How to set current cell on SAP GUIContainerShell in C#?

I am automating my work with SAP GUI script at the moment and whilst trying to recreate the recorded macro I am having an issue at one particular point which I don't know how to translate.
session.findById("wnd[0]/shellcont/shell/shellcont[1]/shell").setCurrentCell 1,"MAKTX2"
session.findById("wnd[0]/shellcont/shell/shellcont[1]/shell").doubleClickCurrentCell
session.findById("wnd[1]/tbar[0]/btn[0]").press
I have read through the SAP GUI Scripting API pdf and am struggling to see how I action the .setCurrentCell 1,"MAKTX2" part. I am accessing the container cell with the following:
GuiContainerShell materials = (GuiContainerShell)session.FindById("wnd[0]/shellcont/shell/shellcont[1]/shell");
How do I make "materials" double click "MAKTX2"?
Edit: Full SAP GUI script:
SapROTWr.CSapROTWrapper sapROTWrapper = new SapROTWr.CSapROTWrapper();
object SapGuilRot = sapROTWrapper.GetROTEntry("SAPGUI");
object engine = SapGuilRot.GetType().InvokeMember("GetScriptingEngine", System.Reflection.BindingFlags.InvokeMethod, null, SapGuilRot, null);
GuiApplication GuiApp = (GuiApplication)engine;
GuiConnection connection = (GuiConnection)GuiApp.Connections.ElementAt(0);
GuiSession session = (GuiSession)connection.Children.ElementAt(0);
GuiFrameWindow frame = (GuiFrameWindow)session.FindById("wnd[0]");
GuiTextField jobsite = (GuiTextField)session.FindById("wnd[0]/usr/subSA_0100_1:SAPMZCX_CSDSLSBM5001_OFS_OTS:2410/subSA_2410_1:SAPMZCX_CSDSLSBM5001_OFS_OTS:2510/ctxtKUWEV-KUNNR");
jobsite.Text = "I033";
frame.SendVKey(0);
GuiLabel aggregates = (GuiLabel)session.FindById("wnd[1]/usr/lbl[12,3]");
aggregates.SetFocus();
GuiFrameWindow frame2 = (GuiFrameWindow)session.FindById("wnd[1]");
frame2.SendVKey(1);
GuiContainerShell materials = (GuiContainerShell)session.FindById("wnd[0]/shellcont/shell/shellcont[1]/shell");

To be honest I can't help you with C#, but perhaps the SAP interface is generic enough anyway. Thing is, session.findById("wnd[0]/shellcont/shell/shellcont[1]/shell") gives you a reference to an object of type GuiShell or GuiContainerShell or whatever it's called. On this reference, you can call the methods defined for this type. So in the same way, when you do
session.findById("wnd[0]/shellcont/shell/shellcont[1]/shell").setCurrentCell 1,"MAKTX2"
You're just getting the reference first, and then applying the method setCurrentCell on it, all on the same line.
When you did in C#
GuiContainerShell materials = (GuiContainerShell)session.FindById("wnd[0]/shellcont/shell/shellcont[1]/shell");
you gave this reference a name materials, and provided that line works correctly, I guess you can just say now:
materials.setCurrentCell(1, "MAKTX2")
materials.doubleClickCurrentCell

Sync to all CLs within a certain Date/Time range

My documentation and Google-fu is seriously failing me on this one, so:
how do I use P4API's GetChangelist() function to sync a range of files (i.e. all files from #now to #twoDaysAgo)? I can easily construct the command line to do this like so:
p4 changes -s submitted //...#2016/12/01,2016/12/06
but the API wants me to interface with the server via
GetChangelist(Options options, FileSpec[] files)
It's driving me crazy that I have to construct a combo of Options and Filespecs[] to make the request instead, and (AFAIK) can't just pass the actual command line string. Especially because all documentation seems to be non-existent.
Can somebody enlighten me as to what kind of filespec parameters I have to pass along? (I think that's what I need to use to specify the fact that I want to get a range of all CLs inside a certain time?) Thanks!
(As an aside: I was surprised there isn't a "P4API" tag yet, and I can't create one.)

