I remember now why I gave up; the MS controls don't let you get an array of character codes or anything, since they pass back a Unicode string. Unfortunately Labview downcasts this so you can't use it, although frsutatingly you can paste Unicode text into it and it displays correctly. You can't even get the value as a variant from one text box and feed it into another. The only way I can see to do this is to make a new textbox ActiveX component in .NET inherited from the standard one and with a couple of extra members to allow getting and setting the text via arrays of integers to represent the characters. Doable if you really have to, and not really that much hassle since you won't have to do all the autosize stuff as was necessary when doing this kind of thing with VB6. Unfortunately, I've had a tinker for a few minutes and I can't see how to do this with .NET! You can no longer make ActiveX controls in VB; instead you can make either a "Windows Control Library" or a class library. Both of those can inherit from the text box, both make assemblies that can be found and referenced from Labview 7, but neither produces anything that can go into an ActiveX container and I can't figure out how (if it's even possible) to instantiate the control and make it appear on the panel at run time. Which is a bit odd- it's a step backward not being able to do controls in Visual Studio any more for use in Labview! Both of these entities can be used as controls in other .NET projects, but that doesn't help a great deal. In VB6 you can do it, but since it lacks inheritance you have to manually wrap all the properties of the textbox that you're likely to need, and you'll have to make your own resize code. Very tedious, but it is an option if you have VB6 floating around- I don't think you can buy it any more. -- Dr. Craig Graham, Software Engineer Advanced Analysis and Integration Limited, UK. http://www.aail.co.uk/
