Windows Shell Run Method from OpenInsight

Here is a useful code example showing how to call the Windows shell run method to open any document that is registered with an application. If the file isn't registered whit an application Windows will prompt to select the application using the same dialog that would normally appear when you double click an unrecognized file.


*Common to hold our control between runs so it isn't re-initialized on each call
common /wscript_launch_control/ wsLauncher, wsLauncherAssigned

If Assigned(wsLauncherAssigned) Else wsLauncherAssigned = ''
If wsLauncherAssigned Else
	*Control not initialized, do it now
	*VBScript to run
	sc = ''
	sc<-1> = 'sub launch(File)'
	sc<-1> = 'CreateObject("WScript.Shell").Run(File)'
	sc<-1> = 'end sub'
	*Setup the control
	wsLauncher = OLECreateInstance("MSScriptControl.ScriptControl")
	wsLauncher->Language = "VBScript"
	Swap @FM With \0D0A\ In sc
	*Add the VBScript to the control
	x = wsLauncher->AddCode(sc)
	sc = ''
	wsLauncherAssigned = 1 ;*Mark the launcher has been setup

*Path of the file to open
FilePath = "C:\temp\test.csv"

*Run the control's VBScript to launch the file.
*Protect the FilePath in quotes in case of spaces in path
x =  wsLauncher->Run('launch', '"' : FilePath : '"')


It also demonstrates how to initialize and re-use a script object using a named common. This isn't required for simple examples but for repeated usage it's best practice to re-use the script control. If this technique interests you more examples are available
