I want to create a console application (using Visual C++ 6.0) that can input and output Arabic characters. I tried the following code:
#define UNICODE
#include <tchar.h>
#include <iostream>
int main()
{
TCHAR in[10];
std::wcin >> in;
std::wcout << in;
}
When I run the program I try to type an Arabic word, but strange characters appear (those at the 2nd half of the ASCII table). The "cout" statement does absolutely nothing. All help would be appreciated. Thank you in advance.
Look for "Hooking" or "Hooks".
Thanks for your reply, but could you point out an alternative?
Thanks for your help. I am sorry to say that your clarification missed a bit. I want to stop the secondary thread, and get out the message box. After the message box returns yes or no, the secondary thread will do work according to the user's choice. But thanks for your help anyway! :rose:
I have an API program in which I have one thread other than the main thread. In the other thread, I wrote MessageBox(globalMainWndHWND, ...), trying to get a message under my main window. The problem is that at this step the MessageBox function does not return! I thought that Windows might prevent threads from using objects created by other threads. I tried to pass the HWND as a parameter to the thread function (instead of using the global variable), but the same problem happened again. SendMessage did the same thing. Could someone please tell me how I could solve this problem? Thank you very much.
Excuse me, but is your code somehow better than the following?
struct Node { Node * children[8]; } *pRoot = 0;
void _Add( Node *pNode, Datum* pDatum )
{
if ( 0 == pNode )
{
pNode = new Node;
// assign data
memset( pNode->children, 8\*sizeof(Node\*) );
return;
}
// else
if (...) { _Add(pNode->children[0], pDatum); return; }
// ...
}
Thanks for your reply. Your code does the opposite of what I wanted. I would change it to:
{
RectList::reverse_iterator next = ri;
*ri = *(++next);
}
Thanks anyway.
Thanks for your reply. But why can't I add to the iterator? According to MSDN[^], the reverse iterator contains operator+. What I don't know is what this operator takes as input. Anyway, I changed my code to this and it compiled:
for ( RectList::reverse_iterator ri = myList.rbegin(), ri2 = myList.rbegin();
ri2 != myList.rend(); ++ri )
*ri = *(++ri2);
Thank you for your help.
I have never tried it, but may be using regions will solve your problem.
I have an STL list, and I want to move on it from back to front. I am trying to use the reverse_iterator, but I am getting a compilation error. Here is my code:
typedef std::list<RECT> RectList;
RectList myList; // The list is created and initialised elsewhere
for ( RectList::reverse_iterator ri = myList.rbegin();
ri != RectList.rend(); ++ri )
{
*ri = *(ri + 1);
}
I get the following errors in the last line: error C2784: 'class std::reverse_iterator<_RI,_Ty,_Rt,_Pt,_D> __cdecl std::operator +(_D,const class std::reverse_iterator<_RI,_Ty,_Rt,_Pt,_D> &)' : could not deduce template argument for '' from 'class std::reverse_bidirectional_iterator<class std::list<struct tagRECT,class std::allocator<struct tagRECT> >::iterator,struct tagRECT,struct tagRECT &,struct tagRECT *,int>' error C2676: binary '+' : 'class std::reverse_bidirectional_iterator<class std::list<struct tagRECT,class std::allocator<struct tagRECT> >::iterator,struct tagRECT,struct tagRECT &,struct tagRECT *,int>' does not define this operator or a conversion to a type acceptable to the predefined operator
out.close(); after you finish. This is to make sure everything is output on the file.You're welcome.
Microsoft Visual C++ 6.0 with SP5. I said it compiled, but I did not run it.
I removed it. Cheer up!
The things I will say in this reply are MS Visual C++ 6.0 specific. I have not tried them on any other compiler. 7stud wrote: My compiler does recognize "std" as a namespace for win32 console apps You probably use #include <iostream>, which includes the std namespace. But, the cmath header file does not contain the std namespace. In fact, the following code is perfectly legal:
#include <cmath>
int main() {
double x = sqrt(5);
}
But this one is not:
#include <cmath>
using std::sqrt;
So you don't need to use the std namespace if you are going to use cmath in Visual C++ 6.0. Hope this helps.
I am happy it worked! :-D
The following code compiled correctly:
template <typename T>
class Node { public: T data; };
typedef template<typename T> Node<T>* pTnode;
pTnode<int> p;
As I tried to look it up, I saw that you may be able to handle it as follows:
case WM_KILLFOCUS:
if ( wParam != 0 )
{
WINDOWINFO wi;
GetWindowInfo( (HWND)wParam, &wi ); // sorry, did not check for errors
if ( (wi.dwExStyle & WS_EX_TOPMOST) == WS_EX_TOPMOST )
{
SetWindowPos( (HWND)wParam, HWND_TOP,
0, 0, 0, 0, // ignored
SWP_NOMOVE | SWP_NOSIZE |
SWP_NOOWNERZORDER | SWP_NOSENDCHANGING );
}
}
return 0;
Hope this helps (and hope I am not wrong!).
I hope I will not waste your time. I am a beginner and had never tried making my window on top, but I think that you do it by setting the window's style. I have an idea, but I do not know whether it is correct or applicable. If an application presents a message box, then your application will lose focus. May be you could handle WM_KILLFOCUS (or OnKillFocus()) and test the window getting focus for its style. If the style contains on top (and maybe message box style), put it somehow in front of your app (I think you would need to change your app's Z-order to make it after the message box). Hope this helps, and sorry for anything wrong I may have said.
Since you are asking country-specific questions, I prefer to answer this one by e-mail. I sent you an e-mail with my address, so send me one with yours.
