Updating UMDF drivers during development - driver

I am having some trouble updating UMDF drivers using "devcon" during a
standard code-deploy-debug cycle. The problem is that "devcon update" isn't
really updating anything unless the version number or the date of the DLL
file and the INF file has changed from what is stored in the system's driver
cache folder. After a maddening series of experiments I've discovered that
one way to force the thing to use the latest files is by doing the
following:
Change the parameters passed to
"stampinf.exe" in "makefile.inc" by
explicitly setting a version with
the "-v" option.
Modify the
resource script file ("DRIVER_NAME.rc") to first define
VER_USE_OTHER_MAJOR_MINOR_VER
before including "ntverp.h" and then
explicitly define
VER_PRODUCTMAJORVERSION and
VER_PRODUCTMINORVERSION. You'll
note that this system does not allow
us to change the build and the
revision numbers. On Win7 this
seems to be fixed at 7600 and 16385
in "ntverp.h". Is this by design?
So, I first modify "makefile.inc" and set the "-v" option to something like
"1.1.7600.16385" manually incrementing the minor version for every single
build and then modify the RC file and update VER_PRODUCTMINORVERSION with
the same number.
Alternatively, if I run a command prompt under the SYSTEM account and go and
delete the driver cache folder in
"C:\windows\system32\DriverStore\FileRepository\DRIVER FOLDER" before
running "devcon" then that works too.
Now, I am thinking I am missing something fairly basic here as this seems to
be a rather painful way of doing it. Please help! Thanks!

Why can't you just unplug the device and replace the unloaded DLL? You shouldn't need to reinstall the driver, just replace the module. Note that you shouldn't do this during production or anything that has to do with customers, but if you're writing a driver, just slam in the new module with the same version number.
On Win7 this seems to be fixed at 7600 and 16385 in "ntverp.h". Is this by design?
Yep, at least until the next service pack

As Paul Betts has suggested above, the way to go seems to be to simply replace the UMDF DLL directly in the driver folder (for e.g. c:\windows\system32\drivers\umdf\) after disabling the device either in the device manager or using "devcon". I'd asked this question on Microsoft's device drivers newsgroup before posting here but hadn't got a satisfactory response - but some folks ended up responding there after I posted here! So I'll put up a link to that post as well:

not enough space for environment appears when executing ".exe" file

I am trying to use an application called CLUT.exe which is an old application for MS-DOS that can be used to reindex NTX files for DBF databases.
(This is not the main topic, but I am just writing this if someone wants to test the app and don't trust at all about the content).
The problem starts when trying to run the command line version through console (cmd.exe) and this error appears:
C:\>CLUT.exe [arg1] [arg2] [arg3]
run-time error R6009
- not enough space for environment
So, according to what I've searched, this could be a possible solution:
http://support.microsoft.com/default.aspx?scid=kb;en-us;230205
but it doesn't work and every alternative that I found to solve this over the internet is the same.
Another alternative could be to make right-click in the .exe file, go to Properties then Memory tab and increase the Initial environment memory from Auto to the max value but it doesn't work too.
Well, I am stuck and no "possible" solution is working for me. If someone is interested, knows more about this issue and want to test, you can download the application from here (click "Free Download" green button):
http://www.filebasket.com/free/Development-Clipper-programming-language/clut-exe/13996.html
or directly from my DropBox:
https://dl.dropbox.com/u/15208254/stackoverflow/clut_214.rar
Just to know, I am using Windows 7 and the CLUT.exe application is a Clipper based app (old programming language) that may run under windows console (cmd.exe).
Wikipedia does mention other dos emulators but, oddly, doesn't mention BOCHS.
Reindexing NTX files is not a difficult thing to do, and can be done with tools other than CLUT. For example, many of the utilities listed on this part of Download32 could be used. Otherwise, you could write your own using Harbour Project or xHarbour. Or contact me off list and I'll cook up something in Clipper 5.3.
LATER
If I read the README correctly for CLUT, it's a replacement for the DBU utility that comes with Clipper 5.x. I can supply you with a build of that if you're unsuccessful with other approaches.

