My hunch was strangely accurate. If you look at the constructor for CFontDialog in MSDN, it has a sample (reproduced below) that sets a negative value (the pixel height) into lfHeight, not 1/10ths of a point as you have:
// Show the font dialog with 12 point "Times New Roman" as the
// selected font.
LOGFONT lf;
memset(&lf, 0, sizeof(LOGFONT));
CClientDC dc(this);
lf.lfHeight = -MulDiv(12, dc.GetDeviceCaps(LOGPIXELSY), 72);
strcpy(lf.lfFaceName, "Times New Roman");
CFontDialog dlg(&lf);
dlg.DoModal();
I believe this to be the source of the problem.

Hello to everyone interested!
I am willing to write an application for my Pocket PC which should use the (built in) Bluetooth to 'upload' a .txt or .xml file. If it's possible, I'd like to do that with minimal user intervention on the PC.
Just turn on Bluetooth ports on both devices, select 'upload file' on PPC and the PC to accept it.
If you have any idea about this, any article related to my problem or something to start with, I'd be deeply thankful!
Best wishes!
if someone would like to contact me, here is my email: shpid3r@yahoo.com

Hi, I am reading in a line from a .dat file using fgets. The line is an unknown number of variables written in scientific notation (4.20000e+00 1.00000e-01 1.177000e+00 0.000000e+00 ...). The first two are an x and y location and will always be there. Due to the number of these lines to read in, minimum is 500000, I don't want to use char/string as each number will take about double the memory of a float. Using sscanf with a large amount of %f I can find the number of variables (there may be up to 30).
int number = sscanf(data_in,"%f%f%f%f%f%f%f%f%f%f%f...",&temp[0],&temp[1],...,&temp[n]);
With number I can create a string with the correct number of '%f' and set the array to the correct length.
At the moment I use a full array of 30 with the correct number of %f. Knowing how many variables there are I can pull only the valid elements from the array.
I am stuck on how to set the number of references '&temp[n]', to match the number of %f in the format string.
Any ideas on how to set everything equal lengths would be greatly appreciated.

How about
std::vector<double> numbers;
std::stringstream str;
str <<< data_in;
for ( unsigned i = 0; i < number_count; ++i) {
double d;
str >> d;
numbers.push_back( d);
}
You will end up with number_count doubles in the vector numbers.
You will need to improve the error checking, and you might want to use iterators here, if you feel fit.
Also, boost::lexical_cast[^] could be used to make this more programmer-friendly.

What about using a loop?
int max = 30;
for( int n = 0; n < max; n++ )
{
sscanf( data_in, "%f", &temp[n] );
}

CFile::GetStatus(filePath, fStatus) works fine with local files, but does NOT work with remote shared files when accessed by UNC.
Any ideas on how to access/read/write remote files from MFC C++ apps would be greatly appreciated?
Thanks in advance.

Unless I misunderstood your question, this works fine for me:
CFileStatus stat;
CFile::GetStatus(_T("\\\\machine\\share\\boot.ini"), stat);

Put the tab order in the sequence.( to see the tab order take the dialog in the resource and press ctrl + D ).
|
|
|
|
|
...and start every group of button with the group property.
Tip: in resource view use Ctrl+T and Ctrl+D and look and click (to sort) :->

As long as you put them in the proper z-order and use the WS_GROUP style correctly, this is how they are supposed to behave.
