You can't, unless you do an indeterminate one. Of course, it also needs to run in another thread.

I would like to know how to write out excel 2003 excel worksheets to separate files. Basically I need to write out each excel 2003 file generated by a vb.net 2005 desktop application to separate workbooks. Each separate worksheet is going to be email and encrypted for each customer.
Thus I would appreciate any suggestions that you have how to accomplish this task.
Thanks!

I'm assuming you already have Excel interop code written that creates the worksheet.
All you do is create a new Workbook, add a new Worksheet to it, populate it, and save. Rinse and Repeat.
Google results for "vb.net create new workbook"[^].

Thank you for your immediate response. However my question is can I reuse the excel object embedded in the vb.net 2005 desktop application? I need to put the output from sql server 2005 on separate spreadsheets for different customers. To accomplish this tak, it looks like I need to close and reopen the excel object each time I need to write to a new excel worksheet. Thus is there a way that I could reuse the object?
Thanks!

Yes.

Not true. You just close the existing workbook after you save it and create a new workbook, then add a new worksheet to it.
jazzgirl wrote: is there a way that I could reuse the object?
The simplest route, though no the most proper, would be to just create a class-level variable to hold the Excel app object, then you can use it through out the form class.

Hi I programmed Xcell Object in VB6 , and Here is My Idea ,How it works , it may not be
much different from VB-Net Code :
To Read from a specific cell on the Sheet --> to a variable use following Formats :
-----------------------------------------------------------------------------------
NUM = Val(Form1.Spreadsheet1.Cells(9, 5))
BRN = Val(Form1.Spreadsheet1.Cells(10, 5))
And To Write a value from a Variable to a Spesific Cell on a sheet Use Format below :
----------------------------------------------------------------------------------------
MM = 4 :' Say or any other value.
Form1.Spreadsheet1.Cells(MM + 3, 1) = MM
-----------------------------------------------------------------------------------------
If You are in Sheet1 and you want to send Output to sheet3 , this is Simple, Just Change
the sheet # and provide the Cell adress exactly as an example see :
JK ... has some value send it to sheet3 :
Form1.Spreadsheet3.Cells(7, 5) = JK
I hope I helped .

As far as I can see, i needs to equal 1 for this to work ? Have you stepped through the code to see what is blowing up ? Have you googled the HRESULT ? Is that all the error message you get ?
I googled the HRESULT and this was the first hit:

I have not used vb is about 15 years, I was wondering what I needed to do to get my program to allow me to pick a directory and load 3 dbf files in to the program so I can modify them if some one can point me in the right direction that would be great

wow, Is that mean the last version you use was VB3.0? It was released around 1993. What made you come back?

You are trying to read dbase databse? here is what you need
Add Microsoft DAO reference to your project then the following code will do some magic tricks
Dim sql As String
sql = "Select * From table"
Dim db As Datbase
Set db = DBEngine.OpenDatabase("C:\Database", False, False, "dBASE III;")
Dim recset As RecordSet
Set recset= db.OpenRecordset(sql)
This is may not compile, you will need to tweak it. It has been that long since working with vb

hello every one
I want that all the items of checklistbox which are checked to be entered in multiline textbox...for that my code is:-
Dim i, t As Integer
t = Me.chklistbox.Items.Count
For i = 0 To t - 1
Me.txtpov.Text = (Me.chklistbox.CheckedItems(i) & "," & Me.chklistbox.CheckedItems(i + 1))
Next
but this only works for two items rest are not seen
so please tell what shall i write in code to display every item that is checked comes in multiline textbox....

Hi,
a property that gets several values assigned to it only remembers the last value, so having Me.txtpov.Text = something in a loop like that does not make sense. Either use a Control that knows how to collect multiple items, or concatenate all strings you want to be shown.

Dim i, t As Integer
t = Me.chklistbox.CheckedItems.Count
For i = 0 To t - 1
Me.txtpov.Text = Me.txtpov.Text & Me.chklistbox.CheckedItems(i) + ","
Next
* You were counting all the items in your loop, whilst you only want to iterate through the checked ones.
* You were overwriting your textbox with the text of the last two items found, whilst you want to append text to the textbox, for each checked item.

hi
the code u suggested works thank you very much...
but problem is that all the items are added to multiline textbox after i click save button..
for eg:-
if i tick on item 'a' of checklistbox and then click on save button that item appears in multiline textbox now suppose i again tick on item 'b' in checklistbox and than click save button at this item 'a' is again added to multiline text box so the outcome is 'a','a','b' which means repetation of 1st item this happens every time i click on save button...
my code is:-
Private Sub btnsave2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave2.Click
Try
If Me.chklistbox.SelectedIndex = -1 Then
MsgBox("nothing selected")
Exit Sub
End If
Dim i, t As Integer
t = Me.chklistbox.Items.Count
For i = 0 To t - 1
Me.txtpov.Text = Me.txtpov.Text & Me.chklistbox.CheckedItems(i) + ","
Next
Catch ex As Exception
ex.ToString()
End Try
End Sub
please suggest what shall i do to clear multiline textbox before saving it...
|
|
|
|

Try
If Me.chklistbox.SelectedIndex = -1 Then
MsgBox("nothing selected")
Exit Sub
End If
Dim i, t As Integer
Me.txtpov.Text.Clear()
t = Me.chklistbox.Items.Count
For i = 0 To t - 1
Me.txtpov.Text = Me.txtpov.Text & Me.chklistbox.CheckedItems(i) + ","
Next
Catch ex As Exception
ex.ToString()
End Try

Hi,
How can I use { in my string.Format?(it's part of my string) and & _ for contacting string. In below code it says 'Input string is not in correct Format':
<br />
String.Format("function (s,e){if(e.item.name == 'OtherField'){if(" & _<br />
"'{0}'.IsCustomizationWindowVisible() == false){" & _<br />
"'{0}'.ShowCustomizationWindow()} else{" & _<br />
"'{0}'.HideCustomizationWindow()}" & "}else if(e.item.name == 'Group'){" & _<br />
"if(e.item.GetChecked()){'{0}'.PerformCallback()}}}", Me.ClientInstanceName)<br />
Best wishes
