the application is a chess application. consisting of a desktop client, a server application.
it is 3 years old now and it dates back to my 4th university year.
now i am trying to make radical changes to the code and also the interface so i can be able to deploy it.
from the one hand those refrences are because of neglectiona and lack of experience (i could have use the project ressources and use LoadString) since it was my first big app in my life..
from another hand, really it was unavoidably in many cases not to hardcode some strings.. in fact just for a small example, there was a parsing code that parses a chess PGN file, and looks for keyword, and tags,etc, then it takes the moves body and decrypt it as well by matching other keywords and entering recursively inside the recursive annotations..
finally there have been and even now still is a habit such I never for example use an enum, or an #define something..
I always use string even for my context data
for example if I have a base Session class.. then I put a type as member, then you will find something like :
CSession* pSession=??
if pSession->getType()=="machine Vs machine";
CMachineVsMachineSession* pMachineBattleSession=(CMachineVsMachineSession*) pSession;
pMachineBattleSession->relayUserPieceMoveAsAnnotationMove(...
that's becuase I have plenty of things and srtructures representinf plies, piece types, castling, session type with server, user account type,
so that I decided and stiil use the String, so that I code fast, because my memory remembers by text not by the enum keyword I would have put instead...
My shif to unicode was because of many things :
I want to nable internationalization of the app. at least I want to be able to let arab chess players be able to send arabic characters in chat during chess play.
also the look of the app, differes when you change charSet to Unicode (something I do'nt understand)(for example the dialogs andbuttons)
also there was an unavoidable dependence on Unicode thirdparty libraries. liking to them with MBRS creates linking pbms.
Fianlly I recently have had a big big problem with MFC extension DLL :
as I was separating some UIs ibnto extension DLL, some drag and drop featuers and focus pbms happens when they are hosted in the MFC client app which MBRS. this was explained, but after resolving many pbm, it lokks that evrything works fine for me if I integrate that DLL inside a Unicode simple app.
I hope I explained to you the situatiuon and that now I look less incompetent.

Here is what MSDN says about this:
" If the string is found, this method selects the string in the list box and copies it to the edit control."
My code finds the string but does not do anything to the Form view edit part of the combo box dialog.
What did I missed?
CString strText;
CComboBox * pBoxOne;
pBoxOne = ( CComboBox *) GetDlgItem(IDC_COMBO1);
int i = pBoxOne->SelectString(-1,"21"); // OK
pBoxOne->GetLBText( i, strText); // OK
m_strBand = strText;
Using VC 6.0
Thanks for your help.

Use a control variable for your edit control along with SetWindowText(), or call UpdateData(false); after you change the value of m_strBand from the program. I will suggest you to use a Control variable instead of calling UpdateData() for all good reasons (Google for "avoid UpdateData").

Depends on the version. It was a MDI until version... (I don't remember  ). Now it si SDI.
MFC App wizard provide templates for both types of application.

Not only now, Word 2003 is already SDI. New document doesn't open a new document inside the frame, it opens another instance of the application. I don't honestly remember if Word 2000 was already SDI or still MDI.

Too long to be explained in an answer. I think you should try searching a bit of info, read the help of VC++ about MDI-SDI and if you don't understand something more concrete, then ask... But such a question... is going to have no "right" answer for you.

Hai, I am confused about Hessian.
Hessian is 2nd order differential of Gaussian. And has matrix 2x2.
Now, what number is in Hessian Matrix.
example:
Gaussian equation = F(x,y)= (1/(2*pi*T^2))exp-((x^2+y^2)/2T^2)
Then,
H = [Fxx(x,y) Fxy(x,y) ;
Fyx(x,y) Fyy(x,y)]
So, what is significant number of matrix content? Then this matrix will be convoluted with image.
Please, If u know, answer that question, Thanks Before.

Nope. More generally, the Hessian matrix is the square matrix of second-order partial derivatives of a function [^].

