Superscript in RichEdit control?

Hi,

I am using a Rich Edit control in a dialog box and I need set the TM text as Superscript.

Even though I am using the following command, it doesn't give me the solution.

richAttributes.cbSize = sizeof(richAttributes);
richAttributes.dwMask = CFM_SUPERSCRIPT ;
richAttributes.dwEffects = CFE_SUPERSCRIPT ;

SendMessage(hrichEditWnd,
EM_SETCHARFORMAT ,
(WPARAM) SCF_SELECTION ,
(LPARAM) (CHARFORMAT FAR *) &richAttributes);

Any ideas please.

Thanks

I have done the selection using EM_SETSEL before using EM_SETCHARFORMAT.

RichEdit 1.0 doesn't support superscript. Are you creating a 1.0 control, or a 2.0 (or newer) control?

Hi Mike,

I am using Richedit 2.0 only.

What's in yOffset?

Are you trying to set the format at the whole text , or just in the text after the insertion point ?

Btw if the same code works for u with CFM_LINK tell me to ask a question -)

It is 20.

>Are you trying to set the format at the whole text , or just in the text after the insertion point

I am selecting 2 characters using EM_SETSEL

Note:

I tried Bold for testing purposes. Even that doesn't work.
Any clues.

I solved it using CHARFORMAT instead of CHARFORMAT2. But can some one let me know why it failed with CHARFORMAT2.

Maybe you are passing wrong size , OR you dont use RichEdit 2.0 .

For me , the CHARFORMAT2 works . How do you initialize the 2.0 control ?

>you dont use RichEdit 2.0
LoadLibrary("riched32.dll"); Am I using RichEdit 2.0?

>How do you initialize the 2.0 control ?
How do I do it?
After loading the library, then the RichEdit works for me because I have the control inside a dialog box. I simply activate the Dialog box.

>the CHARFORMAT2 works
I do the following.

CHARFORMAT2 richAttr;
richAttr.cbSize = sizeof(CHARFORMAT2);
richAttr.dwMask = CFM_OFFSET | CFM_SUPERSCRIPT;
ichAttributes.dwEffects = CFE_SUPERSCRIPT ;
richAttr.yOffset = OFFSETVALUE;

But if I change to CHARFORMAT, then it works.

Any solutions please.

By the way, are you doing this instead of drawing the text manually, like I suggested you do in that other question?

..B ekiM

No
LoadLibrary("RICHED20.DLL") loads the RIchEdit 2.0 , not RICHED32.DLL .

mikeblas

wfw> No. LoadLibrary("RICHED20.DLL") loads

Right. But how do we know other code in this app isn't loading RICHED20.DLL? The class name used in the dialog template (or in CreateWindow()) answers the question beyond a shadow of a doubt.

Correct , RICHEDIT_CLASS is the RichEdit 2.0 class name .

I use SDK programming without using any MFC code.

I have rich edit control on the Dialog box. The rich edit contorl is not generated at run time.

Shiva

In that case , you may use the RichEdit20A or RichEdit20W ( unicode version ) class .

BTW I never used MFC or any other environement as well - prefer straight API .

mikeblas

> I have rich edit control on the Dialog box.

Uhuh. And what class name have you placed on the dialog resource?

..B ekiM

ASKER

I am directory placing the rich edit control from the tools window.

The dialog box is a part of the property sheet.

Did I answer?

Ok, now I understood.

The RC file has the following.

CONTROL "Test",IDC_RICH_MSG,"RICHEDIT",ES_MULTILINE |
ES_READONLY | ES_WANTRETURN | WS_DISABLED | ES_BORDER, 15, 42,209,87,WS_EX_DLGMODALFRAME | WS_EX_CLIENTEDGE | WS_EX_STATICEDGE

Regards and Thanks for your interest.

Then you're using RichEdit 1.0, and that's why using the 2.0 version of the structure failed.

Am I supposed to use RICHEDIT20A in place of RichEdit?

Yes .

No. You should use RICHEDIT_CLASS in place of "RichEdit".

..B ekiM

I am not sure if RICHEDIT_CLASS will work on a resource script .

mikeblas

Resource scripts expand macros all over the place. No problem.

The Resource Editor in VC++ 6.0 still doesn't know about the class, no matter how you spell it. So, the control will appear as a "Custom control" in the editor.

You'll need to make sure the resource header has the Richedit headers, so you'll want to use the "Resource Includes" command in the "View" menu to add an #include "richedit.h" directive _after_ the directive to include afxres.h.

But, the resource compiler has always been able to expand preprocessor symbols.
