This seems so trivial, yet I can't get it to work..
I have an msi.dll wrapper (named Interop.WindowsInstaller.dll) which I need to sign. The way to do it is by signing it upon import (this specific case is even documented in MSDN: http://msdn.microsoft.com/en-us/library/zec56a0w.aspx).
BUT - no matter how I do it (w/ or w/o a keyfile, w/ or w/o adding "/delaysign"), the generated assemly's size is always 36,864 bytes and when viewing the DLL's properties there is no "Digital Signatures" tab (needless to say - the DLL is NOT signed).
What am I missing here?? (... HELP!...)
[Note: Eventually I got a hint from Karel Zikmund on this thread, which helped me solve the mystery. I'll paste my reply here - for the greater good].
So, I used the following line to sign-upon-import the assembly:
tlbimp C:\WINDOWS\system32\msi.dll /out:Interop.WindowsInstaller.dll /keyfile:MyKey.snk
I then copied the file to the appropriate location and built the project, but each time the build failed on the following error: Assembly generation failed -- Referenced assembly 'Interop.WindowsInstaller' does not have a strong name.
I thought the problem was with the tlbimp line, but after reading Karel Zikmund's reply and verifying that the DLL is strong-named (using sn -vf Interop.WindowsInstaller) I found out the problem.
Adding a reference to the "Microsoft Windows Installer Object Library" COM object actually planted a code block into the .csproj file.
I didn't realize it, but this block caused the DLL file to be regenerated from scratch upon each time the project was built. The generated file, of course, was not strong-named anymore.
The way I resolved it was to remove the reference to "Microsoft Windows Installer Object Library" from the project, and add a direct file reference to the imported (and already signed) Interop.WindowsInstaller.dll file.

Using Eclipse 2020 with 2 different Projects. Each Project has their own Workspace.
Workspace1/Project1 Run as expected.
Workspace2/Project2 generates the following error indicating an inability to find MyJarFile.jar:
All the Build values are the same, but when comparing the Dependencies between the working and failing environment I noticed the following.
The working environment shows reference to MyJarFile.jar as an actual path reference.
The failing environment shows reference to MyJarFile.jar as a reference via the Project Name.
The strange thing is when I first Add MyJarFile.jar it shows the actual path name, but after closing and reopening the Dependencies tab, it converts the \MyProject\ reference.
In both scenarios it has been confirmed the file exists.
Also, the addition of the File was done using the dialogbox so that also confirms it exists.
Questions:
1 - Is there a setting which dictates when the actual directory reference is shown and when the \Project\ reference is used?
2 - When the \Project\ reference is used, is there an extra step required so the associated file is actually found?
I am using Conan package manager on Windows to create a package. The conan command to create the package copies files to a folder within %USERPROFILE%\.conan (or C:\Users\xxxxxxx\.conan). Then from this location it builds a Visual Studio project and ultimately calls doxygen.exe to create a .chm help file in a post-build command. The doxygen command fails with:
error : failed to run html help compiler on index.hhp
Further investigation reveals the hhc.exe command executed by doxygen is failing with:
C:\Users\xxxxxxx\.conan\data\Module\1.0.0\user\channel\build\524dc97e4a3dd1f774ea3897f9e4faf26c5457d2\Documentation>"C:/Program Files (x86)/HTML Help Workshop/hhc.exe" html\index.hhp
HHC5010: Error: Cannot open "C:\Users\xxxxxxx\data\Module\1.0.0\user\channel\build\524dc97e4a3dd1f774ea3897f9e4faf26c5457d2\Documentation\html\Module.chm". Compilation stopped.
Close inspection reveals that in the error message, the ".conan" folder is missing. Sure enough, I confirmed that hhc.exe fails when the index.hpp resides in a folder that has a parent folder that starts with a ".".
Attempts to resolve this:
changing the Doxyfile setting OUTPUT_DIRECTORY to "$(TMP)/DoxygenModule" resolves the error, but creates the .chm file in another location, which I do not prefer.
navigating to the 8DOT3 name of the ".conan" folder, which is "CONAN~1", to run the hhc.exe command, succeeds, but unfortunately I have no way of getting conan to use this 8DOT3 path for creating the package. E.g. C:\Users\xxxxxxx\CONAN~1\...
I can live with the using the %TMP% folder but would prefer generating the .chm in the current folder. Anyone have any ideas?
