如何运行我通过Internet下载的应用程序,在代码部分中使用,并等待该应用程序完成运行.我有,使用InnoTools下载程序,下载这两个文件,我想,在第二个完成下载后运行该下载,或jdk-8u111-windows-x64.exe,然后继续安装.
[Code]
procedure InitializeWizard();
begin
ITD_Init;
ITD_AddFile('http://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.0.M13/bin/apache-tomcat-9.0.0.M13-windows-x64.zip',expandconstant('{tmp}\apache-tomcat-9.0.0.M13-windows-x64.zip'));
ITD_DownloadAfter(1);
ITD_AddFile('http://files.downloadnow-1.com/s/software/15/62/36/39/jdk-8u111-windows-x64.exe?token=1479511171_b51e94edd4e002c94fd60a570a7dd270&fileName=jdk-8u111-windows-x64.exe',expandconstant('{tmp}\jdk-8u111-windows-x64.exe'));
ITD_DownloadAfter(2);
end;
解决方法
使用其他下载插件,而不是ITD(请参阅下面的原因).
当您包含idp.iss时,它定义了一个全局IDPForm结构.它的Page字段是TWizardPage,代表一个下载页面.下载完成后,使用NextButtonClick中的ID运行下载的文件(下载页面上的“下一步”按钮自动“按下”)：
#include <idp.iss>
[Code]
procedure InitializeWizard;
begin
idpAddFile(
'https://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.0.M13/bin/' +
'apache-tomcat-9.0.0.M13-windows-x64.zip',ExpandConstant('{tmp}\apache-tomcat-9.0.0.M13-windows-x64.zip'));
idpAddFile(
'https://www.example.com/jdk-8u111-windows-x64.exe',ExpandConstant('{tmp}\jdk-8u111-windows-x64.exe'));
idpDownloadAfter(wpSelectDir);
end;
function NextButtonClick(CurPageID: Integer): Boolean;
var
ResultCode: Integer;
FileName: string;
begin
if CurPageID = IDPForm.Page.ID then
begin
FileName := ExpandConstant('{tmp}\jdk-8u111-windows-x64.exe');
Result := Exec(FileName,'',SW_SHOW,ewWaitUntilTerminated,ResultCode);
if not Result then
begin
MsgBox('Cannot execute sub-installer',mbError,MB_OK);
end
else
begin
Result := (ResultCode = 0);
if not Result then
begin
MsgBox('Sub-installer Failed',MB_OK);
end
end;
end
else
begin
Result := True;
end;
end;
虽然您可以使用InnoTools Downloader实现相同功能,但您应该避免使用它：
>它已经过时,不再维护了;
>不支持Unicode Inno Setup(不要在新项目中使用Ansi Inno Setup);
>下载支持HTTPS;
>其下载页面does not scale on high DPI.
无论如何,为了完整性：ITD_DownloadAfter返回TWizardPage,表示下载页面.下载完成后,使用NextButtonClick中的ID运行下载的文件(下载页面上的“下一步”按钮自动“按下”)：
var
DownloadPage: TWizardPage;
procedure InitializeWizard();
begin
ITD_Init;
ITD_AddFile(
'http://www.example.com/jdk-8u111-windows-x64.exe',ExpandConstant('{tmp}\jdk-8u111-windows-x64.exe'));
DownloadPage := ITD_DownloadAfter(wpSelectDir);
end;
function NextButtonClick(CurPageID: Integer): Boolean;
var
ResultCode: Integer;
begin
if CurPageID = DownloadPage.ID then
begin
Result :=
Exec(
ExpandConstant('{tmp}\jdk-8u111-windows-x64.exe'),MB_OK);
end
end;
end
else
begin
Result := True;
end;
end;
