If that WoW.exe is World Of Warcraft, and you are trying to crack the C/S protocol or create some kind of cheating (aiming/environmental) proxy, you are far out of your league if you are getting problems like this...!

Ye i get it, ill go somewhere else
-- modified at 2:24 Friday 11th May, 2007
Solved it myself by:
putting following type def at top of file:
------------Code-------------------
typedef void (CALLBACK *PTTOSEND)(SOCKET, const char*, int, int);
Instead of the default array var to hold the func pointer i created my own var like this:
------------Code-------------------
ptToSend = (PTTOSEND) GetProcAddress(hL,"send"); //type cast
The function call then looks like this
------------Code-------------------
// customizable send
extern "C" void __stdcall __E__69__( SOCKET s, const char* buf, int len, int flags )
{
//Returning response from real dll
return (*ptToSend)( s, buf, len, flags );
}

Good luck with that...!

I use a third part COM API lib. I need to pass an array of double to a method which accept VARIANT*, Is there any simple way to cast from double* to VARIANT*, I don't want to create a VARIANT array and copy each double value into.
|
|

|

The VARIANT can hold a SAFEARRAY, which you would have to populate with the set of doubles.
There is no other COM-correct way to do what you are trying to do without changing the interface (i.e. breaking the contract).

There is no other way at all, if you don't have the COM component source code (of course without hacking...).

Hi folks,
I am new to the forum and a beginner in c++ programming.
I have finished writing an application in c++ and I would now like to protect it so that only people who know the unlocking code can have access to it.
I was thinking of doing so by creating a key in the registry directory containing a random sequence of numbers and then have the program read it, perform some mathematical ops, and request the user the relative unlocking numbers for the program to run.
The idea seems simple. The only problem is that I have no clue whatsoever on how to write and read a registry key!! 
I would be very grateful for any help. I am stuck!
Thank you.

Lookup the implementation of the CRegKey class in your SDK for a good starting point, as well as the MSDN documentation for Registry-related functions like RegCreateKeyEx(...).

Dear James,
Thanks for the help.
I've looked up the RegCreateKeyEx function on MSDN, as you have suggested. I have tried to copy the code present in the second coloured box at (http://msdn2.microsoft.com/en-us/library/aa363634.aspx) into my c++ code, but I am sure I am either missing something crucial or inserting it in the wrong location, since it is returning a thousand errors when I try to compile it!
Not sure what I am doing wrong. Consider that I am a real beginner. My code is all written in c++ using VS2005 and Win32 application.
My code looks like that:
<code>#include "stdafx.h"
#include <ctime>
#include <math.h>
#include <fstream>
#include <string>
#include <iostream>
using namespace std;
#include <iomanip>
using std::setprecision;
int _tmain(int argc, _TCHAR* argv[])
{
// my code
return 0;
}</code>
Thank you!

One problem you might be having is that you are not linking with the correct libraries to support the new functions you have added.
The RegCreateKeyEx() function requires that your program be linked with Advapi32.lib. Have you added this library to you project's linker input settings?
You would add the name "Advapi32.lib" to where it says "Additional Dependencies" in the Project Settings dialog box.

Many thanks for the advice.
I have added the Advapi32.lib to the Additional Dependencies and tried to compile it (code below) but it results in many errors.
I would be very grateful for any advice.
#include "stdafx.h"
#include <fstream>
#include <string>
#include <iostream>
using namespace std;
#include <iomanip>
using std::setprecision;
int _tmain(int argc, _TCHAR* argv[])
{
CString default_server;
CString default_root_dir;
CStringArray servers;
CStringArray rootdirs;
default_server = "";
default_root_dir = "";
servers.RemoveAll();
rootdirs.RemoveAll();
/* Read FTP server name and root directories from registry. GetRegistryList reads all the key values and fill in
the CString array */
HKEY hKey = GetRegistryKey( "Server" );
GetRegistryList( hKey, default_server, servers);
/* Now read it from array and add to a combo box */
for(int i=0; i<servers.getsize(); i++="" )
{
cstring="" str="servers[i].Left(" servers[i].find("#")="" );
combo-="">AddString( str );
}
Now, here is how to add one registry entry to the registry.
AddRegValue("Server", m_szftpServerName , m_szWebRootDir );
Now, here is how to delete a key and its corresponding value from the registry:
AddRegValue("Server", m_szftpServerName , m_szWebRootDir );

