i am using windows

yeah i changed it to sizeof(wchar_t) or strlen(L"ซ").i think it fixes the bug but doesn't fix my problem, so do you have any idea of how can i write ซ in my text file?

i read all the links you gave me above, it was useful but didn't helped me fix my problem, as you said my character is two bytes and wchar_t can store two bytes too, then no problem with the way i input it right? and as i said above, this is how i read the data Read_From.open(Read_File_Name, ios::binary | ios::in); Read_From.read(buf, sizeof(wchar_t)); but no luck there, i really don't know what am i doing wrong, and what to do. but there is one thing that if i use one of ascii characters it works just perfect.

o.k i just changed 1 to sizeof(wchar_t), now it is inputing one more character than the buffer data itself contains, before i mean with write_on.write(buf, 1); it was converting my custom character to (VT) but the way you said as sizeof(wchar_t) it is adding (SO) over just for nothing, and this is the way i read data
Read_From.open(Read_File_Name, ios::binary | ios::in); Read_From.read(buf, sizeof(buf)); i also have tried Read_From.read(buf, 1);

well if you think it has something to do with text editor, this time i wrote the character and read it through my code no text editor needed, but still no difference, and thanks for your reply

hey what is going on, I can't find either of my comment and solutions.

hey where did all of my comments go?

I really really am sorry. but I unfortunately can't understand you mean by use the new nPos value to move the button. could you show me how to use nPos and how to change its position.

alright look, the thing is that I don't how to find out if the user has scrolled down 1000 line, if I try add this if(si.nPos > 1000) si.nMax = 2000; after if(pos == -1) would it work

anybody help me out with this.

okay that didn't worked, there is one more thing I think I can do, what if I tell the scroll bar that if the user scrolled like 1000 lines extend the si.nMax value. well i can't do it without your help cause i don't know how to do that, so i would really appreciate if you tell how to do that.

alright do you mean, instead of scrolling the window itself tell the scrollbar not to scroll the window but to set a new position to the buttons, am i right?

you said that I could paint pixels instead of moving it, but unfortunately I don't know how its done. I would be really thankful if you tell me how to do that.

anyone can help me?

can't believe i am saying this. but i need an new solution. i mean the above answer worked perfect but i thought instead of using mdiclient it would be good to use our self drawn window with its own class style. but in this one i can't add ws_vscroll or ws_hscroll, i mean i can but when i try to scroll down or something it just jump back to the top. so i would appreciate is somebody tell me how can i achieve creating the scroll bars to a self drawn window.
Here is the code how i create the window and class

Code:
wcs.cbSize = sizeof(wcs);
wcs.lpszClassName = szClassName;
wcs.hInstance = GetModuleHandle(0);
wcs.lpfnWndProc = CustWndProc;
wcs.hCursor = LoadCursor(NULL, IDC_ARROW);
wcs.hIcon = 0;
wcs.lpszMenuName = 0;
wcs.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcs.style = 0;
wcs.cbClsExtra = 0;
wcs.cbWndExtra = 0;
wcs.hIconSm = 0;

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

hwndCtrl = CreateWindowEx(
0L, // give it a standard border
szClassName,
_T("A custom control"),
WS_VISIBLE|WS_CHILD|WS_VSCROLL|WS_BORDER,
0, 0, 0, 0,
hWnd,
NULL, GetModuleHandle(0), CustWndProc
);

thanks in advance

Thank you, fixed it, the problem was that i was trying to make it in hwndCtrl which i was suppose to put hwnd instead. and now it works perfect there is no problem of pumping messages. but anyway thank for you help

i read all the documents you said and i did the way they are doing, could please tell me a particular point where i should pump message at.

thanks sir, i think you are talking about wm_create to return something. i did added return 0; before break for wm_create which i think you know what that mean better than but still no result.

least i made it working, and there is another problem, WM_CREATE does not works i mean the rest works fine like wm_paint and others work fine , but WM_CREATE doesn't here is my code:

LRESULT CALLBACK CustWndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_CREATE:
HWND Button1; // The name of the button will be Button1
Button1 = CreateWindowEx(WS_EX_CLIENTEDGE, "BUTTON", "Text on button", WS_CHILD | WS_VISIBLE, 0, 0, 30, 30,hwndCtrl, (HMENU)3, GetModuleHandle(0), 0);
break;
case WM_PAINT:
HDC hdc;
PAINTSTRUCT ps;

hdc = BeginPaint(hwndCtrl, &ps);
EndPaint(hwndCtrl, &ps);
default:
break;
}

return DefWindowProc(hwnd, msg, wParam, lParam);
}

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
hInst = hInstance; // Store instance handle in our global variable

hWnd = CreateWindow(szWindowClass, "FindMe", WS_OVERLAPPEDWINDOW/*WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU*/,
CW_USEDEFAULT, 0, 1014, 585, NULL, NULL, hInstance, NULL);

if (!hWnd)
{
return FALSE;
}

WNDCLASSEX wcs;

wcs.cbSize = sizeof(wcs);
wcs.lpszClassName = szClassName;
wcs.hInstance = GetModuleHandle(0);
wcs.lpfnWndProc = CustWndProc;
wcs.hCursor = LoadCursor(NULL, IDC_ARROW);
wcs.hIcon = 0;
wcs.lpszMenuName = 0;
wcs.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcs.style = 0;
wcs.cbClsExtra = 0;
wcs.cbWndExtra = 0;
wcs.hIconSm = 0;

