I am looking for any information about how I could subcass a form I don't
own and resize some buttons.
We run a application which is extreamly legacy and the company has long
since went out of business. This application will install on WinXP but the
buttons on the form are smaller than they should be. I would like to hook
into this form and resize the buttons. I remember working on things like
this a few years back with VB but its been a while so any help or sites
would be appreciated.

I don't know of any sites, but what you might try is to use FindWindow
to find the window handle of the control in question such as a button.
Then use SendWindowPos api to change its size.
I'm not sure this will work and after you resize the button, if that
form is ever repainted, the button may go back to its former size.
Hope this helps a little.
Good Luck.

You probably don't need to do any subclassing just to resize controls.
You should be able to do that with the FindWindow(Ex) and MoveWindow
Win32 APIs.

Hi,
If you want to stay in the managed arena you can get the control references by
doing the following:
class DerivedForm : ParentForm
{
public DerivedForm()
{
// assuming that one Button.Name is "button1":
Button button1 = (Button) Controls["button1"];
// and just use the reference like normal
button1.Locatio n = new System.Drawing. Point(0, 0);
}
}
If you are unsure of the names of the buttons then place a break point on the
first line and exam the Controls collection in a watch window.
Of course, I'm assuming with this code that the base constructor will have
initialized the Buttons already, which is probably good since the designer
serializes initialization into an InitializeCompo nents method that will have
executed already in common scenarios.

That probably won't help the OP since he was specifically asking about
a form in another app, not created by him.
Hi Chris,
Yes, it seems that way now. I assumed that the OP might be using a Form from
a third-party assembly. "a form I don't own" is a bit vague and I read the
remainder of the post as referencing this third-party Form - a bit strange, I
know :)

I'm using v2.3, and trying to write to text files, but with a maximum

What is 'interprocess subclassing'? To give more context, I am writing
