hi Frank,

sorry, that i misquoted the problem..
the problem does not come when i statically link the application. but when i run the application a system without VC++ installed, it gives the following error:

Debug Assertion Failed:
Program: C:\xyz.exe
File: map_pp.cpp
Line :128

the map_pp.cpp is a MFC file. so i do not where the probwm is. It runs fine on a machine which has VC++ installed in it.

i also want to know if there is some other way other than static linking, such that i can run by application on any windows machine irrespective of whether VC++ is installed on that machine.
Please reply soon,

CMemoryState can't help you on this as it could only detect new and delete.

How about _CrtMemState, _CrtMemCheckpoint and the supporting APIs used for _malloc_dbg?

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.

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!

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.
