Catching the enter keydown with several edit controls

Hi,
i have a dialog with several edit controls in it,each associated to a different set of commands.
I would like to catch the enter key press for all of them.

Just to make myself more clear:suppose i have 3 edit controls in the dialog.
If the user writes in the first of them and press enter,i want the A function to be called.
If the user writes in the second and press enter,i want the B function to be called.
If the user writes in the third and press enter,i want a message box to appear.

I already made some search and found something about controls subclassing.Is that the (complicated Smile | :)

) way to solve my problem?If so,how can i do that?

You set a flag of integer when ever and edit box is selected you can give the respective value to it. for example
declare this in the main header file

<br />
int val;<br />

add this event handler for each edit box

<br />
void CtabdlgDlg::OnEnSetfocusEdit1()<br />
{<br />
val=1;<br />
}<br />

and when enter is pressed you can check the value to the variable val and execute that respective function

Hi,

What about:

LPCTSTR var1 = "Test";
char a[11]={0};
strcpy(a, var1);
//or maybe this
LPCTSTR var1;
char a[11]="abcdefghijk";
strcpy(var1, a)

you can't do that if _UNICODE is defined.

if _UNICODE is NOT defined, then you can do a simple cast:

LPCTSTR lp = (LPCTSTR) a;

however, if _UNICODE is defined, the you have to perform a conversion, using, for instance, MultiByteToWideChar function [^].

Its MSDN description states like ,

CString problems from VC++ 6.0 to Visual Studio 2005

This is probably a known problem with an easy workaround, but I haven`t seen it yet.
The problem is that I want to use code written in Visual C++ 6.0 in Visual Studio 2005. When I compile I get the following errors e.g.:

CString temp = pOrder->GetItemNr();<br />

pOrder->GetItemNr() returns a const char*

the error I got is:

error C2440: 'initializing' : cannot convert from 'const char *' to 'ATL::CStringT<basetype,stringtraits>'

What can I do so that this assignment works again? Anyone got any ideas?

Thanks for any help,

Davy

Isn`t there a better way?
In my old code I have a lot of places where a const char* is assigned into a CString sometimes directly sometimes as a parameter in a function. It`s a lot of places to do this.
Frown | :(

Anyway thanks for your answer, I was affraid this might be the only solution...

What's the difference ? Both will call the same CString constructor so I don't see why it would work...

That's what I thought too originally, but doing this does make it work (compiler error is gone)

So I guess I`ll just have to do this for all the cases in my old code Sigh | :sigh:

.
Just came back from easter hollidays and now this mind-numbing job of putting CString () whereever the compiler complains... I need hollidays again Sniff | :^)

I thought that way initially. But, some how it is converting char* to wchar_t* in this case.

I certainly use this construct regularly in VS2005 and it works OK for me. What I have just checked is:

<br />
const char lpszFiles[] = "FileInfo";	  <br />
<br />
CString str = lpszFiles;<br />

essentially the same.

You haven't got unicode defined have you?

I have actually.
It`s necessary because sometimes more than 1 language needs to be displayed.
In VC 6.0 the conversion from const char* to WCHAR* used by CString happened automatically, this doesn`t seem to be the case anymore Frown | :(
