[VB .Net] Label Transparency over Pic


Question

I am working on my on going project and have come across a problem. I wan tto have a picture box filling the back ground with 2 labels over it. However, when I set the label background color to Web/Transparent, the background still comes out grey when I run the program and this is a problem. How do I make it so that the label is truely transparent and you see the contents of the picture box behind it?

Hmmm... i had the exact same problem with .NET... This is why i still use VB6 for most of my work, rather than using VB .NET which causes me a lot of headaches with the new structure... Some changes in .NET are really stupid, and create big incompatabilities... I believe the problem with the label (IF it is a problem) makes my life difficult so when i HAVE to do it, i use VB6... I would also be interested in a solution about this issue... Anyone knows?

Ok now here is now it works!

Conclusion: Use Form1.BackgroundImage or Panel1.BackgroundImage instead of PictureBox1.Image or PictureBox1.BackgroundImage

And when you set Label1.Backcolor to Transparece, the background of Label1 actually goes to the background or back colour of the form. I suggest you to set the image into Form1.BackgroundImage and it will work! (Or you can try use Panel, too)

When a label's background colour is set to Transparent, it inherits the background colour of its parent control. IIRC, a PictureBox cannot be the parent of another control, so you'll never be able to get the PictureBox's image to show through. You need to do as no name said and put the background image on a panel or other control that can be a parent.

Well, try this...

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 ? ? ? ?Label1.BackColor = System.Drawing.Color.Transparent
End Sub

And here's the screen shot...

Why not just override the panel's onpaint and write your own code to size the bitmap? Better yet, since panel doesn't allow double-buffering, create a user control that inherits from panel and use SetStyle to setup double-buffering.

public class UserPanel : System.Windows.Forms.Panel
	{
  /// <summary> 
  /// Required designer variable.
  /// </summary>
  private System.ComponentModel.Container components = null;

  public UserPanel()
  {
 	 // This call is required by the Windows.Forms Form Designer.
 	 InitializeComponent();

 	 // TODO: Add any initialization after the InitializeComponent call
 	 SetStyle(ControlStyles.AllPaintingInWmPaint | 
        ControlStyles.UserPaint |
        ControlStyles.DoubleBuffer, true );
  }

As far as the label not drawing transparent, what is its FlatStyle property set to? I think that some of the settings will not draw transparent( e.g. System ). Set it to Standard and it should draw transparent. If that doesn't work, again, you could override OnPaint and used the DrawString method to write text over the image. It isn't that much work to do so.

The pics have a panel that resizes the image, and a string drawn over it with DrawString. Ugly, I know, but you could probably do something nice with it.

So what if it's c# and not vb.net? you can do the same thing. The framework is the same. You can override painting in VB, you can create controls in VB.

I'll try and write this in VB.net just to show you how to do it. Granted, I don't write alot in VB so this may take a while.

    • They always have. This just updates what's included out of the box during the initial install.
    • So basically their prebuilding it into the ISOs?
    • Microsoft shares Defender anti-virus update for new Windows 11/10 ISOs by Sayan Sen Following the one for Lumma last month, Microsoft has also published a new Defender update for Windows 11/10/Server installation images this month. This update package is necessary as a Windows installation image may contain old, outdated anti-malware definitions and software binaries. Aside from better security, these updates can also provide improved performance benefits in some cases. When a new Windows installation is set up, there may be a temporary security risk due to outdated Microsoft Defender protection in the OS installation images. This happens because the antimalware software included in these images might not be up to date. Thus Microsoft says that these updated definitions essentially help close this protection gap. Microsoft delivered the latest security definitions for Windows images via security intelligence update version 1.431.54.0. The Defender package version is also the same. It applies to Windows 11, Windows 10 (Enterprise, Pro, and Home editions), Windows Server 2022, Windows Server 2019, and Windows Server 2016. Microsoft writes: From Microsoft's security bulletin, we learn that the security intelligence update version 1.431.54.0 was released this past week adds threat detections for various backdoor exploits, trojans, among others. For those wondering, the latest intelligence update is version 1.431.155.0 at the time of writing.
