• Windows Forms DataGridView Columns Reflecting User's Checkbox Choices

  Hi everyone, First off, I am able to reflect the user's dropdown box selections.  These selections act as the "where" clause in the select statement.  However, the problem I'm currently facing is having the DataGridView columns reflect the user's choices with checkboxes (which are not on the DataGridView).  In other words, I would like the user to determine whether or not a field is shown in the DataGridView.   This means that if the user checks the Account checkbox, for example, then the select statement should show up as select Account from datasource where ... group by Account Further, in the ...Show All

• Windows Forms list box tooltip?

  Hi. Is it possible on a WinForm C# application to have a tooltip appear under the mouse cursor when you hover over an item in a listbox I am using .NET 2.0 Yes you can but it requires a little bit more work than using something like a ListView.  You'll first need to drop a ToolTip component onto the parent form.  This gives your ListBox tool tip capability.  Then you'll need to trap the MouseMove event on your list box.  Whenever this event occurs you should get the index of the item at the current position of the mouse.  If you get an item then you can use whatever logic is appropriate to determine the tool t ...Show All

• Visual Studio Tools for Office VSTO deployment – light solution.

  Here is a good question to get people thinking Is there an easy way of deploying a VSTO solution without having to install all the prerequisites (just the min comp. and spend 10 min max per pc  ) Imagine the solution needs to be exported to 100 users – it takes time to install all the prerequisites and Office components. So there has to be a way of getting a VSTO solution to run without spending a lot of time at installing all the prerequisites and spending a fortune at getting licenses for Office.

• Windows Forms ContextMenuStrip has an offset when application is running in full screen mode

  Hi, I have an application running in full screen mode. The main form contains a ContextMenuStrip that is shown when the user clicks on the form. There is an offset between the location where the context menu appears and where it should appear. Here’s the problem. I hope someone can give me a workaround. In order to compute the location of the context menu, the working area is taken into account, even if the application is running in full screen mode. If the location where the user clicked falls in a region that is outside of the working area, the context menu automatically offset its position so it is displayed in th ...Show All

• Visual Basic Selection rubber band on forms larger then 800 x 600

  Has anyone noticed that in the 2005 vb ide that the selection rubber banding hides when moving past the 800 x 600 boundary on a large form Items are still selected correctly. This was not a problem in 2003. Sure enough! My normal resolution is 1600 x 1200; when I bumped this down to 1024 x 768, the rubber-band disappeared in the y-direction. If you file this bug at http://lab.msdn.microsoft.com/productfeedback/ , we'll make sure that the forms designer team sees it (and you'll be able to get feedback on it from them). Thanks for the report! --Matt--* ...Show All

• Visual Basic oledb vs sqlclient data adapter performance when running in ide

  I have a fairly wide table on a MS Sql server 2000 server. Pulling about 6000 rows using a the oledb namespace in the ide takes about 6 seconds. Using the sqlclient namespace it takes about 0.3 seconds. When run outside of the ide, the sqlclient takes about 0.2 seconds and the oledb takes about 0.3 seconds. Why the huge increase for the oledb namespace I'm using a 3rd party assembly for some data access. They use the oledb namespace because not all of their clients run MS Sql servers. I'd rather use the sqlclient, especially with this massive oledb slowdown, but I can't. Can you provide any insight into this Is there anything I can do to i ...Show All

• .NET Development ServicedComponent RegistrationException - Invalid Derived Classes

  I am having difficulty with code that used to work in 1.1 working in 2.0. I have an n-tier application that uses ServicedComponents for persisting database information within a single transaction. Because I want these classes to be able to participate in transactions, I derive them from System.EnterpriseServices.ServicedComponent. In 1.1, this worked just fine, however in 2.0, when remoting these components using .NET remoting over TCP, I recieve a RegistrationException stating that: Invalid ServicedComponent-derived classes were found in the assembly.
