sorry i don't know the solution either. But i really liked your comment and i would like to develop an uninstaller.exe too. It's quite a hazard to go to control panel every time i need to uninstall a sw. Specially it is disgusting for developers who need to test their project again and again.

Hope someone can give a solution.... i believe many people like me, will be happy to find a proper solution...

thanks

i fill a datatable with dataadapter and bind it to an bindingsource
one of my function return max(id) from above datatable:

<br />
datarow[] rows = ds.tables[0].select("id=max(id)");<br />

also datatble has updated whenever needed by:

<br />
datable dt=ds.tables[0].getchanges();<br />
adapter.update(dt);<br />
ds.acceptchanges();<br />

my function (select last id) work correctly for first update, but it dosn't work after add one new record, and return same record.
why? Confused | :confused:

Try to update the dataset instead of the datatable, and avoind performing dataset acceptchanges. If your Datatable is bound to the control, once you update the adapter, may be the call the binding again.

Ofcourse your best friend is debugging.

i don't have problem with update dataset or datatable, because both has update as well. but select function dosnt work probably Sigh | :sigh:

Hello,

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

accessred wrote:

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!

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!

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.
