Determine whether a program is 64-bit or 32-bit

1. Use CodeDetermine if (intptr. size = 4) {// 32-bit} else if (intptr. size = 8) {// 64-bit

}

2. use the code to identify other processes that are running http://stackoverflow.com/questions/1953377/how-to-know-a-process-is-32-bit-or-64-bit-programmatically 3. no code to determine any EXE, see the second reply http://blogs.technet.com/ B /windowshpc/archive/2009/03/27/how-to-tell-if-a-exe-file-is-a-32-bit-or-64-bit-application-using-dumpbin.aspx if you have a hex editor program, just open your file with it and shortly after the Standard Header intro stuff (like "This program cannot be run in DOS mode... ") You will see either" pe .. L "(HEX Code: 50451_4c) = 32 bitor

"Pe .. d Pipeline" (HEX Code: 504500006486) = 64 bit

In fact, a common text editor (such as NotePad) can be used to search for the PE and the following results (64-bit) (32-bit) will be published through wiz.
