I try to create a new text style when working on client's drawings.
Here is my code
(command "._-style" "Arial" "arial.ttf" "0.0" "1.0" "0.0" "No" "No")
Then I have an error message:
Command: (command "._-style" "Arial" "arial.ttf" "0.0" "1.0" "0.0" "No" "No")
._-style Enter name of text style or [?] <STANDARD>: Arial
New style.
Specify full font name or font filename (TTF or SHX) <txt>: arial.ttf
Font file doesn't exist.
Command: 0.0 Unknown command "0". Press F1 for help.
Command: 1.0 Unknown command "0". Press F1 for help.
Command: 0.0 Unknown command "0". Press F1 for help.
Command: No Unknown command "NO". Press F1 for help.
Command: No Unknown command "NO". Press F1 for help.
Command: nil
AFAIK, all "ttf" fonts are resided in "c:/windows/fonts" directory.
I then explore the font foder & found a "arial_2.ttf" instead of "arial.ttf".
The strange thing is that the following returns "c:\\windows\\fonts\\arial.ttf".
(findfile "c:\\windows\\fonts\\arial.ttf")
I then did a couple of searches by using "findfile" method again & these are found
"c:\\windows\\fonts\\arial_0.ttf"
"c:\\windows\\fonts\\arial_1.ttf"
"c:\\windows\\fonts\\arial_2.ttf"
"c:\\windows\\fonts\\arial_3.ttf"
"c:\\windows\\fonts\\arial_4.ttf"
"c:\\windows\\fonts\\arial_5.ttf"
"c:\\windows\\fonts\\arial_6.ttf"
"c:\\windows\\fonts\\arial_7.ttf"
"c:\\windows\\fonts\\arial_8.ttf"
"c:\\windows\\fonts\\arial_9.ttf"
These font files do not exist in the "c:/windows/fonts" directory in fact.
Of course, I can rename the file name of "arial_2.ttf" to the original "arial.ttf".
But now my question is in the code how to check if the "arial.ttf" exists before creating the "arial" text style?
Thanks for your help.

Just to demonstrate a possible idea - not really a practical solution:
(defun CreateTextStyle ( style font / result )
(defun _GetSpecialFolder ( name / wshShell specialFolders result )
; MP
(vl-catch-all-apply
'(lambda ( )
(setq
wshShell (vlax-create-object "WScript.Shell")
specialFolders (vlax-get wshShell 'SpecialFolders)
result (vlax-invoke specialFolders 'Item name)
)
)
)
(if specialFolders (vlax-release-object specialFolders))
(if wshShell (vlax-release-object wshShell))
result
)
(if (setq font (findfile (strcat (_GetSpecialFolder "Fonts") "\\" font)))
(vla-put-Fontfile
(setq result
(vla-Add
(vla-get-TextStyles
(vla-get-ActiveDocument (vlax-get-acad-object))
)
style
)
)
font
)
)
result
)
e.g.:
(CreateTextStyle "NewStyle" "Arial.ttf")
Note that if the Style specified exists, the font file for that style will be changed accordingly, else the Style will be created. Either way, if the fontfile is found, the Text Style will be returned.

Thanks Lee.
Hope I haven't misunderstood what you explained.
Actually I can create a new style with any name.
In this case I am not worrying the style name but the font file to be used.
As I described previously, the code can lie by returning "c:\\windows\\fonts\\arial.ttf" when I use "findfile" method,
because the "arial.ttf" doesn't exist instead of "arial_2.ttf".
To ensure the font does exist, I need to put a checking function before I create the new style.
-
I wasn't pertaining to the name, that was just a convenience of the code, rather that this...
(setq font (findfile (strcat (_GetSpecialFolder "Fonts") "\\" font)))
...works fine for me :-)
-
Sorry, maybe I have not expained clearly.
I want the code returning a result something like "arial.ttf is not found" if the "arial.ttf" does not exist in the "c:/windows/fonts" directory.
-
Well, arial.ttf should exist in the Font folder as arial.ttf ... Windows may report it as a different name since it is in a special folder (I don't know why they ever thought that was a good idea) ...
Have you tried using the fully qualified path to the font?
(command "._-style" "Arial" "c:\\windows\\fonts\\arial.ttf" "0.0" "1.0" "0.0" "No" "No")

Yes, I have tried & had the same result (the messgae: the "arial.ttf" doesn't exist.)

You could easily add an 'else' expression printing a message of that nature to my current code if need be - my question would be: does my code work for you? i.e. does it return a TextStyle object?
-
Sorry, Lee.
I tried but it doesn't work.

