Be a man, and use threads instead. Timers are for people that are closet VB programmers.

I'm just curious: How would you achieve what I'm after with a separate thread? I like the idea but they're scary 
Would I just use Thread.Sleep in that thread instead of a timer?
Thanks!

Using threads requires more code, but they're a lot more flexible than timers. That, and the fact that Toimer events in Windows are the lowest priority events, and on a busy system, they're not guaranteed to be fired. That means there's a certain lack of reliability, and that's a "Bad Thing" (TM).
Before committing to using threads in a production app, you should create some test apps and get used to the idea of them. There are a lot of good articles reagarding the use of multithreading here on CodeProject.

Put a try/catch block around your code, and run it under the debugger so you can see why you're not getting a response.

I try to execute a command on my MSACCESS database and I get the exception above.
The query seems OK and I cant find any problems with it, I don't think there is a problem with my SQL code.
Here is my code:
com.CommandText = "SELECT activities.*,company.CompanyName,contact.ContactName " +
"FROM company,activities,contact,company_type,activity_type " +
"WHERE (activityTypeID.CompanyID=company.CompanyID AND " +
"activities.ContactID=contact.ContactID AND " +
"activity_type.TypeID = activities.ActivityTypeID) " +
"AND " +
"(CompanyName=@CompanyName OR @CompanyName='') AND " +
"(contact.ContactID=@ContactID OR @ContactID=0) AND " +
"(activities.ActivityTypeID=@ActivityTypeID OR @ActivityTypeID=0) AND " +
"(company.CompanyTypeID=@CompanyTypeID OR @CompanyTypeID=0) AND " +
"(StartDate>=@StartDate AND StartDate<=@EndDate) AND " +
"(Reminder=@Reminder OR @Reminder=false)";
com.Parameters.Add(new OleDbParameter("@CompanyName", companyName));
com.Parameters.Add(new OleDbParameter("@ContactID", contactID));
com.Parameters.Add(new OleDbParameter("@ActivityTypeID", activityTypeID));
com.Parameters.Add(new OleDbParameter("@CompanyTypeID", companyTypeID));
com.Parameters.Add("@StartDate", OleDbType.DBDate).Value = start;
com.Parameters.Add("@EndDate", OleDbType.DBDate).Value = end;
com.Parameters.Add(new OleDbParameter("@Reminder", reminder));
DataTable dtAct = new DataTable();
OleDbDataAdapter adapter = new OleDbDataAdapter(com);
con.Open();
adapter.Fill(dtAct);
con.Close();

Haven't really used OleDb .Net classes but some of the providers are not able to bind values multiple times by name. Since you have the same parameter multiple times you could try using a unique parameter for each bind variable. For example:
... "(CompanyName1=@CompanyName OR @CompanyName2='') AND " + ...
...
com.Parameters.Add(new OleDbParameter("@CompanyName1", companyName));
com.Parameters.Add(new OleDbParameter("@CompanyName2", companyName));
...

It doesn't seem to be the problem, because I did the same with other queries
|
|

Not sure if any of these are wrong, however I notice some inconsistencies:
1. two parameters were added without an explicit constructor (StartDate, EndDate)
2. some field names don't have a table qualification in the WHERE clause (CompanyName, StartDate, Reminder);
3. you seem to be joining tables without using a JOIN keyword?
From the error message, I'd try #1 first.

Contrast this line (which, im guessing, checks equality or parameter not provided)
benams wrote: "(activities.ActivityTypeID=@ActivityTypeID OR @ActivityTypeID=0) AND " +
with this line:
benams wrote: "(Reminder=@Reminder OR @Reminder=false)";
=false does not work in SQL, change it to
@Reminder=0 like all the others.

You can't read utf8 unless it is in fact stored as unicode (or perhaps packed into another character set.)
If your database has something like nvarchar(2000) for the data type then it is unicode presuming that the person that put the data into it did it correctly.

Hi everybody,
I didn't know where to place this topic, so if mods consider that it should be elsewhere... no problem .
I'm developing a desktop application in C#. The first dialog it is a login form with user and password editboxes. I'd like to authenticate against a web service (using a database). Also, I'd like the connection was secure using SSL/TLS or whatever. I'm not sure how to do this, or if there is a better way to do remote authentication. I've been reading about WS-Security, SOAP... But before doing something, I wanted to ask here.
Thank you.
Regards

This implies the secondary mouse button - and that is used for CONTEXT menus not sub menus.

context menus can be hierarchical, Visual Studio has lots of examples.

Sure but the OP is talking about right clicking on an outlook menu bar, you do that till the cows come home and you will not get a sub menu.

You're right, except maybe about the cows, I don't know. I have been told they come home all by themselves, eager to get milked.

The menu when you click the right mouse button is called a context menu, not a sub menu which is likely why you didn't find it on the msdn site.
This MSDN Link may be of help. I understand that the source is in vb, but it shows how to do this.
As well, this site appears to have some really good tutorials for add-ins. You may find some context menu stuff in there too.
I wasn't, now I am, then I won't be anymore.
