View 2 RepliesI'm using a picturebox to display the video captured from my webcam. I tried out two codes:
1) [URL]
The code in this forum by kaymaf. it does not work at all! there is no video displayed at all. Also, i'm currently using a PixeLINK 1394 Camera to get the video, but this is not shown in the list of cameras. It shows : Microsoft WDM image Capture (Win 32). Are these the same?
2) [URL]
This code works the first time i run it. But the second time it gives me a listbox of camera to choose from and then does not display any video. The screenshot is as displayed:

Is it possible to send information to a USB Video game controller in VB.Net? The kind of information I want to send to it is information causing the device to think that a button is pressed on the controller when it really is not. Or even better, is it possible to make a USB wire that connects to your computer and another USB port on something such a computer and send information that a video game controller would send to the other computer or whatever? Basically what I want to do is emulate a guitar hero controller sending the data of the buttons being pressed to an xbox 360 console.
View 6 RepliesHow do I create 7-Zip archives with .NET?
I'm looking for ways to do compression and decompression in 7z format via code in VB.NET and C#. Is there any library or .Net code for this purpose?
I know there are GZipStream and DeflateStream in .Net but I want 7z format for better compression ratio.
I'm currently working on a utility software, file compression, with VB.Net. And using an open source library to compress and decompress files - DotNetZip - and already running.
My friend told to make it unique and not traditional, that I make the output compressed files cannot be opened with other compression software. Now my question is... is it possible that way? Using an open source library which the output format is ".zip"?
I first thought that changing the file extension of the compressed file to unknown format so it can't be opened when you try to decompress it, unfortunately, using the "Open With..." function of windows it could still be decompressed.
Is it really possible? OR what other features can I add that WinZIP doesnt have yet? I compared my work to WinZip since the same output is ".zip".
I would like help to compress a file with zlib. I have have searched google for ages and found losts of examples but i can't get any to work in VB 2008 Express. I am also not sure which version of the dll to use as there seems to be a few for VB.Can someone post some code that will work in VB 2008 so i can see how to do it and also a link to the dll that you used.
View 5 RepliesI'm wanting to make a program to rip dvd's but more importantly to store them so the user can watch them when they want. To keep the cpu's memory down I figured I can compress the dvds when the person just has them sitting there and then decompress them when the user wants to play them. I've kinda looked into gzipstream, but would that really work? Should I take a different route?

We need to conditionally disable GZIP compression if user's browser is IE6 (it hangs browser for 5min) in few pages of larger site. Server is IIS7 and has compression for static content turned on - want that compression left working if user agent is not Mozilla/4.0. ASPX code sample anyone? Alternatively, code to conditionally redirect to the same page on another site (could create another virtual site with compression disabled) but need to pass all parameters (GET/POST).

I 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.

View 9 RepliesI have a WCF Windows service that provides data to 250+ PDAs via compressed datasets and was looking to redevelop both the service and the mobile application to use Entity Framework 4.x models. In order to keep performance acceptable when sending/receiving data on the PDA I need to keep the data size as small as possible and was wondering if its possible to compress a IEnumerable from the WCF windows service? From previous experience with the datasets I got a 80%+/- compression rate and even decompressing the data on the PDA achieved an overal 50% performance importment so retaining similar levels of performance is critical. Could I use a binary serializer and then compress the stream?
