Hi

I am new to GUI programming. I am learning MFC and able to create one
application.

But I have one problem that i am not able to solve yet.



Problem:

I want to display a message that tells the upcoming Birthdays. I don't know how
long birthday list can be, so I can't use Static control. I tried to use
DrawText() Function to draw text. I know DrawText() extends the base of the
rectangle to bound the last line of text. I am able to draw the text message but
have following problems.

1. 
   I don't know how to get the correct height of the text
   message rect.

2. 
   How to change the dimensions of the Dialog box according
   the text message.

3. 
   Sometimes Text is not displayed, only blank area is
   displayed. Don't know why?

I want to do something like this:
Link to
IMAGE





I Created DrawText() Function which paint the text. I called DrawText() in
OnPaint().



void CRUNDlg::DrawText()

{



CPaintDC dc(this);

CRect rect,rcDialog,temprec;

CFont fFont;

CFont *fOldFont;

int h; // i tried to use h to calculate height of text but in vain



// rect: for DrawText

// rcDialog: for Dialog dimensions

// temprec: for height calculation of text drawn

//



GetWindowRect(&rcDialog);

GetClientRect(&rect);





dc.SetTextColor(RGB(0,0,196));

dc.SetBkMode(TRANSPARENT);



temprec=rcDialog;

temprec.bottom=0;

temprec.bottom =rect.top=10;



fFont.CreateFont(20,0,0,0,FW_NORMAL|FW_BLACK,0,1,0,DEFAULT_CHARSET,OUT_CHARACTER_PRECIS,CLIP_CHARACTER_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH|FF_DONTCARE,"Arial");

fOldFont =dc.SelectObject(&fFont);



h=dc.DrawText("Birthday Alert",rect,DT_NOCLIP|DT_CENTER);

temprec.bottom+=rect.top;



fFont.Detach();

fFont.CreateFont(15,0,0,0,FW_NORMAL|FW_BLACK,0,0,0,DEFAULT_CHARSET,OUT_CHARACTER_PRECIS,CLIP_CHARACTER_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH|FF_DONTCARE,"Arial");

fOldFont =dc.SelectObject(&fFont);



rect.top+=h+5;

temprec.bottom+=rect.top;

dc.SetTextColor(RGB(14,14,255));

h=dc.DrawText("Following is a Birthday
List",rect,DT_EXPANDTABS|DT_NOCLIP|DT_CENTER);



temprec.bottom+=rect.top;

rect.top+=h+5;

temprec.bottom+=rect.top;



dc.SetTextColor(RGB(0,0,0));

h=dc.DrawText("vikram sharma\t21-11-88\nThis Is
Test",rect,DT_EXPANDTABS|DT_NOCLIP|DT_CENTER);

temprec.bottom+=rect.top;



GetWindowRect(&rcDialog);

ClientToScreen(&temprec);

if(!(rcDialog.bottom>= temprec.bottom))

rcDialog.bottom= temprec.bottom;





MoveWindow(&rcDialog);

CentreTheDlg();



}
