[英]How to set version number from Inno Setup Pascal Script
I have a script that reads the version number from an application file.我有一个从应用程序文件中读取版本号的脚本。 Now I need to find a way to place this number in the
AppVersion
directive of Inno Setup.现在我需要找到一种方法将这个数字放在 Inno Setup 的
AppVersion
指令中。
How can I place the return value of my function in the AppVersion
directive?如何将函数的返回值放在
AppVersion
指令中?
Use a scripted constant :使用 脚本常量:
[Setup]
AppVersion={code:GetAppVersion}
[Code]
function GetAppVersion(Param: string): string;
begin
Result := MyFunction;
end;
If the function call is costly, you should cache its value to a global variable and use the cached value in the scripted constant.如果函数调用代价高昂,则应将其值缓存到全局变量中,并在脚本常量中使用缓存值。
