You need to have something like this: FindDF(const CArray& filepathnames)

:( i put Find ( CString file , const CArray& FArray) c:\program files\microsoft visual studio\myprojects\anaktisi\anaktisidlg.h(18) : error C2143: syntax error : missing ',' before '&' c:\program files\microsoft visual studio\myprojects\anaktisi\anaktisidlg.h(18) : error C2059: syntax error : '&' C:\Program Files\Microsoft Visual Studio\MyProjects\Anaktisi\AnaktisiDlg.cpp(850) : error C2955: 'CArray' : use of class template requires template argument list c:\program files\microsoft visual studio\vc98\mfc\include\afxtempl.h(238) : see declaration of 'CArray' C:\Program Files\Microsoft Visual Studio\MyProjects\Anaktisi\AnaktisiDlg.cpp(851) : error C2511: 'Find' : overloaded member function 'double (class CString,const class CArray &)' not found in 'CAnaktisiDlg' c:\program files\microsoft visual studio\myprojects\anaktisi\anaktisidlg.h(14) : see declaration of 'CAnaktisiDlg'

Since CArray is a template class, you need to declare your array type as such. You can either use something like this CArray or to shorten things up, use typedef to create an alias for the template class: typedef CArray CArrayMembersClassArray; and use "CArrayMembersClassArray" as a variable type.

i tried FindDF(CString file , CArray < CString, CString& > FArray) and when i press OK nothing happends (pressed it many times)

Mark Salsbery

I'm sorry...what? :confused: What do you mean you "press ok"? Runtime? Design time? I'm lost :) Mark

hehehe sorry i let you alone inside forest:D Ok here i am to rescue u ! i use Microsoft Visual studio C++ 6.0 enviroment i press right click on the Class and press Add member function on the window it pop up i time Type: double Function declaration : Find(CString file , ....) and i have to press OK or cancel :D

Ohhh ok :) I've never used the add function wizard but I just tried it on VS 2003 .NET. I chose "Add/Add function.." for a class. Selected a return type typed a function name for the parameter type, I typed "CArray<int, int&> &" parameter name I typed MyIntArray clicked the Add button to add the parameter clicked Finish and the function was added to my class I'm not sure how different that is from VC 6 (I bet David Crow knows :)) Mark

double CAnaktisiDlg::FindDF(CString file , CArray < CString, CString& > &FArray) is what i create (indetifier CArray error) double CAnaktisiDlg::FindDF(CString file , CArray < CString, CString& > FArray) same :/ according to you it had to be working fine :((

Did you forget #include <afxtempl.h> in your project's stdafx.h file?

Here's an example of how to pass an array argument from the CArray implementation in afxtempl.h

INT_PTR CArray::Append(const CArray& src)
{
ASSERT_VALID(this);
ASSERT(this != &src); // cannot append to itself

if(this == &src)
	AfxThrowInvalidArgException();

INT\_PTR nOldSize = m\_nSize;
SetSize(m\_nSize + src.m\_nSize);
CopyElements(m\_pData + nOldSize, src.m\_pData, src.m\_nSize);
return nOldSize;

}

Works for me but I'm on a different VS version. I also have included afxtempl.h in my projects, although I'm not sure if the wizard uses that... You can always add the function by hand :) Mark

i because it was it wasn't visible and i thought u said did you forget to #include , in your project, the "stdafx.h" file ? And yes i didnt #include "afxtempl.h" but not that i forget ,because i didnt know i had :P

Now i include it my double CAnaktisiDlg::FindDF(CString file , CArray < CString, CString > FArray) works fine thank you onces again David :D (both kevin and mark :D)
