Speed optimization question: Having this code: F1_bak = F1_bak+An+Mn[0]; // add the already computed Mn[0] value unsigned int lr_val1_bak = leftrotate(F1_bak, s[0]); unsigned int Ban1Test = Ban[0]+lr_val1_bak; if (Ban[1]!=Ban1Test) { //printf("Invalid Ban[1] value!!!!\n"); goto StartOfSearch; } versus second one: unsigned int Ban1Test = Ban[0]+leftrotate((F1_bak+An+Mn[0]), s[0]); if (Ban[1]!=Ban1Test) { //printf("Invalid Ban[1] value!!!!\n"); goto StartOfSearch; } It happens that the first one is faster, there is more code to it and the difference is of 10 seconds! Can someone explain why?

Could anyone please shed some light on me about the process of creating an exe (outputting a compiled exe) from another exe? Like the loader/patcher programs, you put the name of the program you want to patch, put addresses and bytes, then click some "create patcher" button and the patcher-creator program outputs a patch.exe for you. Or like the keylogger or rat programs, after selecting desired settings, you click some "create server" button, and it outputs a server.exe for you. I am somewhat lost about how this process is done, tried googling but couldn't find any source to learn (maybe I don't even know how to search on this topic). For starter, I want to make an …

Hi guys, today I check some of my windows sockets codes and wanted to update & optimze it a little writing some clean code without to be messy to have also a better view on it.Now I came to the hostent struct which returns a pointer to this struct after calling gethostbyname / gethostbyaddr.Now in the MSDN description I can read that this struct is only used once for each call to this function and getting overwritten by another call.Now they say I should copy the struct into other buffer. So does it mean I dont need to copy it into extra buffer if I call the function from diffrent created threads?Just if I use same thread = copy to buffer?So normaly I ca…

Getting most significant bits...

Mainly for anyone using asm and interested in custom controls or adding more functionality to their projects, I recently began work in porting over, adapting and adding to DrawHTML code from Ukkie9: https://www.codeproject.com/Articles/7936/DrawHTML I created two functions: DrawHTMLCODE and DrawBBCODE that processes html or bbcode tags in a string and adjusts the text and font style accordingly and outputs the result as per DrawText or DrawTextEx win32 api functions, but with the added enhancements. So far some tags are supported, not all. Mainly ones that are more common in use, or made sense to include. Anyhow I have put the code on github for anyone to u…
