Developing A Small Application Using VS2008, The Mdiparent Has A Expandable Panel With Button?
Feb 15, 2011
I am developing a small application using VS2008, the mdiparent has a expandable panel with Button 1 and Button 2 on it, which opens up child form 1 and child form 2. ( The two child forms are maximized within the mdiparent form)
The problem is, button 1 opens child form 1 and button 2 - child form 2. I cant open the two forms randomly. I have to close the topmost form to access the other forms below it and vice versa.

Form1 is a mdi container. It has a bunch of forms that can load inside of it as mdi children. If I close each open form inside the form1, and then click the red X at the top right, application exits fine.If I click the red X without closing the forms inside I get: An unhandled exception of type 'System.CannotUnloadAppDomainException' occurred in mscorlib.dll
Additional information: Error while unloading appdomain. (Exception from HRESULT: 0x80131015) However I can break from it. How do I get the application to not show that error? What must I do to fix those inside forms or close when the red x is clicked?

I have developed a small application. It has a MDIParent form on which the other childforms are displayed. I have a Panel on the MDIParent on which there are buttons to call up the MDIChild forms. Now my issue is, when anyone of the buttons on the MDIParents form Panel are clicked, it should check if another Childform is display, if it is then it (the active childform is closed) and the new form will be displayed. This part is working fine from the code below. However, when there are no active MDIChild form on the MDIParent form and if the button is clicked, the 'Else' part of my code below is executed. This generates the error as 'Object reference not set to an instance of an object'. So what is wrong with my code below?
Private Sub btnExecutive_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecutive.Click
Dim MDIChildForm As New frmExecutiveInfo

I have trying to do an elevator simulator, wich have to includo the panel with the floor, available floors, and a button panel with available floors and button up, down, but I dont understand is how to use the timers for up and down, because I vague idea to select the floors is to usea a for or select case but I dont know wich one is the most appropiate in this case. Wha tI have so far is:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Timer2.Enabled = False
If lbl1.Text = "4" Then
lbl1.Text = "1"
[CODE]...
This just shows the levels and the timer1 just go up and a little "screen" shows at what floors is the elevator but this just go up and start from one again.

I'm doing the first bit of web-page development I've done in years, in VS2008, using VB.net. I have a fairly simple layout, which is using several nested tables. IE6 displays the layout just fine, but Firefox for some reason shows the whole thing in a small panel at the top of the page, with a scrollbar.

I am in the process of developing a messaging framework for a windows application that sends messages to a java application. To be precise when the win app wants to send a message it simply drops the message in a common database table which will be picked up by the java app. The windows application is deployed across 10 application servers (10 instances) over citrix for load balancing.Each instance of the application is capable of sending a message to the java application and each of these messages should have a unique id. From my end I need to make sure every message generated has to carry a unique id so that they can be identified when necessary. All the messages can be cleared every day or two.i am not quite sure about a best method of achieving this. Initially I wanted to create a static method that serves the next available id (incrementing the last id by 1). But this approach willn't guarantee unique number as the application starts only when at least one user is logged on. For e.g .On one server the app starts when a user logs in, he then sends a message and then the application stops when that user logs off. So when a next request for the app comes to that server a new instance will be started.

I am trying to develop a chat application using Visual Basic 2008. I have referred some articles on the internet like [URL]...rogramming.htm and got the concept of connecting and sending data. But when it comes to real world chat applications, there is user authentication and all that. So I was wondering if it is possible to make my own Windows Live Messenger or Yahoo Messenger!!. I searched web for such a sample or source code, but could not find any. Has anyone here created such an application??

I am developing an application using VB.Net which is a simple executable which is to be run from a network drive of our company servers. Most users can access this executable without issue - others however can open the executable but have no connection to our database (even though when running the executable off a local drive such as C:, the database works no problem).
From some posts I have seen this might be a CAS issue - however our IT department suggest the issue might be down to different version of the .NET Framework being to blame. Firstly, is this the issue? Secondly, how can I develop my application to work with different versions of the .NET Framework? Surely this doesn't mean developing many different executables?

I'm trying to setup sort of a LAN keep-alive proxy...Ex.: My Xbox 360 is connected strait to my computer via an ethernet cable. My computer is connected to the internet via a Wi-Fi adapter. Everything works fine and I can access the internet on the Xbox and computer.
Issue: Every time I start my Xbox I have to set up a "Home or Small Office Network" via the control panel to access the internet. What I would like to do is implement a proxy that when I shutdown the Xbox the LAN doesn't give the "Network Cable Unplugged" notification. I wasn't sure if there was a way to make the connection stay open for so long after it should say unplugged. Such as if I need to restart the system and don't want to have to re-setup the network on the computer.
This is my code to retrieve the network info:
Imports System.Net
Imports System.Net.NetworkInformation
Module Module1

I am looking for a contol either listbox or listview to support my requirements. Basically how my application looks is:
[Code]....
Having said these things. I used to program in VC++6, VB6. But using those version now seems not realistic now as I lost touch. But if I have to use the latest 2008 versions, for which I do not have any experience seems scary. So, If you are reading this , and you have got some experience in these fields or using controls that support my requirement, can you please let me know which programming language or IDE and Control should I use to develop this application. PS: the image is made using mspaint and does not represent actual program.

I'm about to start a new project and want some advice on how to implement.I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out.
If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules.to make things more difficult, there is some shared functionality like common users, roles and security.Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional.Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame.I can see that say, if I wanted to update the time management module,
