cannot open .Net form in Sales Logix
Posted: 01 Aug 07 5:14 AM

Hi Friends,
I am not able see the results when i include the .Net assembly(dll) or Form(exe) in the Sales Logix Architect. Basically i want to popup the .Net Windows form in the Sales Logix. For that i have written the code in .Net as,
Imports System
Imports System.Windows.Forms
Imports Sage.SalesLogix.NetExtensions
Public Class Form1
Implements Sage.SalesLogix.NetExtensions.IRunnable
Private SlxApplication As SalesLogix.ISlxApplication
Public Sub Initialize(ByVal SlxApplication As Sage.SalesLogix.NetExtensions.SalesLogix.ISlxApplication, ByVal LicenseKeyManager As Sage.SalesLogix.NetExtensions.Licensing.ILicenseKeyManager) Implements Sage.SalesLogix.NetExtensions.IRunnable.Initialize
End Sub
Public Function Run(ByVal Args() As Object) As Object Implements Sage.SalesLogix.NetExtensions.IRunnable.Run
Dim msg As String = "Hello .NET-SalesLogix World!" & vbCrLf & vbCrLf & _
"Argument passed: " & IIf(Args.Length = 0, "None", Args(0)) & vbCrLf & _
"Current userid: " & SlxApplication.BasicFunctions.CurrentUserID() & vbCrLf & _
"Connection String: " & SlxApplication.ConnectionString
MessageBox.Show(msg, ".NET MessageBox")
Return Nothing
End Function
End Class
And i have added the generated WindowsApplication1.exe to the .Net Extensions Manager,
and in the Sales Logix Architect, i have written the code as,
Sub Button1Click(Sender)
Dim Ext
Ext = Application.Managed.Create ("WindowsApplication1","WindowsApplication1.Form1")
Application.Managed.Run Ext,"Hi"
Application.Managed.Destroy Ext
End Sub
When i run the Sales Logix Client and click the Button1, i didn't get any output, neither the messagebox nor the Form1 opened.
Please help me to solve this problem. |

After this line:
Ext = Application.Managed.Create ("WindowsApplication1","WindowsApplication1.Form1")
Display the contents of "Ext" in a msgbox. Is it blank? If so, then the .NET Extentions probably didn't get installed correctly on that machine. You can do this manually be running the batch file in the SLX directory named something like InstallDotNetExtensions.bat.

Do not know if this matters but the second parameter in the run is an array, could there be a marshalling issue there.
AFAIK, the Ext value would be blank if it could not find the extension in the catalog as well. It would be good to see an image of the .net extension manager with the .dll registered to see #1 the Name. I assume it is correct but always good to see.
Ryan,
do you know if there are any exceptions thrown with the extension manager stuff is not registered correctly in SLX?

Unfortunately there are not. The result you'll see is the guid returned by the create method comes back empty/blank. That is lame, since your stuff just won't load and it doesn't say why. |

Ryan,
Thanks for your reply.
I have displayed the contents of "Ext" in the msgbox and it is NOT blank, it displays some GUID value. So i think there is no problem with .Net Extensions installation. But still i am not able to show the .Net form in Sales Logix.
Any help would be highly appreciated.
Thanks, |

OK. Seems we have this conversation going in about 3 different threads. Let's consolidate and just continue here 
If you're getting a guid back then extensions are installed right. Also, we can assume that you're using the right title & namespace.classname for the call to create.
In your code, no where is the form being shown. Your extension get loaded, that is, the form class is loaded and it's run method is invoked, but you're not actually "Showing" the form (ie: just because the class is instanciated won't show the form). You mentioned that the MessageBox in the .NET class isn't showing either, right?

yes, the MessageBox in the .Net class is also not showing.
As per your reply, you said that the run method is invoked, but the form is not "showing" as per the code. That means, do i need to include additional code to show the form? If yes, what could be that code? because i didn't find such code in this entire threads or articles. I tried in different ways, but didn't succeeded. Any inputs in this regard could be helpful.
One more interesting thing that i have noticed justnow and thought to share so that it may helps to solve the actual issue.
When i inherit the BaseRunnable Class, then it works fine and also getting the messagebox in .Net class .
But when i implement the IRunnable interface, then i am not getting anything, NO messagebox showing  .
Here is the code using both BaseRunnable class and IRunnable interface respectively.
'Using BaseRunnable class,
Imports Sage.SalesLogix.NetExtensions
Imports System.Windows.Forms
Public Class Class1
Inherits Sage.SalesLogix.NetExtensions.BaseRunnable
Public Overrides Function Run(ByVal Args() As Object) As Object
Dim msg As String = "Hello .NET-SalesLogix World!" & vbCrLf & vbCrLf & _
"Argument passed: " & IIf(Args.Length = 0, "None", Args(0)) & vbCrLf & _
"Current userid: " & SlxApplication.BasicFunctions.CurrentUserID() & vbCrLf & _
"Connection String: " & SlxApplication.ConnectionString
MessageBox.Show(msg, ".NET MessageBox")
Return Nothing
End Function
End Class
'Using IRunnable Interface,
Imports Sage.SalesLogix.NetExtensions
Imports System.Windows.Forms
Public Class Class1
Implements Sage.SalesLogix.NetExtensions.IRunnable
Public Sub Initialize(ByVal SlxApplication As Sage.SalesLogix.NetExtensions.SalesLogix.ISlxApplication, ByVal LicenseKeyManager As Sage.SalesLogix.NetExtensions.Licensing.ILicenseKeyManager) Implements Sage.SalesLogix.NetExtensions.IRunnable.Initialize
End Sub
Public Function Run(ByVal Args() As Object) As Object Implements Sage.SalesLogix.NetExtensions.IRunnable.Run
Dim msg As String = "Hello .NET-SalesLogix World!" & vbCrLf & vbCrLf & _
"Argument passed: " & IIf(Args.Length = 0, "None", Args(0)) & vbCrLf & _
"Current userid: " & SlxApplication.BasicFunctions.CurrentUserID() & vbCrLf & _
"Connection String: " & SlxApplication.ConnectionString
MessageBox.Show(msg, ".NET MessageBox")
Return Nothing
End Function
End Class
Inheriting the BaseRunnable class works fine and Implementing the IRunnable interface fails.
But i need to use IRunnable Interface to show the .Net windows form in sales logix.
Thanks,