And here's the non-command line version that you really want to use, from the Perforce documentation (once you find it :))
PathSpec path = new DepotPath("//depot/...");
DateTimeVersion lowerTimeStamp = new DateTimeVersion(new DateTime(2016,12,06));
DateTimeVersion upperTimeStamp = new DateTimeVersion(DateTime.Now);
VersionSpec version = new VersionRange(lowerTimeStamp, upperTimeStamp);
FileSpec[] fileSpecs = { new FileSpec(path, version) };
ChangesCmdOptions changeListOptions = new ChangesCmdOptions(ChangesCmdFlags.FullDescription | ChangesCmdFlags.IncludeTime, null, 0, ChangeListStatus.None, null);
IList<Changelist> changes = m_Repository.GetChangelists(changeListOptions, fileSpecs);

Alright, after a couple more hours of digging, I have found that there is a way to feed the actual command line parameters to the command. You create a DepotSpec, and then something like this is working for me to restrict the time range for CLs retrieved from the server:
ChangesCmdOptions changeListOptions = new ChangesCmdOptions(ChangesCmdFlags.FullDescription|ChangesCmdFlags.IncludeTime, null, 0, ChangeListStatus.None, null);
FileSpec[] fileSpecs = new FileSpec[1] { new FileSpec(new DepotPath("//depot/...#2016/12/05 21:57:30,#now"), null, null, null) };
IList<Changelist> changes = m_Repository.GetChangelists(changeListOptions, fileSpecs);
All this might be "indulgent smile" old news to people who've worked with the API for a while. It's just all a bit confusing to newcomers when documentation like the two pages mentioned in this post ("FileSpec object docs", "SyncFiles method docs") are offline now: Perforce Api - How to command "get revision [changelist number]"

Call a SAP transaction/program with the SAP 3.0 .NET Connector

I am aware of the option to call RFC-functions with .NCo 3.0 but is it possible to call transactions/programs directly with the SAP Connector? (Like using the fields defined in SAP as parameters and fill them, or use a variation, something like this?).
This answer provides a workaround that I am aware of, and sure - I could call a VBScript from my C# code but that is not what I want to do.
I also checked all of the 64 Questions tagged with sap-connector but there was nowhere a direct answer if it is possible or not.
Also the SAP documentations I got from the SAP marketplace aren't mentioning transactions/programs at all. Does this mean it is not wanted/possible ?
If so, why is it possible to do it with macros/pre-recorded VBScripts but not with the .NET-Connector ? Or am I just doing something wrong ?
When I try to call a program/transaction with the standart-code:
SAPHandle.ECCDestinationConfig cfg = new SAPHandle.ECCDestinationConfig();
RfcDestinationManager.RegisterDestinationConfiguration(cfg);
RfcDestination dest = RfcDestinationManager.GetDestination("QP2");
dest.Ping(); //works fine -> Connection is OK
RfcRepository repo = dest.Repository;
IRfcFunction zzmkalzzm23fnc = repo.CreateFunction("ZMZKALZZM23");
it gives me the following (expectable) error:
metadata for function ZMZKALZZM23 not available: FU_NOT_FOUND:
function module ZMZKALZZM23 is not available

