I'm so close to having everything working - just a few tiny odds and ends to figure out....

Let's say I open a Windows a screen with QB64 that is 400 x 400 pixels and I start displaying text on the screen with a font size of 12. My calculations say that I should be able to fit 33 lines of text on this screen (33 x 12 pixels = 396 pixels). However, in actuality, I can only fit 32 lines.

Is there something like an invisible "buffer" of a few pixels that cannot be used?

When I use a screen capture utility to capture a copy of my window, I can see that the area inside of the physical screen borders is precisely 400 pixels so I can't quite make sense of what I'm running into.

That's weird. I go away for a little while and come back to find there's nothing to come back to. After a quick Google I find this site. I must remember not to go away again 

I suppose with Phillipe out then there'll be no more 'InForm'? 

Hey everyone.

A while ago I asked about setting up Notepad++ to compile/debug QB64 code, and TempodiBasic graciously provided some instructions which I finally got around to trying out, only it's not (fully) working.

I'm running Windows 10 Pro with QB64 2.0.2, and Notepad++ which self-updated to v8.3.3 today and works fine. 
Per the instructions, I installed the NppExec plugin, and added the QB64 folder to the system path, and rebooted.

I have a "hello world" program in my qb64 folder, e.g.

• C:\Users\{username}\Documents\Code\qb64\programs\hello1.bas
  

Some years ago I wrote a tutorial on this topic for the scripting community of Neverwinter Nights. I have now gone through this and edited it to make it relevant for QB64. As I am new to QB64, I would appreciate it if someone will download it, read it and let me know of any errors that they come across no matter how small. The package contains 2 pdf documents (the readme and the 20 page tutorial), an HTML cheat sheet and a plain text document of pre-calculated constants.

All comments welcome.

Thanks.

I posted earlier about an issue involving font sizes on a screen. I've figured out how I can perform manual calculations, but I need to know the screen scaling factor to make my calculations.

Is there some way that I can ascertain the scaling factor from within QB64?

A simple little image unroller that does an image reveal like a scroll being unrolled. Someone posted an example in a facebook group in their dialect of basic asking if other forms of basic could handle it. So I whipped this up. 

Assume that I am initializing my display like this:

        _FullScreen _Off , _Smooth
        _FreeImage oldimage&
        Font& = _LoadFont(FontPath$, FontSize, "MONOSPACE")
        _Font Font&

Now I write a bunch of text to the screen.

Later, I want to read the character at the upper left of the screen. I tried to do this like this:

print screen(1,1)

or

MyVar$ = CHR$(screen(1,1))

However, I'm getting an illegal function call when the line with screen(1,1) is executed.

Is this only valid with screen mode 0 or am I missing something here?

If this cannot be made to work, is there any other way to read characters from the screen?

Attached is a QB64 program just to say thanks to Steve for quickly putting up this QB64 forum for us all.

Is there a list of QB64 constants, like _PI=3.14..?
Also, 1/0 gives INF and -1/0 gives -INF.  Are there INF and -INF constants?
This code is just some experimenting (some garbage in the 2nd line of output - no problem).
