Add a TabControl to a form with a few Buttons under it. Add your UserControls to each tab. After compiling your project, the UserControls should be available in the Toolbox. If not, add them manually by adding a private field for each Type and instantiate them and initialize them in the InitializeComponent method that the Windows Forms designers use. It's not difficult and the designers aren't magic. Knowing how to add this stuff without a designer is essential in good development skills.

Hi,

Thanks for your post!

The solution you gave works well, but I was looking for something like CPropertySheet and CProperyPage in MFC.

Is there any control that we can use as placeholder for other controls?

Thanks again.

By the way, I like programming with the keyboard, not with the mouse Big Grin | :-D

That's not really what you asked for, though.

If you want a good implementation, see the IPropertySheet documentation in the Platform SDK on http://msdn.microsoft.com[^]. For example, I use a implementation similar to the following in our application:

public interface IPropertyPage
{
  string Title { get; }
  void Save();
  void Cancel();
  event PropertyChangedEventHandler PropertyChanged;
}

Implement this type of interface on your control. Then create a PropertySheet class that allows you to add IPropertyPage implementations to it. When you call ShowDialog on your PropertySheet (should derive from Form) it has all the pages in a TabControl. When the event is fired, enable the Apply button. When Apply or Save is clicked, call Save on each IPropertyPage in your collection and close the dialog if Save was clicked (it annoys me to no end when people click Apply then OK since OK is supposed to apply changes and close and - with all Microsoft implementations - does).

This is very similar to how MFC and the Windows Shell interfaces do it.

Treeview context menu remains visible

Hi All,

I have a Windows Forms app with a treeview control. I'm trying to add a 'Rename' command to the context menu. The event handler for the context menu looks like the following:

private void cmMTRename_Click(object sender, System.EventArgs e)
{
if (tvModelTree.SelectedNode != null)
tvModelTree.SelectedNode.BeginEdit();
}

The node goes into edit mode but the context menu stays visible. Is there a way to hide the context menu prior to putting the node into edit mode?

Thanks,
Chris

I was outsmarted by the tree control.

I was handling the MouseUp event to display the context menu. It seems the treeview already does this for me so I was displaying it a second time.

Thanks.

I've created an MSI installer with VS.NET 2003 which runs great. I've created two file type associations. The association is made, but when I right click on the associated file and view the proerites I notice something strange. The "File Type" information is correct = "My Prog File"
but the "Opens with:" data is not correct, it just shows the program icon and not the name. I've tracked it down to a registry entry:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\MUICache]
There is a registry string in there called:
"C:\Program Files\MyCompany\MyProgram Folder\MyProgram.exe"
the value for this string is blank. When I assign the value of "MyProgram.exe" to the entry, the associated file property page now reflect both the program icon and name in the "Opens with:" area.

Does anyone how this getts filled in ? Am I missing some kind of description property in my assemby ?

Any thoughts on how to fix this would be very much appreciated.

This question - since it's specific to the Glacial ListView - is better suited for the forum at the bottom of the article: http://www.codeproject.com/cs/miscctrl/aa_listview.asp[^].

Hello,

I am creating a toolbar for IE, almost like google toolbar. I want to give options for websearching, save current web page, and it should cofigurable from XML. I created a toolbar and it is visible in my IE, but I am struck in websearching part. Anybody please help me or give me the tips, how google and yahoo searches the web from its toolbar,and how can I implement it. please help me.

Thanks in advance for your time.

Are you asking about how to make the toolbar work? Or, what URL to send searches to? The latter is very easy: Just go to the search engine you want, type in something simple like "test". Then, after that gets submitted, copy the URL and replace the value you used with the search query. For instance, Google's would be: "http://www.google.com/search?q={0}".

from VB to C#

how can i convert code from VB to C#:
( i am new to c#)

Public Function GetHiWord(ByRef lparam As Integer) As Integer
' This is the HIWORD of the lParam:
GetHiWord = lparam \ &H10000 And &HFFFF
End Function
Public Function GetLoWord(ByRef lparam As Integer) As Integer
' This is the LOWORD of the lParam:
GetLoWord = lparam And &HFFFF
End Function

Thanks D'Oh! | :doh:

Michael Flanakin24-Mar-04 2:08

I believe this is right:

public int GetHiWord( int lparam )
{
    return lparam \ (0x10000 & 0xFFFF)
}
 
public int GetLoWord( int lparam )
{
    return lparam & 0xFFFF
}

I think it should be

GetHiWord(ref int lparam)

and

GetLoWord(ref int lparam)

since the value is being passed by reference rather than value type.

Michael Flanakin24-Mar-04 3:51

You're right. The only reason I didn't do that was because nothing was done with the value. I figured that, if it wasn't being changed, then there wasn't a reason to have the reference. I may be wrong tho.

But the VB code is also returning an Integer (it's a function, not a sub). IMO, the original VB code was flawed since it was taking an Integer reference but still returning a separate Integer without actually modifying the parameter value (hence, no need for ByRef and should've been ByVal instead).

Thanks,
There is no \ in c#
so i guess i should do:
public int GetHiWord( int lparam )
{
return lparam / (0x10000 & 0xFFFF); // or ? return lparam / 0x10000 & 0xFFFF;

}
public int GetLoWord( int lparam )
{
return lparam & 0xFFFF ;
}

good rescources on Sharepoint development

You're right. Good catch.

As for whether or not to use parens, I'm not sure which operator will execute first. I would suggest using the parens for clarity, just to make sure the point gets across.

Hi.

I'm new to the Sharepoint portal server 2003 (or any other sharepoint for that matter) and I need to get to know how to develop stuff for it.
I've messed around a bit with building webparts and now I want to know how to make custom lists.
However i'm having trouble finding any good rescources on the subject.
Is there anyone here that can point me to some good forums/guides/tutorials/SDK's/etc. ?

p.s. I have been through MSDN and I don't seem to be able to find anything other than developing webparts there.
