I am trying to implement self integrity check in MFC exe.

Ref : -
Tamper Aware and Self Healing Code

I dumped text section.

C++

    ofstream myfile;
myfile.open ("textsec.bin");
myfile.write((const char*)pCodeStart,dwCodeSize);
myfile.close();

Every time its different so hash for it is also different. Please Help.

If we implement Tamper Aware and Self Healing Code in console application it works fine . But if we try to implement it in MFC application we cant. because hash of text i.e. code section from memory we calculate is different every time. I want to know why this happens can we stop this ?
