change color or Url in RichEdit control

I have some code as follows, to change the text and
background color of the currently selected text in a
control based on RichEdit 2.0.
------------------------------------------------------
CHARFORMAT2 cf;
unsigned int cfSz = sizeof(cf);
cf.cbSize = cfSz;
SendMessage(m_hWnd,EM_GETCHARFORMAT,(WPARAM)SCF_DEFAULT,
(LPARAM)&cf);

cf.crBackColor = RGB(255,0,0);
cf.crTextColor = RGB(0,0,0);
cf.dwMask |= CFM_BACKCOLOR | CFM_COLOR | CFM_LINK ;
if ( cf.dwEffects && CFE_AUTOBACKCOLOR)
cf.dwEffects -= CFE_AUTOBACKCOLOR;
if ( cf.dwEffects && CFE_AUTOCOLOR)
cf.dwEffects -= CFE_AUTOCOLOR;
cf.dwEffects |= CFM_LINK ;

SendMessage(m_hWnd,EM_SETCHARFORMAT,(WPARAM)SCF_SELECTION,
(LPARAM)&cf);
-------------------------------------------------------

however the selected text defaults to blue and is
underlined becuase of the CFM_LINK flags and overrides the
BackColor and TextColor I've set for the characters.

Is it possible to override Richedit's default displaying
of characters that have the CFM_LINK flags set? I haven't
been able to find any documentation on this but believe it
should be possible??? Any insight is appreciated.

Thanks in advance.

You mean if you doubleclick on a *.dws or *.vsproj file or open it from inside VS?
Actually this takes no more than 10 seconds for small project.
How big is your project? (count of files, classes ect.)

Yes, double click on DSW on File->open

I have around 30 classes but I don't thin that should limit the speed, do you ?

It might be due to the "one-million breakpoints" problem. Bring up your breakpoint dialog and check if there's a heap of them set ( usually duplicates. ) Remove them and see if it helps.

Option 2:
If you don't use the class-view info, ( sounds limiting, but it doesn't have to be ),
you delete your project NCB file, create an empty one and make it write-protected.
It will speed up things, at the cost of not having the class-info available.

Are you using any kind of integrated source code control? If so, it will take forever to load up large projects.

Close everything and manually delete these files from the project's folder: *.NCB, *.PLG, *.OPT. Reopen and see if you notice a difference.

ListCtrl: maintain the slection after repopulating it...

Joan M11-Dec-02 5:11

Hello,

INTRODUCTION:
I'm using a normal CListCtrl in a dialog based app.
When I update/edit a value in the ListCtrl (REPORT MODE) I validate it versus all the other values (they must follow some rules) and if some are not as they should have to be, I modify the variables that are linked to those parameters and then I re-populate ALL the ListCtrl reading those variables...

NOTE:
I know that this is not the best method... but it works and I have no time to improve it... moreover there are only 8 elements in the ListCtrl. Blush | :O

QUESTION:
In order not to fool the user I want to be able to place the selection where it was (over the last edited item). The fact is that I can see the selection mark over the desired element, but when I press the down arrow the selection gets placed over the first element. Confused | :confused:

After the edition I'm using this code now:

<br />
if (iElement == -1) iElement = this->m_ElementModificatAct.m_iItemActual;<br />
this->SetItemState(iElement, LVIS_SELECTED, LVIS_SELECTED | LVIS_FOCUSED);<br />
this->EnsureVisible(iElement, FALSE);<br />
this->SetSelectionMark(iElement);<br />

OK, the selection mark is drawn where it should be, but when I press the down arrow I get the selection not in the next element... I get it over the first element...

Could I do anything?

Thank you in advance.

Funny I just solved this after posting a similar question.

change
this->SetItemState(iElement, LVIS_SELECTED, LVIS_SELECTED | LVIS_FOCUSED);

to

this->SetItemState(iElement, LVIS_SELECTED| LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);

Do you think I can use that trick in order for my list control not to deselect all items one it loses the focus ? When I press a button it deselects all items from the list... I have to select them again...

Embedded CPropertySheet : HOWTO change CPropertyPage programatically ???

Luc Bergeron11-Dec-02 4:47

11-Dec-02 4:47

Hello to all,

I have an embedded CPropertySheet inside a dialog and this sheet contains 4 pages. The user can't access the second page unless he has entered and saved a record inside the first one. So in the SecondPage::OnSetActive() I query some data members and if nothing has been entered I call the parent PropertySheet and ask it to SetActive the first page. UI wise the first page is selected but the controls displayed are still those of the second page. What call(s) do I have to make in order to display what the first page has to offer in terms of controls ????

Thanks in advance for any help !

Override the OnKillActive() for the 1st propertypage and return false in no record has been written. This stops the 2nd page being activated at all.

Need to make a MD5 of a file, non-RSA and non-MFC

I need a non-MFC function that takes a filename, and returns a MD5 of the file. I'd prefer a non-RSA implementation, because of limited space for the copyright stuff. Anyone know of such a function?

Thanks!
