| DaBookshah 03. Feb 2009 | Hmm, weird. I don't get a prompt for a name with or without debugger attached. DialogBoxParamW returns -1, and the messages recieved by the dialog func are in order 0x30, 0x02 (WM_DESTROY), 0x82 (WM_NCDESTROY). Or I could be missing a massive chunk of anti-debugging code somewhere I guess :/ |

| sghctoma Author 03. Feb 2009 | Mea culpa, mea maxima culpa.. I've done a little reading, and now I think I am using DialogBoxParam incorrectly.. I pass NULL as the first parameter (HINSTANCE) instead of the actual HINSTANCE value.. btw, I've tried the program on my, and three other computers (one Windows 7, one Vista and two XP's) and the program ran fine.. it is not clear for me yet, why it runs fine on one machine, and why it doesn't on another.. anyway, I'll upload a fixed version soon.. I hope it will solve the problem... |
| DaBookshah 04. Feb 2009 | I'm running XP SP2 |
| sghctoma Author 04. Feb 2009 | the update has been approved, I hope now it will work for you, DaBookshah.. btw, just out of curiosity: did anybody else experience the same problem? |
| DaBookshah 05. Feb 2009 | Nope, no good :( think it might just be something screwy with my computer. Still only getting WM_SETFONT, WM_DESTROY, WM_NCDESTROY, in that order. Doesn't even get to INITDIALOG :( |
| andrewl.us Moderator 05. Feb 2009 | works here after installed DirectX junk.. XP SP2 |
| simonzack Moderator 05. Feb 2009 | mine says directX initialization failed what happened with directX??? |
| sghctoma Author 05. Feb 2009 | @DaBookshah: I'm sorry to hear that, but I haven't got the slightest idea, what could be the problem.. @simonzack: Is your VGA-card Pixel/Vertex Shader 2.0 capable? The crackme uses PS/VS 2.0. @andrewl.us: I'm glad, that there is actually somebody, who can run it :) |
