how to creat a client and a server and pass text between them (like a messenger), and it works just fine
so my question is : how do I send a command to the server, for example, open a program (like notpad) or do tasks or search the remote pc or even shutt it down??
note that am not trying to make a trojan or anything like that, I have two pcs and I was just wondering how to do it ?
First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.
I am trying to send a command to a command line and then submit the command. I have been trying without success to get this to work in v2008 Express and v2010 Express, Here is the code I am trying to us:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String _

I am currently using psexec.exe from PsTools to send a command to a remote system to fire a command through a command prompt however I am finding that the shell I am doing does not seem to like the spaces in the path.

I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).
I can only access the external program thru the command line (its not my program) and I must do so from a form app.
I am trying to use the following code. I am able to call a cmd.exe window, but I can't pass the command line my command.
Using mp As New Process
With mp.StartInfo
.FileName = "cmd.exe"

Are there any good books out there that will show someone how to set up a form using Visual basic that will take information and send it to the server and then send a recipient an Email?
View 2 Repliesi'm tying to send email in my application directly by the smtp server but the server doesn't allow me to do that.The application its used by everyone in the company, so i set the smtp client UseDefaultCredentials to True, but the server replies with this when i try to send an email:[code].....If i set the credentials by hand, the server sends the email. So my problem is how to make this work to everyone? I don't want to have one public/friend var all time in the application with the credentials of the current user?

I am new to programming and VB.. so go easy my buffer is about full :) I am trying to talk to a box with serial port and only need to send the command in hex. here is the protocol for the device and my code below it to turn on the box. I am not calculating/sending the correct checksum because if I sniff the string being sent to the box from another piece of software that comes with it I get 04 1C 01 DF (spaces put in for clarity) and it works. my code produces 04 1C 01 21..

View 10 Repliesi have a textbox that my mouse double click's on so it highlight's the text and i need it to copy that text
sendkeys.send({^+C})
i know it's something like that but it's not working for me i just need to send ctrl+c to copy it and i dont know the code's
EDIT> k someone gave me the code it's
System.Windows.Forms.SendKeys.Send("^c")
now i need the space key what is the code for it i tried this and it dident work
SendKeys.Send("{SPACE}")
I am trying to delay the execution of the send key command. In VB script, it was relatively easy:
obj.sendkeys "{enter}"
wscript.sleep 1000
obj.sendkeys "{tab} {tab}"
When I do it via VB express, it is clumping the code together. For example
Threading.Thread.Sleep(5000)
SendKeys.Send("enter was entered ")
Threading.Thread.Sleep(5000)
SendKeys.Send("double tab was input ")
Instead of pausing for 5 seconds, typing the keys then pausing for another 5 seconds, it pauses for 10 seconds and then immediately types the input. I tested this on notepad.
How do I replicate the sleep feature in VB script into VB? There appears not to be a sleep feature in VB Express 2010
I have a program that needs to see if it is already running and if so bring the other instance to the front and then close itself. Now I figured out how to see if another instance of the program is already running using GetCurrentProcess, but how do I tell the first instance to "BringToFront" from the second instance?[code]...

View 3 RepliesI want to exit my GUI application (vb.net 4) using a commandline parameter.I should send thive! from the commandline:
myapplication.exe quit and an already running instance of the application should exit.
Now, I have a mutex detection in place so that I can only have one instance of the application running at a time. It seems that if I send a commandline, it won't work on an already running application; it will only work on one that is launching.
I want to send a simple command, such as "v20" followed by a carriage control character, to a heating/cooling block connected to a desktop computer running Windows XP. I am able to get the commands to work within a terminal emulator. I want to compile a simple program that will be executed by software used to control a liquid handling robot.I've looked at the how to send strings to serial ports in visual basic page and modified that code ever so slightly to send the data that I want. However, it does not work and my heating/cooling block is not changing temperatures.
Here's what I have written:
Sub SendSerialData(ByVal data As String)
data = "n65"
' Send strings to a serial port.

I have a shell extension made in .NET that creates folders (think of it as a context menu New -> New Folder option clone) and uses a InputBox to input the name of the folder from the user. Instead I want to send the rename command on the folder to the already open Windows Explorer window. It should be just like how Explorer lets us name a new folder:
On searching, I found this : Windows Explorer Shell Extension: create file and enter "rename" mode. It says to use the IShellView::SelectItem function with the SVSI_EDIT flag. How do I do that with .NET?
I have a need to construct a command Byte to send to another device using bit wise operations.There seem to be plenty of article on how to do this for indiviual bits using an OR'd constant but how do I do this for values that span multiple bits? eg "Bits 4-1" set the repeat count".so how to I inject a repeat count value of say 7 into my command byte?

I am doing wrong? I am using VB2008/VB.NET to send a command (set to 4 volts) to a Tenma DC Power Supply over an RS232 cable. I don't have documentation from Tenma that lists the commands that the instrument understands, I got "VOLT040" from a program in an older version of VB that someone else wrote for this instrument. The code is below:

This is what I'm trying to accomplish: I have a Point of Sale application that integrates with a credit card processesor. I wan't to remove any user interfacing logic in regards to the credit card processor in the point of sale and add it to a application that sits in the background or system tray. I want to be able to send a command to the background app to popup a form for user input.
For example: User in the Point of Sale clicks a button "Credit Card" at this point it will send a command to the background app say "ProcessCC" which will pass a transactionid and an amount , this will open a form for the user to enter in the credit card information and submit the payment to the credit card proccessor.
Reason: I need to get a padss certification and don't want to submit the point of sale to do it. Rather send the simple background app that will control any credit card processing functionality such as encryption , storing etc. I know it can be done using sockets but was hopping for an alternative solution.
how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
