I have tried to create a CList of one/more CStringArray objects. If I try and add CStringArray to my CList I get the error:
error C2558: 'CStringArray' : no copy constructor available
Do I have derive from CStringArray and write copy constructor for my derived class? How come CStringArray does not already have copy constructor. Surely it knows the type of its elements so surely it should know how to copy itself?

Yes, in this case.

ugh... STL makes this all so easy:
<br />
#include < string ><br />
#include < vector ><br />
#include < list ><br />
<br />
std::list< std::vector< std::string > > > myStringArrayList;<br />

Sure does...all the level 4 compiler warnings are a pain though.
Although you can get rid of them, they shouldn't arise in the first place.

Hi,
I need to create a text field within a dialog box, where i want some data to be printed out (i.e., to show) .
How do I start ?
Thanks,
Deepak Samuel

I assume you already have a dialog working.
Got to the resource editor and add a static text control. Its ID is going to be IDC_STATIC change that to your own ID. Like IDC_MYTEXT. What you put as the text of the static control is going to be the text that is initially displayed.
Now, in one of your dialog message handler, wherever you want to change the text on the dialog, put the following:
CStatic* pText = (CStatic*) GetDlgItem(IDC_MYTEXT); //get a pointer to the control
pText->SetWindowText(“Hello World”); //set the text
When the message handler is called the text is going to change to Hello World.
This works with an edit box too. Make an Edit box on your resource template with ID IDC_MYEDIT. The following code will display the text.
CEdit* pEdit = (CEdit*) this->GetDlgItem(IDC_MYEDIT);
pEdit->SetWindowText("Hello World");
I hope this helps.

You might want to consider using an EDIT control instead of a STATIC, and then set the ReadOnly property on it. The advantage is that users will be able to copy & scroll the data in the control. If you don't plan on displaying all that much data, then maybe the STATIC is the right way to go.
|

Jeez, even the guys at MS don't know about SetDlgItemText.
I don't know about you, but I find a one-liner much more readable:
SetDlgItemText( IDC_MYEDIT, _T( "Hello World" ) );
Also, there's no need to cast to a CEdit or CStatic pointer if you're just going to be calling a method implemented on CWnd.

I agree that your solution is much more elegant and readable, but getting a pointer to the control is also a vital step in many other not so basic scenarios.
I figure I better answer the question the way it is most useful, not necessarily in the shortest way. That includes the cast, which might be necessary for other things besides setting the text.

To my knowledge, Visual Studio must start the application in order to debug it.
|
|
|
|
|
put __asm{ int 3 }; at the beginning of the code!
when the exception is raised, attach visual studio debugger to it, voila
Don't try it, just do it!

I am conecting to MYSQL database which is on the server using following code.
CDatabase m_dbftp;
m_dbftp.OpenEx(sDSNName,CDatabase::noOdbcDialog | CDatabase::useCursorLib );
Connection is done properly. I want to catch the exception
when server is disconnected.
I am using following code
catch(CDBException* pEx )
{
CString sz;
if ( pEx->m_nRetCode == AFX_SQL_ERROR_CONNECT_FAIL )
AfxMessageBox("myconnection failed");
}
It dose not work
Problem is m_nRetCode contains -1 instead of
AFX_SQL_ERROR_CONNECT_FAIL .
I am not able to identify if server is disconnected .? How to do it.

I see a sentence like below:
private Mutex[] m_mutex;
It seems very strange for me
What is its meaning?
Help
Thank you

Short for MUTual EXclusion. These are used to non-recursively synchronize access to shared resources. Eg: in order to protect a critical section, you can use a mutex, which will ensure that only one thread at a time can lock it.

It looks like a syntax error to me. The private keyword should have a colon after it, and the square brackets should follow the variable, not the type.
private:
Mutex m_mutex[];
If it's something different, it's new to me.

I think that's Java, or may C#. In Java, you denote the accessability of each member explicitly. Correct me if I'm wrong, its been a while since I used Java, arrays of a type are written as TypeName[] variableName.

Shouldn't C# questions be posted to the C# forum instead of the VC++ forum? You're bound to get more answers that way!
