ID3DXFont problem
Author
I am trying to use ID3DXFont. The code gets compiled but when I run the build it crashes instantly.
Here is the code I use
Can someone point me what`s wrong in this code?
One more thing the debugger traks down the problem to this line: 0xFFFFFFFF); //Color.

Crashing on the Draw call most probably means that g_font is a NULL pointer, i.e. font creation didn't succeed. What do you when font creation fails?
Am I missing something or does:
look a trifle fishy?
[source lang = "cpp"]//here you delete "g_font" if(g_font) { g_font->Release(); g_font=NULL; }//here you try and use "g_font" g_font->DrawText(NULL, //pSprite text, //pString -1, //Count &fontRect, //pRect DT_LEFT|DT_NOCLIP,//Format, 0xFFFFFFFF); //Color look a trifle fishy?

Nothing up to now. I just began working at this (I am trying to make a log file system)

I didn`t post my entire code. I release the interface in the GameShutDown function. GameShutDown is called when WinMain message loop is done.

Ok, I just added some error lockup code (HRESULT FAILED). D3DXCreateFont fails indeed. Do you know what might be the cause?
Edit: The debugging code:

The most common cause is an invalid device pointer. Are you sure the device is valid at the time you are passing it to D3DXCreateFont? Based on the log you posted it doesn't appear to have been initialized.
I have a similar problem (crashing instantly) though my crash isn't due to a null pointer (or atleast the logs don't show it). It looks to me like your problem is:
Try and fix that and see how it goes.
Edit: changed the color code, should work properly now.

CodeMaster Rapture: A Null pointer was the reason why my game crashed.
The problem is situated somewhere in the D3DXCreateFont(). Anyways, thanks for trying to help.

DrunkenHyena you are right. I`v placed my D3DXCreateFont function before my
D3D Initialization code. Thanks so much. Rating ++
