You can as long as the type you are using can be evaluated to a numerical value.

I'm not so sure but I think u must be using COM here and the component your app is trying to use is not there in the registry.

thanks.
how can i registry COM in my application ?
|
|

well personally I hadnt had enuff exposure of COM but I've seen such issues comming at a few places,
generally I've seen ppl registering the required DLLs but for that you gotta know which dlls your application is using. RegSvr32 is a command you should search out for, its used in command prompt by the way. I hope its a bit helpful to u:->

Hi,
I currently do the following when closing a form containing editable databound controls (comboboxes mainly)..
this.configBindingSource.EndEdit();
if ((bool)this.myDataSet1.HasChanges())
// do some stuff
The problem is that if I bind a control's tag to a field in the datatable, the above condition is met even if there are no changes made to the form's controls at all. Even if I bind it to a label.tag, it still triggers a change to the datatable.
Is there something I'm doing wrong?
Thanks.

No you're not doing something wrong, but you have to know something about data binding:
Whenever you bind something to a property (Tag in your case) that does not have a corresponding PropertyChanged event (TagChanged event in your case) then the data binding framework assumes that the value has changed. Therefore the value is written back to the data source even if the value hasn't changed.
If this is the reason for your problem then you can:
- define that the binding is only unidirectional (from data-source to control and not back). This can be defined somewhere, but I can't remember where (we don't use data binding anymore)
- derive a class from that control and implement the TagChanged event
- use something better than data binding (MVP)

Thanks for that - in this case I'll handle the situation differently.

HH:MM:SS
when any users opens my application i want to display this timer on the main form,,
in the start its three digits are set to 00, than seconds starts increasing and than minutes, and than if necessery hours also ,, how to do that ?

Surely a count down timer counts down, not up?

I'm not going to give you the code - but I will give you some hints. How often do you think your timer will update (take a look at this[^] article before you commit yourself)? How do you think you need to divide the values up (think about dividing by 60 - and multiples thereof)? You are going to need a formatter.
Alternatively, you could use a trick and get the difference between the time your application starts counting and the current time using the DateTime classes. Again you will need a timer.

Good luck in your endevour. However, I assume you actually wanted to ask a question rather than tell us all what your plans are.

Good luck with the coffee. Remember, be careful of the hot water... It can burn you if you are not careful.

You see, that's the type of advanced stuff that only comes about through knowing how to do things like TDD and refactoring.
