Your Anti-Virus Software and Xojo

Published June 11, 2015 by Jason Parsley

UPDATE 12/2024

Though increasingly rare, we do still hear from Xojo users who get false positives from their anti-virus software when downloading Xojo or running Xojo applications. We’ve even heard of this occurring when users are debugging apps from the IDE. To get around this, you can refer to the documentation for your anti-virus software on how to exclude Xojo from scans. To fix these issues for yourself and future Xojo users, we ask that you report these occurrences to your anti-virus software makers.

We’ve occasionally heard from Xojo users that their anti-virus software gives them a warning about Xojo. All of these have been false positives and we ask that you report these to your virus software makers if it happens to you.

Casting about in both 32 and 64 bit worlds

Published June 8, 2015 by Norman Palardy

Consider the following code:

dim i64 as Int64 = 1234567
dim i32 as int32 = 7654321

i32 = Int32(i64) // cast
i64 = Int64(i32) // cast

i32 = Ctype(i64, Int32) // convert
i64 = Ctype(i32, Int64) // convert

It all seems reasonable enough. Not useful, but seems reasonable. Only one problem. It won’t compile. Why not? The two casts to int32 and int64 will fail. Now why is that?

Private/Public Key Interoperability

Published June 1, 2015 by Xojo

If you do any work with private/public key cryptography, the addition of the Crypto library last year made it finally possible to create and verify digital signatures as well as encrypt and decrypt data. Using keys with other systems requires a little more work to convert them to and from the PEM format.

What is Raspberry Pi?

Published May 14, 2015 by Paul Lefebvre

The announcement at XDC 2015 of upcoming Xojo support for Raspberry Pi was greeted with enthusiastic applause. But after the keynote, I had several people come up to me and admit that they did not know what this Raspberry Pi is, so I thought I’d take a moment to give some background.

Preparing for a 64-bit World

Published May 8, 2015 by Paul Lefebvre

Xojo already creates 64-bit apps for iOS. Soon, it will also create 64-bit apps for other platforms. I, for one, welcome our new 64-bit Overlords. After all, they’ll be bringing you increased performance and increased memory! Even better, there is not much you’ll have to do to create 64-bit versions of your existing Xojo apps.

UPDATE October 2015: Xojo Builds 64-bit Apps Now
