• Windows Forms restrict Cell Navigation to certain column

  I have got a grid with CheckBoxColumn and TextBoxColumn. What I need is to restrict the cell navigation to TextBoxColumn field. Can any one help me. Reagrd Anil Well, I don't think you'd want it to be readonly if it's a checkbox. Obviously it's a checkbox for a reason and needs user input. I think what's being asked here is how to stop the user from selecting the cell using the TAB key, arrow keys, ENTER, etc... to move around the grid. Let me know if I'm on the right track. ...Show All

• .NET Development Calculated column

  Hi Folks, I have a calculated column in a dataset in my VB 2005 app (added to data set, but not in database) that uses values from 2 other columns multiplyed, and displays that number for the user. Quantity(dec, 18) * Rate(dec,18) = caluculated column 'Total' (dec,18) When ever the user places a decimal number in the quantity column, the value rounds up to the next whole number -- I do not want the number round to the next whole, and also need to limit the results to 2 decimal places. I first thought this was a control problem in a data grid -- it wasn't; I tried seperate text box controls, but with the same results - numbers round up to the next whole. The only other place I could have this problem is in the data set calculate ...Show All

• Visual C# Best way to get around not being able to dynamically cast?

  I'm trying to do something where it would be nice to be able to dynamically cast. I know this isn't possible in C# so I'm trying to figure out the best way around this. Basically the setup is I have a 'Segment' class. Then a have a bunch of classes that inherit from the 'Segment' class. Then I have a Segment collection class that has an ArrayList that stores different 'Segment's. What I want to be able to do is have a method that takes in a Type (which will be one of the classes that inherits from 'Segment') and have it return an array of Segments of that type. Something like this: private ArrayList Segmants; public Segment[] GetSegmants(Type reqType) {      ArrayList thisList = new ArrayList();    &nbs ...Show All

• SQL Server What SSIS components must be loaded onto the server?

  What SSIS components must be loaded onto the server To run an SSIS ETL program, exactly what executable, components, programs, etc. must reside on the server that will be running the program. Our developers write an test their ETL programs locally, on their desktops or laptops, but must upload the scripts to the production server for execution. Obviously, they are not going load Visual Studio and SQL 2005, etc. up to the server just to run the scripts (tho SQL 2005 may be on the same box as one of the DB engines used for ETL). Any info would be appreciated. hi Craig, I have installed the SQL Server 2005 Express Advance edition on Windows 2003 Standard Server.
