I'm trying to display the PI symbol on certain static text variables in a Dialog box. I know I can set all the text in the dialog box to the symbol font but is there a way using SetFont in the OnInitDialog() function to allow me to change the only certain ones to the symbol PI?
Also how would I put a subscript/superscript on a static text? Would this be done using some sort of RichEdit?
Any help would be nice.

1. Remember to delete your font after use.
2. This is only a sample, please custom it yourself

why delete the font after you used the SetFont()? Please refer to : http://www.flounder.com/detach.htm

I have been reading line after line of code and instructions of classes and instances, declarations and structures....I think I get it and I try to write a program but It just doesnt want to come together. I have been reading about C++ on and off for years now and I understand fully what many of the functions and structural components of C++ are and how they work....but something seems to be flying right over my head! I scan thru these forums and hear talk about all different kinds of wacky functions and what not and have NO CLUE whats going on.. Does anybody have any suggestions as to where I might go for help/tips or some incite as to how they went about starting their coding career? Thanks in advance!

The best place to start is at the beginning.
Imho, the most difficult aspect of learning/teaching a subject has to do with mastering the basics. For it is during this phase that interaction between a student and the instructor is usually at its most intense. I suspect you're having difficulty grasping some of the fundamental concepts of programming, and rightly so. You can (relatively) easily teach yourself a new language, but understanding the basics requires a good instructor, a lot of hand waving, and eye contact.
That being said, I suggest you enroll yourself at a local university or community college and get a few computer science courses under your belt. Armed with the knowledge that you may have picked up reading and browsing this forum, you'll probably enjoy taking the courses more than some of your other classmates.
Here's a suggested curriculum. The actual course names may vary, but try to get this material under your belt.- Introduction to programming (logic, flowcharting, boolean algebra, C)
- Data structures
- Object oriented programming (C++, Java)
- Design patterns
Of course, simply understanding this material is not sufficient. You'll need to write hundreds of programs in which you apply your knowledge. That, imho, is the real process of learning.
Good luck and feel free to ask lots of questions!

Go to school. Also don't try to learn c++, maybe just the basics, e.g. syntax and try to get to newer technologies like vc++6 or .net languages... also don't just try to read about c++, try to actually make things with your knowledge because if you don't it will go as fast out of your head as it came in. Right now I'm studying directx and how to make games... if you think c++ functions are hard try directx functions in c++;P.

Hello, there,
I'd like to know how I can display tooltips on CToolBarCtrl when the CToolBarCtrl's window doesn't have focus. I put a CToolBarCtrl in a win32 window. But it won't display the tooltips when the win32 window doesn't have focus. I want the tooltip displayed even when the win32 doesn't have focus. When I move the mouse over the button, I can see the hot tracking, but no tooltips.
I noticed in IE window, the tooltips of links will show up even when the IE window doesn't have focus.
Thanks a lot in advance.

I inserted a ListBox in Form of CFormView and set it to Report type from the property. Using the control variable of the List Box the columns were inserted.
But while inserting Item using
int InsertItem( const LVITEM* pItem ); overload of the function, the call to LVN_GETDISPINFO is not sent and hence the items are not displayed.
the snippets of code
iteminfo *it = new iteminfo;<br />
it->Donum = m_donum;<br />
it->weight = allocate[i]/5;<br />
it->truck = it->weight/10;<br />
<br />
LV_ITEM lvi;<br />
lvi.mask = LVIF_TEXT|LVIF_PARAM;<br />
lvi.iItem = i;<br />
lvi.iSubItem = 0;<br />
lvi.iImage = 0;<br />
lvi.pszText = LPSTR_TEXTCALLBACK;<br />
lvi.lParam = (LPARAM)it;<br />
m_list.InsertItem(&lvi);<br />
i++;
and this being the LVN_GETDISPINFO message handler
void CTruckBillView::OnGetdispinfoList(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
LV_DISPINFO* pDispInfo = (LV_DISPINFO*)pNMHDR;<br />
CString string;<br />
<br />
if(pDispInfo->item.mask & LVIF_TEXT)<br />
{<br />
iteminfo *pitem = (iteminfo *)pDispInfo->item.lParam;<br />
<br />
switch(pDispInfo->item.iSubItem)<br />
{<br />
case 0:<br />
strcpy(pDispInfo->item.pszText,m_donum);<br />
break;<br />
case 1:<br />
string.Format("%.2f",pitem->weight);<br />
strcpy(pDispInfo->item.pszText,(const char*)str);<br />
break;<br />
case 2:<br />
string.Format("%.0f",pitem->truck);<br />
strcpy(pDispInfo->item.pszText,(const char*)str);<br />
break; <br />
}<br />
}<br />
<br />
*pResult = 0;<br />
}
Thanks in advance

