i create two file one dll and one lib.i was told that i need to put the two files in my project and run the vcproj.
and after i open i will be see in the project propoty in the linker->input-additional dependencies my LIB file.
that was not happen.
i write manual my lib file .
now i get error message
"Error 50 error LNK2019: unresolved external symbol _showall referenced in function _WndProc@16 1.obj
"
and
"Error 51 fatal error LNK1120: 1 unresolved externals C:\Documents and Settings\bla\My Documents\Visual Studio 2008\Projects\12121sdf\Debug\12121sdf.exe
"
someone know how to do this correct ? (without the wizard in the vs)

I understand English may not be your first language, but it's hard to understand exactly what you're trying to do.
If you're trying to use a DLL, you need to tell the linker about it's associated LIB file. There's a couple of different ways of doing this:
0. Use a #pragma comment(lib,"path\mylibraryname.lib").
1. Use the linker properties in Visual Studio to specify the lib as a resource (as an additional dependency as you noted).
Now, I have no idea what you mean when you say "that was not happen. i write manual my lib file. now i get error message". It's not clear at all what you're trying to say.

it mean i try your suggestion number 1.and i get error message
now i try your suggestion 0 and i get error also
"Error 55 fatal error LNK1104: cannot open file 'C:Documents and SettingssafMy DocumentsVisual Studio 2008ProjectsQ21sdfQ21.lib' 12121sdf
"

Copy and paste the pragma comment you used... to see if you have something wrong in the syntax... also, make sure the file is where it's looking.
|
|
|
|

this is the error
Error 50 error LNK2019: unresolved external symbol _showall referenced in function _WndProc@16 1.obj
i try this option
#pragma comment(lib,"12121.lib")
and also
#pragma comment(lib,"C:\Documents and Settings\bla\My Documents\Visual Studio 2008\Projects\12121sdf\12121.lib")

You have to have the full path as you used in the second thing you wrote up there. Make sure the file is there and the file is accessible (not locked somehow).
This error:
Error 50 error LNK2019: unresolved external symbol _showall referenced in function _WndProc@16 1.obj
...means that it cannot find the showall function (with some decoration), this may be caused for a number of reasons, the function either doesn't exist in the library, or the settings between the lib and the executable that determine the function name mangling (or decoration) are different (see this[^]). You can avoid function decorations by importing/exporting functions using C-style methods for importing/exporting from libraries (which used no decorators at all). This may be your issue.
You had posted a different error before, so not sure if your linker is even finding the library file correctly.

Show us the contents of the 12121.lib file. Also, in the second case your path string is incorrect; each backslash in the path should be preceded by another in order for the character escape sequences to be correct, thus:
#pragma comment(lib,"C:\\Documents and Settings\\bla\\My Documents\\Visual Studio 2008\\Projects\\12121sdf\\12121.lib")
Note that this will fail silently as the compiler fails to validate this string.

Forgot about that... I almost always just use the lib name in pragma comments and add the directory as a "library directory" (since the compiled libraries are usually kept together, in my case anyway).

Yes, me too. Interestingly when I tested this although my string was wrong, the actual escapes were valid (\f and \b) so the problem was not diagnosed by the compiler.

Look at some of the articles here on CodeProject or search Google. Animation like this is not that difficult once you have learned the principles of Windows GDI[^] and/or GDI+[^].

in win32api
if i resize the window i want all the things i have inside to move also ,how can i do that ?
thanks
|

One suggestion would be to walk through the list of all child windows and call MoveWindow() for each of them to place them in new positions. If you are looking for a single API call to do this, I don't beleive such a call exists.

Chris is right... there's really no simple way of doing this... they have to be moved independently.

You have to move them yourself since there's nothing automatic in Win32.

See the Extras section of this article. It's MFC, but you should be able to accomplish the same thing with Win32.

wow i like this forum.
because i have an exam i dont have the time to check yours suggestion. i decide to limit the resize the window so i dont need to move anything.with this
case WM_GETMINMAXINFO:
{
LPMINMAXINFO pinfo =(LPMINMAXINFO)lParam;
if (pinfo!=NULL)
{
pinfo->ptMinTrackSize.x=750;
pinfo->ptMinTrackSize.y=550;
}
return 0 ;
}
thanks again

Hi,
The following code compiles no probs...
typedef struct SLLNode_t
{
void* m_pData;
struct SLLNode_t* m_pNext;
};
void foo()
{
struct SLLNode_t* pNewNode = (struct SLLNode_t*)malloc(sizeof(struct SLLNode_t));
}
The following, with a call to assert, generates a an error C2143: syntax error : missing ';' before 'type'.
typedef struct SLLNode_t
{
void* m_pData;
struct SLLNode_t* m_pNext;
};
void foo()
{
assert(0 == 0);
struct SLLNode_t* pNewNode = (struct SLLNode_t*)malloc(sizeof(struct SLLNode_t));
}
assert is defined as follows...
#define assert(_Expression) (void)( (!!(_Expression)) || (_wassert(_CRT_WIDE(#_Expression), _CRT_WIDE(__FILE__), __LINE__), 0) )
What is wrong? How do I fix it?
Thanks - John.
