• Visual Basic TableAdapter Query Question

  Hi All, Quick question, when I create a table adapter query like SELECT salary FROM employeetable WHERE employeename = and name it GetSalary when I call the query from within the code it asks for an Integer value for the parameter and if I put in an employee's name I get an error stating that the string value cannot be converted to an Integer.

• Visual Studio Big image causes blank pages even after scaling it down and deleting it!

  Local Report. I'm not sure what the issue is here but my problem started with print layout having too many pages - adding a blank with header and footer for each real page. I made sure that nothing was near the margins and even set the margins to .5 for each report and subreport. No good. So I searched the forum and found other complaints about this. One person said that he recreated the report and didn't have the problem after that. So I began with a new main report and started adding stuff to see when the problem started. Once I added the icon, that did it. The image is embedded in the report so the image1 source is set to embedded a ...Show All

• SQL Server Configure Report Server with SQL Server Express with Advanced Services.

  I'm having a world of trouble with the Reporting Services Server. The install went fine. I went in to configure the Report Server and when creating the Report Server and the Report Manager virtual directories I get the following error: "The virtual directory could not be created. The previously set virtual directory will still be used." The problem with this is that I have not previously set a virtual directory.

• Visual C# Merging namespaces as one

  Is it possible to merge multiple namespaces as one The reason I want to do this is because I want to inherit someone elses control, but use my own namespace. Using my own namespace stops the UI design tools from working. What I need is to be able to make C# think my control exists within the other name space, while still existing in my namespace. Maybe I'm asking for to much. Namespaces exist to create seperation. You can't fool the IDE into thinking one namespace is the same as another, although you can use a using statement to make a namespace part of local scope, obviously. ...Show All

• SQL Server Confused whether to generate a nextNumber or to use Autoincrement

  In my office we generate an unique ID on a table by  doing something like: Declare @ID int  SELECT @ID= ISNULL(MAX(@ID), 0) + 1 FROM MyTable Are there any benefit in using this methods rather then the Autoincrement functionality provided by sql server Could somebody explain which method is better and why Hi, I think there is a benefit is that you will not has gaps in the ID field if you rolled back your transaction. if you have an identity field in a table and the next value for example will be 100  and you make an insert statement then rolled back the insert then the next insert statement ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Displaying Static Background with DirectX9 Example?

  Can someone help this poor DirectX newbie by pointing me to an example of how to display a static background from an image file using C++ (or C#). I've read that the way to do this is to create two triangles from vertices, load the image into a texture and map the texture to the surface. This sounds great but I can't figure out how to do it from the DirectX docs. Currently, I'm trying to do it by loading the image onto an offscreen surface and using UpdateSurface() to copy it to the back buffer. This works great, except when I switch to another application or point down at the task bar the background disappears! So I'm trying to do it anothe ...Show All
