can somebody tell me how to get object or resource id of all the controls by passing dilaog handle progrmatically.

You can use EnumChildWindows, calling, inside your callback function, GetDlgCtrlID.

What about simple call to GetNextDlgTabItem!

Does not work unless the control has the WS_TABSTOP set (I know, usually a control HAS this style set).

Hello everyone
I want to learn how can I do this :
write a recursive function member level() for class template BST that determines the level in the BST at which a specified item is located .The root of the BST is at level 0 , its children are at level 1 , and so on
and this is the code for //--- Definition of search()
Code:
template <typename DataType>
bool BST<DataType>::search(const DataType & item) const
{
BST<DataType>::BinNodePointer locptr = myRoot;
bool found = false;
for (;;)
{
if (found || locptr == 0) break;
if (item < locptr->data) // descend left
locptr = locptr->left;
else if (locptr->data < item) // descend right
locptr = locptr->right;
else // item found
found = true;
}
return found;
}

Hi all,
I am using CToolTipCtrl as follows:
m_ToolTip.AddTool(this,sToolTip,rc,1);
m_ToolTip.SetMaxTipWidth(MAX_PATH);
m_ToolTip.Activate(TRUE);
m_ToolTip.SetWindowPos(&wndTopMost,0,0,0,0,SWP_NOACTIVATE|SWP_NOSIZE|SWP_NOMOVE|SWP_NOOWNERZORDER);
MSG msg;
msg.hwnd = m_hWnd;
msg.message = WM_MOUSEMOVE;
msg.wParam = 0;
msg.lParam = MAKELONG(point.x , point.y);
msg.time = 0;
msg.pt.x = point.x;
msg.pt.y = point.y;
m_ToolTip.RelayEvent(&msg);
the tool tip is shown 100% ok, but when i log on to this site:
http://news.sky.com/skynews/home[^]
the tool tip stops from working. i think there is a control on that site that does something to my tool tip.
what am i doing wrong?
thanks in advanced

How can I change font of dialog box programatically at runtime.
I tested OnSetFont() member function and SetFont method but failed.
Thanks

IMHO you have to propagate the WM_SETFONT message to dialog controls (that are dialog child windows). For instance, you can call (inside OnInitDialog)
EnumChildWindows(this->m_hWnd, MyFunc, (WPARAM)(HFONT)(*m_pFont));
where MyFunc is something like this:
BOOL CALLBACK MyFunc( HWND hwnd, LPARAM lParam )
{
HFONT hFont = (HFONT) lParam;
SendMessage(hwnd, WM_SETFONT, (WPARAM)hFont , MAKELPARAM(TRUE, 0) );
return TRUE;
}
and m_pFont is a pointer to a CFont object.
hope that helps.

Thank you very much.
But it does not change size of the dialog!
I want that changes after setting a bigger font for example.

I have a propertyPage in which I have CEdits. I want to display text entred in thoses CEdits from another CDialog.
for example in my Page I enter in the CEdit m_edit1 the CString "myName" I want that I transmit this value to an CEdit of a CDialog m_CEdit.setWindowText(m_edit1)
so they recommanded me to add message handlers to controls of this page.
what does it means ? and how I use these message in this CDialog in which I want to receive the data from this propertyPage ?
thank's

for example:
<br />
<br />
COleDateTime my_Time;<br />
<br />
int i = 600;
<br />
If use this method:
<br />
my_Time.Format(0000, 00, 00, 0, 10, 0);<br />
that ok, but if i = 12345, or 54321, the convert should very difficulty.
I hope obtain a easy method.
Thanks!

