stop badger WhiteSky and ask a specific question instead. tell what's your problem, where you can't do things.
people here won't do the job for you ; they'll only give you hints.

Hi,i am trying to sent structures through SOCKETS,but the information is not reaching the server. I need source code to sent structures and delimit at server side
|

Hope you would be sending commands in those structures.
you can do like this.
send this to client.
struct SomeData
{
int command;
int param1[100];
int param2[100];
}
on client side read the sizeof(int) to get the command type the structure contains.
once you know the command , you should read the 100 bytes for first param and then 100 for another param.
This way your structure will be transmitted across wire.
Hope this helps.

Thankq Mr. zubair_ahmed,
But i want 2 give clear idea abt the problem which i got.
This is the data which i want 2 send:
struct data
{
int id;
CString str1;
CString str2;
}pt;
UpdateData();
CString str;
pt.str1=m_ID;
pt.str2=m_Name;
pt.id="A";
str.Format ("%d#%s#%s",pt);
send(clientsock,str,str.GetLength(),0);
Here Iam sending structure data tru string but.. is there any way to send data by structure address??
and How to get back the data at server side
...Thanks swamy

You can send structures that don't contain any pointers or structs/classes that contain pointers. A CString has a pointer to the actual string data, so you can't send the struct in your example code code directly over a socket.

I think u have both client server on same PC. And u want to do Inter Process communication via socket.
Isn't it?

hi Divyang Mithaiwala,
Iam sending data from one sys to another sys (two seperate systems) with IP and port.

Hello swamy Narasimha,
For that u have to type cast ur struct pointer to char pointer.
But it is quit risky.
Becoz as u know that differeint platform use different size for int datatype.
And also change possion for date in struct to optimize best space.
In both of this case ur data at other end is useless.
And that's why some COM component provide fisrt field as sizeofstruct.
To conform that both end use same style for data arrangment.

Ca nyou post the code for the transmit receive that you have already ? I never worked with socket before but I suppose it works like any other 'communication' media. So for example if you are trying to pass the address of your structure, it will only transmit the address and not the content.
Can you post your code to clarify the situation ?

Does DlgDirList help?
TCHAR szPath[ MAX_PATH ] = { _T( "C:\\" ) };
DlgDirList( szPath, IDC_LIST_ID, 0, 0 );This code fills out a list (IDC_LIST_ID) with all files from C:\\ directory.
Take a look at DlgDirListComboBox too.

See
<br />
WIN32_FIND_DATA find;<br />
HANDLE handle=FindFirstFile("*.bmp",&find);<br />
while(FindNextFile(handle,&find)!=0)<br />
m_List2.AddString(find.cFileName);
FindClose(handle);<br />
and see CreateDirectory(...) for create a new directory

It is adding files only, how can i add whole attributes in a list control as report and also images,
and if i right click on it slecting the wholoe files in the list control y?
|
|
|
|
|
You said only insert files&folders for attribute did you see members of WIN32_FIND_DATA dwFileAttributes/ftCreationTime and... for inser image to your ListCtrl you can use CImageList
and 3th section i dont understand what do you need?

how can i open that files by double clicking on it?
If it is *.txt files it will be open with note pad ,if it is folder it will open windows explorer .
How can i do it?

I saw a question on codeproject about how to open files with my app but i dont know it was your question or no anyway when you double click you can use from ShellExecute but before use from this function check your string with SetCurrentDirectory and see return value if its 1 your string is directory if 0 your string is a txt file Is this your question?

Hi Everybody, i am struggling from last week to get some positive feedback from expert exchange. .. pls help me out here.
WE are using AT commands to get the signal strength. While testing in Terminal service in two Scenarios:
1. We can't create a AT command session once Modem is connected.
2. We can't connect the Modem to internet if AT command session is open
The problem is we can't use the same port to open two session. Is there a way to create AT command session with device directly instead of going through Port? Or Can we open a port in share mode?
I have also check it in VB6 and .net 2005 through code, the behavior is same i am getting "Can't open port" error.
Any assistance would be great help.

Get your Window's Handle by ::FindWindow(...) then communicate with it vi it's handle .
