What is the different between Synchronization and block?

I find that I could not distinguish the synchronization from the block, and asynchronism from no-block.

when use the synchronization to socket with the server, it must be block model. How to achieve it with the non-block model?

I don't understand your question. You probably mean synchronisation in the context of multi threading, with non-blocking sockets (asynchronous networking) you typically have a single threaded application.

Thanks for your reply. It not multi-thread, it is using socket. I do not know the different between synchronization and block.

Hi everyone ! Do anybody know ( because I took from here many useful links ) an auto complete control implementation of CEdit or CComboBx control ? I found HEREsomething interesting , but not working on SDI/MDI application , so is in vain , and autocomplete implementation is based on CList , not on CListCtrl ... any hint or link will be very appreciated ! Thanks in advance !

i am a newbie and creating a project in c language on windows platform.
i am trying to develop a small application using winAPI 32. I am taking online tutorial from winprog.org ,in my tutorial i am creating a window from a given code but when i run the code ,my window name appearsll to be in different language .The code i used is given below. I am not able to understand why this sia happening . please help me .. I am using vc++ express edition 2008 on window 7.

i'll be very thankful to you.

#include <windows.h>

const char g_szClassName[] = "myWindowClass";

// Step 4: the Window Procedure
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;

//Step 1: Registering the Window Class
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = NULL;
wc.lpszClassName = g_szClassName;
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);

if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}

// Step 2: Creating the Window
hwnd = CreateWindowEx(
WS_EX_CLIENTEDGE,
g_szClassName,
"The title of my window",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, 240, 120,
NULL, NULL, hInstance, NULL);

if(hwnd == NULL)
{
MessageBox(NULL, "Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}

ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);

// Step 3: The Message Loop
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}

Always use code block and paste ur code in betweenthat block. code block is right on the text field where you write your question. Number of people answering you question, will dramatically change. TRUST ME. Thumbs Up | :thumbsup:

See, that is a problem with editable posts: the enquirer did not format properly in Q&A, someone cleaned it up, and the enquirer probably didn't learn a thing; he may get an answer and never figure how to use PRE tags.

Unsure | :~

Listbox control not accessible in another class??

hello guys...I added ListBox control on the form, so it accessible in MyProjDlg.cpp only. Now I want to add something to this ListBox from some other class "MyClass.cpp". So I made a function setter() in MyProjDlg.h like this....

#pragma once
#include "afxwin.h"

class MyProjDlg: public CDialog{
   //construction
   public:
           .....
   //implementation
   protected:
           .....

   public:
	afx_msg void OnAdd();
	afx_msg void OnDelete();
	afx_msg void OnShow();
	void setter(LPSTR str);  //here is the function I manually added...
	CListBox ListVar;
};

and gave its its implementation in MyProjDlg.cpp

void setter(LPSTR str) {
        //to keep things simple, messagebox is hown here..
	MessageBox(NULL,str,"",NULL);
}

and used it in MyClass.cpp like this..

LPSTR str = "Rumble in the Bronx"
for (int i=0; i<5; i++) {
     setter(str);
}

problem is,setter()it is not accessible in the MyClass.cpp....why Confused | :confused:

setter() is a member of the MyProjDlg class so can only be called on an object of that class.

It's time for a new signature.

well i tried this

CMyProjDlg asd;
asd.setter();

and this

CMyProjDlg *asd;
asd->setter();

in both cases the intellisense is not showing the function, off course which means it is not available.

Did you think to #include "MyProjDlg.h" in your cpp file? Also note that in case 2 you have not initialised your pointer to actually point to an object; don't be fooled by it possibly working.

It's time for a new signature.

then solve that. Not including a necessary header never is the solution.
