• Visual C# Urgent........Inheritance.

  Hi, I want to design a base class in such a way using that i can define only one derived class. if i define another class it should give an error. There aren't any really good answers to that one. Although, I've always thought it would be nice to have something that allowed you to limit the derived classes of a base class. You could, for instance, limit the derivations from XmlNode to the set of valid XmlNode types. The closest thing I have seen in any language, though, is Java's enumerations. To answer your question, if the base class and derived class exist in the same DLL, you could always make the base class's constructor have internal visibility. Can you tell us more about what you're trying to ...Show All

• Visual Studio 2008 (Pre-release) How do I force a template to be instantiated in a test?

  I'm writing unit tests for view classes in a WPF application I'm working on. I want the test to verify that the view will invoke certain methods on my viewmodel class when it is fed certain input. I've run into a problem: unless I actually open up a window to host and show the view, templates used inside the view don't appear to be expanded. For example, the way the view presents certain items from my model is to create a ContentControl with its Content property set to refer to an item from the model, and with its ContentTemplate set to a template that will display the item from the model in the way that I want. I'm trying to simulate user input such as mouse events by calling RaiseEvent directly on elements in the UI. This works fin ...Show All

• Visual Studio Express Editions how to make a rich textbox print

  A friend and i mades text editors and we wanted to know how to make the docyument print thanks ahead Josef Stalin C# is extremely similar to VB: when asking a question on how to do something other than how to create a for/next loop, or syntax related questions, then you will use the same commands in C# as you would in VB. For example, to set the cell of a DataGridView in C# is exactly the same as in VB. Some samples are only in C# or visa versa. In addition, it pays (sometimes literally) to be conversant in both. Remember, also, that the question/problem is important only to the poster and not anyone else - to get the results needed you have to be versatile in accepting what answers you get. ...Show All

• SQL Server Accessing SQL Server 2005 Express

  I recently downloaded SQL Server 2005 Express Edition. Everything was installed correctly without any problems. However, when I went to my Program list, the only thing listed for Microsoft SQL Server 2005, was Configuration tool. Where is the actual program where I can write and run queries How do I access the server I think that the 'default' installation only installs SQL Server. If you want the client tools, you will need to insert the media again and select Client Tools (or something like that...) ...Show All

• SQL Server Variable Value: How do I set it from value in flat file at runtime

  I have a number of DTS packages I am trying to convert and am totally new to Integration Services. I have a flat file that I reference to get a date that I use in some SQL statements in the package. It seems like the best way to do this would be to create a variable to hold the date and set it at run time from the flat file. I've been searching the documentation and the forum and can't figure out how to do this. This is so basic that I feel like an idiot putting it on the forum but I need some help. This whole Integration Services thing is a big shift from DTS (which I eventually became pretty good at) Now I'm back to ground zero. Any help would be appreciated. If you can direct me to any basic training resources that would be cool t ...Show All

• SQL Server How do I get number of fields returned by query?

  Hi. I am trying to get the results of a dynamic sql statement into a #table, in order to filter them. Given that I don't know how many fields will be returned, how do I accomplish this I believe I need to create the #table in advance, and then run the dynamic string as part of an insert [eg 'insert into #table exec (@sql)' ], but in order to do this I need to know how many fields are going to be returned. The results might also be returned by a procedure rather than a simple SQL statement, so I can't just parse @sql to get the fields. As an example, declare @sql nvarchar(200) select @sql = 'select "a" as ColA, "b" as ColB' exec sp_executesql @sql returns two columns of data. I think I need to get t ...Show All
