在Inno Setup中，我创建了一个自定义页面，其中包含以下代码，其中包含3个文本框。

现在我要在自定义表单上单击下一步按钮验证该文本框。如果在text.text ='2121212'中，用户输入了一些文本，则只启用了下一个按钮。

CustomForm_Caption=CustomForm Caption
CustomForm_Description=CustomForm Description
CustomForm_Label1_Caption0=College Name:

CustomForm_Label3_Caption0=Product ID:

这应该让你开始：

    ; This script shows how to insert custom wizard pages into Setup and how to handle
    ; these pages. Furthermore it shows how to 'communicate' between the [Code] section
    ; and the regular Inno Setup sections using {code:...} constants. Finally it shows
    ; how to customize the settings text on the 'Ready To Install' page.

    [Setup]
    AppName=My Program
    AppVerName=My Program version 1.5
    DefaultDirName={pf}\My Program
    DisableProgramGroupPage = yes
    UninstallDisplayIcon={app}\MyProg.exe
    OutputDir=userdocs:Inno Setup Examples Output

    [Files]
    Source: "MyProg.exe"; DestDir: "{app}"; Flags: ignoreversion

    [CustomMessages]
    CustomForm_Caption=CustomForm Caption
    CustomForm_Description=CustomForm Description
    CustomForm_Label1_Caption0=College Name:
    CustomForm_Label2_Caption0=Product Type:
    CustomForm_Label3_Caption0=Product ID:

    [Code]
    Var
    Page: TWizardPage;
    Label1: TLabel;
    Label2: TLabel;
    Label3: TLabel;
    Edit1: TEdit;
    Edit2: TEdit;
    Edit3: TEdit;
    Edit4: TEdit;
    Edit5: TEdit;
    Edit6: TEdit;

    procedure  EdtOnChange (Sender: TObject);
    Var
    MyEdit : TEdit;
    begin
    MyEdit := TEdit(Sender);
    if MyEdit.Text = '2121212' then
      WizardForm.NextButton.Enabled := true
    Else
      WizardForm.NextButton.Enabled := false;
    end;


    procedure InitializeWizard;
    Var
      CheckBox: TCheckBox;
    begin
      Page := CreateCustomPage( wpWelcome, ExpandConstant('{cm:CustomForm_Caption}'), ExpandConstant('{cm:CustomForm_Description}') );


    { Label1 } Label1 := TLabel.Create(Page); with Label1 do begin Parent := Page.Surface; Caption := ExpandConstant('{cm:CustomForm_Label1_Caption0}'); Left := ScaleX(16); Top := ScaleY(24); Width := ScaleX(70); Height := ScaleY(13); end;

    { Label2 } Label2 := TLabel.Create(Page); with Label2 do begin Parent := Page.Surface; Caption := ExpandConstant('{cm:CustomForm_Label2_Caption0}'); Left := ScaleX(17); Top := ScaleY(56); Width := ScaleX(70); Height := ScaleY(13); end;

    { Label3 } Label3 := TLabel.Create(Page); with Label3 do begin Parent := Page.Surface; Caption := ExpandConstant('{cm:CustomForm_Label3_Caption0}'); Left := ScaleX(17); Top := ScaleY(88); Width := ScaleX(70); Height := ScaleY(13); end;

    { Edit1 } Edit1 := TEdit.Create(Page); with Edit1 do begin Parent := Page.Surface; Left := ScaleX(115); Top := ScaleY(24); Width := ScaleX(273); Height := ScaleY(21); TabOrder := 0; end;

    { Edit2 } Edit2 := TEdit.Create(Page); with Edit2 do begin Parent := Page.Surface; Left := ScaleX(115); Top := ScaleY(56); Width := ScaleX(273); Height := ScaleY(21); TabOrder := 1; end;

    { Edit3 } Edit3 := TEdit.Create(Page); with Edit3 do begin Parent := Page.Surface; Left := ScaleX(115); Top := ScaleY(88); Width := ScaleX(273); Height := ScaleY(21); TabOrder := 2; end;

      Edit3.OnChange := @EdtOnChange;

    end;

    procedure CurPageChanged(CurPageID: Integer);
    begin
    If CurPageID = Page.ID Then
      WizardForm.NextButton.Enabled := false;
    end;

    end.

如上所述，它会检查第三个文本框中的“2121212”值。如果您想在第一个或第二个框中使用它，则需要为相应的编辑框添加OnChange事件处理程序。
