Ok Im New To C++ But Im Making A Code That Should Hopefuly Make Me Able To Write Into A Program's Memory

I Get These Error's

error C2059: syntax error : '.'
error C2447: '{' : missing function header (old-style formal list?)

My Code Is

.void WriteMem(DWORD MemOffset, DWORD DataPtr, DWORD dataLen) ;{
 DWORD OldProt;
 VirtualProtect((void*) MemOffset, dataLen, PAGE_EXECUTE_READWRITE, &OldProt);
 RtlMoveMemory((void*)  MemOffset, (const void*)  DataPtr, dataLen);
 VirtualProtect((void*) MemOffset, dataLen, OldProt, &OldProt);
}

If Anyone Can Help, It Would Be Great!

Most of the compiler errors in the thread come from two separate problem classes: stray characters/pasting artifacts, and missing platform headers. correctly identified the first: leading punctuation or quoting markers (for example a stray dot, >> or a semicolon placed before the function body) will make the compiler see invalid tokens and produce C2059 / C2447-type messages. Those tokens must be removed so the parser can see a valid function declaration followed by a block.

Once the stray tokens are fixed, the next set of errors (undeclared DWORD, C2065, and the eventual C1083 about the platform header) indicate the Windows typedefs and API declarations are not available to the compiler. The typedefs used in the original snippets are provided by the Windows platform headers; in portable code it’s also possible to use standard types (for example uint32_t/uintptr_t or plain pointer types) so a small test compiles without platform-specific headers.

The “cannot open include file” failure means either the Platform/Windows SDK isn’t installed or Visual Studio’s include paths aren’t pointing at the SDK. On Visual C++ 2005 the remedy is to install the Windows Platform SDK if it’s missing, and/or make sure the SDK’s Include folder is listed in the compiler’s include directories (project-level Additional Include Directories or the global VC++ Directories setting). If an Express/limited edition of the IDE is being used, the Platform SDK is often a separate download.

A few practical safety notes not yet emphasized in the thread: writing raw memory is inherently dangerous (privilege requirements, process integrity, alignment and pointer-size issues); prefer documented APIs for inter-process memory operations and use the correct pointer/integer types for addresses. For faster, actionable help in follow-ups, the most useful information to provide is: a minimal complete code example that reproduces the error, the exact compiler/IDE and OS, and the full compiler error output — that greatly reduces back-and-forth and makes advice from responders such as and more effective.

remove the period and the semicolon. neither belong there.

Did you even bother to read my post? I told you how to correct those errors. Re-read and pay more attention this time.

when I posted >> I was quoting your code -- its not meant for you to add >> to your code and compile it.

>>When I Say Im New To C++ I Mean Im New

If you are that new then you are attempting to do something that is wayyyyy over your head. Buy an Introduction to C or C++ book and start studying from page 1. Jumping into the middle like that will do little more than confuse you.

that takes time and money the ony thing i didnt understand was words...
period and semicolon

If you are not ready to spend time and money to educate yourself, why should we spend ours trying to educate you?

-.- I Cant Help A Habbit I Have

When you are adviced for your own good, be humble and try to correct it. Excuses and arrogance will not help you here. Arrogance will be tolerated once you start contributing to the community, but until that you are a newbie, so start acting like one.

Judging from your previous two posts, I see that you are way out of line and your attitude will be harmful to this community. Let this serve as a first warning.

Really? What words do you use? I have never heard them referred to by any other name.

> that takes time and money the ony thing i didnt understand was words...

You do know how to do an internet search right? Try typing "define: semicolon" into google

That's too bad.

Same Error's Just Fractionaly Diffrent

Heres My Code

>>.void WriteMem(DWORD MemOffset, DWORD DataPtr, DWORD dataLen) ;{
 DWORD OldProt;
 VirtualProtect((void*) MemOffset, dataLen, PAGE_EXECUTE_READWRITE, &OldProt);
 RtlMoveMemory((void*)  MemOffset, (const void*)  DataPtr, dataLen);
 VirtualProtect((void*) MemOffset, dataLen, OldProt, &OldProt);
}

Here's The Error's

Error C2059: syntax error : '>>'
Error C2447: '{' : missing function header (old-style formal list?)

Err... in a less hostile way.

To gunner64

Please try to understand that all the people out here help others voluntarily, there is as such no bonding on us. We take out our time to see that the newcomers dont face the difficulties which many of us have faced.

So by just showing a little bit of patience, effort in writing code and respect to the senior members you can get from this community much more than you expected.

Hope you understand that and by the way welcome to DaniWeb.

Is English your firse language, or a foreign language to you? If you took English in grade school (grades K - 8) your teacher probably introduced you to writing sentences, and you should have been taught what a period and semicolon look like. My 5-year-old grandaughter already knows that much:eek:

A period looks like these characters

...........

and a semicolon is this thing

;;;;;;;;;;;;;;;;;;;;;;;

now, just delete both those two characters from your original post and I said before.

>>And How Can A Habbit On Capital Letters Give Me A Warning...

Don't try that with the code you attempt to compile -- your compiler will complain bitterly if you capitalize when you should not.

Capatalizing every word is annoying, not cute, and just shows lack of intelligence. If you are under age 10 then you should be reading commic books or out doors playing softball.

Well, if you are going to ignore what we tell you is wrong with your program then I am going to stop trying to help you. You didn't change a thing. :mad:

DWORD as well as other win32 api functions are declared in windows.h, so just add that to the top of your program and it should compile

#include <windows.h>
// other code goes here
