Using TCP/IP - Application For Playing Back Recorded Clips From Dvr
Mar 2, 2010
I am developing and application for playing back recorded clips from dvr. There will be 10 persons reviewing the recorded clips all the time. When the person want to review a particular camera recorded clip, he will send a command through COM to my application. Then my application will read the data from COM and connect to dvr and send data to the dvr. If only 1 person is doing the operation my application works fine. If 10 persons continuously working, then my application is getting very slow and the response time back to the person is high which will make the person frustrated to use the software.
Now, when ever I receive data from COM I'm adding into arraylist and I'm processing one by one. I've 10 forms in my application and when ever I receive data from person1 I'll send that data to form1 and person2's data will be send to form2 and so on for processing. What could be the better way to write my application in order to make the response time to the user faster so that, they'll get the recorded clips faster?

How would I go about saving a persons mouse click. Here is how I would like my program to work: They open my program. They go into their program they want to record mouse clicks on, and they press F9. They click however many times, and it records each mouse click. They press F10 to stop recording. They can choose the delay, in milliseconds, between each mouse click. They get the data in a text box. They can save this info in a text file and use it alter if they want to, to play it back.

I'm looking to see if anyone has a good reference for a third-party add-in that will allow me to play .mp4 video files inside my program without a need to embed a web browser in my program.
I have no problem buying it (well that depends on the cost of course!), but I want that when I distribute it, I include their .dll files and it'll work on the user's computer without anything else needed.

I have a program that speaks wave files. This works problemless with the Soundplayer class with the following code:
Sub MyPlayWav(ByVal WavFileName As String, ByVal StartPos As Long, ByVal EndPos As Long)
Dim wp as new SoundPlayer
wp.SoundLocation = WavFileName
wp.Play
End sub
The soundplayer does however not seem to have a method to play the wave from position StartPos to position EndPos and achieving just that would mean quite a reduction in downloads of these files.
The soundplayer does have a stream object, and that does have a seek method, suggesting that there might be a way to accomplish this, but how?
I plan to include other media files as I am developping the project, and I guess I will be confronted with the same problem.

I am working on a VB application, where I have embedded some video clips using the Windows Media Player Active X control and have it set so on the form it will play one video file and then I get control back from the application.
The code that I have for when the form loads is: Do While Not System.IO.File.Exists("C:TempAU_N_015.wmv")
Loop
AxWindowsMediaPlayer1.URL =
"C:TempAU_N_015.wmv"
However, I have a couple of different situations that I would like to be able to accomplish in this application that I am unable to figure out how to handle 1.) After the first video plays, I would like to play a second video (which is stored in a separate file) prior to user input 2.) After receiving user input, I would like to play video clips that will be conditionally set based on what the user does

I do get that I'm going to need to "thread" them separately, but I've been unsuccessful so far.
I get the audio clips to play, but when one starts, the other stops.
This is code that's playing the audio, derived from examples in preior postings[code]...

How can I take recorded coordinates (x,y) and place them into an array? I have the variables set up and everything, but I am unsure how to declare the array for this purpose and how to take what I have in the array and graph the coordinates later on.
Here is the relevant
vb.net
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
TextBox1.Text = TextBox1.Text + 1

Can a media player written in VB be modified to do this: randomly choose an avi file from a directory or subdirectory, choose a random starting point within that file and then play a clip of a random length (within user defined parameters) then without prompting repeat this sequence?
I would like just such a media player but there doesn't appear to be one already out there so my only other option is to write one myself. I know nothing about VB and last programmed in BASIC in the 90s. Before I invest time and effort in learning VB I need to know if it can actualy do this at all.

How you record a screen and then output the recorded frames in a .avi file or .wmv, doesn't really matter what kind of file.

I would like to have a label's text recorded into a database when my button is clicked. I do not yet understand the database connection. I have created the db, and have the following
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Conn As String = "Provider=Microsoft.SQLSERVER.CE.OLEDB.3.5; Data Source=c: empTestDB.sdf;"
Dim tConnection As New OleDb.OleDbConnection(Conn)
[code]....
When I try to test this the .ExecuteNonQuery() becomes highlighted and says the given type name is unrecognized. My table is setup as table1 and the only 2 columns are datetime and temperature. I want the label text to go to temperature and I would like somehow the time the temperature was taken to go into the datetime field. I had the provider=microsoft.jet.oledb.4.0, but I changed it since I thought this was the one to use.

I have an application that continously records audio for several hours. I want to be able to listen to recorded material but not necessarily in real time. I have tried to just copy the file being recorded to a new file with overwrite and the copy obviously gets done (filesize changes) but when I try to listen to the copied file my player just 'blinks' and nothing more happens. If I however close the recording, the copy also gets playable. My idea is that copying a file in use just creates another file in use. If this is the case how can I close the copied file?

Iw ould like to know how to make it so every time you click on a button a different outcome can happen from the opens i gave the application.such as: when i click button 1.i will want it to either close the application or show a textbox but the outcome should be random out of the two.Like a dice if you get 1, 2, 3 the application will execute command "Me.close()" but if it rolls 4, 5, 6 it will execute the command "textbox1. show()"

I would like to try and implement a feature wherby once you have logged into an application (straightforward winforms application) and had your credetials verified the application would then force you to log on again if no activity had been detected in the application for a certain number of minutes. In essence I want to provide some extra security for those occasions when users get up and wander away from their machines for prolonged periods.
I have all the logic for logging into the application, it's just the checking for no activity over a given period and then forcing the user to log back in again that I'm not having much luck with.
