    In the properties of a listbox, under "Behavior" there is a property for "horizontalscrollbar". Is that what you're looking for or are you having problems with it?

    Pre-JIT

    My guess is that not every object needs to be compiled to binary pre-run. I have a few class libraries that house alot of my data access functionality. All of my different apps reference those dll's, but I didn't make one for every database. If the JIT compiler compiled every object in that...

    Dont Understand Classes.

    You actually have to instantiate the type as 'new' and you can run it as many times as you feel like. Each time it will create a new instance of the object on the heap and change/add the reference on the stack. This creates a reference on the stack: public example as class1 This is the...

    Dont Understand Classes.

    Good example. I just would like to clear up a couple things. Although it's not necessary, properties still should have a scope associated. Anything that can have a scope, should have a scope. Also, they normally "return aAge" instead of working like a function. The 'New' doesn't need to...

    getting pwds for a particulat username

    Since we're being purists in this thread (not a bad thing :)), I thought I'd just throw this in. Hashed values have been proven to collide. And now with rainbow cracking, it's going to become more and more common. A simple MD5 or SHA-1 won't be enough. You're going to need to add a little...

    Dont Understand Classes.

    Classes/Structures are the backbone of .Net. Here's a quick overview followed by some good references: Classes are reference types. On instantiation (when the constructor 'new' is run), they are created in the heap and a pointer is placed on the stack referencing them. These are for heavy...

    Structure Tree Dynamically from XML

    Treeviews are always a nice way to display XML files. Side Note: (My opinions the same for vbforums.com also)

    Need help setting up a form

    You might not want to mention it as "a loss of flexibility," but sell it as "a more concrete business process." I was in your position earlier this year. I came to a company with no other developers, but they had scattered access applications that independant contractors had been building for...

    help needed about datagrid

    It happens because you used databinding. Easy solution is to change your SQL query to something like "SELECT FNAME as [First Name], LNAME as [Last Name]..." It can potentially get ugly with joins.
