How to use the RTC Client API?I downloaded the version 1.2 and 1.3 and installed them,but I still

can't run the programmes about RTC on my Windows 2000 SP4 operating systems!!

Always "Initialization Error" !?

Run-Time Requirements:

The RTC Client API version 1.2 requires Rtcdll.dll on Windows Server 2003, Windows XP, and Windows 2000 operating systems.

The RTC Client API version 1.3 requires Rtcdll.dll on Windows Server 2003, Windows XP, and Windows 2000 SP4 operating systems.

Is there a way to check if a thread is currently suspended?

This is abit of a guess, but you could call SuspendThread, followed by a call to ResumeThread (these functions maintain a "suspension count", and test the return code of ResumeThread to see if it was suspended before your two calls.

to track the urls of ie, it is possible to create a "browser helper object" (a kind of plugin for (internet) explorer). if i remember well, you can be notified on each new navigation.

I just finished a simple program, but it keeps saying that I have a error. The error says that "end of program is found before left brace" line 37. What does that mean, here's my code:

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

int main()
{
//declare variables
double sales = 0.0;
double totRegSales = 0.0;
int region;
int outlet;

while (region <= 5)
{
cout << "region" << region << endl;
outlet = 1;
totRegSales = 0.0;
do
{
cout << "Enter sales for outlet" << outlet << "enter 0 for next region):";
cin >> sales;
totRegSales += sales;
outlet++;
}
while (sales != 0.0);
cout << "region " << region << "sales total:" << totRegSales << endl << endl;
region++;
}
cout << "End of program" << endl;

at the end of the program. all C/C++/C# functions (including main()) must end with a }

you have three { and only two }

at the end of the program.

all functions MUST end with a }. the code you posted above does not end with a }.

put a } at the end of the code, after your last "cout << .."

Weird double/int truncation error

I am working on a visual c++ project which has been getting lots of C4244 warnings (conversion from 'double' to 'int', possible loss of data), but has been working ok (as expected).
I made an effort to eliminate the warnings at first by using a preprocessor definition for round(x) (assuming that rounding was the intended operation in the first place) and then trunc(x) (#define trunc(x) (int)(x))), after finding out that rounding was not the intented operation after all.
Now, reading the related help files, I was under the assumption that the default compiler behavior when assigning a double to an int, is to truncate the double and assign only the integer part, thus, my trunc(x) preprocessor definition should work just the same.
Apparently, it doesn't.
Apparently, casting a double to int to get rid of the warning, does not truncate the double, or I am missing something here... Confused | :confused:

Does anyone have a clue about what's going on here? Confused | :confused:

Thanks in advance. Smile | :)

correct. casting double to int makes a copy of the double, truncates it, and assigns that to an int.

if you want to truncate a double in-place, you can do something like:

double foo;
foo = 1.234;
foo = (double)(int)foo;

I would use floor(), as it might be less confusing than casting twice.

Sorry, I'm afraid I have not made myself quite clear about the problem.
I do not want to truncate the double and assign it back to a double.
I have a program with lots of warnings about double to int assignments, and I want to gracefully get rid of these warnings, without modifying the default program behavior. As I have explained, my efforts so far (with casting and using round(x)) have been fruitless.

What about something like:

int i;<br />
<br />

<br />
i = static_cast<int>(d);

Hi,

I have a derived CFormView called CMyView. In this class there are DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE Macros.

In my CMainFrame i have a Message Handler to catch a menu click.

void CMainFrame::OnFileMyview()
{
if ( m_pClass != NULL)
{
m_pClass = RUNTIME_CLASS(CMyView);
m_pMyView = (CMyView*)m_pClass->CreateObject("CMyView");
}
}

How do i get my CMyView to display in my window.

Thanks
Gary

Just to see where I was placed , i took the test and scored a dismal 2.71 . The bar set by my employer is 4.0 . I would like to get information on preparation material for the test .

Thanks

I took that same test and scored about the same as you. I apparently don't know what I am doing, or the test is not a good indicator of what I do know. Big Grin | :-D
