The above line should be
bRet = BitBlt(hdcOld,0,0,width,height,hdcMem,0,0,SRCCOPY);

Does hdcOld support BitBlt? You may check it with GetDeviceCaps.

Next time you should say "Please EDIT your message and use the code block button to post code snippets" :P:P:P:P

Is it possible? I've been trying to send the object for some hours but I dont think it is possible since as far as I've read, the device context data lies on a different part of the memory.
What I am trying to achieve is to send a CDC object from one application, to another almost every 200ms (the application which sends the CDC is hidden btw). I currently have 2 solutions so far (Use of 1. Clipboard, 2. Shared DLL) but I want to make sure first if there are other better ones out there. Hoping for your suggestions.
Thank you.

Why do you want to do such a thing ? 
|
|
|
|
|
part of the requirements given to me. never would think or might want to do that thing myself anyway 
one application is more of a graph maker and another is more of the overall application which manages all the dedicated applications (one is the graph maker).

I have a histogram of grayscale image
range of value 0 - 255
the question:
How to calculate mean of that Histogram (grayscale image) by using iterative segmentation.
If U give me script of visual C++ for this, I will be glad and thanks for all.

Like Histogram on the Photoshop?

I mean that a image actually has histogram.
and the question is, how to Calculate mean of image Histogram by using such formula.
Do u know about this formula and how to apply in visual c++ using iterative method?.

Please let me know what are the requirements to create a game in VC++. By requirements I mean like SDK's or game engine's etc.
|
|
|
|
|
Depdends a lot of the type of game you want to write. 2D or 3D ? You want to use DirectX or OpenGL or something higher level ?

Choosing the right SDK or a game engine depends on game requirements.

Suppose I want to make a 3d car racing game. Then in this case what things I need to be know. Please give me some examples of the requirements needed.
|
|
|
|

Do you want to start from scratch and write your own 3d engine ? This is quite complicated and very long but you'll learn a lot of usefull things (and chances are you won't finish the game since it is already something very complex on his own).
You could also use an existing 3D engine. Some that comes to my mind: Ogre, Irrlicht, TrueVision. Check if what they can satisfy your requirements.

Probably you should use DirectX or OpenGL libraries.
Please note yours is a daunting task, see, for instance [^].

Here's a simple C++ game:
#include<iostream>
using namespace std;
void main()
{
while(true)
{
cout<<"You're plzying cool - bezt player!"<<endl;
cout<<"Oh my God... press enter again LOLZ..."<<endl;
cout<<"You're liking the gamz#$$";
}
}
Seriously, you at least need to tell what is the game that you're talking about.
Ok, everytime I enter aa code with anny of the #include starters, i get 103 errors and 2 warnings, and then I look for them, and it opens a new window "tab" thingy, and otsream, or istream or math or w/e i am using comes up. It makes testing fully written programs impossible to test. Does anyone know how to fix it?? - A query asked on the VC++ board[ ^]
