• Smart Device Development updating a datagrid

  I am using bound text boxes to update datagrid rows. When I try to update the SQL mobile database with Me.TableAdapter.Update(Me.DataSet.table) I get an error that states "Unexpected Error" and "Upadate requires a valid updatecommand when passed datarow collection with modified rows." Is there another statement that is needed Thank you. For clarification, if a row is added, the data base updates with out a problem. If I alter an existing row, then I am not able to save it. I believe designers would add CommandBuilder automatically unless you don't have a primary key. In that case update/insert commands can not be automatically generated. Primary key is a must have in any database, so please add it, ...Show All

• Visual Basic Two More Questions (VB, VS 05)

  Firstly these two questions should be the last for a while. Q1 : I have a NotifyIcon, with Context Menu but I would like to have my application Close or Minimize to the Notification Area so that a sub-feature can do its thing. I have looked on the MSDN and elsewhere online but cant find actual examples of this is it possible Q2 : As for the sub-feature, its a timer activated process stop (every 10 minutes it stops a process that comes back on its own withing that time period) I have the timer code, and it works, but I would like to have it so that the user has to check a checkbox to start the countdown for the autoclose. No rush on this as I have to further test the rest of the project. Many Thanks Danie ...Show All

• Windows Forms Changing size property

  How do I enable the changing of size of a control like combobox Thanks. regards Alu As for the second question, try the propert CurrentCellAddress which returns a Point object with X equal to the column index (0-indexed) and Y equal to the row index. It worked fine for me when i needed it. However, non of them will work if you are using it in the MouseDown event because, at this point, the cell is not selected yet.It becomes selected after the mouse is up (after the Click event). In the MouseDown event handlers, the current cell will still be the one that was selected before the one you are putting the mouse down on the new cell. To find out what cell the mouse is pointed at when the MouseDown event fires, you'll have to use an ...Show All

• SQL Server RS2005: ReportManager and Forms Authentication : The report server is not responding

  Hi, Sorry for the long post but I'll try to give a maximum of information. I've tried to implement Form Authentication for Reporting Services. Right now, just about everything works as I would hope for, i.e.: When I try to access http://<server>/ReportServer$SQLSERVER_2005 , I am redirected to the authentication form. When successfully authenticated, I can access the report I can display reports throught the ReportViewer Web control by passing the authentication cookie. Etc. (Note: My implementation of Form Authentication was inspired by http://www.devx.com/dotnet/Article/26759/0/page/1 which seems similar to Microsoft Sample) (The $SQLSERVER_2005 suffix is because SQL Server 2000 is also installed on the s ...Show All
