

I am not able to take the screen shot of the windows form based "Smart
Client" application at run time.This is urgently required for making the
presentation .

Till now I have tried 4 methods...
--------------------------------
1) Using IrfanView software
2) Using Snag-it
3) Using Camtasia_Capture&menumaker
4) Using the program which is given below...

Problem  Description
----------------------

These programs are taking the screenshots of the wallpaper behind the
windows application along with the mouse cursor .So it is apparent that
mouse is clicking on the particular points of screen where menus or button
exist in my application but doesn't take the screen shot of form. Isn't it
strange? Also these programs are taking the snapshot of other windows based
application.

I am able to take the snapshot of my application (which is not visible to
above programs) using "PrintScreen" and pasting it in the paint.Also I am
able to take the snapshots of some of the forms of application (using above
4 programs), which have a label to display the message and some background
image setup at runtime.

Let me tell you that my windows application uses the skins which can be
changed dynamically using XML and there are few background images setup at
runtime for the forms. I think that the problem is because of some property
of the application or windows form.

I believe that I have described the problem well enough to understand. Now
the ball is in your court. Please help me..........
