I try to get a notification when the user change the current selection in a CListCtrl.

It is possible to get one whith the NM_CLICK event (when the user clicks on it), but I don't know how to get the new selection when the user changes the current selection width the arrows ...

is there any message like TVN_SELCHANGED (for CTreeCtrl) ?

Thx.

Simply provide a handler for the LVN_ITEMCHANGED notification. The iItem member of the NM_LISTVIEW structure will be the number of the selected item. Or, you can just call GetNextItem(-1, LVNI_SELECTED).

You can hide controls via the

ShowWindow(SW_HIDE)<br />
ShowWindow(SW_SHOW)

good luck.

I did once a trick by setting a groupbox around the controls.
This groupbox' rectangle is exactly the rectangle to hide. You can then redraw your video window.

how to hide your menu I don't know.
here's some sample code I've used.

	//get the right points & distances to redraw the grid.<br />
	CRect filterrect;				//rectangle of filter group<br />
	CRect flexlistrect;				//rectangle of list<br />
	CRect hsbtnrect;				//rectangle of hide show button<br />
	CWnd* pWnd;<br />
	pWnd = (CWnd*)GetDlgItem(IDC_STATIC3);<br />
	pWnd->GetClientRect(filterrect);<br />
	m_lstActivations.GetClientRect(flexlistrect);<br />
	m_btnhideshow.GetClientRect(hsbtnrect);<br />
<br />
	topoflisthidden = hsbtnrect.bottom + 15;<br />
	topoflistshown = filterrect.bottom + hsbtnrect.bottom + 15;<br />
	bottomoflisthidden = flexlistrect.bottom + filterrect.bottom + hsbtnrect.bottom - 5;<br />
	bottomoflistshown = bottomoflisthidden - (filterrect.bottom);<br />
	widthoflist = filterrect.right;

<br />
	if(showed == false){<br />
		sortcol = 2;				//sort on patients<br />
		//hide all filter controls<br />

I want to implement Client/Server Application between Windows and Solaris Machine.Client can communicate to different Solaris Machines.How to handle Multiple socket connections and all socket connections I want run as threads.
Can give any idea or any examples please.

hi ,

Ur question does not describe the context in which ur running ur application.

I am assuming that ur running a custom TCP/IP server seevice on a solaris
machine. (Otherwise , how ur Client will communicate to Solaris machine ?)

And client machine seems to be windows.

If u take any book on socket programming , that will show u how u can
write a rudimentary server ( some books even deal with HTTP servers )

Basic idea is as follows

ur server will wait for the connection. There are steps
like calling socket function , binding the socket with protocol port address
etc.

When a client initiates a call to the server. Server will create
a new thread or task ( using posix threads package or unix fork function )
and the new request will be handled by the threads. So learn Berkely socket API , Posix threads , Unix fork etc. And try to refer following books

Unix network programming by Richard stevens is the place to go for
Linux / Unix programmers

Winsock programming by Lewis napper will give u idea about Windows socket programming

U can also read Interetworking with TCP/IP by Douglas comer. A chapter on socket programming is there.

Hello 2all!

I've a simple problem (hopefully):

My visual c++ application have to map a smb share (like typing "net use z: \\server1\c$ ...") at the DOS-prompt. How do I figure this out?
I've tried out the shellexec command but this isn't working properly.
Is there another method to access files lying on a smb share directory on a server?

i have built an application which was running fine till now as administrator. now, i tried running it as a user, it failed. Does a user do not have access to C:\WINNT\system32\drivers files. actually i am loading a driver(.sys) in my application. so when it runs as a user(other than administrator), it fails to load the driver. but it is very important that all the user logged on to the machine can run the application. also i do not want to move the driver from the C:\WINNT\system32\drivers directory. Is there any way out?

change icon when pass over a zone in a Picture control

Hi guys
I'm trying to change my mouse icon when it's passing over a zone in a Picture Control but unsuccesfully.Could you explain me what steps I have to do to implement this?
I'm trying with OnMouseMove to control the zone,and it detects perfectly my zone, but once there, how can I change my mouse icon (remember that is not a button it's a Picture control).I've tried a LoadIcon unsuccesfully.
Thanks in advance.

use m_nActiveCursor as a member to store the ID of the cursor which has to be shown

int the OnMouseMove change the cursor as you do using:
SetCursor(LoadCursor( AfxGetInstanceHandle(), MAKEINTRESOURCE(m_nActiveCursor)) );

Also set the cursor in the OnSetCursor correct.
SetCursor(LoadCursor( AfxGetInstanceHandle(), MAKEINTRESOURCE(m_nActiveCursor)) );

Hope this helps.

Hi GDavy
Still nothing happens
When the mouse is over the zone, still the arrow is shown

void CLinksCtrl::OnMouseMove(UINT nFlags, CPoint point)
{
if ((point.x>7)&&(point.x<188)&&(point.y>0)&&(point.y<23)) {
m_nActiveCursor=1; //HAND
} else {
m_nActiveCursor=32512; // DEFAULT ARROW
}
SetCursor(LoadCursor( AfxGetInstanceHandle(), MAKEINTRESOURCE(m_nActiveCursor)));

CStatic::OnMouseMove(nFlags, point);
}

BOOL CLinksCtrl::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
SetCursor(LoadCursor( AfxGetInstanceHandle(), MAKEINTRESOURCE(m_nActiveCursor)));
return CStatic::OnSetCursor(pWnd, nHitTest, message);
}

Something wrong? Cry | :((

hmm... Sorry did not notice this earlier
your values are predefined arrow and hand pointers, in that case you do not need
the MAKEINTRESOURCE macro. you need this macro if the id would be the id from a cursor you manually added in the resources.

Hi,

I have a header file which is included in 1 project which has to be included in another too. I can copy it to the other project and then include it, but when the header changes i have to copy the file again to the other location.
How can i easily maintain only 1 version of that file?

I have seen i can import a header file from another location, but when i do #include "Myheader.h" or #include <myheader.h> the header isn't found neither.

Can you help?

You need to ensure that the location of MyHeader.h is in the include path for both of your projects.

First of all, thanks for the reply.

I had included the location of 'Myheader.h' file in the first project like 'C:\vss\'. I knew it was going to be in a subdirectory of 'C:\vss'. I've now replaced it with the exact directory and now the compiler finds the file!! Really strange. (No recursive search?)

I've alsoo written a class in project 2 that needs to be accessed from project 1 alsoo. I have set my include paths correctly. It links in project2 correctly but in project1 it receives errors while linking. If i put the files in directory of project 2, the class compiles without a problem. How is this possible?
