There are multiple ways and libraries available for Consuming TWAIN data source in C# window application but my requirement is to make my application TWAIN ready which will be used as TWAIN data source for calling application.
Please check the TWAIN Specification for more details. It can be downloaded from http://www.twain.org/
The Source
The Source receives operations either from the application, via the Source Manager, or directly from the Source Manager. It processes the request and returns the appropriate Return Code (the codes are prefixed with TWRC_) indicating the results of the operation to the Source Manager. If the originator of the operation was the application, then the Return Code is passed back to the
application as the return value of its DSM_Entry( ) function call. If the operation was unsuccessful, a Condition Code (the codes are prefixed with TWCC_) containing more specific information is set by the Source. Although the Condition Code is set, it is not automatically passed back. The application must invoke an operation to inquire about the contents of the Condition Code.
The implementation of the Source is the same as the implementation of the Source Manager:
On Windows
- The Source is a Dynamic Link Library (DLL) with a .ds extension.
DS_Entry is only called by the Source Manager. Written in C code form, the declaration looks like this:
TW_UINT16 TW_CALLINGSTYLE DS_Entry
( pTW_IDENTITY pOrigin, // source of message
TW_UINT32 DG, // data group ID: DG_xxxx
TW_UINT16 DAT, // data argument type: DAT_xxxx
TW_UINT16 MSG, // message ID: MSG_xxxx
TW_MEMREF pData // pointer to data
);

Failing to raise an azure VM from a marketplace image programatically.
The code:
var linuxVM = await _azure.VirtualMachines.Define(linuxVmName)
.WithRegion(Region)
.WithExistingResourceGroup(rgName)
.WithNewPrimaryNetwork("10.0.0.0/28")
.WithPrimaryPrivateIPAddressDynamic()
.WithoutPrimaryPublicIPAddress()
.WithSpecificLinuxImageVersion(new ImageReference())
.WithRootUsername(userName)
.WithRootPassword(password)
.WithSize(VirtualMachineSizeTypes.StandardNC6sV3)
.WithPlan(new PurchasePlan("nvidia", "ngc-base-version-20-10-1", "ngc_azure_17_11"))
.CreateAsync();
In Azure I've enabled "Want to deploy programmatically? Get started" for the given image (as explained here).
There are several options as to the method that selects the image, not sure which method should be used and with which parameters. Tried several combinations, but all returned misc error messages.
Did not find code samples more detailed this (which does not explain how to use an image from the marketplace).
Edit:
The code above returns this exception:
Microsoft.Rest.Azure.CloudException: 'This resource was created without a plan. A new plan cannot be associated with an update.'
Another attempt with more populated parameters causes the same exception:
.WithSpecificLinuxImageVersion(new ImageReference(new ImageReferenceInner(
publisher: "nvidia",
offer: "ngc_azure_17_11",
sku: "ngc-base-version-20-10-1"
)))
The missing parameter was the image's version. The code to raise the image looks like so:
var vm = await _azure.VirtualMachines.Define(linuxVmName)
.WithRegion(_region)
.WithExistingResourceGroup(_rgName)
.WithNewPrimaryNetwork("10.0.0.0/28")
.WithPrimaryPrivateIPAddressDynamic()
.WithoutPrimaryPublicIPAddress()
.WithSpecificLinuxImageVersion(new ImageReference(new ImageReferenceInner(
publisher: "nvidia",
offer: "ngc_azure_17_11",
sku: "ngc-base-version-20-10-1",
version: "20.10.1"
)))
.WithRootUsername(userName)
.WithRootPassword(password)
.WithSize(VirtualMachineSizeTypes.StandardNC6sV3)
.WithPlan(new PurchasePlan("nvidia", "ngc-base-version-20-10-1", "ngc_azure_17_11"))
.CreateAsync();
The version can be found in the UI:
It's also possible to get all the image's details via CLI:
Get-AzVMImageOffer -Location "West Europe" -PublisherName nvidia

I found out, that the requirements for showing a notification consist of setting a content-title, a context-text and a small icon. The last of which I do not do. Unfortunately, I don't know, how to provide a small icon especially in unity.
Original Question
I'm currently trying to show a notification from a unity-instance via android. I want to show the notification, when the user enters a specific gps-area. Thus, the script should run, when the app is paused. That's why I want to use the android-functionality.
With this code, I currently try to show the notification manually:
public void createNotification(){
NotificationManagerCompat nManager = NotificationManagerCompat.from(curContext);
NotificationCompat.Builder builder = new NotificationCompat.Builder(curContext, CHANNEL_ID)
.setContentTitle("Stuff")
.setContentText("MoreStuff")
.setPriority(NotificationCompat.PRIORITY_DEFAULT);
nManager.notify(1551, builder.build());
}
The context is stored in a static variable and is set, when calling the method.
The function is called in C# with:
PluginInstance.Call("createNotification");
The PluginInstance works, the function can be called, but I get the error:
AndroidJavaException: java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/core/app/NotificationManagerCompat
I found the solution for my problem: I used the Unity Android Jar-Resolver in which I provided the *Dependencies.xml (Where the * presents the Name of my project). In the *Dependenices.xml I specified: <androidPackage spec="androidx.appcompat:appcompat:1.1.0"> and run through the steps, provided in the Tutorial of the Resolver.
Afterwards, multiple dependencies appeared in my /Assets/Plugin/Android-Folder, which were successfully transferred to the app, when building it.
