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,

View 1 RepliesI am making an application using VB.NET 2010 and I have set a background image which flickers every time I open any new Form or hit tab for jumping from textbox to textbox By pressing (tab) it only flickers once but always flicker when ever I close the form and open again. I have tried everything; background image set to, STRETCHED, CENTRE, ZOOM but still it's the same.
View 1 RepliesAfter scouring the articles online I have come up with this design for a winforms based touchscreen app that needs smartphone like scrolling. The app itself will run on a tablet laptop or touchscreen desktop.I put everything I want to scroll on a panel. Set autoscroll to true (which will show scrollbars)Now put this whole panel inside a groupbox.Shrink the groupbox until the scrollbars are hidden (visually hidden, not visible = false)
Now the fun part I am stuck at.I think I have to handle the mousedown, mouseup & mousemove on the panel to set the autoscrollposition so that when someone touches the panel and drags, it does it's scroll magic. Please help fill in the few lines of code in below method stubs. The msdn doc on autoscrollposition is very confusing since it returns negative numbers but needs to be set to positive with abs and what not.

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.

View 2 RepliesHow do I reduce flicker in a vb2005 panel?Inside the parent panel I have 2 other panels that I'm am using.
The outer most panel contains a background sprite and the two innermost panels are overlays that change to fit the places in the background sprite.When I change the overlay sprites I would like to reduce the flicker and make it a smooth transition from one sprite to the next.
Here is the code that changes the images in the overlay panels the overlay panel is not changed if the new value is the same as the old value

I have a htpc project that I am working on. The main program loads dlls which are basically other win forms. On each of these forms, including the main program, I use a picturebox (double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I go from the main program to the dll, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker?

I have a panel on my main form that has vertical scrollbars enabled. I also have a custom control I have built that is the same width as the panel and has a height of 45. I store multiple of my user controls in an array, and I want the panel to display these controls like a listbox... one stacked on top of the other. So I loop through the array and add each control to the panel at coordinates right under the previous one.This works fine, and as long as I use the the mouse to scroll down and expose the controls I'm interested in and then clicking on that control, things work great. The problem comes in when I want to use the arrow key to move down to the next control. If the next control is visible on the panel, it works fine.

i am currently trying to improve my skills regarding simple graphics. currently i have a form with a background image. on top of that there is a movable image drawn during Form_Repaint. the image is a character that is animated. you click and the character moves to the new point. that all works great atm. i am even able to add new "AI Chars". they just randomly walk through the form and every time they stop, there is a 10% chance every 15s that they move somewhere else (random point). as is said, that works great. but now i am kinda stuck. since my "engine" (lets say so) is in isometric perspective, i need the ability to scroll.
View 4 RepliesWhat would be the best and easiest way to change background image in a VB application from images that are preselected by user from any given folder on the hard disk.
So say "Mike" selects some images in D:ImagesNature in the Nature folder we have lets say "20" images. Now the VB app reads this and saves path so next time its open its fetching images from that folder once more. And every few sec lets say 45 sec a new image is loaded for background.
I have set a scrollable control's autoscroll to true. What do you do when you don't want a scroll to occur? For example, suppose you have a RichTextBox and a button side by side as below:
Notice that "button1" has the focus. If you click on the RichTextBox to give it focus, the scroll bars will scroll until the upper left corner of the RichTextBox is in view.
But what if, for whatever reason, you wanted to keep button1 in view? How would you do that?
Background of form: black
background of char, bombs and shrooms: transparent

"Automatic Image-scroller". The scenario is quite simple. I've got one single picture, and it should move up and when it moves out of frame, the same picture would appear beneath itself and continue to move up. Kind of a loop.The problem is that i haven't got a single clue how to make it in code-behind nor XAML, but it has to written in "code-behind" cause of the things i'm hooking it up with.

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?
View 3 Replieswhat I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:

I have a panel with the BackgroundImage set that I'm using as a button. The panel also contains a PictureBox with a png image loaded so that parts of the image are transparent and the panel image shows through. On MouseDown I change the panels BackgroundImage, then on MouseUp I change it back again. The problem is that when the panel image changes, the PictureBox flickers badly when redrawing its transparent areas. I've tried using the DoubleBuffered property of the form its on; no luck there. I've also tried SuspendLayout just before changing the image, refreshing the PictureBox, then ResumeLayout. Still no luck.
