ok, this is what it looks like to me:
This is a solution that you need to load with Visual Studio and compile/link. When you do that it produces a static link library (the .lib file) which you then include to your imports.

For example, i want to get the virtual-key code value of the char ':'.
How can i get the value?
I love you not for whom you are, but who i am when I'm by your side

Handle WM_CHAR message , It nChar argument contain the value for each key.
BTW Virtual keycode for ':' is undefined and it is equal to 3A(HEX) or 58(DEC)

Hello,
I don't think that there is an easy way to do it, but you can always use a map:
<list> Create a separate module create a private map that on initialization maps all virtual key codes to their ASCII (or UNICODE) counterparts.
Create a routine that returns the key code for the character passed to it.
Example:
#include <map>
static std::map<TCHAR, UINT> g_KeyCodeMap;
static bool g_bInitialized = false;
static void InitializeKeyCodeMap()
{
g_KeyCodeMap.insert(std::make_pair(_T(SomeChar), VK_SomeChar));
g_bInitialized = true;
}
int CharacterToVKCode(TCHAR Char)
{
if( !g_bInitialized )
InitializeKeyCodeMap();
std::map<UINT, TCHAR>::const_iterator ci = g_KeyCodeMap.find(Char);
if( ci == g_KeyCodeMap.end() )
return -1;
return c_i.second;
}
If I remember correctly, the VK_CODES in ASCII builds is the ASCII code of the character. So the VK code for ':' is static_cast<int>(':');. I could be wrong about this though.

How to convert it in managed windows forms application
int A;
private: System::Windows::Forms::TextBox * textBox; //with number value
need to convert String type from textBox to int A;

int A = int.Parse("your string variable")
Thats what you'd od in C# or do you use -> in MC++?

No it is in C++ and it is

I had a line of code:
void CProtocolSimulatorDlg::OnBtnsend(bool condition1, char PortNo[10],char IPAddr[50], char Data[11])
It have error tell me that 'OnBtnsend' : overloaded member function 'void (bool,char [],char [],char [])' not found in 'CProtocolSimulatorDlg'
I do not how to solve it, can somebody help me...........

I suspect this means that this function is not defined in your header file. Why are you passing char arrays around ?

I think I do wrongly already. If I got 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;
SOCKADDR_IN ServAddr; // used to specify a local or remote endpoint address to which to connect a socket.
WSADATA wsaData; // Create a WSADATA object called wsaData
WORD wError; // error flag
WORD wVersionRequested; //[in] Highest version of Windows Sockets SPI support that the caller can use.
int nBytesSent, nError;
wVersionRequested=MAKEWORD(1,1); // makes a request for the version of Winsock on the system
wError=WSAStartup(wVersionRequested, &wsaData);
if(wError !=0)
{
AfxMessageBox("Windows Socket Error");
condition1=FALSE;
}
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);
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);
nError=connect(CliSocket,(LPSOCKADDR)&ServAddr,sizeof(ServAddr)); // gives the amount of storage
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();
}
}
}
}
}
Where should I write it if I design a dialog that have edit box to type message and a button to send the message?

In your header file:
void SendData(bool condition1, char PortNo[10],char IPAddr[50], char Data[11]);
in your .cpp file
void MyDialog::void SendData(bool condition1, char PortNo[10],char IPAddr[50], char Data[11])
{
//etc
}

Why don't you just take a number here ? Taking a char [] is a pretty ugly solution, even a char * is better IMO, but a std::string is the best non int solution, IMO.

You mean I write the code in the header file? Or in eg:ProtocolSimulatorDlg.h or ProtocolSimulator.h? And the .cpp file also same as what I want to ask....
|
|
|
|

You've never added a method before ? You add the declaration in the .h ( that is, just the method signature, no code ), and the full code in the .cpp file.

the declaration of the
void CProtocolSimulatorDlg::OnBtnsend(bool condition1, char PortNo[10],char IPAddr[50], char Data[11]) is missing in .h file
|
|
|
|
|
It seems that this declaration got deleted accidentally.
Just declare it in the header:
void OnBtnsend(bool condition1, char PortNo[10],char IPAddr[50], char Data[11]);
this is this.

In addition to the other suggestions, you would be wise to remove the hard-coded numbers from the parameter list (and either use empty brackets [], or use char* instead). While syntactically correct, it just creates more work than necessary if you ever decide that the variables need to be changed to a different size.

Hello
I want a dialog box to remain visible untill some loop exits. Just like, during some processing, a dialog box with "Please wait..." appears. How to do that?
Thank you

SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
That's from memory, probably wrong, but it's definately SetWindowPos to make a window topmost.
The other thing is, do your processing in another thread if you want the dialog to repaint itself during the operation.

hey guys i'm developing an app under visual c++ 2003 and i'm trying to retrieve the equivalent of windows' path %SystemRoot% using some function or class(i'm trying to retrieve C:\Windows or E:\WINNT or something like this). i'm also trying to add a key to the registry. i know this may be easy to do but i'm a real programming n00b.

In Continuation With Mr. Ravi,
you can also use GetWindowsDirectory and GetSystemDirectory

I have defined the following:
_variant_t varString ;
I would like to change this value regularly.
I am using a win32 dll and would like to do something that i would do in MFC like
std::string tag;
varString.format("C:\\Myfiles\\%s.xml",tag);
Is there any way that i can achieve the above in a win 32 environment?