I am currently developing a C# application with SAP NCo 3.
I am wondering if I could invoke BAPI into CUA and this BAPI would pass details to child system.
This field is available through Test Function Module (field "RFC target sys"), but it is unavailable directly in standard BAPIs when accessed from SAP NCo.
In ABAP, devs can use:
call function 'BAPI_USER_CHANGE' destination '<TARGET_SYS>'
Can I use something similar in NCo library?
IRfcFunction rfcs = rfcDest.Repository.CreateFunction("BAPI_USER_CHANGE");
Does anybody know how this could be achieved?
Main intent is to reset user passwords to initial ones through App(BAPI) --> CUA --> ChildSystem
Without direct access into child systems.
Hmm, it looks like you have not yet fully understood the meaning of "RFC target sys".
In SE37 "RFC target sys" you enter the name of an RFC destination, which provides details about in which SAP system you want to execute the function module. These details are then defined in SM59, where you can specify parameters like hostname, system number, client, user, password, language, etc.
In the NCo library you do the same via the Class RfcDestinationManager. Here you define the parameters (hostname, system number, client, user, password, language, etc.) of the target system in which you want to execute the function module.
So the line
"RFC target sys: TARGET_SYS"
in SE37 corresponds to a line like
RfcDestination myDest = RfcDestinationManager.GetDestination("TARGET_SYS");
in your .NET program.
And a line of ABAP code like
call function 'BAPI_USER_CHANGE' destination 'TARGET_SYS'
would then correspond to some .NET code like
RfcDestination targetSys = RfcDestinationManager.GetDestination("TARGET_SYS");
IRfcFunction bapiUserChange = targetSys.Repository.CreateFunction("BAPI_USER_CHANGE");
targetSys.Invoke(bapiUserChange);
Note: setting of the input values and error handling is omitted here.
Ok, so I found out that what I wanted to achieve is not possible with just sapnco.
But, in SAP I created function module, which calls function module and uses DESTINATION 'target_sys' to run in end system. This way I achieved what I wanted. By calling my Z_FUNC_MODULE from sapnco I pass variable target_sys and FN is called in child system of CUA.
Hope this helps to someone.
I have an old excel workbook that I am trying to replace with a c# application. The only bit of functionality that I have not been able to replicate is the code below.
So the code below takes a bloomberg ticker (i.e. "VOD LN") and then with DDEInitiate it loads the bloomberg page.
I have read that C# doesn't support DDE or even if it does it is best avoided. In which case how can I do this via C#?
Public Sub LoadBbergPage(string ticker)
' loads bberg page
Dim strExe As String
Dim channelGP As Long
channelGP = DDEInitiate("Winblp", "BBK")
strExe = "<blp-2><home>" & Strings.Trim(ticker) & "<EQUITY><GO>"
DDEExecute channelGP, strExe
DDETerminate channelGP
End Sub
If you're trying to make it easier for your users to launch data into the terminal, you can use 'B-links'. Access it like any other web link. Below is an example for "IBM US Equity" - replace spaces with %20
https://blinks.bloomberg.com/securities/[ticker]/[function]
https://blinks.bloomberg.com/securities/IBM%20US%20Equity/DES
It will ask the user the first time to allow / remember settings and then should launch to terminal. If there are issues, you can go to https://blinks.bloomberg.com/help. Documentation is available on terminal via DOCS BLINKS<GO> (tons more special syntax)
But if you're trying to do some kind of screen scraping etc via DDE, don't bother; just use the Reference Data API instead: https://www.bloomberg.com/professional/support/api-library/
I really like C# and I am familiar with it, but I also want to use HTML5/JavaScript to manage the UI for my Windows 8 Metro app. So, how can I import and use objects from a library made in C# in the Javascript files?
Example here is the starting JS code for an empty HTML5/JS project...
// For an introduction to the Blank template, see the following documentation:
// http://go.microsoft.com/fwlink/?LinkId=232509
(function () {
"use strict";
var app = WinJS.Application;
app.onactivated = function (eventObject) {
if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) {
if (eventObject.detail.previousExecutionState !== Windows.ApplicationModel.Activation.ApplicationExecutionState.terminated) {
// TODO: This application has been newly launched. Initialize
// your application here.
} else {
// TODO: This application has been reactivated from suspension.
// Restore application state here.
}
WinJS.UI.processAll();
}
};
app.oncheckpoint = function (eventObject) {
// TODO: This application is about to be suspended. Save any state
// that needs to persist across suspensions here. You might use the
// WinJS.Application.sessionState object, which is automatically
// saved and restored across suspension. If you need to complete an
// asynchronous operation before your application is suspended, call
// eventObject.setPromise().
};
app.start();
})();
Can I pull in and use libraries and objects in JS that are written in C#?
I was kind of bummed they appear to segregate C# from HTML5 based projects...
You absolutely can do this. This is the beauty of the Windows 8 and the new application model. There are a lot of places to start and look at.
Start here: http://msdn.microsoft.com/en-us/library/windows/apps/br230301(v=vs.110).aspx You can drill down further in the above link where it also links to a real basic sample. http://msdn.microsoft.com/en-us/library/windows/apps/hh779077(v=vs.110).aspx
In a nutshell, you'll create a metro class library in C# and then set the output type of your C# from a "Class Library" to a WinMD. You can then reference and use that library in your javascript project.
There is a lot of documentation on building metro apps available at http://msdn.microsoft.com/en-us/library/windows/apps
