If the node to be deleted has children you have to move one of the children up and rebalance the other children into the the other child. Draw a picture, it helps.

"Sir I exist!"
"However," replied the Universe, "The fact has not created in me A sense of obligation."

i know how to delete but i don't know write it by C#. Because i don't know what method that delete node, for example,
//assign node that want to delete to TempNode
TempNode = NodeDelete;
//how to delete TempNode
//it's problem with me

You need to register your com object, with regsvr32. browse to the folder the dll is in ( in a command window ) and type regsvr32 dllname.dll
It may need a command switch, but I don't think so, I think registering is the default.

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 !

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.

|
|

hi,
thanks for the link. it suggest that DateTime.TryParse exits.
but dont know which version of .net m using i cant find DateTime.TryParse.
i ll hv to check the version.
thanks

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
}
