Inno Setup的[Code]部分变量为[Registry] [英] Inno Setup [Code] section variable to [Registry]

问题描述

我在使用Inno Setup时遇到问题.

I have a problem with Inno Setup.

我在这里的[Code]部分中使用分辨率检测脚本:
INNO设置:如何获取主显示器的分辨率?

I'm using resolution detection script in [Code] section from here:
INNO Setup: How to get the primary monitor's resolution?

现在我想将xres和yres值放入安装程序的[Registry]部分，如下所示.

And now I want to put xres and yres values to [Registry] section of my installer which looks like this.

Root: HKCU; Subkey: "Software\MyApp\Settings"; Flags: uninsdeletekey; ValueType: dword; \
    ValueName: "ScreenWidth"; ValueData: "XRES"
Root: HKCU; Subkey: "Software\MyApp\Settings"; Flags: uninsdeletekey; ValueType: dword; \
    ValueName: "ScreenHeight"; ValueData: "YRES"

我尝试了此方法如何在Inno Setup吗?，但是我无法正常工作.我尝试过多次自己解决问题，但我放弃了...

I tried this method How to use a Pascal variable in Inno Setup?, but I can't get it work. I tried to solve the problem by myself many times, but I give up...

有人可以帮我解释一下该怎么做吗?
我是Inno Setup的新手，尤其是Pascal.

Can someone help me and explain how to do that?
I'm newbie with Inno Setup, and especially with Pascal.

推荐答案

一种方法可以编写一个 scripted constant 函数，并通过传递的参数返回水平或垂直分辨率.其余的在Inno Setup引擎上:

One way can be writing a single scripted constant function for both dimensions and by the passed parameter return either horizontal or vertical resolution. The rest is upon Inno Setup engine:

[Setup]
AppName=My Program
AppVersion=1.5
DefaultDirName={pf}\My Program

[Registry]
; the GetResolution function used in the following {code:...} scripted constants
; takes as parameter X to retrieve horizontal resolution, Y to retrieve vertical
Root: HKCU; Subkey: "Software\MyApp\Settings"; Flags: uninsdeletekey; ValueType: dword; \
   ValueName: "ScreenWidth"; ValueData: "{code:GetResolution|X}"
Root: HKCU; Subkey: "Software\MyApp\Settings"; Flags: uninsdeletekey; ValueType: dword; \
    ValueName: "ScreenHeight"; ValueData: "{code:GetResolution|Y}"

[Code]
function GetSystemMetrics(nIndex: Integer): Integer;
  external '[e-mail] stdcall';

const
  SM_CXSCREEN = 0;
  SM_CYSCREEN = 1;

function GetResolution(Param: string): string;
begin
  // in the {code:...} constant function call we are passing either
  // X or Y char to its parameter (here it is the Param parameter),
  // so let's decide which dimension we return by the Param's first
  // char (uppercased to allow passing even small x and y)
  case UpperCase(Param[1]) of
    'X': Result := IntToStr(GetSystemMetrics(SM_CXSCREEN));
    'Y': Result := IntToStr(GetSystemMetrics(SM_CYSCREEN));
  end;
end;
