Arisen With The Picturebox Control?
Oct 5, 2010
A problem has arisen with the picturebox control since I have upgraded to VB2010 Express. I cannot be sure that it happended at the upgrade or soon after as something else changed since.
I have a database application that contains books and CDs and part of the display of each item is the cover from a directory c:datacovers and I use the code below to load the files in turn. I started developing the programme un VB2005, thence to VB2008 and the picturebox never flickered but does now with each reload of an image what seems to be three times.

I need to plot some analog values read from the serial port.I plot them in a picturebox starting from left. When I reach the end of the control at the right side I shift all values to the left of a point and I plot the new point at the right, (I have some flickering but it could be acceptable). This is my plotting control.My problem is that I have to clear the control (picturebox) in order to plot the shifted graph, but the method Clear of the Graphics class clears everything inside the picturebox, even my grid.How can i make always visible a grid "in" my picturebox?
1.a transparent image with a grid over the PB? (the clear method cannot remove it)
2.an image with a grid below the picturebox that must be with a transparent background to make visible the grid?
3.multiple layers on the same picturebox?

I've got a Panel on a main Form containing a PictureBox control on Top of a TableLayout control. Both the child controls have their docking properties set to Top. The Picture control has sizemode set to Zoom.
What I'm finding is that the picture doesn't size properly when I start the app. There is a border at the top and bottom in the PictureBox control. It's only when I resize the overall form that it's correct.
So at the moment I've got this ugly bit of startup code, just to fix the problem Me.WindowState = FormWindowState.Normal Me.WindowState = FormWindowState.Maximized
What am I missing?

This form has a picturebox and a button. The program draws a random line onto the picturebox every time the button is pressed. I want to modify the program so that it also draws a line onto the picturebox when the program is first run. I added a draw() to the form_load event but that didn't work. What do I need to do?
Public Class Form1
Dim x1 As Integer
Dim y1 As Integer

Can you control what part of the image is shown in the picturebox. ex. you only want the top left 100x100 pix shown of a 1000x1000 pix image?

I'm writing a small program in VB.NET (2008) and would like to know the following..I am loading a metafile in to picture box. My problem is that the metafiles I am using have a considerable amount of "Empty Space" around the actual object I want to display.Is there a way to move the metafile in the picture box, maybe set the images' position in the picture box or best, clip the metafile so that only the drawing part of it is displayed.
Also is there a way to have more than one metafile displayed in the picture box at the same time, say side by side?

Following on from my question here [URL]
If I replace an image in a picture box, should I dispose the original image first?
Or, what about this situation:
Dim bm As New Bitmap(32,32)
bm = New Bitmap(32,32)
bm = New Bitmap(32,32)
bm = New Bitmap(32,32)
Does bm need only to be disposed at the end, or should it be disposed before each re-creation?
A big oversight there on my part. I knew a control took care of disposing its children but It hadn't occurred to me that I should dispose an old image if I replaced it.

I'm creating an app for school to mark targets that we shoot in shooting competitions. Now I have created a dll in C# to do the marking bit and it works.Now the problem I am facing is that my app gets a image from the scanner (A4 size @ 600 dpi) and putting it in a picture box.There will always be 20 targets to be marked per image( However I want this to be able to vary to provide flexibility) My dll accepts a image that contains a single target so I need 20 individual images of targets.Create Drag able Rectangles in the picture box and crop the images from there . There are 2 ways of accomplishing this.
#1 Create a Control and set it's parent to the picturebox. (This should provide a location relative to the picturebox Right ?)
#2 Use only GDI (eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeew)
so my choice would be to create a control except I have never created any control from scratch and I have no idea how to do the visual drawing part of a control.

Sometimes, I have a picturebox lets say 100x100. But the image it will display is actually 100x400. I don't want to increase the size of the picturebox itself. Instead, I would like to create a vertical scrollbar (or horizontal if needed). I could not find a scrollbar in the toolbox, so I guess I have to code it. But, how? And I still wonder if I didn't make a mistake and didn't see the scrollbar in the toolbox.

i know this is probally a really simple question but i have looked through my book and all my notes and googeled and couldn't find a answer that suites my needs.baisicly i have a combobox that gets loaded on form_load, what i want to do is load the appropriate picture into a picturebox when someone selects a item from the combobox. what i cant figure out is how to get the picture into the combobox using code. all the images are saved in my debug folder for the program. picturebox.image = picture.png this is what i asumed it would be but have tried with parenthises, quotes and both and it dosent work.

I have a picturebox (pbRows) that I want to always be aligned with the right side of the screen. The form may be wider than this (I have a horizontal scrollbar), but the picturebox always needs to be along the right edge of the screen. Currently I have this code snippet in the form_load subroutine:
Dim rowsX As New Integer rowsX = Screen.PrimaryScreen.Bounds.Width - pbRows.Width pbRows.Location = New Point(rowsX, 25) However, the picturebox is aligned with the right edge of the form (initially hidden off the screen). Am I missing something obvious?

I just started with Visual Studio 08 Professional. After compiling my project, my virus scanner gives me the message that the virus TR/Dropper.Gen is in my project. I tracked it down to the picturebox control. If I delete this control, everything looks fine.However in an new project, which only consists out of a form and a picture box with a jpg image I get the same message (This project doesn't have any code). The picture doesn't matter. Even with the standard wall papers, I get the same message.

How to add a control like picturebox programatically and Allow user to move it with mouse? on google but cant find anything. Thats why I am here. In my application user creates a picturebox and a label at runtime by selecting a file from drag drop. User can create as many files he wants. But the problem is that I dont know that how to move both picturebox and label to change their location in a flowlayoutpanel which contains these controls with mouse. I know that how to add a control like picturebox programatically but dont know how to move it. I add picturebox by:

If you are using VB.Net 2005 or earlier. It was asked if a control can be made star shaped in this thread. [URL]. Then I have updated my Shape extension method to include a optional third parameter. The 3d parameter is indent percentage or indentPercent. The default is zero so there is no indent. If you indent by say 50% you will get a star shape.
The various ways you can call this extension method are;
'Please note: myControl may be any kind of control
'such as a Button, a PictureBox or whatever.>>
Dim myControl As Control = New PictureBox()
'Defaults to 6 sides with no rotation angle.>>
myControl.Shape()

I'm inexperienced with windows forms (vb.net), and I have a rather silly question.I'm opening an old project of someone elses, and there's a PictureBox control on the form. The PictureBox has a photo, and I'm trying to find the location of the photo on the computer but can't find it.In ASPX, I can just look at the code behind and find out where the tags are pointing to (for the photo).The only code that exists for my object, with the image property is this: [code]

I am writing a VB 2008 Express Edition application which has multiple forms. All of the forms contain one or more PictureBox controls. All PictureBox controls have assigned bitmaps via Image property during development mode. So far, all the bitmaps displayed during runtime without a slightest problem. Now, suddenly, not a single new one (i.e. which I add from this moment on) would display bitmap during runtime. All the old ones (i.e. those which I have added up to that unspecified point in time when something went wrong) still display bitmaps fine as they did before. But any newly added PictureBox (or, come to that, any other control which can display bitmap.
I have tried also Label control) displays the bitmap loaded via Image property only during development mode. During runtime the PictureBox shows as empty. I tried to load the bitmap during runtime via command Image.FromFile and that works fine (but I don't want to use this approach in my program). If I create a completely new application, all PictureBox controls display the bitmaps just fine. I don't get any errors or warnings in VB editor. I reinstalled the whole VB 2008 Express Edition including SP1 and .NET 3.5 SP1 with no difference whatsoever (as would be expected as any new application works with PictureBox controls fine).
