Re: [Dev-C++] More Version checking

[Bruno B. <bbe...@cl...>]

Hi !

Here is a sample code for version checking:

#include <stdio.h>
#include <windows.h>
#include <winreg.h>
#define BufferSize 255

void NoAR()
{
     printf("Acrobat Reader is not installed\n");
     exit();
}

int main(int argc, char *argv[])
{
  PHKEY hKey, hKeyAdobe,hKeyAcrobatR;
  LONG Result;
  WORD iSubKey=0;
  char Buffer[BufferSize];
  /* check for the key "software" */
  Result=RegOpenKeyEx(HKEY_LOCAL_MACHINE,"software",0,KEY_READ,&hKey);
  /* all right then look for the "Adobe" subkey */
  if (Result==ERROR_SUCCESS)
  {
   Result=RegOpenKeyEx(hKey,"Adobe",0,KEY_READ,&hKeyAdobe);
   if (Result!=ERROR_SUCCESS) NoAR();
   Result=RegOpenKeyEx(hKeyAdobe,"Acrobat Reader",0,KEY_READ,&hKeyAcrobatR);
   if (Result!=ERROR_SUCCESS) NoAR();
   /*print all the subkeys */
   while(Result!=ERROR_NO_MORE_ITEMS)
   {
     Result=RegEnumKey(hKeyAcrobatR,iSubKey, Buffer, BufferSize);
     printf("%s\n", Buffer);
     iSubKey++;
   };
  }
  else printf("No Software key\n");
  return 0;
}
