    well, lets try this this! have you ever tried opening an exe file using 7zip?
    when you right click on an *.exe and choose extract files!, you will get a folder containing all of the sessions that is included in an exe file , including .rdada , .idata, .text,.rsrc,and .bss and etc
    so let me ask , how can i do the same thing ? and have them in an folder!?

    why not to take a source code of 7zip and take a look?
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    What do you ACTUALLY want to do?

    The executable format of MS's files is documented, so you can read them just like any other binary file.

    Or you can use tools like "strings" to read strings from the file, perhaps?

    ive already gone after it , all of Microsoft executable files utilize a format called "PE"(portable executable) , i read an article concerning that which i found at wiki, well the PE has a structure
    http://upload.wikimedia.org/wikibook...vEngPEFile.JPG
    well , i have no idea which part contains the texts used in .exe, so just by chance i used 7zip and i noticed that there is an .rdata in any exe file that contains strings used in the file(.exe) so i managed to find a way to access that .rdata instead of messing with the whole PE strcuture and get the job more complecated!

    everytime i search about that .rdata! i bump into nonsens!


    and about looking at 7zip source code, well i m just a begginer and dont know much about C++ yet! so i may easily get confused ! anyway im planning to have look too .

    .rdata is no different from any other section of code/data in the PE file - it's the name of one of the segments, just like .data, .bss, .text, etc.

    I still don't understand what your question is? [Your local image won't show because my computer can't read the C: drive on yours - maybe a better idea to upload it rather than link to it?]

    my questions are "how can i read the contents of rdata!, where is it located ? and how can i access it? or at least divide an executable file to these sectios! just like 7zip does!

    and about the picture . i use fire fox and ScarpBook addon! , i thoght it retains the links! and doesnt give me the local address !

    Try this page:

    It may not do exactly what you want, but it's close, I think.

    by the way in the picture i posted, there is no sign of these sections! ?
    actually all we are dealing is Dos Headers (MZ stuff, and the text that says it runs under dos or it doesnt! ),PE signature!,Coff Header, Optional headers and section table plus mapped sections!
    so this is the whole PE structure! i cant see any .rdata session!
    it must be somewhere inside one of the other sections! ? (which one? i have no idea!)
    and how to get that sections of these sections . ? still i have no idea! that why i asked for your help
