Sadly I don't think it does do what I need. Basically I want the RichTextBox to display text, with the correct font, bold, background colour, etc, but to be transparent to mouse events such as double click.
I am able to intercept mouse double clicks in a class derived from RichTextBox, and SendMessage them to the parent form. They are passed in to the parent form WndProc. But for some reason they do not invoke the MouseDoubleClick event handler. I tried overriding the Form.WndProc, but could not invoke MouseDoubleClick, for reasons I understand.

Surely, because in Win32API, to be able to handle control's messages in parent window you have to send and process notification messages. For example, if you need to process MouseDblClick message outside the RichEditCtrl, first you have to handle this message in RichEditCtrl window class by posting WM_NOTIFY message and then process the WM_NOTIFY in the parent window as just I have shown in my reply.

How to do Automatically select the Next items of list box using Timer?
|
|
|
|
|
It depends on the UI technology you use, but for example if you use forms, you can create the timer and wire Tick[^] event. In the event, you set the SelectedItem[^] property.
|
|
|
|
|
Keep a class level index to the currently selected item, and either use it to set the ListBox.SelectedIndex property, or to pick the appropriate entry from the ListBox.Items collection.
In your timer Tick handler, you use the index and increment it.
What part of this is giving you difficulties?

if i click the button,list box items automatically go to next and display the image.Each image displayed at 10 second.
Timer t= new timer();
private void button_click(object ,Event )
{
for(int i=0;i<listbox1.items.count;i++)
{
if(i<=listbox1.items.count)
{
listbox1.SelectedIndex =i;
t.Tick += new System.EventHandler(showcurrentimage);
t.interval=10*1000;
t.start();
}
}
}
private void showcurrentimage (object , event)
{
picture.Load(listbox1.Selecteditems.Tostring());
t.sop();
}

Why are you adding a new tick event for each iteration round the loop?
You do realize that you will get a Tick event handler call for each time you add it?
Seriously, start by moving the timer setup code to your form load, and start it only once.

ok,how to use the Tick event with out loop? please show any example code
|
|
|
|
|
The whole idea of a tick event is that you don't need a loop!
Try an experiment: set up and start your timer in the load event, and make the tick event write to the console:
Console.WriteLine(DateTime.Now); Comment everything else out of the handler.
Run your app in the debugger, and look at the output pane. See what I mean?

Increase the SelectedIndex of the ListBox in the Timer_Tick event handler. Build in safeguard to reset index after last item in the list.

I'm sorry, but I can't understand but you are trying to say.
Try writing it in your native language as if you were describing the problem to your mother, and use Google Translate to get an English version. That should eliminate any technical terms, and give us both a description we can understand?

No, let's use text - that way others can also read it who may understand what you are saying better than I do. And we have quite a few other Chinese members who may see it and be able to help.
