• Visual Studio 2008 (Pre-release) Why no "raise to power" operator in Expression Tree API?

  Hi, Is there any special reason for not including a "raise to power" expression type in the expression tree API VB has such an operator, for instance... Here I show a situation where having such an operator would be desirable: http://www.elguille.info/NET/futuro/firmas_octavio_symbolic_computation_EN.htm Best regards, Octavio Hernandez Madrid, SPAIN The operators designed into the expression trees were limited, not to any particular language, but to the native runtime support for these instructions in MSIL. Everything else is intended to be incoded as method calls, just like your language compiler does. The "raise to power" operator is encoded as a call to System.M ...Show All

• Visual Studio Express Editions Newbie C# Programming Question - Alarm Clock Program

  Hello I'm brand new here trying to learn C#. I spent many hours trying to write a small Windows application alarm clock program. It sits in the system tray and you can set the alarm to a certain time and it will play a wav file. My question right now is how do I check the current time against what the user has selected for the alarm time I've tried to do it many different ways and it never seems to work. In the timer tick event I have something like this: private void timer_Tick( object sender, EventArgs e) { if (DateTime.Now == alarmTime.Value) { this .Restore(); Player.SoundLocation = @"C:\Windows\Media\ringin.wav" ; Player.PlayLooping(); } } Obviously the (DateTime.Now == ala ...Show All

• SQL Server weird and funny question

  I specified configuration like shown below "select * from table where id<>***" always doesn't work however i changed that like "id != ***" working! Who can tell me why Is the value represented by *** in your example ever NULL If it's NULL then the where clause that is send to the SQL engine will be "WHERE id <> NULL" or "WHERE id != NULL". This is an invalid syntax but you will not get an error, instead you will get unpredictable results! The correct syntax is "WHERE id IS NOT NULL". Thanks, Greg Van Mullem ...Show All

• Visual Studio Team System branching files twice to the same branch

  Hello, We are moving our source code control system from pvcs to tfs. During this process I encountered the following strange behaviour during a branch operation. I'll list the actions I performed. 1. create a directory with a file under source control : $repository/main/A/file0.txt 2. branch the 'main' folder to branch 'test', using the branch UI. This generates $repository/test/A/file0.txt 3. I then found out that I forget to add file1.txt to directory A and to branch that too. So I created $repository/main/A/file1.txt 4. I did exactly the same branch operation as in 2., i.e. branching main to test 5. The result is not that $repository/test/A/file1.txt is created as pending branch checkin, but that the entire main ...Show All

• Visual C# Call Method From External Process

  I'm not sure if this is possible, but I need to call a method in a running program from a different program. The method I want to call is being loaded into the remote EXE via a DLL. If I try using DllImport, it does call the method, but it doesn't work correctly. The method is supposed to return its class's member information, but if I use the DllImport from C# to call the method, it doesn't return the actual remote class's members, just some garbage values. Also, the program and DLL were written in C++. For example, TestApp has a class called TestClass. This class has a bool called TestMember and a method called TestMethod that returns the value of TestMember. When I write a program and use DllImport to import TestMethod, it returns true, ...Show All
