Classic VB6 conversion

VB6 and VB.NET are very similar in many ways.

I am having a difficulty trying to see whats going on, partly because of the method being literally over 5,000 lines of code but also partly because things are being done here there and everywhere.

I am trying to convert it ultimately to C# but VB.NET is fine.

Code:

---

Dim validScenario as tScenario

if condition then
  with validScenario
      .MsgType = "blah"
  end with

else if condition2
  with validScenario
      .SomeProp = 1
  end with
else
...
end if

---

so what is going on there? Everytime there is a with, is it using a new instance of the type or is it just using the existing instance and modifying the relevant properties?

I know what with is used for, makes you write less code and faster in performance when using it on the long type. But im puzzled by the above VB6 code.

should I be created a new instance everytime or not?

Possibly this may have made more sense (to write less code):

Code:

---

With validScenario
if condition then
      .MsgType = "blah"
else if condition2
      .SomeProp = 1
else
...
end if
End with

---

Of course that thought is just based on the info provided, and as you alluded to, it's more complex than that :)

... and each time (both code versions) the same instance is being used, and that shouldn't be altered.

If that is the entire block of code, then I have to assume tScenario is a valuetype, because you don't ever actually call a New constructor to create an instance of it.

Regarding the With keyword, no new instance is created, it is from a compiler perspective the same thing as:

Code:

---

Dim validScenario as tScenario
if condition then
      validScenario.MsgType = "blah"
else if condition2
      validScenario.SomeProp = 1
else
...
end if

thanks all. much appreciated - i thought as much that it would be using the same instance.
