Hello,

I have downloaded the trial ver. and was thinking of purchasing DBpro. I have downloaded many demos and there seems to be 1 thing in common with all of them. Whenever text is used it is always flickering. I am assuming this was b/c the author wanted the text to remain on the screen so he/she put it in one of their main loops.

I was just wondering am I the only one experiencing this? If not is there a way to reduce/remove this?

Thanks

I've never noticed this in any DB or DBP program, it could very well be your computer.

Putting sync where you want the screen to update may work, ie. before the cls and after the text has been printed. You will have to put a sync on at the beginning of your code to enable manual screen refresh, eg.

Weird, the snippet you gave me still flickers like a mother. Printing out the text once looks normal, but as soon as it starts to loop, the text flashes (mind you the flash is quick but QUITE noticable)

Here are my specs:

PIII ~935 MHz
512 Ram
NVIDIA GeForce4 MX 420 @ 1024 x 768 (32 bit)
Windows XP Professional

Any ideas??

I've got the same text flickering problem. At least with that little code snippet up there. Had other text problems in other areas as well.

Might be due to having the same video card.

A simple..

do
cls
print "hello"

loop

Works fine though.

If I put the CLS before hello, you get a permanent hello. Put it after, you get a blank screen.

Put in that 'sync'. Flicker.

I don't think there is anything wrong with your PCs or your video cards guys

The ideal way to layout that snippet is to have Cls at the top and Sync at the bottom with something in between:
