I have a VB based block of code I need to rewrite in C# and I'm writing a function which creates an instance of a COM object and creates a new terminal session, goes out, reads a screen and returns the contents of the screen. Right now though I feel like I'm not taking the right approach in C# and would appreciate some feedback.
VB Code
set bzlipi = CreateObject("BlueZone.LIPI")
bzlipi.Username = "myuserid"
bzlipi.Password = "mypassword"
bzlipi.HostAddress = "101.122.0.138"
bzlipi.ShowTransferStatusWindow = False
bzlipi.LocalPromptBeforeOverwrite = False
result = bzlipi.ReceiveFile( "local.txt", "MYLIB/F4101" )
MsgBox bzlipi.ErrorMessage
C#
using BZLIPILib;
using BZWHLLLib;
public void Connector() {
object Host = Activator.CreateInstance(Type.GetType("BZLIPILib.LIPI"));
//Set Host properties
}
As it stands, this is not not recognizing any properties within Host as its
VB counterpart does above. I've made all the available COM object
references within package manager of my VS project. What should I be
doing differently?
Change:
using BZLIPILib;
using BZWHLLLib;
...
object Host = Activator.CreateInstance(Type.GetType("BZLIPILib.LIPI"));
...to:
using BZLIPILib;
using BZWHLLLib;
...
LIPI Host = new LIPI();
...then intellisense will work as expected.
Update: It appears that the actual code required is:
using BZLIPILib;
using BZWHLLLib;
...
LipiObj Host = new LipiObj();
...as per OP's comment below.

I'm trying to update SDMPackageXML property of an AppModel application through C# code. SDMPackageXML is an XML property. I've to update only one node named AutoInstall in the
SDMPackageXML XML property. Here is my code:
ObjectGetOptions opt = new ObjectGetOptions(null, System.TimeSpan.MaxValue, true);
var path = new ManagementPath("SMS_Application.CI_ID=16777568");
ManagementObject obj = new ManagementObject(scope, path, opt);
obj.Get();
foreach (PropertyData property in obj.Properties)
{
if (property.Name == "SDMPackageXML")
{
//change the property value. Set AutoInstall to true
XmlDocument xml = new XmlDocument();
xml.LoadXml(property.Value.ToString());
var autoInstallTag = xml.GetElementsByTagName("AutoInstall");
autoInstallTag[0].InnerText = "false";
property.Value = xml.OuterXml;
}
}
obj.Put();
The problem is that obj.Put(); updates nothing on the SCCM server. Can someone help me please?
So similar to what I talked about in this answer the main problem here is that Microsoft uses a special method to serialize their XML. The deserialization still works with using the default classes but to serialize again there is no documentation as to how to (I'm pretty sure it is possible but I am not knowledgeable enough to do it)
Instead of documentation they provide wrapper classes for this which are shipped with the SCCM Console (Located in the bin directory of the Installation folder of the Console).
In this case this would be Microsoft.ConfigurationManagement.ApplicationManagement.dll. Unlike in powershell where the dependencies in the same path seem to be loaded as well you seem also to have to reference at least Microsoft.ConfigurationManagement.ApplicationManagement.TaskSequenceInstaller.dll as well.
There are also further dlls with names like Microsoft.ConfigurationManagement.ApplicationManagement.MsiInstaller.dll present however at least in my tests the two above were the only ones needed, but if you notice the deserialization failing with "InvalidPropertyException" errors you might need the dll matching your specific application type.
With those two dlls referenced you can write something like this (note I deserialized using the dll as well because why not if it is already loaded and it creates a nice application object to directly modify the properties. This is however technically not necessary. You could deserialize like in your example and only use the serialization part.
ManagementObject obj = new ManagementObject(#"\\<siteserver>\root\SMS\site_<sitecode>:SMS_Application.CI_ID=<id>");
Microsoft.ConfigurationManagement.ApplicationManagement.Application app = Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer.DeserializeFromString(obj["SDMPackageXML"].ToString(), true);
app.AutoInstall = true;
obj["SDMPackageXML"] = Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer.SerializeToString(app, true);
obj.Put();
Now one thing to keep in mind is that is can be a little tricky referencing the applications by their CI_ID because if you update the application the id for the currently valid version of the app changes (the old id still can be used to reference the older revision). So if you change the application gotten using the ID and then change it back with the same ID it will look like only the first change worked. I don't know if this is problematic for you (If you just get all IDs then change every application only once it should not matter) but if it does you can search for the application using their name plus isLatest = 'true' in the WQL query to always get the current one.
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
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.
My plan:
I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window.
Current situation: [fixed... see Update2]
I have already included all python-modules needed, but im still getting a
Library 'GL' not found
it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour.
Requirement:
The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way.
My question:
Is there a certain workaround for my problem or a fix for the library-folder missmatch.
Have read some articles about Tao-Opengl and OpenTK but can't find a good solution.
Update1:
Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated.
SampleCode C#:
ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null);
ScriptRuntime runtime = new ScriptRuntime(setup);
ScriptEngine engine = Python.GetEngine(runtime);
ScriptSource source = engine.CreateScriptSourceFromFile("test.py");
ScriptScope scope = engine.CreateScope();
source.Execute(scope);
SampleCode Python (test.py):
from nodebox.graphics import *
from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle
flock = Flock(50, x=-50, y=-50, width=700, height=400)
flock.sight(80)
def draw(canvas):
canvas.clear()
flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True)
for boid in flock:
push()
translate(boid.x, boid.y)
scale(0.5 + boid.depth)
rotate(boid.heading)
arrow(0, 0, 15)
pop()
canvas.size = 600, 300
def main(canvas):
canvas.run(draw)
Update2:
Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line:
from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL
Now the following Error:
'module' object has no attribute '_getframe'
Kind of a pain to fix it. Updating with results...
Update3:
Fixed by adding following line right after first line in C#-Code:
setup.Options["Frames"] = true;
Current Problem:
No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!
Update4:
Fixed by surfing: link text and adding unicodedata.py and '.pyd to C# Projectfolder.
Current Problem:
'libGL.so not found'... guys.. im almost giving up on nodebox for C#.. to be continued
Update5:
i gave up :/ workaround: c# communicating with nodebox over xml and filesystemwatchers. Not optimal, but case solved.
-X:Frames enables the frames option as runtime (it slows code down a little to have access to the Python frames all the time).
To enable frames when hosting you just need to do:
ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(new Dictionary<string, object>() {
{ "Frames", true }
});
Instead of the null that you're passing now. That's just creating a new dictionary for the options dictionary w/ the contents "Frames" set to true. You can set other options in there as well and in general the -X:Name option is the same here as it is for the command line.
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!
