Hey Guys

I just about had it

I have been working on a getting my signed files to be verified for ages now but i keep getting an error message from the cryptverifydetachedmessagesignature. The error message is "error operation completed sucessfully" so you can see my fustration. obviously its not completing succesfully though because otherwise it would return TRUE. So i am completly stuck the bit that pisses me of most though is this was working then i decided to do it a different way rather then reading each bit in from a file and this didn't work so i went back to what i did before and it just won't work any help would be greatly appreciated.

Cheers
Peter

I got into a mess like that. I just put in a line like

verify();

after EVERY api call I made. I also made sure that I didn't do tricky stuff like use api calls as aguments. No all-in-one-line stuff.

I found that things I thought were working were not. Some functions return -1, 0 , +1 or special codes.
So test each call.

with a global FILE * - 

FILE *complain;
complain = fopen("mycomplaints","w");

void verify(){
  char Buffer[200];
  FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM, NULL,     GetLastError(), LANG_NEUTRAL, Buffer, 200, 0L);
  fprintf(complain,"%s\n",Buffer);
}

For what it's worth - I got this from allapi.net sample code on how to use the crypto calls suite. It's not in C it's written in VB, but it may help you.
