I need to display various shapes in a picture box, and am trying to do so via a combobox that the user can select from. My problem is clearing a previous selection when a new selection is made.
Code to date is:
Public Class frmGraphics1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Populate cboShape with shapes
cboShape.Items.Add("Select a shape")
[Code] .....
I can't seem to find the shape tool in the toolbox? When I used VB6 there was one, so why isn't there one now? I just want to set up rows of circles so I can change the color from inside instead of using images and saying
Code:
YellowCircle.Visible = False
BlueCircle.Visible = True
Instead of doing that I want to do
Code:
Circle.BackColor = Blue
How do I draw a shape in VB.NET? Not during the program, before.
I have inserted a form into my project that a friend sent over. The form works but if I add more controls to it they are not displaying.
The controls are all there in the <form>.designer.vb file but are simply not displaying when I run the form.
I have looked around the net but can find no reference to a similiar problem.
I'm looking for a tool that will allow me to display, and change forms, inside my original form.
View 5 RepliesI'm having a small problem concerning displaying maximized child-forms in a MDI-application. Everything works fine on Win. Vista but when I start the program on a PC with Win. XP it doesn't look very nice. I found some similar threads on the internet but no answers. Does anyone know how to display maximized windows in MDI properly?

View 7 RepliesI'm working on an ultrasonic sonar and I would like to use the computer to display a standard green radar system detecting the objects. I'm using a micro controller with the software written in C to send out the sensor's angle and position and it works fine.On the computer side, I'm using Visual Basic 2010 to read the COM port which then contains the sensor's data in numbers (sensor's angle and distance between sensor and object)which is a constant stream. On the debug screen (Textbox) I can already see all the data coming through.Now my question is: How do I convert those numbers into graphics?
More explanations about these numbers I want to convert:I have a step motor to rotate the ultrasonic sensor, and it works that way:The motor advances 1 step forward, then measure distance between sensor and object, then send these 2 values out.So, if you see the attached file, those numbers on the text box mean:
000032 -> 000: step number & 032: 32cm between sensor and object
001031 -> 001: step number & 031: 31cm between sensor and object
002032 -> 002: step number & 032: 32cm between sensor and object
003007 -> 003: step number & 007: 7cm between sensor and object
and so on...
So those are the numbers I wish to convert into graphics. The scan line would need to rotate clockwise at same speed of the step motor. And then I would like to display dots when an object is detected
I am starting to develop a card game client for a CCG a friend of mine and I are creating.
I have 2 forms Client.vb and Hand.vb linked with a module.vb
In essence when the app starts up I see the client. I can then click the "Hand" button and the Hand Window is shown as well.
What my goal is is to have it so that when i hover over the card (picturebox) in my hand form that it displays a larger image of that card in the preview box (Another picture box) In Client.vb
I have everything working except when i actually mouse over the image in the hand form it creates an error:
Error:A first chance exception of type 'System.NullReferenceException' occurred in CCG 2.0.exe
The code in the mouse hover event:
Code:
F1.PictureBox2.Image = F2.PictureBox1.Image
Im Almost certain im going about this the wrong way but I cant seem to figure out any other way...

I have a program where I use a picture box (pAudiogram) to display a template. Then I use Graphics (myLine) to plot things on this picture box. Some example code is below:
Dim myBluePen As New Pen(Color.Blue) : myBluePen.Width = 2
Dim myRedPen As New Pen(Color.Red) : myRedPen.Width = 2
Dim myLine As Graphics = pAudiogram.CreateGraphics

My problem is that the gradient doesn't appear in the picture box when the form loads, paints, or when the picture box is painted. I can only make the gradient appear if i click the picture box after the form appears.
Dim xFormTopColour As Color = Color.Black
Dim xFormBottomColour As Color = Color.DarkOrchid
Private Sub frmTestGradientBars3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 10 RepliesI've problem with clearing all the drawings I've created in my PictureBox. In fact I've created animation which stops after certain time and remains on the screen. The animation is created/painted with collection of about 25 TextBoxes - input of a user.

The problem is when I add new info in 25 TextBoxes nothing appears in PictureBox and I can't start an animation. Wondering why...

I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.

I've been searching for days. I can't find anything that I think is going to work. I've probably read the answer and skipped it because I don't get it. I'm new. I've researched multithreading, sub routines and webbrowser. The webbrowser thing doesn't seem professional to me.
All I want is the animation to be smooth when it's displayed and to have it integrated into the app so it's not called from the local drive.The animated gif is in PictureBox3. Please point me in the right direction. I really don't want to use a static image.
