    VS 2013 Re: Sorting controls in FlowLayoutPanel

    This is not an answer to your question but you're handling the wrong event. With the code you have, what's going to happen if the user opens the drop-down list and then uses the arrow keys to select...

    Re: Using vbYesNo in MsgBox

    MsgBox is a function and it returns a value to indicate which option the user selected. You use an If statement to test that value and act accordingly.

  6. Re: VB.Net not configured to read SQL Server Directly

    I'm guessing that you're using VB/VS Express, which I think you'll find can only generate a Data Source from a local SQL Server Express file. You'd need the Community Edition or a paid-for edition...

    Hang on! I just noticed this:Are you using Outlook Automation? That's probably the sort of detail that you should mention.

  9. Re: I am getting a form related issue in my software.

    Can you show us your MW.Upload and FTP.Do_FTP methods? My guess would be that you're trying to create a default instance on a secondary thread that has finished its work.

    When the grid itself is editable, are you making cells read-only directly or via their row or column?
  11. Re: Clients not receiving Response from Server

    I don't really see how using a BackgroundWorker is any safer. Either way, you need to avoid accessing controls on a secondary thread. If you can't even identify where you're doing that now then I...
  12. Re: Clients not receiving Response from Server

    It's obviously not there because there's no control access there. It must be somewhere else. Did you look at the exception when it was thrown in the debugger? That should tell you where the issue...

    Do paired ins and outs have to occur on the same day?

    Re: need advice on table structure

    Presumably the first time is in and then they are considered to be alternate. That would mean that, with a zero-based index, even-numbered records are in times and odd-numbered records are out times.

    A cross-threading error occurs when you try to access a member of a control on a thread other than the one on which that control was created. It's not strictly illegal, which is why is allowed to be...

    There's something wrong with your namespace imports too, so I'm guessing that you haven't referenced a required assembly. If you mouse over one of those underlined imports, what's the error message...

    Argh! Are we being punked? Do not - I repeat, DO NOT - create a new DataTable or DataSet. Just pass what you already have. Instead of this:

  25. Re: Looking for a faster file write routine

    That's a very unnecessarily comvoluted method. All you need to do is prepare the text you want to write, either as a single String or a String array, and then call File.AppendAllText or...

    Re: Store images

    Hmmm... I'm sure I've tested that before and it didn't work. I don't think I used a typed DataSet as the data source though, so maybe that's the difference. I might look into that to satisfy my own...

    So, are you saying that you want a column for each subject and a row for each student and then each cell will contain that student's mark for that subject? If so then you would have two choices:
  30. VS 2013 Re: [RESOLVED] Convert hex string to byte array and restore image

    Everything is stored as bytes. If the binary data was converted to text of any kind then, in order to store that text, it would have to be converted to bytes to be stored. In that case, instead of...
  31. VS 2013 Re: [RESOLVED] Convert hex string to byte array and restore image

    I see what you're saying now. That's just because hexadecimal is the usual way to visualise binary data. The data has to be converted to a string of some sort for display. You can't actually view...

    That doesn't work. The data is retrieved from the database as a Byte array and, while a DataGridViewImageColumn can convert that to an Image object automatically, a PictureBox cannot. You'd have to...

    The List(Of T).ToArray method creates a 1D array. There's also another serious flaw in your code that I won't go into now because I believe it will become a moot point.
