• Windows Forms DataGridView and the automatic ellipsis

  I am working on converting a project from VS3 to VS5. One form has a grid which now uses the new DataGridView. Overall it is great. However, there is one small issue: When the amount of data in a cell is larger than can be displayed, an ellipsis is shown. This normally would be fine. However, this grid displays records from a database and a field may be 30 characters long, but with only 5 actual characters and the rest spaces. The cell, however, still thinks that they are actual characters so the cells always display the ellipsis, even when it is actually empty (only spaces). I have looked for a way to format it with the DefaultCellStyle. ...Show All

• .NET Development Performance of ADO.Net in CLI Console app vs Windows Forms app

  I have been playing with ADO.Net and at first, I created a CLI console application, where I did different things, such as querying the schema collections of a database. I then created a Windows Forms application and did similar things (wrote code from scratch). What strikes me is that some simple calls that took no time under the console app now take a long time under Forms. I use VS C++ and SQL Server 2005 Express on a Win2000 PC and the ODBC provider factory. I establish a DbConnection to the database via ODBC data source, which was manually set up using the ODBC control panel. When I make the simple call: MyDataTable = myDbConnectio ...Show All

• Windows Forms Saved new record, what is the best method for clearing a form.

  OK, this is a nub question by a guy who knows a lot about web but not nearly enough about Windows forms. If I open a new form to create and save a new record (like a new user), what would be the best way to re-initialize the form after the record was saved to start over again with a blank form I do not really want to close the form, because a data entry person may want to sit and enter numerous records without having to open a new form all the time. Is there any way easier than manually resetting each individual control (which could be a pain on complicated forms) Thanks. There isn't a generic way to re-initialize a for ...Show All

• SQL Server SQL Server Express Security?

  We are releasing an application built on SQL Server Express in the next few months.  Our clients are mostly small companies with little technical knowledge, and they will be using our application on desktop computers where everyone likely logs in as the same user.  As such, my thinking is that we setup SQL Server Express as in SQL Server Authentication mode.  This way they could select an Administrator password upon first installation, and manage user names and passwords from within the application itself.  Any thoughts   Also, how would we install this scenario   We haven't been able to figure out how to custo ...Show All
