Hi again

This one sounds hard and not even !!!google!!! OMFG gave me an answer since I cannot phrase it so google understands the question.

When I click on a node in a treeview, how would I make it so that a panal or groupbox nearby will show the options for that selected node?

You are my last hope since I cant get google or MSDN to cough up any results.

The tree control has an event when the selected node is changed. You catch that, work out what node is selected, and show your contents accordingly.

I was going to suggest something like that. Is there a way the OP could data bind the selected node to the panel/groupbox?

I don't believe the nodes themselves have events, no. Having one event call different methods based onthe node selected seems nicer to me, anyhow.

Okay. Was just wondering if there were more than one way of doing this. Your solution sounds quick and easy Big Grin | :-D

Um guys I still need help?!?!?? What event.. Catch?.. event..? Confused | :confused:

Can someone give me a code snippet because I'm the type of person that learns how to code from code snippets and then experiments with it. I am stuck here with a tree view and a panel thats not doing anything....

Many thanks

Try using the NodeDoubleClick event procedure ...

Private Sub TreeView1_NodeMouseDoubleClick( .... ) Handles TreeView1.NodeMouseDoubleClick<br />
    GroupBox1.Text = TreeView1.SelectedNode.Text<br />
End Sub

What am I looking for in the properties panel? (sorry about this I'm just real tired and my eyes are fuzzy)

ugh... what have i gotta change in the properties panel? Is it that tag field or is it something in the node properties somewhere?

Yes. Because I did Roll eyes | :rolleyes:

For the Treeview, under Events icon, there should be one called NodeMouseDoubleClick, use that one...

THANK YOU I LOVE YOU!!!! LOL (sorry thats not normally me)

Anyway, since I have done that, will it now make it so that the group box will show the properties just for the node I have clicked on and then when I click on another node it should clear the properties of the last one and then show this new nodes properties? (sorry if thats a bit confusing)

EDIT

Damn.. I just ran into a new prob In editing mode I cant select nodes so how can I make the properties for each node in 1 group box :S Sigh | :sigh:

EDIT 2

Damn.. again, I just relised that just changes the group box text not whats in the group box.. how do I change whats in the group box :S.. my god this thread is getting big.... SORRY EVERYBODY

Just apply whatever changes you want to the controls in the group box based on the node that is selected...

Put in a value in the Tag property for each node, so when the NodeMouseDoubleClick event is triggered, you know which node the user double clicked.

Thanks!

Just one more thing im not sure about? when I click on the next node, the controls from the old node are still showing, cant I make it so that when the new node is double clicked the old nodes properties dissapear and the new nodes properties appear?

E.g

First node has a text box and a combo box in the group box and then when i double click another node the group box hides the textbox and combo box and then displays just a list box (or whatever)

I would like to calculate a mathematical function like sin, log, exp or something else as an array and than draw a diagram from this array. Someone told me that I would need a Chart Control, but in the toolbox of my version of VB 2005 express I cannot find such a control.
Where can I get such a control and the information how to use it?

Christian Graus26-Nov-06 11:20

There's no chart control included in the framework. You can draw it yourself, or search the web for a third party component.

Hello guys
I m reading from a text file, and in the same time comparing the read value with predefined values in a DB
From file:
EXTERNAL ALARM
GENERATOR RUNNING KAA
EDL ARSAL FAILURE

Having KAA in my database I want to retrieve the ID of this data
And having ARSAL in my database I want to retrieve the ID of this data

This is a part of my code,
I know that this code sounds erroneous,

Do While Not sr.Peek = -1<br />
            checkStr = sr.ReadLine<br />
cmd.CommandText =select ID from table  where name like '%" checkstr & "'"<br />
end while<br />

I guess the prob is in “%”,
Thx for your help

Regards
Ramy

I could be wrong, but this looks like it should read

cmd.CommandText ="select ID from table where name like '%" & checkstr & "'"

As the lines that you read contains several words, and the data in the database is single words, you should look for the word in the string, instead of the opposite:

cmd.CommandText =select ID from table where '" & checkstr & "' like '%'+name+'%'"

b { font-weight: normal; }

Not
