Visual C++ 2005 giving me a hard time

[hellochar]

Hi, I've been a Java programmer for 2-3 years now, and over the summer I am trying to learn C++. I hear they're basically the same thing, and I've gone through some online tutorials and the like. The problem I have today is one with Windows Forms. For those of you who know Java, it's easy enough to make something graphical. My first attempt at a real program in Java was a simple program where you drew with your mouse, so I'm doing the same for C++. But I have a problem. With Java, it's easy enough to make a "Form" by creating a JFrame and retrieving a Graphics object. But in C++ I have no idea how to do that, and I'm getting lost in Visual C++ 2005 express edition. I don't usually like to use the GUI builders, so I'm attempting to avoid that, but I can't seem to get a window to show in C++ without the builder... can anyone help me?

Right now, through using the builder, I can create a method that fires off when the mouse moves.

private: System::Void mouseMoved(System::Object^  sender, System::Windows::Forms::MouseEventArgs^  e) {
				 if( e->Button == System::Windows::Forms::MouseButtons::Left) {
					 System::Drawing::Graphics g = this->CreateGraphics;
				}
			 }

I have some questions about the code:

• What is sender?
• The compiler gives me errors when I try to compile the line after the if statement. I know I'm doing something wrong with pointers, can someone tell me the problem and possibly a solution?

Thanks

The sender is the object that triggers the code. Usually the EventArgs are more useful than the sender, but every event handler tends to have one.

Could you post the error message it gives you with the line after the if statement? I think it might be because you don't have #using namespace System; near the beginning of your code.

Nevermind, I figured out my issue (i was doing "createGraphics" instead of "createGraphics()"). thanks guys, appreciate the help and I'll probably have more things to ask in the future

No probs. In older versions of VB and things you could get away with not using () but in .NET it is mandatory.

There's a newer version available for download on Microsoft's website (free):
Microsoft Visual Studio 2008

I can't see much difference between versions 2005 and 2008.

[dargueta]

I've never had the 2005 version, so I wouldn't know.

I have. I really can't see the difference between them.
