No Errors but wrong values on return?
-
I posted to you, but I think I put it on the wrong place, here is the post... Hi, I had make a lot of test and learn a lot thanks to your help, I also testing now how to work with those values. And I was wondering is there a way to return the HIWORD(pvi->dwFileVersionMS) and LOWORD(pvi->dwFileVersionMS) as a single long value instead of converting to a string and then back to a number, the reason I said that is because I have been testing with this code below... // wsprintf(BUFF,("%u.%u"),HIWORD(pvi->dwProductVersionMS), LOWORD(pvi->dwProductVersionMS)); // double RTVAL=atof(BUFF); // if(RTVAL==6.1) MessageBox(hwnd,"It is 6.1","atof return",MB_OK); // Tested OK RTVAL was 6.1 // return RTVA; Thanks
Why are you converting a string to a double just to do a simple comparison? Use a string comparer (strcmp) like:
if(strcmp(BUFF, "6.1") == 0) MessageBox(hwnd,"It is 6.1","version",MB_OK); // Tested OK RTVAL was 6.1
Or even simpler
if (HIWORD(pvi->dwProductVersionMS) == 6 && LOWORD(pvi->dwProductVersionMS) == 1)
MessageBox ... -

MessageBox ...No my friend those are just experimenting I discover that I could do that, but the main point using the right fields of the struct and the formatting YOU teach me a lot with that. The question was is there is way to combine both Hiword & Loword and return it as a single long / decimal number, take a look to the idea below. long THEVERSION { Source code here like before return THEVERSIO; // This will be a long or double with the value of 6.1 or whatever. } That function will return 6.1 ( one single number ) is this possible? and thanks again.

No, it would be difficult, since a LONG type would have to hold the number as 61, or even 611 if the low order value was 11. Each of the four fields are independent values which represent the Major, Minor, Revision and Build numbers of the version. It does not make sense to try and combine them into a single value.

I had see many examples on getting the windows version, this is not the case. Even Microsoft on on a web page show a funtion that does not work as it shows. Thank
