• Visual Basic Clarification on project start up in VB.NET

  Hi, i have created a sample project in VB.NET. i have one form(Form1) and a module(Module1) . i have written a sub main function in module and inside it i have asked to show the Form1 as shown below.

• Software Development for Windows Vista Show of Hands! Is WF by itself a viable approach to addressing a customer's workflow needs?

  Like many of us in the forum I am in the all too often unenviable position to influence my client's decisions. I currently have a lot of customers evaluating workflow, many for the 1st time. I personally have avoided building "custom" workflow solutions whenever possible as I have had success in the past implementing packaged workflow or BPM offerings, both Microsoft-based and less recently non-Microsoft-based. It's allowed me to focus my energies on building solutions and solving real business problems, not building infrastructure. Granted, there are customer situations that don't require or afford you the opportunity to buy a packaged solution to address a workflow/BPM need, but I would argue those are/should be the exception n ...Show All

• SQL Server Date lookup in SSIS

  How do I perform a date lookup in SSIS. I have a date with time component in it. This has to be looked-up with a table that contains only a date element. I commonly use a slight cheat on this one, if you make the integer key of your lookup table the difference in days from 1 Jan 1900 then you can calculate the key instead of looking it up. You can also use the same trick with the time portion of neccessary (do the diff in seconds). Hope that helps you Philip ...Show All

• Windows Forms How to deselect the DataGridView row header

  Hi, I'm trying to figure how if it's possible to completely deselect rows, including the arrow symbol in the rowheader cell. The reason I am trying to do this is because with multiple selections (eg. using CTRL key) the user can select multiple rows, but they can also deselect previous selections. Example: - Select first 3 rows with CTRL key - Deselect 3rd row with CTRL key. The SelectedRows collection correctly reflects the change, and now contains only the first 2 rows. Also, the CurrentRow.Selected = false for the third row - But the RowHeader arrow is still on the third row, which is now no longer selected - What I would ideally like is to set the new CurrentRow to be the second row, and the RowHeader to be updated accordingly I have t ...Show All

• .NET Development BufferedGraphics - Rendering

  I have recently started playing with BufferedGraphics class. One piece of functionality that I found missing is rendering to a specific location. BufferedGraphics.Render function does not accept any coordinate parameters. Is there a way around this Rationale: I have a control that has 3 parts that change independently. I have a BufferedGraphics object for each part. On paint, I would like to only update the buffer (contents and size) of the part that has changed. Then render all 3 buffers to the control's Graphics object. Thanks... J Hi Peter, You're correct. You can choose the buffer offsets when you call Allocate.... however, I do not want to call Allocate (and have to redraw the buffer), every time I ...Show All
