Hi All.

I have some simple problem.
In my program, I use

HANDLE FindFirstFile(
LPCTSTR lpFileName,
LPWIN32_FIND_DATA lpFindFileData
);

I Have problem if I wont to find all files in folder.

I cant write:

FindFirstFile("C:\\My File\\*",&FileData);

or

FindFirsttFile("C:\\My File\\*.*",&FileData);

Thanks for any help.

I think you need to read the documentation[^] once again.

The first parameter is a handle, not a string. This handle is retrieved by calling FindFirstFile.

Well, then it would be nice that you explain what you mean by "I can't write". This is not clear at all. What's happening ? Do you have a compilation error ? A linker error ? Or what ?
(And of course, if the compiler give an error, then supply it to us also).

Now not compile error, somting else.

In program I use

hSearch = FindFirstFile("C:\\My Files\\*.*",&FileData);

if(hSearch != INVALID_HANDLE_VALUE)
{
. . .
. . .
// pFileNameOld = L"C:\\My Files\\" + FileData.cFileName

//in this
_wrename(pFileNameOld,pFileName);
}

wen I try to rename file program stop work and thets it.

in "Watch1" I see thet FileData.cFileName is equal to ".", why?

Strange, are you sure it is ".".
Use FindClose to close file handle brefore renaming it.Check return value of _wrename for any possible arrors.

There are two directories in every folder named "." and "..", They are usually hidden system directories that allow navigation. You cannot do anything with them, so in your code, when you find them, skip them.

"." means "current directory", which is a sub directory as far as the filesystem is concerned
Likewise for ".." (parent directory)

So you need to do some extra checking to see if you're dealing with a file or a folder

I need to find all files in given folder,

Sorry for that.

See what GetLastError returns. See the documentation for further details.
