Hello,

Please let me know how I can invoke Baan with a specific bwc config from .NET using C#?

eg: In VB.NET, to invoke a specific BWC, the command CreateObject("Baan4.Application.someuser") can be used.

I would like to know how the same can be achieved using C#?

Thanks for your time and help.

Hi Punitha,
I used something like this


object Baan = null ;
Type t;
t = Type.GetTypeFromProgID("Baan4.Application.someuser");
Baan = Activator.CreateInstance(t);
object[] Parameters = new Object[1];
Parameters[0] = 3600;

//Baan.Timeout = 3600;
Baan.GetType().InvokeMember("Timeout", BindingFlags.SetProperty, null, Baan, Parameters);

Parameters = new Object[2];
Parameters[0] = "otccomdll...";
Parameters[1] = "function.name...";
Baan.GetType().InvokeMember("ParseExecFunction", BindingFlags.InvokeMethod, null, Baan, Parameters);
...
//Baan.Quit();
Baan.GetType().InvokeMember("Quit", BindingFlags.InvokeMethod, null, Baan, null);

Dear Gooch,

Thanks much for your help. That really helps me a lot.

Out of curiosity, I noticed that Baan provides the following namespaces 'Baan4' and 'BWCLib'.

"Baan4Class" in "Baan4" provides the 'parseexecfunction', 'returnvalue' etc. methods,properties etc.

BWCLib provides the 'Configuration Class' etc.

Is there any way the above two can be utilised without using the 'Activator'?

Thanks again.

Dear Punitha
I prefer late binding. But MSVS and C# support two ways.
If you want I think you could create marshal object with .NET
Just import type library
And can you answer what's wrong with Activator?
I'm going to create some program for ASP.NET in some days

Best regards,

Dear Goooch,

Using 'activator' is fine. I was just trying to figure out the methods and props. provided by Baan and how to use them.

But, your response has helped me in my project.

Good luck to you in your future .NET projects.

Dear Goooch,

I've used your code sample to connect with a custom made function in Baan. Now does this custom made function return a int value telling me if the actions where successfully executed or not, and if not, what wend wrong.

Calling this function, and sending my data works fine but I can't seem to get the return value. I was hoping you know how to do this and perhaps share some code to accomplish this?

Thank you very much.

Best regards,
Marijn

Hi Marijn,
try this
Int32 v = (Int32) Baan.GetType().InvokeMember("yourmethod"....

Hi Goooch

Thank you for a quick reply.

I've tried this already, I keep getting 0 or -1 back when i'm 100% sure of the fact that I should get 4 back (says something about trying to insert a key that already exists).

I think that this isn't possible but I would like to hear from people who've successfully created such a feature.

Thank again.

Best regards,
Marijn Rispens

Sorry
I've just tried this and it worked fine


Int32 v=(Int32)Baan.GetType().InvokeMember("ParseExecFunction", BindingFlags.InvokeMethod, null, Baan, Parameters);
String s = (String)Baan.GetType().InvokeMember("ReturnValue", BindingFlags.GetProperty, null, Baan, null);
The result of previous function's call (that was in Parameters Array) was in 's'.
The result of ParseExecFunction call was in 'v'

Best regards,
Goooch

Hi Goooch

It works!! Thanks a lot!

Best regards,

I was checking out this posting while trying to figure out how I can work around having to remoted into 80+ PC to set up some new read only bw config files. The accounts will have predefined passwords that us admins will put in the config file and check the save password. We found in testing that when we push out the setup configure file it removes the stored password, so we can push out the configure file but still requires for us to remote onto the PC to setup the password.
So was thinking maybe I can write a c# console app that will start that predefined configuration file and some how pass the password when starting baan application, is there a way to pass the password and if so what is the syntax for the command?

Hey guys:

I noticed in the above posts that they're using a generic 'object' class type for the Baan automation class. That forces the programmer to use reflection to call the class' members. Instead, you cad add the 'BaanERP Type Library' reference to your C# project and then use the following code:

var baanobj = (IBwCOleAutomationServer)Activator.CreateInstance(Type.GetTypeFromProgID("Baan.Application.yourinstancehere"));

The object type for baanobj will be the IBwCOleAutomationServer interface. From here on you can call the object's members normally, like:
int x = baanobj.ParseExecFunction("ottstpapihand", "stpapi.stpapi.put.field(\"tfgld1101m000\",\"tfgld101.ttyp\",\"G01\")");

Makes everything easier.

I have a similar issue but I have to enter the login information in Baan dialog. I am not abl e to put the username and password in the .BWC file and automatically use that.

Is there a way to force our C# program to use a specific .BWC configuration file?

The code I have looks like this but it does seem to work


using Baan4;

connectBaan.Timeout = 36000;
connectBaan.ParseExecFunction("aBaanDllName", @"theBaanFunctionCall(""withOptParms"")");
Console.WriteLine(connectBaan.ReturnValue);
connectBaan.Quit();


Can you please help?

Thanks,
Baannoob

With the client today each bwc has its own connection on the automation tab. So I can have a prod.bwc with baan4.application.prod, then I can have a .bwc with baan4.application.prodauto. When I want to use automation I use the baan4.application.prodauto in the connection name.

Hope that helps - I only ever just played with this.
