Re: How to change the caption Dominik Reichl3-Jun-03 4:44 Dominik Reichl 3-Jun-03 4:44  SetWindowText("Your window text here"); -Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do?? Knowing when a dos command ended Shay Harel3-Jun-03 3:27 Shay Harel 3-Jun-03 3:27  Hi, I use ShellExecute to run some dos commnds from by application. Everything works fine but I have to sit in a tight loop to wait for the command to finish like that <br /> do<br /> {<br /> retval=WaitForSingleObject (sei.hProcess, 0);<br /> } while (retval ==WAIT_TIMEOUT);<br /> This makes my application hang the PC for a long time. Any elegant way to do it ? Shay Re: Knowing when a dos command ended Rage3-Jun-03 3:32 Rage 3-Jun-03 3:32  Do exactely the same code in a separate thread. ~RaGE(); Re: Knowing when a dos command ended Anders Molin3-Jun-03 4:39 Anders Molin 3-Jun-03 4:39  Use CreateProcess(), then you'll get a handle you can wait for with WaitForSingleObject() - Anders Money talks, but all mine ever says is "Goodbye!" Re: Knowing when a dos command ended Rage3-Jun-03 5:00 Rage 3-Jun-03 5:00  AFAIK, this hangs the app as well, no ? ~RaGE(); Re: Knowing when a dos command ended Ryan_Roberts3-Jun-03 5:24 Ryan_Roberts 3-Jun-03 5:24  Yup. But using a kernel wait instead of a busy wait would be much nicer for your CPU. If you want your application to continue to respond to input, then you should use MsgWaitForMultipleObjects() with a message pump. This lets your application respond to input and paint messages while waiting for an event to become signaled. Ryan "Everybody has a right to be stupid, but some people abuse the privilege."

I'm interested in this (already tried something like that, but kept having my app crash, probably because of the message queue ...) ~RaGE(); Re: Knowing when a dos command ended David Crow3-Jun-03 6:29 David Crow 3-Jun-03 6:29  That's because the time-out interval is 0, which means test the object's state and return immediately. Supply a reasonable time-out interval such as 2000.

Re: how to add Mouse Buttons in C++.NET Xander803-Jun-03 2:47 Xander80 3-Jun-03 2:47  Select the resource (dialog) where you want to add the mouse buttons to, in your resource view. Right click on the resource in the right document view. Select properties from the pop-up menu. A new window appears, click on Control Events in the toolbar. This shows all events for all the controls in your resource. CFormView key control doctorpi3-Jun-03 2:26 doctorpi 3-Jun-03 2:26  Hi guys What's the method to control a key pressed when we are working with a CFormView? I've tried OnChar but when the key is pressed the method is not called. Best Regards Dr.Pi Re: CFormView key control Rage3-Jun-03 3:40 Rage 3-Jun-03 3:40  OnKeyDown() ? ~RaGE(); Re: CFormView key control doctorpi3-Jun-03 4:13 doctorpi 3-Jun-03 4:13  I have the same result as with OnChar Maybe I'm doing something wrong, and it's a silly mistake. Thanks anyway Dr.Pi Re: CFormView key control Roger Allen3-Jun-03 6:11 Roger Allen 3-Jun-03 6:11  Your best chance is probably PreTranslateMessage checking for pMsg->message == WM_KEYDOWN and pMsg->wParam == VK_key_of_interest You can also make use of GetFocus() to check which control the input would have been aimed at.
