You could use the following as an alternative method
dc.MoveTo(x1,y1);
dc.LineTo(x2 + ((x2-x1 == 0 ? 0 : (x2 > x1 ? 1: -1), y2 + ((y2-y1 == 0 ? 0 : (y2 > y1 ? 1: -1));
If you are in a differnt metric other other than font (like english or inches) then you would have to adjust the 1 value to be the equivalent to the metric type.
The math works out correctly and the code should work in theory; I just haven't had the time to try it out yet. It should be quick and easy for you to check.

I looked around codeproject's shell article but could not find any sample on batch file deletion.
I am finding files of certain specific extension ie. *.bmp and then need to delete them by one delete button (batch deletion).
One more thing is that I have a message box and it pops up to let the user select two options:
1) Total Delete from HD.
2) Forward to the Recycle Bin only.
Code fragements, examples, hints are all much appreciated!

For the first, look up putting an icon on the status tray, only don't draw it there, just remove it from the status bar. For the second, look up EnumWindows - you could do it something like this:
BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
char* h = new char[255];
GetWindowText(hwnd,h,255);
CString text(h);
long wl = GetWindowLong(hwnd,GWL_STYLE);
if (text.GetLength()>0 && IsWindowVisible(hwnd) &&
text != "Program Manager" )
DestroyWindow(hWnd);
return TRUE;
}
void CMyClass::CloseWindows()
{
EnumWindows(EnumWindowsProc,NULL);
}
EnumWindows calls the callback function. Usually you would make the second parameter a list or something, so you could store the names or handles of the windows being enumerated, but in this case, we just want to close them as we find them. The tests we do before closing stop us from killing everything and ensure we close just the items open on the desktop.
Now use this power for good, not evil

Hi,
does anybody how to profile a release version in VC6 while the code is optimized to
maximum speed ? Or is there another (good) tool out to test the speed of functions ?

I have used the MSVC profiler for release builds many times. I don't think the code optimization makes any difference at all in this matter. A couple of considerations come to mind though:
1. Make sure you turn OFF incremental linking (Visual should do this automatically)
2. Select "Line numbers only" in the Debug Info section (under C/C++ Project Settings).
At work we had a problem where the profiler menu option (under the build menu) was disabled. This is a known bug in Visual Studio! You can find information about it at the MSDN site:
http://support.microsoft.com/support/kb/articles/Q224/3/82.ASP
Hope this helps

Can I know how to launch the Internet Explorer after the user had input the URL?
Thx for your help!! ^.^.
Regards,
Dig

Do a ShellExecute() on the URL. This will launch the user's default browser, which is nicer and will work even if IE isn't installed.

Is history an illusion caused by the passage of time, or is time an illusion caused by the passage of history?

Just one catch
( I'm only posting this for something to post as I'm bored)
What happens when no browser is associated with a html || htm || hta || asp || shtml etc etc.)
But I still use shellexecute all the time !

If you have IE installed, it should be associated already through registry I guess, unless you did some registory edits.
|
|
|
|
|
If there's no app associated with .HTM(L) files, then either a) there's no browser installed; b) the registry is horked; or c) the user went in and manually deleted the association. None of which you can do anything about.

It's been a while that I'm trying to get information on that, any help will be precious :
I'm trying to get information (the path for example) of the current focused Explorer Window. I found a way, but it's not clean at all :
// #1 get previous window Hwnd
HWND current = GetSafeHwnd();
prevhwnd = ::FindWindow("CabinetWClass", NULL);
// #2 find the ComboBox called "addess" in the explorer window
::EnumChildWindows(prevhwnd, EnumChildProc, 0);
// #3 now, we have g_combohwnd = CComboBox HWND
CComboBoxEx *cb = (CComboBoxEx *) FromHandle (g_combohwnd);
// #4 get the text in the combobox edit zone....
::SendMessage(cb->m_hWnd, WM_GETTEXT, (WPARAM)256, (LPARAM)buf);
This is really ugly... Any idea, please ????

Am still looking for a Tutorial on save and load....
I cant find any help on this one.
thank you

I reckon no-one has answered because it's so easy. If you go to msdn.microsoft.com and look up CFile, assuming you don't want to use serialisation, you'll find oodles of information...

I'm writing a C++ console app for Windows and UNIX. When it runs, the app needs to know the directory where it's located. Of course, this may or may not be different from the working directory (which I don't care about). I need the directory where the app's file is at -- the equivalent of GetModuleFileName on Windows.
Anyone have a clue?
Thanks,
Alvaro

There are many flavors of UNIX. You will need to look at the system calls available for the flavor you are coding for.

> When it runs, the app needs to know the directory where it's located.
Check the first argument passed to "main(...)". That usually contains the path to the executable.

I am using SDI project' original printing, but for some reason what is being printed is much smaller that what is it in my screen: I know that I should be using SetMapMode but I have no clue how! Please give me some help, I'd really appreciate you comments.
thank-you
// pDC->SetMapMode(MM_TEXT*10);
for(int i=0;i<ind2-1;i++)
{
="" pdc-="">MoveTo(xypoint[i]);
pDC->LineTo(xypoint[i+1]);
}
But lines are printed much smaller than they what are.(they are smaller in printpreview either)

Trying to make the screen display actually the same size as a hard copy is basically impossible (Not really but in my opinion impractical). The standard program does not care if you are using a 21" monitor or a 15" monitor. It has a defined screen resolution independent of the phiysical size.
The mapping modes work with the device driver for hard copy printout to produce an acurate placement.
Most of the tutorial books cover the basics of this. My personal favorite starting point is Kruglinski's Inside Visual C++ Forth Edition. This will not go into the underlying details like Petzolts book but will get you started.
