Hi,
The MFC Document/View Architecture has this facility.
For simple program with sending mail from File menu u can follow this method:
1 . Add a menu item with ID: ID_FILE_SEND_MAIL
2 . Add these to Application document’s message maps:
ON_COMMAND(ID_FILE_SEND_MAIL, OnFileSendMail)
ON_UPDATE_COMMAND_UI(ID_FILE_SEND_MAIL,OnUpdateFileSendMail)
Compile and Build.
Up On testing the default mail clients will be opened, u can even add an atachement to it.
Regards
jsk

For example you have 3 columns in your clistctrl
name idnum phone
----------------
ben 123 2335
alic 122 2334
then in your dialog you have
a CEdit were user can enter phone number
lets say 2334 the user hits the enter key
clistctrl will update with 2334 highlighted
thank you very much

Hello everyone!
I would like to ask how can we control (send commands to or read data from) USB ports/devices in Visual C++? Is it possible in Borland Turbo C++?
Thank you very much!

USB is not like a serial port. You cannot just open it and send data on it. You will need to write a driver which is 'linked' to a specific hardware. When connected, the hardware will send its VID and PID (vendor ID and Product ID) and this will allow the operating system to load the specific driver. The link between the driver and the ID's is made through an inf file that contains the information.
Then, once your driver has been loaded, your application can then 'call' functions from the driver.
Hope this helps

Why doesn't this work?
I made a dialog based application in MFC. When the program is launched, I want it to be hidden. I'm using a global keyboard hook to respond to a key press and restore the window. This part works fine. It seems that i can hide the dialog by putting ShowWindow(SW_HIDE); in a button handler. So.. it works if i press a button on the dialog but not when the program starts.
This code from Microsoft MSDN does not do anything. But it should:
/* MyDialog.cpp */
#include "MyDialog.h"
BOOL CMyDialog::OnInitDialog()
{
CDialog::OnInitDialog();
// TODO: Add extra initialization here
m_cMyEdit.SetWindowText("My Name"); // Initialize control values
m_cMyList.ShowWindow(SW_HIDE); // Show or hide a control, etc.
return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
I've read in so many places that by putting ShowWindow(SW_HIDE); in the OnInitDialog(), it will hide the dialog when the program starts. It doesn't do anything for my program.
But ShowWindow(SW_MINIMIZE) works in that location for some reason!!!!!!!!
Even by setting the dialogs extended properties in the resource manager (unselecting the Visible checkbox), doesn't do anything.
If i put the ShowWindow(SW_HIDE); in the application's initialization (before the command to CMyDialog.DoModal()), I get an exception message "Debug Assertion Failure"!! Why?!!??!!?!?!??

hey
I want this function to return the location of the first letter of a substring in the searched string
int subsrc(char *target[BL], char *pattern[BL])
{<br />
if (strlen(pattern)>strlen(target))<br />
return NULL;<br />
int first_i;<br />
for (int i=0;i<strlen(target)-strlen(pattern);i++)<br />
{<br />
int j=0;<br />
if (target[i] == pattern[j])<br />
first_i = i;<br />
while (target[i] == pattern[j])
{<br />
i++;<br />
j++;<br />
if (pattern[j] == NULL)<br />
return first_i;<br />
}<br />
}<br />
return NULL;<br />
}
thanks dudes

What about strstr function!

Each of these functions returns a pointer to the first occurrence of strCharSet in string, or NULL if strCharSet does not appear in string. If strCharSet points to a string of zero length, the function returns string.
i SUCK with pointers so help me out here
how would I know what number of the array it would be?
thanks

Thats What strstr function defined in string.h do.
Is you have to code your own function for that?

What would be the best way to extract something between two substrings?
Like if I'm looking through HTML code and i want whats between <tag> and </tag>
from:
"<tag>$20.00</tag>"
i would want to extract "$20.00"
but it could be anything

Hope this code work well for you!
BOOL CViewSource::Return_Element_Value(const char *lpszOriginalString, const char *lpszElementVar, char *lpszReturnValue)
{
char csOpenTag[20],csCloseTag[20];
int start_pos, ending_pos, closing_br;
int i,j;
char *pdest;
sprintf(csOpenTag,"<%s>",lpszElementVar);
pdest = ::strstr(lpszOriginalString,csOpenTag);
start_pos = pdest - lpszOriginalString + 1;

for(i=closing_br-1,j=0;i<ending_pos-1;i++,j++)
temp[j]=lpszOriginalString[i];
temp[j]='\0';
strcpy(lpszReturnValue,temp);
return TRUE;
}

Some simple pointer arithmic will do your magic:
char* pszYourString = "This is some string";
char* pszPattern = "some";
char* pszDest = strstr( pszYourString, pszPattern );
int nPos = pszDest - pszYourString + 1;
Look in MSDN[^] for more information on strstr

There's no need to add one to the result. Doing so creates an off-by-one error.

Well, the + 1 is there in MSDN..  This position in this case, is not the zero based index to an array, but the position starting at 1.
Do VB or Pascal have zero based indices?

For VB, it depends on Option Base. Yes for Pascal.

Nope, Pascal don't have ZERO based Index, Index of array in pacal start with 1!

Actually it does:
program abc;
var
numbers:array[0..9] of integer;
x:integer;
begin
for x:=0 to 9 do
numbers[x]:=x;
end.

I have done pascal in First Year of my Engg Graduation. When I convert from pascal to C++ , i always face problem due to array INDEX as Pascal Index start from 1 and in C++ index start from 0. May be you are right, I havn't learn PASCAL much

I am bit concerned over the issue of fragmentation problem due to dynamic memory allocation in real time applications that have to run for long say 1 year. How to avoid it? What if in some scenario you must dynamically allocate the memory occasionaly of different block size?
Any one here, who has developed some performance critical application which runs for long and have addressed these issues?
Thanks
