You need to use threads;
Simply declare global function in your ...Dlg.cpp file :
UINT Thread (LPVOID pParam)
{
//// Here write your loop
for(...)
{
...
}
return 0;
}
and then add doubleclick on the Start button and add this line of code.
{
...
AfxBeginThread(Thread,0);
...
}
you can also manage this thread by changing abovewritten code with this :
CWinThread * thread = AfxBeginThread(Thread,0);
//if you want to pause this thread then use Suspend() func
thread->Suspend();
//to resume it call
thread->Resume();
Good luck

Thanx guys .. I implemented this working thread (somthing like you suggested) .. but I have one another problem ...
In that working thread I am using UpdateData functions ... and the program compiles prefectly, but when I'm starting it I'm getting ::
Debug Assertion Failure!
File: wincore.cpp
Line: 884
Pressing on ignore button repeats the Assert but in the background I can see that aplication runs well.
So, the question is :: what should I write instead of UpdateData(T/F)???
Just to say that application is Dialog based (so it has only one window)!

Are you using the newest Visual Studio SP and Platform SDK?

Im actually downloading the SP6 but dont say anything about updating the included libraries.
My platform SDK, im almost sure is really old, but i cant find it to download.
Maybe is this "Windows® Server 2003 SP1 Platform SDK"?
|
|
|
|
|
Yes... Is that, now i should wait to download 400 MB
Thanks

Yes. I'm not sure why MS deciced to give it such a name. If connection speed is the issue and you have access to a library with a broadband connection and a CD burner, see if they will let you download it. If you don't want to download it, you can buy the CD. Seems like it is around $10.

hi, i'm implementing the dijkstra's algorithm. when i complied the .dll file here comes out teh errors:
error C2664: 'TextOutW' : cannot convert parameter 4 from 'char [10]' to 'const unsigned short *'
could anyone help me deal with it?
|

Sounds like the dll is being compiled with a UNICODE configuration.
Enclose your string with TEXT() or _T("") and it should work.
This will use the appropriate string type (char or wchar_t) for this function.

Hi
How would i write c++ code to make sure that a deep copy
takes place with the following class definition?
class CShop<br />
{<br />
public:<br />
CShop();<br />
~CShop();<br />
<br />
private:<br />
CEmployeeContainer* m_pEmployee;<br />
char* m_strShopName;<br />
};<br />
An explanation will also do rather than code.
Thanks in advance.

Hello,
Your subject is the answer! Just write a copy constructor that copies all elements of the container and the string..
Example code:
<br />
CShop::CShop(const CShop& ShopToCopy)<br />
{<br />
m_pEmployee = new CEmployeeContainer();<br />
for( CEmployeeContainer::iterator i = ShopToCopy->m_pEmployee->begin(); <br />
i != ShopToCopy->m_pEmployee->end(); i++ )<br />
{<br />
m_pEmployee->insert(i);<br />
}<br />
<br />
m_strShopName = new char[strlen(ShopToCopy->m_strShopName) + 1];<br />
strcpy(m_strShopName, ShopToCopy->m_strShopName);<br />
}<br />
Hope this helps

In addition to Bob's reply, I would suggest replacing the char* member variable with a string or CString type instead. That's one less memory management detail to have to worry about.

Hi everybody,
I have several points in an array.
I want to add a code that permits that : if i stop the mouse upon one of this points on the screen show a ToolTip saying which is the order of the array of this point. How can I do it? I know that if instead of stop the mouse; it was doing button-right of the mouse I would have to call ON_WM_RBUTTONDOWN...but in this case? And if once showed the tooltip I move the mouse...how do I make it disappear? I have had a look to the codes already written...but almost all speaks about controls...and I need any point on the screen.
Thanks
Javier

IS there any limit on the maximum number of controls we can add to a Dialogue box resource in VC++. One of my application needs many controls to be added. But after adding may be around 60-70 controls on that dialogue box, now its not allowing me to add any controls. Please suggest.

Yes, 255 at design time. If you need more than that, add them at run time.

Hi experts
In my server side application i have used WSAAsyncSelect() for the purpose of setting it to non blocking mode.
The function executes successfully(returned value is 0) & waits for the client to connect.
Now when i execute my client application, it is able to connect successfully to the server but the server donot receives any notification that the client wants to connect.
Wher am i going wrong.
Waiting for suggestions.
Server side code:
BOOL CDpDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Add "About..." menu item to system menu.
// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
CString strAboutMenu;
strAboutMenu.LoadString(IDS_ABOUTBOX);
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
SOCKET server;
WSADATA wsaData;
sockaddr_in local;
WORD wVersionRequested = MAKEWORD(2,2);
int wsaret = WSAStartup(wVersionRequested, &wsaData);
if(wsaret != 0)
AfxMessageBox(_T("WSAStartup() failed!"));
else
{
AfxMessageBox(_T("Winsock version 2.2 dll loaded."));
local.sin_family = AF_INET;
local.sin_addr.s_addr = INADDR_ANY;
local.sin_port = htons((u_short)40000);
server = socket(AF_INET, SOCK_STREAM, 0);
if(server == INVALID_SOCKET)
{
AfxMessageBox(_T("Server socket cud not be created"));
return 0;
}
else
AfxMessageBox(_T("Server socket successfully created at the specified port no."));
if(bind(server,(sockaddr*)&local,sizeof(local))!=0)
{
AfxMessageBox(_T("bind() function has failed"));
return 0;
}
else
AfxMessageBox(_T("bind() function has successfully executed!"));
if(listen(server,2)!=0)
{
AfxMessageBox(_T("Server socket has failed to listen for any incoming connections"));
return 0;
}
if (WSAAsyncSelect(server, m_hWnd, WM_WINSOCK_NOTIFY, FD_READ | FD_WRITE | FD_CONNECT | FD_CLOSE) == SOCKET_ERROR)
AfxMessageBox(_T("WSAAsyncSelect() failed to xecute!"));
else
AfxMessageBox(_T("WSAAsyncSelect() xecuted successfully"));
}
return TRUE; // return TRUE unless you set the focus to a control
}

hello,
i want to use the apihook to hide a specific file or directory,not let any user to see the file and directory expect me?
what can i do?
|
|
|
|

I'm curious what a hook has to do with hiding a file/directory. Just change the security permissions of the object so that only you, or a group to which you belong, can access the object.

The print resolution of the printer (typically 600 pixels per inch) is much greate r than that of the screen (typically 72 pixels per inch) so you must use StretchBlt if you want it to appear tyhe same physical size on the higher resolution device.
