I have a combo box with 3 data:4,8,16. I'm reading a dummy file ONINIT and I would like to get the value "let's say 16" from the file displays in the combo box. How do I do that? Confused | :confused:

David Crow6-Feb-04 5:45

Are you wanting to populate the combobox with the contents of a file?

I do not want to populate it since it is already populate. I want the combo box to display or default to whatever value from the file.

Use SelectString().

how to distiguish an object send via socket

Re: how to distiguish an object send via socket

6-Feb-04 4:26

hi,

i have created an array
UCHAR * m_array;
m_array = new UNCHAR [size]

i saved data in it ,, that PCM data (pulse code modulation)

now i want to send this (array) throught socket.

but i want to place some TAG before this that helps me on server side that i m recivng an array

CString str = " <>";
E.G ..
? = str + m_array( i.e object of array )
in which(?) i store it.
m_array is not a string data;

KEEP in mind m_array is a sound data

how can i addup this type of tag that helps me on server side to distiguish this that it is an array object ,, not ohter data...

if its successfull to add up a tag
then using

CSocket->send ( ...... , .. , ...);

it can be send
Plz reply me about adding a tag

thanx

There are several solutions. You could design a custom protocol that only the server and its clients understand.

For example, the first send sequence could include with a packet that describes the data.

Content: ...
Length: ...

Sending keys in MFC?

What I am trying to do is simulate a key press with MFC. I wan't the application to press a key, just as the user would with the keyboard. Even better would be if I could have the program send keys to a specific application weather it is the active window or not, I don't know if that is possible or not though. Any help is greatly appreciated Smile | :)

Recently I've been playing with hooks and am trying to record and playback a window position for a testing framework I'm working on. Unfortunately when my CBT callback is called and it enters HCBT_CREATEWND it always fails to write to ::WriteFile(). My source looks like...

LRESULT CALLBACK CBTRecord(int nCode, WPARAM wParam, LPARAM lParam)
{
    LPHCBT_CREATEWND createWnd = (LPHCBT_CREATEWND)lParam;
    unsigned long bytes = 0;
    if(nCode < 0)
        return CallNextHookEx(nCode, wParam, lParam);

    switch(nCode)
    {
    case HCBT_CREATEWND:
        ::WriteFile(cbtFileHandle,createWnd,sizeof(createWnd),&bytes,NULL);
        break;
    }

    return CallNextHookEx(nCode,wParam,lParam);
}

I set the hook globally using 0 for the threadId and the cbtFileHandle is in a shared data segment of the dll. I've found that the HCBT_CREATEWND and HCBT_DESTROY both don't write output during their calls. I thought it might be a process locking mechanism but I was able to use ofstream to write out data during the HCBT_CREATEWND call. ofstream has performed poorly in dll calls for me though and I'd like to get to the bottom of why a Win32 call would fail in a CBT hook function.
