Best answer is FindFirstFile/FindNextFile and other way that its not good using of DlgDirList Function.

Since you are not using VC++ compiler, i'm sticking to pure windows apis. You could use FindFirstFile() and FindNextFile(). Check out this sample[^]. Regards, Jijo.

JiJO raj, thanks ya but its still showing 27 C:\Documents and Settings\Thilek\Desktop\2nd_trial\god\main.cpp cannot convert `const WCHAR*' to `const CHAR*' for argument `1' to `void* FindFirstFileA(const CHAR*, _WIN32_FIND_DATAA*)' i running it on DevC++ since when i run it in VC++ express 2005 many header files missing in its library.... Any suggestions ???

This is a Unicode issue. You'll need to use wcout.

NOW I CAN RUN IT USING VC++ PROFF 2005 NO PROBLEM :) .. Below is the code i use : 1.#include <windows.h> 2.#include <stdio.h> 3.#include <iostream> 4.#include <string> 5.#include <sstream> 6. 7. 8. 9.std::string convertWCharArrayToString(const WCHAR * const wcharArray) { 10. std::stringstream ss; 11. 12. int i = 0; 13. char c = (char) wcharArray[i]; 14. while(c != '\0') { 15. ss <<c; 16. i++; 17. c = (char) wcharArray[i]; 18. } 19. 20. std::string convert = ss.str(); 21. return convert; 22.} 23. 24.int main() 25.{ 26. WIN32_FIND_DATA findFileData; 27. HANDLE hFind = FindFirstFile((LPCWSTR)"*", &findFileData); 28. 29. if(hFind == INVALID_HANDLE_VALUE) { 30. std::cout <<"No files found." <<std::endl; 31. } else { 32. std::cout <<"Files found." <<std::endl; 33. } 34. 35. int fileNumber = 0; 36. std::cout <<fileNumber <<":" <<convertWCharArrayToString(findFileData.cFileName) <<std::endl; 37. while(FindNextFile(hFind, &findFileData)) { 38. fileNumber++; 39. std::cout <<fileNumber <<":" <<convertWCharArrayToString(findFileData.cFileName) <<std::endl; 40. } 41. 42. FindClose(hFind); 43. 44. char a; 45. std::cin>> a; 46. return 0; 47.} But when i change HANDLE hFind = FindFirstFile((LPCWSTR)"*", &findFileData); to HANDLE hFind = FindFirstFile((LPCWSTR)"C:\*", &findFileData); its showing no file found and some funny symbols... but i wanted it to show entire list of files in a directory if i choose C:\ or D:\ and so on.. Can u guys help me plz... :)

Use two backslashes within string literals. Why are you using convertWCharArrayToString()?

Still the same i tried using HANDLE hFind = FindFirstFile((LPCWSTR)"C:\\*", &findFileData); i even tried with "C://*" "C://" "C:\\" still showing no files found and some funny symbols... if i ever change it from "*" to anything this was happen.. hmmm... i am blur now... Help me plz... Thanks...

What if you used *.*?

How are you verifying this?

well it jus show the folder name where is the c++ files are located if i use "." ... its not moving out of the folder....

Directly take the output from findFileData.cFileName. The problem exists in your convertWCharArrayToString().

std::cout <<fileNumber <<":" <<findFileData.cFileName <<std::endl;

This makes little, if any, sense. Perhaps you are not understanding relative vs. absolute paths. For example, if you specified "*.*", then ".\\*.*" is implied and the files in the current working directory (CWD) will be listed. If you specified "..\\*.*", then the files in the CWD's parent folder will be listed. If you specified "c:\\*.*", then the files in the root folder will be listed. Consider:

void main( void )
{
WIN32_FIND_DATA findFileData;

HANDLE hFind = FindFirstFile(\_T("\*.\*"), &findFileData);
if (hFind != INVALID\_HANDLE\_VALUE)
{
    BOOL bFound = true;
    int fileNumber = 0;
 
    while (bFound)
    {
        fileNumber++;
        wcout << fileNumber << \_T(":") << findFileData.cFileName << endl;

        bFound = FindNextFile(hFind, &findFileData);
    }

    FindClose(hFind);
}

}

well still the same.. if i put the exe file in C:/ and run it it shows the files and folders in C:/ but it does not going in further into the folders and get the file list.... The program i been working have to get the entire files in the subfolders.. since i am creating a anti-worm system... thanks :)

Thilek

but is there anyway if i type in C:/ or D:/ it will show files in the directory including the files in sub folders ???

Yes. The easiest solution is via a recursive function call. Examples are plentiful on the Web and here at CP.

Where do you have problem exactly?FindFirstFile is easy to use?

You have to recursively call and iterate each Folders from the output if findFileData.dwFileAttributes is FILE_ATTRIBUTE_DIRECTORY. Try that.
