The first thing I would do is print out an .ini file on your system that fits on a single sheet of paper (for me this was win.ini). Then on a separate sheet of paper, write out what the resulting XML format should look like. Some things you should notice:

Each section in the .ini file should relate to a set of same-named tags in the XML file. For example, if the .ini file had a section named [Mail], then you should expect to have <Mail></Mail> tags in the XML file.

Each key in a given section of the .ini file should relate to a set of same-named tags within the aforementioned tags. For example, if the .ini file had a key named MAPIXVER with a value of 1.0.0.1 in the [Mail] section, then you should expect to have <MAPIXVER>1.0.0.1</MAPIXVER> in the XML file in between the <Mail></Mail> tags.

Make sense?

Hello,

You should choose the method you want depending on your needs. If you want really fast data transfer, you could use UDP, but the data might not arrive completely. If you need the data exact as you send it, TCP could be of some help. It is a little bit slower, but the data arrives just like you send it.

You could also use some form of middleware (CORBA, RMI, ...) but this is more slow than raw socket programming. It is more easy in most cases though.

You'll only learn to make the best choice by experience...

Thanks Blog,

Its very usefull information for me. but can you differentiate socket connection vs pipe,window messageing , RPC. so that i better understand
which is sutable for my applicaion.
I want to develop two application one store some information in data structure and other retrive and delete that information.
I don't want to use database. i want fast processing in it.
can you suggest me which is better.

Hello,

First, my name is not Blog, it's Bob.. Smile | :)

So you want to process your data fast. What has to be fast? The connection so that your data is transferred quickly? Do you want your application to process the data fast? How did you define "fast"? By this I mean, by what numbers is your application considered fast...

One other thing, where do you store the information. Do you store it in a file or do you keep it in RAM? Does the retrieval app needs to extract the information by itself or does the storing app push the data to the other...

I think that you need to do some more research on what you really want. After you do this, the way you'll need to communicate will become clear. One advice, don't bother too much with performance now, implement one solution and when it isn't fast enough, you can always do better later!

Kind regards,
Bob

second application monitoring agent who is idle for
handling that call. as soon as agent free it retrive call information
which is stored by first application in linklist and route that to agent. and
delete that information from linklist.

i want to store information which is shared by both application. i read about file mapping but i don't want to use file or database.

please help me bob.

Hello,

So if your applications run on the same machine, this solution will work:
Create a DLL which can be used to store and retrieve the information. The first appication stores information and sets a signal or something so that the second application can retrieve the information.

If your applications run on different machines, you should use a middleware of some sort. You can try RMI, DCOM, CORBA, etc..

Hope this helps Smile | :)

Then you must be aware of things like:

RPC, perhaps.

I advocate using pipes. They can be used for processes on the same machine and on different machines. There is lots of information available about them too. Look for "named pipes."

Get the listing of the files present in the specified directory.

HI friends,

I just want to share this code with you people as when I was in need I could not find it anywhere.

hope it may help you some time.

cheers !

// This is a part of code to get the listing of all files in the

// Dont forget to add the following line

#include <windows.h>

{
WIN32_FIND_DATA FindFileData;
HANDLE hFind;

// Path of the file to find. It can contain wild card characters(* or ? )also
char folderName[] = "e:\\someFolderName\\*.*";

hFind = FindFirstFile(folderName, &FindFileData);

if (hFind == INVALID_HANDLE_VALUE)
{

}
else

That makes me wonder where it was that you were looking. Your code snippet is one of the most common pieces found on the Net.

vikas amin's post is good. If you're really new, you may need this as well. Each menu item has a certain ID associated with it. You'll see that when you right-click on that item and choose properties. Now in the Wizard Bar, choose the appropriate class in the far left drop down list. Then, in the next drop down list you'll see a list of IDs. The ID of your desired menu item should be there. Select it and press the Wizard Bar action button, or just double click the menu item ID, and a function will be created for you (e.g. OnFileNew()). That's where you want to put your Dialog initialization and call.

It seems that the textfile you're reading is UNICODE/UTF-8. You will have to take that into account, or reencode the file into some codepage. Windows 1250-something has å, ä, ö. I think. Unsure | :~

ISO-8859-1 (and -15) has them too.

Hello (Hej.)

My guess is that you read a text file, written in another charset than ANSI, probably a PC-8 (DOS) charset, CP 437 or 850.

Use the Windows func OemToAnsi to convert the text lines from the file to ANSI. And from there, do another conversion to Unicode if you whish.

You might also to considder the opposite character conversion func, AnsiToOem.

Use them as they are, or use them as member functions in a CString.

Hi,
I am developing hook application, which will create a file whenever the user do any SAVE_AS operations on any IDE (notepad, visualstudio...).
I can be able to get the save_as name (new name) for all applications EXCEPT Microsoft office packages(microsoft word, excel, frontpage...).
How could we get the save_as name when user do any save_as on this (microsoft word, excel...).
Please any help.

Be simple and Be sample.
