You're mixing float and int here.

HANDLE icmphandle = IcmpCreateFile();
if(icmphandle=INVALID_HANDLE_VALUE )
AfxMessageBox("Error");
char reply[sizeof(icmp_echo_reply)+8];
DWORD dw = IcmpSendEcho(icmphandle,inet_addr(IPAddress),0,0,NULL,reply,sizeof(icmp_echo_reply)+8,1000);
IcmpCloseHandle(icmphandle);
return dw ;
the above mentioned code when executed gives the following error
"The Procedure entry point IcmpcreateFile could not be found in dynamic link library iphlpapi.dll "
|

Try including some or all of the following in your file:
#include <winsock2.h>
#include <windows.h>
#include "ipexport.h"
#include "icmpapi.h"
#pragma comment(lib, "Ws2_32.lib")
#pragma comment(lib, "iphlpapi.lib")
It may help.

no its wont help  still facing the same error
include "stdafx.h"
#include "IPV2.h"
#include "IPV2Doc.h"
#include "IPV2View.h"
#include<winsock2.h>
#include <afxtempl.h>
#include<iphlpapi.h>
#include<icmpapi.h>
#include "ipexport.h"
#include "icmpapi.h"
#pragma comment(lib, "Ws2_32.lib")
#pragma comment(lib, "iphlpapi.lib")
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
this is list of all the includes in CPP file
|
|
|
|
|
Perform DUMPBIN /EXPORTS on both
Ws2_32.dll
and
iphlpapi.dll
and see if the function is actually exported from the DLL.
Maybe you typed the name wrong?

How come I got the following error when including my dialog1.h file twice in separate files.
The compiler brakes at:
<br />
class CDialog1 : public CDialog<br />
{<br />
public:<br />
CDialog1 (CWnd* pParent = NULL);
<br />
enum { IDD = IDD_DIALOG1 };
…<br />
};<br />
…<br />
This error is followed by the “error C2057: expected constant expression”
Thanks

Then you need to ensure that IDD_DIALOG1 exist in the following files:

first check above IDD_CDIALOG1 present in the Resource.h,
if yes then just include
#include"resource.h"
above class
if no ,look for the real id of dialog

how could I measure size of a folder(including sub-folders and files) from code? tried CFileStatus.m_size, but it seems that MFC doesnt look at a folder as a kind of file. All comments are welcomed, especially with sample code 
|
|
|
|
|
Recursively add up the size of each file in each folder. This is a trivial problem with plenty of examples available here at CP, as well as Google.

What does your code look like? According to MSDN, the path is included.

My code is as follows
May be i have mistake in it.
str gives nothing;
void CCloseDlg::OnDropFiles(HDROP hDropInfo)
{
AfxMessageBox ("Darg n drop");
LPTSTR str;
UINT n;
DragQueryFile( hDropInfo, 0xffffffff , str, n);
AfxMessageBox(str);
CDialog::OnDropFiles(hDropInfo);
}
plz make correction
thanx

Several.
void CCloseDlg::OnDropFiles(HDROP hDropInfo)
{
UINT uCount;
CString strText;
TCHAR szBuffer[MAX_PATH];
uCount = DragQueryFile(hDropInfo, 0xffffffff, NULL, 0);
for (UINT uIndex = 0; uIndex < uCount; uIndex++)
DragQueryFile(hDropInfo, uIndex, szBuffer, sizeof(szBuffer));
CDialog::OnDropFiles(hDropInfo);
}

