I need to grab a thumbnail from a video file. I dont mind if i need to somehow grab it myself.... But I was doing some research and found IExtractImage which grabs the thumbnails out of the thumbs file in the directory... I haven't found any examples on how to use it in vb, only C#
how to use this or another way to get thumbnails from video files?
I would like to create thumbnails into a VB (2005 or 2010) form from video files.
I have a directory (in my hard drive) with video files (.mpg).
How to show video thumbnails for each video file?
My VB code (for images) is attached below and I want to convert it in order to manage video files.
Private Sub ThumbButton_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles ThumbButton.Click
Dim imagepath As String

Is there a way to show videofiles' thumnails in VB application? Ideal situation would be so that the application would recieve videofiles via drag and drop and then show thumbnails from them the same way as you can see a preview thumbnails in Windows file-explorer.

the problem lies with "SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE" I an example of it on the net and it works in the sample app but not in mine. It won't compile because it says "Name ShDocvw is not declared" and i've searched through the example app and can't find it "declared" anywhere. I had a look at the designer generated code and found

what is a AxSHDocVw.AxWebBrowser? Now i've done some searching and found that apparently "SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE" no longer works in 2005.
I am in search of a way to access a files thumbnail preview and push it to a picturebox on my form. I have the code below that works for jpg files, however it does not work for say a word document's thubnail. displaying the word documents thumbnail in a picturebox would be great!

Im looking to create a thumbnail from a jpg image. the image is stored in c: empimage.jpg all im trying to do is create a thumbnail from this and save it in c: emp humbimage.jpg. Ive found a number of C# tutorials and some vb.net ones. Apparently this is a really easy thing to do.
View 1 RepliesIs there anyway to save a thumbnail of an image, then save it so that, when viewed through My Computer, the thumbnail is displayed for the file. Basically, what I mean is to do something similar to the way you can see a preview of a pdf file, or Microsoft Word file, or Microsoft Expression Design file. I want to be able to open the file's containing folder, then switch to thumbnail view, and the thumbnail will be displayed as the image for the file.

View 3 RepliesI have a vb.net project which i have inserted pictures and video. I inserted a video clip using the Windows Media Player control and it does work. The issue i have is that i can't move the program to another computer because the pathname for the video will be wrong. I know i could change the pathname when i move it but this is not practical because i need to present this program. Does anybody know how to make the video accessible no matter what location the program is at?
View 6 RepliesI am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.

The above code is used by me to encrypt .avi files and it worked very well but the problem is that if the size of my video file is greater than 200 mb memory overflows probably as the code copy the whole input file into ram and then process it hence it put limitation of hardware,is there any better way to do it so that files > 200 mb could me encrypted in PCs with 1gb ram?
I have created my own application for organising my video library. when the application starts a datagridview displays all of the videos in my database. i can't get it to display the duration of each video. i assumed i'd be able to loop through each row in the datagridview and use the FileInfo class to look up the properties of each file and get the duration from there because if you look at the properties of any .avi and then click on Details you can see the duration of the video but i can't figure it out.
