The user password for the administrator of the system? I don't believe that is possible...I certainly hope it is not, otherwise anyone with rudimentary knowledge of WMI could learn my password. :-p

You can't. It's one-way encrypted. There are no functions anywhere that will give you the password.

How to show the screen with virtual keyboard on Pocket PC 2003 device, without prompting user to click the icon? I need it to show every time user click in edit box.
thanks.

Add a Microsoft.WindowsCE.Forms.InputPanel component to your form. Add a SetFocus handler to the edit box. In the handler, set the Enabled property of the InputPanel object to true. If you want to hide the panel again when the user moves to a different control, add a handler for the KillFocus event and set Enabled to false.
Stability. What an interesting concept. -- Chris Maunder

Hi,
This might be a stupid question, but is it possible to incorporate directx/opengl into say a data acquisition application? i've pretty much tried every technique possible from double buffering to more efficient screen invalidating but the refresh speed is way to slow. So I was wondering if there is a way to include hardware acceleration into a win app.
thanks,
Brian

Yes, of course. I've read about some apps that use Managed DirectX to do rendering; it's certainly possible, however you don't get the native look and feel of the standard Windows widgets.
I suggest looking into Managed DirectX or Tao OpenGl.

so when you say that i wouldn't get the native look and feel, does that mean the screen would blank out similiar to when running a video game?

No. I mean that, for instance, if you wanted a TreeView control, you'll have to write your own treeview control, because DirectX doesn't draw these for you, you'd have to draw them yourself. And if you're drawing them yourself, they probably won't look exactly like they do in standard Windows applications.

What are you actually trying to do that is causing refresh problems? Maybe, there's another work-around.

Basically i'm creating a program that analyzes waveforms. Each waveform can consist of around 200 data pts. There can be up to 8 waveforms displayed at once. The app allows the user to "scroll" through the signal to view a zoomed in portion of the waveform. So basically each signal has 3 views that get updated all at once, which causes a lot of processor usage since almost the entire screen gets redrawn. Right now i'm using 3 timers to update each of the views. Even with the delay in drawing, i'm almost maxing out on the processor. I've tried several different drawing techniques that include double buff and specific invalidating but no real luck. I would do the project in c++ but the time-frame i have is rather short so i decided to go with c#. If you have any suggestions on techniques please let me know.
thanks,
Brian

Just some FYI: If you are graphing a series of point as a continuous line make sure to use the DrawLines function and not DrawLine in a loop. I found a huge performance difference between the two when I was writing a graphing control. I don’t know if you are already doing this, but I thought I might mention it in case you’re not.

If you do want to use DirectX take a look at overlays. That will allow you to create an area within your window to draw your charts without giving up all of the other UI niceties of C# and GDI+.
My guess is that there isn’t anything here that you can’t do using GDI+. Here are a few things to check:
Are you redrawing the background of your graph each time? It’s likely that a large number of drawing commands are spent redrawing an unchanging background every time the graph is drawn. Try caching the background and Blit it to your graph area.
Are you using DrawLine or DrawLines? DrawLines is much faster.
Is it really the drawing that is slow? Have you looked at the code with a profiler to see which methods are taking the longest?
Regarding the double buffering, are you doing the buffering yourself in an off-screen object, or are you using the double buffer control style?
Also, what are the timers for?

Hy,
How can I detect the Office Version of a Windows Client. I need to know it, cause my Apllication had to be compatible with office 2000/XP/ And Ofiice 2003. I need it, to create the right Object, for each Version.
Can I do it directly in .NET with c#?? And how?
Help me please.

this is just speculation but id think it was written in the registry, so all u need to do is find the key that is the correct one and read it

I'd like to be able to report exceptions occuring in a thread to the main application, rather than having the thread silently terminate. Am I missing something obvious on how to do that, or does this involve coding something in the thread's catch block that notifies the application's main thread?
Thanks!

Is the Application.ThreadException event what you're looking for?
Possibly. It says, though, "...when it receives a thread exception from a window procedure." I'll have to see if it works for non-window threads.
