• Visual Basic Cross thread call error

  I am using VB.NET 2005 I have the following application structure: UI form, a middle layer and a low level layer. They are all running in the same thread. The low-level object creates a serial port (the .NET one): New SerialPort(port, 57600, Parity.None, 8, StopBits.One) and handle its events. Some of these event handlers throw events that are handled by the middle layer that in turn throw events that are handled by the UI. The serial port is running on a different thread than the application and hence the event handlers are not running within the low level's thread. The end result of the chain of events mentioned a ...Show All

• Visual Basic Add connection wizard fails with Access database

  I have the RTM version installed. I am quite puzzled at this wizard. It works fine with SqlClient. But for Access databases, this wizard completely fails. In this wizard, I only have one option to do - setting the ConnectionString. I set it to Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\path\abc.mdb, which works fine in my code. But when I click OK, it complains: --------------------------- Microsoft Visual Studio --------------------------- Format of the initialization string does not conform to specification starting at index 0. --------------------------- OK   --------------------------- And more, the Advanced button is dis ...Show All

• .NET Development Updates are not written to the database - please tell me why!

  I am at my wits end! I am creating a simple web application in Visual C# 2005 Express Edition Beta 2 by dragging a table from a data source onto a windows form. I have reread numerous articles on MSDN but with the exception of adding a try block this is as far as I can tell all I need to do to create a working form. When I run it all looks good, I can edit fields and click on the save (disk) icon. But when I look in the database again - it is unchanged. No exceptions are thrown. As far as I can tell from stepping through the code it is doing everything that it should - except that the update method   ...DataObjectMethodAttribute(...Dat ...Show All

• Smart Device Development WinCE C# project: Menu occupies too much space

  I have a menu in my C# NETCF 2.0 application. There are only 2 menu items in the top row. If I put a label beside them it's invisible, blocked by the menu eventhough the area is free. The menu seems to occupy a standard area no matter how many top menu items there are in the menu. Is there any way of making a menu occupy only 30 % of the top row instead of 80 % (what it seems to be right now) A device my company manufactures themselves. It runs Windows CE 5.0 and NETCF 2.0.

• Visual Studio Express Editions Help Uninstalling Please

  Hi All Earlier this month I downloaded WD, VB Express, the .NET Framework amd associated files. I now have decided this is not for me at this time and started uninstalling various components via Add/Remove to free up some valuable space. When I reached SQL Server I found I coudn't uninstall and I inadvertemtly removed the component from Add/Removes list. How can I add it back to the list and more importantly how do I then uninstall when it's back in Add/Remove's list. All the other components uninstalled fine. Cheers!

• Windows Forms Setting DataGridView.DataSource = null erases the columns I set up in design mode

  Based on the user's selection in a combo box, I want to update the contents of a DataGridView from a stored procedure. So I set its DataSource = the DataTable that has the data. The user can also have nothing selected in the combo box (SelectedIndex == -1). In this case the DataGridView should be empty. So here I set the DataSource = null. The problem is that after I set the DataSource = null, I lose the columns that I had set up in design mode and can't get them back. What is the "correct" way to do this so I don't lose the columns Presuming that you are always binding to the same D ...Show All
