I am manipulating oval objects in a panel on a form, i.e. size, color, location, etc., using trackbars. After each change, I want to put all pixels in the panel into an array for sending to a slave display. Is there an easy, straightforward way to do this other than getpixel?

View 2 RepliesI have a forms app that contains a panel. This panel contains an picturebox - the user can then drag the picturebox image.
I need to add an image? in the panel that will not move when the user drags the picturebox image.
This image? needs to be transparent so that the picturebox image can be seen though it when drag occurs.
I've tried drawing directly on to the panel but nothing appears. Perhaps what I am drawing is behind the picturebox?
I've got a panel in windows forms (Visual Studio 2008) which has a background image (A book shelf).When scrolling the image flickers and does not redraw so looks awfully - I've tried creating a new object to use double buffering but this has no effect,

i have developed a windows application whose interface has multiple picture boxes panels with background images for rich look and also a usercontrol which contains a gridview and WPF scrollbar in an element host. All these controls are placed in one panel (this is also having a background image) which is equal to the size of windows form. The reason for placing all these controls in the panel is that the window can be resized, if needed, allowing scrollbars.
Due to these large number of controls in which some of them have transparent backgrounds loaded in a large panel having background image, the window is flickering when moved or any other application's window is moved over it.
I have a picturebox inside a panel with scroll bars.
I can zoom in or out the image in the picturebox by changing the PictureBox.Size, and the scrollbars update automatically.
How do I convert coordinates in pixel returned by the PictureBox.MouseMove event into image coordinates when the scrollbars value is not zero and the PictureBox.Size is not the original?
I'm developing an application in VB.Net (VS2008) which allows the creation of classroom layouts. The layout is a panel and has child panels (seat objects) the seats are then populated using drag and drop and show a preview of the person sitting there.
I would like to export this panel to a printable format such as jpeg, pdf etc.I have tried using the CopyFromScreen but I can't get this to only output the layout panel. (some of the panel could be off the screen at the time of export)I have also considered using HTML outputting each seat as an absolutely positioned div container. Then printing the HTML page.

I have quite an annoying problem and I don't know how to fix it. See I have several panels in one of my forms, all with background images. On the start of the application, the form slides down, and when the form reaches a set value, all my panels slide out.The problem is, when the panels are sliding, they flicker furiously! It's really annoying and I'm not sure how to fix the problem. When the panel reaches it's set value and stops moving, the flickering stops. I can only assume it's because of the background image
View 4 Repliesediting a picturebox...i have a class called panelArray and it builds an array of panels based on the number of panels i pass it...each panel has 4 labels and a picturebox added to it when the panel is created. I'm able to edit the labels by using something like:
Me.HostForm.Controls.Item(replaceIndex).Controls.Item(2).Text = ""
Since there are 5 objects total (1 picturebox & 4 labels) i thought i would be able to just use the same strategy for the picturebox, but it doesn't like using Image in the same manner it uses .Text?

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).
I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.
