Inno Setup Compiler:如何编辑INI文件并用{app}常量替换值 [英] Inno Setup Compiler: How to edit INI file and replace a value with {app} constant

问题描述

我有一个INI文件，其中多次包含c:/wamp.

I have a INI file wich contains c:/wamp many times.

如何用{app}扩展/选择的常量值替换此文本?

How can I replace this text with the {app} extended/chosen constant value?

我现在知道如何替换单个值:

I know now how to replace a single value:

[INI]
Filename: "{app}\wampmanager.conf"; Section: "main"; Key: "installDir"; String: """{app}"""

我正在从此处

推荐答案

这是TLama所说的危险解决方案.

This is risky solution as TLama says.

您必须在某个时候调用此过程，例如在ssDone上或作为AfterInstall

You have to call this procedure at some point, e.g. on ssDone or as an AfterInstall

[Code]
procedure Update;
var
A: AnsiString;
U: String;
begin
    LoadStringFromFile(ExpandConstant('{app}\wampmanager.conf'), A);
    U := A;
    StringChange(U, 'c:/wamp', ExpandConstant('{app}'));
    A := U;
    SaveStringToFile(ExpandConstant('{app}\wampmanager.conf'), A, False);
end;
