For those that may be searching for this in the future: You need to assemble a URL and display it as a QR code so it can be scanned by an authenticator application. The format is given here: https://github.com/google/google-authenticator/wiki/Key-Uri-Format I use this string and substitue in my values. otpauth://totp/[COMPANY]:[ACCOUNT]?secret=[SECRET]&issuer=[ISSUER]&algorithm=[ALGO]&digits=[DIGITS]&period=[PERIOD] You then display it as a QR code for the user to add to their authenticator application. I found that whatever time period I entered into the URL(30sec, 60sec etc), the authenticator applications always defaulted to 30 seconds. This means your TOTP checking code also needs to use a 30s window.

Thanks for that. I've added OTP support already, but wish to add the use of authenticator apps like MS/Google Authenticator but there's not a lot of info out there.

Hello Has anyone added MFA support using authenticator apps for their application? Any resources greatly received. Thanks D

Hello Roger We have a copy of RADStudio so it was an easy job to compile any Delphi components. For the components where we have the source (Delphi or C++), we needed to add an additional 'Target Platform' of 'Windows 64-Bit (Modern) '. Using the macro $(Platform) in the output path will create a \Win64x output directory. For those Delphi components for which we do not have source code, we'll just have to wait for an update from the vendors.

The answer requires all Delphi components to also be compiled with the 64-bit Modern compiler (usually to a 64x directory)

When testing BCB v12.2 I place one third-party component on a form and compile for 32-bit and 64-bit with no issues. When compling with the 64-Bit (Modern) compiler I receive the following error: [ld.lld Error] ld.lld: error: unknown file type: HTMLabel.o Do Delphi 3rd-party components need any special compilation to work with the 64-bit (Modern) compiler?

Both 11.3 and 12.1 have that 'else' in place and both enforce the MinWidth setting. It is possible to drag to a smaller width than MinWidth but upon release it springs to MinWidth width. I'm now wondering if I was just fixating on the dragging and not when the mouse was released.

I submitted this as a bug and they could not reproduce it in 11.3. Now, neither can I. I can reduce the column width to below MinWidth but as soon as I release the mouse button it springs back to MinWidth. I'm starting to doubt my sanity.

Thanks. I'm using CB 11.3 In the interim I thought I'd detect the column widths changing and then enforce the min width, but there doesn't appear to be any event that fires when a colmn has changed size. Never mind, found a solution you wrote in 2012.

Hello I'm using a TListView in Report mode and I'm creating columns dynamically. I am setting TListItem.MinWidth = 50, but when ran, this is being ignored. What am I missing? Thanks David

We're currently using v11.3 and at the time of v12 release I didn't really see anything compelling enough to update (we're on a subscription) and go through the agro of updating all our third-party components. Is there a noticeable difference?

Thanks. Any idea on the lifetime of a connection/use for a code signing cert?

Why is that? Can multiple remote PCs connect to the Virtualhere server?

Thanks Lars. Running C++ Builder 11.3 for any other that's have tackled this issue.

I'm having difficulty saving and restoring column sizes when the user has their Windows Scale and Layout Scale value set to 125% (i.e larger fonts). With 100% font scaling, I can set and save the column widths without issue. If I set a column at 100pix and the user does not change the width, then it will still be 100pix when I save the column widths. With 125% font scaling, setting the column widths at 100, will result in a width of 125 when it comes to saving the column width. Using the Form's GetPixelsPerInch function I can save the 'base' width value. The issue I'm having is that adding an Image to the column header to denote that the list view is sorted using that column also appears to add in a further offset when it's time to save the column widths. This is only the case with non-100% font scaling. Has anyone handled this to obtain the base width without scale or image offsets?
