23-Feb-02 1:49

Hi,everybody here. I'm very sorry I am a Chinese boy. So I have poor English level to understand the means in this wonderful websuit. But I like this web very much.

But now, I have some difficult in creating my DLL files. The question is: Could I create DLL file with Borland Turbo C (version:2.0)? And can I use Visual C++ to write C code? Haha... I have more question about C/C++,do I? Haha... There is another question that can I use Visual C++ to create my DLL files and use it in the Visual C++?

Thanks a lot!!

Hi, my good friend. Thanks for replying my question. And you know I am a beginner. So I don't know how can I improve my programme level. You know, in china, computer is not populer.
And the computer is very expensive in China. So Chinese software is do not famous in the world. So can you tell me what can do improve my programme skill? And what kinds of books I should read?

OK! finally, Thanks a lot.
And this is my E-mail address: alpha_8848_prince@hotmail.com

Hi:

Its good to begin from some online books,I wanted to email them to you but all of them become
too large,so I put their link here and you can download them.You can read one or two of them,then
begin to practice,and here,codeproject,is best place to solve your problems,and also find
lots of tips,sample code and ...You can read them and use them in your programs,and then
you will improve step by step.
My suggestion is after reading one of these books,focus on one field,for example database or user interface or ATL.
Here are the links:

Simply name your file with a .c extension rather than .cpp, and DevStudio will use a C compiler in order to compile that file. You will need to be careful if you are trying to mix C compiled code with C++ compiled code however, because the C++ compiler will mangle the linker symbols in order to make function overloading possible.

Hi,

This must be really simple, but I am struggling with this. If I have a string such as:

TCHAR hex[] = "0AF79E00";

How can I convert this into a long variable so I know it means:

184,000,000

Is this possible? Confused | :confused:

Thanks in advance,

Simon

int value;
sscanf(hex, "%X", &value);

How create a pie or chord region

I don't know how create a custom region!

thanks a lot!

You can call BeginPath on a DC, Then you could call your pie or chord function, and then End the path with EndPath, the path is stored inside of the region. Then you can call PathToRegion on that DC and a new region will be created with that path.

nothing appear!

What's wrong with these code?Nothing appear in the screen!!!

void CMysView::OnPaint()
{
	CPaintDC dc(this); // device context for painting
	paintrect()

}

int CMyView::paintrect()
{
	CPaintDC dc(this);

	RECT rctA;
	rctA.left = 20;  
	rctA.top = 30;  
	rctA.right  = 180;  
	rctA.bottom = 230;


	dc.Rectangle(&rctA);

	return 0;
}

I think you're supposed to do your drawing in CView::OnDraw instead.

You get the paintDC twice in the same WM_PAINT message, afai remember that's not allowed and the second one won't work. If you passed the dc as a parameter to CMyView::paintrect instaed I bet it would work.

void CMysView::OnPaint()
{	
   CPaintDC dc(this); // device context for painting	
   paintrect(dc)
}


int CMyView::paintrect(CDC& dc)
{	
   RECT rctA;	
   rctA.left = 20;  	
   rctA.top = 30;  	
   rctA.right  = 180;  	
   rctA.bottom = 230;	
   dc.Rectangle(&rctA);	
   return 0;
}

Cheers

You can pass the DC from OnPaint to your other drawing functions... so paintrect(CDC *pDC)...
