MFC determines whether it should auto-center a dialog by comparing its RECT before and after your OnInitDialog() runs. (See _AfxPreInitDialog() and _AfxPostInitDialog().) If the RECT is the same before and after, then MFC centers it. If the dialog's default position is (0,0) then your SetWindowPos() call won't move it, and it will be centered.
You can either use another position, or call ShowWindow(SW_SHOW) in OnInitDialog() so _AfxPostInitDialog() won't do its auto-centering logic.

WOW, thanks Nice trick with this (0,0) window position;) Now it works fine. Thanks again

Use MoveWindow in OnInitDialog().

Hi all
The following code snippet....
ifstream f_;
f_.open(fname);
while(i < records_in_file) {
f_ >> data_[i].idx_ >> ws;
f_ >> data_[i].noOfRegs_ >> ws;
i++;
}
.. is reading the following file
0001 13
0002 24
0003 209
0004 85
0005 3
0006 122
0007 28
0008 9
0009 31
0010 27
… and so on …
All seems to work for the first 7 records, but when it comes to read the 8th record (i.e. “0008 9”), the first value it reads is 0 (zero) and then it reads the 8.
I can’t figure out what is going wrong. Any ideas? Is it something to do with ASCII screwing up the input stream.
As an aside I have also tried a “getline” solution, but run into similar problems.
Cheers

Any 'O' char (ASCII code 79) between zeroes?

No, I have copied/pasted from the above records (as they are zeroes) and also manually put in zeroes, but same result.
There are definitely 3 zeroes before the 8.

Can you please provide a code snippet showing the declaration of the variables?

Sure
In a header file
struct data {
int idx_;
int noOfRegs_;
} *data_;
.. and then later (in a function) ...
int records_in_file = 152;
CString fname = "..//Data//sta-f-83.crs";
data_ = new data[records_in_file];
// and this is what I posted earlier
ifstream f_;
f_.open(fname);
while(i < records_in_file) {
f_ >> data_[i].idx_ >> ws;
f_ >> data_[i].noOfRegs_ >> ws;
i++;
}
Thx

As a wild guess I'd say it's interpreting the numbers as octal due to the leading 0. 8 is not a legal octal digit so the stream stops reading after "000" which is why you get 0.

Thanks
So what do I do?

I don't know the stream classes well enough, I would guess that there is a function or manipulator that will make it parse numbers as base 10.

Use f_.setf(ios::dec) just befor reading values. For istance:
f_.setf(ios::dec);
while(i < records_in_file) {
f_ >> data_[i].idx_ >> ws;
f_ >> data_[i].noOfRegs_ >> ws;
i++;
}

Just quickly tried it - need to fully test - but looks good.
Thanks both. I owe you one.

Hi all,
my question is if I define a class myClass with destructor, assign operator (=) and copy constructor, etc etc.
If I later use my class like this:
myClass &a=*new myClass(whatever);
myClass &b=a;
Do I have to explicitly delete b? I've read you should only delete a class if you have instantiated it with a new. I know that behind the curtains b is created with a new call inside the dll, but do I have to delete it explicitly from my app?
thanks

since you've dynamically allocated memory for an istance of myClass, then you have to delete it somewhere. You can call either delete &b or delete &a (of course don't call both).

Ok thanks. That makes sense as I'm already deleting any pointers I need to inside my copy constructor.
Next step would be the assignment operator. Say for example y have:
myClass &a=*new myClass(whatever);
myClass &b=*new myClass(whatever);
myClass &c=a+b;
do I have to delete &c?
thanks for any replies.

IMHO you should not do this, because you're trying to assign a reference to a temporary object. For instance, the following is noy allowed(the compiler complains about):
int &i= *new int(5);
int &j=i;
int &k=i+j;
BTW: Doing some experimentation?

It is not illegal if you use a const reference.

Yeah, I didn't know it. Thank you (though seems rather clumsy...).

I would like to give a command from inside my program to do a File New command.
I tried pApp->CWinApp::OnFileNew() but it tells me I can't access a protected member.
Fair enough, but is there some system command I can give instead?
Thanks,
Ilan