Using WiX, Windows Services are not installed after a downgrade

While testing the downgrade functionality of one of our WiX-built MSIs, I have noticed something odd.
I have allowed downgrades in the MajorUpgrade element and I have scheduled that element to be afterInstallInitialize (but I have tried it thoroughly with afterInstallValidate and I experience the same problem; we can't have it after that action, but I thought I'd test it).
Many of the files (e.g. the DLLs in our Service's bin folder) are of a higher version, with each release; therefore, the version we are downgrading to includes files of a lower version. Yet all of those files are installed fine, during the downgrade, apart from the Service EXE files; further, the Services are also not installed in Windows.
Considering all of the above, after spending two days on this problem, and after much searching, I appear to be at a loss.
I have tried two things that seem to provide some hope:
1) I have tried setting the REINSTALLMODE property to amus. This ensures that the EXE files are installed, along with the Windows Services. But most things I read about that property warn against using it, and I even have to surpress ICE40, in order to get my package to build, when setting that property. This all concerns me, as I am not sure what negative effects could be missed, if I use this property in my MSI files.
2) When I remove the KeyPath attribute from the File elements that mark up the Service EXE files and place that attribute on the Component element instead, the Service EXE files are installed onto the system during the downgrade, but the Services are still not installed in Windows. After looking into this, it seems that the KeyPath attribute must be on the File element, if I'd like Services to be installed. So it seems to me as if this idea will not help.
Any help or advice would be very much appreciated. We really could do with providing downgrade functionality.
Thank you all for your time.
MSI is essentially opposed to the idea of downgrades. Once a file is on the machine, MSI tries very hard to keep the latest version of the file around as, among other reasons, downgrading the file can re-introduce a security vulnerability. I'd suggest not directly supporting downgrades; instead, you can show a message that tells the user to uninstall the higher version first.
My solution was to use Burn to provide the 'downgrade' functionality using a custom bootstrapper application.
The bootstrapper detects, downloads, and then installs the new version. In the case of a downgrade it performs an uninstall prior to the install. However, this requires that you execute the bootstrapper of the currently installed version to get the ability to uninstall.
You then also need to worry about any state that will be removed as a consequence of uninstalling, this needs to be preserved the same way as you would during an upgrade.
Using Wix, to allow downgrading and still have the Windows Service install properly on downgrade, use the following combination:
<Wix ...>
<Product ...>
<Property Id="REINSTALLMODE" Value="amus" />
<MajorUpgrade Schedule="afterInstallInitialize" AllowDowngrades="yes" />
I was also using WixSharp to generate the .wxs file and used this code to do so:
// https://learn.microsoft.com/en-us/windows/win32/msi/reinstallmode
// a = Force all files to be reinstalled, regardless of checksum or version.
// m = Rewrite all required registry entries from the Registry Table that go to the HKEY_LOCAL_MACHINE or HKEY_CLASSES_ROOT registry hive. Rewrite all information from the Class Table, Verb Table, PublishComponent Table, ProgID Table, MIME Table, Icon Table, Extension Table, and AppID Table regardless of machine or user assignment.Reinstall all qualified components.When reinstalling an application, this option runs the RegisterTypeLibraries and InstallODBC actions.
// u = Rewrite all required registry entries from the Registry Table that go to theHKEY_CURRENT_USER or HKEY_USERS registry hive.
// s = Reinstall all shortcuts and re-cache all icons overwriting any existing shortcuts and icons.
project.AddXml("Wix/Product", "<Property Id=\"REINSTALLMODE\" Value=\"amus\" />");
// Allow downgrading versions
// https://wixtoolset.org/documentation/manual/v3/xsd/wix/majorupgrade.html
project.AddXml("Wix/Product", "<MajorUpgrade Schedule=\"afterInstallInitialize\" AllowDowngrades=\"yes\" />");

Why does my program say "folder does not exist" when run on Windows 2008?

We have a Delphi program whose task is like a service program. It watches a particular folder for a certain period, and it works great on Windows XP and 2003, but on Windows 2008r2 64bit, when it wants to create an automatic folder, it will show this message:
The ... folder does not exist. The file may have been moved or deleted.
This message causes the program to halt, which is not good; it should not be interrupted.
What can I do about this?
P.S.: I really don't have any idea whether to post my problem in Stack Overflow or Server Fault, so I've guessed it should be here.
It's likely the VirtualStore, if you're trying to store beneath Program Files (either one). See my writeup:
http://www.clipboardextender.com/off-topic/vista-program-files-hide-and-seek
You've left out the ... folder name. While that's understandable, it wouldn't happen to have anything to do with program files (which on x64 will be split in 2 directories) would it?
Windows Server 2008 is able to use 'virtual' file pathes. That means: 'what you see is not what you get'. The Windows Explorer just shows you the 'display' name. Check the file path with cmd.exe, if the path you are trying to use does realy exist.
The reason is of cause the File Virtualization (see for example http://msdn.microsoft.com/en-us/library/bb756960.aspx and http://technet.microsoft.com/en-us/magazine/2007.06.uac.aspx).
Because we on stackoverflow.com and not on serverfault.com I want add to all other answers that you can use Wow64DisableWow64FsRedirection, Wow64RevertWow64FsRedirection and Wow64EnableWow64FsRedirection functions (see http://msdn.microsoft.com/en-us/library/aa365743.aspx) to control the File Virtualization in your program. An example of the usage of this functions in C# you can find here http://www.pinvoke.net/default.aspx/kernel32.wow64disablewow64fsredirection.
You'll need to tell us the exact path and how do you go about constructing it. It can be as simple as the app not using env variable expansion but assuming that user's folders are where they were before.
Path virtualization (there are 2 kids actually) that people mentioned will hit you only if your app is trying to mess with system folders.
More puzzling problem will hit you if you are not expanding env vars like APPDATA, LOCALAPPDATA etc. and not expecting that there's more of them on Win7 and 2k8. Not only that default paths of user's files changed but some of them can also be on network shares - for the same user. So if you were running based on expectation that all user's stuff will be at definite paths under say %USERPROFILE% you can get hit by several surprises. Also notice %ProgramData% .
Fastest way to find out - open cmd.exe, run set and if you see some paths that you are constructing in alternative ways, take notice that you need to start expanding env vars for them. Then open cmd.exe as a 32-bit app and check set again. You can also pick them up via Process Explorer from some running 32-bit or 64-bit app.
Switching your app to 64-bit build will resolve most of virtualization issues but not the env var expansion. Also if your app is touching system folders you need to request elevated run from the code or even better make the manifest and declare it there. Then OS will yell at user up front if his UAC is on and your app will avoid that 2nd virtualization. BTW, virtualization is controllable via group policies so it might be present on some boxes and missing on others.

