• Microsoft ISV Community Center Forums Elegance (and performance) Problem

  Hello, I developed a class (class CMatrix, that holds a lot of functions not really related to the other class) to use in another class. Currently, it's working real fine, but I don't know if there's a better way to handle with this. What I do today is, in the main class: Dim Matrix As CMatrix ... somewhere in a sub or property Matrix = CMatrix.MergeSort(Matrix) ... rest of the code If my CMatrix could acess the data in the main class, it would be fine, bc I wouldn't have to pass nothing. Thx in advance =] In most cases, you don't want to use pass by reference. It usually make the function unintuitive, unless you need to output more than one variable from a function. See those common ...Show All

• Visual C# Private constructor

  What is the use of a private constructor as it is not getting called with an object creation in .net/c# I would greatly appriciate if anybody could clear my confusion here. Thanks in Advance..................... Use a private constructor to implement the Singleton and Class Factory design patterns. You'd supply a static method that creates the class instances for the client, thus carefully controlling how they are created and initialized. Missa's example of OleDbTransaction is different, its ctor is marked "internal". That's another technique where you allow only "trusted" classes within the same assembly to create the object. Trusted, as in, can be counted on to properly initialize the object. Possib ...Show All

• SQL Server upgraded from 2000 to 2005, Trigger won't fire now..

  Hi all, I recently upgrade my db from sql server 2000 to sql server 2005. I had a trigger that was working perfectly prior to the upgrade. It is an update trigger. Now when an sp executes and updates my table the update trigger does not fire. The really weird thing is when i manually execute an update in a query window against that table the trigger DOES fire. Is anyone aware of how this would be possible Why would the trigger execute when the update is run manually as opposed to when the stored procedures executes the update Are there server/system/session setttings or permissions that could cause the trigger to not fire This can only be due to the db upgrade. Nothing has changed in regards to the code. I have checked and rechecked that ...Show All

• .NET Development Security for new serial port class

  Does anyone know what permission is needed to use the System.IO.Ports class eg.

• Game Technologies: DirectX, XNA, XACT, etc. 2D animation

  I am trying to make some simple animation, like 5 frames. I have all the bmp files with the frames I want. How do I allow them to be animated in my game and how do I string them together. Each time Draw() is called, you can draw the next picture in the sequence. And then when you hit the last image, revert back to the first one. You can also add a delay between each frame, so the animation will run slower, and at the same pace on every computer. ...Show All

• Smart Device Development Command Button (C#.Net VSN 2005)

  Hi I have 100 buttons on GroupBox of a form. ie., Button1, Button2....Button100. I need to change the Color of their texts in a single event. If so far, I don't need to mention "this.BtnSurah11.ForeColor = System.Drawing.Color.Maroon;" for each and every buttons. So is it possible to build up a loop for 100 sequences which define the object (button), from the loop can we change their property For example int i; for (i=1;i<=100;i++) { String Str = "Button" ; Str + i .forecolor = System.Drawing. Color .Maroon; } or foreach ( Control control in this .Controls) { if (control is Button ) ...Show All

• SQL Server Using FreeTextTable Conditionally

  Hello all! I have a stored procedure that accepts a parameter @SearchTerm that may be null. In my WHERE clause, I check for all records where @SearchTerm is null, or are LIKE '%' + @SearchTerm + '%' when not null: SELECT (some records) FROM (some tables) WHERE @SearchTerm IS NULL OR (some fields are LIKE '%' + @SearchTerm + '%'); I am trying to use FTS with a FreeTextTable to make our search ability more robust: SELECT (some records) FROM (some tables) JOIN FreeTextTable(tableName, columns, @SearchTerm) ft ON ft.[KEY] = tableName.[KEY] However, because @SearchTerm can be null, meaning the user is not filtering our records by a search, doing a JOIN to a FreeTextTable throws an error (cannot have null as search string).

• Visual Studio Express Editions Help regarding the learning resources

  Hi, I followed the learning resources on http://msdn.microsoft.com/vstudio/express/visualcsharp/learning/default.aspx Lesson 9: Databinding Data to User Interface Controls. Here the problem I encountered: After adding the database and the data source. I selected datagridview than drag and drop the customer data source to my form. Started the program, I realise from the datagridview I could not save changes to my database. Why is this so Is the save button not programmed correctly well the datagridview will not automatically commit changes to the database but rather the datasource (Dataset for example) so you would need to program a button to save the info back to the database using the DataAdapter Update method. ...Show All

• Visual C# Object/Entity/Class Generator from DataSet/Schema

  Hi, I've googled around and searched this forum as well. I'm looking for a generator to make an entity class from my dataset. Currently I'm using XSD in an pre-build event (VS2005), which looks like this XSD "$(SolutionDir)MyDataSet.xsd" /c /outputdir:"$(ProjectDir)Auto-Generated" /namespace:MyNameSpace.DataTypes. I'm not very happy with how the generated code looks like. My class is named MyDataSet.cs, and the customer object is named MyDataSetCustomer. I would prefer just Customer. Previously I've used XSDObjectGen, but I've found no .Net2 version of this. Does anybody have some nice utility or tip of how to make good entity classes from datasets ...Show All
