I used a progressbar in my form and want to show it's value on a lable by this code :

for(i=0;i<100;i++)
{
   for(j=0;j<100;j++)
   {
      // DO ...
   }
   progressbar.value = i;
   lable.Text = i.tostring()+"%";
}

but lable's text doesn't change in progress and just in the end of loop(i) shows the 100%.

any suggestion? thanks.

Try to run your procedure in other thread.
This article will help you to do it.

My english is not so good. Please, correct my errors.
Best regards, Alexey.

Hi,

just a short hint. Maybe it is not the best possibilty (running an own thread is much better), but try to use

Application.DoEvents()

after you reset the text of the label to its new value.

This is due to UI doesn't get time redraw its area

do this

<br />
lable.Text = i.tostring()+"%";<br />
this.Refresh();<br />

It is enough to refresh the label.

label.Text = i.ToString() + "%";
label.Refresh();

hi all,
i store date as text format in ms access. (for example: '18.07.2006' is stored in a text field in my database)

but when i want to do some search according to date i want to use records in that field as date ???

i convert data (user entered dates to compare with the dates in my database in order to do some search) entered in textboxes into datetime but dont know how to tell the my program to behave as if the dates (which hold in text fields) in my database also are 'date'.

hope that i am clear enough.
thanks in advance and bye.

???

object can be everything. but guid is only a number with a format
"{15B37BBE-CE65-4a4c-83BD-79906975D223}".

What kind of object do you want to convert ?

How about item = "" or item = null?

How about reading this forum? You'll find lots of questions that seem to trip people up.

Recursion and looping?

Can we replace recursion by looping for example using a for loop or a while loop?

You may don`t use loops at all roo. There are some languages (eg. Erlang), where u dont have any loops, just a recursion.

So its definitely possible, but weird, complex and nasty

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
