• nesrine Datagridview problem

  HI, i am having a problem with datagridview while adding new records. if the row being added loses focus (clicking elsewhere on the grid), the row being added is lost. Is that a property of the datagridview! or is there a way to prevent this from happening. i guess i need something like If ( in rowadd mode ) then onmouseclicks events do nothing... or ignore that event such that nothing is done and my row will remain there. anyone got the idea of how this is to be achieved or know the real solution. I handled both the dataerror and the defaultvaluesneeded events, still the same problem. I still lose the row if it is completely filled if save button is not yet pressed. The hic is that.. see code : groupbox 1 ...Show All

• ChenHeng datagrid troubles with stored procedure (vs 2003)

  I have the following code: Dim daGrid1 As New SqlDataAdapter(Me.SqlCommand1) (a stored proc) Dim dsGrid1 As New DataSet dsGrid1.Clear() daGrid1.Fill(dsGrid1, "top") DataGrid1.DataSource = dsGrid1.Tables("top").DefaultView I set the command to a stored proce and fill a dataset, then set the datagrid1 to the dataset table. I can then see the data grid on the form filled out. I need to change the column headings, hide some columns, then click on a row, and get the hidden field and pass it on to another form. I thought I would need a table style for that. But when I try to add one, I get: "The data grid table styles collection already contains a table style with the same mapping name." ...Show All

• Daniel Hardjosuwito DataGridViewTextBoxCell that supports 'overflow'...

  Hello, I'm looking for a way to support 'large' text value in TextBoxCells so you get the overflow/excel effect and the string is displayed over the surrounding cells... I've tried to override the Paint method (by manipulating the clipbounds and cellbounds) but that alone is not enough.. (since the next cell method will paint over).... Ok, i finally got it working (the POC anyway) I simply extended DGVTextBoxCell with a public ExtendedPaint method (a simple call to the base.Paint). Then i extended DGVRow with a PaintPrivate method that does the following: call the base.PaintPrivate and then redo the looping over visible columns,allocate additional space for cells that are of my extended DGVTextBoxCell Type and call their ExtendedPai ...Show All

• Knvb1123 Localize messageboxbuttons

  Is there a way that i can localize messageboxbuttons meaning if my form is frensh: messageboxbuttons instead of "Yes" and "No" should be "Oui" and "Non" and so on Thank you .NET uses Windows to generate and display the message box. Windows localizes it to the installed language so all message boxes in every app use the same language. So, to get Oui or Non, you need to run the French version of Windows. If that's not good enough, you'll have to make your own. That's not as easy as it looks...

• DalekDAW Help on working with services

I have never developed a service, suddenly I needed to have one of my processes running as a service, this process is quite complex since it download files from several servers, read the files, manipulate contents, insert the content into a database, create logs of every movement, etc. I tried to convert my project (which is an exe file with a dll dependency file) into a service with the exact code of my exe file, it looked ok now but it seems to work unpredictably and erratically, the manual process never have any problem so far. My question is if the service model has limitations against a manual process, like connections to other servers, database connection, depe ...Show All
