inno-setup - Inno 设置 : how to use {app} in InitializeWizard Procedure

Question

如何访问 {app} InitializeWizard 中的变量程序 ？

当我使用 ExpandConstant('{app}');我收到下一条错误消息:

An attempt to expand the {app} constant was made before it was initialized

Answer 1

找到了答案:)
原型(prototype):

function WizardDirValue: String;

描述:

Returns the current contents of the edit control on the Select Destination Location page of the wizard.

Unlike ExpandConstant('{app}'), this function will not fail if called after the wizard is shown but prior to the user selecting a directory. Rather, it will return the default directory name.
