The advice you were given is sort of right.
If you create new instances of Form1 and Form2, they will not relate in any way to instances that are in use in your app, so the call will do nothing, you need to use the instances that are in use, I assume you're in form1, and you want to call form2, in which case, you need the instance name for the Form2 instance, and drom Form1 entirely from the code snippet.
Your text box controls are also probably private, and instance of changing that, you should add properties that set the text of the textbox to the controls.
Also, I assume these are not your actual variable names ?

I want to be able to check which control the focus is moving to, when a particular control is losing the focus.
Bascially, I have a text box, that when you type into it displays an autocomplete list. If the focus is moving away from the text box to some other control, I want to hide the list. However, if its moving TO the list, then obviously it needs to stay shown.
There doesn't seem to be anything in the .Net events that indicate where the focus is moving. Is there perhasps a message I can send that discovers it?
Thansk in advance

Thanks for all your non-replies  I seem to have found out how to do it..
The easiest way is to in the OnLostFocus event handler, to first call the base.OnLostFocus. When control returns to your code, whichever control the focus has moved to will now have its .Focused property = true.
<br />
protected override void OnLostFocus(EventArgs e)<br />
{<br />
base.OnLostFocus (e);
if (!autoCompleteBox.Focused)
autoCompleteBox.Hide();<br />
}<br />
Regards,
Phil

If you just want to hide/show the autocomplete list, you can use
event Enter and Leave from the textbox to detect GotFocus/LostFocus

Hello
Well! I was just typing that answer when you modified your post!!?
Anyway, I still want to add that if you are using .Net 2.0, you should use the TextBox.AutoCompleteSource property instead, which is a built in AutoComplete.

Hi Nader,
Yes, unfortunately this does for now need to be supported in .Net 1.1, and I don't really want to maintain two code bases.
Thanks for your reply though.

I've looked everywhere. I've played with the Microsoft SGML component. I've played with the .NET wrapper of the COM wrapper of Tidy HTML. I've even thought of porting my 10 year old C++ HTML parser and correcter I wrote while bored over to C#.
But I'd rather just beg, borrow or steal (or even, and I'm this desperate) buy a .NET component That Just Works.
Does anyone have any recomendations?

They both use SGMLReader, and unfortunately the implementation as it's provided HTML-encodes already encoded HTML entities within PRE tags.
ie
<pre>
>
</pre> Comes out as
<pre>
&gt;
</pre> I'm beyond patience with trying to cobble together bits and pieces. I just want a simple, effective, efficient, thread safe component with one method:
public string HtmlCleaner.ConvertHtmlToXhtml(string inputHtml);
It's gotta be out there somewhere...

I appreciate the thought but you've just demonstrated the issue at hand: if you're looking for a .NET component to convert HTML to XHTML then you're very, very limited in your choices.
I'll just slap SGMLReader into shape.

I think Html Agility Pack is related to the one at eggheadcafe, it handled the entities ok but other than a quick test I haven't used it.

is it possible.........!

To a point. Mono is what you need, google Mono Linux and you'll find all the info you need.

Yes. As Christian said you can use Mono, or you can port your .NET code to J2EE (and continue to write and debug in your .NET language) using Grasshopper from Mainsoft[^]

i prefer to know that in c# only what is the classes in .net that access hardware of the pc

If you google for C# USB, you'll find there is no direct support ( I believe ), but some helper classes exist that use p/invoke.

Pretend myControl inherits from System.Windows.Forms.Control.
I'm trying to set myControl.BackColor to Color.Transparent in myControl's constructor so I can see stuff I've painted behind it. When I uncomment this command, the program hangs at startup (right at that line).
What's wrong with what I'm trying to do? Is it waiting (or looking) for something?

Instead of setting the background color to Color.Transparent in the constructor, I tried setting it to Color.FromArgb(0,0,0,0), which I've heard is transparent also (because of the 0 for Alpha). That didn't work either.
When I removed that line from the constructor and put it in a button event handler, after clicking the button, it gave me an ArgumentException, saying, "Control does not support transparent background colors."
I want to have a number of controls at dynamic locations on a panel, and be able to see through one control to another (the "controls" should just be a center dot and a circle inscribed in the control's bounds--hence, I want to be able to see one control's ring through another overlapping control).
Can someone please point me in the right direction? Should I be using a different base class (other than Control)?
I don't want to just paint to the parent panel, I want to actually have controls of some kind on the panel...

Hello
I've just done that and it throws an exception:
System.ArgumentException was unhandled
Message="Control does not support transparent background colors."

This is pure genius. You need to derive a class from the control type, so you can call SetSTyle ( a protected method ) and set the AllowTransparentBackground style ( or something like that ).

I did a little reading. For what I want to do, it won't quite work because MSDN says this:
Note:
If there is another control between the control
and its parent, the current control will not
show the control in the middle.
MSDN says it's because it's not a real transparency... it's the control asking its immediate parent to draw itself onto the control (simulating transparency), but ignoring other possible controls between the control and its parent.
Oh, well. If it weren't for the fact that I need to see through all the controls (not just the panel under one control), it would be fine.
I might just have to draw to the panel after all (instead of adding controls to the myPanel.Controls collection).
Thanks anyway! At least I learned why it was throwing an ArgumentException!
