Hello,

First I have to say that your problem has nothing todo with your subject line. (you have no problem with the tabcontrol)

What does it do?
Have you debuged it?

accessred wrote:

Where have you placed that code?

accessred wrote:
Convert.ToInt32(Txtapti.Text);

This is not good, as it will throw an exception if you input a non int string in your textbox.
I would do a int.TryParse if you have .Net > 1.1 or double.TryParse if you have .Net < 2.0.

All the best,

Martin

Nothing you have to be ashamed for, everybody started once and had also "small" problems.

Don't understand that!

I understood the question also at the first time.
But I asked 3 questions and you answered 0 of them.
So with no more information about your code, we will not be able to help you!

All the best,

Martin

answers:
1) i debugged the code.when running no error is coming,jus not displaying the result.

2)code placed in
private void Txtresult_TextChanged(object sender, EventArgs e)

3)double.TryParse is not working.error comins as:
"no over load for method tryparse takes 1 arguments"

"I am burning...the only thing rest in me is you..."

Problem with sending email embedded with multi media content (images,graphs etc.,)

So, I would assume that the code is not executed because you are not changing the code of the result textbox.
You actually whant to write the result to the textbox.
I would think, you should place a button on the page and on Click you execute the code.

accessred wrote:

As you said you have .Net 2.0 you could also use the int.TryParse, but here is the way I would do it in .Net 1.1

using System.Globalization;
double d;
int i
if(double.TryParse(label.Text,NumberStyles.Integer, CultureInfo.CurrentCulture, out d))
{
    i= Convert.ToInt32(d);
}

Hope it helps!

All the best,

Martin

Can any one help me in this aspect ?

Many thanks,

I tried something like that.
First I tried with CellBeginEdit and CellEndEdit but the ComboBox control didn't appear (just it's editable box). Then I used CellClick and CellValidating. It worked, but I had to solve the "reentrant call" problem - finally I find the solution on the net.
I explained it here: Dynamically change DataGridViewTextBoxCell to DataGridViewComboBoxCell

You didn't specify the source of "your" date time format but it really shouldn't matter.

If nothing else you can compare the individual fields.
DateTime tmp = DateTime.Now();

if ( your.year == tmp.year &&
your.month == tmp.month ...

You get the idea.

If you use visual studio put the cursor on DataTime and press F1. Smile | :)

If you know the input format, you can parse it manually to get the date, month and year. With this, you can construct a DateTime object and convert it to whatever format you please using the ToString() method and its overloads. Alternatively, you could just build the date string you need using the date, month and year that you've extracted.

A word of advice - if you're exchanging data between different apps, the ISO format (yyyy-MM-dd) is the only sane thing to use.

I tried to reply to your email but had a display name problem and could not.

If you are still having problems send an email to this message giving me a sample of
the code you are having the problem with.

I will be able to look at it and respond to you then.

Try: DateTime.ParseExact()That takes the date/time as string and the format as string array.
