VB6 File not found: 'C:\Users\???\AppData\Local\Temp\VBB685.tmp'

I'm not one to hate on VB6, but today's gonna be an exception. Also I want this message to be on the internet so the next poor swine who gets this message might be lucky enough to see this post.

I recently added some functionality to an OCX in our legacy VB6 system. The OCX compiled without errors, but any program that used it could no longer load it. When I tried to reference it in a new project, I got the error "File not found: 'C:\Users\???\AppData\Local\Temp\VBB685.tmp'".

About a week of tearing my hair out followed. I'd just upgraded to windows 10, I'm still not sure if that's relevant.

The thing is, I added a property. Removing it fixed the bug. Adding ANY property broke it again. Eventually I broke compatibility, made two functions which were Public but could/should have been Private .. um, Private, and added my property again. Now it's all good.

I can only assume there's some sort of really small limit on the number of exposed properties of a VB6 OCX. If this is/was common knowledge, well then what the hell google :p

There is no limit on the number of properties. I would guess, however, that it had something to do with your compatibility setting in the project. I'm not going to try and guess what because it's been about 15 years since I last touched VB6. Yay me!

By adding a property you broke the "contract" between the OCX and it's clients. Forcing the break compatibility is the only way (AFAIK) to get around it without supplying another interface. You will probably also have to rebuild any project that uses the OCX

Minimum margins are dependent on the print device that you are sending the output to. I would guess you need to look at printer properties.

There are forums dedicated to VBA, you should try one. Just Google something like "VBA printer settings", and see what it gets you.

You have the selection-start, and its length.

Select the first character, get the name of its font, and increase its size. Repeat for the next character.

Bonuspoints if you keep increasing the selection if the next character has the same font.

VB 2010 Error: Property access must assign to the property or use its values.

Hi.

I got this error and can't seem to solve it. I've changed the code but it gives a error message that I have coded into the program. I've read most of the articles here about it but just can't figure it out. This is the line of code; msgBox(sendWeightRequest). I have changed it to this;

Private Sub btnGet_Click(sender As System.Object, e As System.EventArgs) Handles btnGet.Click
        'Dim weightRequest As String

        If sendWeightRequest() = "ERROR" Then
            WriteLine("Cannot read weight...")
        Else
            MessageBox.Show(sendWeightRequest)
        End If
    End Sub

When I run the program it doesn't give the Modules error message but another ones. Can someone help please?

Where is the variable or method sendWeightRequest? In the first reference you are using the name as a method, and in the second as a property. So which is it?

Function sendWeightRequest()
        If weightRequested = "ERROR" Then
            Return ("CANNOT READ WEIGHT...")
        Else
            Return weightRequested
            Try
                scale_scannerPort.WriteLine("S334" & vbCr)
            Catch ex As Exception
            End Try
        End If
    End Function

Hope this answers your question. On my laptop I get an error at 'Catch ex ...'which reads: ' Unused local variable: 'ex'.', but on my DT I don't get that error and I'm using the same versions of VB on both machines.

Yes that answers your previous question, but you are still using the wrong syntax in your call to MessageBox.Show. As to the error above, you are attempting to catch an exception but you never use the ex variable. However, it does not really matter since you will never get to that Try/Catch block in the firstplace.

Which kind of Datatype do you get from SendWeightRequest ?
If it isn't a string you first have to convert it into String. Messagebox want to get a String as Message. So please try :

MessageBox.Show(sendWeightRequest.toString)

OK ... what is the real return-value from your Function "SendWeightRequest" ? You could see it in the Debugger-Mode.

But ... perhaps you should better offer/provide the code of the Function "SendWeightRequest" ...

But : from where comes the content of the Variable (?) "weightRequested"

I still think that more Information could be very useful ...

Hi guys.

Thanks for the help. I got the code to run error free but now its becoming more complex, but that is for another forum.

Keep on coding...
