not sure what you mean - if its some sort of program you've written, then its quite easy to keep a 'dirty'/'has-been-modified' flag, set that when ever data is changed, inspect it periodically and save the data if it has been set.
If you mean controlling some sort of other program not written by you then you'll have to supply more information

What is the question ?
do you need help in writing files of different formats ?
or
do you need help on how to implement an auto-save feature ?

Hi there,
I found a code snippet on the web which converts an ANSI string to UTF-8 format. I implemented it in my own and it works.
<br />
char text[1024]={0};<br />
WCHAR w[1024]={0};<br />
int erg=0;<br />
<br />
strcpy(text, m_pData);<br />
<br />
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, sizeof(w) / sizeof(WCHAR));
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, sizeof(text), 0, 0);
After that 'text' is UTF-8 formatted just nicely.
Now I was wondering, why doesn´t the following (slightly altered) code not work? I just created a char* instead of char[];
<br />
char* text = new char[1024];<br />
WCHAR w[1024]={0};<br />
int erg=0;<br />
<br />
strcpy(text, m_pData);<br />
<br />
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, sizeof(w) / sizeof(WCHAR));
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, sizeof(text), 0, 0);
Thanks,

My guess is in the first example the sizeof operator can calculate the size of the array. When it comes to pointers - no such luck. Try passing the size of the allocated memory directly (preferably by using a #define):
#define ARRAY_SIZE 1024
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, ARRAY_SIZE);
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, ARRAY_SIZE, 0, 0);

int erg=0;
Try to avoid using numbers directly or hard coding instead store in a constant.
const int SIZE = 1024;
char* text = new char[SIZE];
WCHAR w[SIZE]={0};
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, SIZE);
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, SIZE, 0, 0);
So when you change SIZE, this code still keeps working.

Thanks. That to both of you. That works.
Problem is that I wanted to avoid a const size and instead use the variable size of m_pData (the original text). Is that possible?

Since m_pData is a string you can use string operations like strlen. Try this:
char *text = new char[strlen( m_pData ) + 1 ];
WCHAR *w = new WCHAR[strlen( m_pData ) + 1];
int erg=0;
strcpy(text, m_pData);
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, strlen( text ));
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, wcslen( w ), 0, 0);
Just make sure that the strings are all NULL terminated!!

Hi I am using a ADO in my project. But when i compile my code i am getting the follwoing error.
error LNK2019: unresolved external symbol "long __cdecl _com_dispatch_method(struct IDispatch *,long,unsigned short,unsigned short,void *,wchar_t const *,...)" (?_com_dispatch_method@@YAJPAUIDispatch@@JGGPAXPB_WZZ) referenced in function "public: long __thiscall ConnectionEvents::InfoMessage(struct Error *,enum EventStatusEnum *,struct _Connection *)" (?InfoMessage@ConnectionEvents@@QAEJPAUError@@PAW4EventStatusEnum@@PAU_Connection@@@Z)
I have added this in my stdafx.cpp
#import "..\..\..\..\..\Microsoft\Redistribute\MSADO15.dll" no_namespace \
rename("Parameters","ADOParams") \
rename("Connection","ADOCon") \
rename("Parameter","ADOParam") \
rename("EOF", "adoEOF") \ implementation_only
and below code in my stdafx.h file
#import "..\..\..\..\..\Microsoft\Redistribute\MSADO15.dll" no_namespace \
rename("Parameters","ADOParams") \
rename("Connection","ADOCon") \
rename("Parameter","ADOParam") \
rename("EOF", "adoEOF") \ no_implementation
Please provide any comment i am not able to find out what is to be included to avoid this linking error.

Make sure you're linking against comsupp.lib (or some variant thereof - there's comsupp, comsuppd, comsuppw and comsuppwd) - that's where that symbol is defined. There is a #pragma in the #import process that specifies to link against that library, but it's possible, I guess, that doing the #import in stdafx negates the effect of the #pragma.

hallo, i have the following piece of code , when i try to delete the lpKeyPoint i get HEAP CORRUPTION DETECTED!
LPPOINT lpKeyPoint;
lpKeyPoint = (LPPOINT)new LPPOINT();
GetCaretPos((LPPOINT)lpKeyPoint);
if(lpKeyPoint)
{
delete lpKeyPoint;
lpKeyPoint = NULL;
}
How can i solve this problem?
Thanks.

That should be:
lpKeyPoint = new POINT();

thanks it worsk,but when i move the curosor up i get a worng value of y:
CPoint* ptrKeyPoint = new CPoint();
int nCursorLine = 0;
if((pMsg->message == WM_KEYDOWN)||(pMsg->message == WM_LBUTTONDOWN))
{
if((pMsg->wParam == VK_RETURN) || (pMsg->wParam == VK_UP)||(pMsg->wParam == VK_DOWN) || (pMsg->message == WM_LBUTTONUP))
{
GetCaretPos((LPPOINT)ptrKeyPoint);
nCursorLine = ptrKeyPoint->y;
}
if(ptrKeyPoint)
{
delete ptrKeyPoint;
ptrKeyPoint = NULL;
}
}

I try again: "How do you know that y value is wrong (please provide us details)?"

the cursor stands on the second line and ptrKeyPoint->y = 32;
it sohould be 16 instead of 32 because it starts with ptrKeyPoint->y = 0; (for the first line).

Ummmm - just don't use the heap, OK - this should work just as well:
CPoint keyPoint;
int nCursorLine = 0;
if((pMsg->message == WM_KEYDOWN)||(pMsg->message == WM_LBUTTONDOWN))
{
if((pMsg->wParam == VK_RETURN) || (pMsg->wParam == VK_UP)||(pMsg->wParam == VK_DOWN) || (pMsg->message == WM_LBUTTONUP))
{
GetCaretPos(&keyPoint);
nCursorLine = keyPoint.y;
}
See what I've done there - I've declared and defined the CPoint item as a local, so it's on the stack. Then you don't need to worry about deallocation or anything. Much simpler.

But corrupting the heap is much more fun.

Hello everyone.
I'm very new to C++. I typically stay in .NET, but I can't do this in VB.
I'm writing an Explorer replacement shell and am working on capturing the system tray icon messages. I've been able to successfully create a window and can see the icon information via WM_COPYDATA messages in WndProc. I initially tried to forward those messages on to my VB.NET app using SendMessage. That didn't work so well. Everything I got was garbage.
That has me thinking of creating a C++ Win32 DLL to create window and watch the messages. Then, using a callback function, alert the host application (my VB app) of the new data.
One problem: I don't have the foggiest idea how to write callback functions! I'm new new new to C++. I'm having enough trouble wrapping my head around having more than one type of String!
Please if someone can help, I'd really appreciate it! I need to be able to send the host application a NOTIFYICONDATA struct.
Thanks,
Ray Phillips
