newbie problem with RegSetValueEx

w332 · #1 16-Jul-2004, 15:43

hello, im trying to alter this piece of code so i can add it to my program,
the code works, the "aplication" is added to the registry and boot, but
the problem is that the path in the reg. entry goes to the curent directory
of where the exe is in. i understand that this is cuz of the char *szBuf;
but even though i have searched google for a long time i dont understand
how i can change this, what i want to do is just add a path to my program
ex: c:\program files\my program (excuse me for not using // coments, since i dont understand the whole code im not cabable of doing this)
help very much apreciated..

CPP / C++ / C Code:

HKEY hkey;
char *szBuf;
TCHAR buff[255];
DWORD bufflLen = 255;
LPTSTR dirBuff = buff;

GetCurrentDirectory(buffLen, dirBuff);

buffLen = strlen(dirBuff);

if(buffLen > 3)
      szBuf = strcat(dirBuff, "\\myprogram.exe");
else
      szBuf = strcat(dirBuff, "myprogram.exe");

RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Software\\Microsoft\\Windows\\Currentversion\\Run", 0, KEY_SET_VALUE, &hkey);
RegSetValueEx (hkey, "myprogram", 0, REG_SZ (LPBYTE) szBuf, strlen(szBuf) + 1);
RegCloseKey(hkey);

No guarantees, because I don't like messing with the registry, but why not try something like:

CPP / C++ / C Code:

HKEY hkey;
char *szBuf;
TCHAR buff[255];
DWORD bufflLen = 255;
LPTSTR dirBuff = buff;

//GetCurrentDirectory(buffLen, dirBuff); - Instead of this do:
strcpy(dirBuff,"c:\\program files");  //Or whatever directory you wanted.

buffLen = strlen(dirBuff);

if(buffLen > 3)
      szBuf = strcat(dirBuff, "\\myprogram.exe");
else
      szBuf = strcat(dirBuff, "myprogram.exe");

RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Software\\Microsoft\\Windows\\Currentversion\\Run", 0, KEY_SET_VALUE, &hkey);
RegSetValueEx (hkey, "myprogram", 0, REG_SZ (LPBYTE) szBuf, strlen(szBuf) + 1);
RegCloseKey(hkey);

Like I said, don't hold me responsible for any of your pets dying from running the above code.
