• Windows Forms C# Combobox ValueMember problem

  Hi all, I'm pretty new to the world of C# and .Net and enjoying it so far. I'm having trouble setting the index value in a combobox. I'm using MySQL connector/Net and because it doesn't provide certain tools/extensions to work with Visual Studio I have to do certain things manually (which isn't  problem because it helps me understand C# and .Net better). :^) My original intention was to take names and ids from a table and use the id as the index in the combobox list and the names as display. I get a full list of the names no problems. But the index is always the same, integers incremented with each item. As you can see I've tried crea ...Show All

• Visual C# Date Validation on a Databound Textbox

  Friends, I am curious if anyone knows a way to pop a validation messagebox based on what is already taking place in a date bound textbox in Visual Studio 2005. What I mean is this...... Yes, I can write a routine to run through the characters and check if it is a valid date but the textbox (and/or bound dataset ) seems to be doing its own validation. If I do not type in a valid date using a /, ., or -, the form simply will not let me advance to the next record using the navigator, which tells me that the textbox or dataset is doing it's own validation WITHOUT me having to write a whole new method to do it. I even checked an invalid lea ...Show All

• Visual Studio Express Editions color coding vs black&white appearance of .vbs file

  Hi, I was using MS Visual Web Developer to edit a .vbs file, and it appeared with line numbers and color coding for the various components. I just installed Visual Basic 2005 Express, and when I open that (or any) .vbs file, it appears in black and white. Any idea how to get the color coding back Thanks! Nevermind, I had to associate .vbs files in the Tools-->Options-->Text Editor-->File Extensions. A follow up question though, the icons to comment out selected lines are greyed out. (But not if I use the MS Visual Web Developer version). Not sure if this means there are even other fe ...Show All
