I'm building a listview search feature in my app. (See the code below). It works really well, except if you search "T" then the code removes all items, if you search "t" then it removes every item except for those starting with "t". Is there any way to make a 'like' statement, or use some kind of wildcard to make the statement not case sensitive?
For Each itm As ListViewItem In ListView2.Items
If itm.Text Like TextBox1.Text & "*" Or itm.SubItems.Item(1).Text Like TextBox1.Text & "*" Then
Else

I am handling many of the BindingNavigator tasks (MoveFirst, MoveNext, etc.)in code to ensure that I always ask the User to save his changes.
The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.

I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.

I'm using VB.NET to perform a SIMPLE record update. I don't understand why this is not working. Perhaps it's because the form is open while executing? I'm not sure. I'm using an Access backend.

I have been researching all that is related to DataSources, DataReaders, DataAdapters, etc, with an Access 2010 DB bound to a DataGridView.
Everything is fine, just one line fails and is driving me nuts Here is the code:
[Code]...
The line that fails, actually updates my database, but somehow, the update is not performed on the line that belongs to the first row of the grid. What is more, if I change the value manually, the same update method works fine. What is going on here?

I currently have a problem attepting to update a record within my database. I have a webpage that displays in text boxes a users details, these details are taken from the session upon login. The aim is to update the details when the user overwrites the current text in the text boxes.I have a function that runs when the user clicks the 'Save Details' button and it appears to work, as i have tested for number of rows affected and it outputs 1. However,when checking the database, the record has not been updated and I am unsure as to why.I've have checked the SQL statement that is being processed by displaying it as a label and it looks as so:
UPDATE [users]
SET [email] = @email,
[firstname] = @firstname,

I have the following code which works fine;
For Each myFile As String In IO.Directory.GetFiles(Label1.Text, "*.zip")
Dim fi As New System.IO.FileInfo(myFile)
sFilename = fi.Name
Col_Prac_no = sFilename.Substring(1, sFilename.IndexOf("_") - 1)
For example: I have filename as:
I00018_20120329042035_111
The col_prac_no = 00018
Now, I want to update the for statement to have another value extracted from the filename.
The first letter of the filename. In the example:
I00018_20120329042035_111
The first letter of the filename in above example is I.
So if we have:
S00018_20120329042035_192
the value will be - S.

Basically I am trying to update each record with 2 random numbers each time the button was clicked,my problem now is, the system will update the record but the data was wrong. Example, by right all data should be different (randomly string) but for some row it was updated with same data but in randomly, something row1 row2 row3 has exactly same data for column 1 and 2 then row 3 has distinct data, second time, row1 row2 same data row3 ro4 with different data. It is in random sequence. When I add a MsgBox to do testing in the For loop the data was updated correctly with all different data.
