please excuse me for this lenghty post i am an orthodontic surgeon and i am working on a small project in VB6 to help me make some studies on scanned x-ray films of human head taken in side pose, where i will be making measurements between some standard anatomic points, some times drawing lines connecting predefined points and most of the times finding the angles between such lines connecting 3 points. i intend to put a dot on the image when i click the mouse. the dot should be movable on the screen, since i might have to repoition the dot to make it accurate. then there will be options to connect these lines as particular study reqires. i have succeded only to some extent with out using any 3rd party tools. GRAPHICSMILL looks very clever and resourceful. i decided to learn using this by exploring the help documentation to understand the options i need and that this particular tool is giving (since the hospital where i work and live is remote village and feasibility of procuring a VB expert is just next to impossible) the problem is that i donot know how to start using the objects that this particular tool gives. for example i tried to test how the bezier curve is generated by the code that the help documentation shows : ================================= [Visual Basic 6]
Code:
BitmapViewer1.AutoUpdate = False
    
With BitmapViewer1.Bitmap
    .CreateNew 185, 145, Format24bppRgb
    
    .Graphics.Engine = DrawingEngineGdiplus

    'Draw line
    .Graphics.Pen.ForeColor = ColorRed
    .Graphics.Pen.Weight = 5
    .Graphics.DrawLine 10, 10, 100, 60

    'Draw polyline
    .Graphics.Pen.ForeColor = _
        .Color.ModifyAlpha(ColorGreen, 150)
    .Graphics.Pen.Style = PenStyleDash
    .Graphics.Pen.Weight = 2
    .Graphics.DrawPolyline Array(20, 30, 50, 2, 180, 30, 80, 140)

    'Draw beizer
    .Graphics.Pen.ForeColor = ColorBlue
    .Graphics.Pen.Style = PenStyleSolid
    .Graphics.Pen.Weight = 2
    .Graphics.DrawBezier 5, 5, 20, 150, 165, 80, 175, 10
End With
BitmapViewer1.AutoUpdate = True
======================================== as i understand, i have to select the 2 aurigma components from the project menu, then place a BitmapViewer1 on the form and initiate the execution of the above code with an event. but i get the following error: Method CreateNew failed. Argument 'pixelFormat' has an unappropriate value (given pixelFormat is not a member of pixelFormat enumeration) what i think is that i am unable to instantiate the class "Graphics" in this test project. how do i do it? can any body kindly help me with this thing? i am not that much good at programming. kindly answer my question with all the points needed keeping in focus that i might not be knowing some points that you might think are trivial (silly) (and if possible please drop a small project with source code in which 1. i can add a colored point on the control with the mouseclick, 2. can reposition it as needed 3. a text box which holds the x and y coordinates of the dot. i can use these coordinates to draw lines on the image, 4. ability to draw lines between 2 points by selecting 2 points one after the other if that much help is given to me, then i can work out my self and find distance, find angles) please.... :S

Hello, Please excuse me for a delay. Regarding "Method CreateNew failed" problem. It seems you need also add a reference to Graphics Mill 2.0 type library which contains all these constants as FormatXXX, ColorXXX, etc. The problem is that VB do not know what means Format24bppRgb and replaces it by 0. If you add "Option Explicit", compiler will display a error. Just follow these steps: 1. Open Project -> References menu. 2. Find item "Aurigma Graphics Mill 2.0" and set a checkbox for this item. Regarding the code sample, please submit case with it. I will send you a simple project which demonstrates how to implement the features you listed.
