Memory Moving

I need to put a byte array of ASCII character codes into a standard VB string.

Any ideas?

so . ..

MyString = MyBytes()

would be the assignment I would like to achieve. The above code doesn't work, of course!

Cheers chaps

This any good?

VB Code:

Dim i As Long
Dim MyBytes() As Byte
Dim strString As String
 
For i = 0 To UBound(MyBytes)
    strString = strString & MyBytes(i)
Next i
 
MsgBox strString

The application I am trying to do is buffered screen displays. So for instance I have a console window of 78 x 50. This is displayed in a text box, so really I am trying to assign the byte array (2 dimensional) to the .Text property of the textbox.

I currently do it the way you suggest, but to me it feels clumsy. I have tried CopyMemory (Aka RtlMoveMemory) but this doesn't appear to work.

I really need more ideas . . .

You cannot CopyMemory to the .Text property because it is actually the argument of a function, not a string array.

Chrisjk gave you a good answer. Consider locking update on the control while you're moving stuff in there. Speeds things up a lot.

You can use this function to copy a byte array to a string.
DataSize = Length of string

Code:

---

Public Function GetString(ByRef Data() As Byte, ByVal DataSize As Long) As String
    GetString = Space$(DataSize)
    CopyMemory ByVal GetString, Data(0), DataSize
End Function

---

Hope this helps,

I've got it working on one dimensional bytes arrays - but not on two dimensions.

I really want to use RtlMoveMemory, I just can't figure out how to coerce the damn array in.

[When I said .Text, it was for clarity - I put it in a local string first]

I am now using the 'TextOut' API function. This allows direct mappings of strings to DC's

Perfect.

Cheers for your help
