That's true of course.
But still your solution is not valid if the application is a ANSI build (i.e. UNICODE is not defined) and yes, you may use COM with a ANSI built application, provided you explicitely convert strings.

CString text_filename = TEXT("c:\\text.txt");

works fines on ANSI and UNICODE.

I prefer buildind Unicode, because COM can be easier used. So my code is Unicode compilable.

I also like the CStringW class for COM in ANSI projects Blush | :O

Indeed. But it doesn't automagically convert a ANSI string to a wide char one. That's why I said it wouldn't help him on a ANSI build.

Setting a CToolBar Button's Label to take multiple lines of text

David Ferreira2-Mar-10 22:54

2-Mar-10 22:54

I've been trying to figure out how to get the buttons on a CToolBar to accept the newline character like a normal button does when you set the multiple line property to true.
Apparently the buttons on a toolbar are not normal buttons so i cant get a handle and there is no multiline style like there is on a normal button.

I've got (this is in a class that inherits CToolBar)

CToolBarCtrl& bar = GetToolBarCtrl();//CToolBar::GetToolBarCrtl
int nIndex = 0;
CRect NoTextRc( 0, 0, 0, 0 );
bar.GetItemRect( 0, NoTextRc );
bar.SetMaxTextRows(3);//sets the max number of rows
bar.SetDrawTextFlags( 0xffffffff,  DT_WORDBREAK);//Should Break line on space and /n

Line 1 gets the toolbarctrl for the toolbar in question
Line 5&6 should make me able to have 3 rows of text and break on a space or a carriage return
What it is doing is just not displaying any text after the space or the /n.
I've made the size of the button really large just incase the button wasn't big enough with

SetSizes(CSize( 120, 100 ), CSize( 90, 36 ));//CToolBar::SetSize

Here is where i set the text of the toolbar
The commented code are failed attempts at making the button multiline in the same mannar as a button

if ( !strButtonText.IsEmpty() ) 
{
    //SetButtonStyle(nIndex,ES_MULTILINE);
    strButtonText.Replace(" ","\r");
    //bar.SetStyle(ES_MULTILINE);
    SetButtonText( nIndex, strButtonText );//CToolBar::SetButtonText	
}

All the above is in a class that inherits CToolBar.
Can anyone please help me out here i've spent way more time than i should on this and i have no solution in sight.

You mean in the CString::Replace()?
I was fiddling with it and forgot to change it back.
I've tried /n, /r/n, /n/r, /0
I was grasping at straws there, lol. You are right it's meant to be /n (at least i think it so too).
That may have creating a whole new set of problems for me thank you.

I used the wrong slash in the reply i apologize but i'm assuming you mean in the CString so what i meant in the replay is that i mistakenly used \r instead of \n in the CString.

so in

strButtonText.Replace(" ","\n");
SetButtonText( nIndex, strButtonText);

Where CString strButtonText is the CString destine for the label of the button
I originally had = "Customer Details"
After Replace i have "Customer\nDetails"
So i'm sending "Customer\nDetails" to the label, however i'm just getting "Customer" and the "Details" part of the string is missing instead of appearing on the next line.
If i Omit:

bar.SetMaxTextRows(3);
DWORD dwSIZE = bar.SetDrawTextFlags( 0xffffffff,  DT_WORDBREAK|DT_CENTER|DT_MODIFYSTRING );

I get "CustomerDetails"(no space) in the label after replacing the space with a \n in the string. So the \n from the CString is ignored like it would be in a normal button with its multiline text property were set to false.

Basically it seems as though the text is going to the next line but not visable even thought the buttons size is greater than that of the text.

Sorry if i'm missing your point but i've never used \n anywhere but in a string and strButton is the only string there which as mentioned at the time of going to the label contains a \n should it have originally contained a space. The DT_WORDBREAK also treats a space as a \n when the text is 2 long to fit on one line.(at least that is what i'm led to believe.)

Thank you again for the response i get one step closer to the solution with every one Smile | :)

use a tooltip for detailed information, a toolbar should be short.
or you make a toolbar of your by ordering some buttons as a "user toolbar". Cool | :cool:

No, I don't feel like going to some website and trying something.

You could try it yourself, and ask a specific question here (as long as it's related to C/C++/MFC).

Did you look at the hijr.js file that this sites uses? It looks to be used by qibla.cgi to compute dates and such.