HTML Help Workshop v1.31 is installed on my machine at C:\Program Files (x86)\HTML Help Workshop, probably from a Visual Studio installation (not sure). I attempted using a version downloaded from Microsoft website (v1.30) as well, which made no difference.
Other info: Conan version 1.18.0, Doxygen version 1.8.14, Windows 10 Version 1809
Unfortunately not a solution, but this is a known limitation in the hhc.exe, see: https://social.msdn.microsoft.com/Forums/en-US/0681145c-223b-498c-b7bf-be83209cbf4e/issue-with-html-workshop-in-a-windows-container?forum=visualstudiogeneral
HTML Help 1.x command line compiler hhc.exe cannot compile CHM file to folder whose full path contains folder name starting with dot. If you have that problem, you probably specified output path with folder starting with dot, e.g. "d:\My files.NET\documentation". You can use dots in folder names but not at the beginning.
Edit 2019-11-15:
I've just pushed a proposed patch to github (pull request 7402, https://github.com/doxygen/doxygen/pull/7402).
This proposed patch changes inside doxygen from the current directory to the short named current directory, but just for the HTML Help compilation.
Edit 2019-11-16:
Code has been integrated in the master version on github.
This is not an answer either. Actually, you found the answer and workaround[s] yourself.
Use OUTPUT_DIRECTORY to specify a directory containing no folder names beginning with periods.
The error you described is a known issue of the MS HTML Help compiler. More general, the HTML Help compiler does not like some folder and file names. Try and stick with these characters _, a..z, A..Z, 0..9. Do not use these signs in particular ., -, # .
Please note that the proprietary CHM file format is about 20 years old (Windows 95, ...). HTML Help is in maintenance mode, which means no new features and bug fixes are expected for either the runtime or the compiler. All mainstream development on HH has stopped.
There is no way to avoid this error if a directory name above begins with a period. Not even if only the necessary files are written by Doxygen and compiling of the index.hhp is done by a third-party tool like FAR HTML using your path that contains .conan. This is because all applications are using the faulty HHA.dll.
The above applies of course to the entire workflow you have described. Maybe you can interrupt it.
Doxygen can be configured not to call the HTMLHelp compiler. Just uncheck the GENERATE_HTMLHELP option (DoxyWizard: Experts > Topics > HTML). You have all files generated by Doxygen in your preferred output directory - but of course without the CHM file. This can be imported later e.g. by HelpNDoc and compiled as a CHM file in another location.
If you can interrupt the workflow and can also make changes to Doxygen's settings, then a preference setting of OUTPUT_DIRECTORY to e.g. C:/CacheMenu/CONAN~1/DOXYGE~1 also works as expected (here used as test case).
No matter what you do, your workaround and copy and paste from another directory outside is a quick solution at this stage. Please note the EDIT in #albert's answer.
I have three files ImgProc.h, ImgProc.lib, and ImgProc.dll created by Matlab. I imported them to my VSC++ 2012 MFC project, but when I ran it, the error occurred. I did add the ImgProc.lib into the linker-> input->additional dependencies, Copied 3 files into project directory.
I could not add references. Because when I tried, it was empty like:
that
I really appreciate if someone could help me.
ImgProc.dll must be available at runtime in your application's directory. You need to manually copy this file to your output directories for both Debug and Release builds. Alternatively you can create a post-build step that does the copying. Having ImgProc.dll in your project directory is not enough - your project directory is not part of the Dynamic-Link Library Search Order.
Say I have a SqlClr project called MySqlClrProject, which builds the file MySqlClrProject.dll. I've observed that the Build output file name can be either MySqlClrProject or MySqlClrProject.dll, but either way will produce a file named MySqlClrProject.dll. I also have another project in my solution, called MyClassLibrary, which has a project reference to MySqlClrProject. When I build MyClassLibrary, I'll see this error:
CS0006: Metadata file 'C:\devStuff\MySqlClrProject\bin\Debug\MySqlClrProject' could not be found
Before that, in the output, I see this:
ResolveAssemblyReferences:
5> Primary reference "MySqlClrProject".
5> Could not find dependent files. Expected file "C:\devStuff\MySqlClrProject\bin\Debug\MySqlClrProject" does not exist.
5> Could not find dependent files. Expected file "C:\devStuff\MySqlClrProject\bin\Debug\MySqlClrProject" does not exist.
5> Resolved file path is "C:\devStuff\MySqlClrProject\bin\Debug\MySqlClrProject".
