Hi,
I am currently working on a project that will require me to set one of the stop bit. My com setting will be set to 2 stop bits. But I would like to set one of the stop bit to '1' or '0'.
How can I go about doing this?
|
|
|
|

You can't. The hardware is not capable of doing this. The purpose of the start and stop bits is to allow the receiving hardware to synchronise with the transmitter.
I suggest you read this Serial and UART tutorial[^].

hi there
well i have come across many Sharewares, that allow admins to shutdown their clients
HOW DO THEY DO THAT? perhaps its some knowledge related to admin previliges that i dont know..... and is it that they use RPC or what ........
please someone throw light on this.
thanx
|
|
|
|
|
|
no actually I was not looking for the API, I was rather interested in the previleges and networking involved.
U see, these sharewares dont require any kind of installation or configuration on the clients.

Hello!
I am translating dialogs by calling EnumChildWindows in the dialog class. Windows then calls my translation callback function for all child windows, which looks like this:
BOOL CALLBACK TranslateWindowCallback(HWND hwnd, LPARAM lParam)
{
TCHAR sz[1024];
GetWindowText(hwnd, sz, 1023);
SetWindowText(hwnd, TRANSLATE_FN(sz));
return TRUE;
}
This works pretty fine, but unfortunately it also translates edit controls and rich edit controls. I don't want this. It should translate only buttons, checkboxes, radioboxes, static texts, ...
How can I get the type of a window using only the HWND?
Thanks and best regards
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Check for GetWindowInfo(...) api as one of its argument return with class information of window i.e. WINDOWINFO::atomWindowType, which on using with GetClassInfo(...) api, you will come to know class name of window and As BUTTON, CHECKBOX has predefined classes, So I believe it very easy for you to differentiate it with rest of windows.

My VC++ 6.0 doesn't know WINDOWINFO and GetWindowInfo 
Any other method?

I've searched around a bit for window class names and found the function GetClassName. This function seems to get the class name directly (your function doesn't do anything other, or?). Any reason not to use this function?
Thanks for your replies and best regards

Not sure what you mean by this.

Easy enough:
CFile file(...);
for (int x = 0; x < 10; x++)
file.Write(&x, sizeof(int));
file.Close();or
CStdioFile file(...);
for (int x = 0; x < 10; x++)
{
CString str;
str.Format("%d\n", x);
file.WriteString(str);
}
file.Close();

Hi,
To show the printer Dialog, you can use CPrintDialog class with appropriate values in the constructor.
May be this will help u, if u use mfc.
Find the job u love and u never have to work for a day in ur life.

I am used to create objects in MFC by draging icons and connect to MessageMap by suing Class Wizard.
Now I want to create CButton object dynamically as when I type "20" in a Edit then click a button to create 20 buttons in my dialog.
But....how(where) do I put the point of these 20 buttons ?
And ..
If I've created these 20 buttons, how do I connect these buttons to Message Map ?
I have no idea about these question ...
Gave me a hand , please ....

Hi,
U can use the following method to create the buttons dynamically. In the following statement "but" is the CButton object which is declared as public class variable.
if(!but.Create("click me",WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,CRect(10,10,100,30),this,ID_MYBUTTON))
AfxMessageBox("Button Not Created");
else
AfxMessageBox("Button Created");
The argument ID_MYBUTTON is a macro and should be replaced with some integer values like below.
#define ID_MYBUTTON 100
Then the message handling mechanism. First declare the member function in the class like as below.
void MyMessage();
In the message map macro add the following step. This should be in the message map of the class in which u r going to create the button.
ON_BN_CLICKED(ID_MYBUTTON,MyMessage)
and define the function, i.e., MyMessage().
finally make sure that, ur member function and data members are displayed in the class view.
Hit the execution icon, and check the result.
Hope this will be little drilling for the people who doesn't have much knowledge about mfc and its message hook mechanism.
Let me know if u have more doubts.
thanks,
Zxczc

Hello ,Zxczc
Thank you for your reply
I think I forgot to express an important factor.
Before I input a number in the Edit and click the create Button ,the AP doesn't know how many Button it need to create.
I don't have a good sense, so that it is what I mean "dynamically".
Dose it possible to do?
Or I must to decide the maximum number of the button in source code, then hide the useless button?
Is that the only way ? or there is another better method?
Thank you

Sure it is possible!
But you are very much on your own here, without the Wizard and the MFC macros.
MFC may good enough for your little sister, but Win32 is for real men, you know?
Create the Buttons you need, and catch their BN_CLICKED notification.
That is done by overriding PreTranslateMessage and waiting for a WM_COMMAND message with a HIWORD(wParam) being BN_CLICKED.
The LOWORD(wParam) is the identifier (the last number of the CREATE-statement) and the lParam the buttons handle.
Now you have full control over the button.

I've been trying to do a simple program like the one on this site about toggling the proxy settings. The problem is when i try to compile I get this error.
Form1.obj : error LNK2001: unresolved external symbol "int __stdcall InternetQueryOptionA(void *,unsigned long,void *,unsigned long *)" (?InternetQueryOptionA@@$$J216YGHPAXK0PAK@Z)
I can't seem to crack where the problem is. I have this includes
#include <iostream>
#include <string>
using namespace std;
#define WIN32_LEAN_AND_MEAN 1
#include <windows.h>
#include <wininet.h>
#include <urlmon.h>
#include <stdio.h>
#include <winsock2.h>
#include <ws2tcpip.h>
#include "strsafe.h"
#include <stdlib.h>
#define INET_ERR_OUT_MSG_BOX_BUFFER_SIZE 512
#define INET_ERR_OUT_FORMAT_BUFFER_SIZE 256
#ifdef _UNICODE
#define _itot _itow
#else
#define _itot _itoa
#endif
#using <mscorlib.dll>
using namespace System;
using namespace System::Security::Permissions;
using namespace Microsoft::Win32;
AND THIS LITTLE CODE:
InternetQueryOption(NULL,INTERNET_OPTION_USER_AGENT,NULL,&dwSize);
char *lpszData;
lpszData = new char[dwSize];
InternetQueryOption(NULL, INTERNET_OPTION_USER_AGENT,lpszData,&dwSize);
delete [] lpszData;
at first it did not have the char *lpszData; because in the Microsoft page didn't have it and I got undeclare variable.
Any thoughts...
