Create An Application That Records Screenshots Every 50 Milliseconds?
Jun 2, 2012
I am trying to create an application that records screenshots every 50 milliseconds... And It works below:
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim b As Bitmap = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)
[Code]....
But after 30 seconds I see an ArgumentException on the second line...
Does anyone have a solution or an alternate method of capturing the screen like this?

I am using the web browser control to generate screenshots of an intranet application developed in ASP.NET.
The screenshot is generated, compressed and then stored as a BLOB in the database. When I developed this facility I investigated the best way of compressing the image (to the lowest byte size), however the images still seem to be too big as the database table is growing larger than I hoped. I am using the TIFF format, but I am now thinking that this may not be the best as it is used by photographers (who I assume require good quality photographs). Here is the code to compress the image (before it is stored as a BLOB):

i have a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found. For example i added a button to clear the textfields, and when i ran the application the records i have added earlier were not found.

How do i insert the images during an customize installation?
For example, when i was installing Skype, screenshots of Skype appeared during the installation. How would i make that during my installation, with images appeared and disappeared just like skype. I know i could use code to bring back and front, but that is not how i wanted it to be. I tried that code before, but doesnt look good enough.

I'm looking for visual basic.net code (for visual basic express) to take automatic screenshots (timeout=60 seconds) for application testing. But every code has a lot of bugs:For example: [URL]Errors like:
Error 1 'Protected Overrides Sub Dispose(disposing As Boolean)' has multiple definitions with identical signatures.
Error 2 'Private Sub InitializeComponent()' has multiple definitions with identical signatures.
Error 3 'components' is already declared as 'Private components As System.ComponentModel.IContainer' in this class.

I have a screencasting program where it takes 10 screenshots every second and saves it to a temporary directory then through ffmpeg the series of images are compiled into a video format. My problem is that due to the computers processing power or the size of each screenshot and its quality it sometimes takes longer than 100 Milliseconds to create one causing the whole video to be off balance. How can I ensure 100% that 10 Images will be stored?

Usually when I need to create a DB with excel files(in order to get records that I need), I used following
HTML
Excelconnection = New OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; data source=" + mypath + "; Extended Properties='Excel 8.0;HDR=Yes;IMEX=1'")
Excelconnection.Open()[code]....
where mypath contains path of excel files.Now I have a file with no extension where structure is: each record is separated by space and row are more than 65535.I saw that with csv file I can solve this issue but I don't know if OLEDB connection to csv file works fine.I don't want to create several sheets.

Basically I have created a windows service using VB 2008 where I am trying to capture screenshots periodically.
The timer is working fine and I have tested this.
The purpose of the service is to monitor the desktop over night when the user is logged off, by capturing screenshots and saving them to file. This is so admin can be alarmed about security breaches etc.
The problem is is that I have not found a way to capture desktop screenshots as a windows service (or otherwise) while the windows logon screen is active (i.e: when the user locks the computer). I have used google extensively but to no avail

I am essentially trying to create a list of records in VB.net using the 1.1 framework.It seems that I should be using an object even though I have only properties but no methods (more like a traditional record), I would like to store a list of objects, how can I create the list and add an instance of the object to the list.I do have sample code that almost works but it is too poor for public display.

I'm working on a client application (server is out of my control) that connects to a server and exchanges query/command datagrams. 'Milliseconds Count!' according to my project specification, meaning that the more we can shave off a send/receive process the better.
I understand that there are physical limitations like network bandwidth, internet latency, etc. Even so, I have a strong gut feeling that a lot of the latency I'm seeing is directly related to processing; it seems 'out of phase' from the latency of other network operations (albeit with significantly smaller datagrams). IE: A standard 32 byte Windows Ping returns in about 5ms consistently, our query/response datagram (468 bytes out, 1500 bytes back) returns in about 15ms consistently.
I'm also working with multiple threads to speed things up as much as possible at the client side, and it seems the more threads are involved the more latency is generated (I've seen up to 70ms of additional lag when using 3 threads as opposed to 2). In a recent Google I found something that I only glanced at, that said something about a limitation in Windows System Timing where some claim was made that any System.TimeSpan < 10ms was effectively going to be a 10ms Timespan because the Windows System Clock only 'Ticks' every 10ms. I wasn't paying attention at the time, but now I'm afraid it might be relevant and I can't find it again.

Black Screenshots Games Counter-Strike anticheat?

I'm working on a program which will allow users to take screenshots of full screen games, such as Call of Duty, Battlefield 3, etc. However, I'm having two issues with my code. First off, I'm having to press the shortcut twice, instead of once like my other shortcuts. This only occurs when the code below is actually in the handling sub. If I just have a messagebox show when the shortcut is pressed, it works every time. Second, whenever I take a screenshot, it either comes out completely black, or takes a shot of my desktop, even though there is a game running in the foreground. I have looked around, and it seems that printscreen is the only way to get a screenshot of a game through vb.net.
My code is below.
Private Sub game_Press(ByVal s As Object, ByVal e As Shortcut.HotKeyEventArgs) Handles gamewindow.press
Dim gamewin As RECT
If GetWindowRect(GetForegroundWindow, gamewin) Then
Dim bmp As Bitmap

In my VB6 programs (internal to our organzation) I have always liked taking screenshots upon the occurence of an error to give me more clues as to its cause but somehow I have read somewhere that it may be in violation to some law (privacy / data protection).In the project I am currently developing and it will be for marketing I have used the same method but upon reading about the warning I am now somehow hesitant to use it although it has proved useful in the past.

Create a class to deal with records from the Classes table, much like the Student class we created in Lecture #17 handles Students records. The name of the class should be Ualb_Class (note we cannot use Class, as it is a reserved word in VBA). All of the fields should have corresponding properties. There are few considerations:
The class (course) code, department code, and course number are set at Initialize, so there is only a Get property method for those
The property for Meeting Day only accepts one of the values defined in the table. You can decide whether to accept an integer value or a string value of the days represented.
You are also to code the Initialize method, much like we coded the Initialize method for the Student class in Lecture #17. In the Initialize method, you will use the InputBox function to obtain the department code and course number. use a different InputBox for each value, so you don't have to mess with separating the single text value returned from that function. The Course Code will be obtained by using a function that has already been created, called GetNewCourseID. It has no parameters.
