Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Was just looking into this again to see if I could use it in AA 12.

    This error is coming from the line
    obj.child_enum(a[i].name)

    if you check the functions you will see that 'a' was never defined as an array - this should fix it:

    dim a[0] as p

    and in the other line, try setting a var to the array name instead:

    dim nm as c
    nm = a[i].name
    obj.child_enum(nm)

    When using the 'r' parameter in child_enum() it looks into every control on the form and this causes errors too. So I tried setting it to "f=field;e=this.button_help" but this returned nothing. However if r is set to f without specifying the class, you will at least only get objects that actually have button_help.

    In the IW, although I can get a list of bubble help into an array, I cannot get these scripts to actually turn the bubble help on or off anymore.

    Has anyone else got a working script?

    Hi Tim,
    Glad to see you tried it too, I think it is a great little feature to have.

    Robin,

    I was able to get the right click menu to show the check mark for the menu item. See attached. The attached was redone in V7 as this is the v7 forum and believe that is what you are still using. The form in Selwyn's sample did not seem seem to paint properly in v7. He probably made the sample in v11. :)

    Form 'Customer Information2' does not have any bubble help. That is why the menu never gets a check mark.

    I hope this is what you were trying to accomplish.

    EDIT: Big Woops. :o I had started to respond just after lunch and got interupted and forgot to see if the thread had been updated. Oh well, looks like you had already figured it out.

    Re: Turning Bubble Help for a Form on and off

    To use this in the right click menu, I wanted the Bubble Help menu item to appear checked when it is "ON". But the BubbleHelpState appears to be ON only if bubble help exists for the form, otherwise it is OFF even tho the menu item is selected. I tried making the dim statements for BubbleHelpState global in the functions so I could test this for the check mark - but the result is inconsistent. If I dim and initiate the global variable on startup to ON it appears unchecked (until I use it), whereas when it is set to OFF in the menu definition, it appears checked. Other than that though the functions are working great. I suppose I don't actually need the menu item to appear checked - it just seemed like a good idea.

    Oh and for some reason dimming BubbleHelpState as global and intializing it at startup, causes that variable to appear twice in the variable list. Haven't figured out why yet - no typo that I can see, and I deleted the previous functions so only these two are in use. I often dim global variables again and only one instance of them appears in the list with their current value, so this is curious. Since it is actually a function too, perhaps that makes a difference?

    Edit: Well it is obvious by now I am not the brightest bulb in here. To get the menuitem to appear checked, all I need to do is use the FUNCTION BubbleHelpState() and not the value of the variable I have been playing with. I checked the Window Bar menu syntax and that is what it does, so I tried it and it works! So I am guessing I can get rid of the global dim statements since they are not needed for this feature to work as a menu item.

    Selwyn,
    Thanks so much for making this adaptation. When I first saw these functions a year ago, I knew it could be a menu item, just didn't know how. As I have been working on it myself lately, it occurred to me that once the bubble help was off there was nothing to capture again. Even though the bubble help comes back when the form is re-loaded, which in itself seems curious. I guess that's why you write programs and I just use 'em!

    Re: Turning Bubble Help for a Form on and off

    Here is a revised version of the script that is now easier to use and completely generic.

    There are now only two functions.

    1. No code has to be added to the form's OnInit event.
    2. There are only two functions now: toggleBubbleHelp() and bubbleHelpState()

    To use these functions, you just call them and pass in a pointer to the form.

    e.g.

    Code:
    toggleBubbleHelp(topparent.this)
    or

    Code:
    dim helpstate as c 
    helpstate = bubbleHelpState(topparent.this)
    helpstate will be set to 'on' or 'off'

    you can easily incorporate the toggleBubbleHelp(topparent.this) command in the form's right click menu.

    Here is the code for the toggleBubbleHelp function:

    Code:
    function toggleBubbleHelp as v (obj as p)
    
    dim sh as n 
    dim sv as p 
    sh = obj.SessionHandle()
    sv = session_variables(sh)
    if eval_valid("sv.__bubbleHelp") = .f. then 
    	dim sv.__bubbleHelp[0] as p 
    end if 
    
    dim BubbleHelpState as c 
    if obj.Child_Enum("r;e=this.bubble_help") = "" then 
    	'if no controls has bubble help, then the state is 'off'
    	BubbleHelpState = "Off"
    else
    	BubbleHelpState = "ON"
    end if 
    
    if BubbleHelpState = "ON" then 
    	turnBubbleHelpOff(obj)
    else
    	turnBubbleHelpOn(obj)
    end if 
    	
    	
    end function 
    
    
    
    
    function turnBubbleHelpOff as v (obj as p )
    
    dim sh as n 
    dim sv as p 
    sh = obj.SessionHandle()
    sv = session_variables(sh)
    dim a as p 
    a = sv.__bubbleHelp
    
    dim BubbleHelpState as c 
    if obj.Child_Enum("r;e=this.bubble_help") = "" then 
    	'if no controls has bubble help, then the state is 'off'
    	BubbleHelpState = "Off"
    else
    	BubbleHelpState = "ON"
    end if 
    
    if BubbleHelpState = "off" then 
    	'if bubble help is already off then just do nothing.
    	exit function 
    end if 
    
