Insert New Button to my IE Toolbar

}
}


Now I have to insert a new button that have caption without an image to the toolbar at the runtim, but every time I try, the toolbar buttons disappeared. However when I add a new button with an image and no text every thing works fine.

void CBandToolBarCtrl::AddInboxButton()
{
char MyButtonText[]="My Button\0\0";

TBBUTTON pTBBtn;

pTBBtn.iBitmap = I_IMAGENONE;
pTBBtn.idCommand = ID_BUTTON_INBOX;
pTBBtn.fsState = TBSTATE_ENABLED ;
pTBBtn.fsStyle = TBSTYLE_BUTTON | TBSTYLE_AUTOSIZE | BTNS_SHOWTEXT;
pTBBtn.dwData = 0;
pTBBtn.iString = SendMessage(m_hWnd,TB_ADDSTRING,NULL,(long)&MyButtonText);;

SendMessage(m_hWnd, TB_INSERTBUTTON, (INBOX_BUTTON, (LPARAM)&pTBBtn);

}

I need help to get this done. I will appreciate any suggestions.

Thanks in advanced
