Now your first line (#include statement) is incomplete.

no no, it writes
#include < iostream >
there, but editor took it as a tag.
I really couldn't why this error is coming from.

You need to remove blocks of code until the error goes away, then start adding them back until you identify the problem.

But I have friend, the all code is this. Can you take a look at it in your compiler? There is no unmatched curly bracket as far as I see. If someone can point for me I will be glad to see it?!

|

just insert this one as the very first line of your code:
#include "stdafx.h"

Thank you very much it worked. But this tme I got the errors like
hw2 error LNK2019: unresolved external symbol "void __cdecl selectionSort(int * const,int)" (?selectionSort@@YAXQAHH@Z) referenced in function _main

I've just received and application that has a COM Autmation interface (not sure if I'm describing that right). I need to write an application that will interface with it. Can anyone suggest a tutorial that will cover a way to do this?
Thanks

Yeah I looked thru here, but I'm not sure if they are talking about making an automation server or interfacing with one. On top of that there are none for how to do it with the .NET studio.

i need to create security events such as failed login and success login events, and looking for a tool that will automate login attempts (will need to run repeatedly). i've been searching for one and can't find it. or maybe API? thx

You could write a small console app using the LogonUser and LogonUserEx function calls. Put calls into some loops using whatever user information you want - valid or not, for your testing.

Hello,
sometimes I got a network cable disconnect or network cable unplugged event, and I would like to develop a small app to check when it happens and to log it, what api should I use??
Thanks in advance

Put a breakpoint on the SetupDiCreateDeviceInfoList() statement and single-step through the code until you get to the statement that causes the error.
I cleaned up your code a bit to look like:
HDEVINFO DoDeviceEnum( void )
{
GUID InterfaceClassGuid;
HDEVINFO DeviceInfoSet,
NewDeviceInfoSet;
DeviceInfoSet = SetupDiCreateDeviceInfoList(&InterfaceClassGuid, NULL);
if (DeviceInfoSet != INVALID_HANDLE_VALUE)
{
NewDeviceInfoSet = SetupDiGetClassDevsEx(&InterfaceClassGuid,
NULL,
NULL,
DIGCF_PRESENT | DIGCF_DEVICEINTERFACE,
DeviceInfoSet,
NULL,
NULL);
if (NewDeviceInfoSet != INVALID_HANDLE_VALUE)
;
else
printf("SetupDiGetClassDevsEx failed: %lu.\n", GetLastError());
SetupDiDestroyDeviceInfoList(DeviceInfoSet);
}
else
printf("SetupDiCreateDeviceInfoList failed: %lu.\n", GetLastError());
return NewDeviceInfoSet;
}
void main( void )
{
DoDeviceEnum();
}

I had created a structure with six members of type CString.
I am trying to send this structure using the 'Send' command.
A Pointer object is created for the structure.
At the receiving end i had created the same structure. But when i was trying to display the data , I got only a blank message box.
Can anyone solve this problem?
source prg
..........
Struct message
{
CString name;
...
};
message *obj=new message();
Send(obj,sizeof(struct message));
dest prog
........
Struct message
{
CString name;
...
};
message *obj=new message();
Receive(obj,sizeof(struct message));
MessageBox(obj->name); //blank message box was displayed ?

The problem with your code is that sizeof(struct message) is going to return the same number no matter what the size of the string. That is because the CString class has a pointer to a buffer which contains the actual string. You have just stumbled upon a problem that occurs very often. There are many ways around this, but the simpliest one I can think of would be to change your struct to:
<br />
struct message<br />
{<br />
char name[256];<br />
};<br />
sizeof(struct message) would then return 256. This method is inefficient, as the whole buffer would be transferred, and it would be tougher to work with the char arrays instead of the CString's.
Greba,

why can't we use CString instead of character arrays ?
I am in need of CString values at the receving end.Because I
have to perform some trimming operations at the receiving side.
What is the real problem while displaying the values stored in structure?
Is there any other way to send a structure through the 'Send' command?

Hi,
I'm having trouble with using a particular COM object in an MFC application. Here's what happens. I create a brand new MFC application put some code in the message handler to initialize COM, create object, set some properties on the object etc. That works fine. However when I try the exact same code inside another, bigger application the code doesn't work.
First CoInitialize() returns RPC_E_CHANGED_MODE. I have no idea why because this is the first time I call it in the code. I use many other libraries it may be possible that some other library has initialize it. I can either ignore this returned value or put CoInitialize and other code into a thread, in either case problem 2 occurs.
Second, the program doesn't behave as it should. I try to debug it by stepping through the code. CoCreateInstance() works fine, then I set some options on this created instance, that works fine. Then I call another function and MSVC++ displays "First-chance exception...(NTDLL.DLL): Invalid Handle" and I can't debug any further.
How can I debug this? This particular code is identical between the two applications. Both applications seem to have the same project settings. I'm just out of ideas.

Does anybody know how many symbols maximum, a CString object can contain ?
Thanks in advance

The amount of memory your program gets should be the limit of CString size.
|
|
|
|

Take a look at CString::AllocBuffer(). You'll notice that it is INT_MAX.

the index of a CString object is an int. could you find the size now ?

The theoretical limit is INT_MAX, or 2GB. But since the buffer has to be contiguous block of memory, and you won't be able to allocate a 2GB block in your process space, the practical limit is much less.
