  DWORD dwRead =0;
 
  



  while(InternetReadFile(handle1, Buffer, sizeof(Buffer), &dwRead) == TRUE)
  {
    if ( dwRead == 0) 
      break;
    DWORD dwWrite = 0;
	progress2 += dwRead;

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

Solution 1

use the PostMessage API. Post a user defined message to your window/dialog. There you handle it and set the value.

Maybe you should use PostThreadMessage somehow like that:

If you want to comment on a post it is best to use the "Have a Question or Comment?" link next to a post rather than posting a solution. As you can see - you will just get downvotes.
