Hi guys,

I'm trying to reference the contents of a variable using its name in another variable. So far its not working. Any pointers? Here is an example of what I mean.

put "x,y,z" into var1
put "var1" into varibleName
put item 1 of varibleName


What I get in the message box is var1 but what I ...

When I use

replace oldWord with newWord in field "textField"

every instance of oldWord is replaced by newWord. How do I replace just one specific instance -- for example the clickText?

Hi Preston ~

Try putting this in a locked "textField":

put newWord into the clickChunk

Sorry to be a bubble buster, but that hasn't been my experience.. however I am going the opposite direction. I develop on a Mac and deploy to both Mac and Windows but I always have problems getting my Windows versions to work and appear correctly. Macs are more forgiving I think, especially in the ...

Hi Smash ~

There are several ways to do this, but one way is to add the line:

delete the first char of field "Credit"

This will remove the first character of the field "Credit" which is the minus sign.
One minor point though... it's standard accounting practice to have the minus sign in front ...

Hi Jim ~

It may be something in the standalone settings that is incorrect. Maybe check some of these things out in the Standalone Settings under the File menu...

Under the "OS X" icon...
Is the end user you sent the zipped standalone using an Intel or PowerPC Mac? Did you check "Build For ...

Hi again Phil,

I obviously didn't have enough coffee yet this morning because I missed the line in your original post which said "It also throws an error if I use the integer test that works on SQLite and MySQL."
So you're saying you still get your error line: "Could not connect to database:" even ...

Hi Phil,

I'm no expert, but I believe the revOpenDatabase returns an integer which is an ID to the database, and your current code is checking for "true", a boolean. If revOpenDatabase fails, it returns an error which isn't an integer, so you can check the connection by verifying the return as an ...

Using Rev for creating forms only to be filled in by hand seems like overkill to me, and the wrong tool for the job.
Why not just set up the form using something like MS Word? Much faster and it's WYSIWYG.
Unless you are going to fill in the form via a Rev app interface, it seems a waste of time ...

What does "double binary operator" mean?
The word "is" in Rev is a synonym for "=" allowing you to use English in an expression such as:
if x is 34 then
or
if x = 34 then
so you got a "double binary operator" error from Rev because you're expression:
if whatCase is >= 65 then put whatCase into ...

...I'd be interested to learn the command to reset all the text boxes to blank based on a mouseup event

Hi Clint ~
I'd just add to Jan's excellent advise...
If you wish a field to be "blank" and have no text or numbers in it, you can also use the Rev constant "empty", for example:
put empty into ...

Hi,

I've copied a web page (archive) to my desktop and I put it in the same file as the program I've written with Rev. I have a button in the program that I want to open this archive (web page). I have my Airport (wireless) shut off because I want to show how I can open a web page and there may ...

Some final thoughts...

You may want to use Apple's Console app (in your Utilities folder) and have a look at system.log to check for any clues on boot up. You may glean some insight there as to what may be happening, and for some background and perspective on any suspicious entries in the system ...

The only other thing I can think of right now is to run one of the system maintenance utilities (checks system preference files and cleans out corrupt cache files, etc).

Here are some to check out:

There are a few more things you could try before concluding it's a hardware problem.

1. It appears you have a black desktop. What happens if you change the desktop to any of the Apple provided ones in System Preferences->Desktop & Screen Saver?

2. Use Apple's Disk Utility to Repair Permissions.

Hi Bill ~
You can set the: bottomMargin, topMargin, leftMargin and rightMargin in pixels, to move the button text right where you wish as:
