I want to be able to pass through multiple Latitude and Longitudes and perform calculations rather then create a different function for each
I have one static Lat/Long and then need to compare that to 7 different Lat/Long

I have a collection of latitudes and longitudes and I'll be grabbing sets of these and want to draw a polygon based on them.The datasets won't be the outline so will need an algorithm to establish which ones make up the outline of a polygon containing all the latitudes and longitudes supplied. This polygon needs to be flexible so the polygon can be concave if the points dictate that.
My code below produces a horrible looking polygon. As explain in my first post I want to create a nice concave or convex polygon based on the latlng's provided.Just need a way of plotting the outer latlngs.

var myLatLng = new google.maps.LatLng(51.407431, -0.727142);

Need advice on what is the best approach to get the auto incremented id to be the same on multiple forms.
Basically I am using VB .Net with SQL Server as the backend. I wrote a few stored procedures to insert data and then I am calling the stored procedures on the front end. I have 3 forms and once the first form is submitted it generates an autoID and then takes the user to 2nd form.
In the second form I have a separate insert stored procedure is there a way to grab the id that the first form generated and for it to be consistent. Or should I store it in a variable after they submit the form and then call it in the second form.
I have about 10 boxes on my form1 that the user will populate, I am looking for a "Best Practice solution to pass the values across to form2 and form3. Would like the user to be able to edit the value on either form and have the chnage carry over to the other forms.

I have tested my code in order to pass single value to single parameter field in crystal report from VB.NET Form, it is ok but the problem is that I want to pass multiple values to only one parameter field called "Product Name" and it displays only one last record.
I want to display like this
Receipt : 0001 Product Name
pencil
pen
stamp
book

I already set parameter field "productname" for allowing to multiple values, but it is still the same.
I need to open up a cmd prompt, then run a file called adb.exe which opens a shell to communicate with my android cell phone...
Heres what I need:
My Form1
Label1.Text = "adb.exe shell"
Label2.Text = "su"
Label3.Text = "mkdir /etc/folder"

Heres the problem... I can execute any normal dos command automaticly, but once i open the ssh prompt (adb.exe shell), i dont know how to keep putting commands in there...
The commands are stored in strings, and i need to take the commands from the strings, and type them into the command prompt like above.
When I click on button1, employee_id and P values need to be transferred from button1_click to Cal_Category13() and go through all the calculation. After the calculation, udtnew.X and udtnew.MTD values need to be transferred back to button1_Click
I've no problem to return multiple values Cal_Category13().MTD and Cal_Category13().X from Cal_Category13() to button1_Click but i've no idea how to transfer employee_id and p values from button1_click to Cal_Category13().

I'm trying to make a longitude and latitude converter. I use Google maps to get longitude and latitude for my handheld GPS but there longitude and latitude is a different type then my GPS uses. I have to convert it before putting it in my GPS.
I made a very simple program using VB 2008 that open up right to Google maps and at the top of the program i want to put the converter.
I have done a lot of research and still i am not able to wright a code that will do the conversion. For the conversion Need to multiply the decimal part of the longitude and latitude by 60
For example if i had 40.313043,-97.573244 I would multiply .313043 by 60 witch = 18.78258 and then i would multiply .573244 by 60 witch = 34.39464 The finale longitude and latitude would be 40 18.782, 97 34.394
how to retrive longitude and latitude, perhaps even diaplay several address on a map, be it google yahoo mapquest??
I want to add a feature that takes 6 propertys(houses) and measures the distance from each to the users location
I'm developing a database in VB.NET-Code First. I would like to add Latitude and Longitude to both Locations and Postal Codes. Right now i'm adding a GeographicCoordinate to each class.
[Code]...
I would like to know about convertion from (x, y) to (latitude, longitude)?
For Example:
In my project(windows form - VB.NET) i have a Panel (control) and have a MouseMove Event then when i moving the mouse it have a location such as:
Label1.text = e.X
Label2.text = e.Y
So how to convert it to?:
Label1.text = Latitude(e.X)
Label2.text = Longitude(e.Y)
Is it possible to get latitude and longitude coordinates from an address in a vb.net application?

View 6 RepliesI am new to vb.net, but i have good knowledge in Vb. I have a set of latitude and longitude, I need to find which county this set belongs to.
View 2 RepliesI have a piece of code:
Dim Latitude As Double = row("fltLatitude")
Dim Longitude As Double = row("fltLongitude")
Most of the lat/longs that are being fetched from the db using SP are retrieved in properly, except for a couple of records which do not include a period to indicate a lat/long value.I have tried using these:
Convert.ToDecimal(Latitude)
CDec(Latitude)
decimal.Parse(Latitude)
but none of them are working.
i have a decimal number like 35,23456834 the rapresent a latitude or longitude (in degree but with decimal form for the decimal )
My need is to transform that number in xx° - xx' - xx'' in a variabli of string
I want to convert British OSGB 36 co-ordinates to WGS 84 (i.e. "standard" latitude and longitude), in order to plot them into a KML file for Google Earth.I should probably add that my question is not "How do I write a KML file?". My question is "How do I convert between these 2 co-ordinate systems?"!!I was hoping there would be a library that I could use, rather than rolling my own function - it seems like the sort of thing some-one else would have implemented.

View 8 RepliesI have a table with long/lat values and another table with a project-id and long/lat/radius (circle).Now I need to find out which project matches the long/lat values from the first table.Is there an easy way to do that?
View 2 RepliesIf there is a formula to change a latitude and longitude into a single number? I plan to use this for a database table in software that provides routing for deliveries. The table row would have that number as well as the postal address. The database table would be sorted in ascending numeric order so the software can figure out which address the truck would need to go to first, second etc.
For example I would use the following numbers for the latitude and longitude:
Lat = 40.71412890
Long = -73.96140740
Additional Information: I'm developing an Android app using Basic4Android. Basic4Android uses a VB or VB.Net syntax with SQLite as the database. Part of this app will have route planning. I want to use this number as the first column in an SQLite table and the other columns will be for the address. If I do a query within the app that sorts the rows in numerical ascending order, I will be able to figure out which postal address are closest to each other so it will take less time for me to go from house to house.
For example, if the numbers were:
194580, 199300, 178221
I can go to postal address 178221 then to 194580 and finally to 199300 and I won't need to take the long way around town to do my deliveries after they were sorted. As an alternative, I would be happy if there was an easy way to call a web service that returns maybe a json response that has the single number if I send a postal address to the web site. Basic4Android does have http services that can send requests to a web site.
calculate the gps coordinates of points of a specific distance, namely 22 feet apart, on the circumference of a circle. I know the beginning gps coordinates and the radius. I am pretty sure the haversine, or the speherical law of cosines has the answer, but its been a long time since I have used any trig formulas and I cant figure it out. I am using decimal degrees and am programing in this vb.net.
