This looks like it might work for me! I find myself needing to write an executible on my bosses desktop that he can click that will switch him between two different resoulutions.
example: if he is on 1280x1024 it will switch him to 1024x768 and viceversa.
Ill look around the fourms in a bit for the right code. maybe I just need to modify this. |

Thank you
Holger |

Could somome please review the code below as I get an error that EncodeInteger is already defined (not surprising) and I'm sure it can be simplified but I'm not sure how. FYI - I'm try to get it to swap refresh rates depending on which of the two progs I am running.
Thanks in advanace!

EncodeInteger() should be replaced with in-built NumPut()!
I hope you can adapt from the following code!
| Code: | cD = 32 ; bits (quality) - you can change to suit your requirments
sW = 1440 ; pixels - you can change to suit your requirments
sH = 900 ; pixels - you can change to suit your requirments
rR = 60 ; Hz (frequency) - you can change to suit your requirments
ChangeDisplaySettings( cD, sW, sH, rR )
Return
ChangeDisplaySettings( cD, sW, sH, rR ) {
VarSetCapacity(dM,156,0), NumPut(156,dM,36)
DllCall( "EnumDisplaySettings", UInt,0, UInt,-1, UInt,&dM ), NumPut(0x5c0000,dM,40)
NumPut(cD,dM,104), NumPut(sW,dM,108), NumPut(sH,dM,112), NumPut(rR,dM,120)
Return DllCall( "ChangeDisplaySettings", UInt,&dM, UInt,0 )
} |

here is some Win7 code related to this older great wrapper posted on this thread frm shimanov. it should be good with Vista since it based on similar principles
...someone may know how to translation each flag ChangeDisplaySettings are just from user32.dll!
note this is a C# wrapup
| Code: |
using System;
using System.Runtime.InteropServices;
namespace SwitchOrientation
{
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct DEVMODE
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
public string dmDeviceName;
public short dmSpecVersion;
public short dmDriverVersion;
public short dmSize;
public short dmDriverExtra;
public int dmFields;
public int dmPositionX;
public int dmPositionY;
public int dmDisplayOrientation;
public int dmDisplayFixedOutput;
public short dmColor;
public short dmDuplex;
public short dmYResolution;
public short dmTTOption;
public short dmCollate;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
public string dmFormName;
public short dmLogPixels;
public short dmBitsPerPel;
public int dmPelsWidth;
public int dmPelsHeight;
public int dmDisplayFlags;
public int dmDisplayFrequency;
public int dmICMMethod;
public int dmICMIntent;
public int dmMediaType;
public int dmDitherType;
public int dmReserved1;
public int dmReserved2;
public int dmPanningWidth;
public int dmPanningHeight;

How can I tell what resolution settings the user already has?
I want to write code that reads the colour depth if not 16bit then change to 16bit and run a external program, when program is finished change back to 32bit |
