Hi
I am using the following function to use the xp themes in my property page
EnableThemeDialogTexture(m_hWnd,ETDT_ENABLETAB);
The dialog looks fine when its size is small but as I increase the length of the dialog the "gradient fill" of the background seems to be tiled? Is there any way of getting rid of tiling and have a smooth gradient fill background, without drawing it all by my self?

Only the newly-exposed portion of the background gets repainted during the resize.
You may need to foce the entire background to be redrawn in response to WM_SIZE.

I seem to recall that this is a problem/limitation/bug/whatever with the texture. It's a fixed size, so if your window is bigger than that size, the texture has to be tiled.

I'm developing a program,which makes more than one person chat in the one holl. I want to using multicast.but i find that it seems that most of the routine do not surpport multicast, although i only want to send one paceage to others,I must send it for each one!
Somebody how should I do would be more effient?Thanks

What routines?
Are you using sockets?

My English is so poor,please excute me,thanks.
I mean that I want to using multicast achitecture to develop a multi-pepole chat program,which makes all the chater could chat using words or sound.
But i find that not all the router surpport multicast in the internet.
How should I dow now?
Thanks

To use true multicast then yes, you'd need multicast-capable hardware.
You can simulate multicast with sockets - the drawback being you multiply the bandwidth
requirement by the number of recipients.
You just need to keep track of all the destination addresses.
With UDP it's fairly simple since you can use sendto() to send to each destination.
With TCP, each destination connection needs a connected socket so it's slightly more complicated
(not much).
For a chat program where everyone talks to everyone, it may be simpler to have a "server" app
that everyone connects to. All messages go to the server which forwards them to all users.
That keeps the bandwidth requirement low for each user but the server needs good bandwidth.
For sound, the server could take all the incoming sound samples and mix them, then forward the
single mixed stream to all the connected users.

Hello Friends;
I want to use a web service (it has also a method) in c++.
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.
A link, document or any idea is good for me.

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();
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

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

into:

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...

thanku very much it solved my problem
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 .

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

what abt using std::list try http://www.cppreference.com

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.

Seems like I have asked the question
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);
