  • 1. Problems with sharing TActionList between forms
    I am using Builder 5 and have an MDI application that has an ActionList defined on the main form. The toolbar and main menu make use of this ActionList. But there are some popup menus on the MDI Child forms that also make use of the ActionList and they work for a little while. Then the popup menu items lose the entry in the Action property so I end up with a blank popup menu. I think it has something to do with saving/loading the project and it is not finding the TActionList. If I open up the project and it is in this state and I use the Object Inspector to drop dorn the list of actions, they are empty. But if I open up the main form and then return to the Object Inspectore for the faulty popup menu they can be selected again. This is looks like a bug in the IDE, is there a work around or a fix for it anywhere? Has anyone had experience with this problem and solved it?
  • 2. Ansistring.vprintf() throws an exception
    I've written a function similar to printf but outputs data to a memo control e.g. OutputTextDatabase("Value=%d",Value); Method 1 : Using Char array //---------------------------------------------- void TSubmitForm::OutputTextDatabase(char *fmt,...) { char TextLine[300]; va_list argptr; va_start(argptr,fmt); vsprintf (TextLine,fmt,argptr); SubmitDataMemo->Lines->Add(TextLine); //---------------------------------------------- Method 1 : Using String //---------------------------------------------- void TSubmitForm::OutputTextDatabase(char *fmt,...) { String TextLine; va_list argptr; va_start(argptr,fmt); TextLine.vprintf (fmt,argptr); <---- EXCEPTION SubmitDataMemo->Lines->Add(TextLine); } //---------------------------------------------- Which both work fine until I do this : OutputTextDatabase(""); Method 1 : still works fine Method 2 : TextLine.vprintf() throws an exception Also : OutputTextDatabase("%s","") throws an exception If I change it into : OutputTextDatabase("%s"," ") or OutputTextDatabase(" ") Then it works just fine. How come AnsiString.printf() crashes when you pass on a NULL string (and vsprintf doesn't) ?

Help!! TCppWebBrowser ,popup window and Cookie

Postby Cheng » Fri, 05 Sep 2003 09:32:08 GMT

I set up a CppWebBrowser in my software. It acts as a IE and woks fine.
But If It needs to popup a new window with cookie after clicking related
button inside the CppWebBrowser. It works differently from using IE. It
seems the new popup windows's session is different from the origal

I appreciate any help!
Thanks in advance!

3.TCppWebBrowser Popup Menu Clipboard Copy Operation

The right-click popup menu contains Copy and Select all, which appear to be
supported in that they are enabled and disabled appropriately when text is
selected.  However, Copy does not change the contents of the Clipboard.  Any
ideas how to get this to work, or how to remove the non-functional items from
the menu?

4.Popup window (actually slide up window like AOL/Trillian)

Does anybody have any code to do the kind of status window where the window 
slides up from the bottom displays for a few seconds and then disappears?

I found it for MFC but not C#.

TIA - Jeff.

5.Popup menus and windows move behind app window in XP

All first-level popup windows, whether they be right-click menus, "What's 
this" context popups, drop-down selection boxes, are disappearing behind the 
application window or dialog box being displayed a second or two after being 
displayed.  This behavior is limited to Windows XP and never happens when out 
product is used with Windows 2000.  Sometimes the windows do not disappear.  
When they do, it is only the portion of the window that overlays our 
application window or a dialog being displaying.  It is as if the application 
window or dialog is being redrawn and the order of which window is topmost is 
changed.  Even though the window is drawn behind the frame it overlays, all 
items are still selectable so the popup itemis still on top, but its image 
has been drawn behind.

Our application presents as a floating toolbar and does have the topmost 
flag set so that it never disappears behind other applications.  (It is used 
in concert with other applications and must be visible at all times.)  It can 
also be docked as an AppBar to the top and bottom of the screen.  Docking 
does not change the aberrant behavior of the popup items.

Is anyone aware of a difference between Windows 2000 and XP that would 
explain the bad behavior under XP?  Again, we have no such problems with 
Windows 2000.  Any suggestions for the cause and especially a work-around 
would be greatly appreciated.
