Done - for MFC and for ActiveX
e.g. in VB sample use
 
With SyntaxEdit1
  .SyntaxSet "[Schemes]" & vbCrLf & "VBS" & vbCrLf & "[Themes]" & vbCrLf & "Default" & vbCrLf & "Alternative" & vbCrLf
  .SyntaxScheme = sScheme2
  .DataManager.FileExt = ".vbs"
  .EnableEditAccelerators = True
  .Text = sText
  .ActivateOnFocus = True
End With

We can add special flag CXTPSyntaxEditCtrl::m_bActivateOnFocus - so no need to subclassing - just set TRUE (let's default be FALSE as now - no activation) and expose the flag to ActiveX]]> Sat, 29 Aug 2009 12:09:52 +0000 http://forum.codejock.com/forum_posts.asp?TID=15058&PID=52556&title=cxtpsyntaxeditctrl-selection-highlight#52556 <![CDATA[CXTPSyntaxEditCtrl selection highlight : I have done now... by subclassing...]]> http://forum.codejock.com/forum_posts.asp?TID=15058&PID=52555&title=cxtpsyntaxeditctrl-selection-highlight#52555 Author: robin_l

I have done now... by subclassing CXTPSyntaxEditCtrl so that WM_SETFOCUS calls SetActive(TRUE) and WM_KILLFOCUS calls SetActive(FALSE). I think it would be useful for other people if this was the default behaviour though.]]> Sat, 29 Aug 2009 12:04:24 +0000 http://forum.codejock.com/forum_posts.asp?TID=15058&PID=52555&title=cxtpsyntaxeditctrl-selection-highlight#52555 <![CDATA[CXTPSyntaxEditCtrl selection highlight : Essentially this is proper behaviour...]]> http://forum.codejock.com/forum_posts.asp?TID=15058&PID=52554&title=cxtpsyntaxeditctrl-selection-highlight#52554 Author: mdoubson

Essentially this is proper behaviour - app should care about such things - control should not dictate it. ]]> Sat, 29 Aug 2009 11:53:45 +0000 http://forum.codejock.com/forum_posts.asp?TID=15058&PID=52554&title=cxtpsyntaxeditctrl-selection-highlight#52554 <![CDATA[CXTPSyntaxEditCtrl selection highlight : It doesn&#039;t do so here.

It doesn't do so here. For example, run your "SyntaxEdit On Dialog" sample. This never shows anything but the non-active selection color (on my system at least):
 
 
If the syntax editor is used in a View, then everything is OK. For example, using the SyntaxEdit.MDITextEditor sample from the toolkit:
 
 
This shows the "correct" selection color (and the dull blue color when the application loses focus). It looks as if when the control is used in a dialog then it never receives the WM_ACTIVATE messages, so CXTPSyntaxEditCtrl::OnActivate is never called (though OnMouseActivate is).
 
The View version calls SetActive via a different route, via CXTPSyntaxEditView::OnActivateView, which does get called.

I am not sure that you are right - if you put breakpoint inside the CXTPSyntaxEditPaintManager code

if (!pEditCtrl->IsActive()) {...
you will see that it will break. Also flag pEditCtrl->m_bFocused exist and accessable from CXTPSyntaxEditPaintManager.

OK... now I'm beginning to understand! I assumed that as the highlighting was not indicating the focused (active) condition that the code didn't do this. Wrong... it does. What the problem is, however, is that the active state is never being set for a CXTPSyntaxEditCtrl so the selection state is ALWAYS the inactive highlight color. This isn't just a problem of my application--you were good enough to create a small sample app that used the CXTPSyntaxEditCtrl in a dialog--this also shows the same behaviour.
 
The active state is set via the OnActivate function call, but this seems never to happen. I can't detect any WM_ACTIVATE messages going to the control--I'm not even sure that dialog controls receive these. This means that the controls are never in the "active" state.
 
What DOES work, however, is to add message handlers for WM_SETFOCUS and WM_KILLFOCUS, and from these call SetActive(TRUE) and SetActive(FALSE). Perhaps you should add these for the CXTPSyntaxEditCtrl so that the syntax highlighting will work as designed?

Right - this is not difficult.
See next post - we already have active and not active color combination.
Used in CXTPSyntaxEditPaintManager::DrawLineTextEx
with defaults:

m_clrValues.crHiliteText.SetStandardValue(::GetSysColor(COLOR_HIGHLIGHTTEXT));

m_clrValues.crHiliteBack.SetStandardValue(::GetSysColor(COLOR_HIGHLIGHT));

m_clrValues.crInactiveHiliteText.SetStandardValue(::GetSysColor(COLOR_INACTIVECAPTIONTEXT));

m_clrValues.crInactiveHiliteBack.SetStandardValue(::GetSysColor(COLOR_INACTIVECAPTION));

And function to switch:

if (!pEditCtrl->IsActive()) {

if (crHiliteBack == m_clrValues.crHiliteBack.GetStandardColor())

crHiliteBack = m_clrValues.crInactiveHiliteBack;

if (crHiliteText == m_clrValues.crHiliteText.GetStandardColor())

crHiliteText = m_clrValues.crInactiveHiliteText; }

So find why it does not covered your expectation - please debug your mutli-controls case with attention to this switch
