Animated Thumbnails - Creating GIF From Images
Sep 16, 2010
I have a media gallery type project I'm working on, but I want to enhance it by creating animated thumbnails to "preview" the media. I have already created code to extract 10 incremented images from a pretty much any video format. Now that I have my images, I thought the most efficient way to animate them would be through a GIF. Once you have imported media to a library it will automatically generate the images, and hopefully create the gif thumbnail I'm looking for. How to generate animated GIFs in vb2010?

I am using some code that searches a variable path (usually the entire drive) for images, it then displays the entire path in a listbox. I am able to use a picture box in conjunction to view the pics one at a time. How to display them all in a listview as thumbnails so i can browse them all instead of one at a time using the picturebox. The code I am using returns a array of files if it makes a difference....

Is there a way that I can create images (bitmap, tiffs, whatever) from txt,docx,pdf,or rtf files?
One idea that I found was creating a Metafile from the file. However I am get GDI+ errors with the palette. how to get around that? Do you think this is the right track?
Dim
gr As Graphics = Me.picFile.CreateGraphics() 'i am really not using a picture box, but I thought if it helps, why not?

I have two bmp files:
footer.bmp: 200 x 200
product.bmp: 1000 x 1000
I want to create a new bmp file with 200 x 500: Append the footer.bmp into the bottom of the new image - position (0, 300) Resize the product.bmp to 200 x 300 and position into (0, 0)How do I do this using VB.NET?
Dim oBitmap As New Bitmap(200, 500)Dim oGraphics As Graphics oGraphics = Graphics.FromImage(oBitmap)

I have been learning VB2008 and have been working a little with the toolstrip. While this question isn't really urgent, I've been thinking down the road about images and image libraries that I would like to build and use in my programs. I am thinking I should set up my own library so that all programs I write will have the same look (at least as often as I want them to).
1) What does everyone use to create images? What programs, features, etc. are important? Eg. I have MSPaint and and old version of CorelDraw but have never really used them to high quality stuff.
2) Are people just using the images provided in VB2008 Pro?
3) What should I consider when working with images for use in Windows Forms programming? Currently I am not doing any web work.

i'm working on a project right now and I need to create a graphic library.The game I'm experimenting with is an RPG; this project is expected to contain many big graphic files to use and I would prefer not to load everything into memory at once, like I've done before with other smaller projects.So, does anyone have experience with libraries such as this one? Here's what I've came up with:
Have graphic library files and paths in an XML file Each entry in the XML file would be designated "PERMANENT" or "TEMPORARY", with perm. being that once loaded it stays in memory and won't be cleared (like menu-graphics)The library that the XML file loads into would have a CLEAR command, that clears out all non-PERMANENT graphics I have experience throwing everything into memory at startup, and with running the program running with the assumption that all necessary graphics are currently in memory.

This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?

I have 8 thumbnails on a thumbnail browser page where each thumbnail is just a rectangle from the main image, not the whole thing.
Problem is, this needs to run on some fairly old machines where it's too slow in VB.net although the old VB6 version worked fine. Any obvious ways of speeding the following code up, or do I need to go back to API or use separate thumbnail images?
Private bmp As Bitmap
Private bmp2 As Bitmap
Private gr As Graphics

I figured out how to show multiple thumbnail at once with OpenFileDialog and FlowPanelLayout but I want to do it with FolderBrowseDialog - when I select one folder to it show me thumbnails of all images in it.
I'm using this code:
Dim OpenFileDialog1 As New OpenFileDialog
OpenFileDialog1.Filter = "Images (*.BMP;*.JPG;*.GIF,*.PNG,*.TIFF)|*.BMP;*.JPG;*.GIF;*.PNG;*.TIFF| All files (*.*)|*.*"
OpenFileDialog1.Multiselect = True
OpenFileDialog1.Title = "Select Photos"

The fastest way to generate thumbnails using VB.net and multiple computers without bogging down the UI. Right now I have 3 computers and I run an instance of my thumbnail generator code on each. One computer hosts the images. The other two computers access the folder of images via the network. My code is written to compare the main folder and a thumbnail folder to see if new thumbnails need to be generated. If so, a thread is generated and the thumbnail generation code is ran on the thread. There are 5 threads created in all. So, theoretically, across 3 machines, I'm getting 5 independent threads and I'm thinking that Windows 7 automatically spreads the load across the local cores. In an effort to avoid duplicating work, the comparison is done before the generation of each thumbnail.
This method is faster than using only one computer but drags down the performance on all computers (THE UI also becomes unresponsive). I'm looking for a better way to
1.) Produce the thumbnails as fast as possible
2.) Keep all UI's responsive (boy possibly controlling the priority setting) and
3.) Done within a single instance of the program.
In the #3, I mentioned that I would like to use one instance. Is it possible for networking information be used by the hosting computer that will allow threads to run on the other 2 computers? This way, the 15 threads will be controlled by a single host computer.
Here is a snippet of my
Public Sub CreateThumbsFUNCTION(ByVal IMAGE As String, ByVal MAXDIMENSION As Integer)
'following code resizes picture to fit.
'IMAGE needs the full path
'If thumbnail already exists, it will skip

I have an app that needs to bulk rortate a folder of images either left or right using
rotate90flipnone or rotate270flipnone
The app does in fact rotate the images but when viewed as thumbnails in explorer they are not rotated. So my app needs to rotate the thumbnail as well.

I am trying to create a photo kiosk software where the user loads images, then they are displayed as thumbnails, and then the user can select a thumbnail (or multiple thumbnails) to choose sizes. (imagine a photo kiosk you would see in walmart for example)
So far I have done the following. I am able to load images. I then dynamically create a panel box for each image, and within the panel box I create a picture box and a label to display the thumbnails and the actual file name.

I have a program with three tabs. On tab one I use a folder browser dialogue and load file names into a listbox. These are usually ".tif" image files but could be other image formats. I save the folder location in a variable. On tab 2 I have a Flow Layout Panel. I need to 1) use that folder location on tab 1 as the source of files to be loaded into the flow layout panel and have it do so when I use the Folder Browser Dialogue; 2) I need to click on these tab2 images (in the Flow Layout Panel) to select them, and to trigger events. Mainly create a list of selected image thumbnails.

I want to display files pretty much as similarly to windows explorer when set to thumbnails as I can. Most importantly I need to be able to show thumbnails of videos and images that windows can(im aware that not all videos are supported).
I'm fairly new at this. I havn't done any programming in years and I've never been amazing at it, I've already got this directory list done so this is the next step in my project...

I would like to know if the .NET framework gives you a way to retrive the littles thumbnails Windows XP+ generates when you alt+tab. The application I try to make should be able to get a window capture (ALT+PrtScr) of another Window that is not necessary Active and could be partially or completly hidden behind another one. I tried the codes found there [URL] altprintscreen with no success in the case the window I'm trying to capture is not visible.

First part of a huge block will contain some text. That block is not always visible. it will be visible when the user is inputing a control. It is drawn in a bitmap image which will later be a part of the final image of the form.The second part consist of several small bitmap images most probably will contain a letter. These images will not change but there position will keep changing by time. These images will be free to move even beneath the huge block (If visible).I used a timer with 1 sec. interval to redraw form, but when the block is visible it keeps flickering because the timer clear the form and redraw the block.
I tried to use different container for the block like the PictureBox but when the small image goes beneath the block it just disappear.The block color code is "Color.FromArgb(100, Color.Black)" I tried lower Alpha components and that didn't make any difference.My explanation is that the background of the picturebox is not transparent. If I'm right how to make the picture box transparent?
