VB4 to VB5 howto (a newbie)
Hi everyone,
I recently made a career move from VFP to VB and my first project is to
migrate an in-house VB4 application onto a VB5 application.
The current application has the following specifications:
OS
Windows NT 4.0
App (All 16-bit)
1. VB4
2. Crystal Reports
3. VBTools VBXs
4. WINAPI calls
5. Access 2.0 database
6. Data access using Jet engine DAO 2.0
7. Using secured database SystemDB (Access 2.0)
Goals - All 32-bit
My initial evaluations on the migrations including
* Convert all crystal reports to 32-bit
* Upgrade 16-bit VBTools VBXs to 32-bit OLETools
* 16-bit WINAPI calls need to modified because of different variable types
in 32-bit
WINAPIs
* Convert Access 2.0 to Access 7.0
* Using Jet engine DAO 3.5 for data access
* Convert secured database SystemDB to Access 7.0
My problems are:
* The clients using this application are in a different city and the
upgrade will be
transferred via eletronic BBS instead of on-site migration.
* Anything that I need to be aware of on the Crystal report conversion?
* Where can I obtain OLETools and is the conversion going to be seamless?
* The Access 2.0 SystemDB is using an .INI file for security, but the
32-bit
SystemDB retrieves the information from the Windows registry instead of
the
INI file. Is that true? How do I implement it by using WINAPI32 calls?
How do
I update the registry to register the SystemDB and retrieve the info for
user login
programmatically?
Any ideas or suggestions will be highly appreciated and please direct your
response
