I created a sub that has too many parameters but could fake the block graphic characters drawn by ancient computers such as the TRS-80 Model III. I have found a bug while composing this on Linux.

In QuickBASIC we could manipulate the time and date of the computer.

TIME$ = "06:30:00"
DATE$ = "10/20/2020"

I see QB64 currently supports only using those two statements to get the computer time and date, and no longer to set the time and date. Do we have a Windows API call that can manipulate the computer clocks available?

We had a discussion about using _CLIPBOARD to deliver info from one running QB64 app to another. Spriggsy brought up the point that method is frowned upon by M$, which recommends using a TCP/IP routine to pass the info.

So I decided to post a way to communicate back and forth between two QB64 programs.

Notes: You will probably need to tell Windows Defender to okay running these apps, as Defender checks for exe files of this nature.

How to use...

1) Copy/Paste the first program to your QB64 IDE.

2) Open a second IDE and copy/paste the second program.

3) Name and save the second program as; Pete2.bas.

4) Compile Pete2.bas or just run Pete2.bas and close it.

5) Go back to the first IDE, and select "Run" (You don't need to name this app. Untitled works just fine.)

What next? Well, the first program will SHELL open Pete.exe. Now you will have two windows opened. Click the first window, and INPUT 1, 2, or 3 at the prompt. After you hit Enter, you will see your choice appear in the second window as either A, B, C, or if you goofed up it will tell you. The second window sends a message back that it completed the task so the first window can loop back to the INPUT statement. Just close them out with the mouse when you are finished.

What does a mouse see? What does an elephant see? Perhaps the larger the animal, the higher it sees the world. The horizon increases with increasing altitude. What is huge for a small animal is small for a large animal. The small animal is slow compared to the ground, but normal speed compared to its own world. Although this is what the big animal feels, only the other way around. I wanted to convey the transition between the two perspectives.

Logically the answer to my question here is NO but embarrassment from asking stupid coding questions is my Forte.

When you have a loop control range, can you skip a specific step within the range? So for example the For Loop is 

For x = 50 to -50
   if x = 0 then next
Next

or if there may be a couple within the controlled range is there a way to

For x = 50 to -50
     if x = 10 or x = 0 or x = -10 then Next
Next

Thanks

Hi QB64 Fan Community

here a perfectable demo of a Vertical Scrolling List in ASCII mode

Mark asked about this, so I thought I whip up a little something to find out how many real line numbers are in a program. By real line numbers I'm talking about excluding spaces, but adding a line number count for the proper use of colons to separate statements on a single line.

I haven't goof proofed this yet, but I was hoping before going any further I could get some feedback or if anyone would like to modify it, etc. that's fine too. It might be fun for contests, etc. to have an "OFFICIAL" (ha ha) QB64 program line counter.

So basically it roots out trailing colons, REM statements with colons, both ' and REM, and any colons enclosed in quotes like PRINT statements. Did I miss anything? For instance, this routine counts...

CASE 1: PRINT "foo"

That colon is counted as an extra line.

CASE 1
     PRINT "foo"

If you think more conditions apply, it might be easy to add in the select case portion.

To try, just copy a forum post program or IDE program to the clipboard and run this code.

has anyone written a program that can process (and display) windows font files?
Thank you.

a simple example of using the clipboard to communicate between programs.

This example requires three programs Clipmaster ,cliptalk1, and cliptalk2.
Compile all three and save them in the same directory to see how this works. 

I almost certainly lifted the idea from somewhere else but I can't recall where, sorry if I'm failing to give proper credit.

Clipmaster

Back when I made the "tree house" game, a few years ago. It's 3D and you can only walk around. At that time, I remember Galleon rewrote the program and added something to the display part to shade the textures. Everything got darker in proportion to the distance. I didn't understand then. I looked for the code, but I couldn't find it, and the old forum is not available. Since then, I have solved the distance-proportional darkening of games by generating lots of textures. That's a lot of memory, and it doesn't work on a large surface, because if one vertex of a triangle is close to you and another vertex is far away, then what shade should it get? So it's only good for displaying small textures.

In the past few days, I've been thinking about how Galleon solved the problem of placing a texture of any size on the screen in any way. Then he told me that a black mask with an alpha distance proportional to the texture should be drawn. That's when I understood that by switching _depthbuffer on and off, it can be solved by dragging the alpha texture after each texture. And I understood why I didn't use it then. Very good, fast, practical, only switching the z-buffer on and off slows down the program significantly.

I was wondering how it could be solved without switching on the z-buffer.

Suppose _maptriangle gets a 3d point. be x,y,z. it should be 20,10,30. This point in the plane will be where, for example, 200,100,300 or 2,1,3 or 40,20,60. This simple realization helped. Simply, after drawing the texture, x,y,z must be multiplied by 0.999999, and then the mask can be drawn on it. That way, you don't have to switch on the z-buffer.
I thank Galleon several times already! If it doesn't show it then, I won't think about how it could be operated faster.
