• Visual C# Parametersized property!?

  I am *very* surprised at the fact that C# does not support parameterized property! The only thing I get is the so-called Indexer, but that does not provide the same functionality as parameterized property. For example, I can write the following code in VB: Public Class test Property Name(ByVal key As String) As String Get Return key End Get Set(ByVal value As String) End Set End Property Property Address(ByVal key As String) As String Get Return key End Get Set(ByVal value As String) End Set End Property End Class The two properties both have a String parameter and both return a String object. However, in C# I can only write only *ONE* indexer: public ...Show All

• Visual Studio JIT Debugging error while trying to play phantasy star online pc

  I'm getting this error everytime i try to load my game under JIT debugging i have managed, native, and script enabled. it's still not working so can someone help me. i have no idea what the problem is To take Visual Studio out of the picture and make sure the game publisher is receiving the error report go to this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AeDebug And change the value of the "Auto" key to "0" instead of "1". This will ensure that the error report is uploaded rather than VS getting in the way. It won't stop pso.exe from crashing however - sorry. ...Show All

• .NET Development The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.

  I just installed Visual Studio 2005 today and I'm already getting an error. This code worked fine on 2003. I am running Windows XP 64 so I definitely have the latest MDAC. Anyone know why I would get this error Dim strConnect As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & GetWorkingPath() & "db.mdb;Persist Security Info=False;" conn = New OleDbConnection(strConnect) conn.Open() There is not a 64 bit version of jet that is why you get that error.  To force your app to use the 32 bit change the target cpu to x86 in the advanced compiler options. http://www.vb-tips.com/default.aspx ID=c8303e25-496d-4288-bc1d-58e5850daf5e ...Show All

• SQL Server Including SQL Server Express as a nested MSI install

  I'm working on an MSI-based install that installs a suite of applications. One of the applications requires SQL Server 2005 Express to be installed or already on the machine, but if the user doesn't want that app installed, I don't want to have to bother with the SQL Server issue; however, if that app is to be installed and SQL Server is not already installed, I want to be able to have it installed automatically during our install in order to make it easier for our end users. The obvious answer to this is to launch the SQL Server Express install as a nested MSI install at the appropriate point in our install. Since the SQL Server install is so complex, I was wondering if this would work if I were to launch the SQL Server install's setup.ex ...Show All

• Visual Studio Embedding shapes in v1

  Hi, First of all congratulations on getting v1 out. It's looking pretty cool! I have been trying to migrate a DSL I developed in the June CTP version, but I have run into some errors. A couple of examples are.. Error 23 A GeometryShape may not be parented on a GeometryShape. In the ShapeMap mapping State to StateShape, the parent element path leads to StateManager, whose mapped shape is StateManagerShape. Error 26 A ImageShape may not be parented on a GeometryShape. In the ShapeMap mapping EnterCommand to EnterCommandShape, the parent element path leads to State, whose mapped shape is StateShape. Basically my DSL is similar to UML statechart notation, but I want to be able to nest states inside one another hierarchically in ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 360 Texture Mapping Problems...

  Ok ... Just got my 360 creator club membership and tried my first 360 game routines. I have a problem with textures... I'm using DrawableGameComponent's. I'm rendering a tube with a texture and fogging (to black). Camera is inside the tube. The tube is made up of triangles with a repeating texture. Looks great until... I've now added a component that plots a sprite (a simple game logo). The textures on the tube are now drawing incorrectly. Texture seems to stop repeating (when texture co-ordinate goes over 1.0f). This only happens when I plot a sprite (via spriteBatch). Help. I'm guessing something on the graphicsdevice is being set when a sprite is drawn ...  but I can't find out what. Does anyone have any ideas I.e. ...Show All

• Visual Studio 2008 (Pre-release) Property trigger ExitActions

  Trying to use trigger.enteractions and exitactions in a control template triggered from visibility=visible. Both enteractions and exitactions trigger when visibility is set to visible. Does anyone know if this is a bug (June CTP). Thanks, John A quick ad-hoc experiment (attached below) indicates that there's no bug fitting your description, at least not in the general case. There is something else specific to your scenario that interacted/interfered with the trigger, causing the behavior you saw. If you could post markup demonstrating the problem, we can dig deeper to understand it. In the meantime, for reference purposes here's some markup demonstrating a ControlTemplate Trigger's EnterAction ...Show All

• Visual Studio Team System Major Modifications of Task.xml cause project creation failure. (process template is uploaded without errors)

  I am beginning to think that there are limits to the extent that the task.xml WORKITEM can be modified; I am guessing the problem resides in the generic tasks that TFS places in your "todo" list at the creation of your project. There seems to be no way to turn off the creation of these assignments when you create your project. My experience is that I can modify Task quite a bit; but as soon as I make too many modifications to the <TRANSITIONS> I will get an Exception (see below). I can even cut and paste from "Bug.xml" all my states and transitions that work just fine in Bug, but fail when imported into Task.xml. Additionally I have found that if I try to make my own field (MPRI.Common.EstimatedHours) requi ...Show All

• Software Development for Windows Vista Interoperability with Sun/Oracle/Fujitsu WS-CAF (Composite application Framework)

  Hi, Can someone tell me if there are still two standards emerging, diverging or converging in the Web Services transaction space A year or so ago, I was reading about Oracle's and Sun's Composite Application Framework as a rival to what Microsoft, Bea and IBM were doing. Is this still the case Is there a winner/loser or hybrid emerging Is it a case of Java and .NET demarcation flowing through I am specifically interested in the WS-AT subset of transactions so feel free (in fact please do) confine your answer(s) to this realm. Heuristic txn resolution is anathema to me (and by the looks msdtc) but Oracle/Sun (and curiously IBM) seem to live for it! They got "heuristic hazard" all over the place and are quite happy if a ...Show All

• SQL Server Copy & paste of custom task loses internal property settings

  We have a built a custom control flow task that we use frequently. It has a simple user interface form where we can set certain properties. Problem is, after I configure it once and then copy and paste it all of the internal property settings seem to be lost on the newly pasted task. When I open up the editor for the task all of the properties are displayed visually in the editor form, but the properties pane is empty. How can this be corrected I'm wondering if this is a SSIS bug or if the custom task needs some code to either prevent this situation or finish off the setting of internal properties Has anyone else created a custom task with a UI form that they can copy\paste without losing custom int ...Show All
