The OpenExternal Activity opens an external document or executable file, also using optional arguments.

[edit]

Description

Open External
Name OpenExternal
Purpose Open an external document or executable file
Category UBIK File Primitives
Returns success of opening the file
Version 2.4+

Arguments

Argument Type Direction Purpose
FileName String In The path to the executable or the document file.
Arguments String In Additional arguments (optional, used to pass arguments for executable files).
WorkingDirectory String In Working directory (optional, used to specify a working directory for executable files). This value is only used in combination with executable files.
TimeOut Integer In Time out value in seconds (optional, to wait for a maximum amount of time for the invoked process to finish). Leaving this value empty or setting it to 0 means that the workflow continues execution immediately, otherwise the specified amount of seconds will be spent waiting for the process to finish.
Result Boolean Out true if process successfully finished, false if not

Usage

The activity is used to open file documents or executable files during the execution of a workflow. It can be used to open and show documents like Excel files, JPG pictures etc but also to execute a batch file if needed.

IC Attention.pngOpening any (proprietary) document type requires that a corresponding application is available on the machine, for example Microsoft Office for an Excel document.

Examples

Open an Excel document

Show the Excel file E:\Results.xlsx:

Argument Value
string FileName "E:\Results.xlsx"

Open image file with explicit application

Show the graphics image file E:\Graph.jpg with a certain image viewer application that allows to pass the additional command line argument "/clipcopy" which copies the loaded picture to the clipboard. Therefore, the needed arguments are simply separated by space characters, consisting of the image file path and the additional argument.

Argument Value
string FileName "C:\Program Files (x86)\IrfanView\i_view32.exe"
string Arguments "E:\Graph.jpg /clipcopy"

Open image file with default application

Alternatively to the previous example, showing the image E:\Graph.jpg with it's system default application can simply be done by specifying it's document path as the file name.

Argument Value
string FileName "E:\Graph.jpg"

Execute a batch file with command line arguments

Another use case could be executing batch files. We have a batch file E:\ProcessData.bat that processes the data of the text file MyData.csv in the working directory "E:\". If there is a problem we want to specify a timeout of 30 seconds for this processing step to avoid blocking the workflow for a long time.

This can be done by defining the following arguments:

Argument Value
string FileName "E:\ProcessData.bat"
string Arguments "E:\MyData.csv"
string WorkingDirectory "E:\"
string TimeOut 30
