Thanks Christian!
But it now gives an error "Invalid escape sequence" I've looked around, and perhaps, could it be something about the "\" and "()" characterization?

There are no controls that do this, you need to buy custom controls, or write your own.

Hi all. I have seen many applications that listview ONLY updates when new data is avilable or when current data changes. I am making an application that deals with similar case. But i don't know how these applications achive this task. I tried to use timer to refresh my listview every few seconds(I am loading data from dynamic xml to listview.)But there is a big problem that i keep losing focus on the form and i see many unnecessary refreshes!! Could any one show me a better solution to avoid these unnecessary refreshes?I know these professional applications are using a method that i am not aware of.Thanks

The solution is surprisingly simple and you use them every day. They're called "events". If you break your application into seperate layers for UI, business logic, and data, the opportunity to create your own events that signal changes in the data becomes clear. Then all you have to do is subscribe to those events in your UI code and you've got your solution.

Dave thank you for reply.I am not very experienced vb6 developer.So i need some more information about this process.
In my case i have a listview that it gets data from a dynamic xml file. I use timer to re populate the listview every few seconds. Obviously this cause lots of flicking and lose of form focus and i see lots of unnecessary listview reloads. Could you consider this case and let me know how to reload listview ONLY when new data has arrived. I have seen it many applications doing that but don't know how they do it!! Looking forward for some examples.Thanks

Since you're reading from an XML file every few seconds, there isn't a simple solution to this. You'd have to implement your own method of detecting changes in the file, like checking the Modified date/time on the file, in order to fire the event.

Hi Everyone!
I need to keep track of what line the Cursor is on and the position of the cursor on each line in a Rich Text Box. I am trying to get the Speech API to read out the Line/word where the cursor is situated. I am using VB .NET.
Is there any way of determining these values?
Best Regards.
Josh

Hello,
I am trying to search for specific text in a file but I would like to use a wildcard and I don't know how to implement it, here is what I have so far:
<br />
If strfilecontent.IndexOf("this is the first part") <> -1 Then<br />
messagebox.show("found")<br />
end if<br />
I would like to know how to use a wildcard so that the following strings be detcted:
"this the first part"
"this is the first part"
"this was the first part"
and I know that I could use multiple If statement however this is just a sample of what I would like, so thats why I would like to use a wildcard so that I wouldn't have to create multiple if statements.
Thanks

You can use regular expressions to search your text, but I don't believe there are any classes that offer wildcard support (regex is better anyhow )
www.expresso.com[^] ( I believe ) is the place to download Expresso, an awesome tool for learning regex. There is a version on CP as well, I believe....

I'm getting a syntax error when debugging the code on the following line.
disc1ID = CType(mycmd.ExecuteScalar(), Integer) in the below code. All the error give me to go on is syntax error. ???
Any idea what the problem could be?
Private Sub NewToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripButton.Click<br />
<br />
Dim mycmd As New SqlCommand("SELECT MAX(DiscountId) AS discID FROM(Discountstructure)", MDIParent1.Conn)<br />
mycmd.CommandType = CommandType.Text<br />
<br />
Dim disc1ID As Integer<br />
<br />
MDIParent1.Conn.Open()<br />
disc1ID = CType(mycmd.ExecuteScalar(), Integer)<br />
MDIParent1.Conn.Close()<br />
<br />
MsgBox(disc1ID.ToString)<br />
End Sub

Remove the parentheses around the table name.

Hello,
I am creating a user control in the CF 2.0 for a PDA smart device.
When the user creates an instance of the user control it will assign variables to the controls on the user control in its constructor.
However, this works fine for all the controls, apart from the cboUsers, and cboType. The name, and type contain actual string data, and I have checked this with the debugger. When I place the cursor over the combo boxes after the line has been executed, nothing has been assigned and the combo boxes end up with just an empty string.
Does anyone know of a solution to this problem,
many thanks in advance,
Steve
Public Sub New(ByVal name As String, ByVal type As String, ByVal scheduledTime As Date, ByVal< scheduledDate As Date, ByVal details As String, ByVal status As String, ByVal completionNotes As String)<br />

<br />
Me.cboUsers.Text = name 'Does not assign the new name<br />
Me.cboType.Text = type 'Does not asign the new type<br />
Me.dtScheduledTime.Value = scheduledTime<br />
Me.dtScheduledDate.Value = scheduledDate<br />
Me.txtDetails.Text = details<br />
Me.cboStatus.Text = status<br />
Me.txtCompletionNotes.Text = completionNotes<br />

Hello,
Working in visual studio 2005, I have managed to create, setup, and populate a datagridview as follows:
Dim ds As DataSet = New DataSet
'FILL DATASET
da.Fill(ds, "qryTableReports")
ds.Locale = System.Globalization.CultureInfo.CurrentUICulture
'DISPLAY DATASET TO DATAGRIDVIEW1
DataGridView1.DataSource = ds
DataGridView1.DataMember = "qryTableReports
'SET COLUMN WIDTH
DataGridView1.Columns(0).Width = 25
DataGridView1.Columns(1).Width = 125
DataGridView1.Columns(2).Width = 50
DataGridView1.Columns(3).Width = 50
DataGridView1.Columns(4).Width = 50
DataGridView1.Columns(5).Width = 45
'*** END DATAGRIDVIEW1 SETUP
What I want to do now is to be able to select any row from my data grid, and once selected, it will open up a new form with the dataset from the row selected.
How can I accomplish this? Is the DataGridView control the best control to use in this case?
Thanks in advance.

Is this a case where you want to have like a list of orders and want to open the specific order on a seperate form when you doubleclick the row on the datagridview or something like that?
|
|
|
|
|
Yes. That is exactly correct.
|
|
|
|
|
OK....I have just been doing the exact same thing and have it working great. Here is what you need to do:
1) Declare a public parameter as integer on the MDIParent form called something like OrderID or whatever
2) on the doubleclick event on the datagridview you need to:
-Get the correct orderID from the datagridview by specifying the correct index (column) value on the currentrow.
-Set the orderID parameter = ID found on the datagridview
3) on your table adapter that is called on the load event on the new form you need to pick up the MDIParent.OrderID in a parameterized fill query.
Let me know if you need some example syntax?
Let me know and I'll post some.
|
|
|
|
|
That's great... Could you please post some sample code? I have declared my variable, but it is not passing the id to the other form when I double click on the datagridview row...
Thanks for your assistance!

Just to clarify....by MDIParent I mean the MDI frame form. I have found that is a stable base to place parameters that need to be shared between forms.
here is a syntax example
Private Sub CustSalesOpportunityDataGridView_CellDoubleClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles CustSalesOpportunityDataGridView.CellDoubleClick<br />
<br />
<br />
MDIParent1.SalesOppToOpen = Me.CustSalesOpportunityDataGridView.Item(0, CustSalesOpportunityDataGridView.CurrentRow.Index).Value<br />
<br />
Dim SalesOpportunity As New NewSalesOpportunity()<br />
SalesOpportunity.Show()<br />
End Sub
This should work for you too
