Is there a variable type which can refer to a control (type may differ) in vb6?

Why is Server not receiving multipart/form-data post data
vb6,multipartform-data,winhttprequest
It turns out that if you don't specify the Charset in the content-Type header it automatically assigns UTF-8 at the end of the header. This results in the posted message not working! Solution manually enter the Charset before the boundary. Now it works fine.....tough error to find when you keep...

RegSetValueEx returns “Access is denied”, even though regedit allows the same user to edit this value
winapi,vb6,registry,windows-security
Since Vista was released in 2005, access to HKEY_LOCAL_MACHINE is restricted by UAC. Your user may well be an administrator, but unless the process is started with elevated rights (which RegEdit is), UAC will prevent write access. In order to write to HKEY_LOCAL_MACHINE you will need to ensure that the...

ADO.NET Entity Framework In A COM Visible VB.NET Class Library

VB6 is likely to be using ADO while VB.NET/C# would be using ADO.NET. They are two different data access technologies and there are going to be differences in their connectionstring formats. If you really need/want to connect to the database from the VB6 COM code you'll need an additional connection...

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...
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...
How to create an array with textboxes in Visual Basic 6.0
Your code isn't compiling because it is vb.net code. It should go without saying (but I'll say it anyway) that vb6 and vb.net are not the same thing. If you want to use an array, you will have to dimension the array with a number that is one less than...
How to give file path to “save as” window using vb6
The problem is that you aren't waiting for the SendKeys text to be processed by the target application. A call to DoEvents is not the same thing as waiting for an external application to do something. It allows your application to flush the rest of its event queue. If you...

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...

What would be the role of a Java designer script project in a VB6 to C# conversion?
c#,vb.net,vb6,computer-science
You are correct in saying that *.designer.cs files are usually created by the IDE. However, generating them yourself makes sense here.

Prevent Compile Errors from Non-Compiled VB6 File

Why do I have to register COM DLLs using regasm?

First of all, note that ISO 8859-1 != Windows Latin-1. (See http://en.wikipedia.org/wiki/Windows-1252) The problem is that Java encodes characters as UTF16, so casting to int will generally result in the Unicode value of the char. To get the Latin-1 encoding of a char, first convert it to a Latin-1 encoded...
VB6 Handle error raising in error handler
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).

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...