Look at the equal operators; they take __time64_t. Convert your value to __time64_t and then assign it. (Look of _time64 for how to use this.)

if i always will be Time in Minute then what about passing this :-
CTimeSpan timeSpan(1000); //time in second
j=timeSpan.GetHours();
k=timeSpan.GetMinutes();
l=timeSpan.GetSeconds();
COleDateTime oleDatetime;
COleDateTimeSpan spanTwo;
spanTwo.SetDateTimeSpan(timeSpan.GetDays(),//int nDay,
timeSpan.GetHours(),
timeSpan.GetMinutes(),
timeSpan.GetSeconds()) ;
oleDatetime.m_dt= spanTwo.m_span;
a = oleDatetime.GetHour();
b = oleDatetime.GetMinute();
c = oleDatetime.GetSecond();

Hello everybody,
I am a newbie to C++ programming and I need to do some hex addition with VC++ and then output the result as ASCII.
Here is my problem:
hex1(5A 30 35 30 30) which is equal to decimal(387355848752), I want to add hex(100) to hex1, result is hex2(5A 30 35 31 30) equal to decimal(387355849008). This is exactly equal to adding 256 to the first decimal.
I know unsigned int data type can only support 4294967295 which is still not enough for my case, and I would like to know how to convert these hex to ASCII with VC++? (Help received! Thx)
Besides, I need to convert the output to ASCII string format, which is "Z0500" and "Z0510" respectively, how can I do that?
Your help is very much appreciated, thank you!
Here is the code with help from forum member, but my second question is not yet solve:
#include <iostream>
#include <atlstr.h>
#include <string.h>
#include <sstream>
#include <conio.h>
#include <ctype.h>
int main()
{
long long h;
long long h1 = 0x5A30353030LL;
long long h2 = 0x5A303F3F30LL;
long long h3 = 0x100LL;
CString Str;
unsigned char Write_Buff[1];
for (h=h1; h<=h2; h+=h3)
{
_tprintf_s(_T("%I64X\n"), h);
Write_Buff[0] = h;
Str.Format("0x0%x",Write_Buff[0]);
Sleep(10);
}
_getch();
}

What does "ASCII String Format" mean? I have found ASCII String Format and ASCIIZ searching on the web, and both refer to a simple C String. Here is an example that does that:
// Configuration Property: Character Set should not be set to
// Unicode, where _TCHAR = char
// Or, you can undefine _UNICODE and UNICODE
#include <stdio.h>
#include <tchar.h>
#include "stdafx.h"
#include <vector>
int _tmain(int argc, _TCHAR* argv[])
{
long long h1 = 0x5A30353030LL;
long long h2 = 0x100LL;
long long h3 = h1 + h2;
std::vector<_TCHAR> buffer(256);
int result =
_stprintf_s(&buffer[0], buffer.size(), _T("%I64X\n"), h3);
if (result == - 1)
_tprintf_s(_T("_stprintf_s faiiled.\n"));
else
_tprintf_s(_T("%s"), &buffer[0]);
return 0;
}
Also, is "Z0500" and "Z0510" some kind of command based on the above hex values?

Hi,
Thanks for the reply, here is what I finally wrote since 5A and 30 are kept constant.
unsigned long int z;
char buf[6];
z = 0x303530; // 5A-303530-30
do
{
buf[0] = 0x5A;
buf[1] = (z & 0xff0000) >> 16;
buf[2] = (z & 0xff00) >> 8;
buf[3] = (z & 0xff);
buf[4] = 0x30;
buf[5] = 0x00;
printf("%s\n", buf);
serial.Write(buf);
z = z + 1;
if ((z & 0xff) > 0x3f)
{
z = (z + 0x100) & 0xffff00;
z = z + 0x30;
if ((z & 0xff00) > 0x3f00)
{
z = (z + 0x10000) & 0xff00ff;
z = z + 0x3000;
if ((z & 0xff0000) > 0x3f0000)
{
z = (z + 0x1000000) & 0x00ffff;
z = z + 0x300000;
}
}
}
Sleep(150);
}
while (z <= 0x353130); // 5A-353130-30
It's HEX addaition of 1 and output to RS232 by cserial, thanks anyway.;)

I'm trying to store around 3000 chars in CString object, by using += operator, and concatenating chars to the end of CString.
The problem: When it around 250 chars in length the concatenation stops to work.
My guess was it's some problem with reallocation (when the buffer gets resized), but I tried with custom class with string of fixed length, and concat stoped at the same point. Now I have no clue what could be the problem.

It has nothing to do with what you've thus far described. A CString object can hold 231 characters.
Show a code snippet of the problematic code.
