I would be interested.
Recently I posted about needing help with C# and a dll that I built
in PB

I got everything working except when the parent form (C#) closes,
even though I purposely (or think purposely) tell Windows to release
my dll, I still get an error because it just won't let go.

I too am still learning, but have a good programming background and
can usually learn a lot from examples.

Cliff,

Here is the link to download the ZoomPlus project.
Download the demo
It is written with "Visual C# 2005 Express".

The GDImage.dll itself is written with PB/WIN 8.xx
and it works like a charm with it.

Of course the first thing to do is to create a Class
to encapsulate the Win32 DLL, see below:

class GDImage
{
// ANCHOR properties
public const int ANCHOR_NONE = 0;
public const int ANCHOR_WIDTH = 1;
public const int ANCHOR_RIGHT = 2;
public const int ANCHOR_CENTER_HORZ = 3;
public const int ANCHOR_HEIGHT = 4;
public const int ANCHOR_HEIGHT_WIDTH = 5;
public const int ANCHOR_HEIGHT_RIGHT = 6;
public const int ANCHOR_BOTTOM = 7;
public const int ANCHOR_BOTTOM_WIDTH = 8;
public const int ANCHOR_BOTTOM_RIGHT = 9;
public const int ANCHOR_CENTER_HORZ_BOTTOM = 10;
public const int ANCHOR_CENTER_VERT = 11;
public const int ANCHOR_CENTER_VERT_RIGHT = 12;
public const int ANCHOR_CENTER = 13;

// ZD_DrawText constants
public const int ZD_TextHorzUp = 0x0; // Horizontal text orientation
public const int ZD_TextVertUp = 0x1; // Vertical text orientation from bottom to top
public const int ZD_TextVertDn = 0x2; // Vertical text orientation from top to bottom
public const int ZD_HIDE = 0x0; // FALSE
public const int ZD_SHOW = 0x1; // TRUE

// GDImage overlay Generic STYLE must be a 2^
public const int ZS_HIDDEN = ZD_HIDE;
public const int ZS_VISIBLE = ZD_SHOW; // VISIBLE, same as WS_VISIBLE
public const int ZS_SCROLL = 0x2; // MOVE with scroll bars, default is FIX (do not scroll)
public const int ZS_DRAFT = 0x4; // Draft drawing mode

public const int ZI_FitToWindow = 7; // Resize the image to fit the view port
// And use any of this constant as Parameter
public const int ZI_QualityDefault = -1;
public const int ZI_QualityGood = 1; // Best performance
public const int ZI_QualityHigh = 2; // Best rendering quality

public const int ZI_GradientTop = 5; // Set/Get top gradiant color backgroud
public const int ZI_GradientBottom = 6; // Set/Get bottom gradiant color backgroud
public const int ZI_ZoomWindow = 11; // Set/Get zoom window status
public const int ZI_Orientation = 13; // Set/Get orientation

public const int RotateNoneFlipNone = 0; // GDI+ constant
public const int Rotate90FlipNone = 1; // GDI+ constant
public const int Rotate180FlipNone = 2; // GDI+ constant
