VB3/4 control problem
in [Visual Basic]
|
From: Tym on 23 May 2006 15:19 I have been tasked with re-developing an old VB3 app. I have vb4,6 and 2005.net I do not have the original source code (long story) but have got a decompiler which has created the necessary source files. Problem 1 - the .frm files are binary. VB6 can't read them - but vb4(16 bit) can. The idea is to get vb4 to create "proper" forms I can then load into vb6 - don't know if this will work. If not - I'll have to develope it in VB4 (sigh) The program uses an old 2.? DAO to access an access 2 .mdb database so I am reluctant to migrate this to ADO.NET - thinking of leaving it with DAO on vb6 - its what I know best! Problem 2 - the forms appear to have custom controls on them VBX.SSFrame and the like. This is preventing the forms from loading properly. IS ther a way I can recreate these, or download something similar from somewhere and rename them??? I've obtained a copy of sswin.dll, but can't register it. Probably the fact the regsvr32 can register 16 bit dlls??? DOn't know if that's realted to the VBX.ss??? controls....? Is there a way round this as I don't like to let customers down.

Is there a way round this as I don't like to let customers down. Unfortunately the original VBX files will be required, however they are not COM controls and do not need to be registered. It may be possible to replace their functionality with built-in controls (or third-party controls) if you can identify what they do. You may want to post a list of the files being used by the project. Paul ~~~~ Microsoft MVP (Visual Basic)

Hmm... When I open the MAK file, in vb4, I am asked to upgrade the following custom controls in the project to their newer versions: CMDIALOG.VBX CRYSTAL.VBX MSCOMM.VBX MSMASKED.VBX THREED.VBX The only one of these I have from the original archive is MSCOMM.VBX. I have sourced the others though... not sure which directory to put them in though - windows\system seems logical to me. Then I get "License fil for custom control not found..." for MSCOMM, Masked edit, Sheridan 3-D Widgets/1. When asked If I want to save the forms as VB4 I click OK FOR ALL Then I get "Custom control 'VBX.SSFrame' not found" etc etc... However...... If I start a NEW project and add the controls I can design with them... Odd... I'm trying to start a blank projet and add the forms in manually, but the VBX.SSxxxxx is still causing a problem. Is this to do with the controls or sswin.dll? Tym ~There's no place like 127.0.0.1~

Yeah, put the 16-bit ones there, and the 32-bit ones in \system32 > Then I get > > "License fil for custom control not found..." for MSCOMM, Masked edit, > Sheridan 3-D Widgets/1. http://www.google.com/search?q=%22License+file+for+custom+control+not+found%22 -- Working without a .NET? http://classicvb.org/

DAO to access an access 2 .mdb database so I am reluctant to migrate this to ADO.NET - thinking of leaving it with DAO on vb6 - its what I know best!" There is nothing wrong with sticking to DAO for an MSAccess database - there are in fact advantages - especially if it is local. Are you going to upgrade the MSAccess2 mdb files to something newer? There is one cravat if you leave them as Jet2. Writing to or sharing a Jet 2 database with other versions of the Jet engine at the same time is practically guaranteed to corrupt the database. (Actually there are only a few small problem datatypes - so you might luck out - but few seldom do. <g>) -ralph |
