Issues of Visual Studio 6.0 Application in Windows 7 OS

Hi
lI have a VB6.0 application, which is functioning in windows XP operating system,
And I’m going to use the application in Windows 7 operating system.

In this application I am using the following OCX controls,
Keysta32.ocx
Grid32.ocx
Threed32.ocx
Mschart.ocx
The "Support Statement for Visual Basic 6.0 on Windows Vista, Windows Server 2008 and Windows 7" of Microsoft says that these runtime files will not be supported in the Windows 7 OS
Refer: http://msdn.microsoft.com/en-us/vbrun/ms788708.aspx
Unsupported, But Supported and Compatible Updates or Upgrades are Available
dao350.dll
mdac_typ.exe
mschart.ocx
msdaerr.dll
msdatl2.dll
msexch35.dll
msexcl35.dll
msjet35.dll
msjint35.dll
msjt4jlt.dll
msjter35.dll
msjtor35.dll
msltus35.dll
mspdox35.dll
msrd2x35.dll
msrepl35.dll
mstext35.dll
msxbse35.dll
odbctl32.dll
oledb32x.dll
Unsupported Runtime Files
anibtn32.ocx
graph32.ocx
keysta32.ocx
autmgr32.exe
autprx32.dll
racmgr32.exe
racreg32.dll
grid32.ocxmsoutl32.ocx
spin32.ocx
gauge32.ocx
gswdll32.dll
ciscnfg.exe
olecnv32.dll
rpcltc1.dll
rpcltc5.dll
rpcltccm.dll
rpclts5.dll
rpcltscm.dll
rpcmqcl.dll
rpcmqsvr.dll
rpcss.exe
dbmsshrn.dll
dbmssocn.dll
windbver.exe
msderun.dll
odkob32.dll
rdocurs.dll
vbar332.dll
visdata.exe
vsdbflex.srg
threed32.ocx
MSWLess.ocx
tlbinf32.dll
triedit.dll
But I can able to register these OCX files in Windows 7 OS, can able access the properties, methods and events of these controls, and working fine in a sample VB6.0 application.
I need to know,
What are the risks involved in using these Unsupported OCX controls in my application when moved to Windows 7 OS?
If there are any issues then is there any solution / replacement for these OCX controls.
Let me know the detail of the compatibility issues of these OCX controls in windows 7 OS.
Thanks,

Hi,

To make your app Windows 7 compatible, some rewriting of code and reference to .ddl's and OCX.'s is inevitable.
You will have go through it line by line, I'm afraid.

A better option is to rewrite the app from scratch and using your original code for reference.

Good luck.

I can confirm that VB6 will install/run and compile in Windows 7, but you cannot use threed32.ocx.
On my PC I cannot event register the control without getting the 0x80040201 DLLRegisterServerFailed message, therefore I cannot open any project that uses the threed32.ocx. (That's a lie actually, they will open but all the controls that use the threed32.ocx become Picture boxes - great!)
Basically if you want to develop using VB6, stick with XP.
Please note: This is based on Windows RC Build 7100. It may be different for the final release of Windows 7, but I'm not holding my breath.
