The revOpenDatabases function returns a list of all the currently open database connections, so it can be used to check if a connection is still open.

Kind regards

Hi As requested here is an example of a function that will work around the issue of losing a database connection, perhaps due to it timing out for some another reason. The basic idea is to use a function to return the database id when you need it, this function checks if the current connection is st...

Hi Jill A lot of this will be handled automatically for you by LiveCode. Attached is a sample stack, with no code. If you highlight some text in the list of fruits and drag it into the main text field it will be automatically pasted in where you drop it, without you having to do anything. If you hav...

Hi Here is a small stack showing how to change a background image based on a menu selection. The stack builds the path to the chosen image file, which it assumes is in a folder called "backgrounds" located next to the stack itself. It then appends the chosen image name to the folder and resets the f...

Hi As requested here is a very simple example of localiztion. The stack reads the file of transaltions into an array and allows the user to switch the selected language. The unicodeText property of a label field and unicodeLabel property of a button are used to display the text correctly. The string...

Hi As requested here is an example of how to filter the list displayed in a combo box. The full list is stored as a custom property of the combo box so it can be referred to as needed. As the user types the textChanged message is handled, the list is filtered using the filter command to find all the...

Hi Quentin

It does sound like the explicitVariables preference is on but if the last suggestion doesn't help please feel free to email me your stack and I'll take a look at it, elanor@runrev.com.

Hi I have put together a small template for an Android switch control. It uses a template group and a behavior so if you use it in any stacks you'll need to make sure the button containing the behavior script is part of your stack too. You can download the sample stack here . You create a switch by ...

Hi all I've done some experimentation and have found a way to resize MonGUI controls using the LiveCode Property Inspector, it's a little bit of a hack and if I come up with something better I'll let you know. The steps are - turn off "Disable auto geometry" in MobGUI - add a MobGUI control - open t...

Hi Quentin I think it might just be that you need quotation marks around your variable name e.g. put revDataFromQuery(comma, return, GetDatabaseID(), "pragma table_info(:1);", "tSelectedTable") into tColumnList I haven't set up a test so this may not work but syntax wise as least that's how it shoul...

Hi everyone

We've added a LiveCode Tips and Tricks document to the resources page.

Hi

It does look like you just need to update the version of MobGUI that you have, you can do this by clicking the Check for Updates button in MobGUI, second from the right in the top bar, looks like a refresh button.

The latest version is 0.29.

I hope that helps.

Kind regards

Hi EOTR

This is a really good suggestion, we will start adding links to additional resources to the document that accompanies the video each week.

Thanks for pointing out how useful this would be.

Kind regards

Hi EOTR Each type of MobGUI control responds differently to alt-double click, for example tab buttons get wider to fill the space, left buttons align themselves 10 pixels in from the left of the stack and buttons are horizontally centered. The MobGUI documentation explains how each control type resp...

Hi All Just a quick note as someone pointed out a small mistake in the video. At one point I set the SQLite option button to be the default meaning it is selected whenever you go to the card. Later I realised this was incorrect as if you go to Contact Details or Add Contact you want the option you l...
