Problem while using "LoadLibrary(...)" 1

[firelex]

Hello, all!
The situation is:
I have a dll. Now I want to attach it to a process. But

     LoadLibrary("MyDll.dll")

Always returns

NULL

!
First I thought the path is wrong, but

  WIN32_FIND_DATA FileData;
  HANDLE hFile;	
  hFile = FindFirstFile(path, &FileData);
  if (hFile != INVALID_HANDLE_VALUE) {
	TRACE (&quot;\nFile <%s> exists!!!\n&quot;,path);
  } else {
	TRACE (&quot;\nFile <%s> doesn't exist\n&quot;,path);
  }

Always says that file exists!

Any ideas?

use GetLastError/FormatError to see what is up.

GetLastError

says the error is 126 -> specified module cannot be found!

In this case
1. specify full path to your dll:
LoadLibrary("disk:\\directories\\MyDll.dll&quot
or
2. put your dll in some system directlry
or
3. Add to environment variable Path the directory where is situated your dll.

I've tried the full path and PATH-variable also - no luck.
It is like WooDoo: by my dll

LoadLibrary

always returns error #126, but as I tried another dll from windows\system32 it worked...
What does it mean

ERROR_MOD_NOT_FOUND

, if it is given back by

LoadLibrary

? Is it like "file not found" or something else?

Look in MSDN what does ERROR_MOD_NOT_FOUND mean.

Hi,

it just could be that your DLL is dependant of some other module which is actually not found by the system. You might want to check that (using Dependency Walker)

Hope this helps,
