Showing All Thumbnails At Once With FolderBrowseDialog
Sep 3, 2011
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"

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'm working at a new explorer with checkboxes in VB 2005. It's about to be finished.i have pb to get thumbnails in my listview. Usually, com interface used to get thumbnails is IShellItemImageFactory. I had no pb with this one. But i would use IThumbnailCache because i can hold an ID on thumbnails to register them in a ImageList. I wrote IThumbnailCache as follows:

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?

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 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....

What is the best way of quickly loading a datagridview with thumbnails of images and filenames/paths found within a particular folder using a backgroundworker without affecting UI performance ?
While loading, I'd like to continuously filter the dgv's image column through a textbox to display results as the user is typing.

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.

I have a program with which I can open a second form on a beamer, this works perfect, but what I do notice it that on the taskbar (I have windows 7) I see the main icon of the app but also the form that is created.What I would like is that the second icon is not displayed on the taskbar thumbnails, this way I can't close the second form by the X but only by a button on the main app.

It's been a while since I've had to add a CheckBoxCol to a DataGridView, so I copied and pasted the code directly from the example shown in the MSDN library page here: [url]Anyway -- the column is added as expected however, there is no checkbox! (see the column "Accept" in the image I've posted). I was hoping I am missing something easy/obvious, and I've had success with this before in other apps so this is becoming frustrating.DGV's Datasource is set to a datatable found in a Dataset. Everything loads just fine. No errors.
