there are four:
error C2248: 'real' : cannot access private member declared in
class 'Complex'
error C2248: 'imag' : cannot access private member declared in
class 'Complex'
error C2593: 'operator <<' is ambiguous
error C2593: 'operator <<' is ambiguous
|
|
|
|
|
By the way,the two previous errors point to the location
"return out<
|
|
|
|
|
Because-because-because you have two different operator << overloads;
friend ostream& operator<<(ostream& out, Complex& c);
ostream& operator<<(ostream& out, const Complex& c)
{
...
}
Their prototypes are different due to the difference inside their parameter list;
in first case; Complex &
in second case; const Complex &
So make them the same; put const in the friend declaration.

To what? By making both the declaration and the definition the same, the compiler error (C2248) will go away.

What is the size of windows message queue ? i.e how many messages can queue up before the next one being discarded?
And how long can a message stay in the message queue waiting to be processed?
I've been looking all over but haven't found an answer for this ?
|
|
|
|
|
On Windows 2000 message queues defaulted to about 5000 entries which will be there until they get processed, however long it takes. I would guess that the sizes have gone up in XP and Vista and the implementation may have changed. If these limits are causing you problems then may I venture to suggest that you may have deeper problems in your design 
Nothing is exactly what it seems but everything with seems can be unpicked.

thanks a lot,
i was wondering about this just for the sake of curiousity. it's really dangerous using a queue without knowing how much it can handle. it's wierd I couldn't found any information about this (which I thing is very important). now i'm so relieved  , nobody says a word about it because it's almost limitless

It's also dangerous to make assumptions about the size of the windows message queue.
It's probably best to process the messages ASAP - for your sake and the user's sake

 I am attempt to make my software multilingual.In my application I have used CColorDialog. Now I didn't know how to translate these Common Dialog (CColorDialog / CFindReplaceDialog / CFontDialog / CPrintDialog / CPrintDialogEx) into all kinds of language version.

use runas command .. u can shellexecute runas from your program.
if u want more help type just runas in command prompt window.
If u can Dream... U can do it
|
|
|
|
|
if use "runas", i must input password when system prompt.
But all is transparent to operator , because operator just use my programme to modify files in one computer of domain and he dose`t konw where the file is!
So i must embed the username and password of the domain account created in server in my code!!!

if you know the user name and password, you can use the CreateProcessWithLogonW() function.
|
|
|
|
|
You might also want to look into LogonUser() and ImpersonateUser().

MSDN: "You cannot use LogonUser to log on to a remote computer."
The file i want to modify is in a Server!!!

It would have helped to state that requirement in your initial post.

hi guys i want some info,

When a user clickes on the header, it will get the LVN_COLUMNCLICK notication. the lparam is a NMLISTVIEW pointer. The iSubItem member of that struct will have the column number
void MyDlg::OnColumnclickList1(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;<br />
int nColumn = pNMListView->iSubItem;
}

Hi,
for the header... I'm not sure, but for normal places... you can check which item (row) is, and compare the subitems (columns).
In any case I recommend you to take a look in the CListCtrl articles that are in the site. They would explain you a lot and maybe give you some idea or direct solution.
Greetings.

Hi all. I'm working on a project to a subject in university and i'm going through a hard time trying in everyway i know and looking out in the net for solutions but i cant figure it out.
So the objective is to mix Visual Basic with a DLL made from C++. with simple functions it works, but now im calling from VB a function in the DLL sending one number and the function should go to the .txt and find the number of the line that number is. as it wasnt working i tryied in a simple c++ project with a main to do a "manual debugging" with returns and printfs. lol so here is the code. (don't mind the includes here, they're just there because they came with the copy-past from the DLL.) btw the most part of this code was copied from the internet and "moulded" to my problem.
#include<windows.h>
#include<stdio.h>
#include<stdlib.h>
#include<stdio.h>
#include<time.h>
#include<fstream>
#include <string>
int escolha_cod(double saldo,int escolha)
{
FILE *codigo;
int i=0,linha=0,j=0,aux=0;
char vec[2];
using namespace std;
string line;
ifstream myfile ("codigo.txt");
if (myfile.is_open())
{
for(i=0;i<10;i++)
{
getline(myfile,line);
const char *c_line;
strncpy(vec,line.c_str(),3);
aux=atoi(&vec[0]);
if(aux==escolha)
{linha=i;
i=10;}
}
myfile.close();
}return 47;
}
int main()
{int var;
var=escolha_cod(10,12);
printf("%d",var);
getchar();
return 0;}
If i put the "return 47;" right after "if (myfile.is_open()){" the printf says: 4403792
any idea? i would really appreciate a quick answer =) thks in advance guys!

Review your post; we can't see any of the "<" or ">" charcters or what's between them! The variable codigo seems unused.

why do i need an "<"or">" in my code?? i believe i didnt understand what you're trying to say.. 
yes codigo shouldn't be there lol its trash from others experiments lol
