Invoke code activity VB.Net example

[Mount (Ado)]

Hi there,

I am studying the invoke code activity in the new version of UiPath(V2017.1.6435). But I found that there is only a small resource about this new activity both inside the Forum and Google search. Does anybody have done a research about this new activity? I have some questions about it:

1. Can we write VB.Net class/module inside this activity?
2. How to connect Excel with VB.Net code directly?

Could anyone provide some training materials or some example codes? Appreciate it in advance.

I am learning an online tutorial(https://www.tutorialspoint.com/vb.net/index.htm about VB.Net, but I found difficulty to connect it to this Invoke code activity.

Best regards
M

Ok…

first:

You can reffer to methods available in the .NET library, the imports are done using UiPath.

second:

Automate Excel from Visual Basic .NET to fill or obtain data by using arrays...

I am quoting @andrzej.kniola here "Personally I just use it solely for void methods and from useability perspective " even this is related to invoke methods I think you don’t need to reinvent the wheel here.

InvokeCode Example

Hi, The official training materials might not be up to date yet as this activity has only just been added to the Community edition. I can give a small example right here though. Just as with “Invoke Workflow”, you can specify arguments that will be accessible inside: [arguments] But instead of a workflow filename you enter Visual Basic code you want to execute, directly into an editor window. Suppose I want my code activity to randomly shuffle its string argument. I could program this as foll…

Display Form through UIPath

Hi Richard, This would be that way in VB.Net Dim frm As New System.Windows.forms.form Dim bar As ProgressBar = New ProgressBar() bar.Location = New System.Drawing.Point(50, 20) bar.Name = “progressBar1” bar.Size = New System.Drawing.Size(171, 23) bar.TabIndex = 0 bar.Style = ProgressBarStyle.Marquee bar.Minimum = 0 bar.Maximum = 100 frm.Controls.Add(bar) frm.Show() Importing System.windows.Forms first is required, note also that you will get no intelisense from it inside the code …

Create multiple field input dialog

Probably, this seems to be quite a popular request that keeps coming back. In the meantime (and since I can’t sleep for w/e reason ) here’s a base to expand upon and customize for your needs:

Messy code inside

using System; using System.Collections.Generic; using System.Linq; using System.Windows.Forms; using System.Activities; namespace WebHelpers.InputHelpers { public sealed class MultiDialogActivity : CodeActivity { [RequiredArgument] public InArgument<…

Guys,

Here is a detailed article on that

How To Use Invoke Code Activity – In UiPath

[Pavithra (Pavithra Ragunathan)]

I tried the same in many ways, Looks like there is no way we can write a function and call it from within VB.NET invoke Code activity. All the examples stated here is a simple code where you send some argument values and get something out of it…

Our need is to write a code that looks like this:
// Code line 1
//Code line2
//Call function xyz
//Code line3

Function xyz(ByVal x as Integer, ByVal y as Integer)
//do something
End Function

Funnily, this scenario works perfectly when we are using a UiPath with C# code. A little disappointed that this basic feature is not working in VB.NEt UiPath that is predominantly used everywhere.
