I am using .NET and if i open CLR project i can use this web service methods but If i open a regular command c++ project and then i add web reference into it, i cannot use webservice's methods.

Thanks for your reply but this link is related with clr programming. As i said first post i did connection using this method but i need exactly c++ project (without clr) and i want to connect in webservices
Is there any example?

Hi all,

I m trying to make a linked list. in which three items are present...
when i display the item only last item is displayed and it runs infinetly....
i Suppose all the three items are written at one memory location..
the code is as follows..

struct node
{
	char str[23];
	node *nxt;
};

node *start_ptr ;
void insert();
void display();

int main(int argc, char* argv[])
{
	insert();
	//display();
	return 0;
}

void insert()
{
	node *temp = new node;


	start_ptr = temp;

	for(int i = 0;i<3;i++)
	{
		cout<<"\n enter the name ";
		cin>>temp->str;

		temp->nxt = temp;
		temp = temp->nxt;
	}
}

void display()
{
	node *temp2 = start_ptr;

	while(temp2->nxt != NULL)
	{
		cout<<"\n Name = "<<temp2->str;
		temp2 = temp2->nxt;
	}
}

can anybosy help me in this

thanks in advance

The problem is that you create only one node and you make it point to itself for the next element. You need to create 3 nodes and make them point to each other.

Another problem is when you display your list afterwards: the nxt pointer of the last element is never initialized to NULL so if you fix the first problem, you'll probably get a crash.

You may also consider using std::list for that purpose Wink | ;)

MOdified: according to Cedric Moonen the next of the last node has to be set to NULL.

You linked a node to itself. Change the function

    temp->nxt = temp;
    temp = temp->nxt;
  }
}

into:

void insert()
{	
  node *temp;
  node *prev = NULL;
  
  for(int i = 0;i<3;i++)
  {
    temp = new node;
    if (  prev )
    {
      prev->next = temp;
    }
    else
    {
      start_ptr = temp
    }

    cout<<"\n enter the name ";
    cin>>temp->str;
    prev = temp;
  }
  temp->next=NULL;
}

I have NOT made a test, but it should work...

now i want to display all the three items also..

thanks in advance

That was the second problem I described. Just add a temp->nxt = NULL; just after temp = new node; in your insert function.

Even better: provide a default constructor for your node structure and in there, initialize tmp to NULL so that you never forget to do that Smile | :)

hmmm. looks like you only add one item.

node *temp = new node;
start_ptr = temp;

After that, the for loop is pretty much much non-sense.

Try to think it over and do your analysis on paper, draw boxes (for the node) and arrows for the next pointers.

At risk of stating the obvious:

This is obviously homework. That's fine, you've tried to do it yourself and asked for help, which is what the site is for. But, while I think everyone should write a linked list class, and a dynamic array class, at a minimum, once you've done that, for any code you write, you should use std::list and std::vector as your containers. You should write them to understand how they work, and what their relative cost is, and their strengths and weaknesses are. So, once you've learned from writing this class, don't make the mistake of using it for any future projects Smile | :)

Disabling Controls

gunner_uk200030-Mar-07 1:10

30-Mar-07 1:10

I have the written the following method for disabling some controls:

void RecordImageWindow::SetImagePanelEnabled(HWND hDlg, bool enable){<br />
	SendMessage(GetDlgItem(hDlg, IDC_TXTIMAGEFILELOCATION), WM_ENABLE, (WPARAM)enable, 0);<br />
	SendMessage(GetDlgItem(hDlg, IDC_COMBOIMAGEFILETYPE), WM_ENABLE, (WPARAM)enable, 0);<br />
	SendMessage(GetDlgItem(hDlg, IDC_CMDIMAGEFILELOCATION), WM_ENABLE, (WPARAM)enable, 0);<br />
<br />
}

I've checked the LRESULTs and called GetLastError and there are no problems, however none of the controls get disabled (the enable parameter is false). The text box gets greyed out but input can still be typed into it and the other controls are still usable.

Is WM_ENABLE the correct flag to send in order to disable Dialog controls? or should i be using something else...

use EnableWindow Function

GetDlgItem(hDlg, IDC_TXTIMAGEFILELOCATION)->EnableWindow( FALSE );

WM_ENABLE message is actually a notification send by windows when a window is enabled or disabled.

The Solution:

void RecordImageWindow::SetImagePanelEnabled(HWND hDlg, bool enable){<br />
	EnableWindow(GetDlgItem(hDlg, IDC_TXTIMAGEFILELOCATION), enable);<br />
	EnableWindow(GetDlgItem(hDlg, IDC_COMBOIMAGEFILETYPE), enable);<br />
	EnableWindow(GetDlgItem(hDlg, IDC_CMDIMAGEFILELOCATION), enable);<br />
}

Thanks for your help, mate.

How ever your code will create compilation error.

you need to modify it as

GetDlgItem(hDlg, IDC_TXTIMAGEFILELOCATION)->EnableWindow( enable );

or

::EnableWindow(GetDlgItem(hDlg, IDC_TXTIMAGEFILELOCATION)->m_hWnd, enable);

It compiles and runs fine.

GetDlgItem returns a handle to the dialog item, so it can be passed in as the parameter for the EnableWindow method.

You can't call Enable window from it as HWND is just a handle and had no Enable window method.

What Navin is talking about is MFC function CWnd::EnableWindow, and what you are talking about is win32 API EnableWindow. So its correct in both cases.
