Did you disable "Enable XP Visual Styles" in your project properties, Application tab?
If this option is greyed out, you turned off "Enable application framework", which will also disable XP Visual Styles.

u have right
the problem was that i converted the project from vs.net 1.0 to 2.0
so by default the XP style was set to don't

What's the rest of the error message? Is this problem comming up on your development machine, or is it on a machine that you deployed your app to?

Hello,
VS 2005
I want to create a user control for the compact framework.
I have developed user controls before, however I need to create a control based on the CF tab control. Currently the tabs always display at the button of the control. The customer wants them to be at the top of the control.
Would I have to create a user control that inherits the CF tab control? And maybe override something that would enable the tabs to be at the top
I have experience in creating user control, but nothing as complex as this.
Can any one provide any suggestions or sample code to get started.
Many thanks in advance,
Steve

I would generally try deriving from the control in question and see if it's a simple fix, or if the control is going to fight your change. Often, it's easier to start from scratch.

This is begging for a SQL attack, you should use parameterised queries, or, better yet, stored procs.
Colin has an excellent article on SQL injection, you should read it.
In C#, you can do this:
string sex = (rdoMale.Checked) ? "Male" : "Female";
Does VB do something like that ? Basically, it depends on how your data is stored, if it's a bool use the check result of the appropriate button. Otherwise, you need to build your paramater based on radio button state.

Hi,
I have implemented virtual mode alright, but i guess that makes the automatic sorting of DataGridView disable. Does anyone know how to implement sorting with Virtual mode?
Thanks

I haven't tried it, but I don't think you can do this without requerying the database for the sorted record set. Virtual mode doesn't load the entire dataset all at once so I don't think it can sort what it doesn't know about.

error I got is "no value given for one or more required parameters"
in cmd.CommandText, I tried <"SELECT Res FROM WordList WHERE Src='" & mtxt & "'">, and tried <"SELECT Res FROM WordList WHERE Src='test'">, both doesn't work
but it runs fine if I use <"SELECT * FROM WordList"> but this is not what I wanted.
Here's my code
Dim conn As New OleDb.OleDbConnection
Dim cmd As New OleDb.OleDbCommand
conn.ConnectionString = "Jet OLEDB:Global Partial Bulk Ops=2;Jet OLEDB:Registry Path=;Jet OLEDB:Database L" & _
"ocking Mode=1;Data Source=""dictdb.mdb"";Jet OLEDB:Engine Type=5;Provider=""Micr" & _
"osoft.Jet.OLEDB.4.0"";Jet OLEDB:System database=;Jet OLEDB:SFP=False;persist secu" & _
"rity info=False;Extended Properties=;Mode=Share Deny None;Jet OLEDB:Encrypt Data" & _
"base=False;Jet OLEDB:Create System Database=False;Jet OLEDB:Don't Copy Locale on" & _
" Compact=False;Jet OLEDB:Compact Without Replica Repair=False;User ID=Admin;Jet " & _
"OLEDB:Global Bulk Transactions=1"
' ^ Connection string copied from wizard, so this line is fine
conn.Open()
cmd.Connection = conn
cmd.CommandText = "SELECT Res FROM WordList WHERE Src = ?" 'I think error must be from this line
cmd.Parameters.Add(New OleDb.OleDbParameter("", mtxt)) 'or from this line
Dim rdr As OleDb.OleDbDataReader = cmd.ExecuteReader(CommandBehavior.CloseConnection) 'error was thrown in this line at ExecuteReader
rdr.Read()
txtRes.Text = rdr.GetString(0)
rdr.Close()
Anybody know what's wrong?
Thanks in advance

Have you two columns named Res and Src in your table?
If the answer is Yes then try to surround, in you query, those column names with square brackets, i.e. [Res], [Src].
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

That sort of subject is not helpful, it doesn't describe your problem at all.

To do this, use System.IO.File.ReadAllText to read the file, modify it in memory, then use File.WriteAllText to save it again.

Why not? Just create a temporary file with the new list of wanted words, rename the original first file, and rename the temporary file to the original name of the first file...
