Hi,
I have exception when this code is executed:
foreach (ComponentInfo componentInfo in session.Components)
{}.
Exeption is:
System.Reflection.TargetInvocationException: Exception has been thrown
by the target of an invocation. --->
Microsoft.Deployment.WindowsInstaller.InstallerException: Function
failed during execution.

I looked on source code of "ComponentInfoCollection" class and found
that method GetEnumerator missing "compView.Execute()" command before
"foreach (Record compRec in compView) using (compRec). row.
public IEnumerator<ComponentInfo> GetEnumerator()
{
using (View compView = this.session.Database.OpenView(
"SELECT `Component` FROM `Component`"))
{
///////////////////// Missing code ////////////////
/////// compView.Execute();
/////////////////////////////////////////////////////////
foreach (Record compRec in compView) using (compRec)
{
string comp = compRec.GetString(1);
yield return new ComponentInfo(this.session, comp);
}
}
}
I don't have VS2008, so I can not recompile DTF, but I think this is a
problem why I receive exception.
Thanks,
Dima