    'first, capture the existing bubble help
    a.resize(0)
    captureBubbleHelp(obj)
    
    
    'then, set bubble help for all controls to nothing
    dim count as n 
    count = a.first_empty("name")-1
    dim i as n
    dim c as p  
    for i = 1 to count 
    	c = obj.child(a[i].name)
    	c.bubble_help = ""
    next i 
    end function
    
    
    function turnBubbleHelpOn as v (obj as p )
    
    
    dim sh as n 
    dim sv as p 
    sh = obj.SessionHandle()
    sv = session_variables(sh)
    dim a as p 
    a = sv.__bubbleHelp
    
    dim BubbleHelpState as c 
    if obj.Child_Enum("r;e=this.bubble_help") = "" then 
    	'if no controls has bubble help, then the state is 'off'
    	BubbleHelpState = "Off"
    else
    	BubbleHelpState = "ON"
    end if 
    
    
    if BubbleHelpState = "ON" then 
    	exit function 
    end if 
    
    dim count as n 
    count = a.first_empty("name")-1
    
    dim i as n
    dim c as p  
    for i = 1 to count 
    	c = obj.child(a[i].name)
    	c.bubble_help = a[i].bubble_help
    next i 
    
    
    
    end function
    
    
    
    function captureBubbleHelp as v (obj as p)
    	
    dim sh as n 
    dim sv as p 
    sh = obj.SessionHandle()
    sv = session_variables(sh)
    dim a as p 
    a = sv.__bubbleHelp
    	
    	
    dim controls as c 
    'need to take into account that bubble help can not include crlf. so this turns crlf into spaces.
    controls = obj.child_enum("r;e=this.name() + '|' + stritran(this.bubble_help,crlf(),' ')")
    controls = *for_each(x,word(x,1,"|"),controls)
    dim count as n 
    count = line_count(controls)
    a.resize(count)
    a.clear()
    dim i as n 
    for i = 1 to count 
    	a[i].name = word(controls,i,crlf())
    	a[i].bubble_help = obj.child(a[i].name).bubble_help
    next i 
    end function


    here is the code for the bubbleHelpState() function:

    Code:
    function bubbleHelpState as c (obj as p)
    	
    
    dim sh as n 
    dim sv as p 
    sh = obj.SessionHandle()
    sv = session_variables(sh)
    if eval_valid("sv.__bubbleHelp") = .f. then 
    	dim sv.__bubbleHelp[0] as p 
    end if 
    
    dim BubbleHelpState as c 
    if obj.Child_Enum("r;e=this.bubble_help") = "" then 
    	'if no controls has bubble help, then the state is 'off'
    	BubbleHelpState = "Off"
    else
    	BubbleHelpState = "ON"
    end if 	
    	
    end function

    Re: Turning Bubble Help for a Form on and off

    A bit late into this discussion, but what about the exceptions? I mean, to my thinking, it would be rare that someone would want ALL the bubblehelp turned off on a form. I have used bubblehelp as an aid to first time users of an application and also as part of the information of a button's or field's function. The latter I would not want the user to turn off normally, especially if the field or button is not going to be used very often. This is why I have a preferences form in which logical fields are placed that indicate various bubblehelp that can be turned off--but only the ones that I have actually scripted to do this on each form, leaving the ones wanted to be permanent alone....and yes it can be a whole lot of extra script but all are so similar that it is not that hard to incorporate--just tedious. I also do this for warning dialogs--some to remain on and others that can be turned off by the user via the preferences form.

    I suppose Selwyn's script could be modified somewhat to accommodate this also...sort of like how you can leave some windows open when closing all the rest during a backup routine. Some crlf list perhaps of the fields wanted to still have the bubblehelp.

    Not as generic I guess as when you would simply use the function to turn off all the bubblehelp.

    Just thought I'd throw out the idea / exception.

    instead of using the onInit event to capture the existing bubble help into an array, you could eliminate the onInit event and then put the code that captures the existing bubble help in the function that turns off the bubble help.

    this means that every time you turn bubble help off, you first capture the existing bubble help to an array.

    it still works, with one change.
    the script that captures the bubble help needs to take into account that html bubble help can have crlf characters in it.

    so one small change is made to the onInit script that captures the bubble help.

    if you look at the form in the attached database, there is bubble help on firstname, lastname and company.

    here is the modified version of the script that captures the initial bubble help


    Code:
    function captureBubbleHelp as v (a as p, obj as p)
    dim controls as c 
    'need to take into account that bubble help can not include crlf. so this turns crlf into spaces.
    controls = obj.child_enum("r;e=this.name() + '|' + stritran(this.bubble_help,crlf(),' ')")
    controls = *for_each(x,word(x,1,"|"),controls)
    dim count as n 
    count = line_count(controls)
    a.resize(count)
    a.clear()
    dim i as n 
    for i = 1 to count 
    	a[i].name = word(controls,i,crlf())
    	a[i].bubble_help = obj.child(a[i].name).bubble_help
    next i 
    end function
