Jan 4, 2010We have here visual basic/studio 2003 running in my XP box and I need to install MSXML so I can use MSXML2. I went to the microsoft site and got msxml 4 (code uses that version).

VS2003.Net Project To Read XML .config File And Modify?
Mar 26, 2009Dear Friends: I have some files in 1 folder directory that show "XML Configuration File" under type. But none of these files show the extension .config. The directory filesare like C0150,C0150_new,C0200,C0200_new etc. I need to change only 1 attribute of each of these files. I need to write a VS.Net project to do this. I have to send the .exe file(from bin directory of this VS.Net project) to my client and they will just double click the .exe file and it will change that attribute in all the .config files.
The C0150 file looks like this:
<?xml version="1.0" encoding="utf-8"?>

.net - RaiseEvent From A UserControl That's Placed On A UserControl That's On A Form?
Jul 11, 2011I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.

Setting Usercontrol Properties Within A Usercontrol
Mar 22, 2012I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control. If I create a reference to the usercontrol form the second form within the usercontrol I get a new instance of a user control. All I want to do is set the property on the usercontrol and close the secondary form. How do I reference the usercontrol from the form within the usercontrol?
Code in UserControl:
Public Property DBItems() As List(Of String)
Get
Return DBItems

VS 2010 Load Data Into UserControl In UserControl.Load?
Sep 25, 2011I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.

.net - Dispose Of A Task?
May 13, 2011I am having fun working with System.Threading.Tasks. Many of the code samples I see, however, look something like so:
Dim lcTask = Task.Factory.StartNew(Sub() DoSomeWork())
Dim lcTaskLong = Task.Factory.StartNew(Sub() DoSomeWork(), TaskCreationOptions.LongRunning)
Task.WaitAll(lcTask, lcTaskLong)
That's the extent of the sample.Tasks implement IDisposable, so obviously I'm supposed to dispose of them, but what if I just want to "Fire and Forget"?If I don't dispose, will I leak threads/handles/memory/karma?Am I using tasks "wrong"? (Should just use a delegate and leave tasks alone?)

Appropriate Use Of Dispose Method
Jan 28, 2009When is it appropriate to apply the dispose method to controls?For example in a form that has five group boxes, once the first group box is used to gather user entries and is no longer needed, is it worth it to apply the dispose method to the first group box? Is it needed for local variables, for example a StringBuilder used within a private function which is only used while the function is executing?

Does The .dispose() Method Do Anything At All
Jan 7, 2010I was experimenting with ways to get rid of some memory leaks within my application the other day when I realized that I know virtually nothing about cleaning up my resources. I did some research, and hoped that just calling the .dispose() would solve all of my problems. We have a table in our database that contains about 65,000 records. Obviously when I fill my dataset from the dataadapter, the memory usage can get pretty high. When I called the dispose method on the dataset, I was surprised to find out that NONE of the memory got released.

Call Dispose With Regions?
Jun 22, 2011When you set a region equal to another, or set it equal to a new instance, do you have to call dispose on the region, or does VB do that? (I guess this isn't necessarily specific to regions)
ex:
'at some point in the code a region is created
Dim Rgn as New Region(SomeRect)
'....
[Code].....
If Rgn now points to the Rgns(0) clone, what happens to the original memory created by "New Region(SomeRect)"? Do I need to call dispose on Rgn before assigning it to the the Rgns(0) clone?
