"Component menu already exists" error

EaP · Post by **EaP** » Tue Dec 07, 2004 5:32 am

We have a macro that is used a lot and is run from a hot key, the problem is that sometimes people forget that they have already pressed the hot key and it causes an error "Component menu already exists" and MS has to be closed and restarted. My question is there a way of telling if the dialog has already been loaded or the hot key has already been pressed, I'm very new to this and any help would be greatly appreciated.

Another scripting tool offers a "single instance directive". Just to explain what I'm talking about, check its syntax here:

#SingleInstance
--------------------------------------------------------------------------------

Prevents more than one instance of a script from existing simultaneously.

#SingleInstance [force|ignore|off]

If #SingleInstance is in effect without the force or ignore option, attempts to launch the script while it is already running will display a dialog box that prompts for whether to keep the original (old) instance or replace it with the new instance.

If something similar isn't available within Macro Scheduler - feel free to request it

Like this:

IfWindowOpen>Dialog1
else
Dialog>Dialog1
Caption=Dialog1
Top=239
Width=449
Left=163
Height=250
Button=msButton1,136,56,75,25,0
EndDialog>Dialog1

Show>Dialog1,res
endif

Or this:

ReadIniFile>inifile,settings,running,val
If>val=FALSE
EditIniFile>inifile,settings,running,TRUE
..
.. macro code here
..
EditIniFile>inifile,settings,running,FALSE
EndIf>

Or use a registry key and use the registry functions.

I find setting and reading INI files to be very flexible for triggering and/or monitoring many events.. Can also include a MSG box with timeout indicating already running.
