Hi,
Thanks for your suggestion. It's working. I am using following code.Is this correct code?
CToolTipCtrl m_tooltip;
m_tooltip.m_hWnd = ::CreateWindowEx(WS_EX_TOPMOST,TOOLTIPS_CLASS,NULL,
TTS_NOPREFIX | TTS_ALWAYSTIP,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,
this->m_hWnd,NULL,NULL,NULL);
::SendMessage(m_tooltip.m_hWnd, TTM_SETMAXTIPWIDTH, 0, SHRT_MAX);
CString text;
text.Format("Tool-Tip \n OK");
m_tooltip.AddTool(GetDlgItem(IDC_BUTTON1), text);
Best Regards,
Aniket

hi all 
can somebody explain what is a .lib file ?
what advantages it has when using in projects , against simple classes .cpp and .h files?
thank you.

A library is used by your project to load particular symbols (funcions or variables). It contains compiled code.
In brief the purpose of the lib file is to provide a 'package' that can be reused in several applications without divulging the source files (only headers are supplied).

It means instead loading the .cpp and .h files to his project, he will be including the header file only ?
and writing
#include someClass.h
Does the .lib file have to be in the same directory as the project ?

.cpp -- Simple C++ implemenation File
.h -- Header file
.obj -- a description of the program suitable for linking
.lib -- an index of the contents of a dll used by the linker
.exp -- an index of the symbols exported by a dll
.exe -- an executable program
.dll -- a dynamic link library located at run time using PATH env variable
.def -- a text file which tells the linker what to put into a .dll

A lib is not always associated with a dll. You can simply have a static library that export symbols without having a dll. The difference is that the code of your lib file will be 'added' to your application at link time (unlike a dll, which is at run-time).

In addtion to what cedric has said,lib files are used to link the DLL implicilty.
your .h -> .lib ->.dll .

 Really ? .lib and .dll are two complete different things to me. A .lib is sort of a collection of .obj, and a .dll is, well, a .dll. Completely independant. So the .lib ->.dll, I do not understand ...

If you want to implicitely load your dll (so, include the header files to your app and not call LoadLibrary and GetProcAddress), a lib file is needed. Dll and lib files are not so different, the only difference that I know is that the lib will be added to your app during the linkage of your app, and the dll will be added at run-time.

lib and .dll are completely different .
The .lib file is a file that has the stuff the linker needs to build your executable program. Windows cannot use them, but compilers and linkers can. Its a lot like a .obj file really, except it contains everything needed for all the stuff in your 'library' whereas an obj is from a single source file. It also contains a protocol for the associated .dll (basicaly, offsets of where functions start, the name and parameters(?) of the functions, calling conventions(?) and things like this).
A .dll can have a lot of different stuff -- data, functions, anything really. A dll that has shared routines is what the OS needs to run those routines -- compare this to a 'mini executable'. A program smoothly jumps from its own executable statements to the ones in the .dll and back again. Windows does some smoke and mirrors here to make the file loading efficient(ish).

Yup, he's(cedric) right. When you make use of the .lib file, you can call the function in the dll as if it's available as a location function. You don't need to go in for LoadLibrary , GetProcAddress which would otherwise become an "explicit" linking.

Hi Cerdic and Vunic,
While working with dlls, do we need to explicitly copy the .lib file along with the dll file in to the path of the exe?
if not, how it is going to be linked in the Project->Settings->Link ?
Appu..

NiceNaiduWhile working with dlls, do we need to explicitly copy the .lib file along with the dll file in to the path of the exe?
No, only your dll is needed in the folder of the exe once it has been compiled.
NiceNaiduif not, how it is going to be linked in the Project->Settings->Link
Yes, you have to specify that you link to this specific library in the settings of your project.

Yaa..Now i got it..Thanks Cerdic.
Hey Rage, Is it clear now ??

Otherwise you'd get a typical Linker error.

NiceNaiduHey Rage, Is it clear now ??
Quite, thank you.
Here we work with microcontroller, no windows stuff. We are using libs as well, and libs are really only a collection of .obj with a header and entry points for the linker (actually we also have a locator, this is the step you do not need with .dll).
I did not know about the fact that you can simply add a .lib to get direct access to the .dll.
Thanks to Cedric and Vunic as well.

lib is only required while linking(creating .exe) once it is linked even if u delete the lib the program will execute
never say die

Hi !!!
An .lib file is an static library. It can contain some .h or .cpp or .inl, ... files. It is a library, so it is no executable file. You can use it for build libraries, for example : STL, boost, ...

Hi,
On Windows Xp, there is a functionality that allows to copy the archives of an user. This functionality is had access through My Computer ( click of the right button of mouse ) -> Properties -> Advanced -> User Profiles -> Settings -> Copy to.
An example:
There is user called João. In the directory c:\documents and settings\João\ are the João user's files. I just want to copy them to another directory. This functionality, as i said, is had access by My Computer -> Properties -> Advanced -> User Profiles -> Settings -> Copy To, but i want do that by C++ programming.
I was thinking in something like a method of a WMI Class or the ShellExecute command.
I'm watting for help!!
gratiful!
Hélio

This does not seem to be available on my windows XP. Just found it, lost a bit of it during translation (my computer is in german).
Anyway, do you have an idea what it copies ? Is it only the directory under C:\Users ?

CString m_Username = "test";
how i use Getlenght() to find the number or letters ?
|
|
|
|
|
 
I think it's pretty obvious no ?
int Count = m_Username.GetLenght();
MSDN[^] are also very usefull.

GetAt() returns the character of type TCHAR of the Given index parameter of GetAt() function
