Compare items in an Array to items in a Variant in VB6
This really isn't a Variant problem, it's just a looping/control variable issue. Even though you have your DIM statement inside your main loop, VB does not treat that as a "redeclaration" and reset/reinitialize its value before your UNTIL loop. As a result, 'i' will increment to 1 and then retain...
FileSystemObject calls executing… too fast?
I suspect your problem is that shell returns immediately after starting (or failing to start) the process. I would suggest using the API call CreateProcess and waiting for at least a little bit for the process to return a result. I use this enough I've created a method for this....

Set vb6 form to instance of a hardcoded form
The best solution for this is using what Bob77 said and applying it to the form. When loading Form1 using the Forms.Add("Form1") method if you were to implement Set Form1 = Me in Form_Load it will now set the reference of Me to be Form1 so that when you made...
Is Visual Basic a very useful Programming Language nowadays? [closed]

Prevent Compile Errors from Non-Compiled VB6 File

Yes, keybindings do exist and you're in luck; the keybindings below relate to Visual Studio 2010's Visual Basic.

Why is Server not receiving multipart/form-data post data

Code difference between the two times
You need to use the DateDiff function. You also want to be storing values in variables declared using dim variableName as Date, not text boxes. You'll also want to sanitize the input somehow, so that your program doesn't crash the first time someone enters "bob" as a time.
When VB6 application will end?
The "2024" means as part of Windows 8. The link says the VB6 runtime is part of Windows and therefore will be supported in the same way as the rest of Windows. For example Windows 8 will be supported until 2024 because that's the support lifecycle for Windows 8. Microsoft...
Does the C# await can be compared to former old VB6 DoEvents?
In some ways they can appear similar at first glance. DoEvents will run a nested message loop to allow other methods to run on that thread before the current method finishes. Similarly, await will "yield" control to other methods, allowing other code to run on that thread before the current...

What is happening in this code
Your edit still makes not enough sense - unless the code was SendMessageStr List1.hwnd, &H18D, &H20, "directory*.*" and you thought the space means it's a stand-alone bit (it isn't). That code is SendMessage (List1.hwnd, LB_DIR, DDL_ARCHIVE, "directory*.*") - it sends a documented Windows message to a ListBox control named List1...

How to correctly use On Error Goto for different HRESULT values
COM specifies which values in a HRESULT are treated as errors, and which aren't.

Is using variants in vba bad for performance?
It depends. Variants are slower then native types, but in most programs, it doesn't matter at all. Most macros are small and get compiled when run and the diference may be a few microseconds, that you can't perceive. Variants have their advantages, I love them. So it depends on what...

You'd rather use RESUME than GOTO in the error handler section: On Error GoTo ErrorHandler maxretry=3 c=1/0 Again: c=a/b ErrorHandler: if maxretry>0 then maxretry=maxretry-1 Resume Again end if Using RESUME will, sort of, reset the internal error handler flag and giving you re-entrance in it (sort of).

A long in vb6 is a 32 bit signed value, so its range is - 2,147,483,468 to 2,147,483,468. A long in C# is a 64 bit signed value, so its range is –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. In the vb6 XOR you are overflowing, thus why the number is negative. To get...

Why do I have to register COM DLLs using regasm?
