Textboxes do not support autofill, you will need to find or write a custom control to do this.

I need some help creating an MS-Word counter macro as I'm not well versed in Visual Basic. I am trying to find a repeating XML tag pattern in an MS-Word file as shown below:
<subunit>
any text . . .
</subunit>
What I need the macro to do is to attach a number to the tag and each time the tag is found, the number should increment by 1.
See my desired output:
<subunit_1>
any text . . .
</subunit_1>
<p>
<subunit_2>
any text . . .
</subunit_2>
<p>
<subunit_3>
any text . . .
</subunit_3>
Can such a macro be created in Word? I do have some experience editing macros in the VB editor but very limited.
I might add that I already have a macro that duplicates an XML tag each time I run the macro but without the incrementing. Should I try to edit this current macro to get my desired output?
Thanks

Hi,
My application requires a date/time field to be set to display a blank field by default, unless modified by the user. Right now it displays the current date and, if not changed by the user, on saving the record that date is passed to the database. Could somebody please let me know how this is done?
Thanks in advance.

I have one last VB.NET newbie question for the masses and then I promise to make my way.
I have a list box with myriad entries and I would like to know when the user right-clicks a specific item in the list box so I can display a right-click menu with a couple options they can perform on that entry. How is this done in VB.NET?
Thank you!

You will need to add a context menu to the form.
<br />
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown<br />
If e.Button = MouseButtons.Right Then<br />
ContextMenu1.Show(Me.ListBox1, New System.Drawing.Point(e.X, e.Y))<br />
End If<br />
End Sub<br />

I wrote a scipt that takes an Access database and imports it to SQL Server. The Access db has over 1 million records in it. The script works, but around halfway through adding the records I get a "page cannot be displayed" error. It is strange because there is nothing in my script that tells it to change pages. This error occurs during the WHILE loop. If i look at my SQL db, i can see that the script is still running and adding records even though this error page appears. I think it may be some sort of server setting, but have not been able to figure it out. I need to redirect the user later in the script after this import completes, so I need to get this fixed. Here is my code:
<br />
Sub Cat1_Import()<br />
Dim startTime = Timer<br />
Dim AccessConn As OleDbConnection<br />
Dim AccessCmd As OleDbCommand<br />
Dim RecSet As OleDbDataReader<br />
Dim SqlString As String = "Data Source=mysource;Initial Catalog=mycatalog;Pooling=True;Min Pool Size=100;Max Pool Size=200;User ID=user;Password=pass"<br />
Dim SqlConn As SqlConnection<br />
Dim SqlCmd As SqlCommand<br />
Dim SqlRecSet As SqlDataReader<br />
Dim UpdateSql As String<br />
Dim SelectSql As String = "SELECT * FROM [Equipment Contract Pricing]"<br />
<br />
'connect to Access db<br />
AccessConn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;data source=path-to-my-db\Equipment.mdb")<br />
AccessConn.Open()<br />
AccessCmd = New OleDbCommand("SELECT * FROM [Equipment Contract Pricing]", AccessConn)<br />
RecSet = AccessCmd.ExecuteReader()<br />
<br />
'connect to sql server<br />
SqlConn = New SqlConnection(SqlString)<br />
SqlConn.Open()<br />
<br />
'loop through access db records to insert each record into Sql Server db<br />
While RecSet.Read()<br />
UpdateSql = "INSERT INTO [Equipment Contract Pricing] (CLIN, Offeror_ID, Product, ID_Number, Description, Specifications, Standards, ISO9000, Manufacturer, Model_No, Cat_Code, Sale_Area, Purch_Price, Price_Unit, YR, Last_Update_P) Values "<br />
UpdateSql &= "('" & RecSet("CLIN") & "', '" & RecSet("Offeror_ID") & "', '" & Replace(RecSet("Product"), "'", "''") & "', '" & RecSet("ID_Number") & "', '" & Replace(RecSet("Description"), "'", "''") & "', '" & Replace(RecSet("Specifications"), "'", "''") & "', '" & RecSet("Standards") & "', '" & RecSet("ISO9000") & "'"<br />
UpdateSql &= ", '" & RecSet("Manufacturer") & "', '" & RecSet("Model_No") & "', '" & RecSet("Cat_Code") & "', '" & RecSet("Sale_Area") & "', convert(money,'" & RecSet("Purch_Price") & "'), '" & RecSet("Price_Unit") & "', '" & RecSet("YR") & "', '" & RecSet("Last_Update_P") & "')"<br />
SqlCmd = New SqlCommand(UpdateSql, SqlConn)<br />
SqlCmd.ExecuteNonQuery()<br />
End While<br />
<br />
SqlCmd = New SqlCommand(SelectSql, SqlConn)<br />
SqlRecSet = SqlCmd.ExecuteReader()<br />
If SqlRecSet.HasRows Then<br />
Session("import") = "Data successfully transferred."<br />
Else<br />
Session("import") = "Temporary table is still empty. There was an error importing the data."<br />
End If<br />
<br />
RecSet.Close()<br />
SqlRecSet.Close()<br />
AccessConn.Close()<br />
SqlConn.Close()<br />
<br />
Dim endTime, processTime, hrTime, minTime, secTime As Double<br />
endTime = Timer<br />
processTime = endTime - startTime<br />
hrTime = processTime / 3600<br />
minTime = processTime / 60<br />
secTime = Decimal.Remainder(processTime, 60)<br />
If secTime < 0 Then secTime = 0<br />
Session("time") = "Total Process Time: " & FormatNumber(hrTime, 0) & " hours, " & FormatNumber(minTime, 0) & " minutes, " & FormatNumber(secTime, 0) & " seconds"<br />
<br />
End Sub<br />
Anyone have any iseas why this is happening?
Thanks,
Mike

