I have several ComboBoxes which have a string "(null)" added as the first item and then the rest of the list is populated from a List (of strongly-typed classes).
When I try and set the SelectedItem (or SelectedIndex) property, internally it is selected but it's not updating the UI. E.g.
if (itemToLoad == null)
{
comboBox.SelectedItem = "(null)";
}
else
{
comboBox.SelectedItem = itemToLoad;
}
Now if in the debugger (or later on in the code) the SelectedItem is queried it shows that comboBox has the correct item selected but it has not changed the text in comboBox to reflect the change.
Any ideas on why this is happening and/or how to fix it?

Never mind, it was application specific code which was doing this.

Is there a good tutorial somewhere on Setup projects?
I can manage adding files and putting them in the right directory, but also want to show some extra info, perform command line commands and execute some sql statements (changing or updating tables, ...).
Also being able to provide some choices (which language etc) and creating a config file would be nice.
I don't have a good idea where to start with this stuff.
tnx for the info !
I've found a living worth working for, but I haven't found work worth living for.

Hi,
I don't know if the setup projects available in Visual Studio will allow you to do something like what you want. You could try to use this

Use Double.TryParse or DateTime.TryParse.

hi,
i checked the way you suggested,
it worked with double.tryparse but there is no such option like datetime.tryparse.
please check this out.
thanks.
Nitin.

There is a DateTime.TryParse method! It's new with the Framework 2.0 but as you found double.TryParse you're clearly using this version. Maybe you misspelled.

You don't know which .NET version you are using? Huh?
Well if you can't use it, then you have .NET 1.1, otherwise .NET 2.0.
But you can also use DateTime.Parse() and catch the exception

Hi,
Use the try catch block !
try
{
DateTime.Parse(textBox1.Text)
// code if it is date !
}
catch(Exception ex)
{
//error code
}

Does your application need the default setup package ? means you can directly do the copy and run the program exe ? Is it possible in ur case ?

Hi,
Can you create your own setup application ? This app wont have any GUI and would only register the required dll's. You will run the new application instead of the default setup package.
I actually dont know the complete scenario on your side, thats why i can just guess and ask questions !

Hi,
I am trying to use a VB ocx control in C#.
I have done the following
1. Registered the ocx
2. Included the component in VS .Net IDE tool bar.
But when I try to drag and drop the control I am getting an error "Failed to import the ActiveX control. Please ensure it is registered properly."
Any idea why this is happening?
Note:
Internally the ocx control makes use of a C++ dll.
I am using .Net Visual Studio 2005
