Now I know how!  
Thank you Mazy!

Thanks!
In fact, I have several user controls, each one with different controls inside. I would like to create a loop for each user control, to go through inside controls one by one, no matter how many in there, and what they are, try to set readonly to true, catch exceptions if there is no such property. But such as combobox, does not have this property, but I still need to set it to readonly, how can I do it, and do you think this loop methodoligy will work?
Thanks a lot!

I have an idea for a program that would run in the background and then, when the user presses the windows key (in any application), it would come to the foreground.
Anyone know how I can do this?

How to make Combobox, Radio buttons (group) read only?
Thanks!
|
|
|
|
|
I know that the RadioButton has an "AutoCheck" property. Setting that to "false" will make it so that the radio button won't change state when the user clicks on it.
I don't know how to make a ComboBox read only. Hopefully some of the more experienced developers will know.
Good luck.

Combo boxes are read-only by default! Even if they have that edit box on top [which is easily removed by changing the style], the actual contents of the combo cannot be changed. Of course if someone wants to make it un-clickable, he can make it disabled.

My problem is regarding the refresh of the controls in .net (tree view).
In MFC I had a tool that loaded up all the folders of a drive and there size. This was done with a tree view control, in the main loop where all the folders were read, after that the new folder was added to the control or any text was changed, I just process any pending messages and the end result was excellent.
But in .net when I do the exact same thing each time that I add a new node or change the text of an old node (to update the size of the folder) the entire tree view is redrawn, I get the nice flickering effect… I process any pending messages with the “Application.DoEvents()” function, is that my problem? Is it a property I have to change?? I mean why in MFC I didn’t have to take this in consideration but in .net I have to??? In MFC when I added a new node or change the text of a node it just updated that node.
I’m kind of disappointed.

Try enabling double buffering and see if that helps.
The cause of flicker is that you can see each part of the window being redrawn, starting with erasing the current contents. If you enable double-buffering all the drawing will be done off screen, then once the drawing is done it will draw that image to the screen.

Thanks...
Did MFC had the double-buffering embedded in the controls? I never heard of double-buffering for MFC controls and they never flickered...

Don't know, both are wrappers around the Tree control provided by Windows so I would assume it wouldn't interfere too much.

I'm disappointed that I have to do extra stuff in .net to make the control look as they usually looked...
|
|
|
|

If you are adding many items, try using the BeginUpdate and EndUpdate methods on the TreeView.
|
|
|
|

It would work, but I want to see the list grow because I can take a while to read all the folders on a drive and I want browse them while the rest is loading.

I have an app that does something similar, and I think it's a lot nicer to load-on-demand rather that fill in the full control. To do this, you need to put a "pretend" node underneath each directory and then handle the expand event.

Hi,
How do I create a COM component in C~ when i know the CLSID of the component, this CLSID is discovered in real-time so i can not add a reference to the DLL at compile time.
Cheers
|

The answer is....
Type comType = Type.GetTypeFromCLSID( new Guid( "12345678-0000-....") );
object comObj = Activator.CreateInstance( comType );
// if you have type infos (tlbimp/reference), try to cast:
YourCOMClass yourObj = (YourCOMClass) comObj;
// or for some special imported types, wrap:
// YourCOMClass yourObj = (YourCOMClass) Marshal.CreateWrapperOfType( comObj, typeof(YourCOMClass) );
To access remote by DCOM:
Type dcomType = Type.GetTypeFromCLSID( guid, "REMOTE_PC", false );

In your properties set function, set all the child controls according to what they have set the property to.

The framework won't do this, this is something that needs to be done on a case-by-case basis because ReadOnly doesn't make sense to everything (progress control for example).
Also you need to keep in mind that ReadOnly is only a UI state, code can still read/write to the controls, the controls just don't accept user input.
With those ideas in mind...
private bool isReadOnly = false;
public bool ReadOnly
{
get
{
return isReadOnly;
}
set
{
isReadOnly = value;
textBox1.ReadOnly = isReadOnly;
}
}Good Luck,
James

In the .net framework is there a function that would process any pending messages in the message queue for the current thread, so while reading folders from a hard drive I could still move the window around.
Thanks
