picturebox transparency malfunction

[EntryTeam]

I'm writing turn based logic game, and transparency doesn't seen to work right:

Person model is .GIF in picturebox, buildings are .GIF in pictureboxes, mainform background is .bmp file.

Model picbox and building picboxes both have

.BackColor = System.Drawing.Color.Transparent;

...set.

How do I get this working as it should be?

You don't. It is the nature of a picturebox backgroundcolor to show through to the background color of the control underneath it.

if you put a picturebox on a form whose background color is red, then your picturebox background color is red.

A Form's background color of transparent will work as you are expecting. So instead of making a bunch of pictureboxes on a form you can make a bunch of forms with no border and transparent background and a background image.

This is why it is good to do small-scale experiment to prove one's assumptions before doing the BIG part of the coding.

@tlhintoq
You mean real forms instead of pictureboxes? How's that?

@tlhintoq
Can you get away with using a panel instead of a Form?
Transparent forms has been a big mess (if you look through post history here in bytes, there's been a few long threads about getting it to work)

A panel might work. I don't think I've tried for a purpose such as EntryTeam is doing.

Sounds like a good experiment.

EntryTeam: Give it a try. Instead of a bunch of picturebox controls, try it with a bunch of panel controls. They have nearly all the same properties such as 'Image', 'Backcolor', 'Location' etc. so it shouldn't be a huge issue.

If you are creating those pictureboxes programatically you just make a new panel instead of new picturebox

            PictureBox pbPlayer = new PictureBox();
            // becomes
            Panel pbPlayer = new Panel();
 

If you built them at design time, you can go into the Form1.Designer.cs file and change their type.

        #region Windows Form Designer generated code
 
        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.button1 = new System.Windows.Forms.Button();
            this.button2 = new System.Windows.Forms.Button();
            this.pictureBox1 = new System.Windows.Forms.PictureBox();
            ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();
            this.SuspendLayout();
 
            // 
            // button1
            // 
            this.button1.Location = new System.Drawing.Point(26, 13);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(75, 23);
            this.button1.TabIndex = 1;
            this.button1.Text = "button1";
            this.button1.UseVisualStyleBackColor = true;
            this.button1.Click += new System.EventHandler(this.button1_Click);
            // 
            // button2
            // 
            this.button2.Location = new System.Drawing.Point(207, 12);
            this.button2.Name = "button2";
            this.button2.Size = new System.Drawing.Size(75, 23);
            this.button2.TabIndex = 2;
            this.button2.Text = "button2";
            this.button2.UseVisualStyleBackColor = true;
            this.button2.Click += new System.EventHandler(this.button2_Click);
            // 
            // pictureBox1
            // 
            this.pictureBox1.Location = new System.Drawing.Point(3, 3);
            this.pictureBox1.Name = "pictureBox1";
            this.pictureBox1.Size = new System.Drawing.Size(100, 50);
            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(544, 497);
            this.Controls.Add(this.button2);
            this.Controls.Add(this.button1);
            this.Name = "Form1";
            this.Text = "Form1";
            ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).EndInit();
            this.ResumeLayout(false);
 
        }
 
        #endregion
 
        private System.Windows.Forms.Button button1;
        private System.Windows.Forms.Button button2;
        private System.Windows.Forms.PictureBox pictureBox1;
 
    }
 

This way you don't have to delete controls and make new ones, then attach event handles and so on - you just change the type of the existing control.

I'll rewrite now picturebox code. It's good thing that I have all the controls dynamic.

No, panel doesn't work... The same problem.
