Hi

i am trying to find away to appen to a shell command extra parameters that will be held in push button labels.

for example

I could have loads of push buttons with labels

X 222 X 5432 Y 5443 Y 55353 G 56554

I would need the macro to get the append the label text to the shell command

is this possible?

Macros are an advanced technique. I suggest you read the Libreoffice manuals related to macros first.

@: "... extra parameters that will be held in push button labels..."
Did you also consider to create hyperlinks instead of buttons for the purpose? A hyperlink can also be used to call a subroutine provided by the user.

Sorry. Just tested it and it didn't work the way I tried (and thought to remember).

Hi

I worked out the following and it seems to work for my needs;

Sub My_Remote(oEvent)
oCaller=oEvent.Source.Model
sName = oCaller.Name
sLabel = oCaller.Label
shell("my_remote.exe " & sLabel,6)
End Sub

I still would emphasize that the .Tag property is appropriate for the purpoise. This does not prohibit, of course, to also show part (or all) of this informartion via the .Label to the user.

I use the label as this shows the actual commands that are being sent to the external application. It makes it visually easier to understand.

Of course. (I could anticipate this reason.) You have to do as your needs require.
However, you need to edit your "loads of push buttons" one by one this way, won't you?
Users more acquainted with spreadsheets or databases tend to think of lookup tables for related purposes.

Its a Office Writer Document. Its more of an in house instructional manual, that a user can read about a device(s) function; if they press the button that has the command on it, it then sends this to the remote app, which in turns communicates with other application/devices to demo/test that function. As it stands, I can now just copy paste a Button, change its label to match the function its going to send and bingo.

In addition to what @EasyTrieve said:
When writing a macro for handling a FormControl event you need to provide a formal paramtere for the event. When called due to an action on the button this parameter gets an object assigned that contains all the needed information. Its indirect property .Source.Model gives access to the control (a PushButton in your case) having raised the event. There you also find the .Label string.
Additional advice: The .Label property is what you see displayed on the Button. It may not be the bset place to pass additional information. The object inspector working on any control also has a line titled 'Additional information' under the tab General which is more appropriate for the purpose. However you need to know that the model's property giving access to that information (string) is .Tag in the API.

I did a bit more meanwhile because I got interested in the question requiring probably an approach from a somehow theoretical starting point.
For programmers of user code it is a well known annoying problem to pass parameters to subroutines needing to be called via >Tools>Macros>Run or by an event raised by MouseClick on a sensitive area. Using Calc I prefer cell ranges for the purpose. Working with text douments TextTable can be a (uncomfortable) surrogate.
It's different and much more complicated if there shall be used "many" FormControl, most Likely of PushButton type. To a first view it seems unavoidable to edit every single button pasing information to the Sub to call via the .Tag (or .Label ??) property e.g.
I wanted to find a way to simply create one such button associated with one Sub (that will have to select cases internally), to copy this button and paste it into (e.g) the cells of a table column, and to take the needed additional information after the event raising action from an adjacent column then.
It was a bit challenging, and it isn't satisfyingly efficient. I nonetheless attach this example demonstrating how to do it in prínciple. The included Sub for the disambiguation of control names may be of some interest independent of this special question.

Of course I am interested in solutions proving my attempt unnecessarily complicated.

HI Using the source.model would appear to be ideal, but I cannot find anyway/examples of this property. DO you have any examples? Spent hrs googling and getting nowhere, probably seraching for the wrong thing.

Sorry I don't understand what you expect as an "example for source.model". I described the way to get access to subordinate properties like .Label and .Tag. The "model" itself is a way to talk_of/access the FormControl object having raised the event.
If I find the time I will attach a basic example for a TextDocument containing a button and a Sub called by clicking on it.
