[WiX-users] Deployment Tools Foundation: ApplyPatch Method
I'm trying to use the DTF libraries to apply a Patch to an Msi file and then
extract the updated files from the Patched Msi. I can't get it working, and I'm
at wit's end. Any guidance would be much appreciated.
I can apply the patch and transform to the msi, and the Files table in the Msi
then contains the updates from the patch. That seems good. I then try to use
InstallerPackage.ExtractFiles to extract the files into a directory. When I get
down to a file whose contents is in the CAB in the Patch (netfx.msp), I receive
a "Stream Not Found: netfx_PCW_CAB_NDP" error. I can't figure out how to get
the patch cab (PCW_CAB-NDP) into the Msi. I thought that
InstallerPackage.ApplyPatch would do this, but apparently not.
I'm using netfx.msi and netfx.msp that is in the \upgrades\netfx directory in
the Win 7 distribution for my testing. Here's a shortened version of my code:
// define the variables
string msiPath = @"d:\upgrade\netfx\netfx.msi";
string mspPath = @"d:\upgrade\netfx\netfx.msp";
string transformName = "T320_1ToU1.MST";
// open the Msi file
using (InstallPackage package = new InstallPackage(msiPath,
DatabaseOpenMode.Transact))
{
// open the Msp file
using (PatchPackage patch = new PatchPackage(mspPath))
{
// set the directories for the Msi file
package.WorkingDirectory = unpackSubdirectory;
package.SourceDirectory =
System.IO.Path.GetDirectoryName(msiPath);
// apply the patch
package.ApplyPatch(patch, transformName);
// query the list of files from the Msi
List fileList = new
List(package.ExecuteStringQuery("SELECT `File` FROM `File`", null));
// loop through the files in the fileList
foreach (String fileItem in fileList)
{
// add the string to a FileArray
string[] fileArray = { fileItem };
// extract the files
package.ExtractFiles(fileArray);
}
}
}

[WiX-users] Deployment Tools Foundation: ApplyPatch Method
Blair et al,
Thanks for the info, but I'm still fairly well stuck. If the patch cab remains
in the patch, it seems my code doesn't allow the InstallPackage.ExtractFiles
method to find the patch's cab at extract time. This would make sense as to why
I'm getting a Stream Not Found error.
Is there somewhere specific I need to place the patch file, or some
method/property I need to call to allow the ExtractFiles method to be able to
find the patch cab? I currently have the msi, the msi's exteernal cabs and the
msp in the same directory, which is set as the InstallPackage.SourceDirectory.

Applying the patch adds a row to the media table and changes the file table?s
sequence numbers to reflect the patched files being in the patch?s cab. That
cab will still be in the MSP file.

[WiX-users] Deployment Tools Foundation: ApplyPatch Method
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)

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.
