hello,
I created a dialog based application.I pop up a modal dialog from the menu created in my application.Class midialog is associated with this dialog resource.By mistake i created an obj of this class in the menu handler as shown in code below.
OnMenu()//handler in my application dialog class.i.e.main dialog
{
midialog m_d;
m_d.DoModal();//creating my modal dialog
}
after couple of daysi realized that i wanted the obj not inside the handler but in the class CMainDlg(class of the main dialog).So i removed above code
and tried to declare a variable of type midialog m_d(again,suppose).then i wrote menu handler as
OnMenu()
{
m_d.DoModal();
}
midialog m_d; declared as public variable.But on compilation this code gives error.why?
syntax error : missing ';' before identifier 'm_d'
midialog' : missing storage-class or type specifiers
m_d' : missing storage-class or type specifiers
These errors are given at the declaration statement of variable
please help
thanks

You probably need to include the header where the dialog class is declared.

hello,
in the parent dialog class i have included the header for my dialog class.is it necesary to declare it at some specific locatuion;like at start of parent class .cpp or whether at start of .h
please help
what might the problem be?
thanks

You have to include it in the .h file as the variable is declared in the class itself (so in the .h file).

TAPI 3 is a COM based api where as TAPI 2.x is a standard Windows API (dll). They are very different in their approach and concept.

TAPI 3 is a COM based API. If you know how to use COM in C++ then you shouldn't have any problems with the MSDN samples.
As TAPI3 is COM based, you can probably use it directly from VB.
Of course, depending on your application, you may find that TAPI3 offers nothing that your TAPI2 code doesn't already do.

Waste of time!
The only reason for convering a 2.0 (or even 1.0) tapi version of an application into the latest version, is if you are going to use features that are provided by the latest version.
Each new version of TAPI contains the interfaces for every previous version of TAPI. Therefore, even if the TAPI DLL on a given system changes, your application will still work.

Hi, I need to use the Calander control in my MFC dialog app. The user must be able to select multiple days and once selected, when a button is pressed, circle them and/or output the dates.
How would I go about getting data out of the control?
I cant seem to find much help with this topic.
Thanks

Hi,
I don't think you can circle the selected dates, unless you do owner draw, if that is possible with this control. But you can have multiple selection and retrieve the selection easilly. Multiple selection seems to be limited to one week though. Just set the proper attributes (styles).
Also, you might want to look at the BCG Date Time control, which seems to be available for free and might do what you need. http://www.bcgsoft.com/download.htm

This is the default value. Sending the MCM_SETMAXSELCOUNT message allows this to be changed.

Hi, everyone.
I have made dialog, and i call it through button on toolbar. In that dialog there is tree control with checkbox. My Question is when i close the dialog (click button OK), how i save state of tree control so when i call this dialog again the state of tree control same like before i close the dialog.
Thank you.
|
|
|
|

When you close the dialog create an in-memory object that can build the tree again as it was when re-loading the dialog.
good luck.
No hurries, no worries.

Sorry, but how i connect the tree with data/member in other class ?
I make class CMyTabControl (CTabCtrl). In this derived class, there is a struct ZZZ that i want to access.
I make the object of this class in a class View (childviewxxx).
This view is child from the childframexxx,which have the toolbar button that call this dialog. Condition of the tree is connected with the struct.
Thank you.

there are several ways to do this.
- Use a struct.
- copy the tree into a dummy tree (kept in memory but not shown on the screen)
- use xml and put that in a string.
I think xml will use the least memory, but rebuilding your tree will probably take a little longer.
anyway you can use anything you'ld like as long as you save enough data to rebuild your tree as it was.
good luck.
No hurries, no worries.

I already design a dialog to send data. It includes a edit box to enter a message and a button to send but I still do not know how to start to write the code to send the data.I want to ask the code should write under the send button or under others button. The dialog also includes 2 radio button which is MODBUS and the other is MEWTOCOL to choose. Please help me ......I was no time to finish my project already.......

Send data to... ???
Maybe you need a button Send with the ID: IDC_SEND. Then add a message handler (I assume you use MFC): ON_BN_CLICKED(IDC_SEND, CYourDlg::OnSend). In this message handler, you send the data to your destination:
BEGIN_MESSAGE_MAP(CYourDlg, CDialog)
ON_BN_CLICKED(IDC_SEND, CYourDlg::OnSend)
END_MESSAGE_MAP()
void CYourDlg::OnSend()
{
}
Hope this helps

I have a code below:
void SendData(bool condition1, char PortNo[10],char IPAddr[50], char Data[11])
{
int _PortNo;
if(condition1)
{
_PortNo=atoi(PortNo);
SOCKET CliSocket;
// used to specify a local or remote endpoint address to which to connect a socket.
SOCKADDR_IN ServAddr;
WSADATA wsaData; // Create a WSADATA object called wsaData
WORD wError; // error flag
//[in] Highest version of Windows Sockets SPI support that the caller can use.
WORD wVersionRequested;
int nBytesSent, nError;
wVersionRequested=MAKEWORD(1,1); // makes a request for the version of Winsock on the system
wError=WSAStartup(wVersionRequested, &wsaData);// initialize Winsock
if(wError !=0)
{
AfxMessageBox("Windows Socket Error");
condition1=FALSE;
}
// Tell the user that we could not find a usable
else if(LOBYTE(wsaData.wVersion)!=LOBYTE(wVersionRequested)||
HIBYTE(wsaData.wVersion)!=HIBYTE(wVersionRequested))
{
AfxMessageBox("Socket Version Not Correct");
WSACleanup(); // reset
condition1=FALSE;
}
else
{
CliSocket=socket(AF_INET, SOCK_STREAM,0); // (AF_INET)Internet Protocol version 4
if(CliSocket==INVALID_SOCKET)
{
WSACleanup();
AfxMessageBox("Cannot Initialize Windows Socket");
condition1=FALSE;
}
else
{
ServAddr.sin_family=AF_INET;
ServAddr.sin_port=htons(_PortNo);// takes a 16-bit number in host byte order and returns a 16-bit number in network byte order
ServAddr.sin_addr.s_addr=inet_addr(IPAddr);
// gives the amount of storage
nError=connect(CliSocket,(LPSOCKADDR)&ServAddr,sizeof(ServAddr));
if(nError==SOCKET_ERROR)
{
closesocket(CliSocket);
WSACleanup();
AfxMessageBox("Cannot Connect to Display Server");
return;
}
nBytesSent=send(CliSocket, Data, lstrlen/*returns the length in bytes */(Data),0);
if (nBytesSent==SOCKET_ERROR)
{
closesocket(CliSocket);
WSACleanup();
AfxMessageBox("Send Error");
return;
}
else
{
closesocket(CliSocket);
WSACleanup();
}
}
}
}
}
So the code should write under the void CYourDlg::OnSend() or another place?

Call your function in the CYourDlg::OnSend() function and it should do what you want.
