An animated gif file would be the easiest way probably.

Hello,

I don't think that there is an easier way than using a timer.
But maybe I'm wrong.

All the best,

Martin

The easiest way would be a Forms.Timer

You really should wait way longer than 40 minutes before posting again about the same issue and with very little more information!

Spamming the boards won't get an answer any quicker and will probably make some people ignore you.

Hello.

Have been trying to search for the real working behind the concept of boxing/unboxing.

I understand the concept and its utility, but dont know what exactly happens behind the scene as per memory address and the apropos changes in the stack and heap memory.

Any information or reference will be of help.

Thanks.

Hi,

Dont try to compare the strings without the help of DateTime.
Let the DateTime class parse your date strings, then compare the DateTime values.

Problem with SelectedIndexChanged method

Rajesh R Subramanian9-Jul-07 21:36

Hello all,

I have a form and a few comboboxes in it. When the user drops down a combobox and selects a different item, I wish to execute a piece of code, which involves a alot of database transactions. I am handling the SelectedIndexChanged(object sender, EventArgs e) event of the combobox. But this method gets called even if the user has selected the same item, which was previously selected. Am I handling the wrong event or is there anything more I need to do?

Ofcourse, you are handling the right event.
All you need is a simple if statement block like this

if(comb.SelectedIndex !== currentSelection)
{
/// All your code goes here
/// Where currentSelection is a user defined variable which must be
/// member of your Form class
}

Does this help

Hello there,

Thank you very much for your inputs. I don't get it. Isn't the handler supposed to check it? The name of the handler is SelectedIndexChanged and why in the hell should I check if it is changed or not? Why does this event handler even exist? Shouldn't this event be triggered only when the selected index of the particular combobox is changed? Oh crap! Is this the way C# works? I think I am going back to MFC.

Unfortunately, there are a lot of PropertyChanged events in C# that are fired whenever a value is set whether a the value really changed or not.

And it is very annoying!

But going back to MFC isn't really an option for me Smile | :)

I'm annoyed too! But, I think I must get used to it rather than bitching about it Smile | :)

What is that currentSelection here? Am I supposed to maintain a static variable where I store this information?

Then why do we have an OnSelectedIndexChanged event handler? Doesn't that suck?

Hello,

You are write!
Also the SelectedValueChanged has this behavior. It doesn't check for current setting! Frown | :(

Maybe the TextChanged helps you here. (I know that it could be multible text in the Items!)

All the best,

Martin

Thanks for pointing it out. I had two projects open, and got confused between both. But I think I may run into trouble, because the combobox item text might be changed dynamically depending on a table updation in the database. Somehow, this problem is fixed for now. Thanks a bunch again.
