Programs like VTune help you find out where most of the time is being spent.
You can also roll your own timing functions to determine how long specific sections of your code is taking.

Thanks.
I believe The Code Project has a class, PerfTime, in its archive that does the job.

I'd be very happy if anyone could give me some sort of solution to the following problem:
I am making an .exe file that exports a few function.
The problem I ran into is that if I call malloc inside one of those functions it always returns NULL .
My guess is that no local heap has been initialized, as the C runtime initialization code get's confused by the fact that it's an exe (and therefor no dll entry-point function is called)
If anyone could tell me how to come around this (I need to be able to use the new operator, which calls malloc , which uses _crtheap , but the latter is not exported from the c runtime dll).
Enjoy!

No, this is not true.
Functions exported by exe files can be used in exactly the same way as those exported by regular dlls
Enjoy!

How are you doing to call the exported functions from another executable? Like a normal DLL, loading with LoadLibrary and obtaining the function poitners with GetProcAddress ?

So you're using CSystemTray but don't want the system tray icon? The simple answer is don't use CSystemTray, as that is what it is desgined to do. What exactly are you using it for?

I know close to nothing about Crystal Reports, but Crystal Decisions website has this article which seems to list the files needed for distribution of apps based on the technology. If this is not what you want there's likely to be more information in that website.

Hello there,
I just want to know how you create a new document based on an existing (i.e already open) Document in an MDI. ok, the real problem i am facing is: I am developing an Image processing software. Now when the user opens an image and says for example Image>Convert to Grey Scale, I dont want to touch the original document. I want to create a new document that is a clone of the existing image, and do the operation on that. Then it will be displayed as a separate MDI child Window. Please tell me how to do that

Given this:
try
{
MyClass->DoSomething();
}
catch (...)
{
cout << "Unknown exception";
}
I am trying to catch a null memory exception (where MyClass is NULL). Is there a specific way to catch this (catch (/*NULL MEMORY*/)), or am I conformed to using the catch all "..." method, or sticking with "if (MyClass!=NULL)"?
|

You can also have inside DoSomething a check for this == NULL.
But what you might be looking for is SEH (structured exception handling). VC++ actually has 2 exception systems, C++ and SEH (the exception system of the OS). Look for information on converting SEHs into C++ exceptions. That will get you a closer to what you are looking for.

Ok, here goes...I've got a dialog-based application. From this application I have created a modeless dialog box. When the user closes the modeless dialog box, I need to access a variable within my main Dlg box's class, in order to save data from the modeless dlg box. So, as I see it, I need a pointer to it. How do I get a pointer to the Dlg class of a dialog-based app??

Create the dialog with this as the parent (m_Modeless.Create(this);) and store the value, or call GetParent and cast the return to an instance of your dialog class.
I tend to create modeless dialogs in the constructor, by doing this:
if (Create IDD, pParent)) ShowWindow(SW_SHOW);
and store my modeless dialogs as pointers.
Then I can do this
m_Modeless = new CMyModeless(this); // Dialog is now created.

Christian - do you know if this would work with a Tabbed Dialog Box such as the one Derek Lakin presents 'CTabCtrlSSL' ?
I need to do something like this, but only add a new dialog one at a time, depending on if the user presses 'continue' or 'ok' .. the problem is, the next dialog depends on a control in the previous one ..
My first choice would be to create a global variable for each piece of data that needs to be passed from dialog to dialog (usually, there is only one control with the relevant data) - then when, for example 'ok' is pressed, it copies the required data from the control to the global variable. When the next dialog is initialised, it simply reads the global variable..
.. but maybe this isnt necessary/too long winded
any ideas you and others have would be appreciated.
thanks, and ho ho !!

Do you mean a dialog box that contains other dialog boxes, tabbed ? I'm not familiar with the article, but any dialog you create should work using this method, however if the dialogs you refer to are all children of another dialog physically ( i.e. contained as children of another dialog ), then I'd look to the class that impliments that as to how you should deal with it.
