Custom Workflow Activity & Web.Config

Hi,
I'm using a custom activity and I want to read some parameters from config.
Any way I read the appSettings I can´t find de keys. I tried diferent ways:
System.Web.Configuration.WebConfigurationManager.AppSettings["LogFilePath"];
System.Configuration.ConfigurationSettings.AppSettings["LogFilePath"];
System.Configuration.ConfigurationManager.AppSettings["LogFilePath"];
and the configuration exists on the FIM Portal web.config like this:
<configuration>
   <appSettings>
      <add key="LogFilePath" value="D:\temp2"/>
   </appSettings>
</configuration>
What can be happening??
Many thanks,
DD

The condition is met. The activity runs and logs several data about the request.
The log path is obtained in the activity parameters from UI. Now, I'm trying to read it from config without success (allways get empty string when reading the configuration. WCF configuration is also not being readed.
Thanks,
DD

Error says that 'No Plugin have been selected from list. Please select atleast one and try again'
In short my assembly is not considered as custom workflow activity.
I am giving my code let me know, If any thing is wrong.

Entity newContact = new Entity();
newContact.LogicalName = "contact";
newContact.Id = context.PrimaryEntityId;
newContact["new_nextbirthday"] = nextBirthDate;
service.Update(newContact);
If code is correct then has somebody faced this kind of issue earlier, what is resolution.

Highlight an invalid email address in a custom workflow activity in SharePoint Designer 2010

Hi,
I have created a custom workflow activity to send an email with the 'From' address being taken as input from the SharePoint Designer when this activity is used in a designer workflow. My requirement is to highlight an invalid email address(from address)
on click of 'Check for Errors' button in SharePoint Designer like it is done for mandatory inputs by default where it highlights such inputs if left blank. Is it possible?
Thanks in advance.

How to call an Azure Web API (2.2) - from Dynamics Custom WorkFlow Activity of Plugin c#

Hello,
I am specifically trying to call a web api, that has a FromBody.
However, I am trying to do it without having to use libraries (or nuget packages) that I cannot install on CRM of CRM Online.
It seems JSON newtonsoft is big... or I guess I could use my own custom formatter...
But I would love to see if someone has an example for posting to web API, versus an ASMX
Thanks

Wow I had this awesome thing typed up... and it wouldn't do it then wanted me to verify and then that messed up and I lost it all... Wow..
Anyway
[SOLVED]
Works from Plugin or Workflow activity
Use the Query string to pass things (not the body) or else you have to compress it and you can't use the libraries to DO that in the Sandbox... You CAN do that if you or on premise and do NOT isolate.. Then heck I did everything I wanted but for online
this was it.
You do NOT have to use WebClient, use HttpClient (follow the code below)
WebApi 2.2 is what I used
My signature for Webapi
You do have to clean up the response.. as the string you get back is JSON.. and you cannot use the JSON desieralizer...
Easy fix... just do a replacement of the \ and " to a " " space.. then Trim the result.. bingo a clean string response...
[HttpGet]
Public string MyMethod(string value1, string value2, string value3)
This will parse the query string so USE these are your parameters in your query string or the API will NOT work. ?value1=ddd&&value2=ddd&&value3=aaa
of course make up your own string names
IIS and Apache etc work differently so the AMOUNT of data you can send will differ per platform, per version of platform AND usually you can configure it.. IIS used to be like 2048 by default.. anything beyond that (as a total URL incoming) was truncated..
Not sure now. I know it was configurable
I got it working.. all my points are gone... but it's possible

How do I add my Custom Workflow Activity to FIM 2010 R2 SP1 installed on Windows 2012 server?

