   instant help required  LPD3DXFONT
  i have a problem.i am making a program in which texts (that are written by LPD3DXFONT ) are moving 5 pixels to right or left (24 frame per second what makes 120 pixel in a second).   My Texts were flickering.I couldn't realize the reason of this first.Therefore i have tried the correct the correct codes:) without touching the  matter.But at last i have realized that cause of the flickering is LPD3DXFONT->DrawText(..) function draws itself to the screen (primary buffer-monitor) it is not drawing texts to backbuffer.isn't it?  So in my programDevice->BeginScene()..//MyGui widgets->DrawYourself(..) ====>These are drawing themselves to backbufferMyText->DrawYourself(..)   ==> this gui draws its texture to backbuffer  //but the text on it is written to frontbuffer so   //flickering occurs because there is no double_bufferinDevice->EndScene();Device->Present() ;   Now my question is İs there a way to force d3dxfont for drawing its texts on backbuffer or on any texture/surface..   Plz helpPS : if you ask how did you realize d3dxfont->DrawTExt(..) draws itself to frontbuffer? i did this.. ( an idiot double buffering:) )Device->BeginScene()..   //START FİRST DRAWİNG//MyGui widgets->DrawYourself(..) ====>These are drawing themselves to backbufferMyText->DrawYourself(..)   ==> Device->EndScene();Device->Present() ;static int cntr1=0;if(++cntr1==2){   cntr1=0;    Device->BeginScene()..   //START SECOND DRAWİNGDevice->Clear( clear back buffer with black color );Device->EndScene();Device->Present() ;return 1 ;   };so in 2 frames first frame draws whole gui widgets.in second frame draws blank black screen ( in a second 12 times gui widgets, 12 times black screen is beingdrawn ) .But this cleans the text flickering .but causes whole screen to flicker:):)  i did this to clear whole screen once with black after a text is written and it worked..SO this is all about the idea.İs there a way to force d3dxfont for drawing its texts on backbuffer or on any texture/surface.  Or am i completely wrong.LPD3DXFont->DrawText(...) draws itself on backbuffer.then what causes this flickering?    thanks for your help & replys   
  I'm not entirely sure what you're asking. The font drawing routines do defaultly draw onto the backbuffer (or screen, if you have no backbuffer). I'm not sure if there is a way to make it draw onto another surface -- but it sounds like it's probably possible. (A good question for a more experienced DXer on here :P)As for the flickering, are you sure you configured your backbuffer properly when you set up the D3D_PRESENTPARAMETERS? Specifically, the BackBufferWidth/Height, BackBufferFormat, and BackBufferCount. If there's no backbuffer, then yes, I'd imagine you'd get some serious flickering going on. :)   ;  i have one backbuffer.i have tried with 3 backbuffers also .nothing changed.i dont think lpd3dxfont is drawing it self to backbuffer because.if so there wont be  any flickering.MyWidget background is not flickering ...my widget texts' are flickering..  i meant in my first post that to change flickering in one drawing i drawed the whole widgets.in second drawing i drawed black blank screen .So i assured that there will be a blank screen drawn after the gui texts and gui backbuffer is drawn.Of course this caused whole screen to flicker (because our eyse can determine in second turn program draws only blank screen).But with that i also assured that there will be a cleaning after the text is drawn (a lazy double buffering..i used the front buffer as a backbuffer i mean .)that solved the problem about text.Because blank screen is drawn in second render after text is drawn in first render.  My question is still there ..i dont think that LPD3DXFONT is drawing itself to backbuffer ..it is drawing it self directly to the front buffer...and there must be a way to force it for drawing backbufer...if anyone wants i can send you the .exe to understand what i've tried to say.(send me your emails  serdarosman@gmail.com );  All rendering is done to the current render target, which is typically the back buffer.  You cannot set the front buffer as a render target, so D3DXFont is not rendering to the front buffer.Try downloading this d3dx demo:http://www.drunkenhyena.com/cgi-bin/view_cpp_article.pl?chapter=3;article=17Run the exe and see if you see the same flickering.  If not, then you can look at the code to see what it does differently.If that doesn't help you'll need to give us more detail to help you with your problem.
