What data type is the address variable?
What does the NumberOfBytesRead show after the call?
The difficult we do right away...
...the impossible takes slightly longer.

Thank you for the help, this code is working when rewritten from scratch, so the problem is somewhere else in the original project.

address,
Should that not be the contents of p, i.e. whatever variable p is pointing to?

I don't know yet, it is very old and messy code. Maybe I need to rewrite it from scratch and forget about this junk...

Does anyone know if there are any issues installing/running VB5 on Windows 10? Every time I try and Google this I only find articles relating to VB6.
I have an old legacy program in VB5 I need to maintain (until I finally get round to rewriting it in .NET... or, should I say, the client finally decides to pay me to...)

VB6 on Win10 is not even a supported scenario. Your software may or may not work, but there's no guarantee for tomorrow.
Use a Virtual Machine if you need to "update" something. Since you have a VB5 license, I'd expect that you'd also have an OS that supported the IDE at the time.

Well at the moment I've got the VB5 IDE running fine on Windows 7 on my laptop... am considering the Windows 10 upgrade on that, but don't want to lose VB5 in the process.
|
|
|
|
|
This is a highly unusual scenario. I'd suggest setting W10 on a VM and then installing VB5 on top there. That way, you can test to see whether or not the configuration will work together.
|
|
|
|
|
Yes, good idea - but I can't figure out how to get hold of the required product key if doing a clean install onto a VM...
|
|
|
|

Sorry if this si impertinent, to ask a follow-up question like this, but I wonder if you mght know this:
The difficulty with installing W10 in a VM is that it won't recognise it as a free upgrade from my W7, so will ask for a product key - which I don't have (or would need to buy.) But it occurs to me that I could instead go for the W10 upgrade and then, if necessary, re-install W7 in a VM on the same machine... the querstion then is: would it let me? Or would it tell me that the W7 product key has akready been used? As it'd be the same physical machine perhaps it would... but being a VM, maybe it won't... i.e. can one re-use a Windows product key on a VM on the same box as the orginal OS was installed?
|

|
|
|
I don't see why not? The VM runs isolated so it should be okay doing this.

Although legacy codes do run on Windows for sake of backward compatibility. But why would you even want to use such an old language on a new platform?
You may want to upgrade your current application to Windows Runtime. Windows Runtime and .NET framework are separate, Windows Runtime is the native framework provided with Windows 10, where as .NET framework is a separate product that you install.
Read this API[^] for Visual Basic on Windows Runtime.

As I said, it's an old application I wrote for a client way back in the early 90's which I still need to maintain occassionally. It was originally written in VB3, but apart form a minor update to VB5 in the mid 90's has remined pretty much teh same, and is still in use to day - a fact I am ever so slightly proud of  Of course it should be rewritten for a modern OS, but it's no small task, and the client likes it as is, so there is a certain amount of "if it ain't broke, don't fix it" going on. It will have to eb done day, but in the meantime....
|
|
|
|
|
Then the client should not switch operating system. If the OS updates and he breaks the application, then it IS broken.

I think the coder is the one who wants to switch in this case, and the IDE's compatibility is the primary concern. That client doesn't particularly sound like the sort of person who's likely to have ever ventured beyond windows XP. 
|

The coder is heading for problems; an unsupported IDE on an OS that was created years later. It is not just that it will be a 32-bit environment in a 64-bit OS, there will be more recent versions of COM-controls, something VB leans on. Those would be different on XP, generating a error if not compiled on XP.
"Unsupported" really means it could stop working tomorrow. It is never a good strategy to build on something that can be gone tomorrow.

Yes, you're right, and I realise this - but it's a large job to re-write the code, and I don't feel like doing it for free. So until the client is prepared to fork out for it, we'll just have to struggle on with the current code. As the earlier poster pointed out, this client is a tech dinosaur... I have pointed out to them the dangers of the path they are currently on.

The client will be going this path until something bad happens. You need to prevent that, as YOU are the one that knows more about the risk of continuing this path than he has.
At least make sure you are not liable if the thing collapses; because that WILL happen at one point in time.

I know you want info on VB5 specifically, but have you just tried installing it? (Or perhaps copy an installed directory from another older PC)
I had VB6 installed on Win8.1 and after the upgrade to 10 it still works like a charm, had no problems.

Well, that's the obvious thing - but I don't want to risk upgrading and then finding VB5 won't run. Mind you, I believe the W10 upgrade offers a rollback to W7 if wanted, so I guess I could just go that route...
|
|
|
|
|
Personally, I didn't trust that roll-back feature and would strongly suggest you make a disk image ( Clonezilla[^] ) before upgrading if you want to be certain that the rollback is 100% effective.

I have seen other people's solution to the rather small, obscured 'power off' button in Windows 10 - by making a link to shutdown.exe. Unfortunately, as far as I can see, shutdown.exe will not check to see if there are any unsaved documents and will close the computer whether data is saved or not. Also, although you can delay shutdown.exe - this, I think, is made almost completely pointless by the fact that there is no way to cancel it (that I can see).
My idea is to write a small program which will call shutdown.exe after a delay but which can be cancelled. This bit, I'm pretty sure I can do. The part I have no idea how to do is to check to see if there are any unsaved documents so I can give the user the option to quit shut down.
Is it possible to check to see if there are unsaved documents? How would I do this?
Thanks.
