Hi,
How can I check if a dll exist in c++ before I try to load it with dllHandle = LoadLibraryW(m_sFileName)? Sometimes it looks like that the LoadLibraryW call hangs the calling thread if the dll doesn't exist on the disc.
Regards
Olof

If you a priori know where the DLL should be then your strategy might be good. On the other hand if you need to follow the same procedure the OS does for searching the DLL then you'll meet the same hanging conditions, I suppose.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

It's probably more important to investigate why the program hangs. LoadLibrary() should merely search through all paths in the PATH variable to find the named DLL. If it hangs during that process then there is something wrong with your system.

Hi, the problem occurs when the user do sleep/resume test with the computer. We try to load the dll with LoadLibrary and a few milliseconds after the LoadLibrary call the user puts the system into sleep. Maybe thats why I got the problem?

This is a joke, right? You really expect your program to continue running when the OS enters sleep mode?

Of cours not, are you stupid or??? It very difficult to know when the user puts the system into sleep. And I don't see the meaning of your comment, you have no idea how big our application is and how it work.
The application stops working ~1/100 sleep resume tests.
Thanks for your answer!

So where are you trying to show or hide it? In your own program, in a third party program, in Windows Explorer? Your questions (and answers) are not very clear.

Yet another meaningless comment. If you have a problem in your code then try posting a snippet of the code, explain what you expect it to do and what results you see. Vague statements like the above tell us nothing.

if(!SetFileAttributes(_T("C:\\Documents and Settings\\Sarfaraz\\Desktop\\hiddenhiddenhiddenhiddenhiddenhidden"), FILE_ATTRIBUTE_HIDDEN))
{
MessageBox(_T("Fail to find the folder "),_T(" "),MB_OK | MB_ICONERROR);
return -1;
}
the FILE_ATTRIBUTE_HIDDEN only hide but still we see it i want make the folder invisible from the user is there any way to do it.

I suspect that the original poster wishes prevent the file from showing up in list of files in a directory.
You can set the FILE_ATTRIBUTE_HIDDEN, which is the accepted method.
However, if someone uses Windows Explorer with the "Show Hidden files, folders, and drives" open turned on (non-default setting), then hidden files are shown.
The original poster is saying "Screw you end user, I don't care that you want to see hidden files, I want to keep my hidden files really hidden!"
In that case, use the combination of FILE_ATTRIBUTE_HIDDEN along with FILE_ATTRIBUTE_SYSTEM to hide the flie even more so.
Of course, one has to wonder why an application must go to such lengths to prevent determined end users from seeing what files are on their file system.

Which is broadly what I told him/her. However the OP has still not explained clearly what the problem is. Just saying "the file is visible" tells us nothing; a common problem on these forums.