I just wanted to add to this post. I put a timer on the page and this error occurs at the 1 hour mark every time. I am pretty sure this is a server issue. Maybe there is a setting in IIS I am overlooking. Any ideas?

Hello!
I posted a bit ago with a question about a syntax error in a seemingly-flawless SQL string but now I'm back with what is hopefully a simpler problem:
In my program, record (tuples) in a database are represented as items in a list box. The user can select any item they wish from the list box and have all the information about that entry readily displayed to the form - this part is working just fine.
What isn't working is record deletion. Although the deletion itself is working (in that it does, in fact, delete the selected record), it does not update the primary key (an ID # in this case) at all thus after deleting a few random records I am left with a rather unorderly database.
I have tried manually updating the ID via an SQL UPDATE statement as follows:
oleCommand.CommandText = "UPDATE tblEvents (ID) VALUES (" + nCount + ")"
Where:
oleCommand = my OleDbCommand object
tblEvents = my table within the database I'm using
ID = the primary key of this table
nCount = a counter variable dually-used to step through a loop while setting the ID for each record.
Please let me know if oyu have any ideas and thank you in advance!

Hi
Is the ID field an AutoNumber?
|
|
|
|
|
I have tried both Autonumber as well as a regular Number and neither work. Currently, it is set for Autonumber
|

|
Hi
Is the SQL statement within the loop?

Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeleteSelected.Click
Dim strSQL As String = ""
Dim nIndex As Integer = 0
Dim nCount As Integer = 0
If lstHistory.SelectedIndex < 0 Then
MsgBox("You must first select the record you wish to delete.", MsgBoxStyle.Critical, "Selection Required")
Else
nIndex = lstHistory.SelectedIndex
lstHistory.ClearSelected()
strSQL = "DELETE FROM tblEvents WHERE ID = " + nIndex.ToString()
Try
oleCommand = New OleDbCommand()
With oleCommand
.Connection = New OleDbConnection(strConn)
.Connection.Open()
.CommandText = strSQL
End With
oleDataAdapter = New OleDb.OleDbDataAdapter(oleCommand)
oleCommand.ExecuteNonQuery()
oleCommand.Connection.Close()
PopulateHistory()
Catch ex As Exception
MsgBox(ex.Message)
End Try
Try
oleCommand = New OleDbCommand()
oleCommand.Connection = New OleDbConnection(strConn)
oleCommand.Connection.Open()
For nCount = 0 To nRecords
oleCommand.CommandText = "UPDATE tblEvents (ID) VALUES (" + nCount + ")"
oleDataAdapter = New OleDbDataAdapter(oleCommand)
Next
oleCommand.Connection.Close()
Catch ex As Exception
MsgBox(ex.Message)
End Try
End If
End Sub
The UPDATE SQL string is, indeed, within a For loop. I update the ID VALUE of that string with the counter (nCount) of the For loop in attempt to manually update each tuple's ID.

Hi
I think the SQL statement that you have used for the Update command should read:
"Update tblEvents set Id = " & nCount
Another thing - this is going to try to set the ID of all records in the table, you should specify a "where " clause, that identifies a unique record to be updated.

I'm trying to populate a drop down list from an arraylist.
I have an array called idnums
thought I could do something like this:
Dim C As Integer
Dim I As Integer
C = idnums.Count
For I = 0 To C
dlIdNums.Items.Add(idnums.Item(I))
Next
thanks
|
|
|
|
|
Are you taking about a ComboBox or ASP.NET Control DropDownList
No need for the Loop Just bind the Datasource to the arraylist.
dlIdNums.DataSource = idnums
dlIdNums.DisplayMember = "name" or DataTextField(ASP)
dlIdNums.ValueMember = "value" or DataValueField(ASP)
Check Help if I am wrong it is in there.
