It too long to be elaborated, this is the sample codes that I found in the MSDN.

You cannot directly store string values into the item data parameter of a combo box. You can only store DWORDs (unsigned long), or other valid numeric casts.

What you may be after is the text that you populate the combobox with. In that case you need to call GetLBText().

e.g.:

<font color=green>// Get and print text of current selection</font>
CString strText;
int nSel = m_ComboBox.GetCurSel();
if( m_ComboBox.GetLBText(nSel, strText) != CB_ERR )
{
  std::cout<< (LPCTSTR)strText << std::endl;
}

Hi,

After installing a WINZIP which adds it's option in WINDOWS default right-click menu. i.e. whenever we select any file and right-click then we see the WINZIP option in MENU.
I want to add my own option in WINDOWS right-click menu just as of WINZIP.

Is there any idea ?

Thanks in advance.

Bikram Singh,I used SetFocus,also SetForegroundWindow,and SetActiveWindow.Everything is OK.But when I set focus combobox(containing playlist),Windows repaints Windows Media Player, so I can't select any item in this combobox.
For other commands such as Ctrl+P,Alt+Enter,..it's ok,only for combobox,i can't choose any item.

global array pls pls help

hi guys i hope you can help me i've been stuck for hours now...

i have 2 *.cpp files

file1.cpp has an array of a structure:

struct vertices_structure
{
int array_pos;
int adjacentVerts[20];
};
vertices_structure vert[200];

in file2.cpp i have declared the structure array as extern:

extern vertices_structure vert[];

and now i wanna use the array in a normal way like any other array.
example:

int muh=vert[0].array_pos;

but that doesnt work at all.
there are NO error messages when i compile the code, but i know it doesnt work. i cant use vert[] as normal array either in file1.cpp nor file2.cpp.

cause when i run the debugger the vert[] isnt shown as array but its shown as a pointer. when i delete the row above with "int muh..." from file2.cpp the debugger shows vert[] as array again and everything works normal as its supposed to be.
can someone explain that and helpme here?

I do not see any problem. The variable vert is a pointer to an array of type vertices_structure. The [] (brackets) are just away to access the items in the array.

If you did something like this:

vertices_structure temp;
vertices_structure* pTemp = &temp;

int muh = pTemp[0].array_pos; // no problem
int muh = pTemp[1].array_pos; // RUNTIME ERROR there is only 1 item being pointed to.

Good luck!

dll function calls

how would i go about allowing a dll to call a function in my program? i have a hook setup in the dll in which i append a few items to the system menu of all applications, and based on some settings in my main application i would like to append different menu items.
should i pass a function pointer? or is there some easy magical way to do this? thanks.

No magic. Pass an object or a function pointer or give the dll a window handle and have it send a message to the window or... anything else you can come up with that does not rely on magic. Big Grin | :-D

plotting cpu and mem consumption

16-Jun-04 14:32

Hi Group,

for a project[1] I am trying to find an OS independant way to measure the amount of cpu usage

and memory consumption of the program. It would be nice if I could do that in my C++ code, so I

can show the results at runtime or even plot a nice graph (I got wild dreams).

After some google'ing I found some (nice) examples[2] but they are all windows based. Does

universal code for this problem exist?

Of course I can make different classes (one for windows and another for *nix), I do something

similar to assign sockets. But then I also need code for *nix, without using bash-scripting of

course.

So I am looking for something OS independant, but examples for windows or *nix can help me out

for now as well.

Goodnight everyone and thanks in advance,

Highly unlikely. The best you could do is write generic code for the other parts of the application and write OS specifics in wrapper DLLs keeping a common interface for each wrapper you create.

Yeah, I kind of gave up the search to "universal code" (I just like the sound of it (- Smile | :)

. I guess I'll have to write separate implementations for each OS and use conditional compile statements in the source code.

Another major problem is that I haven't found interesting code concerning memory consumption. Until now, I only found ways to measure CPU-cycles and only for windows. Can anyone help me?

Many kind greetings and thanks in advance,
