问题描述
我目前正在安装.NET Framework 4.6.2作为PrepareToInstall事件函数中的必备组件，以便可以获取退出代码，设置NeedsReboot状态或在安装失败时中止操作.我的代码在下面，并且一切正常.
I am currently installing .NET Framework 4.6.2 as a prerequisite in the PrepareToInstall event function so that I can obtain the exit code, set the NeedsReboot status, or abort if installation fails. My code is below and this is all working fine.
var
PrepareToInstallLabel: TNewStaticText;
PrepareToInstallProgressBar: TNewProgressBar;
intDotNetResultCode: Integer;
CancelWithoutPrompt, AbortInstall: Boolean;
function InitializeSetup(): Boolean;
begin
Result := True;
OverwriteDB := False;
CancelWithoutPrompt := False;
AbortInstall := False;
end;
function PrepareToInstall(var NeedsRestart: Boolean): String;
var
intResultCode: Integer;
strInstallType: String;
begin
if not IsDotNet45Installed and IsWindows7Sp1OrAbove then
begin
HidePrepareToInstallGuiControls;
PrepareToInstallLabel.Caption := 'Installing Microsoft .NET Framework 4.6.2...';
ShowPrepareToInstallGuiControls;
ExtractTemporaryFile('NDP462-KB3151800-x86-x64-AllOS-ENU.exe');
if WizardSilent = True then
begin
strInstallType := '/q';
end
else
begin
strInstallType := '/passive';
end;
Exec(ExpandConstant('{tmp}\NDP462-KB3151800-x86-x64-AllOS-ENU.exe'), strInstallType + ' /norestart', '', SW_SHOW,
ewWaitUntilTerminated, intDotNetResultCode);
if (intDotNetResultCode = 0) or (intDotNetResultCode = 1641) or (intDotNetResultCode = 3010) then
begin
Log('Microsoft .NET Framework 4.6.2 installed successfully.' + #13#10 + 'Exit Code: ' + IntToStr(intDotNetResultCode));
CancelWithoutPrompt := False;
AbortInstall := False;
end
else
begin
if WizardSilent = True then
begin
Log('Microsoft .NET Framework 4.6.2 failed to install.' + #13#10 + 'Exit Code: ' + IntToStr(intDotNetResultCode) + #13#10 + 'Setup aborted.');
end
else
begin
MsgBox('Microsoft .NET Framework 4.6.2 failed to install.' + #13#10 + #13#10 +
'Exit Code: ' + IntToStr(intDotNetResultCode) + #13#10 + #13#10 +
'Setup aborted. Click Next or Cancel to exit, or Back to try again.',
mbCriticalError, MB_OK);
end;
PrepareToInstallProgressBar.Visible := False;
PrepareToInstallLabel.Caption := 'Microsoft .NET Framework 4.6.2 failed to install.' + #13#10 + #13#10 + 'Exit Code: ' + IntToStr(intDotNetResultCode) + #13#10 + #13#10 + 'Setup aborted. Click Next or Cancel to exit, or Back to try again.';
CancelWithoutPrompt := True;
AbortInstall := True;
Abort;
end;
end;
end;
procedure InitializeWizard();
begin
//Define the label for the Preparing to Install page
PrepareToInstallLabel := TNewStaticText.Create(WizardForm);
with PrepareToInstallLabel do
begin
Visible := False;
Parent := WizardForm.PreparingPage;
Left := WizardForm.StatusLabel.Left;
Top := WizardForm.StatusLabel.Top;
end;
//Define Progress Bar for the Preparing to Install Page
PrepareToInstallProgressBar := TNewProgressBar.Create(WizardForm);
with PrepareToInstallProgressBar do
begin
Visible := False;
Parent := WizardForm.PreparingPage;
Left := WizardForm.ProgressGauge.Left;
Top := WizardForm.ProgressGauge.Top;
Width := WizardForm.ProgressGauge.Width;
Height := WizardForm.ProgressGauge.Height;
PrepareToInstallProgressBar.Style := npbstMarquee;
end;
end;
procedure CurStepChanged(CurStep: TSetupStep);
begin
if CurStep = ssInstall then
begin
if AbortInstall = True then
begin
Abort;
end;
end;
end;
目前，我正在使用/q或/passive将安装类型设置为无提示或无人值守，以控制.NET Framework安装程序显示的可见GUI的数量，具体取决于Inno Setup的运行方式和使用的方式.选取框样式进度条，指示正在发生某些事情.但是，从Microsoft文档此处 ，似乎可以使用/pipe开关让.NET Framework安装程序报告其安装进度，这可能使它可以交互地更新实际进度的常规样式进度条.这意味着.NET Framework安装程序可能会被完全隐藏，并且Inno Setup用来指示相对进度，这是一个更为整洁的解决方案.不幸的是，我不懂C ++，而且只是一个新手程序员.因此，任何人都可以确认是否可以使用Inno Setup进行这种操作，如果可以，如何进行尝试?
At the moment, I am setting the installation type to either silent or unattended using /q or /passive to control the amount of visible GUI the .NET Framework installer displays, depending on how Inno Setup is running and using a Marquee style progress bar to indicate that something is happening. However, from the Microsoft documentation here, it appears that it is possible to get the .NET Framework installer to report it's install progress back, using the /pipe switch, which might allow it to interactively update a normal style progress bar on the actual progress. This would mean that the .NET Framework installer could be hidden completely and Inno Setup used to indicate the relative progress, which is a much tidier solution. Unfortunately, I do not know C++ and am only a novice programmer. Therefore, can anyone confirm if this is possible to do with Inno Setup and, if so, how it might be attempted?

您可以按以下方式使用它，也可以在安装程序的任何其他地方使用它.
You can use it like below, or on any other place of your installer process.
function NextButtonClick(CurPageID: Integer): Boolean;
begin
Result := True;
if CurPageID = wpReady then
begin
try
InstallNetFramework;
except
MsgBox(GetExceptionMessage, mbError, MB_OK);
Result := False;
end;
end;
end;
下面的屏幕快照显示了Inno Setup中的进度页"如何链接到.NET Framework安装程序(当然，.c框架安装程序被/q开关隐藏了，只是出于获取目的而临时显示了该窗口)屏幕截图).
The following screenshot shows how the "progress page" in Inno Setup is linked to the .NET framework installer (of course the .NET framework installer is hidden by the /q switch, it was just temporarily shown for purposes of obtaining the screenshot).
我已经在
- dotnetfx45_full_x86_x64.exe(.NET Framework 4.5-脱机安装程序)
- NDP462-KB3151800-x86-x64-AllOS-ENU .exe (.NET Framework 4.6.2-脱机安装程序)
- dotnetfx45_full_x86_x64.exe (.NET framework 4.5 - off-line installer)
- NDP462-KB3151800-x86-x64-AllOS-ENU.exe (.NET framework 4.6.2 - off-line installer)
请注意，仅当上述两个安装程序都处于脱机状态时，该代码才考虑InstallSoFar.对于在线安装程序，也应考虑DownloadSoFar.实际上，甚至离线安装程序有时也会下载一些东西.
Note that the code takes into account the InstallSoFar only as both installers above are off-line. For on-line installers, DownloadSoFar should be taken into account too. And actually even off-line installers do sometime download something.
ShellExecuteEx代码取自 Inno Setup Exec()函数，请等待一段有限的时间.. /em>
