    Hi guys, does anyone know how to create a own memory viewer what does show memory similar as HxD?Offset / Hex etc you know. So normaly I would open any choosen process and read entire memory from 0 - F using VirtualQuery and then I need to show it anyhow.Not sure whether I should use a edit control or anything else.Next question would be how to show it with offset addresses / hex / ASCII and how to update the memory if it does change.Hhmmm.Has someone any ideas / hints how to handle that?Just wanna create a memory viewer + some search function only. Thank you

    In the PE file format, there is the DOS_HEADER and then right after that, there is a section called doscode which is by default 64 zero bytes. However, sometimes it is filled with an arbitrary number of bytes. Some PE files have a lot of bytes here, others don't. How can I calculate the number of bytes that doscode will be? There doesn't seem to be any field in the DOS header which specifies this. Thanks.

    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?
