What makes you think that? Here they are:
TrackBar.BeginInit[^]
TrackBar.EndInit[^]

The object doesn't change. After you cast an object it is still the same object. It is just the reference to it that is different.

No problem - we all have days like that from time to time.
Earlier this week I sent an email round the development team at work telling them about this work around I'd found to get around the fact that such-and-such menu item wasn't available in a certain project type in Visual Studio. One of the devs in our other office wrote back and said, "do you mean the 8th item on the so-and-so menu?". For a whole day I'd been ripping my hair out trying to figure it out and it was staring at me in the face. I replied the only thing I could reply: "This year I shall be mostly going slightly mad".
Also, in my uni' days I'd rip my hair out over compiler messages that I couldn't understand. I'd eventually find after several hours I'd missed a semi-colon. Luckily, today compilers are much better about point out missing semi-colons than the DOS version of Turbo C++ was.

((ISupportInitialize) this.pictureBox1).BeginInit();
Ok...there pictureBox1 is a PictureBox and does not implement those methods.
Can anyone explain?
My first example was a bad one.

In Framework 2.0 PictureBox implements both methods as explicit interface implementations; scroll down to the bottom of the following page:
PictureBox Methods[^].
Some information on explicit interface implementations can be found here: Explicit interface member implementations[^]

Well, this isn't the right place to ask this. Are you saying that you don't have a link to edit it ? I think it's the case that once an article is edited by one of our editors, you can no longer edit it, you need instead to email the edited text as a submission. That's my recollection. If you can provide some more details, perhaps I can help further.
Nope - all your articles are unedited. Which one is the problem ?

I was wondering if someone could help me with a little problem
I have a large multiline text box (8000 characters long) called txtComments, above it a button called btnSelectAll.
What I have been trying to do is, when the user clicks the button the text in the multiline text box is all highlighted.
This is part of a ASP.Net web project using C#
Many thanks for your help

So, you want to find some javascript that will select all the text ?
This[^] seems to cover it.

Is it better to use Javascript or can it be done in C#
Thanks

I'm confused why so many people seem to ask this sort of question. IF you want something to happen on the client, you need to use javascript. If it's possible to do using C#, it will involve an entire page postback, by definition. You can't write C# code for the client, only the server.

Dear Christian Graus
Many thanks for your reply, I've only been writing .net pages for 4 months, it's been a hard slog, I understand what you have said and shall look at a Javascript script to carry out the task
Thanks

You can add a char to a string. If you can't, that is stupid, but calling ToString on the char would then fix it.

Say I have a few buttons on an MDIparent form.
By pressing one of the buttons I activated an MDIchild from.
At this point I would like to know what kind of buttons or controls
the MDIparent form has.
Any help would be much appreciated.

You shouldn't ever be able to tell, as they hsould not be public. But, if they are, then it's easy to find out. Just grab the Parent property, and cast it to the specific type of the form class.
