Show Realtime Cpu Usage Via Unix Using Top Command
Mar 19, 2012
currently i am working on a project to help our customers troubleshoot our products, our products have the availabilty to be access via telnet, i can use the top command to show
top provides an view of processor activity in real time. This utility reads the status for all processes in /proc each <seconds> and shows the status for however many processes will fit on the screen. This utility will not show processes that are started after program startup, but it will show the EXIT status for and PIDs that exit while it is running.
I am looking to but this into my project in real time and show a graph do you think this can be achived ?

You can easily get the memory usage of the current process using workingset64 However I could not find any event like OnMemUsageChanged so I can display a little mem usage meter that displays live/real time the mem usage value. Updating in a timer every second can be done but looks inefficient. Is there anyway I can get an event or callback every time the mem usage changes ?

I want to run some dos commands (eg: a ROBOCOPY) and show the output from this realtime in a text window to show the user something is happening.The command may take a number of minutes so it's important the output is showing in the VB application realtime, and not just all at the end. Obviously the user will wonder what is happening during this time.

I am working with a very simple (so far..) little program where i use som trig to create a circle using pixels created vith the Ellipse-comand "(x, x, 1, 1)" etc.
But I want to se when the graphics is drawn, just not the finished circle, how do I do that?
I use the "Paint" version of the form. I am a beginner so excuse my poor skills. Shouldn´t this be a very simple little problem?
I work with Visual Basic 2008 Express

I was recently assigned to do some research on how to approach a project. Right now we have an old program written in tcl. From this tcl program ( running on VMS client computer), we are able to run unix commands to execute processes on a unix server. This is done via tcpip. Now, we are thinking of making upgrades to this system . We are wondering if this kind of thing was possible with Visual Basic. Are we able to run a VB program on windows computer to run UNIX commands on a server? If so, what issues might be brought up. If anyone has even the briefest guideline or tip on this,

I am writing an application in VB .NET which calls external executables (written in C++)and passes them some command line arguments. What I need to do is read back their stdout outputs inealtime , i.e. as they run.I am currently using the ProcessStartInfo class and setting the RedirectStandardOutput property to true and reading it back in from a StreamReader. However, I cannot read this back in realtime. Once the process finishes, the StreamReader will allow me to

I'm currently working with a project where I need to transfer the internal audio (sound from the computer) to another computer and play it back there.
I thought of transferring the audio with a TCP server-client connection since I already have the knowledge of how to do that.
My problem now is that I don't know how I would capture the internal audio and how to be able to play it back as a stream on the target computer. I have searched a bit and many people recommend using MCI but I'm not sure if this will work on an "almost realtime audio stream" connection.
So my question is: What is the best way to grab the audio from the computer and then play back the data on another computer (as a stream)? I want to do it in realtime and not "recording" the sound and then send it to the target computer.

I have hit a brick wall with my latest project.In essence the entire tab control is created on the fly, i have successfully added any number of tabs with the tabpage title being filled correctly. my problem however is when i add the content itself to the correct page, i have no item displayed on any tabs and however i can retrieve the contents and change them with code.
My code takes a pricelist xml file from my works website and my code is supposed to allow this content to be edited and returned to the server with adjusted prices to reflect updates in our costing. All the code works except the part to display the data, and consequently the code to use this data to update the array used for the xml while the program is running is not written.

Is there a way to detect whether the value the user is entering using keypress method is within the lower and upper limits?For example, the lower limit is 30 and the upper limit is 112 and the current value the user enter is 33 so the next digit is not allowable because it will exceed the upper limit. On the other hand if the user's current value is 11 the next allowable digit is either 0 or 1 but not above I am current using the below method to allow only numbers. Can i expand this code to meet the above requirement?
If Not "1234567890".Contains(Char.ToUpper(e.KeyChar)) AndAlso e.KeyChar <> vbBack Then
e.Handled = True 'When a wrong value is Entered
End If

I have a text file that is going to store some data in this current project. Instead of having it stored on a location on the PC (like C:Test.txt) - I wanted it to be a .txt resource of the application.Using a streamwriter isn't working when I'm attempting to write to the file. This following code runs without error however when I exit the application and look at the text resource file it remains blank instead of showing "Testing".
Dim Writer As New System.IO.StreamWriter(My.Resource.TXTRESOURCE)
Writer.WriteLine("Testing")
Writer.close()

We have an Oracle 11g R2(UNIX) server. A directory was created on this UNIX box for the purpose of uploading/downloading CSV files.I need to access this directory, programmatically from VB.Net in order to search for a specific file (a log file more precisely) and then open it it programmatically in Notepad from my Vb.Net application. I should also be able to delete or copy it to my local drive.I am trying to find a VB.Net code sample that would allow me to implement this: Read/Write/Open files on an UNIX directory.
