Firemonkey: TLabel text truncated despite autosize property true

may help you . After tinkering around with a bunch of settings both in XE8 and on Windows I finally found the solution. The machine running Windows Server 2008 R2 had all of its visual enhancement settings turned off which caused the application to render in correctly.
The specific setting which needed to be enabled was "Use Visual Styles on Windows and Buttons". It appears this setting has to do with Aero as it is not available on my Windows 8.1 machine.

Firemonkey: Setting TLabel Text causes String Index out of Range Exception

Firemonkey: Setting TLabel Text causes String Index out of Range Exception

around this issue Currently updating to new new C++ Builder so cant play around with your snippet. I have method's for handling error messages which are output to a log tab as opposed to the ShowMessage, rather than using a string though I use a TStringList. For example:
code :
void __fastcall TPasswordChangeForm::BuildHelpMessage()
{
    TStringList HelpMsg = new TStringList(this);

    if( NewPassEdit->Text.Length() < MinPasswordLength )
    {
        HelpMsg->Add("Password length too short.");
    }
    else
    {
        HelpMsg->Add("Password length OK.");
    }

    if( NewPassEdit->Text == ConfirmPassEdit->Text )
    {
        HelpMsg->Add("Passwords match.");
    }
    else
    {
        HelpMsg->Add("Passwords do not match."_;
    }

    ShowMessage(HelpMsg->Text); //added for debugging, shows string as expected

    HelpLabel->Text = HelpMsg->Text;  //exception thrown here
}

Hope that helps The following code is taken from code that works in an FMX application, modified slightly to remove arrays that are being iterated through and declaring a variable locally to the function. It is being run in a TForm method. Canvas here is the Form's Canvas. You can see that I'm using "- 35" at one point - this might be because the numbers weren't quite right.
code :
double InitialFontSize = 30;    
Canvas->Font->Size = InitialFontSize;
StoryHeadlineLabel->Font->Size = InitialFontSize;
bool fits = false;
do
{
    double widthA = Canvas->TextWidth (StoryHeadlineLabel->Text);
    if (widthA > StoryHeadlineLabel->Width - 35)
    {
        StoryHeadlineLabel->Font->Size --;
        Canvas->Font->Size --;
    }
    else
        fits = true;
    if (StoryHeadlineLabel->Font->Size < 6)
        fits = true;
} while (!fits);

wish help you to fix your issue If we set HitTest to True, this control captures all mouse OnClick and OnDblClick events.
If we set HitTest to False, these two mouse-click events will pass through this control, so that a control laid out behind this one receives the mouse events instead of this control.

I wish this help you In VB.net, Visual Studio 2019, I am looking to make a Masked Text Box height taller than the AutoSize allows me to, so I use the code: , Try using your own that pre-sets the property for you:
code :
Public Class MaskedTextBoxEx
  Inherits MaskedTextBox

  Public Sub New()
    Me.AutoSize = False
  End Sub
End Class

hop of those help? I managed to get Xcode (running as a VM under Windows) pushing an XE2 build FireMonkey iOS HD app to my (jailbroken) iPhone after XE-script-prep (creating the Xcode folder), with a valid company certificate. , This works fine for me.