I have a table filled in from reading a text file and I load that into a multi column CListCtrl, which is fine, I can also append to columns in there.
Is there an easy way to delete a specific column on a specific row?
What I'm doing right now:
a dialog button "Clear Entry" calls GetSelectionMark() on the table, and uses that to set the columns to "" in a rather heavy handed way
LVITEM lvi;
CString item = "";
lvi.mask = LVIF_IMAGE | LVIF_TEXT;
lvi.iItem = sel;
lvi.iSubItem = 3;
lvi.pszText = (LPTSTR)(LPCTSTR)(item);
m_Table.SetItem(&lvi);
lvi.iSubItem = 5;
lvi.pszText = (LPTSTR)(LPCTSTR)(item);
m_Table.SetItem(&lvi);
this seems to work fine, though there are issues
1) if the table hasnt been clicked there is no selection mark.
2) you can only click on the 1st column in a particular row - this is fine, but if I then click "Clear Entry" button, it works OK but the blue highlight disappears like that row is no longer selected but if I add data there and click "Clear Entry" it seems to remember what was last selected and deletes those items - a bit messy
I see DeleteAllItems and DeleteColumn, but how can I delete just one item on one particular row in an elegant way?

So just disable the "clear" button until a selection is made.

ldsdbomber wrote: Is there an easy way to delete a specific column on a specific row?
For a row subitem to be considered "deleted", that means its text is empty, correct?
If so, the only way I see to "delete" the subitem is to set its text to "" like you are doing.
I personally prefer to use LPSTR_TEXTCALLBACK instead of storing the text in the control.
Then when a LVN_GETDISPINFO notification is received, I can supply the text for all the items
and subitems.
This allows me to store objects of any type (representing the listview items) in any container
I prefer to use (array, etc).
Then, to "delete" an item, I can set a flag indicating the item is "deleted" or actually change
the text in my list object and refresh/repaint the control. Then the updated text is changed
the next time the LVN_GETDISPINFO is received for the item/subitem. (if that makes sense )
ldsdbomber wrote: 1) if the table hasnt been clicked there is no selection mark.
If you aren't relying on the user to select items then you'll have to keep track of what items
are in the list yourself. Another advantage of storing the data separately as I described above.

Mark,
where do I put this LVS_EX_FULLROWSELECT. I don't see that style in the dialog resource view, and have tried programmatically setting it via SetExtendedStyle, but maybe I am doing it wrong, I've created a control member variable for my dialog of type listview, which has the LVS_REPORT style via the dialog resource editor checkboxes.
I've tried m_Table.SetExtendedStyle(LVS_EX_FULLROWSELECT);
but maybe I'm doing it in the wrong place or wrong way?
|
|
|
|
|
OK I have found that and it now works, I had it in the wrong block of code
All I need now is which message I need to handle so that if the user clicks an item in the row, I can then use the SetExtendedStyle call, or can that be done in the InitDialog?
Also, I am still having problems selecting anything other than the 1st column item - I thought the FULLROWSELECT allowed you to select a row by clicking any of the items?
|
|
|
|
|
oh!
putting it in OnInitDialog seems to have done the trick!
many thanks
|
|
|
|
|
Cool! Yeah, OnInitDialog should be a good place to set the style 
Glad you got it working!

Thanks Mark.
Now, if only I could programmatically set the selected state - so that if data is added to the table in a particular row, it's highlighted as though the user clicked that row, it would be perfect. Have tried the SetSelectionMark but that doesn't seem to be it! Do you know how that's done~?
|
|
|
|
|
LVIS_SELECTED (SetItemState()) should be the message you want to use.
state, stateMask LVIS_SELECTED | LVIS_FOCUSED
You may need to remove the slected/focused state from the previously selected item(s)...
LVM_GETNEXTITEM (GetFirstSelectedItemPosition()/GetNextSelectedItem()) will help find those.

Hello,
If I have vector of int and vector of strings
vector<int>IntVector
vector<string>StringVector
and now I want to compare an int a within IntVector
and string s within StringVector
which comparison or search within these vectors will take more time.
I expect the size of vectors to be 100000.
so will it make a significant difference.

Without actually testing it myself, I'd say comparing strings would be slower.
