The reason why it doesn't work now is because you're using multiple binding sources. Knock that back to one binding source and update all the bindings and it'll work without any code.

If e.button = vb.VB6.MouseButtonConstants.RightButton Then
ContextMenu1.MenuItems.Clear()

Hi every one..
i have 2 buttons and one label..
if i click accept button time starts from 0 and if i click hangup button the label must dispaly how much time it hasd taken between two clicks....
can any body guide me how to achieve it....
|
|
|
|
|
put a timer on the form
put timer interval at 1 sec
on click of accept button start timer
on every timertick you increase a global variable by 1
on click of hangup button stop timer
do some calculating with the global variable and you know how much time past
(I'm sure there are better ways to do this but don't have the time to look for one at the moment)
If my help was helpfull let me know, if not let me know why.

A more accurate way than was suggested:
DateTime start;
button1Click
{
start = DateTime.Now;
}
button2Click
{
TimeSpan elapsed = DateTime.Now - start;
}
This approach is more accurate and simpler than playing with timers.

at timespan elapsed is giving me error
(i am using VB.Net for coding)
|
|
|
|
|
dim elapsed as timespan = date.now - start
should do it

how to show the progress as well...
|

|

that would need a timer that ticks periodically (say every 100 msec) and updates the label
to show the difference between now and start.

yup i have done that....
wat i need now is i want to display the time like continuously..... and after clicking hangup button it should show the total time it has taken to click the event.
|
|
|
|

so do it.
and if you need something new, read the relevant documentation and do some experiments.
And only if that does not help, ask a specific question on CodeProject...

That's because the code Christian posted is C#, not VB.NET. Though, it's easily translatable.

I am relatively new with programming and am having some issues with the following code. It is basically a calculator where I have 3 line of numbers in textboxes LINE1, LINE2 and LINE3. When I hit the + key on my keyboard it will add the first two numbers and displays the answer in the textbox LINE1. However it also shows “+” at the end of the result ie ”45+”. How do I show the result "45" without showing the key that has been pressed. Also happens when I use the other keys
as well. ( / * - )
Any help is appreciated
Thanks
Martin
Public Class HELP
Dim I As Integer = 1
Dim ANS, X, Y, Z As Double
Private Sub LINE1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles LINE1.KeyDown
If e.KeyCode = Keys.Add Then ' 3 values entered. 1 for each line and the plus key is pressed
If I = 1 Then
Z = CDbl(LINE3.Text)
End If
I = 2
X = CDbl(LINE1.Text)
Y = CDbl(LINE2.Text)
ANS = X + Y ' Addition of Line1 and Line2 as would a calculator
LINE1.Text = ANS
LINE1.SelectionStart = LINE1.Text.Length
LINE1.Select() ' Why is ther a plus sign at the end of the answer
LINE2.Text = LINE3.Text
LINE3.Text = ""
End If
End Sub
End Class

after you do your calculation put this on the next line:
e.handled = true 'this will handle the key, stopping its data being passed to the underlying control
so:
If e.KeyCode = Keys.Add Then ' 3 values entered. 1 for each line and the plus key is pressed<br />
If I = 1 Then<br />
Z = CDbl(LINE3.Text)<br />
End If<br />
I = 2<br />
X = CDbl(LINE1.Text)<br />
Y = CDbl(LINE2.Text)<br />
ANS = X + Y ' Addition of Line1 and Line2 as would a calculator<br />
LINE1.Text = ANS<br />
LINE1.SelectionStart = LINE1.Text.Length<br />
LINE1.Select() ' Why is ther a plus sign at the end of the answer<br />
LINE2.Text = LINE3.Text<br />
LINE3.Text = ""<br />
e.handled = true<br />
End If

Hi,
have a look at the KeyDown documentation...
from MSDN: Handled is implemented differently by different controls within Windows Forms.
For controls like TextBox which subclass native Win32 controls, it is interpreted to mean
that the key message should not be passed to the underlying native control. If you set
Handled to true on a TextBox, that control will not pass the key press events to the
underlying Win32 text box control, but it will still display the characters that the user typed.
If you want to prevent the current control from receiving a key press, use the SuppressKeyPress property

Hi Friends
Am in a bit of a pickle, and I now don't know how to fix this. I am trying to update the data in my dataset, and I am getting a concurrency violation. The application I am developing is to be used by, only one user, and there is no way that some one else could be using the dataset.
What could be the cause of this?
Thanks , I hope u will be able to help me.

Concurrency isn't just a multiuser issue. There are more than a couple of ways your own code can think it's updating records that it's not. The most common of which happens when your code goes to update a single record (such as when using the DataAdapter or TableAdapter), the number of affected records comes back 0 or greater than 1, because your table's primary key isn't setup properly, or if it doesn't even have one.

Hi, I got a problem when I try to get the value of numeric up down control. I have developed an application in vb2005 and contain a build in control numeric up down control. On the form i set the value of this control to 5 and in the code if i use the below code:
msgbox(numericupdown1.value)
the result in message box is 5. It is correct. But when I try the below code:
dim i as integer<br />
for i = 1 to numericupdown1.value<br />
listbox1.item.add(i)<br />
next
There is no value add into the listbox. I won't what is the problem? when I try to run the code in debugging mode, I found that numericupdown1.value=5D not equal to 5. So when the code reach the for next statement, it ignore and nothing happend. Does anyone know how could i solve this problem? Thank in advance.
