WM_APP begins a range of messages for private use by an application to do whatever it likes.

Nothing, unless you use a private message to help with the work.

is the code i got from msdn for parsing mails
i have doubts in it like..
in the readnextmsg function what is ..c:\\pst\\myprofile.pro???
what shud i use in my program instead of that..and in the findnext function..whats OL??what are the parameters to be passed to the functions...so that i can autmate the process of receiving mails in my inbox!
thank u

whats OL??
It's 0L, not OL (zero, not uppercase o). It's simply 0, as a long.
I haven't used MAPI before, so I can't help you with the MAPI stuff.

Hi all.
Please tell me how to read a word document from C, using simple fopen statement.
Please.
|
|
|
|
|
Hi,
It simple open doc file, call fopen(...) and next read him.
Absolutely other task that you will do with it after reading
Vitali

|

No the problem is , if i do a fopen, it reads from start. I want only the text content, no the header.
how to do this.
|
|
|
|
|
As I know doc is not open format.
To read it using low-level functions
you should know this closed format.
Vitali

|

|

It would not be easy. A Word document is an OLE compound file. You'd be much better off using StgOpenStorage() and then using the IStorage interface. I'm not an expert on this, but you should be able to find examples around about using IStorage.
Hope this helps,

Hello guy,
So, this is true, but question is about fopen.
I alsow want know how?
|
|
|
|
|
Sorry, I don't know about this. You'll have to try and find the format of an OLE Compound file. I doubt anyone here would know it - I think almost everyone here would do it using StgOpenStorage().
Are you programming for Windows, or Linux or another O/S?

Actually, I'd be inclined to use Word Automation. If that, in turn, is handled by StgOpenStorage() and/or IStorage, I'm not sure.

I was meaning, "assuming they wanted to read the file directly" . Word Automation is obviously a much nicer way to do it
FYI, I think I remember seeing the Word does use IStorage internally

Word is a closed format that isn't documented. Reading it via fopen will only give you a lot of binary data and not the text of the document.
What exactly do you want to do with the data once read? You may be better looking at using the WORD COM object model to load the document and do your work on it.
Have a look on MSDN for KB196776.

I would have said that, but there's a number of reasons you'd want to use the file directly. One I came across is that you can not get access to image data via the COM object model. I ran into this while trying to get PowerPoint slide information, and it has caused me a lot of heartache since  .

Hi !!
Here is what I'd like to do in C++ : (I don't know if it's possible or not)
I have several functions in a class. I want to call one of them according to a given string representing the name of the function to be called. It looks to me that the only possible way to do it is to manually compare the given string with each existing function and call the good one, but I think it would me much better to have it done automatically, without having to add a comparison if a new function is added.
I'd like to have something like :
MyObject->callThisFunction("processArray");
which would result in calling the processArray() function.
Any help or suggestion will be greatly appreciated !

Use a map and add a macro to add new functions to the map. Then add code to execute the function in the map if it is found.
John

Hi,
thanks for your answer, but I'm not sure to know what is a map, and how I could use macro to add new functions to the map.
Could you be more specific ?
Thanks !
Jerome

A map will allow you to map the string names to the function pointers. This is STL and not a beginner subject. It's too early in the morning (05:33) for me to go into much depth now I'll see if I can expand later after I catch some more  ...

Hi,
As I right understand you want create somthing
similar as command processor - take text input
and execute it commands.
Do do this simplest way is create association
between C++ functions(class members) and array( or map )
and function that should find 'assoc' in the array by
be text and call them.
Hope this help.

Do you ultimatly want to make your application scriptable?
There are a few articles on how to do that on CP and they also explain what to do to let the scripts call methods of your applications objects.
Who is 'General Failure'? And why is he reading my harddisk?!?

Could you point out such articles ? I tried to search CodePorject for them (with keywords like 'scriptable') but couldn't find any !
Thanks !
