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.

If I am not mistaken, you have created your Project/Software in Dos Based Turbo editor then i am afraid that's not possible with the dos based compiled version executable

hi all, plz see below.
The click event...
void MyTrayDlg::OnButton1()
{
//some code..
m_cList.AddString("item_x");
}
i'm trying to call this click event in some other function like..
void MyTrayDlg::MyFun()
{
this->OnButton1();
}
everything is working fine... but i'd like to know how to simulate a Real button on click.. i mean to see the "Pressing" effect on the Button1. how to do?
Thanx n regards,
Rookie

Make a variable for the button: CButton m_Btn;
m_Btn.SendMessage(WM_LBUTTONDOWN,0,MAKELPARAM(2,2));
Sleep(400);
m_Btn.SendMessage(WM_LBUTTONUP,0,MAKELPARAM(2,2));
this is this.

Nice.. khan... but u know i'm putting this inside a loop in a worker thread..
void CQACDDlg::DevMonitoringThread()// thread
{
do
{
m_Btn.SendMessage(WM_LBUTTONDOWN,0,MAKELPARAM(2,2));
Sleep(400);
m_Btn.SendMessage(WM_LBUTTONUP,0,MAKELPARAM(2,2));
}
}
its freezing the GUI.. but not totally.. a small time slice is available within wihch if we call the CWinThread::SuspendThread().. its stopping.. but getting the time slice is very difficult.. i tried to increase the Sleep() to 1000. still i'm not able to click on the other button which fires SuspendThread().. u get me?..

do
{
m_Btn.SendMessage(WM_LBUTTONDOWN,0,MAKELPARAM(2,2));
Sleep(50);
m_Btn.SendMessage(WM_LBUTTONUP,0,MAKELPARAM(2,2));
Sleep(1000); // new one.
} while (1);
It seems that when the button is down, it does not let the parent click anywhere. So reduce the amount of time the button stays down to 50ms.
This seems working somewhat.
I feel lost on this one!
this is this.

Which would be the expected result when a thread sends a message to a control that it does not own. Post the message instead.

I have design a dialog include some button to click. I want to set a default button that when I press enter from the keyboard, it will just like I click on that button.
|
|
|
|
|
Include this style for the button:
BS_DEFPUSHBUTTON
Or in the dialog editor, set the "Default Button" property to true.
this is this.
|
|
|
|
|
You cab set the default ID at runtime using
CDialog::SetDefID(ID_OK) //Parameter is the ID value of the button that you want to make defualt

Take a look at the std::vector. It works well for that.
