Hmmm, guess I used too much text then? 
Still hope someone can help me out here. In the mean time I've made the app work without threads so I can continue working, but I like my GUI responsive!

Hi,
I have +20 comboboxes in my windows app. and thought its best to have the code in a seperate class and than call that class and pass the parameters using a constructor...
With this one function I hope to fill every combo box that i have in my application from a database table.
But not sure how to get started with it.
thanks
Wouter

First I'd say from a UI perspective 20+ comboboxes on a screen is probably not the best design. Think about breaking them up with tabs, or sub forms if it makes sense.
What you can do is iterate through the controls collection to find each combobox and set the properties accordingly. Or you could set DataBinding between the comboboxes and your datatable

I have 14 forms and 20 combo's in total, So each form has max 2 comboboxes on it.

More reasonable then. DataBinding, IMO, would be the best approach in this case.

Mark,
Thanks, the answer was indeed easyer than the question, solved the problem !
In class "cls_role.cs":
public DataTable GetRols()
{
DataTable DT = new DataTable();
string Query = "GetRols";
DT = _dbHelper.ExecuteDataTable(Query);
return DT;
}
In Winform:
private void GetRols()
{
Cls_Role Role = new Cls_Role();
cmbRole.DataSource = Role.GetRols();
cmbRole.DisplayMember = "Role_Name";
cmbRole.ValueMember = "Role_ID";
}
I was thinking to complex

Well, have you looked at what you are actually passing to the SQL? datetme.now.tostring() gives you the date AND time down to seconds, so unless your database date EXACTLY matches the system date and time nothing will be returned.
2 minutes in debug would have shown you that.

Don't pass it as a string; use a parameter.

I'm using a PropertyGrid in C# to display ConfigurationElements. I have an implementation of a ExpandableObjectConverter TypeConverter to display the sub-elements (with descriptions) in the property grid.
E.g.
Item 1
First sub-item
Item 1 ID
Second sub-item
x
Item 2
First sub-item
Item 2 ID
Second sub-item
x
...
I want to display the sub-elements in a specific order - not alphabetically (e.g. The ID before the other sub-elements).
Could anyone please tell me how to specify the ordering? (I've Googled it, looked at CodeProject articles, looked on MSDN - where I (momentarily) thought I'd found a solution using SortProperties - which turns out not to be overridable.)
Any ideas would be much appreciated.
P.S. I tried posting this in the Quick Answers - but I can't see my post (so please don't flame me for cross-posting if you can see it in both places).

Thanks Dave, but if I view all questions under QA (All Questions | Latest) I don't see it. Am I being a dumbass?

Hola!
I want to use a regexp, and I've partly came up with it, but I cannot get the last bit to work. The regular expression I'm currently using looks like this:
(\d{3}\s\d{2})(\s[A-Z])|(\d{5})(\s[A-Z])
And I want to use it extracting a Swedish zip code which looks as follows:
111 11 City
or
11111 City
The reason I have the letter in the Regexp is that I don't want any other number sequence.
So the question is:
Is there a way to just get the numbers from my regexp, some kind of split or something like that?
All the best
Simon

You already have the number part wrapped in parenthesis - which implies a capture group - so you already have it.
I suggest you download expresso - a very helpful tool for debugging regex - google will be your friend in finding it.
Having tested your regex using expresso. I can give you 2 pointers:
1) Name your capture for numbers - it makes it alot easier to extract just the numbers:
(?<numbers>\d{3}\s\d{2})(\s[A-Z])|(?<numbers>\d{5})(\s[A-Z])
2) You're only testing for upper case chars - so your regexp only captures as far as the 'C' in city. Fix this like so:
(?<numbers>\d{3}\s\d{2})(\s[A-Z])|(?<numbers>\d{5})(\s[A-Za-z])

Cheers for your reply J4amieC!
However it doesn't work, Visual Studio doesn't seem to recognize the use of ?<numbers> 
I know the part of the letter, but that was just there to distinguish the zip code from any other kind of row of numbers. But if I manage to extract the actual zip code by using numbers, then I could do the same with the letters (City) I presume, so that would be great...If I only could get Visual Studio to understand what I'm trying to achieve 
Another question as well...My Visual Studio doesn't want to work with me on a different point too. It won't accept the use of ^ (like in ^\d{2,5}).
I'm using Visual Studio 2005 by the way,,,maybe that's why this is giving me a hazzle?
All the best
Simon

Why not a simple: \d\d\d\s?\d\d ?

Hello PIEBALDconsult
I tried using your example, but the thing I want to avoid happened. I just want to get 123 45 or 12345 from a zip code, but \d\d\d\s\d\d and \d\d\d\d\d returns any line of numbers 1234567890. I know it's easy to solve with ^ in the start, but since my Visual Studio wont let me use ^ I have to go the long way around,,,if there's a long way around, I'll probably end up on dark forest paths and eventually plumb into a deep dark hole.
Cheers for the suggestion anyways

Give this regex a try:
(^|\D+)(?<postalCode>\d{3}\s?\d{2})\s(?<city>[A-Za-z]+)
The first group checks for the beginning of the line or a non-digit character. This should prevent the regex from picking up lines with more than 5 digits. The "postalCode" group will have your Swedish zip code and "city" will have the city name.
