What are the parameter values to the Cylindrical function supposed to be, and what result should it return?

Hello all.
Does anyone know how to send multiple latitudes & longitudes from VB.net to Google Maps and receive from Maps services what is the best route?
I'd like to receive something like this:
1) Address B
2) Address A
3) Address D
4) Address C
It would indicate me where to go first.
Thanks.
Paulo

Ah the old drunkards walk - I designed one of these in the 90s, for just one city. I'm betting Google does not have such a facility freely available, it is a MAJOR task to get right as you must take into account one way street and traffic conditions.

The API accepts multiple addresses, and returns the results in the form of arrays. The actual format to be used will depend on which version (iOS, Android, JSON) that you are using. The Google documentation should help.

I posted this C# board first which was a mistake again I apologize. I work for this company where the old programmer was in the process of rewrite the source code with no documentation at all from VB.Net to C# Now we have 4 programs total and they all update from the same database and get price updates on items. My problem is on one of the programs if a customer was to do full sync which is the whole database list of well 60,000 items I get OutOfMemoryException when it imports the last category Items. Here are the Exceptions Quote: Exception thrown: 'System.OutOfMemoryException' in System.Data.dll
Exception thrown: 'System.OutOfMemoryException' in Microsoft.EntityFrameworkCore.Relational.dll
Exception thrown: 'System.OutOfMemoryException' in Microsoft.EntityFrameworkCore.Relational.dll

Looks to me "it" is reading, updating and creating (Entity Framework) entities; but nowhere is it writing ("flushing") these entities to a database or garbage collecting. So, "memory" just fills up.
This may work for a few items (for whatever purpose), but not apparently for "60,000" (at one time).
For Each row In DataSetPricing.Items

What about using
XStreamingElement When reading the file
DataSetPricing.Items.BeginLoadData()
DataSetPricing.Items.DataSet.ReadXml(String.Format("{0}\Items.xml", My.Computer.FileSystem.SpecialDirectories.Temp), XmlReadMode.InferTypedSchema)
DataSetPricing.Items.EndLoadData()
BackgroundWorker.ReportProgress(60)
How do I change the code?

Hi,
i want to create an option when I click right on 2 files.
I added the regkey in HKCU\Software\Classes*\shell and command.
but when I select my option it is executed twice. Once on file 1 and once on file 2. I want to run the command on the 2 files at once so that I can check that there are exactly 2 files selected as a parameter and than I can do my stuff with those files.
How can I make windows run my command on the 2 files in 1 instance of my command?

It will now launch two instances, right?
There's some articles here on preventing a second instance of your app, and how to send the starting-params to the first instance of the application, before exiting.
That way the first instance of the app could receive the params for the second instance and do it's work, while the second instance exits.

I have a TreeView control within the main form. The main form processes the normal
drag/drop event processing. The drag/drop operation performs successfully except for this
little problem.
When I do a DoDragDrop() operation within the TreeView, when dragging the mouse 'within' the
TreeView, the main form receives drag drop events. I only want the 'main form' events when the mouse is within the main form client area. What have I missed?
Thanks
Private Sub FolderTree_Drag(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemDragEventArgs) Handles MyBase.ItemDrag
If e.Button = Windows.Forms.MouseButtons.Left Then
Dim node As TreeNode = CType(e.Item, TreeNode)
Dim dataObject As New DataObject()
Dim sFiles As New StringCollection
sFiles.Add(node.FullPath)
dataObject.SetData(ConstDragDropFormat, sFiles)
' Invoke the drag and drop operation
DoDragDrop(dataObject, DragDropEffects.Copy)
End If
End Sub
I have tried this code in the TreeView but it does not help.
Private Sub TreeView_DragEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles MyBase.DragEnter
e.Effect = DragDropEffects.None
End Sub
Private Sub TreeView_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles MyBase.DragDrop
e.Effect = DragDropEffects.None
End Sub
Private Sub TreeView_DragOver(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles MyBase.DragOver
e.Effect = DragDropEffects.None
End Sub

