    Re: How to write a COM wrapper?

    I hate to even comment because I really don't know C++ code, but from the looks of what you have posted there your MyDLLFunction isn't returning a value. If your MyDLLFunction doesn't provide a...

  6. Re: Active Property Updates

    WizBang in my previous post I mentioned that the variable was a property of an instance of an OPC class object. The external process is an OPC server providing real time values from an Industrial...
  7. Re: Active Property Updates

    For the benefit of anyone following the thread, I'm posting an example project with a quick down an dirty wrapper class for an image control. The class provides a PictureChange event that I've used...
  8. Re: Active Property Updates

    Ah yes, I know what a wrapper class is. In fact most of the custom controls in question, the ones that need the value bound are essentially wrapper controls. I had thought of doing that, but since...
  9. Re: Active Property Updates

    DG,

    I hate to sound ignorant, but that's essentially what I'm asking, how exactly would I go about creating a change event for something that has no method of triggering said event.

    Are you...

  11. Re: Get Filename from Initialized Object

    Wof,

    Yes, I had considered that option as well, but in the particular case I'm developing the control for, there is the likelihood of a dozen or more instances of the control on a single form, and...
  12. Re: SetWindowLong and WM_MOUSEMOVE

    Thanks for all the input guys. I actually resolved the situation with

    SetCapture Lib "user32" (ByVal hWnd As Long) As Long
    ReleaseCapture Lib "user32" () As Long


    It works nicely. I've...
  13. Re: SetWindowLong and WM_MOUSEMOVE

    DG,

    Thanks for the reply. Yeah, I knew that controls on my my form were child windows of the parent, and ignoring the mouseclicks is fairly straight forward, but I'm actually looking to ignore...
  14. [RESOLVED] SetWindowLong and WM_MOUSEMOVE

    Question for the gurus. I need to be able to ignore the mousemove event selectively for a selected control on a form. More specifically, I need the X and Y mousepointer coordinates to reflect the...
  15. Re: Get Filename from Initialized Object

    WoF,

    Thanks. That was pretty much the conclusion I had come to. I have another workaround but I just don't like it as much.

    My Situation is this. I have developed a custom control that has...

    I'm afraid I already know the answer to this question, but hey, it never hurts to ask right?

    My Dilemma:

    I need a Control that is Arrayable for muti-instancing, contains a picture with a stretch property, and can be dynamically positioned at runtime with the mouse. In order to satisfy...
  21. [RESOLVED] Out of Stack Space and Reserved Words

    I am subclassing (if what we do in VB can actually be considered true subclassing) I've created a control with nothing but an image on it. I've defined all of the properties I need in my control...
  22. Re: UserControl Events Problem

    Thanks for the warm welcome and the fantastic response. The code worked beautifully. There is a slight delay in the event response but IT WORKS, and the delay is a small trade-off for having the...
