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

Hi 
I have a very odd problem that made me really crazy ! 
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 
In Adding values, it shows that everything is ok and in using data in another function it shows there is not any value 
Regards,
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 
And thanks alot for reply, You are the only one who helps me ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
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
Best Regards,
Hadi

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...

What is the value of GetUpperBound ?
Regards,
João Paulo Figueira

|

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
Best Regards,
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 ......

Yes I know but what can i say ? 
I'm using eVC++ 4.0 SP3, PPC 2003 SDK, WinCE 4.2 SDK is also installed.
PS: I just stop the project, don't know what the hell is this
Anyway thanks alot for your time  ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

This may well be the source of this problem. To diagnose it, I would have to take a look at your entire project.

Here's the story:
class OrderItems<br />
{<br />
public:<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 />
};<br />
<br />
class CMainPage : public CPropertyPage<br />
{<br />
.<br />
.<br />
.<br />
void UseOrders();
<br />
public:<br />
CArray < OrderItems, OrderItems& > m_OrderItems;<br />
}
And somewhere, in one of CMainPage methods I show another dialog and i add the items in that:
void COrderListDialog::OnOK() <br />
{<br />
CMainPage* dlgMain = (CMainPage*) GetParent();<br />
<br />
OrderItems item(0, 0);<br />
item = OrderItems( 10, 96 );<br />
dlgMain->m_OrderItems.Add( item );<br />
item = OrderItems( 5, 13 );<br />
dlgMain->m_OrderItems.Add( item );<br />
<br />
CDialog::OnOK();<br />
}
And then when i back to Main form i call UseOrders() to read the items but the problem occrues
I hope it's clear ...
Regards,
Hadi

Please make sure that this:
CMainPage* dlgMain = (CMainPage*) GetParent();
does return the pointer you want. If not, all is explained...

Yessss, That's it 
You solved the problem ! Thank you very much !
I changed code to this:
CAppSheet *pAppSheet = (CAppSheet *) GetParent();<br />
CMainPage *dlgMain = (CMainPage *) pAppSheet->GetPage(0);
And now it works fine ...
Best Regards,
Hadi

I did some new tests on the code that the results are strange too.
1- I declared m_OrderItems as a pointer variable and then use new, when i want to add items it shows me an error: "Out Of Memory.", But the program doesn't crash.
2- I used vector instead of CArray and i get same result. (No Item !)

Hey all, I'm working with a Phillips LPC2129 chip using a Keil compiler. In viewing the example code supplied by Keil, I noticed that they returned an 'int' from a call to a function sending a char out a UART configured as ab RS232 port.
To write to the UART the following is requiredL U1THR = <the char="" to="" be="" written="">.
The problem I have is that in the sample code provided by Keil they return that value in the 'putchar' call and I have no clue how to determine the value of the return. Moreover the manner in which a byte is written to the UART is a register write, not a function call. For example:
return( U1THR = ch );
where ch is the char to be sent. Regardless of what value ch = the return value is 'H' (0x48). I reckon my question lies in how to determine the return value of an assignment?
-any got any input on this?
