I maked a test application for my HF-Transceiver. To communicate between PC and the Evolationboard of the HF-Transceiver I use the COM Port. I can't use the normal functions for serial communication, because my own telegramm to the transceiver don't have any Start or Stopbits. So I use the functions _inp and _outp to communicate directly with the register from the COM Port at adress 3F8 (COM1). To send the Data I used for synchronization an external clock signal, which I conacted to the CTS Pin. Now, I tested my programm and not all telegramm were correctly send. I modificated my programm to send only 01 as data for testing. With an oscilloscop I meased the CLOCK and DATA pin. I saw the error, the 01 intervall wasn't correctyl send. The error look like this.
CLOCK 01010101010101010101010101
0DATA 00110011001100001100110011
ERROR ( 4 * 0 is not correct)
It's funny, the CLOCK have 4600 baud normally. If i increase the baud rate to 19200 baud, no more error will be found. I don't know, if the problem is windows, because my thread can be stopped by windows, for short time. Or the problem come's from my code. This is my code for my send thread. I hope anyone have an IDEA or anyone can say an Internet adress to this theme THANKS!!!

First of all you should post your code by using < pre > and < /pre > tags.
My first comment would be about the start and stop bits. I think that no matter what, the UART inside the computer will send start and stop bits. I could be wrong because the last time I dealt with UARTs was 3 years ago, so check the books.
Sending clock signals is achieved by XOR-ing the last bit sent with 1 and then sending the new bit. It is faster and requires less hardware (in case you decide to put in hardware).
// Pseudo code
If clock.transition
BitToSend = LastBitSent XOR 1;
LastBitSent = BitToSend;
I think your problem is related to the start and stop bits, that you are ignoring. Check the frequency of the error (how many bits are correct before it happens?). What is CTS by the way because I don't seem to remember (Clear To Send? - if so why is your clock connected there?).
When you say an external clock, do you mean you have a crystal providing the clock signal, or are you sending it through the serial port? (your program looks like it is sending the clock signal through the serial port).

Sorry, I posted for the first time so much code. In my message i marked all code and click "code". Now the colour is brown. Is this not OK?
The Start & Stopbit will be send by the normal functions of "Visual C++". Only with the functions _inp and _outp I can only send my bits.The error didn't appear at all telegramm. Only in some telegramm.
Your are right, the CTS pin is normaly (CLEAR TO SEND). But I connected the extern created clock (from the transceiver or Waveform Generator) to this pin, becauce I can read this pin in the register with _inp.

No, no, it's okay, but it is always a good idea to use &lg pre > tags. Some comments would be great too because I don't understand statements such as this one:
else if(((_inp(m_ComBasisAdresse+6)|65519)==65519)&&lastBitOne) (there are more statements that I don't understand).
Still it is not very clear why the clock is connected with clear to send (doesn't the uart reset that signal on its own?). Every time the clock goes high, you send data out, right?
Did you check the error frequency?

Anyone has algorithm for drawing a line parallel to another line?

Is it that what you wanted?

Another solution if you have only the line equation: y = a*x+b.
Just change the offset value (b), the slope will be the same: y' = a*x' + c.
Hope this helps

How is your line specified at the moment? How you draw the next line will depend on that.

If you want to draw your line parallel to an existing line, you should store the points of that other line. You can use the suggestions provided by the others for drawing, they work perfect! 
good luck!

Thank you all for your support. I really need a routine which will work with polylines, handling the joints as well.
Best regards,
Paul.

I don't think that such a routine exists, but feel free to write it yourself
If it takes too long to get what you want, do it yourself

Right, I am working on it - just have to handle the joints well to complete it.

Hello,
1) how can I get the local domain name (normally something like WORKGROUP)? The method should work on both NT-systems and 9x.
2) how can I enumerate the network adapters? I've found only a method that uses Iphlpapi which I don't want to use.

I hope this is not the link that you are refering to [^]. You can also check GetAdaptersInfo but I am not sure how you can enumerate network adapters.

I am not sure about this question but I hope GetComputerNameEx function can be of use.

Ehm... This is getting the MAC addresses for the adapters. But what I am looking for is an enumeration function for "Client for Microsoft Networks", "32-bit fast ethernet adapter", "Microsoft Virtual private networking adapter" and those...
GetAdaptersInfo is the function I don't want to use... It's a Iphlpapi function...

Theoretically GetComputerNameEx is the function I am looking for, but this function is supported only by Windows XP and Windows 2000 Professional. But I need it for 9x systems too

Other than GetComputerNameEx, there are no other functions (to my knowledge) that can get the domain name. GetComputerName gets the NetBios name and it works on all versions of windows. I know you're looking for the domain name, but would that function work for you?

This is exactly what I didn't want to use. GetAdaptersInfo is a function of Iphlpapi...

NetWkstaUserGetInfo() will give you the information, but will only work with WinNT/2k/XP. Win9x systems have the same function, but it is a 16-bit function callable by 16-bit code only, exported from netapi.dll. You can only do it using 16-bit code, and using thunking to interoperate with 32-bit code. Yes, it's complex, and No, I don't know exactly how to do it, but's it's possible
This[^] article gives the information. The first call to NetWkstaGetInfo() will provide you with the domain name - look up the docs for NetWkstaGetInfo() to work out how to extract the information.
Hope this helps,

I know you can do #2, and I am guessing #1, using WBEM and WMI. WBEM is only included with Windows 2000 and XP, but I believe it can be installed on previous versions.
I'm a complete and utter newb when it comes to WMI/WBEM, but do some searches on them to see if it can do what you want. I think it's your best bet. I've done #2, but only on XP and using somebody else's wrapper class.

Hi
I want to write to screen: 'RéSUMé' . The characters 'é' in capital.
I made a CString strText("résumé");
strText.MakeUpper();
It makes all characters to upper expect for the 'é' ones.
I've looked up the character ascii code for 'é captital' and that is 201.
How can i put this character in the text?
Greetings
Jens

Why not hard-coding it when it isn't a dynamic string?
CString strText("RÉSUMÉ");

#include "../disclaimers/standard/technical_ignorance.h"
I have a (mostly) peer-to-peer application that uses windows sockets to communicate with a server and also has it's own web server to serve up information to other peers.
This all works perfectly until users put themselves behind a firewall/router/etc.
As far as I understand (see disclaimer above), a user can use a SOCKS 4/5 proxy server to gain access to the outside world for this kind of application, but the P2P application needs to be SOCKS compliant.
- Is this true?If so, what do I need to do to make my application SOCKS compliant?
- Do I need to make any changes to the server application?
Your help, assistance and guidance would be gratefully received.
