if (hDLL!=NULL)

  ....

else
{
   printf("DLL not found !!!\n"); <- ERROR : GO HERE WITH VS2005 DLL !!
}

May be i understood wrongly, he was saying failed at loading library.

re -

thank you for your interest. My team continues to search but without success for now...

1. I have a problem to load library - not (yet) to import functions but thanks for typing Iain Smile | :)

-> My boss has migrated the DLL on his computer and compile it. When I tried to compile his solution with VS2005, it doesn't compile.

So i assume Replay.dll is produced by the compiled version (Boss').

hello everybody !

>> just a guess, have you installed the VC Redistribute [^]

I have installed the VC Redistribute yes... But I found the problem.

You remember DLL (b) ? That was the DLL used by my DLL (a). The guy who has compiled the DLL (b) has VS2005 SP1 ! SP1 is important because it requires some other DLL to work! So, we had to check with Dependency Walker to get the dependant DLL and the manifest to get the DLL version. With a lot of research we have finally found all DLL. That's all ! Cool | :cool:

I have a last problem. I still cannot compile the VS2005 project (which is a project migrated from VS2003 by my boss). I get the following error:

<br />
Error	2	fatal error C1902: Program database manager mismatch; please check your installation	c:\MyProject\stdafx.cpp	1	<br />

This project compile correctly of my PC's boss. What do you think ?

Thanks for you help,

string operation and related exception

Hello everyone,

I made some self-study of the possible exception from string operations. I want to let you review whether I am correct. Since I can not find any exception information from MSDN. Talking in Visual Studio STL environment is ok.

1. assignment, may throw bad_alloc?
2. comparison (compare), nothrow?
3. insert, may throw bad_alloc?
4. concatenation, may throw bad_alloc?
5. replace, may throw bad_alloc (suppose replace small sub-string to large sub-string)?
6. find (e.g. find_first_of), nothrow?
7. substr, may throw bad_alloc (sub-string is something new)?

thanks in advance,
George

basic_string constructor

Hello everyone,

I want to study the constructor for string to see whether for an empty string it has some default storage allocated or not (for self technical interest only), and string is defined based on basic_string<char>, so I begin to study basic_string.

But in file string, there is no constructor for basic_string. Anything wrong? Where is it?

I am using Visual Studio 2008.

thanks in advance,
George

Hi Jeet_IT_in,

I am confused. CString is class for MFC, but string is STL class. Are they related? Thanks.

There is the constructor of std::basic_string in VC++2005.

File xstring, line 583.

__CLR_OR_THIS_CALL basic_string(has_debug_it _Hdi = _Has_debug_it(true))
  : _MyBase()
{
  // ...
}

I have found 16 bytes will be allocated as default. Right?

I think along with this STL stuff, learn something on debugging. Place the breakpoint on the statement, then step in, step in, you can explore the complete available code.

Problem in Closing a file window.

Hi,

In my application i am opening a text file in one window.
In the middle of some operation / implementation i need to close this window and i need to open the same file again. When i tried to close this file (i tried with the function CloseAllDocuments()) it is deleting the contents of some structure variables related to my application. Is there any way to close this file without deleting the contents of these structures variables ???

Regards,
Sanjeeva Kumar.

Sounds to me like you answered your own question. If your document class is cleaning itself up, that would seem a fitting place to start looking. Have you implemented DeleteContents()? What about OnOpenDocument()?

WM_TIMER message never arrives [modified]

In my Win32 application, I register several window classes, each class have a different message procedure. Then, I create several windows.

I call SetTimer(m_hWnd, SPECIFIC_MESSAGE_CONSANT,1000, NULL);

As far as I know:
This should send a WM_TIMER with wParam = SPECIFIC_MESSAGE_CONSANT, with one second time delay.
To the message procedure of the window class that m_hWnd (HWND) was created from.

where SPECIFIC_MESSAGE_CONSANT = 11761

In my int APIENTRY _tWinMain()

I do:

MSG msg;
   ZeroMemory( &msg, sizeof(msg) );
   while( msg.message!=WM_QUIT )
   {
       if( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
       {
       //my WM_TIMER dont get here
           TranslateMessage( &msg );
           DispatchMessage( &msg );
       }
       else
        {
       }
   }

WM_TIMER never arrives to the place marked above.

I tried PostMessage(m_hWnd,WM_TIMER,SPECIFIC_MESSAGE_CONSANT,NULL) ->
got exactly where expected.

Still, I must have the time delay.

This can lead to busy loop, as peekmessage returns without waiting for messages. This may not be the problem. This can use significant processor time.

Are you creating the windows in the same thread as the message loop?

I was sure that my message peeking loop was pretty standard. I can't see the problem you indicated.
Please describe it if you have the time.

Rajkumar R wrote:

I dont do any special threading now, working pretty standard so I guess I am creating the windows in the same thread.

please note: all other messages (automatic-win32-messages) arrive where I expect them.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
