getnanda@gmail.com wrote: updation of the values with millisecond accuracy is required
Are you planning to update the monitors too because a typical monitor will refresh the screen only one and three quarter times in the current time it takes to update all the text boxes.
If you update textboxes every millisecond the monitor will only have got 6% the way through a refresh before the thing is updated.
I really think some pragmatism is required here.

Hi,
three comments:
1.
the system clock has a resolution of only 10 to 20 msec depending on hardware;
so I am not sure I trust your time measurement. See my timers article.
2.
400 textboxes is just silly. If all they do is show a little string, I suggest
you take them all out, and paint those strings directly to one big Panel, or
to the Form itself. That way you are in charge and not wasting any resources.
You can still have your own myTextBox class that has Location, Text and whatever
properties you like (less is more); plus a collection of those; then a Paint handler
that enumerates the collection and paints these "lightweight labels".
3.
I agree with who ever said updating a screen every msec does not make much sense,
so you might run your simulation at "full speed" and update the display say
every clock tick or every other clock tick.
You can do this by not calling Invalidate() when you change the drawing,
but instead have a periodic timer call Invalidate(). This works well together
with the lightweight labels.

I don't know who voted you a "1", but this suggestion would get far better performance than updating 400 textbox's (BTW, ridiculous!) individually.

Why thank you kind sir - but there was no need. I just thought your well balanced and well argued post needed to be 5ed.

Hi,
Use Temperory Table. Save all textbox values into that table. And finally use TableMapping for updating the Original database table.

Are you suggesting to use a database in order to speed things up 
That's a novel approach...

If it's raised via a COMException, you just catch that. There is a gotcha however. See link[^].

hi, i have a c# windows application, from which the details can be exported to a Excel file. after exporting the application ask "Do you want to see the file". suppose the user clicks "yes", i want to show the file....
How can i open the file from the application?
My small attempt...
|
|
|
|
|
You can use OleDb driver to retrieve the data and display it using datagridview
|
|
|
|
|
What is this? please go through the question before you answer..... ok?
My small attempt...

I explained how you can show data from excel file in your application. If you want to open ms excel then use Process class and specify the path of file you want to open.
|
|
|
|
|
i just want to open the Excel file.... as (double cick).............. just to see the file
My small attempt...
|
|
|
|
|
Have a look at Process class
|
|
|
|
|
|
you can also take a look here.
Your problem is perhaps not so simple as you assume....

will solve the probelm

HELLO Friends,
My objective is to make a neive compiler as my semester project!
i have decided to make compiler which is capable of converting C-language to
C# (it will convert some basic codes not the complete language).
According to the requirments i have to present a documentation of my project in such a way that it includes complete lexical analysis(class and value part table) of my compiler.
I just need an idea which can lead me to the begining of the documentation.
If anybody can tell me as soon as possible i will be very thankful!
THANKING YOU!
Regards,
SANA.

Gosh. It's urgent. That's highly original of you. We'd never have realised it was any more urgent than the thousands of other "urgent" messages without you telling us.
There's this wonderful tool called Google that may have slipped your attention. It might just help solver your problem. Clickety[^]
