Hi
In my application I want to start the application by dragging an associated data file and dropping onto the application or by file association. I retrieve the file name from the m_lpCmdLine variable which contains the file name with the complete path. I set a CString variable "strCWD" to equal the m_lpCmdLine but the File.Open command bombs to my error capture routine for "Nonexistant file". However, when I manually set strCWD to the same path and file contained in m_lpCmdLine, it opens correctly with the drag/drop routine. Does anyone know what is up with this?
Getting desperate...
code snippit (Sidebar: Can someone instruct me as to how to keep the code snippit format, i.e., tabs and spacings? Mine seem to be totally removed no matter how I format it.
// The main window has been initialized, so show and update it.
int nCmdShow = m_nCmdShow;
((CMainFrame*)m_pMainWnd)->InitialShowWindow(nCmdShow);
// Parse command line for standard shell commands, DDE, file open
// CCommandLineInfo cmdInfo;
// ParseCommandLine(cmdInfo);
// Dispatch commands specified on the command line
// if (!ProcessShellCommand(cmdInfo))
// return FALSE;
CFile File;
if (m_lpCmdLine[0] != '\0')
{
// drag & drop file to open
OnFileNew();

Does this causing the creation of invalid path ? I mean to say does g_strProgramPath is ended with "\\" , as your code is appending file name in front of that.

You're looking at the standard open with application opening file. Back up to the drag and drop opening. The section labled as...
// FILE ASSOCIATION OR DRAG & DROP OPEN APPLICATION STARTUP
is the code section that executes on file association or drag & drop. I compile using the m_lpCmdLine setting the path, the program displays the proper path, but refuses to open, i.e., possible invalid path. However, using the // MANUAL STRING setting strCWD to the exact path, program works! Go figure. Does m_lpCmdLine require using the ParseCommandLine(cmdinfo) to extract the file path properly? Why doesn't the string contained in m_lpCmdLine represent a valid file path usable by the CFile File.Open(strCWD) command?
Thanks for responding!

What does the control "list control" do? Could somebody make an example that explain how to use it?

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.

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.
