[VB.NET] Draw Line on Flow Control Panel


Question

Hey gang,

I'm in need of the ability to draw a box around a picture control (frame it) and my code works fine

Dim penGray As New System.Drawing.Pen(System.Drawing.Color.DarkGray)

Dim grpLine As System.Drawing.Graphics

grpLine = Me.CreateGraphics()

grpLine.DrawLine(penGray, Me.FrameX1, Me.FrameY1, Me.FrameX2, Me.FrameY1)

grpLine.DrawLine(penGray, Me.FrameX1, Me.FrameY1, Me.FrameX1, Me.FrameY2)

grpLine.DrawLine(penGray, Me.FrameX2, Me.FrameY1, Me.FrameX2, Me.FrameY2)

grpLine.DrawLine(penGray, Me.FrameX1, Me.FrameY2, Me.FrameX2, Me.FrameY2)

'The me.FrameX... are properties... not a real issue.

The problem is, I want to draw these lines not on the Form but on a Flow Control Panel.

Any ideas?

Thanks,

James

Create a Graphics object from the handle of the Flow Control Panel.

			Graphics g = Graphics.FromHwnd(flowLayoutPanel1.Handle);
			g.DrawLine(Pens.Black, 25f, 25f, 75f, 25f);

Or handle the flow control panel's Paint event. Am I missing what it is you want to do?

You got it. Thank you so VERY much. I owe you one.

    • Is there anyone who did not see Microsoft extending updates for Windows 10? There are still ALOT of people who wont switch and it will become a security nightmare when they don't get security updates.
    • You need an MSA for the other two options as well (pay 1000 rewards points or $30). To me this reeks of desperation and defeat that they're not seeing W11 being adopted as quickly as they would like.
    • Where was this article in the Windows 8 era? Microsoft was thinking almost the same back then. Just look at the response they received with such thought process...
    • Hahaha! I've been arguing with my dad for 10 years (he's pro-Tesla, I'm impartial as I don't trust a lot of the people and their tech in these robotaxis) about this whole charade. His continued argument is the cost factor (economies of scale principle) and the associated technology (different dependencies of which reduced production cost is a potential outcome thus feeding into the reduced cost argument). And my rebuttal is the broad-market trust factor -- it's often not the most innovative or first-mover that wins (Uber and Tesla have been arguing/investing in autonomous vehicles forever) but rather the option that builds the most trust amongst the commonwealth. VW and Toyota are not the first or best or cheapest cars on the road, but they've built a long of continued trust to the scales of being the largest automakers by volume worldwide. Supercar makers have the highest profit margins, Tesla has the highest stock price, but VW and Toyota have the sales volumes. As it stands, the writing is on the wall... No matter what advantages Tesla had in their ambitions, they have an even-longer road to repair public trust than any other robotaxi provider (foreign or domestic). If the trend continues, everyone will realise that their market valuation is based on their non-automotive efforts (including not robotaxis or consumer humanoids).
    • Or just use Linux and live free. For the anti-Linux brigadiers reading this, this is the part where you go: Nooo! I love being digitally abused by Microsoft 😡😡 /s
