ExecPageSetupDlg function (TLMDPrinter) fails in 64-bits

Christer Bergström

Am a happy user of SyntaxEdit for almost 10 years, and yesterday updated to the latest 2024 package! So I should have the latest version.

I've noticed however that ExecPageSetupDlg fails (crashes). This probably started already after update from Delphi 10 to Delphi 11 (using LMD2014), because it has worked previously.

It happens in my own project, but should be possible to reproduce with MegaDemo for SyntaxEdit:

1. Build pMegaDemo.dproj for Win64 and Delphi 12. 

2. Select "Page Setup" from the menu

3. The dialog is displayed briefly and then closes. There is an AV.

It crashes in some low-level code in LMDPagePaint.

Building for Win32 and running works OK. The page setup dialog pops up as it should.

I'm compiling with Delphi 12 (latest update 1), using Windows 10 Pro (10.0.19045).

Thankful for any advice! The preview and print functions look OK. 

Best regards

Hi,

Thanks for the report. The bug has been fixed.

Christer Bergström

Great, thanks!

How can I get access to the fix? 

Could not find any answer among your information documents, and the total source download seems to be the same as previously.

Best regards

As a workaround, if you can modify sources, the please find LMDPrintPageDialog.pas file, and in LMDPagePaint function change "cust" local variable type to NativeInt.

Officially changes will be available with the next minor release, which we create from time to time.
