multiple classes
Feb 22 2017 1:48 PM
Hello,
I want to build a multiple class aplication containing a picturebox.
I want to call OnPaint-Event in this application.
During the debugging-execution I get the error-message "StackOverflowException was not managed"(Form1.Designer.cs; this.ResumeLayout(false)).
my code is the following:
Form1.Designer.cs
namespace
WindowsFormsApplication1
{
partial
class
Form1
{
///
/// Erforderliche Designervariable.
///
private
System.ComponentModel.IContainer components =
null
;
private
void
InitializeComponent()
{
this
.pictureBox1 =
new
System.Windows.Forms.PictureBox();
((System.ComponentModel.ISupportInitialize)(
this
.pictureBox1)).BeginInit();
this
.SuspendLayout();
//
// pictureBox1
//
this
.pictureBox1.Location =
new
System.Drawing.Point(12, 25);
this
.pictureBox1.Name =
"pictureBox1"
;
this
.pictureBox1.Size =
new
System.Drawing.Size(268, 229);
this
.pictureBox1.TabIndex = 0;
this
.pictureBox1.TabStop =
false
;
//
// Form1
//
this
.AutoScaleDimensions =
new
System.Drawing.SizeF(6F, 13F);
this
.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this
.ClientSize =
new
System.Drawing.Size(292, 266);
this
.Controls.Add(
this
.pictureBox1);
this
.Name =
"Form1"
;
((System.ComponentModel.ISupportInitialize)(
this
.pictureBox1)).EndInit();
this
.ResumeLayout(
false
);
}
public
System.Windows.Forms.PictureBox pictureBox1;
}
}
Form1.cs
using
System;
using
System.Drawing;
using
System.Windows.Forms;
namespace
WindowsFormsApplication1
{
public
partial
class
Form1 : Form
{
Form2 itsme;
public
Form1()
{
InitializeComponent();
itsme =
new
Form2();
}
}
}
Form2.cs
using
System;
using
System.Drawing;
using
System.Windows.Forms;
namespace
WindowsFormsApplication1
{
class
Form2 : Control
{
Form1 itsme2;
public
Form2()
{
itsme2 =
new
Form1();
itsme2.pictureBox1.Paint +=
new
System.Windows.Forms.PaintEventHandler(
this
.OnPaint);
}
private
void
OnPaint(
object
sender, PaintEventArgs e)
{
MessageBox.Show(
"Hi"
);
}
}
}
If you can help me, many thanks.
