Name of the program to execute, together with any required arguments and command-line switches. PathName can also include the drive and the directory path or folder. If you do not know the path to the program, you can use the GetFiles to locate it. For example, you can call My. GetFiles "C:", True, "testFile. A value chosen from the AppWinStyle specifying the style of the window in which the program is to run.
MinimizedFocuswhich starts the program minimized and with focus. A value indicating whether the Shell function should wait for completion of the program. If Wait is omitted, Shell uses False.
How to run Command Prompt commands from VB.NET?
The number of milliseconds to wait for completion if Wait is True. If Timeout is omitted, Shell uses -1, which means there is no timeout and Shell does not return until the program finishes. Therefore, if you omit Timeout or set it to -1, it is possible that Shell might never return control to your program.
An integer containing the program's process ID if it is still running. Shell cannot find the PathName file. PathName is Nothing. The following example uses the Shell function to run an application specified by the user. Specifying AppWinStyle. NormalFocus as the second argument opens the application in normal size and gives it the focus.
The return value of the Shell function depends on whether the program named in PathName is still executing when Shell returns. If you set Wait to True and the program finishes before the timeout expires, Shell returns zero. If the timeout expires, or if you omit Wait or set it to FalseShell returns the process ID of the program.
The process ID is a unique number that identifies the running program. This can happen, for example, when you attempt to run a bit program, such as command. For a workaround, you can run a bit program that calls the desired bit program. In the case of command. By default, the Shell function runs the program asynchronously.
This means that a program started with the Shell function might not finish executing before the statements following the Shell function are executed.
If you want to wait for the program to finish before you continue, set Wait to True. A process can return an exit code when it terminates. However, you cannot use Shell to retrieve this exit code, because Shell returns zero if it waits for termination, and also because the process runs in a different object from Shell. To retrieve the exit code from a process, you must write your own code to initiate the process and wait for termination.Iam trying to call a vb.
Net exe will return either 0,1,2 or 3 based on the steps it executed. Iam calling this exe via Shell command in VB6. How to get the return value of the. NET exe in VB6. Keep in mind this is more of a VB 6.
I don't see the how you are generating the exit code from the VB. NET app but I will assume you are doing it correctly. In any event, you have to use API function calls to get the exit code when the calling app is written in VB 6. Don't use Shell. The Process class will do everything that Shell does, plus it includes methods and properties that enable you to detect the return value from the EXE.
This forum is not for VB6 code, that it is a VB. Net exe does not change anything to the problem. It could have been a Java program in the same case. I would think the solution would depend on how the. There is an answer to this question in the FoxPro forum, which may or may not be relavent.
Run "test. If the. Most probably not, it seems that some contributors did not read your question, you have to do this with VB6 code and that is off topic in this forum. Your question implied that you had control over the VB6 program code, but not the VB. Net program code. If that is so then the only solution is as advised above - rewrite your code in.
Net and use the Process class. Do you have control over the. Net application code? Your VB6 application can then poll for that change - for instance looping to see if a file with a certain name appears in a certain folder, and then reading that file to determine the exit code. But that assumes that you can change the. Net application, and since it involves making a change to both applications, and the result is not particularly reliable in any case, rewriting the VB6 application in.
Net is still the most attractive option. I tried using the code that was provided in the link which you provided.
How to use DOS command in vb.net
This is called a command line interface or CLI. In Windows, the shell is commonly known as the Command Prompt. To access it, click on the Windows button and type cmd Windows Windows finds the program for you, so click on it to start it. In other versions of Windows the process for starting the Command Prompt is similar. Just search for cmd. Commands like dir, copy, del etc are known as internal commands because they are built into the shell - they are part of the code that forms the shell, not separate programs.
Programs like Excel, Notepad etc are known as external commands because they are programs in their own right, but can be called or executed from the shell. Program can be the name of an internal or external command or a script. It can contain any arguments or switches required by the program, as well as the drive and path to the program itself. WindowStyle determines how the window of the called program behaves.
WindowStyle is optional but if it is omitted, the program starts minimized with focus. You can specify the WindowStyle using a constant or the actual numeric value, as shown here:. Focus is where keyboard input is sent to. If focus is on Excel and you type, the characters appear in Excel. If focus is on Notepad, the characters appear in Notepad. When you use Shell it returns a Variant Double data type that contains the process ID of the program you called.
You can use this PID to terminate the program later. Using vbNormalFocus starts Notepad with its most recent size and position, and changes focus to it. In this example I'm calling a batch file Text Parser. All of those """ look a bit strange but let me explain. The first and last " mark the beginning and end of the string that specifies the program being called, including any parameters, switches and file s it will use:.
When this is passed to the Shell one of the double " is removed so what is actually seen in the Shell is. To call an internal command like dir, you must start an instance of the actual shell, which in Windows is cmd.
You then say that you want to use the dir command. You can terminate cmd later. Calls to the Shell are executed asynchronously, VBA will make the call and then continue without waiting for whatever program you called to finish whatever job you asked it to do. This probably isn't an issue if you are just trying to open a text file in Notepad. But if you are say, trying to list files in a directory and then you want to import the resultant CSV into Excel, you need to make sure that the CSV file is complete before you do that import.
One way to do this would be to make your VBA sleep or pause. Make sure that you use error handling when making Shell calls. Just in case the program or file you want isn't in the location you expect, or is missing altogether. The sample workbook I've prepared contains several examples of VBA Shell calls including the use of error handling and terminating programs you have started.

The internal commands are not working.Runs an executable program and returns a Variant Double representing the program's task ID if successful; otherwise, it returns zero. The Shell function syntax has these named arguments :.
If the Shell function successfully executes the named file, it returns the task ID of the started program. The task ID is a unique number that identifies the running program. If the Shell function can't start the named program, an error occurs.
By default, the Shell function runs other programs asynchronously. This means that a program started with Shell might not finish executing before the statements following the Shell function are executed. This example uses the Shell function to run an application specified by the user. On the Macintosh, the default drive name is "HD" and portions of the pathname are separated by colons instead of backslashes.
