Microsoft has an interop library for controlling Excel, that's what you probably want to look at.

Hii
First import the microsoft.office.interop.excel library and then use the following code to insert data in excel sheet.
dim xlapplication as new excel.application
dim myworkbook as new excel.workbook
dim myworksheet as new excel.worksheet
myworksheet.cells(1,1).value="Name :"
myworksheet.cells(2,1).value="Address :"
myworksheet.cells(3,1).value="Age :"
Thanx

Is there anyway to translate this Excel program into a VB.Net one ?
The Program goes like this:
I enter 2 fields : Density & Temperture .
They will be converted and used later on to get the Coefficient , The putput is Tabel ASTM table 54-B
2 Input Boxes: in locations
I8 and J8
Box K8
=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
Box L8
=IF(K8<=771,(346.4228/K8^2)+(0.4388/K8),(IF(K8>=771.1,(IF(K8<=787,(2680.3206/K8^2)-0.00336312,(IF(K8>=787.1,(IF(K8<=838.49,(594.5418/K8^2),(IF(K8>=838.5,(IF(K8<=1075.5,(186.9696/K8^2)+(0.4862/K8))))))))))))))
Output Box M8
=(ROUND(EXP(-L8*(I8-15)-0.8*(L8^2)*((I8-15)^2)),4))

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.

Hy,
I just wanted VB.Net program or formula that do the same job as the Excel one. That's all. I couldn't read well the Excel formula & I need to use i in VB.Net.

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.

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.
