Update: My previous message referred to CRectTracer which, of course, I regret to say was a TYPO!! Please ignore the previous message. Here comes the corrected version:
Could some-one discuss the subject topic in some detail; i.e.the use of CRectTracker, but withhout OLE. Please note I have already searched the internet.
I have successfully "barebone"-d (i.e. "analysed") MSDN's TRACKER example (also the Blocks32 example) but I need more material (description or tutorial) on how to use subject class members. All one can find in the MSDN class library is a minimal content.
TIA.

Hi! I'm new programming and I'm trying to test if a number is palindrome, example if I input 434 return true;... or 789 return false;... when I try to run my program I get this message " 'pow': ambiguous call to overloaded function"... Could anyone please tell me what causes these function to fail... this is my code:
#include <iostream>
#include <cmath>
using namespace std;
bool isNumPalindrome (int num);
int main()
{
return 0;
}
bool isNumPalindrome(int num)
{
int pwr = 0;
if (num < 10)
return true;
else
{
while(num/static_cast<int>(pow(10,pwr))>=10)
pwr++;
while (num >= 10)
{
int tenTopwr = static_cast<int>(pow(10, pwr));
if ((num / tenTopwr) != (num % 10))
return false;
else
{
num = num % tenTopwr;
num = num / 10;
pwr = pwr - 2;
}
}//end while
return true;
}//end else
}

The function is not failing. Rather, the compiler cannot figure out which (of the seven) pow() functions to call based on the type of arguments being passed to it.

Break this up into multiple statements so that you can figure out what is going on. Bunching it all up together does not buy you anything performance-wise.
Your function looks overly complicated. You could simplify it a bit by comparing the symmetrically opposite pairs of digits. For example, in the number 24677642, you would first compare the 2s, then the 4s, then the 6s, and finally the 7s.

i have a list control and have another seperate dialog to display file size when i press a button. i need to have a file selected before it displays its size.. any help?????? cheers im going round in circles and am new to this thing

why don't you disable the button if no item is selected in the listbox ?
use CWnd::EnableWindow(FALSE) for this

you need to validate the Button click .. some thing like this :-
CListCtrl* pListCtrl = (CListCtrl*) GetDlgItem(IDC_YOURLISTCONTROL);
ASSERT(pListCtrl != NULL);
POSITION pos = pList->GetFirstSelectedItemPosition();
if (pos == NULL)
// DONT DISPLAY DIalog
else
{
// DISPLAY DIalog
}

I have MDI application, that needs 3-5 different User interfaces to present and get information to the user. I pretty much only need the standard button, radio buttons, check boxes, and edit box to get and present this information.
Q: Which way is the best to create the individual UI's in MDI application. Right now, CFormView and/or a Dialog seem to provide the same capablities. What is the difference between these two objects in MDI app.
My final product, will have 3-5 User Interface that will each be used to configure a individual C++ class object. Each of these C++ objects will control a single part of large system that all works together. The large system will a consolidate all the individual class objects into a single class with finite state machine that will run in seprate thread.

I have a mem HDC which represents an 8 bit greyscale bitmap.
I want to draw the contents of another HDC which represents a 32bit color bitmap into the 8bit dc. When I use BitBlt for this I get weird shearing effects which I presume come from trying to draw the higher bit depth image into the smaller bit depth.
So my question is: what is the best way to do this?
I thought BitBlt would handle this for me, but I guess I was wrong.

I have question About VB6 Of Asc() Function
the "人" can convert into the -14133 in VB6.
so,how to do this In VC6
VB6 Code:
Private Sub Command1_Click()
MsgBox Asc("人")
End Sub
Show:-14133
thanks

If you're using the Unicode character set in your C code then the wchar_t values in strings
are the Unicode character codes for each character (0x4EBA for "人").
I think something like this would emulate your VB code in Unicode C (using the deprecated
wsprintf());
wchar_t test = '人';
wchar_t buffer[64] = L"";
::wsprintf(buffer, L"%hd", test);
::MessageBox(NULL, buffer, L"Caption", MB_OK);
-14133 (0xC8CB) is a GBxxx character code I believe. I'm not sure how you work with the GB
character encoding in C but this link may help:

I hope this helps a little.

Use WaitForSingleObject().

no it doesnt work. both exes are executing at a time
|
|
|
|
|
Then you've done something wrong. Hows are you calling ShellExecuteEx() and WaitForSingleObject()?
