Hi CPallini,
Please ignore the code in main. 
I mean the code outside main.
Let me clarify my question,
1. my question is whether the below understanding is correct?
I think the purpose of such struct definition is, defining struct and a
variable of the type (in this sample type tFoo) altogether
2. any other benefits of using such type of definition?
regards,
George

Hi,
I'm trying to read a file which contains lines like "0.14779E+02".
A made a function which return a vector\<float\>.
std::vector\<float\> readData() {
std::vector<float> fResult;
CString dataFile = _T("C:\\d2.txt");
std::ifstream input(dataFile);
if (!input) {
MessageBox(0, L"input file cannot be opened", L"error", MB_OK);
return fResult;
}
std::string c;
float fLesen;
while (!input.eof()) {
std::getline(input, c);
fLesen = atof((const char*)(LPCTSTR)c.c_str());
fResult.push_back(fLesen);
}
input.close();
return fResult;
}</float>
Every time I'm trying to print out the float with something like that:
std::vector\<float\> lines = readData();
for (int i = 0; i < sizeof(lines); i++) {
CString a;
a.Format(_T("%f"), lines[i]);
MessageBox((LPCTSTR)a, L"error", MB_OK);
}
the variable a is emtpy.
What am I doing wrong?
Thanks in advance.

Have you run this in the debugger to see why?
Opa Knack wrote: for (int i = 0; i < sizeof(lines); i++) {
sizeof gives you the size of an object, not the number of elements in the vector.
Try
for (vector <float>::size_type i = 0; i < lines.size(); i++)

In the debugger I can see that 'lines' has the expected values stored in float format.
It's just that the MessageBoxes are always emtpy.

That must not be true.
I tested your code like this:
std::vector<float> lines;
lines.push_back(1.00);
lines.push_back(2.00);
lines.push_back(3.00);
for (vector <float>::size_type i = 0; i < lines.size(); i++) {
CString a;
a.Format(_T("%f"), lines[i]);
MessageBox(a, L"error", MB_OK);
}
and it works fine.

Use CString::ReverFind alongwith CString::Right or CString::Left to extract the string you want.
Somethings seem HARD to do, until we know how to do them.

CString str = "http://server/sharanu/inbox/test.jpg";
int i = str.ReverseFind('/');
str = str.Left(i);
CString sValue1 = str.Right(str.GetLength() - str.ReverseFind('/') -1);
i = str.ReverseFind('/');
str = str.Left(i);
CString sValue2 = str.Right(str.GetLength() - str.ReverseFind('/') -1);

How do I go about entirely disabling a Tree View's selection? I want my app to focus on a node via the user's mouse and not by the default of the keyboard selection. Otherwise, the keyboard selection does not follow the user's mouse clicks.

Hi,
I have a custom ListCtrlEx which embeds a combobox in it. When the selection of combobox changes I am sending a user defined message to its parent(ListCtrlEx here) using GetParent()->SendMessage() and from ListCtrlEx again to its parent that is the dialog box(here) and handling the message there for identifying the changed row and coloumn. Now my query is if I use 2 ListCtrlEx controls in one dialog box, How do I identify from which ListCtrlEx I got the notification from?? Whihc parameter should I pack in WPARAM so I can uniquely identify the ListCtrlEx which send the message.
Any help would be appreciated.
With Reagards

the ID or the window

You may use either the ListView control ID or its window handle.
