I think I've figured out why InstallPackage.ApplyPath method is failing for me,
and I think this is a bug in the DTF code. Phil's comments got me thinking and
I've done my best to debug what's going on in ApplyPatch. I'm a newbie on
several levels here, so forgive me if I've missed something.
The ApplyPatch method does two basic things: 1) applies the transform to the
database and 2) copies the patch cab from the patch and inserts it into the
database. Applying the transform seems to work correctly, but the problem is in
moving the patch cab into the database.
Before moving the cab, ApplyPatch creates a record for the patch cab in the
Media table, using the string renamePatchCabinet ("netfx_PCW_CAB_NDP" in my
case)
string patchPrefix = Path.GetFileNameWithoutExtension(patchPackage.FilePath) +
"_";
...
string renamePatchCabinet = patchPrefix + patchCabinet;
...
this.Execute("INSERT INTO `Media` (`DiskId`, `LastSequence`, `Cabinet`) VALUES
({0}, '{1}', '#{2}')", renamePatchMediaDiskId, lastSeq, renamePatchCabinet);
When ApplyPatch inserts the cab into the database, the cab is named with the
patchCabinet string ("PCW_CAB_NDP" in my case)
patchCabRec[1] = patchCabinet;
patchCabRec.SetStream(2, patchCabFile);
this.Execute("INSERT INTO `_Streams` (`Name`, `Data`) VALUES (?, ?)",
patchCabRec);
So when I call InstallPackage.ExtractFiles, I get an error message "Stream Not
Found: netfx_PCW_CAB_NDP", as the stream is actually named "PCW_CAB_NDP" in the
database.
If I change: "patchCabRec[1] = patchCabinet;" to "patchCabRec[1] =
renamePatchCabinet;", InstallPackage.ExtractFiles will extract all this files
without any errors.
On a related note, I'm having a challenge with InstallPackage.Commit(). If I
instantiate InstallPackage with DatabaseOpenMode.Transact,
when I call InstallPackage.Commit(), I get a "function failed during execution"
exception with the following StackTrace:
at Microsoft.Deployment.WindowsInstaller.SummaryInfo.Persist()
at Microsoft.Deployment.WindowsInstaller.Database.Commit()
...
If I instantiate InstallPackage with DatabaseOpenMode.Direct, at the end of my
using() I also get a "function failed during execution" exception with the
following StackTrace:
at Microsoft.Deployment.WindowsInstaller.SummaryInfo.Persist()
at Microsoft.Deployment.WindowsInstaller.Database.Commit()
at Microsoft.Deployment.WindowsInstaller.Database.Dispose(Boolean disposing)
at Microsoft.Deployment.WindowsInstaller.InstallerHandle.Dispose()
...
Strangely, I can use instantiate Database with DatabaseOpenMode.Transact and
Database.Commit() seems to work fine. (I haven't tried Database with
DatabaseOpenMode.Direct)
>From what I can tell in the source, InstallPackage.Commit() is inherited from
>Database.Commit(), so I'm a bit perplexed. Any ideas?

It's not clear to me what that ApplyPatch method is doing under the covers.
It's not MsiApplyPatch(), because that does an install of the patch. It
appears to actually be MsiDatabaseAplyTransform() judging from the
transform parameter, and that just modifies the tables.
This might help:
http://blogs.msdn.com/b/heaths/archive/2006/02/14/532200.aspx
particularly where he mentions using MsiOpenDatabase on a patch file and
then looking for streams.
