While the above suggestions are all perfectly valid, you may want to consider calling Reflector programmatically with parameters for each version of the .Net Framework. This will give you the option of seeing what your options are for a variety of deployment scenarios.
Once you do that, you can then use Reflector to dynamically decompile System.Net.Mail into usable code which you can then modify to suit your needs.
One such modification you'll want to make sure you do before proceeding any further would be to create a hash structure so that you can easily ascertain whether or not you've already sent an email. Naturally, this hash structure should be built to serialize to the hard disk when memory consumption is too high. This will reduce your overall network overhead and improve your performance.
Trust me, your manager will thank you just for following those 3 simple steps.

What your a masochist. You've been here a while and asked some sensible questions in the C# forum and suddenly you do a Don Juan and tilt a programming question at the Lounge, consider yourself SMACKED, now go back to the C# forum and ask this question.
Ahhh I enjoyed that, we don't get enough of these misplaced questions any more.

Ok, here is the problem that drives me nuts.
I have a datagrid with various data.The first column is the date of the record and it's a string.
The following code gives the error
tempor=Month(dgv1(0, counter).Value.ToString)
On my PC the code works flawlessly.But when i give the application to someone else for BETA testing, it produces the error.
Does it make sense to you ?
I also tried all the variation to the code, i could think of, like using cdate and cstr functions, changing the type of the tempor variable to date, string, using the .string or not at the ende of the code, to no avail

Not exactly; your title says you are converting from the string "18/8/2009", but your code is converting something ToString(). Can you clarify a bit more what is in dgv1(0,counter)?

The field of the datagrid contains "18/8/2009".This is a string.
I am trying to get the month part of this date.
On my computer whatever i try WORKS.
On the other PC whatever i have tried, DOES NOT.
Even if i don't put the .string, DOES NOT work on the BETA tester.
To make it simple.How do i get the month part of the above field to use as an index in an array ?

|
|
|
Τhe problem seems to be the regional setting of the other pc, which are different than mine.If they are change to the same as mine, it works
Hmmmmm
|
|
|
|
|
you could split the string ( string.Split() ) and then take the second index of a string array, then you have the number of the month, maybe you could work with that?
Here we rest... So why not make the best of it?

Not a good answer, study DateTime structure.
|
|
|
|

it seems you don't have a clue.
the only thing that could go wrong in tempor=Month(dgv1(0, counter).Value.ToString) is a NullReferenceException due to dgv1 or Value being null.
if there is a problem, it is bound to be in a different line. Look at the entire exception.ToString() output, tell your IDE to show line numbers, and get the line at fault.
Most likely it is about date formatting. The first thing about it is you have to decide whether you want a user-selected format (through Regional Settings), or a fixed format (specified explicitly in your conversions, see the Parse/TryParse method overloads that take explicit format info).

Your problem is that you are storing your dates as strings. THIS IS WRONG AND VERY STUPID. This is error number 1 when a newbie starts working with dates. You should IMMEDIATELY go back and change your date storeage and manipulation from string to datetime.
Dates are subject to the computers cultureinfo, this means if the user has not changed the culture of the computer from the default american format (stupid friggin mm/dd/yyyy yank format) your 18 is being read as a MONTH, If it was a datetime format you would not have this problem.

Although i am not exactly newbie at programming, i admit i am relatively new to .net framework thing.
As i said on my second post, the problem was indeed the regional settings.The user had set them to American, and so it was reading 18 as Month, thus the error.
The reason i didn't use datetime in the field, is because the data are stored in a MS ACCESS database, and it was giving all sorts of problems trying to use the field.So many different bugs i don't even remember.
So i made them strings.
However i might give it one more shot to see what happens.

I would concur with the comments from Luc & Mycroft. Do not store dates and times as strings, it just leads to exactly this sort of problem. A DateTime value is universal and can be displayed in whatever format is required, and in many cases converted to a non-Gregorian calendar.

I would strongly recommend trying. You will almost certainly run into malformed dates already in the field which will produce error but then you will be fixing your data

I have a c# application that uses the Office PIAs to enable the application to export data to an Excel file. This works great on my development machine and other desktop machines.
When I run the application on a Terminal Server (which has Office available) I get a SecurityException and the application crashes. The debugger recommends I read up on security permissions and distributing office apps (helpfully providing a link). Going through this documentation, it seems to mostly pertain to writing add-ins for the Office suite instead of using their functionality.
Is there a tutorial that I can follow so I can preserve this functionality or at the very least disable the function and prevent the crash? Due to deployment issues I'd like to avoid modifying the .NET system policies if possible.

I had a command that inserted two tables, both using identity columns as primary keys. The identity value obtained from the first insert was used in inserting the second table, and two output parameters on the command should reflect the value of the two primary keys after insertion.
The command text was hence something like
INSERT A VALUES (@p1, @p2);
SET @A_ID = SCOPE_IDENTITY();
INSERT B VALUES (@p3, @p4, @A_ID);
SET @B_ID = SCOPE_IDENTITY();
I had added sql parameters for the identity values, and set the parameter direction to Output. After executing the command, I found that cmd.Parameters["@B_ID"].Value had been correctly set, but the @A_ID parameter invariably had the value zero.
Looking at the inserted data however what was really made me wonder what was going on here. The B record contained the correct foreign key, demonstrating that @A_ID had indeed been assigned correctly!
After hours of headscratching I stumbled upon the explanation: The code creating the command first added a parameter @A_ID as an input parameter, then added another parameter also named "@A_ID" as an output parameter. I don't know how exactly the provider communicates the variable declarations to SQL Server, but it appears that the second declaration simply overwrote (redeclared) the already-defined @A_ID. Then, when my code attempted to get the value, the SqlParameterCollection probably did a linear search returning the first parameter with a matching name, which of course was the input parameter.
While not checking for duplicate declarations may save a few microseconds, it would have been nice if by default such validation was performed and could be disabled instead via the ado.net configuration (for production). I certainly lost a lot of time, and probably some hair, before I found out. If it sounds like I was just being slow, let me add it wasn't that easy to check everything when the command had about 100 parameters.

Good find bro. I would surely try out this and see. If it really happens, it wouldnt be good.

Hi,
This is what I want to do.
- Want to display an HTML page in a browser, kioskmode.
- Depending on information I get through a webService, I need to change the URL.
Any suggestions/technology how to achieve this ?
Additionally, how can a browser render its HTML 'in the background', and when ready, swap the 'old content' with the newly 'rendered' content.
So, in the kioskmode, we avoid the 'building' being displayed to the viewer. Any idea ?
Thanks in advance !
Dirk

WinForms has a WebBrowser control[^] that you can use to display a web page on your form.
You could have 2 of the controls and keep one hidden, then do the reloading on the hidden one and switch them around when the rendering is complete.
As your app is just a win forms app you should be able to set it up as the endpoint for a WCF (or webservices or whatever) service and when it receives a message, you can load the appropriate URL in your browser controls.
