The Ulam conjecture is a popular task in IT teaching. This is an implementation in QB64.

A "problem" arises when the output is very long, because then the heading can no longer be read because the side scroll bars are missing.

I'll make a new thread.
I just read that there are new versions of QB64. Is there a special change compared to the versions from the old forum?

I'm using the latest version by the Old-Forum I think so: Version 2.02 from December 21, 2021.

Simple question. Has anyone written a slit-scan effect program for QB64? That is like the "trip" sequence in the movie "2001 a Space Oddity". If not, is anyone up to the challenge of making one? If so one little rule, it should use an external image to scan. Here is a short YouTube video that shows the technique. I can almost understand how to do it from that myself. Final thought - it might make a good screensaver project too.

Thanks.

A couple years ago I got this code from Felippe and made a cave shooter game with it as well as a gold hunting game. Today I decided to use Felippe's original example and add my own funny little game map to it. You use the arrow keys to move your guy around the map I drew. The map itself moves unless you are near an edge of the map. This is just an example but feel free to use any or all of the code as well as my map but please keep my "SierraKen" name on the bottom right corner of the map. I'm no artist as you can see, but I like it. Attached is the zip file called Map Movement Example.zip with the .bas and the .jpg files inside. Put both in the same directory. Tell me what you think, thanks.

Here's something I made to use for several things, thought I'd share it here.  It's a scrolling fog or cloud background you can easily add to programs.  The image is seamless so it looks like the fog/cloud just keeps rolling.  I threw in a flying witch to show how you can use it as a background with other things.

This uses a real image converted to bas code -  I'm trying to figure out how to make a good looking seamless fog image using just QB64 drawing commands instead, so I can eliminate using a real image (and a lot of BAS code).  Anyway, here's an example of scrolling an image as a background.

Just a small program for finding out what day of the week an event occurred/will occur on. Choose from Birthday, Western Christmas Day or any random day you choose. Unlike the other stuff I've posted on here to date, this is a fresh build. It Uses a tiny (edited) portion of the Time utility I posted recently. FWIW error trapping the INPUTs was a pain.

Here's a rehash of a little SUB I use when I have unpredictable sized, or aspect ratio'ed images to place in a predefined area. I call it Image_Resize. With the parameters, set a window area, identify source and destination, then set justifications (up, down, left, right, center). It does all the _PUTIMAGE figuring and then puts it, sized for best fit to the area.

A rehash because I originally posted it in the old forum, but I spruced up the example/demo code. Adding an image nesting and a swelling routine. The SUB itself has some of that cryptic looking branchless code, which was able to remove around 16 lines of SELECT CASE stuff, but I'm insufferably proud of that and haven't been able to break it yet.  

While it doesn't do rotations, there's always Rotozoom'ing to a temporary handle for that and I saw no reason to try and reinvent that wheel.

Some upcoming changes for the IDE help menu, which I wanted to point out for folks, that are coming soon(tm) to the Phoenix Edition.

   

The screenshot on the left is the old version; the version on the right is our upcoming alterations.  I won't waste time trying to spell out all the two changes in those two pictures, so I'll leave it to you guys to play a game of "What's different between these two images."  

Needless to say, I personally think the new version on the right looks a whole lot cleaner, neater, and more functional!   Three cheers for @RhoSigma for his work on pushing these changes into the language.  All the credit for the wiki/help update here goes completely to him! 

MemWave uses a Windows API call to play a WAV file loaded as a string.  This way you can include small sounds directly in BAS code and play them from string memory, not from an external file.  The example code posted will play a howling WAV sound.  I used BASFILE to convert the WAV file into string data here, but you can use whatever method you want - the main thing here is the way of calling the API.
