Hello DaniWeb. ;)

I have a problem with char->tchar conversion, that i cant seem to solve. I want to launch another program, anh the relative path to that program is fetched from MYSQL.

updateBox = CreateDialog(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_DIALOG2), hWnd, updateDiag);
hThread = (HANDLE)_beginthreadex(NULL, 0, Blah::Start, NULL, NULL, NULL);
_stprintf(patcherLoc, _T("%s/Patcher %s.exe"), UPDATE_DIR, row[2]);
strcpy(patcherUrl, row[3]);

I have tried like anything i could find on google, fx MultiByteToWideChar() - i even gone as far as to write it to a char, write the char to a file, read, and then in tchar format, from the file.

The TCHAR just contains some chineese symbols, and the only readable being "/Patcher" and ".exe".

It really just needs to be LPCTSTR-readable, so my ShellExecute will work.

MessageBox(hWnd, patcherLoc, _T("Error"), MB_OK | MB_ICONEXCLAMATION);
ShellExecute(NULL, NULL, patcherLoc, NULL, NULL, SW_SHOWNORMAL);

I use the messagebox to monitor how my TCHAR is doing.


I hope anyone can help me solve this problem.

Cheers :)

1) Are you compiling for UNICODE?

2) what compiler

3) how is UPDATE_DIR declared

4) note that %s and %S are not the same thing. See this

Try

// wcstombs(char *mbstr,const wchar_t *wcstr, size_t count)
//
...
CHAR *mbBuf= new CHAR[100];
TCHAR *wcBuf=_T("hello");
#ifdef _UNICODE
wcstombs(mbBuf,wcBuf,100);
#else
strcpy(mbBuf,wcBuf);
#endif
...
delete[]mbBuf;
...

wcstombs, strcpy are deprecated..
More secure versions are available..
Take care..

1) I am compiling UNICODE.
2) VC++
3) #define UPDATE_DIR "updateContent"
4) I'll read that, thanks.

Try

// wcstombs(char *mbstr,const wchar_t *wcstr, size_t count)
//
...
CHAR *mbBuf= new CHAR[100];
TCHAR *wcBuf=_T("hello");
#ifdef _UNICODE
wcstombs(mbBuf,wcBuf,100);
#else
strcpy(mbBuf,wcBuf);
#endif
...
delete[]mbBuf;

Thank you for the answer.
- But I cant figure out where, in this code, my own stuff is to be placed.

Thank you for the answer.

Well..
Why dont you try it first..
There is another example for you..

/* 
 * mbstowcs(wchar_t *wcString,char *mbString,size_t nCount);
 */
... 
TCHAR *wcBuf=new TCHAR[100];
CHAR *mbBuf="MB STRING";
#ifdef _UNICODE
mbstowcs(wcBuf,mbBuf,100);
#else
strcpy(wcBuf,mbBuf);
#endif
...
delete[]wcBuf;
...
