Unfortunately the standard push button and the combobox buttons are different. In the standard blue theme the push button is white while the combo box button is blue.
How does one draw custom controls using themes? Surely there must be an API provided for it if the custom control varies in appearance from the windows standard controls. Pre fisher-price was so much easier
You may be right

so, i've looked in a lot of questions about serial ports, how to establish one and so on... but my question is a little bit more accurate and I can't find an answer:
how do I access a single Pin for my serial port?
I established the connection via createfile and wanted to write to the 4th pin...
that's what I guess. I need to set an integer there...
actually I needed to rewrite the function:
outportb(portAddr, int n)
where n is an int... and portadr is given as adr(Com2)+4, so I guess that's the pin.
when I use writefile as:
(int 3 or 4 should be written)
WriteFile(porthandle, &"3", sizeof(txData), &bytesSent, NULL);
which is obviously wrong  I don't get the right result...
how do i have to use it???

So you want to send data out on a handshake (DTR) line as opposed to the actual TX pin? Maybe changing the cable is a better solution.

cannot change the cable cause its an old-school shutter-glasses device

Maybe using with EscapeCommFunction()to manipulate (bit bang) using the DTR line, but timing would probably not be accurate enough for anything but a very low baud rate, and everything would have to be handled by your app. (the UART would be just a glamorous voltage converter).

well I tried "EscapeCommFunction" with DWORD running in loop from 0 1500 as int
<br />
for (int i = 0; i<1500; i++)<br />
{<br />
DWORD set = (DWORD)i;<br />
EscapeCommFunction(porthandler, set);<br />
}<br />
but somehow it didn't work...
I guess it's rediculous to try the other 5000 values.

The second parameter of the EscapeCommFunction() is one of 2 values in your case. These will make the DTR line high or low.
1. CLRDTR Clears the DTR (data-terminal-ready) signal
2. SETDTR Sends the DTR (data-terminal-ready) signal

Depends on what you want to do with it and what type of connector you have.
zqueezy wrote: I established the connection via createfile and wanted to write to the 4th pin...
Well, if this is a DB25 connector then pin 4 is the RTS signal and if it's a DB9 connector it would be the DTR signal.
As jeron1 said you can use the ::EscapeCommFunction() to set or clear those signals.
You can also use ::SetCommState() to set up handshaking behaviour.
From user mode it's not possible to send data that is dependant on a specific baudrate on such pins since you cannot rely on the timing due to windows not being a real-time OS.
How are you planning to use the pin?

hi all,
if i declare variable like this in visual studio 6.0
i am getting error.
can anyone help me regarding this ??
regards
venu
|
|
|
|
|
like this? exacly like this?
const double ERROR=-1e30;
??
:] Try
const double ERR=-1e30;
it should work :]
ERROR is a defined name in wingdi.h and is equal to 0, so u can not use it again in your declaration in that way
|
|
|
|
|
as i'm not mind reader; but you could have guessed yourself that one would ask you to proovide the exact error description...
also, please explain where you do declare this variable
|
|
|
|
|
if he declared it in the right place probably the error message looks like that: "Declaration terminated incorrectly" 
Because the name: ERROR is already in use in wingdi.h
|
|
|
|
|
or "you have made an error somewhere. Fix it" 
|
|
|
|
|
are you certain ERROR is not already defined in some Windows header file ?
on my system, it's defined in WinGDI.h.
just change the name of your variable.
|
|
|
|
|
...or change the case to ErRoR 
Great job, team. Head back to base for debriefing and cocktails.
|
|
|
|
|
When I saw your suggestion ErRoR I forgot how Can I write error 
|
|
|
|
|
Not only is it hard for me to type, it's hard for me to LOOK at!
Great job, team. Head back to base for debriefing and cocktails.

|

I dare to say it looks like a Counter-Strike maniac's nick :]
It's a pity you didn't write 3rRoR :]

search the web for steganography
there an excelent series of articles here on CP, but it's in C#, if you don't mind

thanks .i search it on cp also.

I am developing a program right now. The program will most likely start as when windows boots and will manually be closed. I would like to ensure that once the program has started it will only runs in RAM until it is manually close. Is there any way to ensure and force programs?

do you usually run programs elsewhere ?