Hi there
Is there any method for IPC between VBS and C#?
Hope to use Sendmessage API, but I couldn't find any example how to send message from VBS
If you also suggest other way to send message from VBS to C#, It would be very appreciated
Thank you
|
|
|
|
|
What are you really trying to achieve ...?
|
|
|
|
|
There is no IPC between languages. There is between applications.
You haven't described what you're doing in VBS and in the C# code, not even what kind of app you've written in C#. Is this a COM component, a Windows Forms app, WPF app, ... ? What?
VBS cannot directly call Win32 functions, including SendMessage, but it can be done using a custom COM-component.
You're going to go into a lot more detail about what you're doing to get any meaningful answer.
|
|
|
|
|
Oh, I'm sorry to give any detail that I want to do.
Because I'm beginner here, just thought WPF is the only APP for C#, I applogize
My plan is, send data from VBS to WPF app.
I mean, Communication Between two programs in local computer not through the internet
For example,
Dim Data = "Hello"
I want to transmit "Hello" from VBS to WPF APP, and invoke popup message from WPF APP as "Hello"
If I can make two-way communication between VBS and WPF APP, it would be the best
but, To build VBS for Trasmission and WPF for Reception is also enough
Thank you
|

A better what to do that would be to use an Inter Process Communication method (IPC), like named pipes or memory mapped files.
The problem here is that VBScript doesn't have any native way to do any kind of IPC. It would take writing a COM-based component that your VBScript code can use (see the CreateObject function) to handle the IPC heavy lifting.
You would also have to implement the "server-side" of the communication channel in your WPF app.

Dear friends
please help me how to deal with this error object variable with block variable not found not found
|

You have to show us the code that is causing the error for us to even have half a chance of helping you!

Dear Friends at code project,
The code i use is as follows
Private Sub BtnExcel_Click(sender As Object, e As EventArgs) Handles btnExcel.Click
Try
Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim dataSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
Dim path As String = "C:\Users\Abhimanyu Singh\Documents\excel\SalarySlip.xlsx"
MyConnection = New System.Data.OleDb.OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;")
MyCommand = New System.Data.OleDb.OleDbDataAdapter("select * from [salaryslip$]", MyConnection)
dataSet = New System.Data.DataSet
MyCommand.Fill(dataSet)
DataGridView1.DataSource = dataSet.Tables(0)
MyConnection.Close()
Catch ex As Exception
MsgBox(ex.Message.ToString)
End Try
End Sub
End Class
It works well for a single Excel file but if i try to open another fileit gives me error
"OBJECT VARIABLE OR WITH BLOCK VARIABLE NOT SET"
IAM NOT ABLE TO MOVE AHEAD PLEASE SUGEST REMIDIES
|
|
|
|

Again. Without the code you're using and a description of any problem or errors you're having, it's impossible for anyone to help you.
Stop typing as little as possible.

I'm using ToolStripProfessionalRenderer to customize a toolstrip. The toolstrip buttons are generated programmatically as needed. The program starts with three buttons. I'm using a LinearGradientBrush to paint the ToolStripButtons, but only the first one (left) gets the gradient. Using the renderer is new to me, so I'm probably missing something obvious.
Private Sub menuRndr_RenderButtonBackground _
(sender As Object, e As ToolStripItemRenderEventArgs) _
Handles Me.RenderButtonBackground
Try
If e.ToolStrip.Equals(main.tabs) Then
Dim p As New Pen(Brushes.Black, 1)
Dim lgb As New LinearGradientBrush(e.Item.Bounds,
Color.SteelBlue,
Color.WhiteSmoke,
LinearGradientMode.Vertical)
e.Graphics.FillRectangle(lgb, e.Item.Bounds)
e.Graphics.DrawRectangle(p,
New Rectangle(New Point(e.Item.Bounds.Left, e.Item.Bounds.Top),
New Size(e.Item.Bounds.Width, e.Item.Bounds.Height)))
End If
MyBase.OnRenderItemBackground(e)
Catch ex As Exception
MsgBox(ex.ToString)
End Try
End Sub
