Hello!

How do I disable the middle button of the three buttons on the top right corner, so the user can not maximize the window, but minimize and exit it?

The following will deactivate the maximize button:

set window on

set window title "Deactivate Maximize Button"

rem variables and constants

user32=1

GWL_STYLE = (-16)

WS_MAXIMIZEBOX = 65536

WS_MINIMIZEBOX = 131072

load dll "user32.dll",user32

rem query window handle

hwnd=call dll(user32,"GetActiveWindow")

rem get the current window style - this has min max info

curstyle=call dll(user32,"GetWindowLongA",hwnd,GWL_STYLE)

rem this is just a test to see if MAXIMIZEBOX is included in the current style

print curstyle & WS_MAXIMIZEBOX

rem should be able to adjust the style by subtracting the max button from the

rem current style

newstyle=curstyle-WS_MAXIMIZEBOX

rem write the new style to the window

result=call dll(user32,"SetWindowLongA",hwnd,GWL_STYLE,newstyle)

print result

rem get the current window style - this has min max info

curstyle=call dll(user32,"GetWindowLongA",hwnd,GWL_STYLE)

rem this is just a test to see if MAXIMIZEBOX is included in the current style

print curstyle & WS_MAXIMIZEBOX

+ Code Snippet

set window on

set window title "Deactivate Maximize Button"

rem variables and constants

user32=1

GWL_STYLE = (-16)

WS_MAXIMIZEBOX = 65536

WS_MINIMIZEBOX = 131072

load dll "user32.dll",user32

rem query window handle

hwnd=call dll(user32,"GetActiveWindow")

rem get the current window style - this has min max info

curstyle=call dll(user32,"GetWindowLongA",hwnd,GWL_STYLE)

rem this is just a test to see if MAXIMIZEBOX is included in the current style

Isn't there a SET WINDOW thing that lets you hide the buttons?

Are you running the Lite version of DB? DB Lite is not compatible with the enhancement pack (See DB Lite info).

This might mean that DLLs cannot be loaded and as a result cause a fatal error. Can anyone confirm this to be true?

It's an all or nothing command in DBC - set window layout - you can't pick and choose individual buttons.

Quote: "Hey latch. how do you make it so the button is grayed? cuz right now it just doesn't work."

Did you try clicking on the maximize button? It will not let you maximize the screen and then grey out. In order to see the button become grey the window has to be refreshed with the new settings in place.

So, add this command to the end:

RESTORE WINDOW

and the max button will appear grey.

set window on

set window title "Deactivate Maximize Button"

rem variables and constants

user32=1

GWL_STYLE = (-16)

WS_MAXIMIZEBOX = 65536

WS_MINIMIZEBOX = 131072

load dll "user32.dll",user32

rem query window handle

hwnd=call dll(user32,"GetActiveWindow")

rem get the current window style - this has min max info

curstyle=call dll(user32,"GetWindowLongA",hwnd,GWL_STYLE)

rem this is just a test to see if MAXIMIZEBOX is included in the current style

print curstyle & WS_MAXIMIZEBOX

rem should be able to adjust the style by subtracting the max button from the

rem current style

newstyle=curstyle-WS_MAXIMIZEBOX

rem write the new style to the window

result=call dll(user32,"SetWindowLongA",hwnd,GWL_STYLE,newstyle)

print result

rem get the current window style - this has min max info

curstyle=call dll(user32,"GetWindowLongA",hwnd,GWL_STYLE)

rem this is just a test to see if MAXIMIZEBOX is included in the current style

print curstyle & WS_MAXIMIZEBOX

That's very strange. Anyone else having that problem?

What version of DB are you using, and what version of windows? And are you using DarkEdit or the default black screen editor? I noticed my code vanishes when I use the db editor, but if I move thslider on the side, it all reappears.

Try typing this at the top of a new DB program as the only command

SET WINDOW ON

and press F5

It should open the CLI in windowed mode.

Now type one line at a time from the above program pressing ENTER after each line in the CLI.

You'll know which line is causing the problem after you type it and press enter. Make sure you've saved anything you want to keep in case the bad behaviour returns.

Enjoy your day.

Do you have a trial version of DB or something? The SET WINDOW ON command shouldn't cause trouble.

And using SET DISPLAY MODE, you should be able to set any display that your graphics card and monitor can handle.

Enjoy your day.

I guess I have a terrible graphics card because i can't do 32bits

or almost any other displaye modes.I think I could get a better

graphic card from school they have a bunch of computers they are

thinking of just trashing.

no, I have the full version of db v1.12

I see. Here, try this screen display mode selector that was written by TDK_Man a few years ago . Though we're getting off topic a bit, you should be able to see all the available scree n modes and be able to click and select one:

It worked perfectly for me, thanks Latch!

And while we are at windows, how can I make it that if the window is minimized or behind other windows that it doesn't take up 100% CPU usage?

The ideal environment for DarkBASIC Classic! If you have an old machine around, try it out. You'll be amazed at the performance of DB without having to implement any work arounds.

For the 100% CPU cap, I think Benjamin came up with the kernel sleeping method and Robert The Robot tested out different scenarios and put together a nice complete solution for DBC use.
