well, i thought this would work, but it doesnt..
this.cbCountyDefault.BeginUpdate();
for (int i = 0; i < m_saCountyRecords.Count; i++)
{
GASTCountyRecord objRecord = (GASTCountyRecord)m_saCountyRecords[i];
this.cbCountyDefault.Items.Add(objRecord);
}
this.cbCountyDefault.SelectedIndex = 0;
this.cbCountyDefault.EndUpdate();
MessageBox.Show(cbCountyDefault.SelectedItem.ToString());
MessageBox.Show(((GASTCountyRecord)this.cbCountyDefault.SelectedItem).ToString());the first messagebox shows the objects name, and the one where i cast it shows the corect name..
the listing in the combobox lists the class name because it populates this by calling Object.ToString() not by casting it to my object type then calling ToString().. any other suggestions?

hrm.. it was how i was doing it.. ill put this here for future reference
how not to do it:
public class GASTCountyRecord : object
{
public string m_strCode;
public string m_strName;
public GASTCountyRecord(string strCode, string strName)
{
m_strCode = strCode;
m_strName = strName;
}
public string ToString()
{ return m_strName; }
}
how to do it:
public class GASTCountyRecord : object
{
public string m_strCode;
public string m_strName;
public GASTCountyRecord(string strCode, string strName)
{
m_strCode = strCode;
m_strName = strName;
}
public override string ToString()
{ return m_strName; }
}
thanks for all your help.. i think the way they have you implement this is a bit wack tho

Hi.
WYSIWYG HTML Editors for webbased content managment systems have been around quite some time now. Personaly i love the free ASP.NET web control named "FreeTextBox", witch can be found at: SourceForge[^].
These days when more and more developers keep focusing on the power of the rich client, a HTML Editor Control for windows forms would be greate.
I was wondering if there where such a control around, where you could set up your buttons (witch type of HTML you would allow the user to create) and simply extract the html content. Are there inbuilt functions doing this in the RitchTextBox control?

Hello,I have got the appletElement by following:
mshtml.HTMLObjectElementClass applet=(mshtml.HTMLObjectElementClass)applets.item(i,i);
string altHtml=applet.altHtml;
to extract all anchors from the applet, a way is to process altHtml,I wonder whether has another way.
Thanks.;)

How do I detect when a dail up (or some other form of internet) connection is established?
|
|
|
|
|
I don't know the .NET BCL way to do it, but you could use InternetGetConnectedState[^] API. You can use it to find out whether you're connected, and what type of connection is currently being used (dial-up, LAN, whatever).

As part of my app, i've used reflection to load an assembly.
Assembly.LoadFrom(filename);
This works great. But I don't want the assembly to be bound any longer. I wish to modify/move/delete the assembly from the app. but now its bound and can't be modified.
Is there a way to 'unbind' an assembly?

You would have to load it in a separate AppDomain. Then when you unload the AppDomain, it'll unload the Assembly.

Right, firstly thanks for replying, it seems like the right was of doing it and after a bit of MSDNing, i've come up with some AppDomain code.
AppDomain appd = AppDomain.CreateDomain("Plugins");
foreach(Plugin File.....)
{
Assembly a = appd.Load(fileName);
}
OK this isn't all the code but its the only code that is failing. Basically the appdomain isn't loading the files. It throws the following:
File or assembly name <path>\plugins\Plugin.dll, or one of its dependencies, was not found.
For each of the plugin files I try to load. Now when it was trying to load the files in the main appdomain, it loads them fine, but now after trying what you said, I can't get it to load them. They are not bound anywhere else and the full path is given to the appd.Load() method.
Any ideas?

Look at my article on Plugin Automation, it will generate the necesary wrapper classes and Management classes for loading/unloading (note: not too handy when a plugin contains a form).
It will probably do exactly what you want to do

Is there any equivalent to the GetTextMetrics function in the .NET framework? I'm trying to find the height of a font (I know I can use the Height property of a Font object) including the leading, which the height property doesn't give. If there is no equivalent could someone post an example of how to use GetTextMetrics in C#.
Thanks all!

System.Drawing.Graphics.MeasureString()
Thanks, but that doesn't work. It gives the exact same value as using the Height property of the font. I think I'm going to have to end up using GetTextMetrics, but I don't know how to create the TEXTMETRICS structure that it needs in C#.
Any help is much appreciated.

I have the class MyText devived from RichTextEdit and I have inside and an other structure (System.Collection.ArrayList).
In the main form I open a TabControl and like pages I use this class .
In the new class I draw ellipses .When the TabPage lose the focus the draw disapear . I override OnPaint , where I redraw everything , but this override is not doing what is meent to do .
Hwo I make the drawing to be seen on screen (ClientRectangle).

tried using tapPage.Hide() but it has no effect, tab page still displays... I'm wanting to show a tabPage2 only when there are processing errors on tabPag1. Is there another way, or a way to dynamically add a tab page to a tab control...???
thanks,
vince

If the TabControl is named "tabControl" , the code for closing is :
// verify if the TabPages exist
// if we try to close a non-open tab will have error's
if (this.tabControl.TabPages.Count != 0)
this.tabControl.TabPages.Remove(this.tabControl.SelectedTab);
//SelectedTab is the selected tab tabControl.TabPages[<number>] is the
//<number> tab , if you whant other tab

thanks for the reply, but that's not quite what I'm looking for... I need to have either a hidden tab page that can be unhidden, or the ability to create a tab page with a listbox containing error strings...
Don't need to remove a tab page...
thanks for any further suggestions..

Sure, try something like this, it works:
for(int i = 0; i < 5;i++)
{
TabPage tbpage = new TabPage("test" + i);
this.tabControl1.TabPages.Add(tbpage);
}

I'm building a set of custom controls. I would like the controls to act as parents for controls dropped on them in the forms editor. I could use .Panel as the parent type but that would preclude visual editing in the IDE ( why ? ).
Looking at UserControl in the object browser I see that it is indeed a container and implements the IContainer interface somewhere down in the inheritance diagram. However, if I drop a UserControl into a form then drop another UserControl on top of it the forms editor will make the form the parent of both. This is different than if I drop the second UserControl on a panel or groupbox.
How do I make my controls act like a panel/groupbox in this respect ?

Answering myself.....add this class to your controls base class.
///
/// Provides Base class designer support.
///
public class YourBaseClassControlDesigner : System.Windows.Forms.Design.ParentControlDesigner
{
// add whatever filters you like to determine the types of controls you can parent
public override bool CanParent(Control c)
{
return true;
}
public override bool CanParent(ControlDesigner cd)
{
return true;
}
}
then add these attributes to your actual control...
[Designer(typeof (YourBaseClassControlDesigner))]
public class YourBaseClassControl : System.Windows.Forms.UserControl ...

Hi everyone,
I would like to create a control able to reproduce the navigation bar of Windows XP. I do not want to simulate what the original control does, I would like to exploit what Windows XP does (as I can do with every common controls). What kind of control is the original navigation bar?
Thanks in advance for your attention
