I want to create an app that runs in the background most of the time. On rare occasions I want to display a modeless dialog for a short amount of time and then dismiss the dialog. This all seems easy enough to do.
I would like some advice on how to place the focus back on the app or control that had focus before my dialog interrupted it.
Any high level suggestion would be helpful.
Thank you.

If you haven't switched to any other windows, then it'll happen automatically when the dialog box is closed. That's the way Windows works and I advice that you let it work that way.
If you want to override that behavior then before showing the dialog box, get the handle of the foreground window (using GetForegroundWindow) and then restore it when the dialog closes (SetForegroundWindow).
Cheers!

&group=earthweb.cgi.general&utag=
but in method POST URL doesn't show any infomation
I don't know what to do
Please help me ..... ( I'm sorry to post unrelate VC++ )
Thank you

Post Method depends on the reques header "Content-Length:"
to determine when is the data finished.
here is a telnet session to demonstrate how you may try it (After getting connected e.g. 127.0.0.1 port 80

Hello Ghazi
Would you mind give me an example please ....
cos I'm very new in CGI.
Thank you very much

The POST messages are sent by the Web Server as part of the applications environment variables. So you would use
routines like getenv to retrieve these variables.

Hi,
You can find descriptions of the GIF file format here:
http://www.wotsit.org/ (Graphics section)
Maybe you should first check if a new version of that library is available
(or maybe get another one 
Cheers,
Cristi

If you know how to parse the header section of the GIF file, then look for the 0xFF flag indicating an application-specific extension, and if found and you have a buffer, check for the string "NETSCAPE2.0" -- that's the indication for an animated GIF.

Is there somebody who has communicated with
serial port (RS485).
Any example would be great.
Thanks
|

RS-485 communication is actually exactly the same as RS-232 communication. Only the hardware is a bit different.
In WIN32, this is fairly easy. You use the COM port just like a file. You open the port with CreateFile and supply e.g. "COM2" as the filename.
You have to call SetCommTimeouts to specify the timeout values and SetCommState to specify baudrate, parity and the like. The you just call ReadFile and WriteFile for your communications and CloseHandle when you're finished.
When using RS-485, you will likely use the DTR/RTS mechanism. You can change the state of these lines by calling EscapeCommFunction.

==================
It depends if you have a card capable of driving RS485 installed on your PC. If you have you should be able to configure your interrupts on that card so that they may be on say COM3 or COM4. If you haven't got a card you can get a RS232 to RS485 converter and communicate through COM1 or COM2 on your PC's serial ports.

I use a National rs-485 card and the ports are used just like rs-232 as for as the win32 API
is concerned. So all standard serial port programming techniques apply. What specifically is
the problem? Any external devices attached to the rs-485 line always have their own specific
protocols, and you just have to get their manuals and do the work yourself.

Use a RS232/RS485 convertor and all the WIN32 API calls will work. U may have to set RTS control to RTS_CONTROL_TOGGLE for 2 wire operation.

Does a SHAppBarMessage wrapper exist? I would like to implement a ApplicationBar, and was just wondering before I go and write one myself.
Thanks in Advance

The best one I have found is at http://indigo.ie/~pjn/ntray.html
however I also think there is one on this site by Chris Maunder - investigate each and the decide for yourself.

Hi John,
There was a very good article on this topic in MSJ (it was published in 1996, unfortunately I don't remember the month). Anyway you can find the copy of the article on MSDN CD. You just have to search the library for: "SHAppBarMessage" or "Jeffrey Richter". The title of the article is "Extend the Windows 95 Shell with Application Desktop Toolbars"

How do I monitor browser activity such as Explorer Netscape and AOL etc like ICQ doe to get the current users URL?
TIA
Shaun Wilde

Attach to the iexplore.exe process and event sink to the web browser events. Then when the event occurs, like the url changing, you will recieve the event and can do what you want with it. There is an example on how to do this in an MSJ article back aroudn July 98
I also have experience doing this and could help you directly, just let me know.

I'm trying to create a static lib with a simple class
that has a single method that returns a std::string. I
can build the static library just fine but when I link
my application against the static library I get an error
about multiple defines of std::basic_string.
Has anyone done this successfully?
Thanks,
Brad
-------------------------------------------------------
My header file:#if !defined( __CTest_h__ )
#define __CTest_h__
class CTest {
public:
CTest();
~CTest();
std::string Try( void );
};
#endif
------------------------------------------------------
The corresponding .cpp file:
#include "StdAfx.h"
#include "CTest.h"
CTest::CTest(
void
) {
}
CTest::~CTest(
void
) {
}
std::string CTest::Try(
void
) {
std::string strResult = "testing";
return strResult;
}
--------------------------------------------------------
<string> is #included in StdAfx.h
