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[^].

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.

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 *.*?

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);
}
}

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

Thanks a lot my friend i try it out and update with u the results..

Directly take the output from findFileData.cFileName.
The problem exists in your convertWCharArrayToString().
std::cout <<fileNumber <<":" <<findFileData.cFileName <<std::endl;
|
|
|
|
|
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

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.

I want to hook a mouse events of a specified window. So, i install a WH_MOUSE hook callback procedure for that thread.
If i didn't hook that message, the thread would show a pop menu when it received a right button message.
After i hooked that thread, windows would call my callback procedure when such event occurred, but the original window's message handler would be called, too. But i want to hold such message to make the original window will not receive such message. I use global hooks but check the process id like:
LRESULT CALLBACK MouseHookProcedure(int nCode, WPARAM wParam, LPARAM lParam)
{
if(0 > nCode)
return CallNextHookEx(g_hPreviousMouseHook, nCode, wParam, lParam);
MOUSEHOOKSTRUCT *pMouseHooksStruct = (MOUSEHOOKSTRUCT *) lParam;
DWORD process_id;
GetWindowThreadProcessId(pMouseHooksStruct->hwnd,&process_id);
if(process_id==target_process_id){
.... my process
return 1;
}
return CallNextHookEx(g_hPreviousMouseHook, nCode, wParam, lParam);
}
that, target_process_id is stored in the shared segment block, im sure its ok.
How to fix such a problem?
Regards.

what happens if you dont call CallNextHookEx in the return statement ? (ie remove the CallNextHookEx and return [something else])
... it occurs to me that is what is propagating the message to the next handler.
'g'
|
|
|
|
|
you means the last? if the message is in the window handle i want to handle, the last CallNextHookEx will not be called.
|
|
|
|
|
Are you sure your hook is being called?

of courese im sure. i place a messagebox at the if block, the messagebox will display there.