@Codeproject
Sorry,I have a mistake.
Yes, I mean, Hessian Matrix is the square matrix of second-order partial derivatives of a function. The Function I used is Gaussian Function. Please, what is exact contents in Hessian Matrix?
Gaussian Function = F(x,y) = (1/(2*pi*T^2))exp-((x^2+y^2)/2T^2) where T is scale.
mask (Hessian) 2x2
H=[a b
c d]
H = Hessian Matrix.
a=...?
b=...?
c=...?
d=...?
please, i am waiting your reply. thank You

If I remember well old good math (i.e. please check)
Fx = -(1/(2*pi*T^2))x/T^2 exp(-(x^2+y^2)/2T^2)
Fy = -(1/(2*pi*T^2))y/T^2 exp(-(x^2+y^2)/2T^2)
hence
a = Fxx = (1/(2*pi*T^2))(x^2/T^4 - 1/T^2)exp(-(x^2+y^2)/2T^2)
b = Fxy = (1/(2*pi*T^2))(xy/T^4) exp(-(x^2+y^2)/2T^2)
c = Fyx = Fxy
d = Fyy = (1/(2*pi*T^2))(y^2/T^4 - 1/T^2)exp(-(x^2+y^2)/2T^2)

Guten Tag, Mr. Kindman - CPallini.
I am glad to receive ur reply.
Now that 2x2 matrix will be convoluted with original image.
Do U know what are x, y and T ? What value is these (x, y and T)? So that I can know values of this matrix.
I will apply this matrix on Visual C++.
And please visit mywebsite:

I dont know what you mean by significant number of matrix but you know the function you know the form of matrix then what exactly is the problem?
H = [A B ; C D]
A = Fxx(x, y) (second derivative of F w.r.t x)
B = Fxy(x, y) (derivative of F w.r.t x and then w.r.t y)
C = Fyx(x, y) (derivative of F w.r.t y and then w.r.t x)
D = Fyy(x, y) (second derivative of F w.r.t y)
Now you know the analytical form of F so can't you find the derivatives yourself?

My application has a CFrameWnd which contains a CTreeCtrl. So that the user can easily delete an element from the tree I have set up an accelerator so that the Delete key issues an ID_EDIT_DELETE command. So far so good.
The problem comes when I want to do an inline edit of an element in the tree. The delete key is still issuing the ID_EDIT_DELETE command - I can stop it deleting the element by putting a guard set between the TVN_BEGINLABELEDIT and TVN_ENDLABELEDIT events. But this is not a behaviour that I want. I want the delete key to act as normal during the label editing.
Is there any way to temporarily suppress the accelerator keys during label editing?

Solved it thanks to a colleague.
I need to override the PreTranslateMessage message in my tree control class (it was already subclassed so that it wasn't a problem) as follows:
BOOL MyTreeCtrl::PreTranslateMessage(MSG* pMsg)
{
if( pMsg->message == WM_KEYDOWN )
{
if( GetEditControl() &&
(pMsg->wParam == VK_RETURN
|| pMsg->wParam == VK_DELETE
|| pMsg->wParam == VK_ESCAPE
|| GetKeyState(VK_CONTROL)))
{
::TranslateMessage(pMsg);
::DispatchMessage(pMsg);
return TRUE;
}
}
return CTreeCtrl::PreTranslateMessage(pMsg);
}

Hello all,
I created some interfaces and deployed them in an MFC extension DLL.
I have an example of an exported TreeCtrl which has a memeber that triggers the creation of a modal dialogBar.
first of I created that tree control inside a window of a client program which is linked to that DLL.
First I have seen problems with the drag and drop. infact my tree control has buit in drag and drop feature. That features happens to function only once !
I didn't comprehnd this problem until I tested the modal dialog ofwhich creation is triggered by a member of that imported Tree.(the code of the dialog also resides in the DLL) : it happens that I can't do anything with tyhe Dialog: nothing is responsing : unless I click 3 or 2 times on the taskbar icon of the application.
did anybody encountered and understood this phenomenon ?

ok, i tried to make this code awhile ago, and it doesnt work at all, and i was wondering if someone could help me figure it out?? But please, not to sound rude, but for the sake of learning something, try to explain it in the simplest terms you can what was wrong, so I can avoid doing that mistake again
#include <iostream>
#include <iomanip>
using namespace std;
void main()
{
int i,
j,
number;
cout<<setw(40)<<"Multiplication Chart"<<endl<<endl;
cout>>"This is a multiplication Chart"<<endl<<endl
cout<<"please enter a number between 1 and 17 for the table to reach up to. Numbers larger then 17 will NOT work"<<endl;
cin>>number;
for (i=0; i<number; i++)
(
cout<<i<<"I";
for (j=0; j<number; j<+)
cout<<setw(3) i*j;
}
cout<<endl;
}
system ("PAUSE");
}
