I came across the same problem today with the XMLSerialiser... But in an attempt to deserialise the object (in my case quite complex) failed...

1. (The probably ridiculous question Can a Panel be on one thread, and it's parent Form be on another?
2. I want my app to have two threads- main and worker. How do I stop the worker thread from ending while its waiting for stuff to do? Do I actually have to make some kind of hackish while(true) loop while it's waiting for something to do. If I do that, and then the main Thread calls one of the workers's functions via a delegate, then how do I make it escape the while loop to do it's work?
I mean, the main thread in a normal app doesn't need anything like that in it, it just stays alive waiting for events until the user exits the app. Its not like we do void Main{while(true) listenforevents();} you what I mean? Is there a Thread.ListenForEvents=true so that it won't die?

Not really answered but more of a description to the problem! I sat with this for ages (2 - 3 weeks) when I started C#. The solution is to invoke the method than rather calling it directly. Then this opertion is perfectly allowable!

Changing the opacity of a MDI child form has no effect.
If I change the opacity of the MDI parent, then the child's opacity changes too.
What I want to do is change the child's opacity independent of the parent's.
Is this possible?
Or, maybe the child form is considered a "control" of the parent and then inherits some characteristics from it.
Cheers,
Simon

Hello Friends,
I am trying to create an installer for my application which will check if the .NET Framework is
installed on the user machine. If the framework is not installed then I want my installer to
first install the framework and then install my application.And if the frameWork is installed it
should directly install my application escaping installing .NET Framework.
I have developed the installer using the procedure given in msdn "Redistributing Dotnetfx.exe
using Setup.exe Bootstrapper".
My installer folder, which is right now on my local m/c having path D:\\Installer, contains
following files...
1)mySetup.msi
2)setup.exe
3)settings.ini
4)dotNetFrameWork/dotnetfx.exe
My setting file looks like this
[Bootstrap]
Msi=mySetUp.msi
'LanguageDirectory=
'ProductName=testproductname
'DialogText=
'CaptionText=
'ErrorCaptionText=
FxInstallerPath=dotNetFramework\
now when i try to open/run setup.exe its giving me following error :
"Incorrect command line parameters".
I've tried using :
FxInstallerPath=D:\\Installer\dotNetFramework\
But still getting the same problem.
Can anyone tell me whats the problem.
Thanks in advance.
regards,
Saroj

Hi.
I have some fundamental questions on the listview.
1) I added a listview with some columns, however, the column titles do not appear. The columns are there, but they do not appear. Is there a setting in winform that can hide it?
2) How do you search for an item in the listview?
3) How do you set the text of a specific item in a listview? For example, I want to set the text of item 2 column 1.
Thanks,
Kuphryn

You need to be on Detail mode instead of Small Icons, Large Icons, or List.

Well, you would do something like this: myListView.Items.IndexOf(myListViewItem); where myListViewItem is the ListViewItem that you want.

myListView.Items[0].SubItems[0].Text = "This text appears in the first row under the second column!"
Hope that helps.

Nice!!! Thanks.
One last question on this item. How do you determine exactly what item the user selects via mouse?
For example, let say I click on item 2, I want the program to do something with item 2.

Then you would use the myListView.SelectedItems or myListView.SelectedIndices property instead of myListView.Items
By the way, there are some really cool replacements for the standard list view. Consider this one for your app instead. Carlos really does a good job on custom controls. He also explains what's wrong with the standard one and why he implemented the new features that he did.

Okay. Thanks.
I tried using SelectedItems, but it does not return the correct selected item. For example, it always return index 0 even if I select index 10.
Kuphryn

Are you handling the SelectedIndexChanged event? And, since SelectedItems is a collection, did you access it like this: myListView.SelectedItems[0]

-Chris Maunder

Yes. I added a handler for SelectedIndexChanged event and checked SelectedItems[...]. However, for some reason item 0 is always selected even if I click on item 2002. Weird!
Kuphryn
|
|
|
|
|
Actually, I just played around with it a bit, and you should handle the click event instead. Then do myListView.SelectedItems[0]. Oh, and you have to use 0 because that's the only item in the collection of selected items.

It is not an application. It is something I have to do for a school project. Thus, I do not consider it an application. Lets just say it is a "Hello World" instruction using C#.
Thanks again,
