Hi,
I'm using the Borland Builder 5 for my bachelorthesis and writing in C++. I want show some Data on a big screen. I tried to show the Data with a memo, label or edit-field, I tried Calibri and Cambria fonts. If I use a fontsize> 80 Data flickers non-periodic. If the size is 80 or smaller its all fine.
I'm uptdating the data every 50ms.
Does anyone has a hint to fix it or can explain this effect to me?
I would like to use a fontsize around 120 to 140.

thanks
pasqual

What kind of thesis are you writing using 17 year old software?

Flicker usually occurs when you force repeating repaints when you
shouldnt be. Please show your actual code, you are likely doing
something wrong with it. This is not a font issue.

Pasqual is using the 17-year old TObject software, just as you are, Remy.

Builder 5 is still an excellent Windows application-building product, with very few limitations. Personally, I develop faster with the 17-year old IDE than with XE 10.x. I have earned 100 times the money with Builder 5, over XE. On the other hand, have wasted days debugging parts of XE, for instance, the fatally flawed seh_handler for x64. XE is/has been bugged, nearly to death. quality.embarcadero.com is replete with the shortcomings of various parts of XE. If you enjoy being thrown under the bus, purchase a XE license and let the complaints begin.

Pasqual, do not be baited by any part of XE. You will be days, weeks ahead, sticking with C++ Builder 5. Just go to the used book store and obtain the common books written just for C++ Builder 5. Meanwhile, where are all the XE books? 0 none nada.

TObject, are you any higher performance now, than you were 17 years ago?

No. Same source code, same object code pumped out by the practically same compilers.

Pasquale, keep your Builder 5 close. It is your friend.
