c# Add transparent label on web eye web cam control

I have been working on an Iron Man hud. I am using WebEye to access the web cam... now i have to add label over the web cam control but the label is not transparent
I have tried every control but cant use the transparency function..
Here's my code
foreach (WebCameraId camera in webCameraControl1.GetVideoCaptureDevices())
{
comboBox1.Items.Add(new ComboBoxItem(camera));
}
if (comboBox1.Items.Count > 0)
{
comboBox1.SelectedItem = comboBox1.Items[0];
}
ComboBoxItem i = (ComboBoxItem)comboBox1.SelectedItem;
try
{
webCameraControl1.StartCapture(i.Id);
}
finally
{
//Do something if u want to
}
please help!!

Actually, creating a transparent label will not help over video. If your webCameraControl is not a sealed class, you can inherit it to add the text directly on it's surface, like I did with this picture box:
public partial class LabledPictureBox : PictureBox
{
public LabledPictureBox()
{
InitializeComponent();
}
#region properties
// I needed to override these properties to make them Browsable....
[Browsable(true)]
public override string Text
{
get
{
return base.Text;
}
set
{
base.Text = value;
}
}
[Browsable(true)]
public override Font Font
{
get
{
return base.Font;
}
set
{
base.Font = value;
}
}
[Browsable(true)]
public override Color ForeColor
{
get
{
return base.ForeColor;
}
set
{
base.ForeColor = value;
}
}
#endregion properties
protected override void OnPaint(PaintEventArgs pe)
{
base.OnPaint(pe);
// This is actually the only code line that's needed to add the text to the picture box
TextRenderer.DrawText(pe.Graphics, this.Text, this.Font, pe.ClipRectangle, this.ForeColor);
}
}
The most important thing here is the line right after base.OnPaint - That line actually paints the text directly over the surface of the already painted control.

Remove the ToolStripMenuItem left border

I have my ToolStripMenuItem and when I run the application, it looks like this:
As you can see, there is a little white space at the ToolStripMenuItem left.
How can I remove it? I tried to edit every property but it still remains...
Thank you all in advance!

To change appearance of menu item you should use a ToolStripProfessionalRenderer using a custom ProfessionalColorTable.
To change that color, you should override ImageMarginGradientBegin property of custom color table and return the color you want.
For example you can have :
public class CustomColorTable : ProfessionalColorTable
{
public override Color ImageMarginGradientBegin
{
get { return Color.Red; }
}
public override Color ImageMarginGradientMiddle
{
get { return Color.Green; }
}
public override Color ImageMarginGradientEnd
{
get { return Color.Blue; }
}
public override Color ToolStripDropDownBackground
{
get { return Color.Yellow; }
}
public override Color MenuItemSelected
{
get { return Color.Pink; }
}
//You should also override other properties if you need.
//This is just a sample code to show you the solution
}
And then in your form load:
private void Form_Load(object sender, EventArgs e)
{
ToolStripManager.Renderer = new ToolStripProfessionalRenderer(new CustomColorTable());
}

Setting default size/text of custom control in c#

I am creating a custom control in my C# application in order to add a new property (MyProperty below). It is inheriting from Label. One thing I would like it to do, is display at a particular size when I drag it on to my form (200x132). I'd also like it to display no text. However, no matter how I try to do this, it doesn't seem to work. I am able to set BackColor and BorderStyle with no problem, however. I'm fairly new to C#, so maybe I'm missing something obvious.
Here is my code:
using System.Drawing;
using System.Windows.Forms;
namespace MyProgram
{
public enum MyEnum
{
Value1, Value2, Value3
}
public partial class MyControl : Label
{
public MyControl()
{
BackColor = Color.LightCoral;
BorderStyle = BorderStyle.FixedSingle;
AutoSize = false;
Size = new Size(200, 132);
Text = "";
InitializeComponent();
}
protected override void OnPaint(PaintEventArgs pe)
{
base.OnPaint(pe);
}
private MyEnum myProperty;
public MyEnum MyProperty
{
get { return myProperty; }
set { myPropery = value; }
}
}
}

The answer provided via Dispersia's link has a bug, in my opinion. The text reset should happen once and then whatever a user does after that shouldn't matter. In Dispersia's link you can't actually set the text back to the control name because it will keep blanking it out.
The answer provided by cramopy doesn't technically answer your question, it is a way to do it by using the defaults on a UserControl though. You'll also need to bind the Text property of the UserControl to the label's.
The following should work while inheriting from a Label and will only reset the Text property once.
public partial class MyControl : Label
{
#region fields
private IComponentChangeService _changeService;
private bool canResetText = false;
#endregion
#region properties
protected override Size DefaultSize
{
get { return new Size(200, 132); }
}
[Browsable(false)]
public override bool AutoSize
{
get { return false; }
set { base.AutoSize = false; }
}
public override ISite Site
{
get { return base.Site; }
set
{
base.Site = value;
if (!base.DesignMode)
return;
this._changeService = (IComponentChangeService)base.GetService(typeof(IComponentChangeService));
if (this._changeService != null)
this._changeService.ComponentChanged += new ComponentChangedEventHandler(this.OnComponentChanged);
}
}
#endregion
#region constructors
public MyControl()
{
base.BackColor = Color.LightCoral;
base.BorderStyle = BorderStyle.FixedSingle;
}
#endregion
#region methods
protected override void InitLayout()
{
base.InitLayout();
this.canResetText = true;
}
private void OnComponentChanged(object sender, ComponentChangedEventArgs ce)
{
if (ce.Component != null &&
ce.Component == this &&
ce.Member.Name == "Text" &&
base.DesignMode &&
this.canResetText)
{
((MyControl)ce.Component).Text = string.Empty;
this.canResetText = false;
if (this._changeService != null)
this._changeService.ComponentChanged -= new ComponentChangedEventHandler(this.OnComponentChanged);
}
}
#endregion
}

