How To Send A Command To A Running Application Via Commandline
Nov 10, 2011
I 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 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"

This is the command line I want to use inside my VB.NET program. Look for the running process "mpc-hc.exe" and get the commandline of the running processwmic process where name='mpc-hc.exe' get CommandLineI want to retrieve the output from that command into a string. I know that it could be done natively in a VB.NET program and I have looked at how it was done. However, I cannot get the code to perform what it did in the commandline I have above.

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.

I have recently started playing with sockets, so now i have set up an instant messaging app. it works like it's supposed to however, theres a slight problem. short of arranging for both parties to come online via email or something there's no way for the other person to know that someones waiting for them. So i'm basically looking for a way to send a pop-up message to tell the other dude to get his ass online,is there a way to display a message on a target pc's screen without a client application running and actively listening for an incoming command?

I have an application that has file extensions associated with it. The application has been deployed using ClickOnce. I have checked the associations table to confirm the entry is there and the association is to the 'ClickOnce Application Deployment Support Library'. When the application is triggered using a file with my extension, it does not pass the filename / directory in the CommandLine Arguments, instead you get the executable path of the application.
Which is under ..LocalSettingsApp"Random Strings"MyApp.exe
I have checked the Registry entry to confirm what the extension is set to open with and the application is dfshim.dll. Is there a way to overcome this, or is this just another limitation of ClickOnce deployment?

I have commandline strings that contains application paths and might contain arguments. Some examples:
1. "C:Program FilesMicrosoft Officewinword.exe" "C:some dirdocumentname.doc"2. "C:Program FilesSome Dirapp.exe" /dosomething3. C:Program FilesSome Dirsomefile.exe4. C:somedirsomefile.exe /whatever5. C:Windows
otepad.exe6. someapp.exe
I'm looking for a simple way to split the path to the application and the optional argument.Sometimes the string contains quotes around the path (1&2) and sometimes, even when the path contains spaces, the string does not contain quotes(3). And sometimes the string does not contain spaces in the path (4&5&6), but a space is used before the argument(4). And (6) is a executable without a path. I have to use the environmentvariables the find the fullpath of the executable. This string (6) can also have arguments.Is there a standard function available to do this split?
Note:I have a regex pattern to handle (1,2,4,5,6), but is doesn't work for (3), because of the spaces in the path."[ ]+(?=(?:[^""]*""[^""]*"")*(?![^""]*""))"I cannot control the strings. Some of them come from user input and some of them come from the registry.

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 have this code which gives me all of the information I need regarding tasks, information etc. I have it all shelled into a VB program and I want to be able to run this from one computer and have it return the data from all computers on the domain.[code]I have script that will list all users on the domain, can I implement that or is there an easier way? If I could search the entire domain for a specific file that would work too.At the moment I just need all the data returned to a text file, I am not worried about it being sorted, or how long a process like this would take.

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..

I'm trying to run a command line argument through VB.NET using the Shell() command.I'm trying to use this piece of code:
FOR /R %I in (*.pdf) DO @pdf2swf.exe "%~fI" -o "%~dpI%~nI.swf" -f -T 9
-t -G
Using this:
Shell("FOR /R %I in (*.pdf) DO @pdf2swf.exe "%~fI" -o "%~dpI%~nI.swf" -f -T 9
-t -G ")
However, the interpreter is giving me this error:
Character is not valid. (BC30037)
For the %~ part.I also tried created a string and passing the argument to the Shell() command by using Shell(StringName) but I still get the same error in the string.

My single-instance application has code to auto-start from the command line and open a requesting file with the appropriate extension when it's double-clicked or 'run' - this works fine. Once it's up and running however, what is the recognised way to detect a command line request to open another similar file so I can offer an option box to stay with the existing file or close it and swap to the new one? Can I do this within the main app, or do I need some sort of 'background listening' app to detect this and act accordingly?

How do I make a program run only when it is executed with a command line? For example, if you press WINDOWS KEY + R, and then type in
"firefox.exe -profilemanager"
It will open up Firefox's profile manager. How do I make my program do that, except, if it's command line is "program.exe -letmein" it'll open form2. And if it's opened manually, (by doubleclicking or anything else) it'll open form1.

So I ran into a problem when running a command whose Path contained a space.apparently anything after the space would be treated as a parameter to the command.In the code below, 'path' is the path to the command and par1 and par2 are arguments to that command. The code below works, but could someone tell me why it works?Initially I was creating a literal string by placing around it like so: """string""" , but I needed the fourth quote when passing a variable.How is the use of quotes functioning here?

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
