 DELPHI DEVELOPER SUPPORT
Areas of concentration under: activex
Area: activex\framework\activex controls\activeform Problem: Apartment threading model activeForm generated by ActiveForm Wizard gives AV in the following situation: 1.IE5's [Internet Option | Advanced | Browsing | Launch browser windows in a separate process] is not checked. 2.Launch two IEs which shows the same html displaying the apartment threading model activeform. 3. Close the first IE 4. Refresh the second IE Active forms of other threading models don't crash at all. We are not sure whose problem this is, IE or Delphi. [JBTS-DP40J3:#205] Area: activex\framework\automation\com servers Problem: Exception message propagation over multiple COM instances fails... Instead of the correct error message reaching the client, the error message gets changed to 'Catastrophic Failure'... Area: activex\ide\import activex control Problem: When you import an activeX control, if an _TLB already exists by that name, you will be asked to verify the overwriting of that file. It may appear that the file was not overwritten (the behavior of what should have been the overwritten control remains in effect). In fact, the overwrite does occur, but the IDE will not recognize the new control until you close and then reopen the newly created _TLB.pas file (without saving it, since you've already performed the overwrite). Area: activex\ide\import activex control Problem: Certain controls which are not registered prior to being imported (and which are thus registered via the 'Add' button) do not behave properly once imported. Area: activex\third party\activex control containers Problem: Importing Microsoft's msdxm.ocx (aka: Windows Mediaplayer) can kill Delphi and crash the operating system. Area: activex\third party\activex control containers Problem: AV occurs when using the FPEditorControl from the TLB for Microsoft's FrontPage editor version 2.0. Error occurs when closing the form that the ActiveX Control is on. Workaround: Explicitly call free on the FPEditorControl in the form's OnClose event. Area: activex\type library\editor\general ui Problem: Keyboard shortcuts for cut/copy/paste don't work when the treeview node is in edit mode -- ie on the text itself. The speedmenu items do. Both work for clipboard ops on the nodes themselves. Area: activex\type library\editor\parameters page Problem: Adding 120 parameters to a method in the type library editor causes Delphi to vanish. Area: activex\type library\editor\refresh Problem: When you change the name of a method, and add the a method with the same name as the old name of the changed one, the refresh only picks up the name change, not the add. Workaround: Refresh twice. Area: activex\type library\editor\text page Problem: Data loss when working with Text pane of a CoClass. The CoClass can lose the information about the Interfaces it implements. Area: activex\type library\import Problem: importing slbcsplib.dll, a win2k system file, results in code that doesn't compile because it attempts to declare a type BYTE which is an alias to type byte. Workaround: Comment out the line with the redeclaration. Area: activex\type library\import Problem: Importing the attached proctexe.exe (a win2k beta system file) results in code that doesn't compile because we generate a setter for a read-only property.NOTE: These listings are for informational use only.
