Getting Visual Basic 6 To Work In Windows 7
Why You Want VB6 To Work In The Windows 7 64 Bit Environment?
If you can't develop with Visual Basic 6 in the 64 bit Windows 7 environment, you probably will not be able to use VB 6 for development in future versions of 64-bit Windows. If you can't develop a 64-bit Windows environment, you will be stuck in the quirky XP Mode environment. There are rumors of a 32-bit Windows 8 environment that might accommodate programs that can't move to the 64 bit environment. Do you really want to use a 32-bit Windows 8 (compatibility) operating system when you can use a state-of-the-art 64-bit Windows 8 operating system for software development?
What Are The 64-bit, 32-bit and 16-bit Problems?
With some modifications, you should be able develop with VB6 in the newer Windows 64-bit operating systems. In general, the problems getting to a 64-bit operating system with VB 6 are 16-bit issues. Basically, Visual Basic 6 is a 32-bit system that can be used to develop 32-bit programs. 32-bit programs run in the Windows 64-bit environment and are rumored to have the capability of working with future Microsoft 64-bit operating systems.
Here are some of the issues that you will face migrating Visual Basic 6 to a Windows 7 64-bit system:
If you can't develop with VB 6 in Windows 7, you may be looking at either rewriting the application to work with VB.Net or abandoning the application entirely. Either alternative may prove too expensive to consider.
The Third Party ActiveX Component Nightmare
Your installation CD might not work! This is an easy test to see if you're in trouble. Put the third-party ActiveX component CD into your CD drive. If it works, your problem is probably solved. This is what you do not want to see: Unsupported 16 Bit Application – The program or feature "<probably setup.exe something>" cannot start or run due to incompatibility with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available.
Other than your screwed, what does this mean? In plain English, this means that the install routine is a 16 bit application. This is not unusual, since the third-party vendor was distributing both 16-bit and 32-bit controls.
We ran into this problem with VideoSoft vsFlex3, VideoSoft vsOcx6, Videosoft vsFlexGrid7, Sheridan ActiveThreed (threed20.ocx) and Sheridan Data Widgets 3.0. (VideoSoft has been taken over by ComponentOne, but they couldn't or wouldn't support the old versions). We overcame this problem by creating our own install routine for the 32-bit ActiveX controls. The steps to solve the problem are as follows:
If you would like to talk to us about preparing a custom install routine for your third-party ActiveX components, please ask for Dave at 1-800-326-6686 or email us at dmkaufmann@DTSdenvertax.com (Remove the "DTS" from the email address. That was added to confuse spammers!)
To provide a custom install routine we would need your license number or CD key.
