Hi,
I want minimize,maximize,close icon in child window.How can i do this?
I tried lot of things but failed.
The problem is..I got these icons in my child window, when i minimized it has gone somewhere, so i cudn't maximize the window again..and also when i click restoreup in that three icon(middle one) it didn't minimized to small size..nothing get changed but three icons will disappeared.
One morething these three icons didnot display when the application opens, when i switch to another window in the same application then come back to this window then the three icons appear,
What can i do?
My requiremnt is same as vc++ coding environment(i.e., we can minimize,close and maximize the text editor in our vc++ complier)I need the same functionality..Pls help me out?

hi all i had made application that send() recv() through winsock API's not the MFC classes and winsock controll.
when i send one time it works fine and receives well but when i send more than once at a time
i.e
if((send(conn,"11",strlen("13"),0))==2)<br />
AfxMessageBox("11");<br />
if((send(conn,"12",strlen("13"),0))==2)<br />
AfxMessageBox("11");<br />
if((send(conn,"13",strlen("13"),0))==2)<br />
AfxMessageBox("13");<br />
and then closing the sockets<br />
other side cannot receive anything i mean it receive 0 bytes.i m using the receive side in for loop here is the code.
for (int i=0;i<3;i++)<br />
{<br />
int numbytes;<br />
char buf[5];<br />
if((numbytes=recv(new_fd,buf,strlen(buf),0))==0)<br />
AfxMessageBox("Conn Forcefully Rejected Receive Error");<br />
else<br />
{<br />
buf[(numbytes+1)] = '\0';<br />
AfxMessageBox(buf);<br />
} <br />
}and then it closes sockets also.
but it shows the conn forefully rejected receive error.
i dont why it is this.

you just mention length '2'.
recv(new_fd,buf,strlen(buf),0)
instead use this
recv(new_fd,buf,2,0)

thanks it did worked.

It seems that you find your answer but see an article about transfer file with socket on codeproject maybe it helpful for you.
|
|
|
|

In my opinion there could be many reasons for this code not working. The most important and in my opinion the one with the brightest chances is the connection not properly set up. post the full code then may be anybody would be able to help!

Hello friends,
I have an appication of recording a wave file.
But i want to specify the sound device through which only
the wave file should be recorded. That is if my machine has more than one sound card
then i want to select one (through Programmatically) and record sound from that one only.
How to do that.
Thanks in Advance.

Hi,
I get the file size and I want to format it using the format (xxx,xxx,xxx), for example:
35456931 --> 35,456,931 bytes.
how can I do it??
Regards

Like this:
CString strNum="123467890";
int len=strNum.GetLength ();
for(int i=len-3;i>0;i-=3)
{
strNum.Insert (i,',');
}
AfxMessageBox (strNum);
Somethings seem HARD to do, until we know how to do them.

Here is some code that will format a number using the current locale settings:
std::string format(unsigned int n)
{
std::stringstream strm;
strm.imbue(std::locale(""));
strm << n;
return strm.str();
}

This version should handle any number (int, long, etc.):
template <typename T>
std::string format(T t)
{
std::stringstream strm;
strm.imbue(std::locale(""));
strm << t;
return strm.str();
}

Exactly how does this add commas to the number?

I see he gets file size so I guess its better he uses from this function (for comma CString::Format )
|
|
|
|
|
Use GetNumberFormat() to format a number with commas (or whatever you use in your locale).

Hi,
I am using Visual studio 2005 (VC.Net). I am getting a very strange error in my application when i am calling managed code function ie. When I am loading XML file through load function with System::XML::XmlDataDocument object variable. The error message is
Managed Debugging Assistant 'FatalExecutionEngineError' has detected a problem in 'C:\TestApp.exe'.
Additional Information: The runtime has encountered a fatal error. The address of the error was at 0x79f9432a, on thread 0x3d4. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.
Please kindly help me.
Regards,
KN Rao

Hello all,
i have very specific question regarding winsock
"In a network of PC's, i want to find the ip addresses of all the nodes that are running my custom made windows service"
How to achieve this. Service is made in C++ using win32 api's and i m using winsock for all networking purposes
thanks

Hi,
I dont know what is your windows service doing. But I have an idea.
You can take care of this.
The idea is that your windows service program should populate a broadcast message in your network for every time intervals. In that broadcast message you can specify your default message that includes ip address, etc.,
In your winsock program , you could receive that default message. The default message might have an IP address of the host machine.
Using this you can achive your way.

Thanks for the fast reply. Can any one please suggest me how to broadcast a packet in network. What care should i take in sender side and receiver side. A sample code would be of great help
thanks
