ms access 2010 - Adding / Subtracting Two Fields in Query Criteria -

-

I have a table that contains suburbs and their geocodes.

I have a query that selects a suburb from the form, together with +0.5 and -0.5 long and all other suburbs within latitude.

Criteria in the query, respectively for Long and Wide Area;

Between [forms]! [Long] -0.5 and [form]! [FMFIMMetting Locations]! [Long] +0.5

middle [form]! [FMFIMAttinging Leases]! [Late] -0.5 and [form]! [FrmFindMeetingLocations]! [Lot] +0.5

It works perfectly. What I am trying to do, statically changes the '0.5' in the context of the combo box on the form (by giving the option of 0.01, 0.05, 0.5 etc.) I have tried below and various other combinations, etc., but it does not seem to work.

] [frmFindMeetingLocations]! [Late] - [form]! [FrmFindMeetingLocations] [cmbSubDistance] and [form]! [FrmFindMeetingLocations]! [Late] + [form]! [FrmFindMeetingLocations]! [CmbSubDistance] to

I put a text box and refers combo, and value have been added so that way I have two references that seem to recover and I am decreasing, can something happen with that?

On another note, I am clearly using a simple method of finding nearby suburbs. I know that latitude is quite stable for the distance, but varies for a long time - this is only for Victoria Australia, can there be any harm to do so?

It was fixed! All this came down to fill the second statement (which refers to the distance - '0.5') with the val function Done. I'm also not sure why this work is complete, but it does.

so now looks My SQL; 

  SELECT tblStatePostCodeLongLat.Suburb, tblStatePostCodeLongLat. StateCode, tblStatePostCodeLongLat.Long, TblStatePostCodeLongLat.Lat, tblStatePostCodeLongLat.Accuracy from tblStatePostCodeLongLatWhere ((tblStatePostCodeLongLat.StateCode) = "VIC") and ((tblStatePostCodeLongLat.Long) ([form]! [FrmFindMeetingLocations]! [ Long] Wall-([Form]! [FrmFindMeetingLocations]! [TxtNearSubDistance]) and ([Form]! [FrmFindMeetingLocations]! [Long] + Val ([forms]! [FrmFindMeetingLocations]! [TxtNearSubDistance])) and ((TblStatePostCodeLongLat between KLat) ([form] [LAD] + Val ([forms]! [FrmFindMeetingLocations] [Lais] Wall-([form]! [Fmfaimaftimiting locations] [Tistianaiarsaibeeditins]) and [[forms]! [FMF & Mitting] TxtNearSubDistance])))) by order tblStatePostCodeLongLat.Suburb;

Thank God for this - I was going missing! Hope that solution helps anyone.

Cheers

winforms - C# Form - Property Change -

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
