I can't really figure out how to extract frames and what not from an animated image stored in a picturebox. I made a post earlier similar to this matter. But now I must ask how it is that you work with GetFrame and SetActiveFrame.

I am writing an industrial control front-end that has some "fancy" graphics to indicate the states of some machinery. For example, I indicate that some heaters are on by showing red wavy arrows emanating out from a picture of a heater. I accomplished this by creating a class that inherits from PictureBox and using a timer to advance the images:
Public Class AnimatedPictureBox
Inherits PictureBox
Private WithEvents Timer As New Timers.Timer
Public Property Interval As Double
[Code] .....
My question is "Is this an alright way to go about this or is there some obvious better way?" I'm not too good at programming and am worried that having several of these objects with their embedded timers taxing the CPU. I went with animated GIFs for some other animation stuff, but here, I wanted to be able to handle image formats that can handle a larger palette than a GIF (if that makes sense). In other words, when I tried to save some of my animations as GIFs, the image quality took an unacceptable hit.

View 6 RepliesI've been racking my brain trying to figure this out. I've done a ton of searching but I can't find what I'm looking for. Right now my program gets a image file, converts the image to 4 colors (Black, Red, Yellow and Green), then converts each pixel to a number for that color.This works great, but now I'm trying to do this for an animated image, but I need to be able to loop through each frame, but I haven't been able to figure out how to access each frame of the image.

View 1 RepliesI'm looking for a way to limit Picturebox repaints. For example, I wish to be able to only call "repaint" a certain amount of times per second. All my searchs have come up with nothing. I could start a timer and get it to call repaint manually but that only ends up calling it more as it doesn't stop the normal form raising the event.
View 3 RepliesI have a picturebox with a animated gif,as yuo can see it goes up the bricks, 1,2,3,4 etc as it should when displayed in my picturebox it goes threw the bricks 1,3,5 then back round next time 2,4,6 and so on..is there some sort of delay?
View 4 RepliesI'm trying to get an animated gif picturebox to play and then after it is done "Playing" it will hide and show another picturebox. I thought I could do this with a timer but I can't really seem to get it to work. I need this in the form_load because the first picturebox shows on form load.

I wrote a little utility that compares pictures in a directory against each other and will display them side by side in two pictureboxes so the user can weed out duplicates. Anyway, seemed to be working fine until I started testing a directory that had animated gifs in it. The gifs will start playing in the form's pictureboxes, but at random (with no action taken by user) one of them will crash and give the attached error script. The other gif will continue running, but the offending picturebox will have the unrecoverable red "x", reloading or changing images does nothing after that point for that picturebox. As part of the apparent randomness, it will happen on either picturebox and the amount of time before it happens varies and does not seem to correlate to anything. For additional confusion, I have also seen where there is no error thrown, but both picturesboxes will suddenly go to the red x in the middle of a gif.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

"pbAnimated" PictureBox contains the .GIF animation. How can I save that animation to file?
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.
[Code]...
What I can do: Display an image (e.g. a bitmap) by loading it into a control (e.g. picture box), showing that picture box (visible equals true / refresh) and then hiding it (visible equals false / refresh).The onset of the image onto the screen is not necessarily synchronized with the raster scan (needs to run on CRT monitor) meaning the lower portion of the image may appear one (partial) frame before the upper portion. Though I can specify (roughly) how long the image is on the screen I cannot specify the number of frames and there is enough variability in the timing that I will not get the same number of frames every time.
What I'd like to do: I'd like to be able to have my display wait until the beginning of the next frame before showing my image. I'd also like to tell it exactly how many frames to show the image before removing it. Ideally I'd like to be able to cue up multiple images to be shown for one frame each in order (animation).
I've found a lot of information on the web about DirectX but the few tutorials I've tried are overly complicated for my needs and invariably fail to start for unspecified reasons.I don't need 3D.What I want to display would work just fine in a picture box if the timing were cleaner and predictable.

Does somebody know where i can get Microsoft's status indicator bar animated image that has a progress bar on it that when it reaches the maximum it goes the other way round.
You can find a small version of it in :c:Program FilesMicrosoft Visual Studio 8Common7VS2005ImageLibraryVS2005ImageLibraryanimationsstatus_anim.gif and it is called
"Indeterminate status indicator bar".
I was thinking is there anyway VB2005 can be done if I create an animation( car) such that its movement can me opearted using another external component(example a sensor).

View 3 Repliesdue to folder size limitation in Outlook/Exchange I must archive older mails on disk as *.msg files. So I am still able to search for <TEXT> in explorer.
I create the *.msg files by drag&drop a bunch of mails from the Outlook folder to the disk folder. Unfortunately the changed-at date displayed in explorer is the date of the file creation and not the sent-date as displayed in Outlook.
I know how to change the changed-at date using SetFileTime but I don't know how to extract the sent-date from the .msg file to use it.
My question is: how can I open (in VBA) a .msg file and extract the sent date of the mail?

View 8 RepliesI have a Picturebox and a two Buttons on my Form. On click of one of the buttons I want to change the image in the picture box at runtime.
