Jag #1 / 3	Visual Basic 3.0 to Visual Basic 6.0 Hi, We have an application in VB 3.0 which we want to upgrade to VB 6.0. Can anybody give me the list of differences between VB 3.0 and VB 6.0? Any web site address with the above information will also help a lot. Thank you in advance. Jag

Bob #2 / 3	Visual Basic 3.0 to Visual Basic 6.0 The way I remember it the two biggest problems I had moving from VB3 16 bit to VB4 32 bit were: 1. changes in internal VB function definitions, i.e. many Integers have to change to Longs 2. API calls are different, including some 16 bit functions that are not available at all in the 32 bit world. Note that VB6 will not open VB3 files. I am pretty sure the easiest migration path is going to be to upgrade your app to VB4 32 bit, then upgrade that to VB6. Going from VB3 to VB4 32 will be the most work, moving to VB6 from VB4 should take a lot less work. The VB4 CD had articles about problems with converting VB3 apps to VB4 32 bit apps, if you have VB4 look in the help. If you don't have VB4, buy it.

RobSmit #3 / 3	Visual Basic 3.0 to Visual Basic 6.0 VB6 will open VB3 files if they are saved as text, not as binary. I don't think going VB3->VB6 will be any harder than VB3->VB4/32->VB6 (i.e. it will be equally painful!) VBX Controls will only get converted if you have both the VBX and 32-bit OCX versions correctly installed on your system. Crescent Software used to have a VB3 to VB4 upgrade wizard downloadable from their web site http://www.progress.com/crescent - I don't know whether it's still available. -- RobSmith : The way I remember it the two biggest problems I had moving from VB3 16 : bit to VB4 32 bit were: : 1. changes in internal VB function definitions, i.e. many Integers : have to change to Longs : 2.
