Little bit of D3D hooking help

[Crash]

EDIT : I'm using ID3DXFont just so you know.

I have a menu and it works fine, for about 60 seconds... the text disappears/box disappears/crosshair disappears.

I'm thinking of a few ways to do this. They don't work too well because it takes about 10 seconds to re-hook which is inconvenient.

Here are the ways I've done so far :

1. Have a reporter variable(boolean) that sets it to true at the end of the hook func and then in an infinite loop in a thread it sets it to false and sets a timer variable to zero and the reporter variable to false again. If the reported variable is false in the infinite loop, the timer variable is set up one. After the timer variable is 100, it re-hooks because endscene wasn't drawing. The only problem is going ingame, it freezes when you hit start and endscene is frozen or something like that, then when it re-hooks the game ends. Here is what it looks like in code form:

//endscene func :
...{

//Drawing stuff here

report = true;
}

//Thread

...{

//Key checking in here

if(report){
    timer = 0;
    report = false;
} else {
    timer++;
    if(timer > 100){//This is the same thing I use at the start to hook without he RemoveDetour part
        RemoveDetour((PBYTE)myEndScene, (PBYTE)endscene);
        //Get endscene here
        oEndScene = (tEndScene)(DetourFunction((PBYTE)endscene, (PBYTE)myEndScene, 5));
        timer = 0;
    }
}

Sleep(10);

}

2 : Use the return value of DrawText() (it returns the height of the drawn text if it succeeds and returns 0 if it fails) to check if it fails at drawing. Once again, it fails when I go ingame because it isn't drawing.

3 : Re-hook :

if(GetModuleHandle("d3d9.dll") != NULL){
    //Hook stuffs
}

The problem with this ? No problem when going ingame
Sadly, it doesn't re-hook when the text disappears out/ingame because ES is drawing.

Anybody know how to get around this ? The ingame part is really annoying... (I will put your name in the credits if you can help me out)

Well, whenever I try hooking functions in like mid-execution, nothing ever happens. When I try opening the test environment and hook after everything is done loading, the function doesn't seem to get hooked and it won't draw anything... I think.

I'll test it later when I get on a real computer..

What game is this for anyway?

u could do all that, or u could just hook reset as well.

oReset = (tReset)(DetourFunction((PBYTE)reset, (PBYTE)myReset, 5));

make sure u reset ur font pointer to like so:

{
font->onLostDevice();
reset();
font->onResetDevice();
}

And btw try initializing ur font with the device inside the hooked function, that usually causes less bugs

PS: its nothing wrong with ur detour, its just that the device reset and ur font did not reset with it. u should never have to rehook a d3d function under normal conditions.

And bingo was his nameo.

And bingo was his nameo.

But I did that...

By reset() do you mean (device)->reset();

I'll try that and see if it works.

Here is my reset :

	p_font->OnLostDevice();
	p_line->OnLostDevice();

	pDevice->Reset(PresentationParams);//Going to try it

	p_font->OnResetDevice();
	p_line->OnResetDevice();

	return (HRESULT)oReset(pDevice, pPresentationParameters);

If you hooked reset, you can't use your device to call it. Use the one returned from the detour function.

Funny Dave. /yea

This is what I have now. I think this is what why meant.

p_font->OnLostDevice();
p_line->OnLostDevice();

HRESULT hreturn = oReset(pDevice, pPresentationParameters);

p_font->OnResetDevice();
p_line->OnResetDevice();

return hreturn;

You gotta be kidding me... it still doesn't work. The text disappears after 50 - 60 seconds...

EDIT : This is for Combat Arms, and I am hooking reset correctly because I alt+tabbed out and went back in and the message box that I put in the function popped up. The text still goes away sadly..

EDIT 2: Tried LPD3DXFONT instead and it went away, yet again.

do u have an msn, it would be easier if I could look @ the whole thing.