Looking at the code that implements the IRunnable interface. First in the Initialize it does not seem that you arew assigning your ISLXApplication passed in as a parameter as a member variable. In the run method what is the SLXApplication pointing to ? I would think that the following should be done. Such as follows
public class Loader : IRunnable
{
ISlxApplication _application = null;
#region IRunnable Members
void IRunnable.Initialize(ISlxApplication SlxApplication, ILicenseKeyManager LicenseKeyManager)
{
_application = SlxApplication;
}
object IRunnable.Run(object[] Args)
{
string helloWorld = string.Format("Hello User {0} ", _application.BasicFunctions.CurrentUserID());
return null;
}
#endregion
} |

If you inherit from from IRunnable, then you're responsible for getting the reference to the SlxApplication object in the initialize method. You're not doing that and then attempting to use it in the run method.
You'll need to create a variable, class level scope, like this:
Dim SlxApplication As Sage.SalesLogix.NetExtensions.SalesLogix.ISlxApplication
Then, in the Initialize method you need to set the passed in SlxApplication object in your variable, then it will be good to use in the Run method. Does that make sense?
However, one thing to keep in mind as well, as I mentioned before, simply instanciating the Form1 class won't cause the form to show. The form won't show until either Show or ShowDialog is called on it.
You might be able to just call Me.ShowDialog in the Run method. What I would do is create a class in my project that get's invoked from SLX, and it loads a form, in a different class, in it's Run method. That's what I do.
Does that make sense? |

Ryan,
its amazing..... i got the results as per the expectations when i follow your instruction.. thank you very much.
But am curious to know one more thing, when IRunnable interface is implemented, then we creating a class lever variable SlxApplication and setting the passed SlxApplication object in the Initialize method and then using that variable in Run method for userid and connectionstring.
But when BaseRunnable class is inherited, we dont have Initialize method and there is no SlxAppliation object passed as an argument in Run method, then how the SlxApplication object referenced and how the userid and connectionstring values are populating?
Since in both the cases, Run method is same which doesn't take SlxAppliation object as a parameter.
Then how the SlxApplication object is referenced to get the userid and connectionstring values when BaseRunnable class is inherited?
Is my analysis going in a wrong direction?
Thanks a lot for your support. |

Iam getting the returned value from Application.Managed.Create as blank that would most likely mean one of two things as you said:
1) The "Namespace.Classname" for the assembly or the "Title" as defined in the .NET Extentions manager do not match with the code iam using to invoke it.
2) The .NET Extention files did not get properly registered on the machine iam testing on. If this is the case, i can fix this by manually running the batch file named "RegisterSLXNetExtentions.bat" found in the SalesLogix directory.
As my code is correct as per 1st point , i checked the 2nd point . When i manully ran the batch file named "RegisterSLXNetExtentions.bat" found in the SalesLogix directory , i got the following error while running the bat file:
E:\Program Files\SalesLogix>C:\WINNT\Microsoft.NET\Framework\v2.0.50727\RegAsm.e

So, Lets talk Interfaces first. When an interface is implemented your componentis are saying I implement a contract and you can call the contracts known methods. An interface cannot have any code in it and is only signatures (method, properties ...) whereas inheriting a class means that the deriving class gets all of the inheritied functionality . In the instance of the BaseRunnable, the functionality and even the property SlxApplication is assigned for you and available. Basically the BaseRunnable has implemented the IRunnable interface and takes care of the initialize call for you. Since .net does not have multiple inheritance and you wanted to augment your form directly to be shown you needed the IRunnable interface, and as such you needed to manage the initialization functionality your self.
I might recommend that you lookup .net programming (VB.net or C#) and read about classes vs. interfaces. Once you get this concept under you belt things will be much better.
Make Sense? |

As Mark mentioned, the differences between an interface, such as IRunnable, and a class, such as BaseRunnable, is that the class can (and will) contain implementation code. An interface does not. So, in the case of BaseRunnable, it already has the Initialize method internally and has a class level variable called SlxApplication. Those are already built-in. When you inherit from BaseRunnable then those built in things become a part of your class as well. Does that make sense?

| As Mark already mentioned, yes, you do need to have rights to the write to the registry. When that batch file is run it is registering the DLL for COM interop. This requires access to the registry. |

Thanks....i got it now.
It was mentioned in this site that, IRunnable interface and BaseRunnable class are the entry points, but it was not mentioned that BaseRunnable class inturn implements IRunnable interface, hence its confused.
I have clear idea now about what happens when interface is implemented and what happens when class is inherited.
These forms are very useful to get the solutions for the problems and also to improve the skills.
Thanks for your support. |

Keep in mind, you'll only need rights to the registry to install the .NET extensions. After they are installed you won't need the elevated rights any longer. You could even get one of your IT guys to right-click the BAT file and do a "Run As" to install and be done with it.
