Hello,
Thanks for all your replies
But I just got a new internet connection at home beacuse my earlier one was not able to send message to codeproject which really bugged me.I tried to send this message since I had nothing on my mind immediately.
Today I was more than happy since I could send the message after a long time from home and got all these replies in return.
Thanks for all the help you people offer.

So you thought posting a useless piece of trash was the best option? You could have at least made a comment in the lounge so you didn't look like a fool.
|
|
|
|
|
what about testing it in your own blog at your profile page?

Why you couldnt did you get any message when you wanted to post messages?
|
|
|
|

Hello,
When I used to post the message the site would not be connected and the message did not get posted.
The problem was only for codeproject otherwise yahoo,gmail would work.

Hi all,
I have a compiled dll (compiled by Marshall Soft lets call it m.dll) and then I have the code that compiled the m.dll (cpp,h,def). So then I compile the code to create a new dll(lets call it n.dll), I then view n.dll in Dependcy Walker all the functions being exported is there. The same happens when I perform the action with m.dll, but with the exception that the top panel shows additional functions.
Why is that, it is the same code but Dependcy Walker shows additional functions in the top panel. Is there settings one must set within Visual Studio ??
I hope this makes sense...

Are talking about the Parent Import Function List View? See Dependecy Walker help for explanations.

It's difficult to say without seing any code. It could be for example that some of the functions are exported when a specific macro is defined (something like #ifdef EXPORT_FUNCTION). This macro could be defined in the project settings rather than in a source file. Check for that.
You could also post the header file which contains the declaration of the functions which are missing when you build the dll. This will already help to start looking more into details.

Thanks for the reply Cédric,
Just a bit of the code:
#ifdef STATIC_LIBRARY
#define DLL_IMPORT_EXPORT
#else
#ifdef WIN32
#ifdef DLL_SOURCE_CODE
#define DLL_IMPORT_EXPORT __declspec(dllexport) __stdcall
#else
#define DLL_IMPORT_EXPORT __declspec(dllimport) __stdcall
#endif
#else
#define DLL_IMPORT_EXPORT FAR PASCAL
#endif
#endif
#ifdef __cplusplus
#define NoMangle extern "C"
#else
#define NoMangle
#endif
NoMangle int DLL_IMPORT_EXPORT foo(int,unsigned);
NoMangle int DLL_IMPORT_EXPORT foo(int Parm, unsigned Len)
{
...
}
LIBRARY TEST
DESCRIPTION 'Just testing some stuff'
CODE PRELOAD MOVEABLE DISCARDABLE
DATA PRELOAD MOVEABLE SINGLE
HEAPSIZE 1024
EXPORTS foo @1
Thanks again for the other advice, I'll see what I can do.

Try adding DLL_SOURCE_CODE as a preprocessor definition (in your project settings -> C/C++ -> Preprocessor). See if that fixes the problem.

Hi everybody,
is it possible to detect a mouseclick outside a modal dialog in a MDI?
I tried already:
Mouse-Click on MainFrame
KillFocus of the dialog (works only if i click outside the mainframe window(selection of another application)
But i need also to detect the mouse-click if i click outside the dialog and inside the mainframe
Does any one has an idea?
Big thanks in advance

You need to capture the mouse, then it will work.

I want to open an existing file without checking the file extension because this changes sometimes. In DOS (and windows) you can add an asterix (*) and all files with the same name are shown.
The file is opened with the FileCreate command:
<br />
sprintf(FileName,"%s%s.%s",readloc,ProdBest,ext);<br />
hFile = CreateFile(FileName,GENERIC_READ|GENERIC_WRITE,0,0,OPEN_EXISTING,0,0);
readloc is defined as: c:\\ProdIn\\, ext the file extension. these are defined in an INI file
ProdBest is the filename to be searched
if I define the ext as a txt file it works perfect, but if I change the extension to * I get error 123 (ERROR_INVALID_NAME)?

Yep - a * is invalid in a file path. You're creating a file, which means you need to specify the actual name, how can you use a wildcard to create a file ?

reading the doc I've found the FileOpen() function is not allowed anymore for a 32-bits processor, and the CreateFile() function should be used. So how do I overcome this problem? Do I have to check for every possible extension seperately?
|
|
|
|

You need to read his reply more carefully.
Using * (wildcard) is fine if you're searching for a file (eg FindFile), but no good if you're using a file - you're using a specific file, so you should give it an exact name.
Whether you're using FileOpen, CreateFile, fopen, CFile::Open, or MyStrangeFileAPI is beside the point.
Just think what would happen if more than one file was "found". Which should you use? Should it change? How psychic do you expect the OS to be?
Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

Enumerate all files with FindFirstFile() and FindNextFile() and filter out the one you want to open.
|
|
|
|
|
Functions that open files can only operate on one file at a time, thus wildcards are not valid in this context.

when im compiling the dll n using in my main.h...then it shows a message window with "LOADED" which means library is loaded...but it does not show any message window defined in the library entry function (DllMain's switch statement).....n it shows "TEST LOAD FAILED"...don't know why..please help me..i read an article on microsofts site for using dll n thats what im doing....link is
http://support.microsoft.com/kb/815065[^]
please help someone...
i also tried using
typedef void (*MYPROC)( );//like function pointer..n then using
MYPROC test;
its giving same outputs...first point that is making me mad is why the hell its not executing any of the MessageBOX( function in DllMain function...which is entry point...thanx...

Please use <pre> tags to surround code.
Are you loading the right DLL?
Have you used Dependency Walker on your DLL to make sure test function is exported?
