Loading Bitmap into a CString

 i have two bitmaps which are basically "+" and "-"

I have to add them infront of a text to indicate if it can be expanded or contracted.

eg if i have word like Inbox is should appear " + Inbox" where + being the actual bitmap.

Is there any way is can load a bitmap in a CString by any chance.
I know that is i overload the CString class for this purpose i might be able to do it bit i am not sure how to go about doing that.

Any ideas.

If you need to use UNICODE, just compile your app with 'UNICODE' defined in your project options, then CString will support UNICODE and you can use it just like

CString Plus = _T("+");


CString Plus = L"+";
Why would you want to use a bitmap? Just use the corresponding letters, e.g.

CString text;

text = "+ " + text;
text = "- " + text;

You could store the bits of a bitmap to a CString. But if you would print it or draw it you never would get the bitmap printed or drawn but only binary rubbish. Look at the graphical output functions: you have a DrawText, MoveLine, BitBlt, ... for any kind of data there is a separate output function. So, if you need to associate a bitmap to a CString, you should make an association, e. g. by a new class:

class TextItem
     HBITMAP  bitmap;
     CString    text;
     // ....

Or, you folllow the advise of jkr and use the font characters +- instead of the bitmap.

i actually thought abt the idea from jkr, it does seem to be the most simple one.
How would i increase the font of the + and - so as to make it appear much bigger.

You cannot have two different fonts in a seingle string, unfortunately. That would requre two text fields or a separate one for '+' or '-'. Then you can set a different font using 'CreateFontIndirect()' and 'SetFont()'


// define the logical parameters for the font
LogFont.lfHeight = -11; // size 8
LogFont.lfWidth = 0;
LogFont.lfEscapement = 0;
LogFont.lfOrientation = 0;
LogFont.lfWeight = FW_NORMAL;
LogFont.lfItalic = 0;
LogFont.lfUnderline = 0;
LogFont.lfStrikeOut = 0;
LogFont.lfCharSet = 0;
LogFont.lfOutPrecision = OUT_STRING_PRECIS;
LogFont.lfClipPrecision = CLIP_STROKE_PRECIS;
LogFont.lfQuality = DEFAULT_QUALITY;
LogFont.lfPitchAndFamily = FF_SWISS | VARIABLE_PITCH;
_tcscpy(LogFont.lfFaceName, _T("Lucida Sans Unicode"));
// create the associated font

CFont cf;

I have declared to CStrings

CString Plus = _T("+");
CString Minus = _T("-");

i just need to increase the font of each of those strings.

CreateFontIndirect(): i will call this to set the font params but how do i link the Plus and the Minus to that font.

Not at all. You'll create a font that way and assign it to a edit or static control that should resemble that sign, e.g.

CFont cf;
CString Plus = _T("+");

i am using the dundas software ultimate grid and in there i am trying to set the cell text

UGCELL cell.settext()

i got the part where u set the font size in cf but how do i am confused about assigning it to a edit ot static control.

this is what i have

CString Temp = Plus + ElementP->Name;

which gives me "+ Currency"   (eg)
If you want to use different font sizes, you need to use different controls.

in that case, i am now trying to use unicode characters

this is what i am trying

wchar_t Plus = 2500 ( which is the unicode value in hex)
wchar_t Minus = 253C

since i need to add this to a CString, how should i go about doing this.
i.e how do i convert wchar_t into CString.

jhav1594Author Commented:
i cannot change the project options due to other reasons

Is this right

wchar_t * Plus = (wchar_t*)malloc(2);
*Plus = 0x2500;
wchar_t * Minus = (wchar_t*)malloc(2);
*Minus = 0x253C;

Let me know
>>i cannot change the project options due to other reasons

Then just add

#define UNICODE

to the top of your "StdAfx.h", the effect will be the same.


wchar_t Plus = L'+';


wchar_t* Plus = L"+";

might be a little bit more straight foward.

but i dont want to use '+' . i want to use the symbol defined by the UNICODE (hex) 2500 and 253C as mentioned in MSWORD -> Insert -> Symbol

wchar_t * Minus = (wchar_t*)malloc(2);
*Minus = 0x253C;

the *Minus is just taking in '3C' and hence the result '<'
what do i do so that Minus takes in 253C

i am doing the following to convert it into CString

CString Temp.format("%c", *Minus);

Well, then

wchar_t Plus = (wchar_t)0x2500;

wchar_t Minus = (wchar_t)0x253c;

should work.