#Dispersia reply only answers the myControl1 thing. (deleted meanwhile)
Here comes a full guide for solving your problem:
Add a new UserControl named MyLabel
Change the following within Designer Mode:
BorderStyle:= FixedSingle
Size:= 200; 132
Now Drag&Drop a new Label onto the control
Edit those Label values (also within Designer Mode):
AutoSize:= false
BackColor:= LightCoral
Dock:= Fill
Text:= clear/empty this box!! (don't write this inside the box, you really have to clear it!)
TextAlign:= MiddleCenter
Just recompile your project && add a MyLabel control from the Toolbar.
Now it show up as you wanted!!

How to change the appearance of a MenuStrip [duplicate]

This question already has answers here:
How to change menu hover color
(4 answers)
Closed 9 years ago.
I add a MenuStrip in my app and is add on ManagerRenderMode at Render Mode. The problem is with the appearance, look offal. Look at those two photos, I want to change that white border of submenus in transparent, that blue rectangule that look offal on gray for the menu and for the submenu in dark gray (and his border that is a dark blue) and the border white of menu when is selected. How I can do this ?
BackColor is: 36; 36; 36 and ForeColor is LightGray.
I managed to change the blue rectangle, the white rectangle when the option is selected, the blue rectangle when I select an option of submenus, but I don't know how to change the white border, please help..
Here is the code so far...
Color culoare = Color.FromArgb(20, 20, 20);
Color culoare1 = Color.FromArgb(36, 36, 36);
public override Color MenuItemSelected
{
get { return culoare; }
}
public override Color MenuItemBorder
{
get { return culoare; }
}
public override Color MenuItemSelectedGradientBegin
{
get { return culoare; }
}
public override Color MenuItemSelectedGradientEnd
{
get { return culoare; }
}
public override Color MenuItemPressedGradientBegin
{
get { return culoare; }
}
public override Color MenuItemPressedGradientEnd
{
get { return culoare; }
}
public override Color MenuBorder
{
get { return culoare; }
}

You can do this by creating your own ColorTable, and overriding the properties you wish to change the colour of:
public class TestColorTable : ProfessionalColorTable
{
public override Color MenuItemSelected
{
get { return Color.Red; }
}
public override Color MenuBorder //added for changing the menu border
{
get { return Color.Green; }
}
}
You would use it like this:
private void Form1_Load(object sender, EventArgs e)
{
menuStrip1.Renderer = new ToolStripProfessionalRenderer(new TestColorTable());
}

Your approach is incorrect. You do not style menus and toolstrips using forecolor/backcolor.
Take a look at ToolStripProfessionalRenderer
Example on how to use this
public class MyToolStripRenderer : ToolStripProfessionalRenderer
{
/* override styling/drawing here */
}
MenuStrip strip = new MenuStrip();
strip.Renderer = new MyToolStripRenderer();
//this will set RenderMode to "Custom"
consider using this example on CodeProject as some research.
Better still, VBForums have loads of them, already implemented (in the usual Luna, Office, Windows, Visual Studio styles!)

WinForms Custom Control Colors

I am trying to customize the controls on my WinForms database application.
So far I have only tried to customize labels and buttons using the following code:
namespace MyNamespace
{
public class CMSLabel : Label
{
private Color cmsLabelBackColor = aSystem.LabelBackColor;
public CMSLabel()
{
this.BackColor = cmsLabelBackColor;
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public new Color BackColor
{
get { return cmsLabelBackColor; }
set { }
}
}
public class CMSButton : Button
{
private Color cmsButtonColor = aSystem.ButtonColor;
public CMSButton()
{
base.BackColor = cmsButtonColor;
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public new Color BackColor
{
get { return cmsButtonColor; }
set { }
}
}
}
The Button control works perfectly, but the Label controls exhibit no BackColor at all, yet I've used the same code for each control type. Can anyone spot what I have done wrong?

You have to change the "base" color:
public CMSLabel()
{
base.BackColor = cmsLabelBackColor;
}

In the CMSButton you set base.BackColor, but in CMSLabel you set this.BackColor, which has no code in the setter.
