You have an excel formula and you want to write a VB program that does the same ? Seems pretty simple to me, do you know any VB ? If you don't and you have no intention to learn, it could save you some grief to just pay someone to write this for you.

Hii
Use like this
myworksheet.cells(11,8).Formula= "IF((J8*100)-INT(J8*100)<0.1,INT(J8*100), _
IF((J8*100)-INT(J8*100)<0.3,INT(J8*100)+0.2,IF((J8*100)-INT(J8*100)<0.5,INT(J8*100)+0.4, _
IF((J8*100)-INT(J8*100)<0.7,INT(J8*100)+0.6,IF((J8*100)-INT(J8*100)<0.9,INT(J8*100)+0.8,(INT(J8*100)+1))))))*10"
may be this helps you.
Thanx

I have a dropdown list box on in a web application.
When a user clicks on an item, I want it to
be removed from the list. Below is my code for doing that:
Protected Sub ddlSelected_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlSelected.SelectedIndexChanged
If ddlSelected.SelectedIndex <> -1 Then
ddlSelected.Items.RemoveAt(ddlSelected.SelectedIndex)
End If
End Sub
My problem is, when a user clicks on the last item in the list, it does
not get removed. How do i handle this?
|

HI,
Here is an alternative,
would you consider trying to clear the drop downlist seeing that it is the last item in the list.
me.dl.items.clear()
just a thought,
Thanks

Hi ,
i am using vs2005 and tried using the below command...it works for me...
If Me.dlCustomers.Items.Count = 1 Then Me.dlCustomers.Items.Clear()
not sure why it wont work for you....
sorry! 
|
|
|
|

Here's the new code i'm using:
If ddlSelected.SelectedIndex <> -1 Then
ddlSelected.Items.RemoveAt(ddlSelected.SelectedIndex)
ElseIf Me.ddlSelected.Items.Count = 1 Then
Me.ddlSelected.Items.Clear()
End If
Still won't work because if there's only ONE item in the list, there's no
textchange event to fire nor indexchange event to fire.
Anyway, I changed the dropdownlist box to a regular listbox and my code works fine.
I appreciate the help.

The way you have this written, the If Me.ddlSelected.Items.Count=1 statement will never be executed. If the user has selected the last item on a list, then If ddlSelectedIndex <> -1 is TRUE, and so the ElseIf statement is never reached.
Try:
If ddlSelected.SelectedIndex <> -1 Then
If ddlSelected.Items.Count = 1 Then
Me.ddlSelected.Items.Clear()
Else
ddlSelected.Items.RemoveAt(ddlSelected.SelectedIndex)
End If

No, there is no such method in the framework.
If there were such a method it would not be in the Math class, it would be somewhere in the System.Drawing namespace where the Point structure is.
Despite everything, the person most likely to be fooling you next is yourself.

ROTFL. It's amazing what people expect VB to be able to do, nowadays....

Do NOT post similar questions more than once right next to each other in the same forum. Along with that you should also use the code blocks to make your messages more readable.

hi i've created a form which edit & diaplayes data into a data grid..
when i save data through Save button click data gets saved but if i (after entering 3-4 records) press shortcut key as <Alt + S> last record from the data grid not get saved .. even this is not displayed in the datasource during debug ...
i added a code because datagrid doesnt displayed next column without hitting the keys on last column...
If dgdcoccmast(dgdcoccmast.CurrentCell.RowNumber, 0).ToString <> "" Then
Dim cm1 As CurrencyManager = Me.BindingContext(Me.dgdcoccmast.DataSource)
cm1.EndCurrentEdit()
End If
but the problem remains....
Please help

What code did you write to make this shortcut key work ? How has the debugger led you to believe that it should be saving ?

Sir,
its not the shortcut key code since this shortcut is just to focus the Save button '&Save' event is firing is the btnSave_click only.. but in the datatable which i m using & binding to datagrid is not considering the last record because user is not hitting any key to generate the new row in the datagid instead it just saving the data....
|
|
|
|
|
OK, so you need to write code that detects that a record has not been saved, based on key presses in the grid ?

No i just need to write a code which saves all the records edited or added new in the grid on the pressing of Alt + s keys
