My suggestion is to make it appear that the thread exits immediately even though it doesn't. In your MSN message example, how do you know the thread stops immediately? If a dialog box goes away, maybe it wasn't controlled by the blocked thread. After all, how does it respond to your click on "cancel sign in" if the thread is blocked?
Also, are you sure the MSN messenger thread is blocked? Maybe it made an asynchronous call and is processing messages until it gets a reply.
If you absolutely have to have the thread exit immediately, you can call TerminateThread, but read the docs about why it's a bad idea.

In addition to the obvious answers you'll get, I thought I'd add a little apparently-not-too-well-known-something.
Depending on what the thread is blocked by, what you request might actually not be possible. There are instances when a thread hangs in the kernel, making it effectively impossible to terminate the process (the only way to terminate such a process is power off or hardware reset).

Hi,
Anyone knows how to implement a class similar to RichEdit control (i.e. with text formattings) and the method we can get the mouse click on some words (or "links") in its content ?
Thanks

hi,
I got a dll file in which one of its function process time
is about 5 seconds.
When I do iteration, the process time becomes 5 seconds x
number of iterations which makes my application very slow.
I tried to create multiple threads in my application
but it didn't have effect because those thread will
share a single thread of the dll.
According to what I've read in MSDN, all windows application
share the same dll process in memory. So if many application
use it, its process becomes slow.
My question is, Is there a way to create multiple process
of the DLL in memory? So I can use different processes of
DLL for each iteration? any pointers or any article suggestions..please..thanks in advance

I have a small challenge I need some help with. I have a
CScrollView derived class that displays columns, and each column has a header associated with it. I want the headers to always be displayed even when the view is scrolled. Thanks in advance for your response.

|
|
A solution could be to use two views in the frame, one for the data and one for the column header.

Hi,
After reading article at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvc60/html/redistribvc6.asp ... I am very surprise that we have to do a lot of steps to distribute a single Visual C++ application working with MS Access & DAO
Is there any simple way to include every thing in a single CD? Here are what I have:
a) An Visual C++ 6.0 application: Trial.exe
b) A Trial.mdb that is needed for the Trial.exe (MS Access2000)
What I need more to put in the package and install them in a PC that has Window98 (or later) without having MS Access & Visual C++?
I do know one thing, if I install in that PC ---> Visual C++ only with Access Database option ... it will work! How can I do a similiar task without installing Visual C++?
Thanks for any help

Hi All,
I have a vexing problem related to CListCtrls within nested CPropertysheets.
Very standard stuff here, the invisible CListCtrl is on CPropertyPage along with several visible CButton controls.
DWORD dwStyle = LVS_REPORT | LVS_SHOWSELALWAYS | WS_CLIPCHILDREN |
WS_CHILD | WS_VISIBLE | WS_GROUP | WS_TABSTOP | LVS_EDITLABELS ;
DWORD dwEXStyle = LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | WS_EX_CLIENTEDGE;
It must be obvious but I cannot see it.
If there are any kind souls out there - please help
Regards In Advance
Bonnie

Do you have a group box on the property page as well? If you do, check the tab order as it can hide any controls under it. Try putting it before/after the control being hidden in the tab order.

How do i add multiple document/views to an MDI app??
Is there something else that has to be done other than add additional
document/view classes and AddDocTemplate statements to the InitInstance of the mainframe?

I recently just started to design a tool to help me at work, it works kind of like a Hotel Reservation system. Before we used a program called "Calendar Creator" to manage all the reservations for a given day; however there are a lot of other ways we need to view the data as well. For example sometimes we need to submit reports on how many people are staying in certain buildings and percentages. So I decided to write a tool to manage all this. Everything is going good so far, but one problem.. I need this tool to be able to write all the added entries to a calendar. So I figured I would create a "Calendar View" that would display a calendar with all the added entries. However I soon found that there are no standard or popular calendar controls. So far ever Calendar controls I have seen are really just date pickers. So I figured I would write one myself, however I'm bad at math.. so the question.
1. Do I have to write one myself? (I don't want to re-invent the wheel)
2. If I do have to write it myself, how would I be able to tell that say Feb 10 2003 would be on a Monday?
Any help would be appreciated.
Thank you.

I've worked with the Microsoft calendar controls and they seem to be full of lots of frustrating bugs, so I'd say you're probably better of working from scratch

Hi, is there a simple way to program complex equations in MFC AppWizard(exe)??? For the equation z = z^2 + c, where 'z' and 'c' is (r + i), I was able to program it like this:
//r2 and i2 the user gives the values for
//r and i are the 'x' and 'y' values on the complex plain
//r5 and i5 is the final 'z' value
r3 = (r2 * r2) + (-(i2 * i2));
i3 = (i2 * r2) + (i2 * r2);
r5 = r3 + r;
i5 = i3 + i;
r2 = r5;
i2 = i5;
I need the final answer in complex form (r + i) so I may be able to put those values back into the equation as 'r2' and 'i2'... I want a simpler way to do this so I can use bigger equations like:
z = ((z^5 + c)/(z^3 + z^2 + z + 1)) + sin(z)
Thanks...

Use the Standard C++ complex class.
#include <complex>
std::complex<double> z, c;
z = std::pow(z, 2) + c;
|
|
|
|
|
How would I get the 'r' and 'i' values from the 'z'???
|
|
|
|
|
How would I get the Real and Imaginary values from the 'z'???
|
|
|
|
|
double real, imag;
complex cplx;
T = complex(1.0, 2.0)
real = cplx.real();
imag = cplx.imag();
|
|
|
|
|
It gives me an error saying 'complex' is "undeclared identifier"...
What I need to do after I got 'z' is this:
Final = abs(pow(pow(z[REAL PART], 2) + pow(z[IMAGINARY PART], 2), 0.5));
'double Final' is a single value...
Thanks...
|
|
|
|
|
#include <complex>
using namespace std;
double final;
complex<double> z(1.0, 2.0);
final = abs(z);
pow(x, 0.5) is the same as sqrt(x).
abs(z) where z is a complex number calculates the same value as your formula.