Hi man,
I have a really urgent matter and I really could use your help
Right now, I am doing an internship in a company and unless I can finish this project correctly, I will have
to re-do my internship
Here it goes
I have to make an application (for a small brokers company) that does the following:
1- Get data from a certain data source (using dll interface) - Step succeeded
2- Turn a first thread to start reading continuous flow of data (c++ structures), transforms them to xml flow
(std::string strXml = ProcessThe Record ) and place the strXml in a Queue
In fact we have 3 Queues (each of which corresponds to the type of message)
2 StaticQueue + 1 Dynamic Queue
3- Turn another thread that creates a socket, and listens to sockets trying to connect
Each new client will start receiving data from the 2 static queues (temporary queues are used coz the data
contained in a static queue need not to be lost)
When this new client receives the static messages, he will start receiving dynamic ones from the dynamic queue
The problem is that the applicaiton is compiled and built successfully
It runs fine but after a while (sometimes half an hour, sometimes 6 hours) it gives me this error
"instruction at ... uses adress memory ... Memory cannot be written"
"Unhandled exception in ....exe NTDLL.dll 0xC0000005 Acess violation"
I tried to debug the application:
I sometimes get the cursor on this line of code : strMsg = dynQ.pop(); (Thread connection)
I have rewritten the Queue class making it a "Synchronized queue" coz I thought it was a "critical section"
We have 2 threads, 1 is reading and the other is writing to the same Queue
Here is the code of the synchronized Queue:
............................................................................................
#include <queue>
#include <deque>
typedef std::queue<std::string, std::deque<std::string,="" std::allocator<std::string=""> > > SQ;
class SynchronizedQueue {
public:
SynchronizedQueue(){ boolTurnIsTaken = false; };
~SynchronizedQueue(){};
std::string pop();
void push(std::string);
void clear();
bool empty();
private:
bool boolTurnIsTaken;
SQ myqueue;
};
std::string SynchronizedQueue::pop() {
std::string res = "";
while(boolTurnIsTaken == true) Sleep (1);
try{
if (!myqueue.empty()){
boolTurnIsTaken = true;
try{
res = myqueue.front();
if (!myqueue.empty()){
try {
myqueue.pop();
}
catch(...)
{
res = "";
boolTurnIsTaken = false;
return res;
}
}
boolTurnIsTaken = false;
}
catch(char *strQ){
res = "";
boolTurnIsTaken = false;
}
}
}
catch(...){
boolTurnIsTaken = false;
res = "";}
return res;
};
bool SynchronizedQueue::empty() {
return myqueue.empty();
};
void SynchronizedQueue::push(std::string xToPush){
while(boolTurnIsTaken == true)
Sleep (1);
try
{
boolTurnIsTaken = true;
myqueue.push(xToPush);
boolTurnIsTaken = false;
}
catch(...){boolTurnIsTaken = false;}
};
void SynchronizedQueue::clear(){
while(boolTurnIsTaken == true) Sleep (1);
std::string strWhat;
try
{
while (!myqueue.empty()){
boolTurnIsTaken = true;
strWhat = myqueue.front();
myqueue.pop();
boolTurnIsTaken = false; }
}
catch(...){boolTurnIsTaken = false;}
};
............................................................................................
The main 3 threads in my application are the following:
- ThreadGetMessage: Read messages from the provider + converts them to XML + Fill the Queues
- ThreadTreatMessage: Creates a server socket + listens to connected clients
Each newly connected client will get the static messages and afterwards it'll start getting dynamic msg
_ ThreadConnection :
Broadcast XML Converted Messages to all Connected Clients
We do not take into consideration the status of the Client
This thread works apart from from the thread that adds New
Clients and provide them with static messages
I am really desperate
Please, your help would be greatly appreciated

hi...
I have no clue in my troubles.
I hope somebody can help me.
Question: How can I prevent from capturing a screen capture utilities or PrintScrn key?
thanks in advance!
|
|
|
|
|
basically you can prevent Printscrn keystoke using the Windows Keyborad hook.
there is dozens of pretty gud article on hook at cp just find using keyword "hooks"
|
|
|
|
|
thanks for your reply.
I understand what you mean.
If i hook the key stroke for print screen, i will prevent from screen capture. OK.
But, I still have a question.
How can i prevent from screen capturing by image capture utilities?
