• Software Development for Windows Vista change integrity level

  Hi, All I want to start a process with medium integrity level from a low integrity level process. From http://msdn.microsoft.com/library/default.asp url=/library/en-us/ietechcol/dnwebgen/protectedmode.asp , I found an example which starts a lower integrity level process instead and use the following hard coded Low integrity SID of "S-1-16-4096". What's the value for other integrity levels' SID(medium|high|system) I searched June CTP's SDK and document, but didn't find anything. One more thing is that also following an example from above link, I try to lower the integrity level of a named pipe in the same process which created it, but I got error code 5(access denied). Anyone knows what goes wrong code fol ...Show All

• Visual Studio 2008 (Pre-release) Create WCF Proxy Unit Test

• Visual C# Reflection: define get and set dynamicaly

  Hello, How do I define get and set methods for properties dynamicaly Maybe with PropertyBuilder, but I didnt find any sample. Thanks. What do you mean by define them Reflection involves using meta data to learn about existing classes and object... so to get a reference to the get and set methods of a property named X you might use the following: public class MyClass { private int x; public int MyProp { get { return x; } set { x = value; } } } ... Type t = typeof(MyClass); MethodInfo writeMethod = t.GetProperty("MyProp").GetGetMethod(); MethodInfo readMethod = t.GetProperty("MyProp").GetSetMethod(); But th ...Show All

• Smart Device Development WebBrowser back key (Escape key)

  Hello! I've got a form where I've added a WebBrowser control. The WebBrowser has focus. I now want to capture the back key event while the WebBrowser has focus. I hav already tried to use "KeyPreview = true" in the form of the WebBrowser with no luck. I dont want to disable the key, just let the key display the previous group of controls that been showing before the WebBrowser. How can I do this Thanks, Martin The answer to the problem I mention above is to not look at Keys.Back/Keys.Backspace but ONLY Keys.BorwserBack when determining if you need to navigate back.

• Visual C++ Dynamic Sound Creation

  I have been thinking recently that I would like to do something with dynamic sound, or in other words; creating sound during runtime without the use of .wav files etc. I know that this is possible because this method has been used for things like speech engines. Microsofts TalkIt for example has the ability to have 5 different varaibles factored into the voice; Pitch, Volume, Accent (only english and spanish in TalkIt), Pitch Quality (Natural, Monotone, Sung), and Vocal Effort ( Normal, Breathy, Wispered). So I was wondering if anyone knew how you would go about doing this, or if you knew of somewhere there would be tutorials on this creating of dynamic sound. Please direct this question to the multimedia newsgroup at http://ms ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Update frames for 2D animations

  Hi all, In my previous program (C# + MDX), I use the Timer in System.Windows to update the frames by using suitable time interval. Now I would like to change to use XNA. But I don't know whether the Timer class will be supported in XBox360. Therefore, I would like to ask whether there are better ways to show 2D animations. I have read the 2D animation in "HELP". But I would like to know whether there are any other approach. All the animations update the frames in the 'Update" function and therefore all the 2D animations update the frames in the same time. If the fps varies, the timing for refreshing the frames also varies. That's not what I want. Thank you very much The Update method gives ...Show All

• SQL Server RB - Multiple Data Source for Report Builder

  I add two data sources to the designer. Create a new dsv using one data source first. Then right click in the designer to add a new table. This time I use the second data source. When I create a Report Model and run it, an error occurred: "Message: Invalid object name 'dbo.tblTrade'. Command: SELECT COUNT(*) FROM [dbo].[tblTrade] t" It does not recognize the second data source. Look at the property of the dsv, it only points to the first data source, not the other one...

• Smart Device Development Prevent standby/keep app running in standby?

  Hi All I'm currently writing my diploma thesis and as a part thereof i am writing a WM based application to constantly log some data (various sensor input via Serial, picture capturing, audio recording and GPS via Bluetooth) which will later on be used for some data mining/context awareness stuff. It is absolutely crucial that i have a constant stream of incoming data that is not interrupted by e.g. standby, be it system or user initiated... And that is exactly where i am stuck now... :-( Does anyone know how i can prevent my wm 2005 PPC device from going into standby, even if the user clicks on power off button However, if this is possible, will the keys and the touchscreen still be locked (not a must, but would be nice) (Btw.We ...Show All
