I gave you a link to the documentation, you need to go and study it to decide which items you are interested in.

Use the best guess

may be this help u... Smile | :)

u may have dialog class like,

C++

CPageSetupDialog abc;
//Conding to set values.
abc.papersize = 10;
abc.sorce = "ACC";
abc.margin = 44;
//ETC.
//And then modal it..Like,
if(abc.DoModal() == IKOK)
{
//Success;
}else
{
//Fail..
}

gives error

Read the docs, PLEASE!

abc.m_psd.ptPaperSize = 10;
abc.m_psd.rtMargin = 44;

I need to debug a program for which I do not have the source code.

I want to place a breakpoint at the CreateFile() Win32 API.

I have told Visual Studio to load the symbols for KernelBase.dll and Kernel32.dll .

Now how can I tell the Disassembly View to take me to the location of CreateFile()?

Thanks in advance.

Visual Studio is not the right tool for reverse engineering. Use IDA Pro or OllyDbg. IDA Pro is damn expensive while OllyDbg is free. A lot of reverse engineering guys use these.

Thanks, I'll look into both of those.

I'd use WinDing, set up a symbol server and place a breakpoint directly on CreateFile. No need for disassembling.

Is WingDing a tool? My Google foo is not working.

WinDbg. Look up "debugging tools for windows".

Sorry about the "WingDing". Auto correction got me.

Using WinDbg try these two commands:
bp kernel32!CreateFileA
bp kernel32!CreateFileW

Thanks, I didn't realize it was so easy with WinDbg.

Take a look at Microsofts public symbol server. You can download symbols for all their code from it, and set breakpoints and so on.

You can speciyf these sylbols in VS and when it tries to load downloads them automatically. I use windbg though so I cant help you much more than that, and I work in the kernel, but if you choose to do the same this is a usefull command:

bp nt!ntcreatefile "dt nt!_UNICODE_STRING poi(poi(@esp+0xc)+0x8)"

It sets a break point on createfile (this is what CreateFile maps to in the kernel) and displays the file being opened (This is 32 bit, if it was 64 the parameter would be in a register not on the stack).

SO any user mode acces to creatfile you can break on and have a wander arond the stack and see whats doing what.

--edit--

Or as the poster above says, set the bp in the usermode dll.

I can deffinitely recomend using windbg, it is a hell of a debugger, everyone in microsoft uses it, VS is a toy in comparison.

==============================

Nothing to say.

Yes, but I have shyed away from it due to its complexity. I guess I'm just a dumb "user" at heart.

Maybe this will encourage me to try it. Smile | :)

It is complex and command driven rather than UI driven, but what a command set! It can do amazing things.

I use the IDE's debugger when I can cause it's convenient and easy to use, but the second things get even a little complex I break out WinDbg.
