Re: Equivalent of LineScroll for CStatics?

Wait - what do you mean by 'text cursor'? A caret? This blinking | thing? In this case, you'd have to probably handle WM_SETFOCUS (or EN_SETFOCUS) and call HideCaret.

Yes, I refer to the | blinking thing. I've finally found a solution: it doesn't involve handling those messages, but rather cheating the system with the enabling/disabling thing by handling WM_ENABLE. I found this trick here[^].

Thank you very much for your efforts. Keep the good work helping people here at CP!

I'm not to sure there is a way to do this easily, Basically within my OnWizNext I validate data, if this fails, I want to drop out of the wizard process for the user to modify data. I was hoping to be able to call OnCancel() however this doesnt work, has anyone any ideas?

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.

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

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 />

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

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

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.