Hellos.
I have tried and failed to add my custom.dll into the Windows Server 2012 GAC.
We have a version of FIM 2010 R2 Sp1 running on Windows Server 2008 R2 and that was no problem. There seemed to be a gacutil.exe present on the system which added my assembly.
I cannot find gacutil.exe on the Windows 2012 Server.
I have downloaded and installed Windows SDK for Windows 8. However, when I try the gacutil.exe /i <myCustom.dll> nothing seems to happen.
Are there any guidelines how to add custom workflow activities to FIM when installed on a Windows Server 2012 system?
TIA
*HH

Well yes. It is fine when FIM is hosted on Windows Server 2008 R2.My difficulty is that I am using FIM 2010 R2 Sp1 and Windows Server 2012. No GACutility executable.
However, the problem has been resolved. Powershell can be used to modify the assemblies.
I opened a RunAs Administrator PS session. My assembly is in folder c:\Temp
Using Windows Explorer I browsed the folder c:\windows\assembly and noted the System.EnterpriseServices entries: version (2.0.0.0) and public key token (b03f5f7f11d50a3a)
(My version is 2.0.0.0 because when installing FIM and SharePoint 2013 the instructions I used suggested setting .Net version to be 2.0)
These powershell commands got me going...
PS C:\temp> [System.Reflection.Assembly]::Load("System.EnterpriseServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")
GAC Version Location
True v4.0.30319 C:\Windows\Microsoft.Net\assembly\GAC_64\System.EnterpriseServices\v4.0_4.0.0.0__b03f5f7f11d50...
PS C:\temp> $publish = New-Object System.EnterpriseServices.Internal.Publish
PS C:\temp> $publish.GacInstall("c:\temp\RunPowershellLibrary.dll")
PS C:\temp>
PS C:\temp>
PS C:\temp> iisreset
Amazingly I can see the assembly RunPowershellLibrary in my Windows 2012 GAC. :-)
Also, what is more cheering is that the custom activity actually works with FIM 2010 R2 Sp1.

Sharepoint 2013 designer workflow custom sendemail activity

Does anybody know sharepoint 2013 designer workflow custom sendemail activity. Current OOB sendemail action from designer workflow cancels the entire workflow when sendemail fails.
MCTS Sharepoint 2010, MCAD dotnet, MCPDEA, SharePoint Lead

Hi Amit,
What error did you meet when you used the OOB ‘Send Email’ action?
I suggest you fix the error rather than creating a new workflow ‘Send Email’ activity.
Of course, you can also customize a workflow activity to send email, there are two acticles about creating a custom workflow activity for your reference:

Custom workflow - How to go from single server to multiple?

I have been working on a project that involves developing a custom workflow activity for SharePoint 2013. I am developing it in a single server environment working with http. My problem occurs when deploying to multi-server environment with https (WFE, APP).
My question is how to deploy my solution to the new environment.
The steps:
Create a project - c# activity library
Add a workflow activity, add .xml
Deploy the .dll and .xml of project to "C:\Program Files\Workflow Manager\1.0\Workflow\Artifacts" "C:\Program
Files\Workflow Manager\1.0\Workflow\WFWebRoot\bin"
net sotp "Workflow Manager Backend"
net start "Workflow Manager Backend"
gacutil to deploy the .dll to GAC
iisrest
Create a project - empty SharePoint 2013 project
Add a workflow custom activity to project
Edit .actions4 and .xaml (my custom code from previous project is in this project now that i can drag and drop in .xaml)
Deploy to server, activate feature, open SharePoint Designer 2013 and choose the custom action that now appears when creating a 2013 workflow
This all works fine and dandy on my single server environment. Workflow is working like a charm. How should I go about deploying this to a multi-server environment with https? Does that server need Visual Studio on it also? I have continued to deploy the
.dll and .xml to the workflow manager backend folders. I have continued to deploy the .dll to the GAC also. When I upload the solution to the new site, it continues to work. When I open designer to create the workflow, it breaks and i cannot create or edit
any of the workflows on that site. Do i need to be doing something different because i am going from a http environment to https?
Let me know if this is unclear or if anyone needs more information. Thanks

If I understand correctly, your workflow still working fine in multi-servers farm but having problem in SharePoint designer. As far as I understand your custom activities should be deployed in the server where your workflow manager is running. Good architecture
would be to put the workflow in app server (or in it's separate server). But if you are also using HTTPs in multi-server farm whereas the workflow configured over HTTP, you might need to register the workflow (I'm not quite sure though, so you can try in some
test environment first).
I've worked with SharePoint 2013 workflow but I intentionally didn't develop custom activity. Rather I develop custom WCF service in SharePoint. And then used the service from workflow. This is how I could use a separate dedicated server for workflow (if
needed ever) without having any reference to SharePoint DLLs from inside workflow.

