Ditto on CPallini's reply.
Maybe store the rects in a GraphicsPath and use that to make a
Region when you need one...

I have an edit control that takes up the majority of space on my app. I am receiving continuos data from a port and would like to display each message separated by "\r\n".
I tried using the control variable and the value variable for my edit control to display these items. No matter what i try , it only displays the first item and not the rest.
I have used the method "SetWindowText"
I also use UpdateData(FALSE) to update the screen
How does one use these vars to display the continuos data in an edit control?

Isn't a list control (a list box or a list view ) more appropriate, is it?

How are you doing this?

I simply have a control variable for my edit control
call it m_Control.
I have a string variable for that same edit control.
call it m_strValue.
I do something like
//using the string var
for (int lop=1; ;lop<100;lop++)
{
m_strValue = data[lop];
UpdateData(FALSE);
}
///////OR
for (int lop=1; ;lop<100;lop++)
{
m_Control.SetWindowText((LPCSTR)data[lop]);
UpdateData(FALSE);
}

Neither of these will preserve what is currently in the edit control.
LCI wrote: m_Control.SetWindowText((LPCSTR)data[lop]);
UpdateData(FALSE);
When using a CEdit control, or any other time for that matter, UpdateData() is not necessary.
You can do something like:
for (int lop = 1; lop < 100; lop++)
{
CString str;
m_Control.GetWindowText(str);
str += data[lop];
m_Control.SetWindowText(str);
} Or you could just continually add to the end of the edit control as has already been suggested.

Since you are trying to update a window while you are in a tight loop, you need to realize that the window will not process any messages until the loop completes. The UpdateData puts a message in the queue to be processed, but it isn't processed immediately.
To overcome this, try
for (int lop=1; ;lop<100;lop++)
{
m_Control.SetWindowText((LPCSTR)data[lop]);
UpdateData(FALSE);
m_Control.UpdateWindow();
}
The call to UpdateWindow bypasses the normal message queue and causes the window to repaint immediately.
Hope that helps.

Do you have the textbox set to multiline?
Or use a listbox as was mentioned.
Why is common sense not common?

From MSDN (here[^]):
So, set the current selection (SetCell) to the last character and then replace the current selection by the new text (ReplaceSel). This way, you don't erase what was there previously.

How would you do it manually (without a computer) ?
Start by putting all numbers in a bag, then pick the first number; this can be considered the minimum value.
continue picking numbers, if the number is smaller than the current minimum value, then it becomes the current
minimum value; continue with the rest of the numbers.

Hint: write a function accepting as arguments an array of numbers and its element count.
BTW if you want to feel the thrill of a more advanced context, have a look at http://support.microsoft.com/?scid=kb%3Ben-us%3B156619&x=12&y=14[^]

Put your numbers in a text file of some sort (e.g., num.dat). Create a console application using:
void main( void )
{
int nNumber,
nMin = INT_MAX;
while (fscanf(stdin, "%d", &nNumber) != EOF)
{
if (nNumber < nMin)
nMin = nNumber;
}
printf("Min = %d\n", nMin);
}And then type one of the following at a command prompt:
type num.dat | prog.exe
prog.exe < num.dat

Great!
But I think he can keep things simpler if:
(1) Creates a database engine, i.e. MySqlEngine.exe.
(2) Creates a database and a table, namely MyNumbersDatabase and MyNumbersTable.
(3) inserts the numbers into the NUM column of the MyNumbersTable table.
(4) issue an SQL query such as SELECT MAX(NUM) FROM MyNumbersTable

Then specify two (different) light blue tones for both the starting and ending color.
What is the difficulty about?

Hi all,
I am working on a VC++ project using VS2003 which comprises of several nested namespaces, classes, and type definitions. I have a problem which I really do not understand, as far as I am aware, this SHOULD work 
This Works:
<br />
namespace Root<br />
{<br />
class MyClass<br />
{<br />
public:<br />
MyClass(int input = Nested::TemplateClass<int>::constant_value);<br />
...<br />
};<br />
};<br />
But this DOESNT
<br />
namespace Root<br />
{<br />
typedef Root::Nested::TemplateClass<int> NESTED_CLASS;<br />
<br />
class MyClass<br />
{<br />
public:<br />
MyClass(int input = NESTED_CLASS::constant_value);<br />
};<br />
};<br />
Compiler Errors (Edited, forgot to post originally)
Sorry, I meant to have pasted the compiler errors . Here they are:
error C2065: 'constant_value' : undeclared identifier
error C2653: 'TemplateClass<int>' : is not a class or namespace name
The project that I am working on is very big, and has a lot of files. I am unable to reproduce the same problem in a simple test project.
Does anybody know what might be the cause of this weird problem?
Cheers!

IMHO one of the points is: do you really need such a mess?
