Re: After editing a dataset my changes are not visible in the datagrid sam#9-Jul-07 1:59 sam# 9-Jul-07 1:59  use dataGrid1.Refresh() still not working... kudorgyozo9-Jul-07 2:10 kudorgyozo 9-Jul-07 2:10  This doesn't work either. I don't think that i get no changes because i need to make refreshes.. but i don't know what else should i do or what am i doing wrong. -- modified at 8:17 Monday 9th July, 2007 Re: After editing a dataset my changes are not visible in the datagrid sam#9-Jul-07 2:21 sam# 9-Jul-07 2:21  sorry!! i didn't see your code.there are two mistakes. 1. Firstly when you added Column you specified their Type as Boolean and now u r changing the values. 2.when you assign the data source property with out making any table style structure it automatically generate table style for it. put DataGrid1.TableStyles.Clear() before reassigning data source and then use refresh Re: After editing a dataset my changes are not visible in the datagrid kudorgyozo9-Jul-07 2:35 kudorgyozo 9-Jul-07 2:35  I forgot to mention that i tried with "System.String" too instead of "System.Boolean" but it didn't work either.(used both true as boolean and "true" as string) I'm sorry but i didn't quite understand where should i put that DataGrid1.TableStyles.Clear(). After i add the rows to the dataset and before the 'for' cicle.

Status 500 is the catch all "something is wrong with the server" error, so without more information there is little we can help you with.

Software_Specialist9-Jul-07 0:27 Software_Specialist 9-Jul-07 0:27  Hiya all, Is it good practice to use NUnit Testing..?? What are the advantage n disadvantage of using Nunit testing.. Well i dont think its good if the application is not that big. Anyway i would like to know the experienced developers comment on this.... Thanks Re: Nunit Testing...?? Pete O'Hanlon9-Jul-07 0:48 Pete O'Hanlon 9-Jul-07 0:48  It's unit testing with NUnit and not NUnit testing. (A subtle, but important distinction because there are other unit testing frameworks). This is a large topic, and I will attempt to give you a succinct answer which explains why I use it on all projects. NUnit (and other frameworks) allow you to write repeatable tests. If you change your code, simply rerun the tests and check that you get the correct values. This all depends, of course, on your unit tests actually testing your code effectively. Now, this is all well and good, but where NUnit (and the other frameworks) comes into its own is with Test Driven Development (TDD). This approach means that you write unit tests before you actually write the code. You then build up your code and unit tests little bit by little bit until you can prove that the code works properly.

[modified] Abdul Gafoor9-Jul-07 0:25 Abdul Gafoor 9-Jul-07 0:25  Hi all, I want to handle a unhandled exception thrown by a plugin running in its own appDomain (ie not Defualt appDomain) in defualt appDomain (host appliation), and then unload the culprit appDomain.. Is it really possible to handle this kind of cross appDomain exception. the exception may occur any time during the life time of plugin appdomain ( say some buttton in the plugin throws some unhandled exception..) please have a look on the sample code given below.. What should i do handle the exception thrown by button1.. I never want to close my host application at any cost. it should continue its execution whatever happens in plugins.. please give me guide lines. //********************* Plug in ******************************* public class BadPlugin: Form,IPlugin { private System.Windows.Forms.Button button1; public StaffList() { InitializeComponent(); } private void InitializeComponent() { this.textBox1 = new System.Windows.Forms.TextBox(); this.button1 = new System.Windows.Forms.Button(); this.SuspendLayout(); // // button1 // this.button1.Location = new System.Drawing.Point(232, 96); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(176, 48); this.button1.TabIndex = 1; this.button1.Text = "button1"; this.button1.Click += new System.EventHandler(this.button1_Click); // // StaffList // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(488, 302); this.Controls.Add(this.button1); this.Controls.Add(this.textBox1); this.Name = "StaffList"; this.ResumeLayout(false); } private void button1_Click(object sender, System.EventArgs e) { throw new Exception("Bad plgin exploded exception"); } } //********************* Plug in Interface ******************************* public interface IPlugin { void Show(); } //******************** Plug in Host Application*************************** try { AppDomain app = AppDomain.CreateDomain("PluginDomain"); IPlugin plugin = (IPlugin)app.CreateInstanceAndUnwrap("SamplePlugins","SamplePlugins.BadPlugin"); plugin.Show(); } catch(Exception ex) { MessageBox.Show(ex.Message); } Thanks and regards 123developer -- modified at 1:06 Tuesday 10th July, 2007 Re: Cross AppDomain Exception Handling.

Abdul Gafoor9-Jul-07 1:18 Abdul Gafoor 9-Jul-07 1:18  Dude, I already had a look on AppDomain members.. if u r pointing to AppDomain.UnhandledException event.. , it is not firing in my case. I have registered this event bfore Application.Run().. in defualt appDomain.. According to MSDN documents, it sholud be fired before the application going to unstable state.. But in my case i am getting the unhanled exception message runtime messagebox.. What i am really missing my code. can you point the specific member you are suggesting. Thanks and regards 123developer
