Think of the keyboard buffer as a queue..

Indeed!
I've used: Just to make sure the keyboard buffer is EMPTY!

I did that very thing in a program I wrote in QB 3 about 6 years ago and ran under Win NT 4.

Also, you can use "DIRCMD= options" to force DIR into a particular format all the time. Then you can put that command in the AutoExec.Bat file.

It means you have an array and it has a certain dimension (the maximum number of elements in the array) and something in your program is trying to use or assign an element beyond or larger than that. For example: DIM x(25) y=x(27)=3 would generate such an error. Sometimes a misplaced parenthesis &qu...

You can still open the file in NotePad and print it from Windows.

I use It pops out of the loop when you press anything. Then you can test what was pressed. For example, if k$=chr$(27) then the Esc key was pressed.

I still use QB 3.0 and it has worked fine for me in every operating system that MicroSoft has put out including 3.1, 95, 98, NT3.5, NT4, 2000, and XP... I take that back. I have a QB 3.0 text program that writes to line 25. If I start the program from a shortcut and the program starts in a window, ...

In addition to Shell, you can also use the Chain statement, or the Run statement. Of course, this only works if you have the source for each program and you can modify and re-compile them. "Shell" will simply hold the current program in memory and allow the operating system to begin execut...

Qb is slow. OK, I suppose you could say that. I always assumed C/C++ was faster. I think it depends on a lot of things. I know most of you do graphics/game programming. Not me; I just crunch numbers, and folks, that's all done in the FPU. I saw an article in PC Magazine back in the 80's. The author ...

If you're looking for something just a tiny bit better than Paint, how about PhotoEd, the photo editor that comes with MS-Office? I believe the executable is Photoed.exe.

Are we talking about the typematic rate and delay here?

In DOS you use the MODE command to adjust that. In windows, there's a control panel item for that.

My son likes the GIMP.

I still use QB 3.0 and it has worked fine for me in every operating system that MicroSoft has put out including 3.1, 95, 98, NT3.5, NT4, 2000, and XP. I haven't tried it on ME. The computer I'm using now is XP and it works fine from a Command Prompt. Mind you, I'm not doing anything with the mouse, ...

...and here, I thought someone found a QB chess game... Nuts!

Oh, and... you can also do it with case structure like this: select case score case is < 500 ...do low score stuff case 500 to 1000 ...do medium score stuff case is > 1000 ...do high score stuff end select Also, if you use a "case" structure that can possibly have a "no case" cas...

I always write "less than or equal to" this way:
Either way works. I just think it looks better than =<.

Anybody know of a good Chess program written entirely in Q/Quick BASIC? I'm talking about something with AI, you know, the computer plays chess with a person...

My son has an interest in learning about vectors, matrices, projections, and such for BASIC game programming. This looks like the tutorial for him!

From about 1976 until 1995 I worked for a couple of different civil engineering firms. Part of my time was spent on software for civil engineers and surveyors, modifying existing, and writing new programs. My "pride and joy" is a coordinate geometry package for surveyors written entirely i...

In dos PrnScrn only worked if you loaded GRAPHICS.COM at the DOS start... In the VERY old days of DOS, PrtScrn worked without GRAPHICS.COM loaded, but that was back when CGA was the highest resolution (640x200). As QuickBASIC began to support higher resolutions, such as EGA (640x350) you needed to ...

Bought a 3-in-1 machine (printer, copier, scanner) for a family present. Hey! I'm finally with the 20th century! (Now, to get with the 21st!)
