No, I didn't. I posted a reply, I remember it clearly.

1. If you encounter an exception, it will close the file and flush the buffer first.
2. I don't see any examples that help me here - is the fopen stuff able to stream all sorts of data types ? I notice the examples in MSDN are not valid C++, they have void main 
3. I am certain that the C style file stuff does not allow me to define my own custom stream, stream my own custom types, or provide my own modifers. Does it have modifiers at all ?
4. I just found some docs and fprintf, if it's the only way to write numbers, etc. has to qualify for one of the most ugly and hard to debug constructs I have ever seen.

1. ok, that's handy.
2. fwrite takes a void * pointer, data types are meaningless.
3. this is apples and oranges. with fopen, you get (or put) a stream of bytes - break it up however you like.
4. yes, we know you don't like printf formatting but, for many people, it just feels right.
ok. so i can see how coming from iostreams to C I/O would seem ugly and primitive. but, from the other direction, iostreams seems fluffy and prissy.

Damn straight !!!

I guess so. And I guess I'm a hypocrite for decrying C# as too prissy in favour of C++, but in the end, it's all the same, we're all creatures of habit, aren't we ?

You know, just recently I did use your iostream article to read and write to a richtextbox which was giving me garbage when done with fread. Then I totally forgot about it, since I dont do too much of file IO. Thanks for the reminder. Wont hurt to re-read the article again either
Thanks,

I'm making a W32 image viewer dialog and I resize the window according to each picture dimension.
I've got a problem with the scroll bars as their dimension is part of the client area. Thus I have to get the Horz. ScrollBar width in order to resize correctly.
I would also need to know if the scroll bar is visible or not in order to hide/show it only when necessary.
I found the GetScrollInfo and GetScrollBarInfo that could help me solve those 2 problems but they only are an indirect way to get the informations I need.
Is there a better API way to:
- Get the width/Height of a scroll bar
- Know if a scrollbar is shown/Hidden
The answer would probably be the same under MFC but I can't make a MFC dialog for thsi project.
Thanks

If you're just using WS_HSCROLL/VSCROLL, the scrollbars are not part of client area.
Use GetSystemMetrics to get the scrollbar height/width.

Hi Tomasz, I just found your reply today while lurking through this forum. THnak you for your reply. Fortunately I recalled the GetSystemMetrics function this week end but I'm still very intersted by your answer.
Yes, I'm just using those 2 styles, and that's true they are not part of the client area - there's a not missing here. Is there any style that would include the scroll bar size within the client area ?

No. If you need scrollbars *within* client area, then you have to abandon WS_HSCROLL/WS_VSCROLL and place scrollbar controls yourselft. Note that this will require repositioning them in WM_SIZE.

Ok, then I can live with the WS_*SCROLL scroll styles. Adding a scrollbar control would be of no benefit to me.
I was very surprised last week when after resizing my client area I found it had the proper size minus the H. scroll bar width. All is clear now. I'm a Borland CBuilder programmer at the origin - now moving to MSVC - that's why I've still a lot to learn about the GUI API.
... and that's why I need a W32 Window, my project is still half CBuilder, a quarter MFC, a quarter W32. Very Interesting too to mary those techniques but somtimes a bit messy 
Thanks

GetSystemMetrics() SM_CXHSCROLL, SM_CYHSCROLL, SM_CXVSCROLL, SM_CYVSCROLL will tell you the dimensions of the scrollbars.
In ED I keep my own flag which tracks whether a scrollbar is visible or not. However these are scrollbar controls as they are used in splitter windows and you are probably using the windows builtin scrollbars.

Hi.
I would like to know a way to correctly cast a string object to LPSTR.
I have an LVITEM structure for a CListCtrl.
-----
string szText = "testing 1 2 3";
LVITEM item;
...
// Compiler does not allow this kind of typecasting.
// Note "testing 1 2 3" alone is not an option. I can
// use a string and/or CString object or allocated
// new memory and then copy the data from szText.c_str()?
item.pszText = szText;
-----
How do you get the line above to work? I have tried using a CString object, but the compiler kept responding with an error about LPSTR.
Thanks,
Kuphryn

item.pszText = (LPSTR)(LPCTSTR) szText;
or
item.pszText = szText.GetBuffer(0);
And I swallow a small raisin.

You cannot. std::string does not have a method to get a non-const pointer to the data. Use a CString and GetBuffer().

I saw members recommending CString.GetBuffer() and double casting (LPSTR)(LPCTSTR)(CString). Is there any advantage to using GetBuffer() and/or casting?
Kuphryn

Do the following:
item.pszText = myCString.GetBuffer(iWhateverSizeIsNeeded);
myCString.ReleaseBuffer();
or
item.pszText = (LPSTR)(LPCTSTR)myCString;
if you're looking for trouble.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

That code is patently wrong. The fact that it compiles (because the casts override type checking) and that it even runs (because the buffer just happens not to be modified) does not make the code correct. Sure, it may work in the first situation you try it, but if you make a habit of doing so, it'll eventually break with some other API and you'll be stumped as to why the code "suddenly doesn't work".

I will use CString.GetBuffer() and CString.ReleaseBuffer().

I am using EnumWindows to enumerate all windows till it finds my target window (which in this case is an instance of IEXPLORE.exe, Internet Explorer). Once found I use the Handle to the window and then do ShowWindow( hwnd, SW_HIDE).
My routine works for all targets/applications I have tested so far except for Internet explorer. I manage to find the window, but when I issue the ShowWindow(SW_HIDE) for it nothing happens. The browser just stands there and stares at me. 
Any ideas?
Thanks

Can you MoveWindow() the window? If so, you could try moving it to (-32767,-32767) in lieu of hiding it.

Well apparently the reason it does not work is that I am creating an Instance of IE using CreateProcess. I retain the processID, which I then use to find the HWND using EnumWindows. Apparently the HWND that I obtain is not that of what we see as IE. I tried something similar to what you suggested, I did SW_MAXIMIZE instead of SW_HIDE and the entire screen became white. Obviously another window that I maximized. So IE is probably run through another parent process the window to which is always hidden (and the handle to which I get from EnumWindows) or something like that. What a pain!!!!!
So now I need a way to find the HWND for the main IE window that we see and use. Any suggestions?
Thanks,
Ranjan

Ugh, that's nasty. 
Off the top of my head, the only cheesy solution I can think of is to use EnumWindows() to find all top level windows, and check the caption of each for "Microsoft Internet Explorer" (of course this won't work on non-English systems). For every match, get the process id to which the window's thread belongs and see if it matches the saved process id. I'd have to investigate to see how to do that last part. Sorry, I know I'm not being too helpful!
