Strange problem when not in debugger

[Rinaldo]

Hi,

When I start my program in the debugger, there is no problem, but when not I
get an exception.

It appears in:

private void Upload(string filename, string FTnaam)
{
MessageBox.Show ("in upload.");
FileInfo fileInf = new FileInfo(filena me);
MessageBox.Show ("file: " + filename + " upload: " + FTnaam);

string uri = "ftp://" + F1.FTPserver + FTnaam; // fileInf.Name;
FtpWebRequest reqFTP;
MessageBox.Show ("Uri :" + uri);

// Create FtpWebRequest object from the Uri provided
- reqFTP = (FtpWebRequest) FtpWebRequest.C reate(new Uri("ftp://"
+ F1.FTPserver + FTnaam));
here its going wrong

The bottom line: until you post a concise-but-complete code example that
reliably reproduces the problem, you're unlikely to get an actual answer.

Must I post it here or somewhere else?

to spend time looking at it is much smaller than if it were more concise.
If you are absolutely sure that that is the smallest sample you can
provide, you'll have to accept that severe restriction of your audience,
possibly to the extent that you won't get an answer at all.

Re: Strange problem when not in debugger

Ihope that it was all. If missing something, I hear it. The program's that I
make are free for charge. It is a hobby of my. In the past, 20 years ago, I
programmed C, but gorget all about it.

Are you serious? The single post to which I replied, in which I pointed
out that the sample was FAR too large to be useful, was not actually the
entire sample?

You _really_ need to pare your code example down for anyone to look at
it. I know I'm not going to sift through all of that just to try to find
the answer to the one question. I'd be surprised if anyone else would
either.

I realize that doing so may be challenging, but it's really the only way,
at least if you're asking the question here. This is a volunteer effort,
and for people who are paid to solve your problems, the work involved in
taking your entire program as the "sample" is far too great a barrier. If
you're not willing to put the effort in yourself to come up with a
reasonable, concise example, you should consider paid support from
Microsoft. It'll cost you money, but you'll have the luxury of being able
to send them your entire application and have them help you with it.

Re: Strange problem when not in debugger

How small it must be? I thought you mean the whole code. The first message
is with the code wich goes wrong. Pfff I read the message with a dictionary
with me.

Here it goes wrong in the code:

private void Upload(string filename, string FTnaam)
{
// MessageBox.Show ("in upload.");
FileInfo fileInf = new FileInfo(filena me);
// MessageBox.Show ("file: " + filename + " upload: "
+ FTnaam);

string uri = "ftp://" + F1.FTPserver + "/"; //
ftp://ftp.lampiesoft.nl goes also wrong as uri
FtpWebRequest reqFTP;
MessageBox.Show ("Uri :" + uri);

// Create FtpWebRequest object from the Uri provided

reqFTP = (FtpWebRequest) FtpWebRequest.C reate(new Uri(uri));
//"ftp://" + F1.FTPserver + "/" + FTnaam));

with the call to new Uri(uri)

I thought the whole code mabe someone can reproduce it.

I think some english/american sentences I do not understand correctly, I try
it but there are nu C# groups in dutch where I can ask.

Sorry for the unconvinience.

It must be no larger than the absolute minimum required to reproduce the
problem. It must be no smaller than the minimum amount of code that can
be compiled without adding anything.

The original code you posted isn't complete (nor the latest, which is the
same). It uses variables that aren't declared and for which we have no
way of knowing their values. The "whole code" you posted isn't even close
to being concise. It is literally the whole code, which isn't what I
asked for. "Complete" simply means that I don't have to add anything. It
doesn't mean that I need every line of code you've written.

Here's a concise-but-complete code example that _doesn't_ reproduce the
problem:

using System;
using System.Collecti ons.Generic;
using System.Text;

namespace TestCreateUri
{
class Program
{
static void Main(string[] args)
{
Uri uri = new Uri("ftp://ftp.lampiesoft. nl");

Console.WriteLi ne("Uri: " + uri.ToString()) ;
Console.ReadLin e();
}
}
}

You claimed that there's a problem creating the Uri. You create the Uri
using a string, so it should be possible to post code that simply passes
some string literal to the constructor and throws the exception.

In my example, I used the only full URL you offered as my test string. It
runs just fine, so obviously that string isn't the one throwing the
exception.

Hopefully, you can provide something similar to the above but with a
string that does throw an exception. Then someone here (maybe even me)
can explain why the string's not valid.

It's _possible_ that you may need to provide more elaborate code. In that
case, that would mean that there's something other than just the string
causing the problem. That the string itself is normally valid, but that
something else in your code is somehow causing it to be invalid.
Hopefully that's won't be the case; if it is, it is likely to take a lot
more effort on your part to come up with an example. However, if it is
the case, then the only way for you to get help is to provide that
example. No one here gets paid enough to sift through your complete
application code to try to find the magic combination that causes the
error.

So, as a first step: try to provide the very simplest example. What's the
string being passed to the constructor when the exception is thrown? Does
passing that string to the constructor cause the exception even in the
context of a program as simple as what I showed above? If so, write a
version of the code above using that string, so that we can see what the
actual string is.

If not, then you need to figure out how to make a program that contains
the very minimum amount of code that will still reproduce the problem.
The most direct way to do that is to create a copy of your existing
project and start removing things until the problem goes away. Start with
the things that seem the least necessary.

As I said, the exercise itself may lead you to the problem and you won't
need anyone else to point it out. But at the very least, when you're done
you'll have a nice, simple example that you can post here.

Re: Strange problem when not in debugger

Thank you Pete for explanation. I now know the problem. Anyway anyhow VS
doesn't clean up the bin directory or whatsoever.
I had deleted the bin folder and try again. Someway somehow it worked again
(the program) This was pure luck I did it because I had enough of it.
I now understand that a small amount of code posted here must be enough for
example.

I hope that someone can make use of my (lucky) deletion for someone with the
same error, however I think it is not happend very much.
I shal remember the things you told me.

Again, thanks for the support, because it is hard to seek an error in
someone els its code.
