View 1 RepliesI wanted to make a screen recorder (not screen capture) program, but I am not entirely sure how to get it started. I have seen many videos and things on how to make one, but all of these just take multiple pictures and then don't compile them into a movie file, and I don't want to take many pictures (unless that is the only way possible.) I am using Visual Basic 2010 Express and I have looked at the Windows Media Encoder, but I can't seem to figure out how to use/implement it (yes, I have downloaded and installed it.) Maybe I can use some kind of ActiveX control?

I have a TreeView populated with some nodes, and some of those nodes have children. Is it possible that when the node, or child is selected that the entire node including the children be selected? I still want to deal only with the value of the root node, but for the UI I want the root + children to be selected.
View 5 RepliesWhen I first saw Silverlight, I thought that there was a How Do I: video that demonstrated how to capture the PC screen and save it in a WMV file. Since I can't find anything like that I'm wondering if I was dreaming or it has been removed from the Net. My goal is to create a video capture Class that I can use to demonstrate my program and add the feature in my program so the user can record any issues they are having with my program and send it to me. This way I can see what issues they are having with my program.

I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it.

'Dim FiletoDelete

screenGrab.Save(LogLib & lsFile)
I'm trying to develop a windows form app which will take a screen shot every 30 seconds for about 45 minutes. After 45 minutes, the user will click Finish, and these screenshots will be uploaded to a database. I don't want anything that simulates a PrintScreen key press, because I don't want to alter the users clipboard. The second issue is, for users with multiple screens, I'd like to capture the entire screen image, not just from the primary screen. I'm using Visual Basic .NET 2005.

I'm working on a project. I've gotten all the kinks out of my Client/Server tcp chat. But I need to find a way around this problem.
In my chat room, you can have other users view your desktop remotely. But I'm having a problem with this.Does anyone know how I would get a screenshot or possibly video of the desktop and write it to my stream? I can convert it to a string already. and my old method used screenshots written to the disk. I would like to avoid touching the hard drive if possible, so that means extracting the screenshot/video from memory.

I did a search on capturing screen shots in vb.net amd I was wondering if there is a straight forward way to capture the active window?

I want to save it to jpg format.
