WIN3 STYLE FILE OPEN DIALOG - FOPEN v1.1
The archive should include the following files:
FOPEN.INF This file.
FOPEN.MAK Project MAK.
FOPEN.BAS Globals.
FOPEN.FRM Win3 Style File Open dialog.
FOPDEMO.FRM Form to demo FOPEN
To see a demo, load FOPEN.MAK which requires FOPEN.BAS, FOPEN.FRM and
FOPDEMO.FRM and run it.
If you want to use FOPEN in your programs, copy the contents of FOPEN.BAS
to your Global file and include FOPEN.FRM in your project. FOPDEMO isn't
needed. Your VB WinApp can use the globals FullName, TheFileName, ThePath,
and ThePattern to pass information between the Parent and FOPEN. The global
FormTitle sets a title for FOPEN.FRM.
The source code is commented and should answer most of your questions, but
if it doesn't you may reach me via CIS-MAIL at 73667,1755. When you're
comfortable using FOPEN delete the comments. Some routines are borrowed
from the Visual Basic Programmer's Guide and cardfile.bas.
FOPEN is free but if you make any improvements (hint: it can be changed to
act as both a File Open and File Save As dialog) please CIS-MAIL me a copy.
Changes since FOPEN version 1.0:
1. Added EM_LIMITTEXT to FOPEN's Text1 textbox to limit entries
to 127 characters. This is more than generous.
2. Corrected the OfStruct type definitions for OpenFile.
3. Changed Msg declares to conform with Windows API's
format, e.g. WM_USER + 5
4. Removed the MsgBox warning when changing to an invalid
subdirectory with ChangeDir. Win3 style File Open simply
highlights the text to bring it to the user's attention. If
you want the warning, simply put it back.
5. Added a few more comments.
Enjoy,
