Unwanted Main form minimalization

Hello,



I have a following scenario:



I have two forms: Main and SplashScreen. The splash I show in Main
constructor. In Main_Load() method I hide the main form, than do an
application initialization (data connect etc). After that I hide the Splash
screen and Show the main form. Everything is ok, provided I don't show any
dialog to the user while the main form is hidden. When I do it (e.g. "The
data connection could not be established"), the main form shows minimalized.
I reproduced the problem in the end of this post.



Help much appreciated.

Regards, m.



I have two forms, Form1.cs and Form2.cs:

// -------------------------------------------------------------------------

// Form1.cs

using System;

using System.Drawing;

using System.Collections;

using System.Windows.Forms;

using System.Data;

namespace FormInBackground

{

/// <summary>

/// Summary description for Form1.

/// </summary>

public class Form1 : System.Windows.Forms.Form

{

private System.Windows.Forms.OpenFileDialog openFileDialog1;

Form2 Splash = new Form2();

public Form1()

{

Splash.Show();

Splash.Refresh();

//

{

}

#region Windows Form Designer generated code

/// <summary>

/// the contents of this method with the code editor.

private void InitializeComponent()

{

this.openFileDialog1 = new System.Windows.Forms.OpenFileDialog();

//

// Form1

//

this.ClientSize = new System.Drawing.Size(170, 87);

this.Text = "Form1";

this.Load += new System.EventHandler(this.Form1_Load);

}

#endregion

/// <summary>

static void Main()

{

Application.Run(new Form1());

}

private void Form1_Load(object sender, System.EventArgs e)

{

this.Hide();

// MessageBox.Show("With this Message Box Form1 runs minimized.");

Splash.Hide();

this.Show();

}

}

}

// End of form 1

// -------------------------------------------------------------------------

// Form2.cs

using System;

using System.Drawing;

using System.Collections;

using System.ComponentModel;

using System.Windows.Forms;

namespace FormInBackground

{

/// <summary>

public class Form2 : System.Windows.Forms.Form

{

private System.Windows.Forms.Label label1;



public Form2()

//

this.label1.Font = new System.Drawing.Font("Microsoft Sans Serif", 12F,
System.Drawing.FontStyle.Regular);

this.label1.Location = new System.Drawing.Point(24, 24);

this.label1.Size = new System.Drawing.Size(72, 32);

this.label1.Text = "Splash";

//

// Form2

//

this.ClientSize = new System.Drawing.Size(122, 71);

this.Controls.Add(this.label1);

this.Text = "Form2";

}

#endregion

}

}

I have a following scenario:

I managed to get with it with Peter Foot's suggestion:

public void SetForegroundWindow()

{

this.Capture = true;

IntPtr hwnd = OpenNETCF.Win32.Win32Window.GetCapture();

this.Capture = false;

OpenNETCF.Win32.Win32Window.SetForegroundWindow(hwnd);

}

when I call it after this.Show(), the form actually shows.

Thanks Peter.

Regards, m.
