Hi, I have example here on how to get the difference of date and time in C#.
Please follow these step:
Step: 1
Create a timer then set the interval to 10 and enabled to true.
Step: 2
Create 3 Label. Label1,Label2,Label3.
Step: 3
Create 2 Datepicker. Name it dtfrom and dtto.
Step: 4
Create a Button1
Then Copy this Code at your form:
private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
{label1.Text = dtfrom.Value.ToString();}
private void timer1_Tick(object sender, EventArgs e)
{label2.Text = string.Format("{0:G}", DateTime.Now);}
private void button1_Click(object sender, EventArgs e)
{
TimeSpan ts = new TimeSpan();
DateTime dt1,dt2 = new DateTime();
dt1 = dtfrom.Value;
dt2 = Convert.ToDateTime(label2.Text);
ts=dt1.Subtract(dt2);
label3.Text = ts.ToString(); //Answer
}

Try This:
Public Class Form1
Dim NowWas As Date = Now
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox1.Text = Now.Subtract(NowWas).TotalMinutes.ToString
End Sub
End Class
|
|
|
|
|
Try TextBox1.Text = Convert.ToString(NowIs-NowWas)
|
|
|
|

how can i go from the last item in a combobox to the first item.
With the folowing code i go always to the second item.
Private Sub ComboBox1_MouseWheel(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ComboBox1.MouseWheel
Dim x As Integer
x = ComboBox1.SelectedIndex.ToString
If x = 95 AndAlso e.delta = -120 Then
ComboBox1.Text = ComboBox1.Items(0).ToString()
End If
End Sub
so i tried a lot of things but i gives me always the second item.
thanks.

If you want the first item in the combo box to be selected, can't you just use:
ComboBox1.SelectedIndex = 0
?
|
|
|
|
|
no even that gives the second item
|
|
|
|
|
Are you sure that:
A) this code block is being executed
B) there isn't any other code which sets the selected index of the combo box after this code block.
I'm guessing that the index is being set elsewhere because ComboBox1.SelectedIndex = 0 will select the first item.
|
|
|
|
|
Yes i am sure
i wrote
if combobox.selectedindex = 19 then
combobox.selectedindex = 0
end if
and this gives me the second item
i had tried that before thats why i asked it here.
i would say try it.

Ah, I have just tested and found that after the selected index of the combo box is set, the mouse wheel movement is actioned. That is, if you scroll downwards, then after setting the combobox to index 0, the scroll down is done (but if you scroll upwards then it is fine).
The only way I can think of around this (which isn't very pretty) is to add and event handler after setting the index of the combo box. Something like:
Private Sub ComboBox1_MouseWheel(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ComboBox1.MouseWheel
If ComboBox1.selectedindex = 19 then
AddHandler ComboBox1.SelectedIndexChanged, AddressOf SetIndex
End If
End Sub
Private Sub SetIndex(ByVal sender As Object, ByVal e As System.EventArgs)
ComboBox1.SelectedIndex = 0
RemoveHandler ComboBox1.SelectedIndexChanged, AddressOf test
End Sub
Like I said, not a pretty solution so maybe someone else has other ideas?

your solution doesn't work because of the word "test".
Test is not decleared.
if i change it to setindex in run the project then the first item does not come it stays at the last item.
sorry couldn't response earlier
thanks
|
|
|
|
|
the only ting i can do is ad an emtpty string as last item
and then
If ComboBox1.SelectedIndex = 20 Then
ComboBox1.SelectedIndex = 0
20 is the last item as a empty string
that works but it's like you said even not so nice.
|
|
|
|

I figured out a solution:
dim i as integer
Private Sub ComboBox1_MouseWheel(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ComboBox1.MouseWheel
Try
If ComboBox1.SelectedIndex = ComboBox1.Items.Count - 1 And e.Delta = -120 Then
i = ComboBox1.SelectedIndex
ComboBox1.SelectedIndex = 0
Else
Me.OnMouseWheel(e)
End If
Catch ex As Exception
ComboBox1.SelectedIndex = 0
End Try
End Sub
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
If i = ComboBox1.Items.Count - 1 And ComboBox1.SelectedIndex = 1 Then
ComboBox1.SelectedIndex = 0
i = 0
End If
End Sub
It's funny though, how that mouse wheel event only lets you perform actions in between turns (so to speak).
My advice is free, and you may get what you paid for.

 thanks eddy that's it
thank you

You're welcome.
Now you just need to figure how to adapt this to also work when you scroll up 
Cheers,
Johan

Hi,
How is this happening then?
Setting the Text property of the combobox implicity changes the SelectedIndex property. Therefore your code must set SelectedIndex to 0.
ComboBox1.Text = ComboBox1.Items(0).ToString()
But what happens next? The default mouse wheel handling then increments the SelectedIndex from 0 to 1 to give the observed effect of always getting the second item selected.
The solution must be to disable the default handling for the one special case of wrapping the index from bottom to top and you’ll have to do this via an override of the OnMouseWheel method.
In c# I'd do this
protected override void OnMouseWheel(MouseEventArgs e) {
if (specialcase) {
SelectedIndex = 0;
} else {
base.OnMouseWheel(e);
}
}
Let me know if this works, as it's a bit of a guess on my part.
Alan.

i can't make it working because
specialcase is not declare

Oh come on, try using your brain this morning! Specialcase is just a placeholder for the boolean condition that you already have,
VB x = 95 AndAlso e.delta = -120
c# x == 95 && e.delta == -120
Also you will need to subclass the combobox class to override the method.
Alan.

There is no way to modify this to work with Word. It's (very) specifically written to work only on Excel workbooks and, according to the comments, doesn't even reveal the plaintext password, but the hashed version of it.
Noone is going to help you write a tool to crack passwords. Period.

OK, i see several softwares to retrieve word .dot file password. One i used it is this ...
http://www.petri.co.il/word-password-recovery.htm[^]
But none of them worked because, the software is trying to retrieve default project in the dot file. Not the second project which i need to retrieve the password.
Do you have any suggestions to come up on this?

Chances that anyone is going to help you are slim, since you're trying to open things that the original owner doesn't want you to open.
As comparison, you wouldn't want me to explain how everyone can retrieve the password to your computer, now would you? No amount of locks on the door will keep you 100% safe, but that doesn't mean that we should encourage burglary
There are enough programs available for free that do this stuff. Use them at your own risk.

Agree,
But this my user forgot his password and he own want to get it rectified it.
Without opening the .dot file i cannot solve his problem.But he forgot the password to open the file though.
The problem is, He has upgraded the ms office version and template (Somename.dot) was supporting was not supporting now. When i start saving the file i am getting error.
How i can get rid of this? any ideas ? so that i can atleast save that file.

So you can 'open' and 'read' it? Copy and paste to a new file, and save that?
