Screen Resolution Problem 1

[tondi]

Our app is designed to run minimum 1024 resolution. We have a few users whose settings are set and verified at 1024 but our app still produces our error screen ststing we require 1024 minimum. Obviously VFP8 is not recognizing the setting. We even tried setting screen to 1280, still no luck. Any thoughts?

Are you using the sysmetric() function to test for the screen sizes?

The large/small fonts setting (or whatever it's called) in the screen properties may have an influence also.

Tondi,

Can you post the code you are using to determine the resolution?

Tondi,
I use the following, at virtually the beginning of my main code, to check for 800x600, you could obviously make a couple changes for 1024x768(??):

IF sysmetric(1) < 800 or sysmetric(2) < 600
	MESSAGEBOX("This program requires at least 800x600 resolution", 0+16+4096, "Please Note")
	RETURN
ENDIF

Note the "negative" logic, so you don't have to worry about ANDs, NOTs and/or ELSEs!

Rick,

Your code neatly solves the problem, but may I make a suggestion? I don't know how technical your users are, but if they are anything like some of mine, they probably don't know what a "resolution" is and have no idea how to change it. All they know is that your program has just issued a cryptic error message.

The message would be more useful if it also told the user how to change the resolution, and perhaps even offered to call up the display properties applet for them.

Just a thought.

I use almost exactly that the same as you.

Mike

How do you call the display properties applet??

Bob,

How do you call the display properties applet??

Use ShellExecute() to run DESK.CPL from your Windows System folder.

Thanks All for the replies and suggestions. I will forward this thread to my programmer. When I check the user's screen setting id DOES show 1024x768 which is what we need BUT for some reason our program is not recognizing the setting and returns our screen message stating minimum requirements 1024x768. This is only happening on a few of the many users we have sent the update to.

Here is the code we are using

CASE _SCREEN.WIDTH > 1000 AND _SCREEN.WIDTH < 1100 && 1024x768
DEFINE WINDOW MainWind FROM -1.5,0 TO 43.5,114 ;
FONT 'COURIER NEW',15;
ICON FILE 'SALONTEC.ICO' ;
NOCLOSE;
FLOAT;
NOGROW;
NOZOOM;
COLOR SCHEME 1


CASE _SCREEN.WIDTH > 1200 AND _SCREEN.WIDTH < 1300 && 1280x1024
DEFINE WINDOW MainWind FROM 0,0 TO 55,142 ;
FONT 'COURIER NEW',18;
ICON FILE 'SALONTEC.ICO' ;
NOCLOSE;
FLOAT;
NOGROW;
NOZOOM;
COLOR SCHEME 1

OTHERWISE
=MESSAGEBOX("Monitor Resolution must be: 1024x768 or 1280x1024",48,"Warning")
CANCEL

ENDCASE

Mike,
I agree with your user understanding comments - the code I borrowed was for a little utility program that we supply to "smart" customers. We have similar code for the "general" cumstomer that is much friendlier (dumbed down! ).

Tony,
I'd check the video card / driver that isn't apparently working. They may be using some non-standard setup that is reporting back what Windows thinks is true.
