How to get pointers to variables and file location

[Benzsoft]

Hai,
Please clear my following doubts.
1.Is there any VB 6 functions or WinAPI functions to return pointers
to variables & file location? Does programming with pointers work well with
VB 6?
2.What type of files can be opened and accessed through VB6 during runtime?
3.For a spell checking program in VB, which dictionary file formats are
best, that can be used in VB.
4.What type of files are .HSE.

Please send replies to the above queries.

"Benzsoft" -

1. VarPtr() gives you a pointer to most simple variable types, except strings
for which you use StrPtr(), and objects for which you use ObjPtr().
As for "pointer to file location" - are you talking about the exact cylinder/track
location - sounds rather hardcore!
As for programming with pointers: there are no pointer types as in C or Pascal.
You have to treat all pointers in Win32 as simply type Long. You will also
have to do dereferencing using the CopyMemory() function, and sufficient
memory.
2. VB will open any file, assuming the current user has file permissions
set up correctly.
3. No idea - you might want to follow the "Calling MS Office Spell Checker
from VB/VBScript" thread in this group.
4. No idea.