Delphi 2010: how to stamp file version in *.pas and increment it on each save w/o CVS/SVN tools?

How do I have in each *.pas file it's version, incrementing on each save in some comment line? I have plenty of files on three PCs and I need to have a possibility to quickly check their versions against each other.
This problem is easily solved by some centralized version control, but some sources I have cannot be trusted to external servers and are kept on TrueCrypt volumes.
May be some addon can do that for me? Something like changing $Version: to $Version: 121212 on each save, incrementing this value?
May be there is another way also of solving this problem?
Read this chapter about keyword substitution in Subversion.
In short: you have to enable keyword substitution for your files via svn propset svn:keywords ... and insert the revision keyword in these files.
You should try a DVCS like Mercurial. It doesn't need a centralized server while still giving you the benefits of a VCS.
It will also make it easy to synchronize the changes made on each PC to the others.
You may also look at Git : http://git-scm.com/
Don't know if one already exists, but you can write a Delphi plug-in (using its OTA interface) to achieve what you need. Although of course it won't work well if more than one developer works on the same file, unless you use an external, shared counter.
Note that locally hosting subversion can mean filesystem access. i.e. you don't even have to set http. Just point place the repository in your (already) encrypted hard disk, and instead of an URL, use a reference like \share\directory\svn\repo\project1 or C:\svn\repo\project1

Copy Delphi Profile

My computer crashed recently. We have a Delphi app that takes a lot of work to get running.
One of my co-workers has it all installed still. Is there a way to copy the stuff stored in the palette? And the library paths?
I am using Delphi 5 (I know it is very very very old)
That information is stored in the Registry. I don't know exactly how Delphi 5 does it, but try looking for a key called HKEY_CURRENT_USER\Software\Borland\Delphi\5 or something like that. You'll find all the registration information under that key, including a list of installed packages. You can export the keys to a registry file, copy it to the new computer and install it.
Standard disclaimer: Mucking around in the registry manually can be risky if you don't know what you're doing. Be very careful, and if this solution causes your computer to crash, your house to burn down, or demons to come flying out your nose, it's not my fault.
Try CNWizards which has an export functionality for your IDE settings. You can use the same tool restore them on the new machine. We use it to get the same settings on every development machine. In that way we can ensure that all builds are the same, regardless of who built it.
Based on my experience of having done this a few times(!), the most important registry keys are:
HKEY_CURRENT_USER\Software\Borland\Delphi\5.0\Known Packages
HKEY_CURRENT_USER\Software\Borland\Delphi\5.0\Library
and possibly
HKEY_CURRENT_USER\Software\Borland\Delphi\5.0\Known IDE Packages
and maybe
HKEY_CURRENT_USER\Software\Borland\Delphi\5.0\Palette
HKEY_CURRENT_USER\Software\Borland\Delphi\5.0\Palette Defaults
So long as you have done a standard D5 installation first.
It's easier/more reliable to let the IDE fill in the other bits as you start using it and you change options as appropriate. Some component packages, eg madExcept, DevExpress etc are often best re-installed using their own installers anyway.
Unless you're going to have multiple users on the same machine using Delphi then the HKLM stuff isn't really all that important - I don't think.
As a related aside - I have learned that a good way to handle this is to build a FinalBuilder script (or similar) to set up my Delphi environment each time I decide to use a new machine/installation. I copy/download/checkout (which can be done in FB too) all package source then use FB to compile it, copy it, create dirs, and fill in the appropriate registry keys etc. I always get a consistent environment and makes it much easier to rebuild individual components or packages as and when they get upgraded too. The items can also be put into the script in 'dependency order' so that you know to re-compile a dependent package if something else changes. I now have a single FB sciprt that builds D5, D2007, D2009, D2010 environments and packages of all my main components, all depending on which compiler(s) I'm interested in which I indicate by a simple variable. Well worth it.
Seems to have just worked for me on a Win 7, SP1 and Delphi 5
Logged as user with Delphi & 3rd party components installed.
registry export
hkey current user\software\borland
(no other borland products so selected Borland)
rather than Borland\Delphi\5.0)
Logged into pc as new user.
Did not start Delphi5 (i.e. never started for this user).
Regedit File, Import
Started Delphi all components, including lots of 3rd
party, present.
Project compiled as expected under new user.
