Stored procedures
Starts the execution of a program (an executable for example) from the current application.
WINDEVJavaUser code (UMC) This allows you to retrieve:
  • the return value of executable with the exeReturnValue constant.
  • the process identifier, also called PID with the exePID constant.
WINDEV Remarks:
  • From Windows Vista, the applications may fail to start if the UAC mechanism is enabled. See remarks for more details.
  • In 64-bit Windows, the access to a system directory from a 32-bit executable can be performed in a directory that differs from the expected one. See Native 64-bit and native 32-bit for more details.
Example
WINDEV
// Start Notepad in default mode
ExeRun("NOTEPAD.EXE Readme.txt")
WINDEV
// Start a program with long name containing space characters
// For example: Word with "My documents" as working directory
 
// Solution 1: Using the syntax specific to the multiline strings
// (to avoid doubling or tripling the quotes)
IF ExeRun([
"C:\Program Files\Microsoft Office\Office12\WINWORD.EXE"
], ...
exeActive, exeDontWait, SysDir(srMyDocuments)) = False THEN
Error(ErrorInfo())
END
 
// Solution 2: Doubling the quotes
ExeRun("""C:\Program Files\Microsoft Office\Office12\WINWORD.EXE""", ...
exeActive, exeDontWait, SysDir(srMyDocuments))
WINDEV
// Start applications with a file in command line
// Name of application to start
sAppName is string = "C:\Program Files\Adobe\Photoshop 6.0\Photoshp.exe"
// Name of the image to open
sImageName is string = "C:\Users\My Name\Pictures\Buildings\IMGP0993.JPG"
 
// Equivalent to "Start Run"
// We must get a character string containing "" such as:
// "C:\Program Files\Adobe\Photoshop 6.0\Photoshp.exe"
// "C:\Users\My Name\Pictures\Buildings\IMGP0993.JPG"
IF ExeRun(StringBuild([
"%1" "%2"
], sAppName, sImageName)) = False THEN
Error(ErrorInfo())
END
Syntax

Running an executable (in locking or non-locking mode) Hide the details

<Result> = ExeRun(<Program name> [, <Mode> [, <Wait for end> [, <Working directory>]]])
<Result>: Boolean
  • True if the program was started,
  • False otherwise. ErrorInfo returns more details about the error.
<Program name>: Character string
Name of program to start with its path and/or the parameters that must be passed to the program (if necessary).
  • If no path is specified, the program is sought in the current directory, then in the Windows directory and in the directories accessible by PATH.
  • If the executable corresponds to a long name with space characters, the following syntax must be used:
    <Program name> = " " " Long_name_with_spaces" " Command_line"
<Mode>: Optional integer constant
Mode used to start the program (no action on the DOS programs).
exeActive
(Default value)
The program run is active, it "takes control" over the current program.
exeIconizeThe program run is inactive and it is minimized.
Java This constant is not available.
exeInactiveThe program run is inactive: it is run while the current program keeps focus.
Java This constant is not available.
exeMaximizeThe program run is active, it "takes control" over the current program (the execution window is maximized).
Java This constant is not available.
Java The program run is always active: it is run by "taking control" over the current program.
<Wait for end>: Optional Boolean constant
Configures the time-out before resuming the execution of the current program:
exeWaitThe current program resumes its execution when the program run is over.
exeDontWait
(Default value)
The current program and the program run are run in parallel.
<Working directory>: Optional character string
Working directory of application to start.
WINDEVWindowsLinuxJavaUser code (UMC)

Starting a program and retrieving a value Hide the details

<Result> = ExeRun(<Program name> [, <Mode> [, <Element to return> [, <Working directory>]]])
<Result>: Integer
Sought value:
  • Return value of the executable if <Element to return> corresponds to the exeReturnValue constant.
  • PID of the executable if <Element to return> corresponds to the exePID constant.
ErrorInfo is used to find out whether an error occurred.
<Program name>: Character string
Name of program to start with its path and/or the parameters that must be passed to the program (if necessary).
  • If no path is specified, the program is sought in the current directory, then in the Windows directory and in the directories accessible by PATH.
  • If the executable corresponds to a long name with space characters, the following syntax must be used:
    <Program name> = " " " Long_name_with_spaces" " Command_line"
<Mode>: Optional integer constant
Mode used to start the program (no action on the DOS programs).
exeActive
(Default value)
The program run is active, it "takes control" over the current program
exeIconizeThe program run is inactive and it is minimized
exeInactiveThe program run is inactive: it is run while the current program keeps focus
exeMaximizeThe program run is active, it "takes control" over the current program (the execution window is maximized)
Java This parameter is ignored. The program run is active, it "takes control" over the current program.
<Element to return>: Optional constant
Configures the function result:
exeReturnValueThe current program resumes its execution when the program run is over. <Result> corresponds to the return value of executable.
exePIDThe current program and the program run are run in parallel. <Result> corresponds to the identifier of created process (also called PID) if the executable was successfully run, 0 if an error occurred.
This identifier can be used in some APIs for example.
Java This constant is not available.
<Working directory>: Optional character string
Working directory of application to start.
Remarks

Using a command line

To pass parameters in command line to the executable run, you must specify the name and full path of the executable to run.
If the program run was developed with WINDEV, CommandLine allows you to retrieve the command line.
WINDEVWindowsLinuxJavaUser code (UMC)

Using the exeActive constant

If the process where the application is run (with the exeActive constant) runs a code allowing the calling program to regain focus, the called program loses control.
In order for the called program to keep focus, you must not:
  • call another window or dialog box after the call to ExeRun,
  • call ReturnToCapture after ExeRun.
In addition, the Button control (if there is one) whose associated "Click" event contains a call to ExeRun must not be "Tab Stop" ("Accessible by TAB" in the "GUI" tab of the control description).
WINDEVWindowsLinuxJavaUser code (UMC)

Return value of a WINDEV executable

A WINDEV executable can return a value. To do so:
  1. Create an Integer variable global to the project.
  2. Initialize this variable with the value to return.
  3. Return this variable with the keyword RESULT in the project closing code.
WINDEVWindowsUser code (UMC)

Starting an application in Windows Vista (and later)

If the UAC is enabled, the application that is using ExeRun to start another application must have higher rights than the application that is started.
For example, a first application started with the administrator rights can start a second application that requires no specific rights.
If the second application requires greater rights than the application that starts it, the second application may fail to start. Windows proposes to enable the management of compatibility with Windows Vista. If the management of compatibility is enabled, the second application will be run during its next startup. You also have the ability to use ShellExecute.
WINDEVWindowsLinuxJavaUser code (UMC)

Various

  • ExeRun does not modify the current directory. The current directory before running ExeRun is identical to the current directory after running ExeRun.
  • If the program run ignores the specified runtime mode, the program is run in exeActive mode.
