It's legal - a tag name is not a type name. Struct, union and enum tag names share one namespace, while type names all share a different namespace. This means that typenames can be the same as tag names.
That means that your example is legal, but the following isn't, as the three tag names (for the struct, union and enum) are all the same:
typedef struct _VECTOR {} _VECTOR;
union _VECTOR {};
enum _VECTOR {};

yeah, I got the definition,
owe you one.

Hi,
Your code is valid C code, whether it is legal I can not say.
Normal C compilers will accept it; the odd one that would not, would be wrong.

BTW: The executable has some dependecies. It may find them in the installation path.
What do you want 'to resolve' (i.e. It works at should be, in my opinion...)?

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.

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.

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..
God bless you...

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
