Hello Everybody,

My question is that how can I capture the graphical screen which I created in C. I make my project using graphics command and i want this program screen shot but I dont know it's procedure. Can any one know how to capture graphical screen.

When I create program without using graphical command i can capture the output screen using PRINTSCREEN keyword in the keyboard. But when I converted it into graphics mode. It doesn't work

So Please tell me how can I capture or print the graphical output screen.
If you know any keyword which capture the graphical mode so tell me as far as possible.

I will be very thankful to you.

Regards:
Rockey

So, do you need a screenshot of your program that's written in C, or do you want to write code into your program that will take the screenshot for you?

Well I completed my project yesterday, know i want the output picture of my project but i don't know how to capture it.

Printscreen key is disable in graphical mode. So You know any keyword to capture the graphical output window so please pass it to me.

Hi there!

I am not a developer, but from the automation testing point of view, were I in your shoes, I would put some snippet that will call some external program like SnagIt (or use GIMP) which in turn will make a screen dump.

Lemeno if this does not help, I will think about it more.

I know you can do this with C++ not necessaarily with C as I haven't tried it, but:

What about creating a context that covers the whole screen, then blit it to another device context for saving or printing?

edit: Here's a snippet along that thought process:

CODE

CWindowDC dc(NULL);   // use NULL to get whole screen
CDC memdc;
... // create, initialize memdc
memdc.BitBlt(..., &dc); // copy screen contents
