我需要在运行时更改Messages。我有一个AfterInstall过程,检查bat文件是否成功。如果不是,我想在调用WizardForm.Close之前更改ExitSetupMessage的值。我本来希望做这样的事情.ExitSetupMessage:='这是不工作的部分';代码示例将不胜感激。谢谢。
[Languages]
Name: english; MessagesFile: compiler:Default.isl
[Files]
Source: {src}\test.bat; DestDir: {tmp}; AfterInstall: ValidateInstall
[Code]
procedure ValidateInstall();
var
ResultCode : Integer;
begin
if not Exec(ExpandConstant('{tmp}\test.bat'), '', '', SW_HIDE, ewWaitUntilTerminated, ResultCode) then
begin
english.ExitSetupMessage := 'THIS IS THE PART THAT DOES NOT WORK';
WizardForm.Close;
end;
end;
我不知道在运行时更改消息的方法。
但是,在您发布的情况下,我知道一种解决方法。您可以在调用WizardForm.Close
之前设置CustomState
var
CustomState : Boolean;
procedure CancelButtonClick(CurPageID: Integer; var Cancel, Confirm: Boolean);
var
Msg : String;
Res : Integer;
begin
Confirm := False; // Don't show the default dialog.
// Chose which message the custom or default message.
if CustomState then
Msg := 'My Custom Close Message'
else
Msg := SetupMessage(msgExitSetupMessage);
//as the Question
Res := MsgBox(Msg, mbConfirmation,MB_OKCANCEL);
// If they press OK then Cancel the install
Cancel := (Res = IDOK);
end;
副作用是你失去了对话框的Exit Setup?
标题。
当您不想更改消息以保持标题时,可以使用function ExitSetupMsgBox: Boolean;
。
根据http://www.jrsoftware.org/ishelp/index.php?topic=scriptclasses
它应该是
WizardForm.FinishedLabel.Caption := 'Desired text goes here';
