All file formats support signing differently. Word has a different way, PDF has a different way. If you are going to deal with Word and PDF then you should look at both the Word API's and the A ...Show All

• Smart Device Development Memory problem using GetAdaptersInfo?

  Hi, I'm programming on a Samsung i730 with evc4. I've been monitoring memory usage when calling GetAdaptersInfo and I've noticed that it will randomly bump up the memory anywhere between 0-8192 b reguardless of the results I get. I do not know how to recover this memory. Since my program will be calling this function often, it will slowly consume all the memory. Does anyone know why this might happen Here is some code: IP_ADAPTER_INFO* aInfo= 0; ULONG size = 0; DWORD result = GetAdaptersInfo(aInfo, &size); ... delete [] aInfo; after this, the memory use can go up by any of 0, 4096, or 8192 bytes (bits ) Any help is much a ...Show All
