Hardware Bkpoint

[Rumour]

How can set hardware bkpoint by asm code? (masm)

Google find only in C:

//Set your context flags like this
this->cx.ContextFlags = CONTEXT_FULL | CONTEXT_DEBUG_REGISTERS;//Creates a Hardware Break on Execute Breakpoint
bool DebugEngine::SetBreakOnExecute(DWORD addr)
{	if (!this->UpdateContext())
	{
		return false;
	}
	cx.Dr0 = addr; // set Bp addr
	cx.Dr7 = 0x1; //activate it	if(!this->SetContext())
	{
		return false;
	}	return true;
}

But I need in masm, google not find.

I ask in ARTeam too. No answer.

This perhaps somebody here have know how?

Thank for all tip.

omfg please leave asm if you dont know how to use it. seems its not for you.

its pure winapi not some ****ty mfc so what you want more, just write code with invoke.

go to msdn.com and read about context structure and those winapi's that are in other functions like SetContext

or is it too hard to write

mov cx.dr0,addr

and change cx to some other name due its asm, and cx is reg so is reserved word

so proper will be

mov context.dr0,addr

invoke SetThreadContext,pinfo.hThread,o context

in my unsafecast you have in masm how to use context and getthreadcontext so change g to s and you have set
