[英]VS2010 on Win7, installer class within a setup is not called
它是 setupproject 中的一个安装程序类,它位于 winform 项目中。 直到现在我没有任何错误消息,只是没有被调用。 RunInstallerAttribute 设置为 true。
唯一剩下的是“主要空白”,但我不能说,因为 winform 项目需要它。
这是整个代码:

using System.Threading;

最可能的原因是您没有在安装项目中将程序集添加为自定义操作,因为您没有提到这样做。
它现在有效。 我创建了那些“CommonAppDataFolder”,在 ac# 项目中似乎需要它。 几年前我用 vb.net proejct 制作它,不记得需要它。 它需要安装应用程序,当然具有这些特殊权限,但安装程序的调用并不依赖于它。
最后,我必须在“Commit”中取出使用部分“using (Process process = new Process())”。 因为无论我对 -filename- 和 -argument- 设置什么,它总是会抛出一个错误, - 它无法找到文件夹“C/Program86/....myApp.exe”。
当我发现这个使用部分时,我真的很高兴,以为我现在还剩下什么来关闭最终的安装窗口“安装完成”。 我总是不得不手动关闭这个窗口。
Commit 过程现在看起来像这样:
public override void Commit(IDictionary savedState)
{
string strPath = "";
var myProcess = new Process();
try
{
base.Commit(savedState);
strPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData), "Test");
strPath = Path.Combine(strPath, "myApp.exe");
myProcess.StartInfo.FileName = strPath;
myProcess.StartInfo.CreateNoWindow = false;
myProcess.Start();
myProcess.WaitForExit(500);
myProcess.Close();
myProcess = null;
}
catch (Exception ex)
{
MessageBox.Show("public override void Commit " + ex.ToString());
Application.Exit();
}
}
