The problem with COORD Structure in Visual Basic 6.0

[defanive]

I found that most of the console api functions can not be used in Visual Basic 6.0, and I try to find out the problem. Then I found all of the api functions with COORD structure can not be used in VB6, including GDI api functions with COORD. Maybe the Declaretion in API Viewer 2004 get wrong?

Public Type COORD
X As Integer
Y As Integer
End Type

and the Declaretion in VC

typedef struct _COORD {
SHORT X;
SHORT Y;
}COORD, *PCOORD;

Are there any problem? The Structure and API functions are useful for us.

COORD is the same as POINTAPI but uses Integer instead of Long.

I've used COORD several times without problems... what problem are you having?

Welcome to the forums.

Structure looks fine to me, consider it may be your code.
Here is an example of that structure

I don't think there are any problems with my code. The code can be run in VC++ 6.0, but can't in VB6.

These Declaretions are from API Viewer 2004, they're used in my code:

Public Declare Function SetConsoleScreenBufferSize Lib "kernel32.dll" (ByVal hConsoleOutput As Long, ByRef dwSize As COORD) As Long

Public Declare Function GetStdHandle Lib "kernel32.dll" (ByVal nStdHandle As Long) As Long

Public Type COORD
    x As Integer
    y As Integer
End Type

and the main code

hOut = GetStdHandle(-11)
Dim crd As COORD
crd.x = 100
crd.y = 100
MsgBox SetConsoleScreenBufferSize(hOut, crd)

it always returns 0, i have no idea.

(BTW, thx for your replies)

Oh, i think i got the answer.
i think i should get the Handle of Screen Buffer instead of Handle of Output, is that right?

[defanive]

But ... How can i get the Handle of Screen Buffer ?

[defanive]

I read my C++ code again, the first argument should be Handle of Output. Did my code in #4 get wrong ?
