• Learning VB VB.NET HELP!!!! Login Page HELP PLEASE!!!!!

  Hey everyone. I got the basic LoginForm in VB.net to work for me but I wanted to slightly modify it. I added a dropdownbox for the user to select whether they were a "User" or "Administrator". I have an MS Access database called AITP.mdb with only one table in it called user . The user table has the following fields with attributes in parenthesis: user_id(autonumber), user_fname(text), user_lname(text), user_login_name(text), user_login_password(text), admin(Yes/No), user(Yes/No). I want the prog to check what the user entered as an accesslevel, on the loginform, against what they have in the database. For example if a user has both admin and user then the form that opens depends on whether they selected adminis ...Show All

• katti205961 System.InvalidOperationException when creating a form. How do I debug the form.show() method?

  An unhandled exception of type 'System.InvalidOperationException' occurred in Program1.exe Additional information: An error occurred creating the form. See Exception.InnerException for details. The error is: Control array element 2 doesn't exist. I put a breakpoint on the form.show() method, but I still get this error. I am assuming it's related to some control on the form, but there are no details. I'd like to trace or debug the form.show process if possible to determine which of the 100+ controls is causing this error. This application is being converted from VB6 to VB.net and it works fine of course in VB6. How can I trace into the form.show routine provided by the System.Windows.Forms framework to find out which control i ...Show All

• Paulustrious How can I check the Internet connection speed via code?

  How can I check the connection speed by code. Thank you Nofal First, get the NetworkInterface that is connected to the internet. Check for the right one when you get them all -- in the example: zAllNICs variable-array stores all the networkinterfaces, I'm assuming Item 0 ( Private theNIC As NetworkInterface = zAllNICs(0) ) is the right one, but that will not always work. Once you have the right NetworkInterface, you can check its properties to see how many bytes in total have been received/sent. If you put some time-points around that in code, you can calculate the speed in bytes per second (or whatever units you want). Here's a (hopefully) working example, but note that I scrambled it together from my own speedgraph ...Show All

• 2162 2003 > 2005 Upgrade problem

  I have an application written in VB.Net '03 that worked fine until I attempted an upgrade. I have most of the bugs ironed out, but one I can't find a solution to: My buttons light up on MouseHover, and "unlight" on MouseLeave. This is true of all buttons, including the "exit" button. The problem is, after I click the "exit" button, the Windows Form Designer Generated Code "dispose" sub triggers the MouseLeave event, which generates an "ArgumentOutOfRange Exception because the collection the "unlit" Exit Button image is stored in is no longer available. Yikes! This didn't happen in '03 -- how do I sidestep it in '05 Is there a way to say "If the last button clicked was NOT & ...Show All

• rooooooodog Inconsistent Operation between OS/PC's

  Hi all, I've written a small application, that consists of a text label, a gif image and a button, which is compiled into an executable image. On button press, the following callback code is executed to try and determine the domain name of the host computer. However, depending on what computer I run the application upon, I see different results. On some PCs, the routine runs correctly and the domain is printed to the screen. On other PCs, the application launches but the domain name fails to be printed. Finally, on some PC's the application fails to launch, and an error message is displayed. I'm wondering if any of my code maybe OS/machine dependent Or, perhaps, maybe there is an issue with the handling of the gif imag ...Show All
