This is an MS bug, Q253317. It can safely be ignored, as I have been doing so for years. The quickest way to avoid seeing it is to change your import statement to the following:

#pragma warning( push )
#pragma warning( disable: 4146 )
#import "c:\program files\common files\system\ado\MSADO15.DLL" no_namespace rename( "EOF", "EndOfFile" )
#pragma warning(pop)
</code>

_ftime64

I'm using _ftime64(__timeb64) to obtain the system time. but when compiling, I receive "unknown identifier"-errors.

include files (found on msdn):
#include "time.h"
#include "sys/types.h"
#include "sys/timeb.h"

code (found on msdn):
struct __timeb64 timebuffer;
char *timeline;

_ftime64( &timebuffer );
timeline = _ctime64( & ( timebuffer.time ) );

Have I forgotten an include file? Confused | :confused:

Is there a better way? Blush | :O

tnx

I'm not sure it's actually a better way, but you need VC.NET for ctime64. If you prefer to use VC6, then ctime (without 64) is your only choice.

I don't have .NET, so ctime it is. Wink | ;)

one more thing:
The msdn-doc says this about ftime: All versions of the C run-time libraries.

Isn't that correct information? They refer to 64-free version.

Try this - from my CSimpleDate class here on CP:

<br />
{<br />
   	long time_val ;<br />
   	struct tm *tm_ptr ;<br />
<br />
   	time( (time_t *)&time_val) ;<br />
   	tm_ptr = localtime( (time_t *)&time_val) ;<br />
<br />
	m_Hour=tm_ptr->tm_hour;<br />
	m_Min=tm_ptr->tm_min;<br />
	m_Second=tm_ptr->tm_sec;<br />
	if(m_Hour >= 12)<br />
	{<br />
		m_bPM=TRUE;<br />
		m_Hour-=12;<br />
	}<br />
	else<br />
		m_bPM=FALSE;<br />
}<br />

Icons to use in an MFC project

Wim Jans11-Sep-02 1:47

So, where do you guys get your icons for your application?

You go to msdn and get them over there?
You have an in-house artists who creates them?
You downloaded a nice collection of the internet? url?
Or you just open an executable and take the icons from there. If so, what program can you use to extract that nifty looking 256-color bitmap icons out of an executable.

And finally, are the icons I take from eg. shell32.dll royalty free?

My graphic ability is a bit on the low side Wink | ;)

Thanks in advance

You can use Visual Studio. In file open dialog, select "Resources" in Open as combobox.

Its amazing how much good icons can improve your application.

I used to spend ages making, what in the end turned out to be pretty crap, icons.

check out www.glyfx.com, they have a free version of the typical icons available with VC++ but you can pay them for more advanced icons.

or if you feel adventurous try out

CharWidth

How can I get the width of a char in a view(in pixels). It seems to be difficult for me coz each chars width will be different

Re: CharWidth

Pavel Klocek10-Sep-02 23:59

GetTextExtent or GetTabbedTextExtent API functions or correspoding methods of CDC in MFC.

Since I want the char size in OnChar function itself, i cannot use GetTextExtent API. I have the log font size stored in a variable. But it is in logical units. I want to get the pixel size.

You can use CWnd::GetWindowDC/ReleaseDC to get/release a display context of the window.

Access to a driver

Anthony B.10-Sep-02 20:33

10-Sep-02 20:33

I need to use a device driver (developed by a colleague of mine)
in my application that runs on WINNT and I have the following problem:

I can access to the driver (CreateFile and OpenEvent) only if
I'm logged with an Administrator user.
Non-administrator users cannot access to the driver even if it
starts automatically with the OS.

Is this a normal situation or can I do something to allow the
application to access to the driver even if it is used by a
non-Admin user ???

Re: Access to a driver

I assume you checked the return code for the failed CreateFile() and it was #5 (access denied). If so then the most likely problem is the device driver was installed requiring admin privs to connect to it. Check the install.

What's that thingy called?

I'm trying to add one to my app. If you're not sure what I mean, open Windows Explorer and make the left pane much wider, which results in a now shorter right pane. What the heck is that thing called that lets you do that? The closet I've come so far is "Rebar control" and that seems to only apply to the one control it's attached to.

I'm attempting to add one to my app using C++ through the API, so if you can step up and play "Name That Control" I'd appreciate it. No MFC references please.

Well that definitely gave me an anchor point for my searches, but I'm looking for the direct Win32 API calls I need to make, not the MFC ones. Perhaps if I knew of a good MFC reference that detailed the underlying API calls things would be much easier on me, but I don't.

Splitters are not a built-in control, you'll need to code them yourself. For a good reference, check out MFC Internals which goes into painstaking detail on MFC's splitters.

CFileDialog MULTISELECT

Hi Gang,
I was wondering if anybody has a sample of a CFileDialog where I can select more than 12 items. It reliably selects 12, just nothing more. When more are highlighted, it just returns nothing. Any ideas?

Env: VC6,sp5,XP/SP1

Thanks,
Nick
