Well this is the problem, you don't have to do this...
Why don't you try the code that I gave, and try to see the difference.

I was missing this little gem LPRECT lpRect = ( LPRECT )lParam;
Thanks alot,
It seems that the rect which GetWindowRect sets doesn't actually get used after my WM_MOVING hanlder is complete.

Read what MSDN says about lParam as on WM_MOVING event...
<code>lParam: </code>
Pointer to a <code>RECT </code>structure with the current position of the window, in screen coordinates.
<code>To change the position of the drag rectangle, an application must change the members of this structure.</code>

I need to learn fast about the creation of ATL Composite Control Projects.
Where could I find abundant information about this??.
Maybe a tutorial in the WEB.
Maybe a book.
I have read a lot about ATL projects but I need something specific about Composite Controls. Something that teach me how should I move inside this kind of project.
I have some good skills with MFC and I'm learning general ATL stuff.
Thank you very much.
Demian.

hi good day to everyone. why do i have this kind of warning to my functions?
warning C4100: 'nFaceRecNo' : unreferenced formal parameter
what does it mean? thanks for your reply 
positive vibes
|
|
|
|
|
It means that the parameter "nFaceRecNo" isn't used in the function. The best way to get rid of this warning is as follows:
void Foo(int n)
{
}
void Foo(int)
{
}
Note that in the code without the warning I've removed any parameters which I don't use in the function from the function definition. It can still be present in the declaration. There are other ways of resolving this problem but this is how I normally deal with it.

We have several VC7 MFC and ATL applications and are wondering whether to port them over to VC8. The main reason is so that we don't have a mix of development environments - some projects using vs2003 and some using vs2005.
But are there any advantages as far as the libraries go - STL/ATL/MFC? I understand the main change is in the C runtime string functions to reduce buffer overflow problems. Any other changes for better or worse?
|
|
|
|
|
Yes, basically if you use C string functions, you'll get a warning. Beyond that, I see no compelling reason to change, there are some breaking changes for standards, but all reasonably obscure.

Sir,
I want to learn how to make a web application in vc++.net.
Please send any link .
Thanks.

I don't believe you can use C++ for ASP.NET. Your profile says you know ASP.NET, why do you want to write a web app in c++ ?

Hello everyone!
OK, I've been making posts about this specific mother-freaking hair-greener problem, but now I got it just where I want it: I got it down to a 34-line file, no references to it in the rest of the program, just included once in my Includes.h file... Here it is:
<br />
#ifndef _MAPHANDLING_H_<br />
#define _MAPHANDLING_H_<br />
<br />
namespace MapHandling<br />
{<br />
struct TileFile<br />
{<br />
SDL_Surface *layers[4];<br />
<br />
int s, w, h;<br />
<br />
TileFile() : s(0), w(0), h(0) {}<br />
<br />
TileFile(int size, int w, int h, const std::string& filename) :<br />
s(s), w(w), h(h)<br />
{<br />
layers[1] = IMG_Load(filename.c_str());<br />
<br />
if (!layers[1])<br />
exit(0);<br />
}<br />
} Tilesets[1];<br />
<br />
void LoadTiles()<br />
{<br />
Tilesets[0] = TileFile(24, 3, 2, "./Graphics/Tiles.png");<br />
}<br />
};<br />
<br />
#endif // _MAPHANDLING_H_
Note that the exact same thing happens on both VC++ 2005 and Code::Blocks. (Different error messages, of course, but same idea)
These are the VC++ errors:

If I remove the #include to this file, it compiles zezw. (Zero Errors, Zero Warnings).
Can anyone tell me what's the problem? I have another file that does the same thing, so I'll post it if needed... Thanks!

Aha! The problem is with variable and function declaration... Look:
<br />
#ifndef _MAPHANDLING_H_<br />
#define _MAPHANDLING_H_<br />
<br />
namespace MapHandling<br />
{<br />
struct TileFile<br />
{<br />
SDL_Surface *layers[4];<br />
<br />
int s, w, h;<br />
<br />
TileFile() : s(0), w(0), h(0) {}<br />
<br />
TileFile(int size, int w, int h, const std::string& filename) :<br />
s(s), w(w), h(h)<br />
{<br />
layers[1] = IMG_Load(filename.c_str());<br />
<br />
if (!layers[1])<br />
exit(0);
}<br />
} TF;
<br />
void func() {};
};<br />
<br />
#endif // _MAPHANDLING_H_<br />
Look at the lines with the HERE on them... Those two cause trouble (a few redefinition errors). So, anyone guess what's wrong? Thanks!
(PS: I doubleposted because the first post would look too long...  )

Hello all,
I've downloaded Visual C++ Express Edition for the first time and I enjoy programming with it. I have a question that I can't seem to figure out. Everytime I start a new C++ project, I have to constantly write the preprocessor directive "#include <iostream>" in my programs. How do I go about starting new projects with this directive already included in my programs? Thanks!