Custom workflow activities

I need to write a custom workflow to get more opportunities in the list of opportunities and then generate invoice with details.. do you have an idea??
thanks.

After having registered the custom workflow activity, you should have to restart Asynchronous process service and IIS...

PublishWorkflow error when workflow contains custom code activity

I've failed to get a custom code activity working within Workflow Manager 1.0 even though I believe I've performed all of the guidance steps provided.
As other posts, I get the usual 'cannot create unknown type' error:
client.PublishWorkflow( workflowName, @"..\..\TestWorkflow.xaml" );->
Cannot create unknown type '{wf://workflow.windows.net/$Current/$Activities}SendMailActivity'.
The activity is implemented as:
namespace SharedActivities

I've created an AllowedTypes.xml file containing the following:

========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
The assembly containing the custom activity is loaded into the Workflow host process.
I've configured my machine (development) to allow unsafe types.
I've also
uploaded my project so you can verify the implementation.
Thanks in advance, Adam

I did following step in your VS project.
Remove SendMailActivity from TestWorkflow.Xaml
Commented out "[assembly: XmlnsDefinition("wf://workflow.windows.net/$Current/$Activities", "SharedActivities")]
" line from SharedActivities assemblyInfo.cs file
build the project
Added SendMailActivity activity in TestWorkflow.xaml
run the program.
Above steps seems to be working for me..

Hi
We had to update following in assemblyinfo.cs file.
assembly: XmlnsDefinition("wf://workflow.windows.net/$Current/$Activities", "YourProjectNamespace")]
to
assembly: XmlnsDefinition("wf://{WorkflowManagerServerName}:12291/$Current/$Activities", "YourProjectNamespace")]for e.g.assembly: XmlnsDefinition("wf://workflowmanagerserver:12291/$Current/$Activities", "YourProjectNamespace")]
Only then custom code activity started working. However, this means, when we want to deploy in other environment with different URL, we need to re-build the assembly.
Is there any way by which we have this configurable?

from one day to the other the custom code activity within a SP2013 workflow gives me the following error:
Activity in progress Retrying last request.
Next attempt scheduled in less than one minute.
Details of last request:
HTTP Unauthorized to
http://server/subsite/_vti_bin/client.svc/sp.utilities.utility.ResolvePrincipalInCurrentcontext(input=@ParamUser,scopes='15',sources='15',inputIsEmailOnly='false',addToUserInfoList='False')?%40ParamUser='i%3A0%23.w%7Csp2013-dev%5Cadministrator'
Correlation Id: 9d507c00-1e24-af73-fcea-faa4a0a61ae1
Instance Id: 5c91916e-918b-453a-bf48-e61649afa3d0
After some time the workflow gets cancelled automatically. The custom code activity ran many times before without any errors.
Thanks a lot in advance!

HttpBinding not working when HttpHandler tag is present in web.config file

Hi,
I tried to add a WCF service in WCF Test Client using HttpBinding. But I couldn't add the service. I got the below error.
There was an error downloading 'http://localhost/Services/PostOffice.svc/_vti_bin/ListData.svc/$metadata'.
The request failed with an empty response.
Metadata contains a reference that cannot be resolved: 'http://localhost/Services/PostOffice.svc'.
The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.
If the service is defined in the current solution, try building the solution and adding the service reference again.
I removed the below code in the Web.Config, later I was able to add the WCF service to the WCF test client.
<httpHandlers>
<add type="System.ServiceModel.Activation.HttpHandler, System.ServiceModel.Activation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" path="Telerik.ReportViewer.axd" verb="*" validate="true" />
</httpHandlers>
I'm not sure with the above code. Could you please let me what is the reason behind it and what is the use of above code and if I remove it how does it affect my application.
Thanks in advance.
Sandeep

Hi Sandeep Pinniti,
Please try to add the following config in your config file:
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
The validateIntegratedModeConfiguration="false" will allow us to keep our httpHandlers section populated without throwing an error. And I have tested in my side,
it works fine.
