Windows 10: How does CFile::Open LPCTSTR lpszFileName, UINT nOpenFlags CFileException* pError assigns...

I have analyzed an older application and tracing an error to this MFC class function. In some versions of Windows 10 and earlier version of Windows this method worked normally however newer build of Windows 10 and Windows 11 have generated this error. The file I am loading is a text file, and I have tried to changed folder and file permission

Microsoft Teams can not open assignment page suddenly.

Hi Вэньжуй,



I go through the post carefully, based on the description, it seems that you cannot open Assignment from any devices. As for the issue, here are some suggestions:

1. To check if the issue related to your network environment, please connect to another network and check if you can open the assignments normally. If you are using antivirus software, please also turn off them temporarily and check the result.
   
2. Check if you can open assignments from Teams for the web at https://teams.microsoft.com
   

If you still cannot open assignments, could you please share information below with us?

1. Did you change anything before the issue?
   
2. Do you get any error messages?
   
3. Do your classmates get the same issue?
   

Regards,

Clark

 

Context Menu - Open With (Windows Suggested List)

OS: Windows 10 Pro x64 22H2 Diagram 'A' shows Windows' suggested programs Diagram 'B' shows the extended list I have been trying to edit the context menu's "Open with" list of Windows' suggested programs for the .mp3 extension. I'm not talking about the extended list, but rather the programs that first appear 'before' the "choose another app" option. If you look at Diagram 'A' you will see the preliminary list generated by Windows, this is the list I am looking to modify. I have an .mp3 editor named Goldwave that I use for editing audio files, however, I do not want to change the preliminary program Windows uses to open .mp3s. My .mp3s should remain assigned to Winamp Player. Any help would be greatly appreciated.

 

Drive letters are not available for assigning to unallocated space

Hello Sjoerd,



Thank you for writing to Microsoft Community Forums.



The reason the drive letters are not available to assign are because they might have been assigned to devices which are removed or hidden. I suggest you to check for any hidden devices and remove them to assign the missing drive letters.



Follow the steps mentioned below to check for the hidden or removed devices.

1. Press Windows key + R. This will open
   Run. Alternatively, you can go to Start and search for Run.
   
2. In Run dialog box, type
   devmgmt.msc and hit enter.
   
3. Click on the view tab at the top left hand corner.
   
4. Now select View hidden devices.
   
5. Now look for the hidden devices under storage volumes and
   portable devices.
   
6. Right click on the hidden devices and click on
   uninstall.
   
7. Restart the PC.
   

After restarting the PC, try assigning the drive letter to the unallocated drive and check if the drive letters D, E, F, G, and H appears.



Hope it helps.