5> Reference found at search path location "".
5> Found related file "C:\devStuff\MySqlClrProject\bin\Debug\MySqlClrProject.pdb".
5> Found related file "C:\devStuff\MySqlClrProject\bin\Debug\MySqlClrProject.xml".
5> The ImageRuntimeVersion for this reference is "".
If I add a post build step that copies MySqlClrProject.dll to MySqlClrProject, all is well. Alternatively, if I reference the dll directly, as opposed to using a project reference, then, again, it works fine. I'd really rather not go either of those routes...
Anyway, has anyone else seen this? Anything I might be doing wrong? I know VS2012 is very new, and they've changed a lot when it comes to SqlClr projects, but I'm wondering if the problem is on my side or Microsoft's.
Thanks.
My exe depends on ntdll, user32 and kernel32. I save these dlls as a local copy and change the first letter as "V".
I then edit the exe's Import dll name as Vernel32.dll from kernel32. The application works fine by loading vernel32.dll in local space.
Next i edit the exe's import dll spec as vtdll as ntdll, the process loads vtdll from local, runs its code and throws an _stackhash exception on vtdll instructions.
I need this for developing my appliction to bundle all windows dependencies. Does any body have any idea, Why ntdll cant be run in local space.
No! You cannot try to replace ntdll. It is mapped by the kernel into every single process, probably before any of your code is even loaded. It has an intricate connection with the kernel. It knows all the correct system call numbers. Try using ntdll from NT 5.1 and it will crash on NT 6.1. ntdll hosts the system call entry and exit code. The kernel-user callback dispatcher code. The thread start function which the kernel knows the address of. The user exception dispatcher. The user APC handler. I could go on, but I won't.
I don't see why you're trying to "bundle" these DLLs with your program. There is no way a Windows install won't have these DLLs. And that's ZERO chance for ntdll.dll since I don't see how without the session manager and CSR you are going to run your program in the first place.
I find the idea to "bundle" system DLL as not a good idea.
First of all it is illegal to redistribute this DLLs together with your application. Seconds you should understand that a DLL can create some global objects and the usage of two copies of the same DLL (vtdll.dll and ntdll.dll) can not work. You don't wrote how you modified imports of the dlls. If you do it on the disk it is illegal and moreover it break the signature of the files (open file properties of any of the dlls and look at "Digital Signatures" tab).
If you do want to experiment with different copies of system dlls you can better use DLL redirection (see http://msdn.microsoft.com/en-us/library/ms682600.aspx) through creating of files with the name myapp.exe.local where myapp.exe is the name of your application. It can be required to delete some entries from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\KnownDLLs to do this. You should understand that your computer will run slowly after this and I recommend to make such experiments better inside a virtual machine which you can easy restore if it will be no more booted.
Thanks for the information. It helped me to do a research on it.
I am not bundling the dlls for my own application. I am doing it for existing applications to provide a windows cross platform independence solution.
I tried the dll redirection technique which you have posted, with all applications.
It works well with all dlls except NTdll and User32.dll
User32.dll:
It loads user32.dll from local space only and not kernel space. I confirmed it. But on executing its instructions, it results in the null address access exception (c0000005) with fault module name StackHash_5964
ntdll:
The application on booting, it loads ntdll from system32 and again loads ntdll from local space, which may cause the error as you said (global object sharing violation)
This happens only for ntdll and not for user32.dll.
Is there any way we can make load ntdll once(only form local space) and avoid the errors caused by user32.dll in local space.
I tried the references sent by you and here are the results.
User32.dll
I couldnot build user32.dll having these below functions.
IsThreadDesktopComposited = user33.IsThreadDesktopComposited,
User32InitializeImmEntry = user33.User32InitializeImmEntry
It produces a linker error (Unreolved external symbol "IsThreadDesktopComposited")
Hence i left 100 such functions out of 800 functions in user32.dll. The DLL was built finally.
I then placed the dll in local space along with user33.dll. On running the application, it says the 100 missed functions procedure entry points are not found.
Ntdll.dll
I tried removing known dlls. But its inacccesible for modify or delete operations. I could just read. I am the admin and ran regedit as administrator.
Is it possible to do such implementatipons for ntdll or user32.dll.
I guess, am coming with repeated times.
Thanks for all your help.
But, If you have any other ways or any suggestions you can make, that would be grateful
