.net - Display Related Data In A Datagridviewtextboxcolumn?
Jan 1, 2011I have a datagridview bound to a bindingsource. Two of the columns contain values that link to the primary keys in other tables. Instead of displaying the primary key values, I would like to display the name of the item associated with the primary key. In other words, the primary key value may be 3 but I want to display "Furnace 5" in the datagridview instead of 3 (which it is now displaying).

VS 2008 Disable Text Boxes Until Combo Box Choice Is Made?
May 28, 2009I currently have my cute little first program made... I'm just stepping into the water with this programming thing. I made a program where you can select a shape from a drop-down list and then input some values and click a button and get the area of the shape. I have it working so that when a certain shape is chosen, certain fields are disabled, such as when you pick "circle" from the combo box, the "length", "width", and "number of sides" text boxes are disabled but the "radius" text box is enabled, thus allowing you to enter the radius and find the area. I want to make it so that when you first load the program, all of the text boxes for the length, width, number of sides and radius are disabled until you select a shape from the list. Currently I'm using

This works for disabling the correct boxes when something is selected, but I don't know if I'm even on the right path with that first part.

Jun 6, 2011I'm making a system where only the supervisors can use the Ctrl+Alt+Del to bring up the menu (Vista / Windows 7) or start taskmanager (XP)Since my application will not be running on anything less than XP I don't need to worry about 95, 98, ME, 2000, etc. I have this code so far (found on here and a little edit by me) but the Ctrl + Alt + Del doesn't get stopped like I thought it would.
Note to use this from within Visual Studio you might have to untick the box for "Enable the Visual Studio hosting proccess". In VS 2010 it is found in Solution Explorer > My Project > Debug > Enable Debugers > Enable the Visual Studio hosting proccess I've found several ways to stop taskmanager loading but not to stop the menu being displayed. This code is working except for my little problem with the Ctrl Alt Del menu and has been tested by me with VS 2010 .NET4 on Windows 7

Jul 28, 2010I have a VB.net program that is developing a Word Document with a table of contents based on values in a SQL database. This works just fine. The issue I am running into is that I do not have control of the Office/Word environment. Some users have add-ins installed in their instance of MS Word. An example would be a PDF writer. Another example is a tool to put the document in a Document Management system. I am finding that some of these add-ins are slow to start and others do not shut down well. What I'd like to do is instantiate my MS Word application without running any installed add-ins.
