Question

I have a borderless form that I would like to change the location of programmatically. I have tried a couple of different things and nothing seems to work. What is odd is if I go into the properties for the form, manually change the location to 100,100, set the StartPosition to manual, it still starts at 0,0. Another note is that the form only has one control and it’s a Flash player control. I’m not sure if that has anything to do with it. Any thoghts on why it wouldn’t move the window?

Answer 1

Change the location through the Load event of the Form.

void Form1_Load(object sender, EventArgs e)
{
    Location = new Point(400, 600);
}

EDIT1: posting a full example, in response to the author’s comment. This works correctly for me.

Form1.cs

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        var flash = new AxShockwaveFlash();
        Controls.Add(flash);
        FormBorderStyle = FormBorderStyle.None;
        StartPosition = FormStartPosition.Manual;
        Location = new Point(400, 600);
    }
}

Form1.Designer.cs

partial class Form1
{
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }

    /// <summary>
    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>
    private void InitializeComponent()
    {
        System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(Form1));
        this._axShockwaveFlash = new AxShockwaveFlashObjects.AxShockwaveFlash();
        ((System.ComponentModel.ISupportInitialize)(this._axShockwaveFlash)).BeginInit();
        this.SuspendLayout();
        // 
        // flash
        // 
        this._axShockwaveFlash.Enabled = true;
        this._axShockwaveFlash.Location = new System.Drawing.Point(0, 0);
        this._axShockwaveFlash.Name = "_axShockwaveFlash";
        this._axShockwaveFlash.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("flash.OcxState")));
        this._axShockwaveFlash.Size = new System.Drawing.Size(192, 192);
        this._axShockwaveFlash.TabIndex = 0;
        // 
        // Form1
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(486, 299);
        this.Controls.Add(this._axShockwaveFlash);
        this.Name = "Form1";
        this.Text = "Form1";
        ((System.ComponentModel.ISupportInitialize)(this._axShockwaveFlash)).EndInit();
        this.ResumeLayout(false);
    }

    #endregion
