Hi,

I don't know what's wrong with below code, When I run this It always return the first record. Confused | :confused:

pRecCus->Find( _bstr_t("Code=" + strCusCode), 0, adSearchForward, 1L );	<br />
if( !pRecCus->adoEOF )<br />
{<br />
 m_List.SetItemText( i, 1, (LPCTSTR)((_bstr_t)pRecCus->GetFields()->GetItem(_variant_t("Name"))->Value) );<br />
}

Hi,

I was wondering if it is possible to access at runtime the data (e.g. AssemblyTitle) that is entered in the AssermblyInfo file? I know it in possible with the full framework, but I have been unable to find any info regarding the cf.

Any help would be greatly appreciated.

I am sure there is a very simple solution to this problem but I am yet to find it, so your help is greatly appreciated.

I am currently writing an application that has a handheld component and a desktop component. I have several classes that I need to use in both places.

The solution that looked best to me was to place the files in a seperate project, compile it as a ClassLibrary than import the dll and use them in each project as I needed to. However when I do this I have one of two problems. If I make the class library to use the compact framework, it creates problems in my desktop application, as it wants to remap referances to match the framework used by my library. If I create the library as a standard .net application, visual studio complains that it cannot use the library because it uses full .net features.

My Eternal thanks,
Andy

CArray makes me cry !!!!!!!

I have a very odd problem that made me really crazy ! Eek! | :eek:

I've an member variable in my dialog class:

public:<br />
   CArray < SomeStruct, SomeStruct > m_MrOdd;

In a function I added some values to m_MrOdd, like this:

void CMyDialog::SomeFunc1()<br />
{<br />
   m_MrOdd.Add( SomeStruct( 1, 2 ) );<br />
   m_MrOdd.Add( SomeStruct( 10, 2 ) );<br />
   m_MrOdd.Add( SomeStruct( 1, 212 ) );<br />
}

And when i want to use of values, the array show me nothing !

void CMyDialog::SomeFunc2()<br />
{<br />
   if(m_MrOdd.GetSize() == 0)<br />
      MessageBox( _T("What did you do with my array ?!!!!!!") );<br />
.<br />
.<br />
.<br />
}

I don't know what to do ... plz help me.

The intresting part is when i debug the program Poke tongue | ;-P

In Adding values, it shows that everything is ok and in using data in another function it shows there is not any value Cry | :((

Hadi

Is m_MrOdd the same variable? By the way, you should be declaring it as:

CArray < SomeStruct, SomeStruct& > m_MrOdd;

(the second argument is a reference type).

Hi dear João Smile | :)

And thanks alot for reply, You are the only one who helps me Smile | :)

Well, m_MrOdd is the member variable (public access) of CMyDialog class.
As you said I changed the m_MrOdd declaring to:

CArray < SomeStruct, SomeStruct& > m_MrOdd;

But I've still the problem Frown | :(

Can you please show the definition of SomeStruct? It may be important...

It's the real structure:

struct OrderItems<br />
{<br />
	OrderItems(){}<br />
	OrderItems(int code, int count)<br />
	{<br />
		m_nCode = code;	<br />
		m_nCount = count;<br />
	}<br />
<br />
	int m_nCode;<br />
	int m_nCount;<br />
};

Best Regards,
Hadi

This is really strange because it should be working on such a simple structure (no need for complex copy semantics). Let me think a little bit...

In Adding Function (I added 2 items to array):
GetSize() is 2, and GetUpperBound() is 1

In Using Function:
GetSize() is 0, and GetUpperBound() is -1

Hadi

Are you absolutely sure that the functions are called in this order? By any chance are you not clearing the array between the calls? (this is weired)

Yes, I'm sure ...
As you can see the code is so simple, and I didn't clear any item ...

Got it! Most of the times, we have to read MFC's source code to know whais is happening. Look:

AFX_INLINE int CArray<TYPE, ARG_TYPE>::Add(ARG_TYPE newElement)
	{ int nIndex = m_nSize;
		SetAtGrow(nIndex, newElement);
		return nIndex; }
.
.
.
template<class TYPE, class ARG_TYPE>
void CArray<TYPE, ARG_TYPE>::SetAtGrow(int nIndex, ARG_TYPE newElement)
{
	ASSERT_VALID(this);
	ASSERT(nIndex >= 0);

	if (nIndex >= m_nSize)
		SetSize(nIndex+1, -1);
	m_pData[nIndex] = newElement;
}

The code is using a reference type (ARG_TYPE) to add the objects, that you are passing as unnamed temporaries (when are these being deleted?). Try something like this:

void CMyDialog::SomeFunc1()
{
SomeStruct a(0,0);

a = SomeStruct( 1, 2 );
m_MrOdd.Add( a );

a = SomeStruct( 10, 2 );
m_MrOdd.Add( a );

a = SomeStruct( 1, 212 );
m_MrOdd.Add( a );
}

I know it looks odd, but try it.

I tried this way:

OrderItems item(0, 0);<br />
item = OrderItems( 10, 96 );<br />
m_OrderItems.Add( item );<br />
item = OrderItems( 5, 13 );<br />
m_OrderItems.Add( item );

But ...... Frown | :(
