我对Inno Setup有疑问。
我在[Code]
部分使用分辨率检测脚本:
INNO Setup: How to get the primary monitor's resolution?
现在我想将xres
和yres
值添加到我的安装程序的[Registry]
部分,看起来像这样。
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"
我尝试了这种方法How to use a Pascal variable in Inno Setup?,但我无法让它发挥作用。我试图自己多次解决这个问题,但我放弃了......
有人可以帮助我并解释如何做到这一点吗? 我是Inno Setup的新手,尤其是Pascal。
答案 0 :(得分:3)
一种方法是为两个维度编写单个scripted constant
函数,并通过传递的参数返回水平或垂直分辨率。剩下的就是Inno Setup引擎:
[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 'GetSystemMetrics@user32.dll 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;
