For his thesis he wants to study the effect of subliminal messages. these are messages that u dont see, but your subconscience does pick it up. (like coca cola used in movie theaters to get u to drink more) i managed to get a CWnd* to the desktop window and draw text in it, but i fail to erase it. the only way i can get it erased is InvalidateRect(NULL, NULL, TRUE), this way all the windows get a WM_PAINT message It's obvious that this causes an enormous flicker. I also tried : HWND hNextWindow = ::GetWindow(m_hWnd, GW_HWNDFIRST);<br /> ::InvalidateRect(hNextWindow, NULL, TRUE); but this only results in my taskbar popping up. Anybody got some pointers to get the job done ?? thx, wouter I used to have a life ... now I have a computer Re: draw on desktop Ryan Binns25-Jul-03 0:14 Ryan Binns 25-Jul-03 0:14  CWnd::GetDesktopWindow()->Invalidate(); Hope this helps, Ryan "Punctuality is only a virtue for those who aren't smart enough to think of good excuses for being late" John Nichol "Point Of Impact" total mouse control Raphael Kindt24-Jul-03 22:29 Raphael Kindt 24-Jul-03 22:29  hi world I want to get all mouse messages towards my application... I mean when the mouse move outside the window of my application, my application receive mouse messages nevertheless (and thus mouse coordinates too)! I already use Set/Get/ReleaseCapture and SetWindowsHookEx but when the mouse is outside my application I couldn't receive mouse message... My question: How to receive ALL mouse message towards my application? Even if the mouse moves outside the main window of my application... Thanks in advace... Hello World!!! from Raphaël Re: total mouse control Dominik Reichl24-Jul-03 22:36 Dominik Reichl 24-Jul-03 22:36  As someone posted already, use SetWindowsHookEx in an injection DLL. -Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do?? Re: total mouse control Raphael Kindt24-Jul-03 22:47 Raphael Kindt 24-Jul-03 22:47  I already do that but it seems don't work... Moreover MSDN says: You should use global hooks only for debugging purposes; otherwise, you should avoid them. Global hooks hurt system performance and cause conflicts with other applications that implement the same type of global hook. where can I find an example using a DLL? Thanks for your help!

Hello World!!! from Raphaël How can I disable/enable a firewire card in windows 2000 through Visual C++ 6.0 Tim Yen24-Jul-03 21:22 Tim Yen 24-Jul-03 21:22  Hi, I'm trying to disable and then re enable a firewire card (or any generic hardware device for that matter) through software. I'm doing this is so I can turn the power off and on to my firewire camera when it goes haywire without having to unplug it and plug it back in. Im programming in visual c++ 6.0 on windows 2000 but any clues as to where to begin even if in other languages would be appreciated. regards, Tim Re: How can I disable/enable a firewire card in windows 2000 through Visual C++ 6.0 Iain Clarke, Warrior Programmer25-Jul-03 0:22 Iain Clarke, Warrior Programmer 25-Jul-03 0:22  If you know the name of the driver, you can use the following API functions to start / stop / control a service / driver. OpenSCManager OpenService ControlService. Look them up on MSDN for details on how to use them. Alternatively, you may be able to find out the IOCTL codes to send a "reset" to your driver using DeviceIOControl. Iain.

At the moment I have a modeless dialog window that has dx7 running in it (aka window mode) just drawing stuff. I have set it to topmost and I am also using this (below) every frame it draws, although it does seem to slow it down SetWindowPos(hWnd, 0, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_SHOWWINDOW); Is there any other way to do this?? And when I say draw over other apps I mean games like Half-Life Qauke 3 etc. Thanks in advance. Re: Draw over Direct3d/Opengl applications Alexander M.,25-Jul-03 2:20 Alexander M., 25-Jul-03 2:20  hehe, opengl is very easy, especially for quake and half-life! half-life calls glEnable every frame before drawing anything! inject a dll by using for example ForceLibrary(http://mitglied.lycos.de/yoda2k/[^]), hook the GetProcAddress function and in that hooked function compare every entered lpProcName value with "glEnable" and hook this function! when your hooked glEnable is called, call the original one, then draw your own objects! DON'T FORGET TO PUSH THE MATRIX BEFORE DRAWING!!! you can find source codes of wallhacks at http://www.unknowncheats.com[^] another important thing: MOST OPENGL MANUPULATION ARE DETECTED AS CHEATS AND MAY CAUSE CDKEY BAN! Don't try it, just do it! Transparent Drawing Anonymous24-Jul-03 15:22 Anonymous 24-Jul-03 15:22  Hi, I am drawing a polygonal with Polygon() and using SetBkMode(TRANSPARENT) but instead of getting the original image with the lines of the polygon I am getting a white image with the polygonal lines on top. When I use DrawText it does draw the text as an overlay on the image. How do I do the same with drawing polygons? Thanks, Re: Transparent Drawing Ryan Binns24-Jul-03 16:01 Ryan Binns 24-Jul-03 16:01  If you're using MFC dc.SelectStockObject(NULL_BRUSH); If not, ::SelectObject(hdc, ::GetStockObject(NULL_BRUSH)); Hope this helps, Ryan "Punctuality is only a virtue for those who aren't smart enough to think of good excuses for being late" John Nichol "Point Of Impact"
