Not true all of the time... sometimes it is used as the "alpha" channel to convey translucency. But probably not in his case.
He said, "Boy I'm just old and lonely,
But thank you for your concern,
Here's wishing you a Happy New Year."
I wished him one back in return.

Hi Everyone,
I need to change the forecolor to Red and backcolor to blue when a node is selected in a treeview. Can anyone help me in this regard.

Handle NodeMouseClick event. You will get the node selected by checking TreeNodeMouseClickEventArgs.Node . TreeNode has BackColor and ForeColor properties.
Reading the documentation is always a good practice

Hi Navaneeth,
Thanks for your response. Iam using VS2003 IDE. "NodeMouseClick" is not available. Please let me know how to proceed.

I tried with "Treeview_AfterSelect", color change is not happening.

Here is a code which worked at my end
private void treeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e){
e.Node.BackColor = Color.Blue;
e.Node.ForeColor = Color.Red;
}
|

Navaneeth,
Eg.,
I have treeview like this
Root -> A1 -> A
B
C
In your case when I select A it gives Root as red in color. A should be colored as RED.(Node which is focussed). Please let me know if i am wrong.

Manowj

hello guys!!
i have a table with a collumn datetime type, in the winform i have datetimepicker so i choose a date and save but it doesn't work here is some code..
DateTime dtime;
dtime=dateTimePicker1.Value.Date;
row["Date"] = dtime;
the dtime variable contains the date, for example 12-2-2008 12:00pm
but when i click tha save button it sais it cannot convert datetime from string
|

|
|
Its always better to use string for saving Datetime.
Cheers!!

No. It's not a good practice.
|
|
|
|

You can say somewhat it's not a good practice but for better flexibility and avoid Exceptions one can use it.
It's all upto one what is one's way of coding
Cheers!!

It will make your code to be prone to error.

Try to parse that string to a DateTime instance and supply that to the table. There are methods like DateTime.TryParse or DateTime.Parse
|
|
|
|
|
even with that it is still the same
i write
DateTime.Parse(dateTimePicker1.Value.Date.ToShortDateString());
and it says again cannot convert datetime from string
i am very disappointed ((((((

FileIOPermission is there since .NET 1.1. Use the Demand method to check you have access to folders. Check the following code (not tested on .NET 1.1)
bool CanWriteToFolder(string folder)
{
FileIOPermission f = new FileIOPermission(FileIOPermissionAccess.Write, folder);
try {
f.Demand();
}
catch (SecurityException) {
return false;
}
return true;
} Check documentation[^] for detailed examples.
