I want to make a screen recorder that takes a screenshot of the screen every so often then compresses the image to an .avi file.This code is what I have made. It doesn't work and I don't really know how to make it work.

I'm trying to make a screen recorder using Visual Basic 2008 Express, and everything seems to be smoothlike... until I actually try to record with it. The actual error I am receiving is as follows.A first chance exception of type 'System.Runtime.InteropServices.ExternalException' occurred in System.Drawing.dll The particular line of code that it seems to be having problems with is the following.
BMP.Save(FileDIR0 + Frame + IMG)And now I will post the rest of the code in case it helps.
Public Class Form1 Private Sub RECScreen_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RECScreen.Tick

I 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 need to create a windows app which will track if the user while visiting the website, is running any screen recorder. If he is, I need to log him out. I have knowledge on c#, vb.net. Can you please tell me if it is possible to track if screen recorder is running on user's computer?
View 3 Repliesmaking a screen recorder. make it take a screenshot 15-30 times a second, and for each shot there will be a text file that will say the location of the cursor when the shot was taken and what the cursor was, like loading or whatever. Then when the user presses save, it will take all the shots, import the cursor in each one and then create an AVI using each of the frames that were initially shot. Another better way would be to take a screenshot with the cursor in it, if thats possible.
View 8 RepliesWhat i want to make is a 1 button screen shot recorder, i have a picture what what i optimally want that was created on vb6. Edit: Ok this is what i want, after thinking about it i realized how it should be done.
Form 1 - initial screen capture button and send to in form2
Form 2 - view picture with save button imagebox
so i know how so take and save a screen shot, what i need to know is how to get it the imagebox and have form2 automatically pop up. What i have so far. [Code]
I was looking up how to make a screen recorder when I ran into a source code that uses Windows Media Encoder SDK. I tried it out and it crashes saying that Data Execution Protection stopped the program. So, I debugged the program and found that when it creates a new instance that this is the cause of the crash.

I have seen that there are many "Mouse & Keyboard Macros/Recorders" out there & I was wondering how they are being created in visual basic. I have looked within the Microsoft forums, but havent really seen any specific coding that works for the kind of recorder that I'm trying to create.

I send a message a while ago and no one answerd, how can I draw directly on the screen (not on a specific window) just on the screen, neither if it's on the desktop or anything else.Is there is any option to bring up the switch between applications window (Alt + Tab), I don't want to use sendkeys because the user need to keep the key down and I just want the user to select the application with his mouse.
View 3 RepliesI have a button btnRegEx that when pressed shows a ContextMenuStrip, similar to the '>' button in the Find/Replace dialog in Visual Studio when you are using Regular Expressions. I have a ContextMenuStrip cms which I show using its Show(x,y) method.
At first I was simply setting x and y (the location of the ContextMenuStrip) to some point next to the button, but I noticed that when the button is close to the edge of the screen it goes off screen. I wanted to prevent that so I built some logic into the x-y calculation. When the ContextMenuStrip width is larger than the 'remaining space left' I simply show it more to the left. Same for its Height of course. I am using the Screen.GetWorkingArea(point) method to determine the 'remaining space left'. As I understand it, it returns the working area closest to the point you specify (to which I pass the button's location).
As long as I stay on my first monitor, it is all working perfectly fine. The problem occurs when I move the form to my second monitor. The contextmenustrip is still showing on the first monitor for some reason...
Here is the code I am using:
vb.net Private Sub btnRegEx_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRegEx.Click
Dim p As Point = PointToScreen(New Point(btnRegEx.Left, btnRegEx.Top))
Dim x, y As Integer
[CODE]...
I have noticed that when I click the button when the form is on the second monitor, the buttons location (p) is calculated with the first monitor's top-left corner as (0,0), even though it is on the second monitor. This way, the GetWorkingArea function returns something like 1280, while the buttons x-location is something like 1700... So, how do I get the buttons coordinate relative to the actual screen it is on, rather than the entire dual monitor screens as a whole?
Is there any way to invert the screen. For example, making upside down or having mirror effect?

View 1 RepliesI want to make something like this but I'm not sure is it possible to run something like this with VLC ActiveX control.My first problem is how to run rtmpdump with that example stream from TextBox, and to run all of that with VLC Media Player.So the command should look like this:
rtmpdump -r (stream from TextBox or any other stream from TextBox) | "C:Program FilesVideoLANVLCvlc.exe" -
BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

View 1 RepliesCurrently I have the following VB.NET code to make a screenshot of my desktop, but it only takes a picture of the active screen:
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("%{PRTSC}")[code].....
The following code is how I execute the above function, if it makes any difference, which I don't think it does:
SaveScreen("C:Lexer_tracescreen.png")
Now, I need to be able to take a picture of the entire screen, not just the focused window.
Now I'm creating at app in VB (Microsoft's, Visual Basic 2010) which will be in full screen but I want to know if I can put all my content in the centre of the screen. At the moment it's at the far top, left of the screen. When the screen size varies I want it will stay in the middle for all shapes and sizes. Like :
<div style="margin: 0 auto; width: 500px;"></div>
But this is for web pages using HTML and CSS.
I'm trying to get coordinates on my screen by holding down my mouse and placing it over different parts of the screen. I'm using the mouse_up and down events in a button to kinda simulate the mouse being held down. The problem I'm running into is that anytime I go past the button's bounds, the coordinates I want stop. This is what I have so far:
