No.
Your request is so unclear that one can not get the abstraction from your interface design to the MFC-actions to perform.
Sorry, but you need to restate your question.

With some luck, structuring and breaking up the problem for publication is half of the solution. Big Grin | :-D

file sharing tranfer using mfc

hi Im currently working on wince( evc++).
my project includes sharing and tranfering of files between an ebox
and a computer ( currently running wince only). i.e. the tranfer is
between wince to wince rather than desktop to wince.

also i am using MFC to implement my project as im not very comfortable
with EVC++ .

if anyone has implemented any kind of project as described above( using
MFC) and does not have aproblem sharing the source code, please mail
me.

also apart from the file sharing i also have to implement a chat
system. so that different pds/ebox/ can communicate among themselves as
well as the desktop computer/ server running wince.

expecting a reply.....

I haven't worked on EVC++ but as far as development of application is concerned we transferred files from one machine to another in the shared folders of the computers that had read / write privileges.
Use WNetResource structure etc to see how you can have access to the shared resources on the remote machine and then read and write through Sockets or what ever you are comfortable with

Does this solve your problem

Optimization on FileReading in VC++

Hi,

I am working with File reading in VC++. I am reading a log file which has around 1 lakh records. I have to read each record and filter them based on some options and display them on the UI.

The problem that I am facing is that it takes enormous amount of time to read so many records. I am using CStdIOFile for reading. Can any one please help me with some optimization techniques that will speed up my reading process.

Thanks
Madhavi.

It is better you should implement a worker thread for readng and displaying in the UI.

Hi, I think you should put each line of the log file in the CStringArray and lunch a worker thread to parse each item of that array. Good luck!

p.s. it would be nice to have a progress window Smile | :)

You could try overlapped file I/O, with a number of pending file reads simultaineously.

Hi,

In the dialog editor (I use VC 6), the size and positions are shown in DLU. Can I change it to screen pixel uints?

Thank you.

It was not to get the values in run time. I meant to view the values in status bar of the dialog editor.

Yes you can chage the size and position

First of all you have to take the thatspecific window rect.

Use SetWindowPos() function to do this..

I am afraid you have mistaken.

We can see the size and position of selected control in the status bar, when we are in dialog editor. These are in DLU. I need to view them in real pixel scale. I think you got what I meant.

Thank you.

about in UNICODE exe Hook MessageBoxA

i want in UNICODE exe Hook MessageBoxA and add some String, like:
MessageBoxA(NULL, "Hello", "Caption", 0); -> MessageBox(NULL, "Hello-Add", "Caption-Add", 0);

int WINAPI MyMessageBoxA(..lpszText, lpszCaption...)
{
...
strcat(lpszText, "-Add"); // <--- 1.
strcat(lpszCaption, "-Add"); // <--- 1.
MessageBoxA(...);
}

1.strcat and _mbscat, which function i need use?

well if you are hooking MessageBoxA in a UNICODE exe then it won't be called unless you specify MessageBoxA instead of MessageBox.
Anyways i think you can use strcat in MyMessageBoxA if it hooks the non unicode version of MessageBox AKA MessageBoxA

What is the need to hook MessageBoxA here? Simply calling it should do.

_tcscat should do it.

hi All
i am unable to find erase background event in Dialog
based application, ihave read somewhere that it's np
longer supported in vc 6++. Is there any alternative
as i have to make my dialog flicker free

what do you mean you can't find, its right there.

BEGIN_MESSAGE_MAP(CMydialog, CDialog)
	//{{AFX_MSG_MAP(CMydialog)
	....
	ON_WM_ERASEBKGND()
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

then add function to mydialog.h file

BOOL OnEraseBkgnd(CDC* pDC);

and add the body to mydialog.cpp file

BOOL CMydialog::OnEraseBkgnd(CDC* pDC)
{
     return TRUE;//don't erase
}

MFC App needs to call routine from a DLL made using JNI -- Urgent

Hello All,

I've a MFC application from which I've to call a routine from a DLL.
EARLIER, This DLL was getting used by a JAVA application.
But now there is a MFC application instead.
We dont' have to change the DLL code for this in any case.
The export routines have following declaration:

JNIEXPORT void JNICALL Java_gui_config_setManufacturer(JNIEnv *env, jobject obj);

Please let me know how this routine can be called from MFC application.

Thanks in advance!
