I make a guess:
This sample [^] uses 32767, that is 0x8000-1 (Well..., actually the two things are probably unrelated...)

CString is 16 bit under unicode but 8bit under non unicode version i guess.
but
so underunicode version direct conversion can be done as TCHAR is unsigned short.
where in non unicode version, WideCharToMultiByte() can be used

You have this code
HCURSOR hcur;
hcur = ::LoadCursorFromFile((LPCWSTR)"C:\\eglobe.ani");
::SetSystemCursor(hcur,OCR_NORMAL);
This bit - (LPCWSTR)"C:\\eglobe.ani" - will not work. The string literal is of type LPCSTR. That cannot be correctly converted to LPCWSTR with a simple cast. Instead, use this:
hcur = ::LoadCursorFromFile(_T("C:\\eglobe.ani"));
The _T macro either uses the string literal ("C:\\eglobe.ani") or the wide-char equivalent (L"C:\\eglobe.ani") as necessary

Now my code is as below:
But Still it enters else bock ie.,"Failed"
CString s("Sucess");
HCURSOR hcur;
hcur = ::LoadCursorFromFile(_T("C:\\eglobe.ani"));
if(hcur!=NULL)
{
::SetSystemCursor(hcur,OCR_NORMAL);
}
else
{
s="Failed";
}
|
|
|
|
|
This worked, but setting back the curso to normal did not work ie.,last statement
Plese help
CString s("Sucess");
HCURSOR hcur;
HCURSOR hCurBusy = ::LoadCursor(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDR_ANICURSOR1));
HCURSOR hCurStandard = ::LoadCursor(NULL, IDC_ARROW);
::SetSystemCursor(hCurBusy,OCR_NORMAL);
int i;
while(some length process)
{
}
::SetSystemCursor(hCurStandard,OCR_NORMAL);

Eeep - that's the WRONG way to change cursors.
With Windows, you either set the cursor in a window's class or respond to WM_SETCURSOR[^] messages to set the cursor. Your way is changing the cursor for the whole system - people will cuss you if you do that.

Can you please help me to understand how to respond to WM_SETCURSOR
|
|
|
|

OK...you need to add a WM_SETCURSOR message handler to the window where you want your special cursor to be shown. This handler should use SetCursor to change the cursor to the one you want and return TRUE.
The form of the message handler obviously depends on what Windows framework (if any you're using) - here's an example using MFC[^].

I want to handle the WM_SETCURSOR is the view class and
Set BeginWaitCursor(); and EndWaitCursor(); in a non MFC class with
handles the lengthy operation.
Is that ok, Please advice the best way

I have made a few wrapper classes for arrays to include dynamic resizing, string indexing etc.
The classes worked fine when used on their own in an app. Now i have attempted to make a Hashtable class which uses an Array object of AssocArray objects.
When I attempt to access data by using code like ' array[x][str] = y; ' I get the following error...
error C2679: binary '[' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)
#include <string>
using std::string;
int x = 0;
int y = 1;
string = "Foo";
array = new Array<AssocArray<int>>();
array[x][str] = y;
Function for overloaded operators is very similar for both Array, and AssocArray. I have removed all code inside function as it produced the same error when commented out.
template <class TType>
TType& AssocArray<TType>::operator [](string s)
{
return new TType;
}
It is my understanding that the line ' array[x][str] = y; ' would be computed like this...
AssocArray<int> ax = array[x];
ax[str] = y;
Am I correct about this?
I'm not sure what is going on here, and assume this is all the relevant code, If you would like to see any more just ask.

does it stands for:

Array<AssocArray<int>> * array;
array = new Array<AssocArray<int>>();
(*array)[x][str] = y;

Few typos there, C#

That doesn't look quite right - typo somewhere?
Mikey_H wrote: array = new Array<AssocArray<int>>();

Similarly here - you can't use operators directly with pointers - but now I understand the error message.
The type of array is Array<AssocArray<int>>*. So, the type of array[x] is Array<AssocArray<int>>& - and that has an operator[] that takes an integer index, not a string index.
So, either declare array as Array<AssocArray<int>> array(); or use (*array)[x][str]

Ok, I did not think about that. So (*varPointer) will derefernce this?
(Is this only for user defined types? A pointer to a standard C array does not have to be derferenced does it?)
That first issue is solved with the corrections, another small one exists tho, probably a similar issue.
(*array)[x][str] = y;
will give the error....
error C2440: 'return' : cannot convert from 'int' to 'AssocArray<TType> &'
Do I need to dereference the AssocArray somehow too?
Thank you for your responses

Quite right - pointers are special cases
Think about it - you're applying an operator defined on a class. The operator syntax a[b] is equivalent to a.operator[](b). So, with a pointer to the object, you can see that the method call syntax would be pa->operator[](b), or (*pa).operator[](b).

Here's some sample code I wrote that has the operator[] layout you want:
#include <string>
#include <iostream>
template<class Element>
class Array
{
public:
Element& operator[](int index) { return e; }
private:
Element e;
};
template<class Element>
class AssocArray
{
public:
Element& operator[](std::string const& s) { return e; }
private:
Element e;
};
int main()
{
Array< std::string > as;
AssocArray< std::string > aas;
Array< AssocArray< std::string > > aaas;
as[2];
aas["Hello"];
aaas[2]["Hello"] = "Test";
std::cout << aaas[2]["Hello"] << std::endl;
}
