bulletWhat is the difference between the DLL version of the [Charting, Real-Time, 3D++] product and the ActiveX version?

There are many differences inherant in an ActiveX vs. a DLL library. Both versions of our products provide very flexible, feature rich graphing capabilites, but the programming interface used in each is different. It is strongly recommended that you download the demo for one of our ActiveX controls and the demo for the corresponding Tool library and investigate the similarities and differences.

bullet When I try to use one of the control's property pages, I get a flash and the page I clicked on won't display.

This cause of this problem is that the registration of the grid control (MS Flex Grid) contained in the property page failed, most likely during the installation of the product. To register the grid, in a DOS shell, go to the lib subdirectory where the control is installed, i.e. C:\QCCNTRL\LIB and type REGSVR32 MSFLXGRD.OCX

This should register the Microsoft FlexGrid control on your system.

bullet I have created an application using one of your ActiveX controls and when I try to run it on another computer, other than the one I developed it on, I get a failure.

Some or all of the required files are not present or can't be found on the other machine. Carefully read the section "Redistribution" in Chapter 1 of the Quinn-Curtis ActiveX manual. This section outlines the files that are required.

bullet My copy of your ActiveX controls will not register. What should I do?

If the ActiveX controls do not register from the installation program, do not panic! You may have old MFC and OLE DLLs in your Windows system directory, or an old copy of REGSVR32.EXE.

First try to manually register the ActiveX control. In a DOS shell, go to the lib subdirectory where the control is installed, i.e. C:\QCCNTRL\LIB and type REGSVR32 OCXNAME.OCX, where OCXNAME refers to the Quinn-Curtis ActiveX control that you have purchased.

If that doesn't work, the DLLs can be updated by copying the files MFC42.DLL, MSVCRT.DLL, OLE32.DLL and OLEAUT32.DLL to you Windows System directory. You want to copy over these files only if the ones installed with this software are more current than the files already present. Usually if you have installed a current version of Visual C++, Visual Basic, or Delphi these files have already been updated by one of those installation programs.

Now try and register the Quinn-Curtis controls using the ActiveX register facility of the compiler. In Visual C++ this is the ActiveX Control Text Container, in Delphi it is found under Component | Install | OCX and in Visual Basic it is found in Project | Components | Browse | Add.
