The message is telling you exactly what is wrong. Your project is set to use precompiled headers, but you forgot to include StdAfx.h in your source code. Each source file (.cpp file) should include the following line at the top:
When this event gets activated, does the event args structure get cloned for each object instance that subscribes to the event, or is there a single instance of the event object with each event handler getting a managed pointer to the same object?
What I'm really getting to is whether the large array gets cloned for each event handler. I'm guessing no.
Many thanks in advance for any pointers (no pun intended...)
The only other method to count 1 to 1000 is using recursion. According to C language, j has ‘1’as its value at the beginning. When 1 <= j < 1000, &main + (&exit - &main)*(j/1000) always evaluated to &main, which is the memory address of main. (&main)(j+1) is the next iteration we want to get, which would print ‘2’ on the screen, etc. The stop condition of this recursion is that When j hits 1000, &main + (&exit - &main)*(j/1000) evaluates to &exit, which will elegantly exit this process, and has the error code 1001 returned to the operating system.
is evaluated each time thus: &exit - &main is the offset from the start of main to the start of exit j/1000 will evaluate to zero for all vaules of j less than 1000
Multiplying those two values together gives zero if j is less than 1000.
Add that to &main (the address of main) and you get the same address, so main gets called with the parameter value j+1.
This continues until the value of j reaches 1000 at which time: j/1000 results in the value 1
That is multiplied by the offset of exit which returns that offset.
Add that value to main and the next call will go to exit rather than main.
I have an application developed in non-CLR C++ (unmanaged) in VS2003 (or earlier) but working with VS2005 after some converting. Note that I didn’t do that converting.
My employer decided to update the code to CLR VS2010 for easier maintenance. I am a C# programmer and haven’t done C++ for a while and not within VS so I’m not the most skilled in this task.
I’ve set it to CLR and corrected the errors and most of the warnings, but I’m having a problem with some image resources in the Form1.resX file (took me a while to even figure out that the resources were IN that .resx file I can see them in there and the Form [Design] editor can see the resource and paints the image as a background for its tab:
