I am trying to develop a small application which must interact with a very old version of access and pull the data out. We have a solution already in powershell but we want to move away from powershell and get it in C#
I think I have code that should work theoretically, but there's one setback, it must be run in 32-bit mode due to the age of the access version I'm working with. When I run my app, there are no exceptions, I simply get a message in my debug console that says:
The Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
The powershell has a requirement that it must be run in 32-bit powershell and after researching the above message I believe my application must also be run in 32-bit mode. I have also settled on using OLEDB to access the file, just as the powershell does, further adding to my assumption
I primarily use VSCode to develop here, but I am not above installing regular Visual Studio if necessary
I installed the 32-bit VSCode and ran my application there but I got the same message
How can I fix this?

Since I mostly develop Web, using nginx, PHP and MySQL, I have ported my WebDev-environment entirely to WSL2.
Since performance is very important, all my web-related projects reside on the WSL2-vhdx file /home/user/Projects/Web. In WSL2 I've installed all my necessary tools for a nice and neat Linux-like experience, Docker, GIT, etc.. This combined with VSCode remote integration works very well.
Now, I'm digging into building Flutter-Apps, and my Flutter-environment is installed on the Windows side. My Flutter-related projects reside on D:\Projects\Flutter which is a partition, and NOT USED in WSL2 in any way. Building Flutter-apps with flutter-windows-sdk and VSCode works neatly.
But, the problem is: Now I've my project files scattered all across my computer. Web-stuff in a WSL2-vhdx-file and Flutter-stuff on the D-partition.
Is there a way to build flutter-apps with Flutter, while having the project-files stored on a WSL2-vhdx-file, in combination with VSCode-remote and an Android-emulator?
I tried creating a test Flutter-project on the \\wsl$ network mount, which didn't work.
Moving my web-related project files to the D:\ partition of Windows is no option, since the I/O mounts in WSL2 are extremely slow.
I got it working, reliably with adb connect 192.168.xxx

I'm assuming (based on the mention of VS Code Remoting) that you want to run the extension in WSL. I haven't tried that specifically, but I have run Flutter inside WSL and also connected a VS Code Remoting session to an Android emulator in the cloud, so I would expect this to work.
You'll need to make sure you set up the Flutter SDK inside WSL (so you can run flutter commands inside WSL - it should be the Linux version of the Flutter SDK and not the Windows one if you're using the zip).
To have your emulator show up in flutter devices from inside WSL, you will likely need to run adb tcpip 5555 from the Windows side (this means you need an Android SDK in Windows) - this will tell your phone to listen on TCP port 5555. Then you'll need to run adb connect [phone ip]:5555 from inside WSL (this means you'll need an Android SDK in Linux). If all goes well, the phone should then show up in adb devices and also be picked up by the device selector in VS Code.
I tried creating a test Flutter-project on the \wsl$ network mount, which didn't work.
It's not clear what went wrong here, though my first guess would be that maybe the UNC path isn't supported - if you map a drive letter to it does it make a difference?
While this isn't an officially supported setup, feel free to raise issues in the Dart-Code repository on GitHub with any issues you have. It's not a priority, but I would like for VS Code Remoting (including WSL and Docker) to generally work for Dart and Flutter dev.
Anytime you're crossing/sharing the file-system boundary from windows to wsl you're paying a massive cost in speed/time.
With the setup you've described I'd consider trying to self-host the browser based VSCode.dev inside wsl - checkout details instructions here: https://medium.com/geekculture/3-steps-to-code-from-anywhere-45401247f479
Personally I've settled on running VSCode and docker inside a Linux VM on Windows, and have a 96% time saving in things like running up a server and watching code for changes making this setup my preferred way now.
The standardisation of devcontainer.json and being able to use github codespaces if you're away from your normal dev machine make this whole setup a pleasure to use.

I have a rather large application built in visual studio which runs in x86 and have recently had a need to integrate a library which is only built in x64. Is there a way to utilize an x64 dependency in x86 mode or do I need to build a seperate application, somehow call it then maybe pass the data back to the parent application via a socket or something???? Any Suggestions?
I resolved this issue by creating a second application to run in 64 and set up listeners for console output and error output in order to pass data back
I've developed a OSGi application on my windows machine that is just lovely. How ever I need it to run on my Linux server and this is where I run into problems.
My application has no GUI. It simple works with a console and is command line driven.
My first attempt at deployment I built a product based on my existing run target. It exported fine to a Windows .exe so I added the required delta packs for Linux. The problem with this is it has only two options Linux (GTK) and Linux (MOTIF). My linux server runs on CentOS with no GUI as it is a hosted machine so when I try and deploy it I get a segmentation fault.
I have been searching around as to what to do but I'm not coming up with any answers.
Any help would be much appreciated. I have been banging my head on this one for over a week
Cheers
The google keyword you need is 'xvfb' - it acts like an X server, but ignores everything sent to it, so you don't need any graphics hardware. Try firing that up (make sure you set DISPLAY appropriately).
A cleaner solution would be to figure out why the library is demanding an X server if it works without - perhaps you could update the question with more details.
On a MacBook Pro running Windows 7 in Parallels 7, I need to run a Unix Executable File on the Mac side via a command line invocation on the Windows side. In Windows Explorer, I can use Open on Mac, but I need a way to do this via a batch file or anything else that can be expressed on a command line. I was hoping that Parallels Tools might have a command that can do this, but I can't find anything.
This seems like it should be pretty straightforward, but my searches have turned up nothing.
I also tried creating an alias on the Mac side, which I added to my Applications folder. I was hoping that it would appear in Start > All Programs > Parallels Shared Applications, which might allow me to access it with a batch file. However, I don't see it. I'm not sure what it takes to add new entries to Parallels Shared Applications. Maybe a reboot would do it, but I have not tried that yet.
Thanks for any advice.
It seems like the Platypus app might be able to help with this. It wraps a shell script into a Mac App. Unfortunately I can't get Parallels to provide access to the Platypus generated app the same way it provides access to the other Mac apps.
Is there a way to programmatically install device driver silently without cat file and without connecting the device on Windows Xp?
I'm using DriverPackageInstall function from Windows Driver Kit. And I can install driver only if device is attached. In other case I get an error: ERROR_NO_SUCH_DEVINST. But that method works fine with Windows Vista.
Another problem is warning dialog that asks user to continue or stop installation because cat file is missing . It shows on both OSes.
Any ideas?
You're not going to get past the signing prompt, as this is baked pretty far into windows, but there is a tool in the DDK called devinst that works well for device installations.
There's Source Code included with it.
The only way to avoid any UI interaction caused by your driver being unsigned is to hackishly preinstall the driver by modifying the registry directly.
Yes, it can be done. You'd have to modify the ACLs on the HKLM\System\CurrentControlSet\Enum registry key run as SYSTEM (by installing yourself as a service or using Sysinternals psexec -s), and add all the registry keys which Windows device installation would usually add - on your own. This will only work if you can predict precisely what your device's Device Instance ID would be -- e.g. in case of a USB device, the precise port it'd be connected to etc.
This is hacky, but the result would be the device being essentially "preinstalled". It'll be a lot of work, and it'll break on Windows Vista.
Microsoft really wants you to go the WHQL way on Windows XP, sorry :(
