Now I can write functions like Delete( uint rowID ) in the base class, and via polymorphism they DELETE from different tables depending on what the type the instantiating class is.

This seems less clean to me than using static functions, but it does the job.

Please look how I did it in my code. I just a nice inherited Delete() function without any parameters. Look at the base class in the Interfaces.cs file (ok the filename is a bit dumb).

To do what you wanna do, will force you to rewrite the each fucntion (i have gone over this).

Best is to think about your whole design again. What you will designing if you succeed, will be some classes that cannot be reused in any way, destroying the concept of OOP. I ussually have to redesign a class structure 4/5 times to make it work in its most effecient way. So just go and sleep on the thoughts for the next few days.

You can mail me your code, I could have a look at the design, maybe some mistunderstandings will be cleared up.

I'm still working on a solution to this using readonly properties - and I might have to dirty my hands a little with Reflection (not sure yet). If you'd like I can send you my code so you can get some idea what I'm working towards.

Now I really dont want to know what you are trying todo with readonly properties. Laugh | :laugh:

TextBox DataBinding

leppie8-Mar-03 7:24

Hi all

I have bound a textbox to a field in a table. The problem is however that databinding does not occur until either control gets destroyed or it text is changed by moving to the next element. Now when I want to save the dataset to xml, I have to move to another element, before the changes are reflected.

How can I manually force databinding on a textbox?

Mazdak8-Mar-03 7:02

8-Mar-03 7:02

I have one treeview and one toolbar in my form.The toolbar has TOP DOCKING and I want TreeView has Left Docking.When I set the its docking it takes all of the left side of the form,and the form set the TOP DOCKING of toolbar at the second,so it does not take all of the top of the form and it start after hte TreeView,how can I change this,so Toolbar takes all space at the TOP,and TreeView start below it with Left DOCKING?

Make sure the toolbar is added to the forms control collection before adding the treeview. Poke tongue | ;-P

Have you tried using the System.Threading namespace and the System.Threading.Thread class? I believe those will give you what you want.

Viewing HTML in C#

Mazdak8-Mar-03 3:00

8-Mar-03 3:00

We had HTMLView in MFC,so we could browse web or HTML page in a view in a application(I think it refers to IWebBrowser ).Now do we have something like that in C#?I want my application show HTML or ASP pages inside itself,not open with IE.

I hope you don't think the MFC CHTMLView provides a full fledge rendering engine by itself. CHTMLView is only a IE wrapper, just like the IE wrapper you get by dropping the Web browser control onto a Windows Form.

Mazdak wrote:

I don't know if that's me, but that means pretty much nothing. Last month, ASP was still a server-side scripting engine providing facilities to build web pages that, once built, are sent to the client browser.

Yes,that works. Thanks. But I have a problem with it.When I click a link inside the control it open a IE and want to browse it in new window.Do you if I can prevent it?

Yes,you are right,I know it.I didn't want to browse ASP page in my application.It was just a mistake,I was typing quickliy and didn'r mention it.

Yes. Override OnNewWindow2 and OnBeforeNavigate2 and make sure to assign true to the cancel arg : e.Cancel=true, where e is the event handler arguments. This article[^] also shows how to properly handle new windows : in fact, you can create a new Form instance at such moment and create a new browser control instance there, so it behaves right.
