1. Setting status bar contents from a called script

Assume I have a script A (a GUI script) that calls B. In A I do a GUIINFO to get the handle for the status bar control. I then call B where I want B to be able to write data to A's status bar. I call B with the following:-


PROCEDURE EXPOSE guiwindow status_bar_handle
etc etc

and further down in B I have


DO
	status_bar = 'Default DB2 system is 'selected_database
	guisetctlvalue(status_bar_handle, 1) 
	CATCH SYNTAX
		NOP
END

but this doesn't seem to work. Do I have to have the setting of the status bar in A ? I have other scripts with list controls - there, a call (in B) such as


guisendmsg(progress_fld, 'ADDSTRING', , string)

works with no problem, so I tried with that as well, but to no avail.

Probably need to empty out the messages before you see any change.

3. Can't remember how to do this

I'm running into the same problem in another script. In A, I have


statusbarwidths.1 = 100
statusbarwidths.2 = -1
guiaddctltext('status_bar', 2, 'statusbarwidths')

and in B, I have


PROCEDURE EXPOSE sw_array guiwindow status_bar_handle
.
.
.
	DO
		status_bar = 'Analyzing line 'curr' of 'sourcecode.0
		guisetctlvalue(status_bar_handle, 1)
		CATCH SYNTAX
		NOP
	END

but I never see anything. Note that if I add the code to A


			status_bar_handle = get_handle('status_bar')		
			status_bar = 'Hello'
			guisetctlvalue(status_bar_handle,1)

then I never see anything. If I change the code to


			status_bar_handle = get_handle('status_bar')		
			status_bar = 'Hello'
			guisetctlvalue('status_bar',1)

then I see Hello as expected.

The GuiWindow variable first needs to be set to the handle of the window (containing the status bar).

5. Sorry, my bad

Programming error - I thought I was passing in a valid handle, but I wasn't. Have improved my error handling for that sort of error. Thanx

6. I'm going to add this as an append since I fell over again with the same problem (and error)

The problem (for me) was the fact that I get the handle by calling GET_HANDLE. This in turn looks through a stem variable called wdw_size.

If the control isn't there, then it won't work. Summa summarum - check the procedure called get_control_size_pos:

7. .... plus something Jeff suggested above

If you don't see anything in the status field, try adding the following code
