Hello from Gregg C Levine
Stan, about that comment, "actually--- no. ActiveX capability didn't
come along until VEE 6.".

Actually you're wrong. According to an eval copy of VEE 5.0 it can do
Active X controls. And I've run it. It's not as well defined as say
6.0 or the current family of 7.x but it could do it. It might not
return the advanced features that the individual wants however. The
individual should test this for himself. (Or herself.)

I used it in a application where I was using Matlab, and I like this results better. And it is very lightweight too. Attached a sneak preview (jpg) and example program of what can be done with this activex. But there are two things that kept me from using it all the time: first, the program can crash if used on outdated VEE; and second I couldn't manage to get the mouse info when clicking on the chart. For those who like long explanations, read below, some of the mails I sent to and received from our VEE guru Shawn. For those that like to try the example right away, it contains no bugs, but before changing anything, read below.... . To use the activex you will need to download gdi+ too, link provided in download section of the site I also dropped the author a note in the user forum, maybe he can help us out. Thanks to Shawn for his efforts. Nelson ------------------Part of original mail to Shawn-------------------------------------------------------------- The activex can crash when called in runtime (vxe) after working fine in development. I solved that problem by updating the runtime with the latest patches (or downloading latest runtime form Agilent). Also, some errors in development don't give simple activex error messages, but a BRB with a error number above 900. Saving with another name and correcting the error (when you figure out which error it is) allows you to continue working, but I think that many on the VRF will get heart attacks if I dont warn them on that, when I post this example. What I really want to know if you can help me with is the "mouse info" issue. It works in VB6 (like in the MiniDesigner example that comes with the activex), but not in VEE. Can you give me a hint or workaround to get the mouse info from this activex? Or do I have to use on of the examples you posted in the past to get the mouse position, button etc? If I get this clicking working I would post the example right away, otherwise it would be a "example with buggy activex and crash warnings" that the VRF may not appreciate. (just for the record: example that I am sending aint crashing on my pc). --------------------------------Part of replies from Shawn---------------------------- <PRE wrap="">> The activex can crash when called in runtime (vxe)> after working fine in development.That could be a problem. One thing - they're using GDI+ to draw, and I'venoticed that I have problems with that too. You might want to ship thelatest GDI+ setup along with your app and run it from a batch file beforeyou install the control, then do the runtime setup... what a pain VEE8.0 may make this a lot easier as Agilent was talking seriously aboutincluding a packager.Also, unfortunately it is an external library. The documentation doesexplicitly mention VB, but it doesn't explicitly mention any scriptlanguage. Though it includes ActiveX, it's probably VB's own version of"automatic" ActiveX which can cause problems with script languages. Itcertainly looks as if it's VB, but it can be hard to tell. The OLE Viewgenerated idl file is attached. You can use Notepad to view this file.I don't see any problems, but these things can be quite funky. Remember thatquite a few controls didn't work in VEE when it first added ActiveXcapability.</PRE> <BLOCKQUOTE type="cite"><PRE wrap="">> but I think that many on the VRF will get heart attacks> if I dont warn them on that, when I post this example. </PRE></BLOCKQUOTE><PRE wrap="">Hehehe!

At least then you'd be sure that when youenter your click processing the click came from somewhere in the graph. Ofcourse, that would involve yet another library, the Subclass library. And itwould have to be customized to subclass the control's window though that'snot much of a problem.</PRE> <BLOCKQUOTE type="cite"><PRE wrap="">> Hope you can point me in the good direction, </PRE></BLOCKQUOTE><PRE wrap="">Well if you're not spinning in circles by now you got some cajones. I thinkthe best course of action is to go ahead and post. Maybe someone has usedthis chart before and has already found a solution. And besides, peopleshould know about this chart. It *is* very nice.Further - I believe you are on the correct path, it's just going to takesome spiffy troubleshooting to find the problem and fix it once and for all(if possible). After all, it may be that the root cause of the problem is VBand not VEE at all. It looks like the author did the sensible thing: the APIis in the DLL, and the OCX is just a wrapper.If the wrapper is causing problems, you can wrap the control using COMinterop. It will probably be more difficult to control, but it will alsoprobably be more stable. Hopefully!Finally, the author may be able to help. It's a new control, and there areundoubtedly mistakes here and there. It may be that a parameter is typed asInteger when he really meant Long (VB ints are 16-bits. This one has bittenme several times). I don't see any, but I didn't look *real* close. Andanyway, this interface might not be VB at all. The whole thing might havebeen written in C++. If that's the case though, the man is extraordinarilydisciplined!-------------------------------------------------------In the attached, double click on the graph to get the coords. Now, you'llnotice that the numbers don't match up. The numbers the code gets aregreater than the numbers the graph says. That'll be a coord system mismatch,though exactly what coord system the control is using is in question. Ifit's VB, I think the default is Twips though that doesn't seem to square. ATwip is .144 pixels. Wait... that *does* kinda square...It's possible the graph is doing it's own scaling instead of using Windowsscaling, which is a Windows no-no though lots of people do it. One is*supposed* to modify the attributes of the DC so that ScreenToClient worksproperly.At any rate, all I have to do is figure this out and then you'll at leasthave double clicks. That's better than nothing. In the mean time, go aheadand let the author know what's going on - the parameterized events aren'tfiring to VEE through ActiveX. I have a sneaking suspicion that it's becauseof RMC_INFO. For this structure to be IDispatch compatible, it has to be anobject in it's own right, not just a VB Type (or whatever they're calling it---------------------------------------------------------------------Yeah that's the story. It's doing it's own coordinate system. Thetransformation solution can be in one of two ways:If you want a universal solution that will work on any computer at anyresolution, the GDI function DPtoLP is the way to go. The mapping mode isMM_ANISOTROPIC, which is why ClientToScreen doesn't work. It wouldn't workif it was MM_ISOTROPIC either. These two modes are for user definedcoordinate systems, and ClientToScreen is powerless to deal with them.If you're not really worried about changing resolutions or devices (i.e.it'll always be like 1024x768 at 96dpi or something), then you can come upwith a transform formula yourself quite easily. The relationship is linear,and you know the x and y sizes. Basically all you have to do is figure outwhere 0 is for the x and y offsets and come up with a scaling factor thatworks.If I'm mousing right, the point 0,0 seems to be about 254, 478. Subtract 254from x, 478 from y and then multiply by some scaling factor that seems to bevery close to about -0.35 in the y and 0.25 in the x and you have yourcoordinates.In the attached version of the program, I have added this transformationinto the DblClick event. If you run this at 1024x768 at 96dpi the numbersshould match pretty darn closely between the graph and the double click.in PB if that was the source lang).</PRE> --- You are currently subscribed to vrf as: vpetrone@kathrein.com To subscribe send a blank email to "join-vrf@it.lists.it.agilent.com".

Well done! Even though my incorrect guesses are included

To all: this really is a very nice chart. It's fast, small and flexible. I
have since confirmed that RMC_INFO is the problem, but that can be easily
cured by the author without a major hassle. Give this puppy a try. If you
like it, ask the author to modify RMC_INFO so it's IDispatch compatible &
offer to donate a few bucks. A little good will goes a long way!
