Hey, ive been trying to read in the name of the first file in a certain folder but im not sure if the folder is relative or a full path.. AND im not sure on the syntax your supposed to use. here is my current code, hFind is calling an invalid handle value and it gives me a load of IIIII's with squigles over them.

LPCTSTR myDir = "books\\*.ebr";doesnt throw an error but i stil cant get foundFile to show something understandable still "ÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌÌ" .
if (hFind == INVALID_HANDLE_VALUE) { ::MessageBox(0, FindData.cFileName, 0, 0);} This is true when you don't find any matches. You should be checking for a valid handle.

Allright done that, doesnt throw an error but still getting the same rubbish, is there anything else im doing wrong?
This example will print out every file/subdirectory from the current directory.
#define WIN32_LEAN_AND_MEAN#include <windows.h>#include <iostream>int main (int argc, char *argv[]){ WIN32_FIND_DATA finddata; memset (&finddata, 0, sizeof(finddata)); const LPCSTR pattern = "*.*"; HANDLE hmatch = FindFirstFile (pattern, &finddata); if (hmatch != INVALID_HANDLE_VALUE) { // Loop through every match // (will output both files and directories) do { std::cout << finddata.cFileName << std::endl; } while (FindNextFile (hmatch, &finddata)); } else { std::cout << "No match for pattern '" << pattern << "'." << std::endl; } FindClose (hmatch); return 0;}

The thing is i dont want to just write out the files in the directory, i want to place it into a LPCSTR/char*/string variable so i can choose one and using another function load the text in those files accordingly. So i need a way to save the name of a text file into a variable, and doing something like:
LPCSTR foundFile;
foundFile = finddata.cFileName;
doesnt work, got any idea of a solution?
LPCSTR foundFile;
foundFile = finddata.cFileName;
doesnt work, got any idea of a solution?
Well, look at the line where all of the printing occurs. Change the printing to something that will store that value into a string. I believe this:
std::string filename(finddata.cFileName);
will work, but I haven't tested it.
edit-I didn't see the part where you tried:
LPCSTR foundFile;
foundFile = finddata.cFileName;
edit2-What do you mean 'it didn't work'? Was there a compiler error? The following code Does work on my computer:
std::string filename(finddata.cFileName);
will work, but I haven't tested it.
