Obviously I disagree.
1.
Yes, I happen to know for a long time what base64 means (something similar was used by Digital Equipment 30 years ago in their radix50 encoding they used to stuff three characters in a 16-bit word). However there is no need for such "intrinsic knowledge" to realize the approach is inappropriate. All it takes is reading up on the classes/methods used.
This is the very first line MSDN[^] offers about Convert.FromBase64String:
Converts the specified String, which encodes binary data as base 64 digits, to an equivalent 8-bit unsigned integer array.
I don't think of digits when a Word document has to be handled somehow. Not in base 10, not in hex, and not in a binary encoding of some kind.
When reading on, the same MSDN page also offers a good example, with encoding and decoding code, and encoded/decoded data. How it would fit the job at hand is a mystery to me, and I would hope to anyone who has looked at that page.
2.
I did not intend any demeaning tone, and frankly I don't see one. What I do here is providing information, advice, and guidelines. A universal guideline is this: read up on the class or method you are considering but are not familiar with.

Well, this is what I take objection to:
"That is completely wrong. Do you have any idea what Base64 is?"
And after a completely dignified and calm response (which I wouldn't have afforded you):
"No. You are not using it in the wrong way. It is wrong for you to use base64 at all."
I don't know about you, but where I'm from that's very belittling and seems like someone trying to assert to everyone just how clever and knowledgeable they are. Apologies if that was not your intention, but it seems very much that way to me.
Regardless, why not point him to the documentation? Not everything is "elementary knowledge", and that includes the labyrinth of MSDN. Also, Google is not very helpful if you don't know what you're after.
If you are so frustrated with people not providing enough information for you to correctly answer their question, better you not reply at all then make them feel stupid. I suggest you read the sticky post "HOW TO ANSWER A QUESTION" (although, given your knowledge of systems 30+ years old, I should think you would know how to answer a question):
"If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome."
I believe that includes sideline insults, like yours - while not directly calling him an idiot you might as well have.

And yet, here you are effectively calling Luc an idiot. Ironic, isn't it? 
For your information, Luc is one of the most helpful people in this forum and certainly one of the most patient. Certainly, his patience to idiot threshold is far higher than mine. I suggest that you stop being quite so anal, and looking for offence where none was intended. Perhaps when you have made even 1/50th of the contribution to the site that Luc has, you might be better qualified to comment on his answering style.

I thank you for your advice, but the number of answers someone has posted on an arbitrary forum has no bearing on their ability to be helpful. The fact that you, also a prolific poster, called the OP an idiot makes me doubt even more the validity of the equation of contribution to helpfulness. All I'm saying is be helpful rather than treat him like a fool, something I've seen Luc do on more than one occasion, so I'm guessing it's not just that he's had a bad day.
I've had the joy of working for programmers of many years' experience who took delight, it seemed, in making me feel like an invalid when I didn't know, or was unaware of, some dark corner of the world of software engineering - I know how it feels. It's not a good feeling.
I will admit I did get a bit hot under the collar, and I apologise for this - I've just seen this so many times (especially considering my whopping 3 years of commercial experience) that I have trouble letting it lie.

Hi Nick,
I really appreciate your feedback. I have to agree with you, I have no doubt in thinking Luc is probably one of the most knowledgeable in these forums but from my experience he has been very unhelpful and I did take his feedback as being a little rude.
I refreshed on Base64 and found the following very helpful:
http://www.aardwulf.com/tutor/base64/base64.pdf
Here is an explanation of the process I’m trying to achieve…
I’m using a class library named SmtPop to allow the retrieval of email from a Pop3 server.
1. After the emails are retrieved from the server I check if they have attachments. attach is of type MimeAttachment
2. If an email has an attachment then the text within the attachment is accessed through attach.Body.
3. I then want to create a file to save the email attachment text into and give the file a different name to its original.
The only reason I’m converting the body of the attachment to a Byte array using Convert.FromBase64String, is because MemoryStream takes in a byte array as its first parameter in order to create a memory stream that can then be written to the file. FromBase64String is the only convert method that I know of that returns a Byte array.
Maybe there is an alternative way to the MemoryStream that doesn’t involve converting the attachment string to a Byte array?
Let me know if any of this isn’t clear.
Thanks again,
Mel

I'm going to read up on the StreamWriter now.
Thanks.

I found out that with MIMEAttachments, plain text word documents have "base64" as their ContentTransferEncoding value and HTML formatted word documents have "quoted-printable" as their ContentTransferEncoding value.
Does anyone know or can you refer me to a site that explains how to download quoted-printable formatted emails?
Thank you,
Mel

I have a generic event handler:
public delegate void EventHandler<TEventArgs>(object sender, TEventArgs e);
public class EventArgs_Generic<T> : EventArgs
{
private T _TargetObject;
public T TargetObject
{
get { return _TargetObject; }
}
public EventArgs_Generic(T Target)
{
_TargetObject = Target;
}
}
How do I list this in an interface? Something like...
event EventHandler<T> ....
Thanks
Everything makes sense in someone's mind

You can do this:
public interface IFoo<T>
{
event EventHandler<T> Bar;
}
Or you can just make the generic type concrete in the interface:
public interface IFoo
{
event EventHandler<int> Bar;
}
Depending upon your circumstances.

Say, I have
DataGridviewCheckBoxCell cell object. I can select/deselect it by doing
cell.Value = true /
cell.Value = false . This works until user manually selects/deselects some checkbox - after that this checkbox stops changing after assigning a value. What could be the reason for that?
|

|

Assuming you've bound the grid to a datasource, you have to modify the datasource, not the cell values.

In SQL Server, I was doing this in the stored procedure:
param_record_id int OUTPUT
then I :

how can id o the same in mySQL stored procedure?

Hi,
I have an appointment software using C# WinForm and I want to send alerts (SMS & Emails) through SMS gateways and email to the customers..
I want to know what's best...
1. Send the alert directly from the PC? this will require an internet connection on the PC.
or:
2. Send the alerts to the database on the server and make it in queue? this will not require internet connection to be enabled on every PC.
what do you think?

This is entirely up to your clients requirements. Personally, I'd go for a more centralized solution, but have no idea what your specs are, the design of the application, what the load is going to be, what the clients restrictions are, ... In other words, you should be asking your client this question, not us.

my client doesn't talk IT
I have dell server and dell clients
it's a medical software for a clinic with let's say 100 appointments per day
My backend is MySQL and I am using C#.
if you were given this what you will do? will send it from the PC or queue it on the server?

I alreay told you what to do. Interviewing the client and gathering detailed requirements is what I'd be doing. Guessing at what the client wants will only get you fired, or not paid when the job is "complete".
I also already told you what my preference would be, but then, I'm not the one coding the app and I'm not the one who's going to pay for it.
