[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.

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.

    • Par for the course. I asked a question a few days ago and was threatened to be reported. 😂
    • Ummmm Are you kidding? Do think these books being sold are disclosing they are AI written?
    • i'm just commenting because of this madness. you simply asked "what crowd" which i too am genuinely curious about, only to receive a response in the form of a link that directs to an analysis of the audited financial statements with the accompanying notes. then you say that the guy who wrote it is stupid, which whatever, that's not an argument being discussed atm, only to receive a response from Arceles saying "i don't deal with people whose first response is an ad homenim". jesus. this is like making a claim, and then saying "i don't deal with people who speak in a certain way or swear so i'm not gonna answer you hah!" (said in a nasaly voice, not trying to depict you Arceles). then focus on the argument instead of the explanation begins... "so what don't you like about the guy (lunduke)" followed by "he just likes to insult people" and the explanation for the "crowd" being referred to was never even established. so a request for an explanation about the crowd turned into an argument about "why do you think lunduke is an idiot". wowza.
    • Sony lays off 30% of staff from Days Gone developer Bend Studio by Pulasthi Ariyasinghe Another wave of layoffs has hit the game developer space, and this time, it's a first-party Sony studio that's been affected. Following a report by Bloomberg's Jason Schreier, Bend Studio has confirmed that it is letting go of "incredibly talented teammates" as it begins work on a new game project. "Today, we said goodbye to some incredibly talented teammates as we transition to our next project," said Bend Studio in a social media post today. "We're deeply thankful for their contributions as they've shaped who we are, and their impact will always be part of our story." Bend Studio is most well-known for its 2019-released open-world zombie adventure Days Gone, which even received a remaster just a few months ago. Prior to that, the studio had been responsible for the classic Syphon Filter series while also developing several PlayStation Portable and Vita games like Resistance: Retribution and Uncharted: Golden Abyss, respectively. "This is a difficult moment for our team, but we hold immense respect for everyone who got us here," the company added. "As we move forward, we remain committed to building the future of Bend Studio with creativity, passion, and innovation in the titles we craft." While Sony did not detail just how many staff have been affected by this latest decision, Jason Schreier revealed that 30% of the studio is being laid off. This amounts to around 40 people, according to the reporter. Earlier this year, Sony canceled two live service games that were in development at Bend Studio and Bluepoint Games. It was never revealed what this mystery game was supposed to be. "Bend and Bluepoint are highly accomplished teams who are valued members of the PlayStation Studios family," Sony said at the time. It's unclear if Bluepoint, which had been developing a God of War live service experience, will soon be hit by its own wave of layoffs too.
