Hi All,

I am working on project that involves adding/removing fonts in Windows\Fonts, I already tried the follwing steps programmatically:

1. Delete from registry

regkey = Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts", True)

regkey.DeleteValue(s)

2. Delete from C:\Windows\Fonts\

Above steps does not work, it only removes the entry of the font in the registry but I was not able to delete the fonts in C:\Windows\Fonts\

Any Idea how to solve this problem of mine? any help will surely be appreciated Smile | :)

I got it from an article in the web, I forget exactly where. Can you show me some codes on how to do this?

Thanks!

Thanks/Regards

I tried calling the API you suggested, but it's still not working Frown | :(

Please help me, can you show me some codes? I am trying to delete Windows\Fonts not font resources in a project but the actual fonts in the C:\windows\fonts.

Thanks

Thanks/Regards
Sidney

If you can't provide any more specific information than "it's still not working" I am done helping you. On the link I previously gave you... at the bottom there is a "See Also" section with a "Fonts and Text Overview" link. I strongly suggest you read the documentation.

I also suggest you read the top message in this forum titled "How to get an answer to your question", pay attention to item #2.

Hi,

I already read the documentation, sorry if you misunderstood my question that you became a "Mind Reader". Fonts and Text Overview are for project resources I don't know if you are aware of the topic I have posted "Add/Remove Windows Fonts Programmatically" what I am trying to do is actually removing fonts from the Windows Fonts table and not those that I want to add in my project and remove afterwards I am done using it.

To explain further here is what my project requirements are:

1. A watch folder in a network drive has been setup where users can add and remove fonts for global use.
2. My application is installed in multiple work stations inside Local Areak Network and will be watching #1, if there are fonts in the watch folder that does not exist in their local machine, my application should add it (this part is already working perfectly fine)

If somebody delete fonts in the watch folder, what my application would do is send out a notification to all users that a font has been deleted from the watch folder "AND IT SHOULD DELETE THE LOCAL MACHINE FONT (Windows Font)" as well.

I hope that by giving this requirements you'll understand what I am trying to achive and that what you suggested is totally out of line co'z "Fonts and Text" focus on your Visual Studio Project Resources and not the Windows Font Environtment.

Thanks/Regards

I don't know where you learned to read but you need a refresher course

"The RemoveFontResource function removes the fonts in the specified file from the system font table."

batanglasang wrote:

Depends on your definition of "working fine". Based on your post I doubt you used AddFontResource to do that so I would not consider it "working fine".

I didn't misunderstand anything. You did not provide any information until your last post and as I stated before, it's to late, I have lost interest in helping you.

use .dll problem

I am not so familiar with using .dll.
I want to realize the following:

I have a .exe project. From this I want to call some newly added .dll functions. For the .exe project, I just use reflection to call the .dll funcitons by their function names. Now the problem is that how the .exe project can take into account the newly added .dll functions?
For a .sln project, of course I can add any .dll by using "add reference". But once it is compliled into .exe, how include then?

thanks.

The dll "walks with u"

if the dll can be decompiled and u can open it with VS and see it's Content

Why all The mess
Why not just using the : SqlDataAdaptor

i've been using OdbcDataAdaptor, & OledbDataadaptor

and it's easy
no 100 Line codes, but half and even less

Try it

It's actually creates a conector betwen your DB and your Data Grid
