VBScript - How to Load an App Targeting a Specific File - Problems with .ShellExecute Syntax

objShell.ShellExecute "notepad.exe", "C:\Users\MyName\Desktop\testfile.txt", "", "open", 1

For details on https://docs.microsoft.com/en-us/windows/desktop/shell/shell-shellexecute

Note: Your "app" must support command line arguments.

@ ProfessorJimJam:  

Thx that syntax is correct (I had tried it previously with CustomUIEditor.exe with fully qualified path but received a File Not Found on the file I was trying to open with CustomUIEditor.).

@FabriceLambert:  

You may have identified the root cause of my issue (or I don't know which switches/syntax to use to pass a file argument for 'app' to open).  

How can I find out if CustomUIEditor.exe supports command line arguments.  

I've tried looking in the MS Custom UI XML Markup Specification but didn't spot anything relating to Command Line Arguments (might have missed it).

In attempting to get a list of available command line arguments, I've tried adding " /?" to the fully developed path URL for CustomUIEditor.exe but I get the error in the attached screengrab.  Not sure if the syntax I'm trying in trying to specify the " /?" switch is correct either.

Thx

How can I find out if CustomUIEditor.exe supports command line arguments.

Looks in the application's documentation, or ask the developpers.
If it wasn't designed with command line arguments support, there is nothing you can do.

Searching for "CustomUIEditor command line" on google yelded no relevant result.
Guess it does not support command line arguments.

@Fabrice Lambert:  

Thx.  No luck with documentation yet.

I'm trying a workaround with SENDKeys.

I can get VBScript to open up a fresh window with CustomUIEditor.exe just fine with

set objShell = CreateObject("Shell.Application")appPath = "C:\Program Files (x86)\CustomUIEditor\"
appName = "CustomUIEditor.exe"
app = appPath & appName
objShell.ShellExecute app

with the app open, if I manually press the 'ALT' Key then the 'F' key, I can toggle the file menu.

How can I send a SENDKEYS to this app (ie the active window) created by the above VBscript? (I keep getting Object doesn't support this property or method; I'm a novice in this area so may be trying incorrect syntax).

It seems to me that once the app is loaded, I'm simply trying to interact with a basic window (in Win10).

I'm trying a workaround with SENDKeys.

Better shoot yourself in the foot than doing that !!
You have no way to ensure the application will be displayed and remain on top of all other Windows.

@FabriceLambert:

I realize this is a bit of a hack (though this VBScript I'm trying to get working is for my own use so I don't mind if it's not robust, as long as I can get it to work).

Having loaded the app (ie window appears), what would be the command to simply Echo the name of the active window?  I could start with that.

Presently I don't understand (know) the syntax to Echo the loaded app's Window Title in this VBScript.

Merci Fabrice

Afraid I cannot help further.

@Fabrice Lambert:

Thx for your input just the same.  It's tweaking me to look in a different area.
