scaling text to fit into rectangle misterbear31-Jul-03 4:13 misterbear 31-Jul-03 4:13  I have a little problem... I have a panel with controls on it, that i want to draw to the printer. the controls consist of smaller panels with text inside them, and listboxes with lines of text inside as well. (class diagram editor) Now the problem is that when I print this i scale it to fit to A4 (or whatever specified) paper size. No problem scaling a simple bounding rectangle to the textboxes and listboxes, but now I want the text to be printed inside these components as well, so the print-out will appear as on screen. How can i fit the text into these boxes, i.e. apply a scaling to the bounding rectangle of the text? I have thought of two things: Either change font size until something that fits is found OR Draw the text to a bitmap and scale this. Is there any 'standard' way of doing things like this?

Like: string Form = "Form1.text" + "=" + "Hello"; This string should now be executed directly, instead of doing Form1.text = "Hello"; Background is to rename buttons and forms.... Would be very helpful if somebody has a great Idea. Thanks Jörg Re: Convert string into expression Nick Seng31-Jul-03 15:34 Nick Seng 31-Jul-03 15:34  I would use the MS Script Control.

In your Form you can register delegate method for the UserControl event which will be responsible for event processing. T.

Re: running function in Form from UserControl Rampas Tomas3-Aug-03 21:34 Rampas Tomas 3-Aug-03 21:34  OK, here is the code snippet: First, in you CustomControl we define an event: namespace MyControlLibry { class MyControl : UserControl { public event MyControlEvent ModeChanged; public MyControl() { } // If user clicked on Insert button it cause trigger new ModeChanged event: public ButtonInsertClick(object sender, System.EventArgs ea) { if (myevent != null) ModeChanged(this, new MyCustomEventArgs("INSERT")); } } // function prototype public delgate void MyControlEventHandler(object sender, MyCustomEventArgs mcea); // custom event args public class MyCustomEventArgs: SystemEventArgs { private string stxt; public MyCustomEventArgs(string text) { stxt = text; } public string MyCustomText { get { return stxt;} set { stxt = value;} } } } Finally in you Form you must define event handler: public class MyForm : Form { private MyControl ctrl; public MyForm() { ctrl.ModeChanged = new MyControlEventHandler(CustomModeChanged); } // CustomModeChanged must have the same signature as delegate so public void CustomModeChanged(object sender, MyCustomEventArgs mea) { Console.WriteLine(mea.MyCustomText); } } Hope it helps Tomas Rampas ------------------------------ gedas CR s.r.o.

Re: running function in Form from UserControl Rampas Tomas4-Aug-03 3:38 Rampas Tomas 4-Aug-03 3:38  You have almost everything, but you have to add a couple of things: 1. You must provide definition for the MyCustomEventArgs (look at my previous exmple) 2. Define click event method for buttonNew button, and in this method call : private void buttonNew_Click(object sender, System.EventArgs se) { if(NewRecord != null) NewRecord(this, new MyCustomEventArgs()); } 3. According to me, it would be better to remove the delegate outside the class definition ( place it simply in dabir namespace ) 4. Finally in your form where you are using your custom control register the appropriate method with similar signature as the delegate have. //ArrowControl definition ArrowControl ctrl = new ArrowControl(); //Form construktor public MyForm() { ctrl.NewRecord += new MyControEventHandeler(NewRecordHandler); } public void NewRecordHandler(object sender, MyCustomEventArgs e) { // do appropriate things with new record } Tomas Rampas ------------------------------ gedas CR s.r.o.
