  Could someone explain these references I keep seeing to compiling with "-O2"?
Posted by: hanness - 06-09-2022, 08:50 PM - Forum: General Discussion - Replies (4)

I'm not clear what these optimizations do. Could someone give me a basic explanation of what this is?

If I want to try this in 0.8.0, do I simply plug that into Options > C++ Compiler Settings > C++ Compiler Flags?

Are there any negatives to using this flag that I should be aware of?

  Announcing QB64 Phoenix Edition v0.8.0 Release!
Posted by: DSMan195276 - 06-08-2022, 07:26 PM - Forum: Announcements - Replies (14)

QB64 Phoenix Edition v0.8.0!

New Features
  - A new 'C++ Compiler Settings' dialog, under the 'Options' menu. It allows setting:
    - Compiling program with C++ optimizations using

-O2
(off by default).
    - Strip symbols from executable (on by default)
    - Add C++ debug information to executable (off by default)
    - Textbox for supplying extra compiler flags
    - Textbox for supplying extra linker flags
    - Entry to modify the maximum number of C++ compiler processes to run (setting this higher can speed up compilation).

Bug fixes
  - Many improvements to the rendering of the Wiki in the QB64 IDE.
  - Improved dialog text around missing
curl.exe
  - The IDE will not attempt to keep downloading help pages if
curl.exe
is missing.

  "Locate" in the program
Posted by: Kernelpanic - 06-07-2022, 08:04 PM - Forum: General Discussion - Replies (40)

Hello, is there a way to set the distance from the edge for the whole program with "Locate"?

So far I've only found the way, see screenshot. Pretty laborious. Thanks!

  0.71 Info on compilation error

I attach the report of the failed compilation that I obtained.

With version 0.6, however, there were no errors.

Thank You

  idea - a "Rosetta Code" of classic games?
Posted by: madscijr - 06-07-2022, 11:25 AM - Forum: General Discussion - No Replies

What could be interesting and cool would be a sub-wiki or thread dedicated to simply compiling links (+source code) to versions of every classic game done in QB64 (or a link to source code for any done in another language). This might help beginning programmers looking to recreate a certain game or learn.

  Is there a way to delete the Alt+PrtScr image from Windows?
Posted by: Pete - 06-06-2022, 10:18 PM - Forum: Help Me! - Replies (2)

For instance, with _CLIPBOARD$ you just use: _CLIPBOARD$ = "" but not so with _CLIPBOARDIMAGE. For example, _CLIPBOARDIMAGE = 0 doesn't clear it, it just takes a snap shot of the current window. What I was looking for is a way to use Alt + PrtScr to copy the active window to the clipboard, save it to a file, and then remove it from the Windows clipboard.

Without being able to remove it from the Windows clipboard so I can poll for the next Alt + PrtScr instance, I need the extra

click back on the Qb64 app step, as seen in the example code, below. Caution, it will add a file to your local directory labeled as: screenshot(1).bmp.

To try it out...

1) Run the app.
2) Click the window you want to screen shot to make it active.
3) Press Alt + PrtScr
4) Click in the window of the Qb64 app.
5) Look for the screenshot in your local folder.

Code: (Select All)
REM This utility will make store screen shots in the local directory.
SCREEN _NEWIMAGE(370, 90, 32)
_SCREENMOVE 0, 0

DO
    CLS
    PRINT " Alt+PrtScr on active window then clcik here."

    DO
        _LIMIT 30
        WHILE _MOUSEINPUT: WEND

        IF INKEY$ = CHR$(27) THEN SYSTEM

            IF _FILEEXISTS("screenshot(" + num$ + ").bmp") = 0 THEN EXIT DO

        SaveImage img&, screenshot$

        IF img& < -1 THEN _FREEIMAGE img&

        DO

            IF _FILEEXISTS("screenshot(" + num$ + ").bmp") THEN
                PRINT: PRINT " Image saved..."
                _DELAY 1
                EXIT DO

  the apocalypse!
Posted by: krovit - 06-06-2022, 08:45 PM - Forum: General Discussion - Replies (20)

Hi!!

We all worried when there was the change at the top of QB64 and the reassurances were not enough to dispel the doubts...

I'm definitely off topic but try to understand me... I don't know anything about what happened and I can't orient myself... it's gone (almost) everything... and qb64 looks dead (for sure he is dying).

QB64 Phoenix is a fork of QB64... ?

In addition to all this there is also the fact of the language (I do not speak English) which makes everything more difficult

Years of development in QB64 destined to die... is it possible that this is destiny?

Tell me something please and inform me about the situation...

Thank you!

------
I read the presentation of SMcNeill but you know and give for obvious a bunch of things that I do not know.
And if qb64 phonex is a "clone" of qb64 as compatible with the original?

Someone has access to the old forum threads ?  In need to monitor some raspberry pi's on my home network using ping.  I know the old forum had some before it all got nuked.  Some very good examples and code.  I should have saved a couple (my bad).

If someone saved the old forum (pre-nuking) please provide a URL.

  DavsIDE - Alternative IDE for the QB64 compiler
Posted by: Dav - 06-06-2022, 02:07 AM - Forum: Dav - Replies (24)

DavsIDE is an alternative IDE to use with QB64.  I started this back in 2010, when QB64's IDE was still very slow to use.   However, the QB64 IDE today is FAR better than back in 2010 , making my IDE almost useless now.  Although DavsIDE is no longer being actively developed, I will update it from time to time to correct bugs and to thank the people that have supported it over the years.  It has a read me file (DavsIDE.txt) so read that for more information on how to use the IDE.

  BUG? Compile errors with filenames that contain $ in them.
Posted by: Dav - 06-05-2022, 04:09 PM - Forum: General Discussion - Replies (3)

Working with an error in my QB64 IDE, with the help of RNBW, (posted about here) it was discovered the latest version of QB64 won't compile correctly when the .BAS filename has an $ in it.  Previous QB64 versions did compile them, but not v0.6 and newer.

Example, save a file with $ in it, like Money$.bas, it will have a compile error.  Without the $ it will compile.
