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]...

I use a single instance in my application. What if I give command line arguments to the exe of my program, so I can be selective in what was given command line in my program, but still single instance?
Example:
test.exe /show
When the command /show, then my program will
Form2.Show
Form2.BringToFront

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:

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"

I am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

I cannot seem to wrap my head around the SendMessage function/method. What I am trying to do is send keystrokes to an instance of webbrowser1 within my vb.net application. Can someone give me a decent example of the code I would need to create to process this using the keystrokes below.

I have a single instance database app that emails out notifications. I would like to add a link in the emails that when clicked would open up the app and go to the section of the program that its supposed to go to. I implemented my own URL protocol so that links starting with my codewords get passed to my EXE. So far so good. I then parse the URL and pull the keyword and identifier out to open that section of the program. So if a user clicks a link like this:
MyApp:LoadCompany?ID=323
My application will start, it will grab the arguments (LoadCompany?ID=323), pass this to my load company routine and then load up company ID 323. Works great.
Now the issue is if the program is already open I still want the links to work but since it's a single instance app it just closes the second app. How can I add something ot the app to watch for this or receive a message from the second app? I know I will need to check status of what I'm doing and make sure things are saved, check security, etc but I can get all that done easily enough. I've found some examples online but none really did what I wanted them to.

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 trying to use the send keys function to send text to another program.I ahve gotten it al working well, except for using () as I know sendkeys doesnt like these.I have tried using the Replace function in several places in my code to replace the ( with {(} and {+0} etc, with various other options tried.But when I run the program, it seems to skip this out completly and leaves them in the string as (, and therefore it errors and wont run.When I step through it, it goes through the function but doesnt alter the strng as it should. This is the code to send the string and my attempt at making it replace the () in the module

The error I get when i try send "Test :)" is: ArgumentExcveption was unhandled "SendKeys string 'Test :)' is not valid"
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 am able to get the commands to work within a terminal emulator.

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?

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.
If e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.
