Hi, TabIndex property is supported since .NET CF 2.0 (i.e. VS 2005).

I know with regular windows forms you can set the tab order by going to view on the menu bar and then click tab order. It will number all the controls and you can renumber them. I don't know if that same feature works with the compact framework. I would think it would.

Hi, does anyone know where i can get coding or just info on the classes and methods of the Tamir library?? I recently acquired it and cannot utilize it until i know exactly whats going on with it. My other question is does anyone know how to set up and send files over a sftp protocol with linux and windows (in C#) in a similar fassion.

P.S Iv never worked with sftp or ftp on a coding level so any assistance you could give me would be greatly appreciated.

What does this component do? Where did you get it? Without this information, there's not a lot I can do.

Deja View - the feeling that you've seen this post before.

I just found it is part of an example on sourceforge. But its not as important as finding out how the sftp works, necessary lib's and especially lin/win compatability. So regardless of this lib file that someone created, how do i sftp??

Data Grid problem

Hi I am developing a windows application (VS 2003) in which it contains some buttins and a grid. The Grid has to show all the data from a csv file, for this i am reading all the data from csv file into datatable and giving that datatable as a datasource to data grid.

dtTable = new DataTable();
dtTable.Columns.Add("Name");
dtTable.Columns.Add("Time1");
dtTable.Columns.Add("Time2");
dtTable.Columns.Add("Path");
dtTable.Columns.Add("IconName");
dtTable.AcceptChanges();

if(File.Exists(Application.StartupPath + "\\Recordings.csv"))
{
StreamReader sreader = new StreamReader(Application.StartupPath + "\\File.csv");
string strval = sreader.ReadLine();
while (strval != null)
{
DataRow row1 = dtTable.NewRow();
string[] str = strval.Split(',');
for(int i = 0; i < str.Length; i++)
{
row1[i] = str[i];
}
dtTable.Rows.Add(row1);
strval = sreader.ReadLine();
}
dtTable.AcceptChanges();
sreader.Close();
// }
dtGrid.DataSource = dtTable;
dtGrid.Refresh();

I am using the above code for showing the contents of file to Grid.

if user clicks start button on the form, after completing the action i want to add a row to grid. For this i am writing the new row to the CSV file and calling the above code.

But it is giving error: "Controls created on one thread cannot be parented to a control on a different thread."

Any one please help me.
Thanks in Advance

You need to always deal with your controls in your main thread.

use an event to trigger the creation of your control on the main thread, or use this.InvokeRequired to force you control to be created on the main thread

How do you define your connection string?

*shudder*

Don't! Learn how it works and don't rely on wizards.

Somewhere there should be generated code that contains the connection string. Alter that to get the connection string from the config file.

WPF Top level exception handling problem

Keith Barrow12-Aug-07 23:09

12-Aug-07 23:09

I have a WPF problem, namely my GUI top level exception handler doesn't:

<br />
public partial class ApplicationWindow : System.Windows.Window<br />
{<br />
  public ApplicationWindow()<br />
  {<br />
    InitializeComponent();<br />
    AppDomain.CurrentDomain.UnhandledException += <br />
    new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); <br />
 }<br />
<br />
  void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)<br />
  {<br />
    // Some stuff here that writes to event log*<br />
  }<br />
}<br />

* The code that I've removed from here works when CurrentDomain_UnhandledException is called sucessfully. Also I have try catches round all my top level execution blocks.

The problem I get is intermittant, and has only happened on the live machines Frown | :(

. When I look at the event log, the CurrentDomain_UnhandledException isn't called (there is no event log entry), but I get a .net 2 runtime error:

EventType clr20r3, P1 gui.exe, P2 1.0.2768.23782, P3 46af354c, P4 system.servicemodel, P5 3.0.0.0, P6 4545a17d, P7 109, P8 b0, P9 2ekkxphpp1te4kvupcgmdwsnjepb3jzg, P10 NIL.

I know the error must be from WCF which is referenced by the GUI and have put pretty decent exception trapping in my client code. I really need to know how to capture the execption at the top level in the GUI (have I missed anything?).

Thanks.
