View 4 RepliesI have a listview and a textbox under it. Whenever a user input's text, I want the listview to filter. The code I have works, but the listview doesn't load the filtered data. I think it's because the listview has 2 columns of data that it's loading. [Code]

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.
I want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
protected void TextBox1_TextChanged(object sender, EventArgs e) {
dvProducts = (DataView)Session["ListViewItems"];
string serachText = EscapeLikeValue(TextBox1.Text);
string lvValues = hdRetailCustomerGroup.Value;
string trim = lvValues.Replace(" ", "");

I'm having a little trouble trying figure out a way to filter specific file formats to only show in a Listview. For example I only want .txt files to show in a Listview and no other file formats. Is this achievable?I've had a look around the net but not found anything relevant to what I am trying to achieve.
View 2 RepliesI have a WPF ListView that I am trying to filter within a BackgroundWorker. My code is shown below:
Dim Worker As New BackgroundWorker
AddHandler Worker.DoWork, AddressOf Me.FilterAsync
Me.TextBoxText = Me.TextBox.Text
Worker.RunWorkerAsync(Me.TextBox)
[code]....
This code runs through the filtering however it fails with an error "The calling thread cannot access this object because a different thread owns it." on the following line:
ListView.Filter = New Predicate(Of Object)(AddressOf Me.FindItemsAsync)
What would be the problem here? I can't seem to find any samples with filtering through the BackgroundWorker.

Hey guys I am developing a project in which I need to create kind of like a virtual mouse within the form that can move around the form and click buttons and such without taking control of the person's mouse.
is this possible to do
I need to communicate with a BlackBerry cell phone, so that I can query the current signal strength using Hayes AT commands, and store is into a file, along with my current GPS position.
I already got it to work perfectly using HyperTerminal:
- I installed BlackBerry Desktop Manager and I leave it running on the PC (otherwise it does not work!)
- I connect my BlackBerry Bold cell phone to the PC using a USB cable.
-The cell phone appears on the PC as a Virtual Com port, in my case it shows up as "COM13".
- I open HyperTerminal and connect to COM13 at 115200 bauds, 8 bits, 1 stop bit, hardware flow control
- If I type "AT" + ENTER, the phone answers "OK"
- If I type "ATI1" + ENTER, the phone answers with its model number "Platform: X.X.X.X, App version: X.X.X.X, PIN: XXXXXXXX"
- If I type "AT+CSQ" + ENTER, the phone answers with the current signal quality value "+CSQ: 21,99".
In theory it should be a piece of cake to query my phone using a serial port routine in VB.NET. The problem I have is that VB.NET allows me to read data from a REAL COM PORT, but refuses to read anything from a VIRTUAL COM PORT. When opening "COM13", I get "The given port name does not start with COM/com or does not resolve to a valid serial port. Parameter name: portName".
I did a lot a searching on Virtual Com Port on the WEB, but everything I see allows me to create a virtual com port. I only want to read an existing VIRTUAL COM PORT, not create a new one.So, I do I actually open a VIRTUAL SERIAL PORT, so that I can send the "AT+CSQ" command and receive my cell phone signal strength value using VB.NET?
Is there an easy way to just ping a server by IP or URL and return the minimum, maximum and average milliseconds? Actually the same results I get in CMD when using the ping command. Can't find any tutorial that describes it. So let's say I have a Textbox1 and a Button1 and a Label1 for the results. How can I do it?
View 1 RepliesOk basically what I am doing is using panels to create virtual "pages" within my application, and using buttons to switch from page to page. However whenever I click the button to move from page1 to page2, page 1 disappears and page2 does not become visible.
Private Sub page1_next_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles page1_next.Click
page2.Visible = True
page1.Visible = False
ToolStripStatusLabel1.Text = status_page2
End Sub
Also, how do I make it so that when the user focuses on a text box a tool tip pops up?

I have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?
Do I really have to go through all this just to find out what item has been selected in a ListView?
