With the help of Task manager. The application memory increases and decreases when we add and delete columns respectively.

Not a good choice. TM does not tell you how much memory your program is using, but the amount of address space that is in use, which differs from the amount of that address space your program is actually using.

So please suggest me some good tool which can tell me exact memory used by my application.

In all sincerity, why do you think you need to know this?

My japanese client is using Task Manager to see the memory. So i need to convince him that it is not a memory leak.
Japanese clients are very hard to convince.

Hello,
I wanted to create an application in which I wanted to start my application at specific time, say I wanted to start my application at every 3 PM. If my computer is not on at 3 PM, I must be able to start it on later time as well.
I using VC++/MFC application.
Happy Programming.

It would be simpler to use the Windows Task Scheduler.

I have tried to use various examples finding Windows Scheduler with VC++. But almost every application give one or other COM exception. Can I have a link or example which shows use of windows scheduler with VC++/MFC.
Here are some links I have tried,
http://msdn.microsoft.com/en-us/library/aa381915(v=vs.85).aspx[^]
http://msdn.microsoft.com/en-us/library/aa446855(v=vs.85).aspx[^]
In second example I am getting exception in
ITask *pITask;
LPCWSTR lpcwszTaskName;
lpcwszTaskName = L"Test App";
hr = pITS->Activate(lpcwszTaskName,
IID_ITask,
(IUnknown**) &pITask);
pITS->Release();
if (FAILED(hr))
{
wprintf(L"Failed calling ITaskScheduler::Activate; error = 0x%x\n",hr);
CoUninitialize();
return 1;
}

I meant use Task Scheduler instead of writing a program.

That would be the best choice if I am making application for myself. I wanted to create Application.

Reason : Please read the first line of example.
"This example attempts to run an existing task. This example assumes that the task and the test task already exist on the local computer."

Hi Shilpi,
Actually I used Notepad.exe as well, but got exception. Then I tried chrome.exe, though Chrome Browser running on my system. But doesn't work.

Did you manually add the Scheduled task of notepad and chrome ??
Go to control panel -> Scheduled task -> Add Scheduled task and than check for this task using your code.

Ok, i just cannot get it. How can i nitialize static class members? I got such situation:
class myClass
{
private:
static myClass *pThis;
public:
.................
};
Now i am trying to initialize pThis to "this" so i can use it in some static methods, like threads and so.
If i am trying to initialize it in constructor, compiler says that pThis is unresolved. Ok then, i am trying to initialize it to NULL outside a class, like this:
myClass *myClass::pThis = NULL;
Now linker says that pThis is already defined in myClass.obj. What am i doing wrong?
Thanks

In C# one would use a "static constructor", which runs once, when the class gets referenced for the first time. However there is no such thing in C++, the best you can do is probably what is explained here[^].

Yeah, that issue appeared because i have this initializer in .h file, not in .cpp

My previous message was incorrect; this works:
In your header file you have the class definition so:
class myClass
{
private:
static myClass* pThis;
public:
myClass();
};
in your implementation (.cpp) file you have:
myClass* myClass::pThis;
myClass::myClass()
{
pThis = this;
}

Yep, that is what i needed

..on the other hand, if you want to use it in thread functions it would be better to send it as a parameter to the thread function.
|
|
|
|

That is correct. Just wanted to avoid a lot of params and have one static instance for use everywhere

Then my guess was right, your construct is indeed meant as a way to implement a singleton.
This is wrong on so many accounts:
1. If you deal with multiple threads, this won't be thread safe
2. By making all your functions static, you give the false impression that these functions will not modify the internal state of your program, while in truth several effectively global parameters are being modified. Anyone else seeing and trying to use these functions may quite easily introduce fatal errors into the system.
3. Since your constructor creates the instance that you need, if that constructor is being called multiple times, your pointer will be overwritten, and you lose the current state of your application irrevokably.
4. Replacing function parameters with global variables is bad design. It will lead to functions producing different results with same parameters, making them effectively untestable.

Stefan63, that is just wrong. Trust me i know what i am doing. One question: how would you implement custom control class by making it singleton while you need , lets say 10 instances of that class? you got 10 buttons on your dialog - now make this singleton. Second, have you ever heard of "static trampoline" ? Try this: encapsulate WndProc, CreateThread and SetWindowHookEx in a class - you will get idea. In case of mfc, encapsulating wndproc is actually out of the question, but that is not the point. Cheers
