[RESOLVED] VB6 Locks up at breakpoint in Windows 10

[webbiz]

I've got VB6 installed and running in Windows 10 after following some tips.

Unfortunately, it doesn't behave right.

For example, when I set a BREAKPOINT and then RUN the app, it stops at the breakpoint, highlights it normally, but then I can't do anything else. It just 'dings' whenever I click on something.

I've set compatibility to XP, win7, and Run as Admin with no success.

I also notice the Inspect window opens in another monitor (I have 3 monitor setup).

Any suggestions?

TIA

I've been using VB6 under Windows 10 for several years without any issues. You do need to set the compatibility for XP and Run-as-Admin, but apart from that, it's straightforward.

I followed the instructions at 40 Pound Head to get these results.

Do you have Service Pack 6 for VS6 installed?

You actually don't need this and it's dire consequences have been discussed enough here. Can we stop spreading FUD already. . .

Yeah I have never set compatibility on VB, Just install it properly and set it to run as admin and haven't had any issues.

As far as the issue reported in the OP I would guess that there is a message box popped up somewhere that is blocking the IDE.
Under such condition all you will get is a ding when you click on anything in the ide until you clear the message.

When it gets to that breakpoint, can you minimize it? Or at least, using Windows key-combos, see ALL apps that may be running (visually)? There MAY be a pop-up BEHIND your VB6 screen(s).

I have the misfortune of having to work with VB6 in a professional capacity, not just as a developer among two dozen in the group, but as a buildmaster who sets up Jenkins on Windows Server 2019 servers for automated build jobs.

Yes, you can install VB6 without XP compatibility and without run-as-admin, but it won't work properly. We've been there, done that, got the T-shirt.

is the code doing subclassing anywhere?

as dz32 is point at,
what does your code do. maybe it has nothing to do with windows 10 at all.
a "break" can crash the entire IDE, if done in the "wrong" time.

Unfortunately I cannot minimize it or anything else.
And I pull up the task manager to see what is running and also place my mouse over the taskbar icon to see what is visually up and there are no message boxes.

In addition, I've tried this in VirtualBox with both the Windows 7 OS and the XP SP3 OS. In all cases, it acts the same.

So this leads me to think I have some wacky settings or something. I've installed my VB6 from an ISO in all cases, Disk 1. It doesn't appear to ask me for Disk 2.

Puzzled.

YES! It is monitoring the mouse for scrolling. I didn't think of that. I'll disable that code and give it a try. Thanks!

Well, I disabled the subclassing code making sure to comment out the Hook/Unhook. And sure enough, it is behaving normal now.

Thanks a bunch. I forgot how 'hooking' the app and requires an 'unhooking' before I do anything to disrupt the run or close improperly.

MST has IDE-safe both subclassing and hooking so that debugger does not freeze on breakpoint and IDE does not crash when session is stopped with End button.

I'll have to check that out. Thanks. :-)

I know this is a 'resolved' thread but I thought I should at least mention something on this.

In my case, I do need to use my Win7 or XP virtual machine to do 'some' VB6 IDE work. This is because I am using a third-party library from Infragistics called SSActiveToolBars where the menu customization does not work or show up at all under Windows 10. So when I have to add or modify a menu item, I have to go to the VM with XP, make the change, then move my dev files back to my regular Windows 10 (non VM) to continue work as usual. Odd problem.
