wierd UpperCase/LowerCase behavior with MKDIR

[Mike Trader]

I am trying to create a directory with an all uppercase name.
I cant do it with MKDIR. If all the charadters in the name are
uppercase then the directory is made with the first character
uppercase and the rest lowercase.

However, If the LAST character in the dir name is lowercase, then
the rest of the name WILL be uppercase !!??

I am using:
IF FldrExistsFlag = 0 THEN MKDIR ProgPathStr + SymbStr + PrefixStr

where SymbStr and PrefixStr are all Uppercase

and

CALL GETMODULEFILENAME(BYVAL 0&, TmpAsciiz, SIZEOF(TmpAsciiz))
ProgPathStr = LEFT$(TmpAsciiz, INSTR(-1, TmpAsciiz, "\"))

Is this a windoze thing or a MKDIR "undocumented feature"

What length are these file names? Windows implementation of mixed-case naming definitely has some quirks, but this could be a simple matter of 8.3 vs LFN naming.

I'm 99.99999% sure that internally, PowerBASIC passes the file name to Windows without "adjusting" it in any way.

The FOLDER (or directory) names are quite short for example

ES_01H_FUT
DK_01M_OPT
AC_01Z

In front of them is the path:

C:\PBDLL60\OmegaResearch\Data&Apps\

I have experimented more and it turns out that it only takes
ONE lower case character to produce the correct case throughout
the whole name.
That character can be anywhere in the name!

I wish I could be more creative with the names, but i need them
to be all uppercase.

Perhaps I could MKDIR then rename it and get it all uppercase that way?

Both creates folders with all upper_case name
WIN/98 WIN/ME WIN/NT WIN2000

#Include "Win32api.inc"
Function PbMain()As Long
  D$="C:\TESTING_UPPERCASE_DIRECTORY"
  CreateDirectory ByVal StrPtr(D$),ByVal %NULL
  MKDIR "C:\TESTING_ANOTHER_UPPERCASE"
End Function

Disregarding the actual mixed-case format the file name takes for a moment, is there a specific reason you need the names to be in a specific case format?

That is, when querying the name with DIR$ or OPEN, etc, you can specify the name capitalized or lowercase or mixed and the file will be handled by Windows correctly.

The only time you'll have any problems is if you are testing the filename without converting it to a specific case, ie:

IF DIR$("path\TheDataFile.dat") = "THEDATAFILE.DAT" THEN...

...may fail depending on the capitalization of the returned name, but if you convert the case, thus:

IF UCASE$(DIR$("path\TheDataFile.dat")) = "THEDATAFILE.DAT" THEN...

...then it will compare/match correctly since the case becomes irrelevent.

In WIN/NT there are a setting (Properties Folder) "Allow all uppercase directory names"

Right on, Fred. By default, Windows shows all-uppercase names as mixed case--
one of those bad old historical quirks dating from Windows 95. Many versions
of Windows have a setting in Folder Options / View that allows you to turn
off this case mangling.

Lance,
I know what you are saying.
The reason I need it all uppercase is cos im trying to match
the output of an old DrOS program. It manages to create all
uppercase FOLDER names. I dont want to get questions from my users
"why are your folder Names different?"

Edwin. I use Win98SE. When I finally pluck up the courage to spend
a week buying new cards and installing drivers by hand I will switch
to the promising win2k.

Hi,

As Fred and Tom pointed out, there's a setting controling this behaviour.
This link describes the details.... http://www.winguides.com/registry/display.php/768/

Yeah I foubd it thx Fred and Tom

Is there a way to set that from my app?

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
Value Name: "DontPrettyPath"
Value Data: (0 = adjust caps, 1 = show caps {don't adjust the capitalization}))

This is a "global" setting for the PC, so adjusting this may cause other side-effects, such as upset Windows users whose other filenames are now appearing differently!

If I were you, I'd make the use of this purely optional...

Mike,

doesn't show ? works fine from here, try : http://www.winguides.com/registry/
Then select the "Tips and Tricks" Category,
Then about mid-page, there's a link to : "Show File and Folder Names Using the Correct Case"

summary :
Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
Value Name: DontPrettyPath
Data Type: REG_DWORD (DWORD Value)
Value Data: (0 = adjust caps, 1 = show caps)

To do it from Your app You need to use some registry API's, do a search here...

Please note that Windows is not changing the actual case of the directory.
It's only changing how the directory is displayed by, say, Windows Explorer.
Your own app remains free to display filespecs in any way it likes. Since
filespecs are (usually) not case-sensitive in Windows, of course, any
filespecs passed to your program may not be the "real" case: if you need to
retrieve the exact case as stored on disk, you'll need to use FindFirstFile
or some similar method.