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

hwndCtrl = CreateWindowEx(
0L, // give it a standard border
szClassName,
_T("A custom control"),
WS_VISIBLE|WS_CHILD|WS_VSCROLL|WS_BORDER,
0, 0, 0, 0,
hWnd,
NULL, GetModuleHandle(0), NULL
);

ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);

return TRUE;
}

as you can see it is suppose to make me a button but it basically doesn't, the rest works fine i mean like if i try to create a rectangle using wm_paint it works okay.

any solution are really appreciated

well how am i going to store bitmaps in memory, if i create a bitmap in resources of my project would it store it in memory

hey can anybody answer me?

oh man the thing you recommended works perfect but now there is another problem, how do i change the picture when the mouse cursor is on the button. like when you bring your mouse pointer on a normal button the color changes a to a little blue, how am going to do that in my bitmap kind of button. and thank

yes, but do you see anything i am doing wrong in my code

first of all sorry for my late reply, next i read the whole article in that website above, but that does not work as it suppose to i mean if you call wm_create and add some line of code to create you a button or on wm_paint when you try to create a rectangle or something it just does not work but the compiler compiles it without any error or something. here is the code how i am doing this

Code:
LRESULT CALLBACK WndProcclient(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_LBUTTONDOWN:
{
char szFileName[MAX_PATH];
HINSTANCE hInstance = GetModuleHandle(NULL);

GetModuleFileName(hInstance, szFileName, MAX_PATH);
MessageBox(hwnd, szFileName, "This program is:", MB_OK | MB_ICONINFORMATION);
}
break;
case WM_CREATE:
HWND Button1; // The name of the button will be Button1
Button1 = CreateWindowEx(0, "BUTTON", "Text on button", WS_CHILD | WS_VISIBLE, 220, 0, 100, 20,hwnd, (HMENU)3, hInst, 0);
break;
case WM_PAINT:
HDC Chdc;
PAINTSTRUCT pa;
Chdc = BeginPaint(hwndClient, &pa);
if(!Rectangle(Chdc, 0,0,10,10))
MessageBox(NULL, "Error while creating rectangle", "Error", MB_OK);
EndPaint(hwndClient, &pa);
break;
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}

HWND ChildWindowCreation(HWND hWnd){
const char g_szClassName[] = "myWindowClass";
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;
HINSTANCE clientInst;

wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProcclient;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = clientInst;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+25);
wc.lpszMenuName = NULL;
wc.lpszClassName = g_szClassName;
wc.hIconSm = NULL;

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

hwndClient = CreateWindowEx(WS_EX_CLIENTEDGE, "MDICLIENT", NULL, WS_CHILD|WS_CLIPCHILDREN|WS_VISIBLE|WS_VSCROLL,
0, 0, 0, 0, hWnd, (HMENU) 1, clientInst,(PSTR)&clientcreate) ;

if(!hwndClient){
MessageBox(NULL, "Program did not made the stuff ready for you", "Error", MB_OK|MB_ICONERROR);
}

return hwndClient;
}
hope there is a solution for that,

the link is for controlling message not for creating handlers for windows controls,

hey bro there are laterally hundreds of link on each website you give me above so its kind of hard to find it, i mean i had my research there but no luck there, so i would be owner if you give me a specific link to help me with my problem and thanks for your help i appreciate it

those website are really useful, but unfortunately i have to say i didn't found what i wanted, and thanks for you reply

sorry could you redirect me to a tutorial where it could show me how its done?

anybody have any idea what to do?

Thanks for your answer it worked perfectly, one more thing if you could tell me, how do I change the MDIClient background color.

can anybody tell me what to do?

my dear brother guess you didn't understand me completely, let me explain it a little clearly, there is a textbox in my hWnd window, what i want it, is to when the user types something and pressed enter it should get the text and draw it in the window somewhere or something like that. and thanks for your help.

yeah you are right i didn't got any result means no text no where in window, and i can't do it the way you did, i mean you called UpdateGraph() function in wm_paint handler but i can't do that cause there are lots of other stuff in my function where drawtext is, i mean the function that calls DrawText()

i did the way you said above but still no result, isn't there any other better way to show a small piece of text in window

what's with the link

i don't understand what do you mean by application-level command protocol, could you please tell give me an example?, and is it possible to use to different port in an application

well i can create threads, but how the program is going to recognize that voice packet belong to voice thread and text packet belong to text thread. i mean let's say the client sent a text packet to server so how the server is going to recognize that this is a text packet which need to go to text thread? one more thing it does not hang the program. it just does not recognize it.

thanks,i made to create a new thread

can you tell me how to do this

you mean calling accept() in the main function, right

i didn't understand you, what do you mean.

how am i suppose to do that, i mean this is how it's made:-
private: Microsoft::VisualBasic::PowerPacks::DataRepeater^ dataRepeater1;

and
this->dataRepeater1->ItemTemplate->BackColor = System::Drawing::SystemColors::ControlDarkDark;
this->dataRepeater1->ItemTemplate->Size = System::Drawing::Size(232, 72);
this->dataRepeater1->Location = System::Drawing::Point(12, 158);
this->dataRepeater1->Name = L"dataRepeater1";
this->dataRepeater1->Size = System::Drawing::Size(240, 150);
this->dataRepeater1->TabIndex = 2;
this->dataRepeater1->Text = L"dataRepeater1";
this->dataRepeater1->CurrentItemIndexChanged += gcnew System::EventHandler(this, &Form1::dataRepeater1_CurrentItemIndexChanged);

sorry but i didn't understand you. what do you mean translate VB-Code to vc++.
