System info plays very important role in adjustments of your project to work on various end-user machines; depending on retrieved info, your project will be able to select most suitable presentation for current machine. In MMB, system constants hold screen, window, processor and memory info and these constants are used as parameters for script commands.
For example:
ScriptCommand(SystemConstant(),Param2)
Script command will use system constant as it's first parameter. See descriptions of real script commands to find out which ones can accept this kind of parameters.
ScreenWidth()
returns width of computer display in pixels as an integer value
Script example:
Message("Display width is: ","ScreenWidth()") |
ScreenHeight()
returns height of computer display in pixels as an integer value
Script example:
Message("Display height is: ","ScreenHeight()") |
WorkAreaWidth()
returns width of computer display work area in pixels as an integer value
Script example:
Message("Display work area width is: ","WorkAreaWidth()") |
WorkAreaHeight()
returns height of computer display work area in pixels as an integer value
Script example:
Message("Display work area height is: ","WorkAreaHeight()") |
MouseX()
returns X (horizontal) screen position of mouse in pixels as an integer value
Script example:
Message("Current mouse X position: ","MouseX()") |
MouseY()
returns Y (vertical) screen position of mouse in pixels as an integer value
Script example:
Message("Current mouse Y position: ","MouseY()") |
MouseLButton()
MouseRButton()
MouseMButton()
returns a state of mouse buttons.
If mouse button is pressed then return value is 1 otherwise 0.
Script example:
To Page Start code insert ScriptTimer, which will start a global MouseState detection script
ScriptTimer("Timer1=Script","50")
Create new script object called Script and insert the below code into it:
MStateL=MouseLButton() MStateM=MouseMButton() MStateR=MouseRButton() MState=MStateL+MStateM+MStateR ** one button is clicked If (MState=1) Then If (MStateR=1) Then LoadText("Text","RIGHT CLICK IS DETECTED") End If (MStateL=1) Then LoadText("Text","LEFT CLICK IS DETECTED") End If (MStateM=1) Then LoadText("Text","MIDDLE CLICK IS DETECTED") End ScriptTimer("Timer1=click","50") Return() Else ** none or more than one button is clicked LoadText("Text"," ") End ** restart mouse detection script ScriptTimer("Timer1=click","50") |
For more advanced example of mouse state detection procedure check the mousestatedetection.mbd example project.
WinVer()
returns major, minor and build version of running Windows as string (text) value
These values are separated with dot . so use MMB's advanced string functions to extract individual version values. |
Script example:
var$=WinVer() Message("Windows version : ","var$") |
Returned value will be for e.g:
5.01.2600
Windows have somewhat standardized version numbers. Here's a list:
|
UsingWinNT()
returns integer (number) value having one of two available states:
1 = machine runs WinNT-family operating system 0 = machine doesn't run WinNT-family operating system |
Script example:
Message("WinNT-compatible OS present: ","UsingWinNT()") |
If WinNT family OS is present, returned value will be:
1
ScreenColors()
returns number of colors currently being used by Windows & graphics card
Value returned is integer (number) and represents number of colors (16,256) for lower modes or number of bits (16, 32) for higher graphic modes. |
Script example:
Message("Current graphics color mode: ","ScreenColors()") |
Returned value will be for e.g:
32
ProcType()
returns manufacturer, type and speed of central processor unit (CPU) as string (text) value
Script example:
var$=ProcType() Message("CPU in this machine is: ","var$") |
Returned value will be for e.g:
Intel (R) Pentium (R) 4 CPU 2.40 GHz
ProcFreq()
returns speed of central processor unit (CPU) in MHz as an integer (number) value
Script example:
Message("CPU frequency in MHz: ","ProcFreq()") |
Returned value will be for e.g:
2405
GetMemory()
returns quantity of Total and Free RAM memory as string (text) values.
These values are separated using slash / character, so use MMB's advanced string functions to extract individual memory values. |
Script example:
Message("Machine memory status: ","GetMemory()") |
Returned value will be for e.g:
512/231
(first value represents Total Memory, second Free Memory)
