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.
==================
The original message was:
Is there somebody who has communicated with
serial port (RS485).
Any example would be great.
Thanks

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

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 {

For one, you aren't directly including the <string> header file as far as I can tell...that might have something to do with it. Of course, it might just be easier to use CString instead of string (it is what MFC uses anyway and it basically offers the same functionality).

That should read you aren't directly including the < string > header file

Sorry the '<' & '>' in my orriginal post were
treated as html; < string > is #included in the
stdafx.h.
1. I do not use 'using namespace std' because that
I want to use the namespace and not just ignore
it, therefor I scope all of the stl strings with
std::. This works very well.
2. I am not using CString because I don't want to
use MFC for this and because I am using string in
this example when I also want to use stl vector
and map classes.
3. No one has addressed my original problem which is
multiple defines. The code for the static library
builds just fine. I am getting the multiple defines
in the application that also uses stl and links with
my static library.

In your stdafx.h put the following
#include <string>
using namespaces std;
the second line allows you to just make your declarations like so:
string strmystring;
string = "This is a string";

I write a lot of "smallish" custom C++ apps and am always interested in understanding the actual amount of time spent on each project. (Perhaps similar to the File-Properties information provided in Microsoft Word.)
Is there a DevStudio Add-In that tracks time in a project/workspace? If not, I'd be interested in other (preferably automated) approaches.

I don't know if there is an add-in, but it wouldn't be that hard to write yourself a quick little program that tracks the time (select the project from a dropdown list or something and then hit the start button to start tracking, hit the stop button when you go on break etc.). It might take 15 minutes or so to write.

I think he means something different.
No everybody will remember to press the buttons.
It should work automatically - when your open a project it should start, when you close - finish. Also take care abourt right counting time while your another application is active and VC++ is sleeping

That wouldn't be much harder. Just enumerate the windows to search for a title contianing "Microsoft Visual C++" on one of them, and then store the window's HWND value and use a thread to constantly check the status of the window and update the time (maybe every minute or so, so that it doesn't take up too much proccessor time...or every 5 seconds or so...it all depends on how accurate you really want to be). The title comes in something like the following format: "PROJECT NAME - Microsoft Visual C++ [CURRENT FILE INFORMATION]". When the PROJECT NAME part changes, or the window is closed, or the window and its children are not active, the clock stops counting for the listed project. On program exit and entrance, it would load past project values and save new project information. A simple combo-box interface could allow you to view the status of each project, reset timers, etc.

Sure is not so difficult.
Rather it can be done by way automation - throw Application object.

Hello,
just a beginner question:
I need to write a small application which does the following:
1. Loads a colored *.tif file
2. Removes the red color completely from the image
3. Saves the image as a black and white *.tif file
How do I go on about this?
TIA
Best wishes,
Matthias Steinbart

Oh oh...
You can try to use the Image Packet from Data-tech, www.data-tech.com, or you can try to search code that loads Tiff ( oops !).
Good luck !

Try
http://www.paintlib.de/paintlib/
There you will find a free library that appears to be fairly complete. To quote from the site:
"paintlib is a portable C++ class library for image manipulation. Images can be loaded from PNG, TGA, TIFF, JPEG, BMP, PCX and PICT files and saved in TIFF and JPEG formats. Image manipulation can be done either through filters implemented in filter classes or by directly accessing the bitmap bits. Full C++ source is provided."
Good luck.

How can i switch my second view with another (in a spliter view).

You can use the SplitterEx class included instead of the standard one, and in your FrameWnd just use
m_wndSplitter.ReplaceView(0, 1, RUNTIME_CLASS(CNewView)).

The CSplitterEx class was included in my first reply, in an attachment you should be able to get from the forum. Regards, Pascal

Hi,
I have a subclass of CRichEditCtrl, and for some reason it does not receive the WM_LBUTTONUP message. I've verified this with Spy++, as well as the following code:
void CCommandLineEdit::OnLButtonDown(UINT nFlags, CPoint point)
{
TRACE("OnLButtonDown()\n");
CRichEditCtrl::OnLButtonDown(nFlags, point);
}
void CCommandLineEdit::OnLButtonUp(UINT nFlags, CPoint point)
{
TRACE("OnLButtonUp()\n");
CRichEditCtrl::OnLButtonUp(nFlags, point);
}
Commenting out CRichEditCtrl::OnLButtonDown(...) does allow the OnLButtonUp function to be called, but this also prevents the user from moving the caret by clicking the mouse anywhere (as well as making any type of selection with the mouse).
I do have ENM_MOUSEEVENTS specified in my SetEventMask() call. Also, the problem isn't unique to this individual control.
Has anybody seen this problem before or know of a way around it? (Preferably other than setting a timer on lbuttondown and polling for the button to be released).
Thanks for any help!
Jeremy
