Hi all,
we al know the preffered load address of any proj is 0x00400000 and DLL is 0x10000000. now if the OS is unable to use this address it relocates the project.
now i have a need to use the Rva+Base address of all the methods available in a class within a project. One method is reading the map file but say if u don't have the address available so relocation takes place hence the safest way is to dynamicaly obtain it
hence i want to know is there any way of obtaining the base address or the load address of a process. if at all you feel this is not a viable solution then can i obtain the current address from the mangled names like ?show@disp@@QAEXXZ for a public method show belonging to class disp as per VC++ conventions.
undname just gives the resolved name but its of no use in callin a function. so can you people just help me out
for a better idea u can refer
1)Mangled Name
2)Private Access

You want the address of a function?
You can also get pointers to class methods. I have not used them so I'm not sure how they work.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

I think you didn't get my question correctly. I need the Load address of a process. So that i can calculate the Rva+Base address
please refer to the links i'd provided in my posts

The people as codeproject.com seems to have answered your question quite adequately. I see no point in rehashing something that was already posted over there.

secondly my private access is done whereby I did not perform any malicious activities
Still after this I really thank all of those who poured in suggestions and criticisms because both are complementary.
Thanks to all for there precious time spending on this thread. Will meet you guys in some other thread
