BLock NT\98 Workstation (Keyboard & Mouse & Screen).

Let me explain my problem, I built a system (I used C++Builder 4) that do remote control over clients from server. The Client program contains alot of option of control. I want to add an option that full Block\UnBlock the client computer in The RUNTIME. * Now. I need a code (C++,VB,ASM or ...) that Block\UnBlock NT\98 Workstation in The RUNTIME(without Rebooting) :- 1- Full Block KeyBoard (All Keys and TaskKey specially Ctrl+Alt+Del,Ctrl+... in Win NT\2000). (must work with DirectX (block direct input) 2- Block Mouse.(must work with DirectX (block direct input); 3- Block Screen with a BitMap message on the top screen. Must Block the screen without hide,close or kill the program that was in the screen. (mean when DirectX program run on then screen, the BlockScreen do not close it just but a full screen message on it. * For Example see the NetOp School program that do Full Block on the client.([login to view URL]) * please let me see a demo before i accept any bid. * please test the demo on Win 2000\NT before send me. * please test the demo with DirectX before send me.