CreateFunction, as the name already suggests, creates a proxy to call a remote-enabled function module in the SAP system. You can't call a transaction or program this way. I am not aware of any way to call a report with SAP .Net Connector. The solution you linked uses SAP Gui, which provides the SAP system with a UI to display graphical elements. AFAIK, SAP NCo doesn't provide such an interface and you can't call reports from NCo.
However, there are products that allow you to execute transactions and catch their output. We are using the product Theobald Xtract to extract SAP ERP data for BI purposes, but they also have a more generic .Net library (Theobald ERPConnect) available that may be able to provide this functionality. It won't be as simple as calling a function and extracting the strongly typed data, but with some filtering you should be able to get the output you need. Those products are not cheap, but they do provide a nice set of functionality you otherwise would have to reinvent yourself.
Some example code how you could call the transaction you ended up calling through VBS-Scripts.
From the Theobald ERPConnect Knowledgbase:
private void button1_Click(object sender, System.EventArgs e)
{
// Reset the batch steps
transaction1.BatchSteps.Clear();
// fill new steps
transaction1.ExecutionMode = ERPConnect.Utils.TransactionDialogMode.ShowOnlyErrors;
transaction1.TCode = "MMBE";
transaction1.AddStepSetNewDynpro("RMMMBEST","1000");
transaction1.AddStepSetOKCode("ONLI");
transaction1.AddStepSetCursor("MS_WERKS-LOW");
transaction1.AddStepSetField("MS_MATNR-LOW",textBox1.Text);
transaction1.AddStepSetField("MS_WERKS-LOW",textBox2.Text);
// connect to SAP
r3Connection1.UseGui = true;
R3Connection r3Connection1= new R3Connection("SAPServer",00,"SAPUser","Password","EN","800");
r3Connection1.Open(false);
// Run
transaction1.Execut e();
}

C# code completion with NRefactory 5

I just found out about NRefactory 5 and I would guess, that it is the most suitable solution for my current problem. At the moment I'm developing a little C# scripting application for which I would like to provide code completion. Until recently I've done this using the "Roslyn" project from Microsoft. But as the latest update of this project requires .Net Framework 4.5 I can't use this any more as I would like the app to run under Win XP as well. So I have to switch to another technology here.
My problem is not the compilation stuff. This can be done, with some more effort, by .Net CodeDomProvider as well. The problem ist the code completion stuff. As far as I know, NRefactory 5 provides everything that is required to provide code completion (parser, type system etc.) but I just can't figure out how to use it. I took a look at SharpDevelop source code but they don't use NRefactory 5 for code completion there, they only use it as decompiler. As I couldn't find an example on how to use it for code completion in the net as well I thought that I might find some help here.
The situation is as follows. I have one single file containing the script code. Actually it is not even a file but a string which I get from the editor control (by the way: I'm using AvalonEdit for this. Great editor!) and some assemblies that needs to get referenced. So, no solution files, no project files etc. just one string of source code and the assemblies.
I've taken a look at the Demo that comes with NRefactory 5 and the article on code project and got up with something like this:
var unresolvedTypeSystem = syntaxTree.ToTypeSystem();
IProjectContent pc = new CSharpProjectContent();
// Add parsed files to the type system
pc = pc.AddOrUpdateFiles(unresolvedTypeSystem);
// Add referenced assemblies:
pc = pc.AddAssemblyReferences(new CecilLoader().LoadAssemblyFile(
System.Reflection.Assembly.GetAssembly(typeof(Object)).Location));
My problem is that I have no clue on how to go on. I'm not even sure if it is the right approach to accomplish my goal. How to use the CSharpCompletionEngine? What else is required? etc. You see there are many things that are very unclear at the moment and I hope you can bring some light into this.
Thank you all very much in advance!

I've just compiled and example project that does C# code completion with AvalonEdit and NRefactory.
It can be found on Github here.