Hello all. I am having a very hard time parsing a string that i am reading from a line. I have been working on it since 2 days ago and can not get it right...Here is my code. If anyone could take the time and see what my problem is, it would take alot of discomfort and stress from my shoulders.
Here is my function where i am reading from a file, which seems to be working fine. buff is a local variable that i have initialized as follows
char buff[256];
//reading a file
void CTimeTrackerDlg::ReadLine()
{
ismanager = false;
while( !m_sfile.eof() ) {
m_sfile.getline( buff, 256 );
parse_string();
}
m_sfile.close();
fileopen = false;
}
Now here is where i parse the string. I tried this code in a consoule application which seems to be working, but as soon as i place it in my program, MFC, dialog application, it seems not to work.
void CTimeTrackerDlg::parse_string( )
{
char temp[256];
strcpy(temp,buff);
MessageBox(temp,"temp");
CString p,n;
char * pch;
pch = strtok (temp," ");
int count = 0;
while (pch != NULL)
{
if(count == 0)
{
p = pch;
count++;
}
else
{
n = pch;
}
pch = strtok (NULL, " ,.");
MessageBox(p,"password");
MessageBox(n,"name");
}
}
Agan, any help or solutions would be greatly appricated

Example.
/* strtok example */
#include <stdio.h>
#include <string.h>
int main ()
{
char str[] ="This is a sample string,just testing.";
char * pch;
printf ("Splitting string \"%s\" in tokens:\n",str);
pch = strtok (str," ");
while (pch != NULL)
{
printf ("%s\n",pch);
pch = strtok (NULL, " ,.");
}
return 0;
}
Output:
Splitting string "This is a sample string,just testing." in tokens:
This
is
a
sample
string
just
testing
Also in "getline (char* s, streamsize n );" streamsize n mean Characters are extracted until either (n - 1) characters have been extracted.
Good luck.

Using hard-coded numbers in this fashion is just asking for trouble. Yours is a mild example, but imagine the troubles you'd have if the size of that buffer needed to change. You'd need to find all references to it. Use the sizeof() operator instead.

Which means?
What exactly are you tring to do? What is the format of the file that is being read? Mixing CString, char*, strtok(), etc makes me dizzy. That's way more than work than is necessary.

Awile ago, I had asked how to read the binary off of a CD. Alexander said that I would have to use an "IOCTL" (Thanks for your reply Alexander). Sorry, I am still quite new to MFC... What exactly is an IOCTL? Alexander said that the IOCTL to use is IOCTL_CDROM_RAW_READ. I think I have it defined in a header file called ntddcdrm.h. IOCTL_CDROM_RAW_READ is not a function, so I am assuming I need to use it in a function or something? If anyone could help me out, that would be great. Any help is apprectiated.

Search this forum for a post by longdafeng on 16-Feb. He includes a code snippet on how IOCTL_CDROM_RAW_READ is used with DeviceIoControl().

Hi all;
I am currently working on an application aimed at being a learning tool. Well, i'm sort of behind schedule and i need a quick means to render my project using an XP button and menu style. Can somebody please help me in finding the "magic" classes and on how to use them?
Thank you
Regards;

There's a number of companies that sell that sort of stuff. If it was widely, freely available, they wouldn't have a market, so I reckon you'll need to open your chequebook. I worked briefly for one years ago, but I can't remember the name. They advertise here on CP though.

Hello,
Homecome I dont see XP style buttons (i.e. XP visual style) when using a
local CHtmlview in an MFC app in both VC6 and VC7. I'm using a standard
manifest and DO have XP look in my app, but just not in the html-view... 
What I'm I doing wrong ?? Thanks alot for any reply !

I assume you are talking about buttons in the html itself. You could try adding: <META HTTP-EQUIV="MSThemeCompatible" CONTENT="Yes"> after the <head>