Hi...
Just to get registered Font Files (at least in Windows XP); after that you can check if your choice is a member of them.
(defun Get_TTFs (/ RegKey RegTTF TtfFil)
(setq RegKey "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Fonts"
RegTTF (vl-registry-descendents RegKey "")
)
(foreach n RegTTF
(setq TtfFil (cons (vl-registry-read RegKey n) TtfFil))
)
(reverse TtfFil)
)
Regards from Spain :-).

Thanks to Lee, again.
Here is what I got:
#<VLA-OBJECT IAcadTextStyle 000000002b774a68>
-
Thanks to Pepe.
Your code returns all fonts in the "fonts" folder.
It looks nice.
But I also need a filter to show only the 'arial.ttf".
-
Thanks, Alan.
Your code can return the family of "arial" fonts.
It looks a lot better.
How to improve the filter to show only "arial.ttf" if it exists?
Thanks again.

I will come back to your reply.

...
Now I modify this line:
(_filter (GetTTFs) "*ARIAL*")
to
(_filter (GetTTFs) "Arial (TrueType)")
It looks fine.
It returns:
(("Arial (TrueType)" . "arial.ttf"))
Am I right?
The next question is how to subtract the "arial.ttf" from above line?
Then I can write something like:
(setq ArialFont ...) ;[color=red]need help in this line[/color]
(if (eq ArialFont "arial.ttf")
...

But I don't understand the point of what you're trying to accomplish. You aren't wanting a list, you are wanting one particular font, but you are basically getting out what you are putting into the sub.

I am going to create a new text style & this is alright to me.
But I found the problem which the font file name has been changed & the code return an error message, as I mensioned before.
So I want to do something like this:
1) Check if the normal font name exists in the windows registry.
2) If the font is found, then create the text style, otherwise give user a warning message.

Updated mine to give a 'warning message':
(defun CreateTextStyle ( style font / result fontfile )
(defun _GetSpecialFolder ( name / wshShell specialFolders result )
; MP
(vl-catch-all-apply
'(lambda ( )
(setq
wshShell (vlax-create-object "WScript.Shell")
specialFolders (vlax-get wshShell 'SpecialFolders)
result (vlax-invoke specialFolders 'Item name)
)
)
)
(if specialFolders (vlax-release-object specialFolders))
(if wshShell (vlax-release-object wshShell))
result
)
(if (setq fontfile (findfile (strcat (_GetSpecialFolder "Fonts") "\\" font)))
(vla-put-Fontfile
(setq result
(vla-Add

(vla-get-ActiveDocument (vlax-get-acad-object))

(princ (strcat "\n** " font " not found **"))

The font file has already been assigned to the TextStyle at that point (using vla-put-fontfile in the code) - if you check the newly created TextStyle after running the code, is the Font assigned correctly?
This line:
(setq fontfile (findfile (strcat (_GetSpecialFolder "Fonts") "\\" font)))
Constructs the FontFile path.

Agreed. I guess I had the fun blinders on. Don't listen to me.
I was just trying to remember that sysvar.

Sorry, Lee.
(setq fontfile (findfile (strcat (_GetSpecialFolder "Fonts") "\\" font)))
It is much the same as the following mensioned previously:
Because the they may return a fake result.
(findfile "c:\\windows\\fonts\\arial.ttf")
I have just read your latest post & check this one gives the same result as above:
(findfile (strcat (getenv "windir") "\\fonts\\arial.ttf"))
I was wondering if there is a way to check the font file name.
Because the "fildfile" lines above may return a fake result as menstioned.
I discuss this issue because the font file name could be changed in some cases.

I'm just a little puzzled since the result you posted from running my previous code (the first post) indicated that the font assignment was successful. Which raises the question: What font was assigned to the new TextStyle?

It's a wacky mystery! :lol:

I have already renamed the "arial_6.ttf" to the original "arial.ttf" in my system.
By continuing the tests I use the "ariali_5.ttf" (my "ariali.ttf" name was changed as well).

Alan, did you read my post #34?

Will it return a lowercase value if two line were:

...
ttf
Instead of
(strcase (vl-registry-read reg x))
...
(strcase ttf)

(strcase <String> T) would, but it's not to set the case, but to have the same case for comparison purposes. Unaltered, each could return any case.
eg.
(eq "dog" DOG") => nil
(eq "DOG" "DOG") => T
(eq (strcase "dog") (strcase "Dog")) => T
In this situation, the case is irrelevant, so I'll just capitalize each for easy comparison.
However, dont' take my word for it. Dissect the routine, step-by-step and see what actually happens.