Take a look at method ICSharpCode.NRefactory.CSharp.CodeCompletion.CreateEngine. You need to create an instance of CSharpCompletionEngine and pass in the correct document and the resolvers. I managed to get it working for CTRL+Space compltition scenario. However I am having troubles with references to types that are in other namespaces. It looks like CSharpTypeResolveContext does not take into account the using namespace statements - If I resolve the references with CSharpAstResolver, they are resolved OK, but I am unable to correctly use this resolver in code completition scenario...
UPDATE #1:
I've just managed to get the working by obtaining resolver from unresolved fail.
Here is the snippet:
var mb = new DefaultCompletionContextProvider(doc, unresolvedFile);
var resolver3 = unresolvedFile.GetResolver(cmp, loc); // get the resolver from unresolvedFile
var engine = new CSharpCompletionEngine(doc, mb, new CodeCompletionBugTests.TestFactory(resolver3), pctx, resolver3.CurrentTypeResolveContext );
Update #2:
Here is the complete method. It references classes from unit test projects, sou you would need to reference/copy them into your project:
public static IEnumerable<ICompletionData> DoCodeComplete(string editorText, int offset) // not the best way to put in the whole string every time
{
var doc = new ReadOnlyDocument(editorText);
var location = doc.GetLocation(offset);
string parsedText = editorText; // TODO: Why there are different values in test cases?
var syntaxTree = new CSharpParser().Parse(parsedText, "program.cs");
syntaxTree.Freeze();
var unresolvedFile = syntaxTree.ToTypeSystem();
var mb = new DefaultCompletionContextProvider(doc, unresolvedFile);
IProjectContent pctx = new CSharpProjectContent();
var refs = new List<IUnresolvedAssembly> { mscorlib.Value, systemCore.Value, systemAssembly.Value};
pctx = pctx.AddAssemblyReferences(refs);
pctx = pctx.AddOrUpdateFiles(unresolvedFile);
var cmp = pctx.CreateCompilation();
var resolver3 = unresolvedFile.GetResolver(cmp, location);
var engine = new CSharpCompletionEngine(doc, mb, new CodeCompletionBugTests.TestFactory(resolver3), pctx, resolver3.CurrentTypeResolveContext );
engine.EolMarker = Environment.NewLine;
engine.FormattingPolicy = FormattingOptionsFactory.CreateMono();
var data = engine.GetCompletionData(offset, controlSpace: false);
return data;
}
}
Hope it helps,

NRefactory 5 is being used in SharpDevelop 5. The source code for SharpDevelop 5 is currently available in the newNR branch on github. I would take a look at the CSharpCompletionBinding class which has code to display a completion list window using information from NRefactory's CSharpCompletionEngine.

How do I get latest clearcase label programmatically from C#?

I am trying to put version information to my C# GUI framework retrieved from the latest ClearCase label. This was originally done from Visual Soursafe as below.
vssDB = new VSSDatabaseClass();
vssDB.Open( databaseName, "vssadmin", "vssadmin" );
VSSItem item = vssDB.get_VSSItem( #"$\BuildDCP.bat", false );
foreach(VSSVersion vssVersion in item.get_Versions(0))
{
// Pull the first non-blank label and use that
if ( vssVersion.Label != "" )
{
labelID = vssVersion.Label.ToString();
break;
}
}
I am trying to do something similar using ClearCase since we changed our source code control from VSS to CC. Any help would be greatly appreciated.
Thanks!

I believe this could be better achieved through a script, which would be called from your C# program.
But you may be able to directly call some COM objects, through the CAL interface provided with ClearCase.
The documentation for the interface can be accessed through ClearCase help (Start>Programs>Rational ClearCase>ClearCase Help), where there's an entry for "ClearCase Automation Library (CAL)". An alternate path is to look in the ClearCase/bin directory for "cc_cal.chm".
In VB, with CAL API, that would give something like:
Dim CC As New ClearCase.Application
Dim labelID As String
Set aVersion = CC.Version("[Path-To]\BuildDCP.bat");
Set someLabels = Ver.Labels;
If (someLabels.Count > 0) Then
' the first label listed is the most recently applied
labelID = someLabels.Item(1).Type.Name
EndIf

I really wish that the COM interfaces had better documentation, or were more obvious. Or that the code to ClearCase Explorer or Project Explorer were open source.
I've done a few cool things, but I pretty much started by adding COM references to my C# project, and then started screwing around with the interfaces I found.
Good luck!
