To answer this we need to know the type of SP_GlobalSearch.JsonObject. If it's something like a InspectionResult class or even a dynamic, then it's simple:

var response = t==null? null : t.Select(r=>{r.InspectionItems.Violations = null; return r;}).ToList();
 //                   purists will hate this ^^^^

If JsonObject is a System.Object, then things get messy. Best to change than to one of the options given above.

Is there any good C# desktop library to implement Card liked UI dashboard?

I have been away from Windows desktop development environment (Using C++ MFC) for many years.

Recently, I plan to port an Android app to Windows desktop environment.

I plan to use C# as my tech stack.

However, I have 0 clue on how to develop a

- Card liked UI dashboard
- Achieve drag-n-move animation

Our Android app looks like - Drag and move animation - YouTube[^]

Do you have any suggestion library, which can help me to implement so?

Thank you.

I am not sure what you mean by "Card liked UI dashboard", but drag and drop is fully supported in .NET: Walkthrough: Perform a drag-and-drop operation - Windows Forms | Microsoft Docs[^].

In the video, it shows how "Card liked UI dashboard" look like.

Also, this is a JavaScript implementation of "Card liked UI dashboard" - Column grid demo[^]

As you can see, the JavaScript example supports drag-n-move, and resizing.

Any idea on where I can get an equivalent C# desktop library to implement such?

Thanks.

Hello Everyone,

I'm currently trying to fetch data from 1 excel workbook, which is having multiple sheets

Please find my excel sheet: here

Please find my code to get the excel data

<pre>public static T GetAllTestData<T>(string keyName)
        {
            using (var connection = new
                          OdbcConnection(TestDataFileConnection()))
            {
                connection.Open();
                System.Data.DataTable dt = null;
                dt = connection.GetSchema(OdbcMetaDataCollectionNames.Tables, null);
                String[] excelSheets = new String[dt.Rows.Count];
                var i = 0;
                // Add the sheet name to the string array.
                foreach (DataRow row in dt.Rows)
                {
                    excelSheets[i] = row["TABLE_NAME"].ToString();
                    i++;
                }
                T value = default(T);
                // Loop through all of the sheets if you want to...
                for (int j = 0; j < excelSheets.Length; j++)
                {
                    // Query each excel sheet.
                    var query = string.Format("select * from [{0}] where TestName = '{1}'", excelSheets[j], keyName);
                    value = connection.Query<T>(query).FirstOrDefault();
                }
                //Console.Write(list1);
                connection.Close();
                return value;
            }
        }

Call to the function:

var param1 = AccessExcelData.GetAllTestData<TestDataModel>("Test1");

Issue:

I want to get all the values from all the sheets in excel which has TestName as "Test1" but in my method, variable value keep getting override which makes it tough for me to get all the values

Can someone look into this, or If I can have another approach for handling excel data test in c#

Your problem is in the following loop ...

for (int j = 0; j < excelSheets.Length; j++)
{
    // Query each excel sheet.
    var query = string.Format("select * from [{0}] where TestName = '{1}'", excelSheets[j], keyName);
    value = connection.Query<T>(query).FirstOrDefault();
}

As soon as you have got a value in the value field, you move on to the next sheet. You need to either do something with the value before going round the next iteration of the loop or store the values (one per sheet) e.g. in an array, and then process them all together after completing the loop.

The timer's Elapsed event will fire on a background thread. You can't update UI controls from a non-UI thread.

If this is a Windows Forms application, use the Windows Forms timer:

For WPF, use the DispatcherTimer:

Hello,

I wanted to recover data from an oracle 9i database. I work on 64 bit systems.

I downloaded the driver ODAC112040Xcopy_64bit in which I found .dlls (among which there is Oracle.DataAccess.dll) that I added them to a windows console application under visual studio 2012 and I added Oracle. DataAccess.dll as a reference in the application. So it works for recovery.

Now, I wanted to create a web service to do this recovery.

So, I created a project of type "ASP.NET Empty Web Application" for I added an element of type web service just that displays by default "Hello Wrold". When I compile and run the application then I get the following message:

Bonjour,

Je voulais récupérer des données à partir d'une base des données oracle 9i. Je travail sur des systèmes de 64 bit.

J'ai téléchargé le driver ODAC112040Xcopy_64bit dans lequel j'ai trouvé des .dll (parmi lequel il y a Oracle.DataAccess.dll) que j'ai les ajouté à une application windows console sous visual studio 2012 et j'ai ajouté Oracle.DataAccess.dll comme référence dans l'application. Alors ça marche pour la récupération.

Maintenant, je voulais créer un web service pour faire cette récupération.

Alors, j'ai crée un projet de type "ASP.NET Empty Web Application" pour j'ai ajouté un élément de type web service juste que affiche par défaut "Hello Wrold". Lorsque je compile et j’exécute l'application alors j'ai le message suivant :

This is an English language site, and we can only answer questions posted in that language. Please use Google Translate to convert your message before posting in future.

But the error message is pretty clear:

Unable to load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load an incorrect format program.

At a guess, the Oracle DB engine is missing (or at least partially missing), configured for 32 bit when the system is 64, or vice versa, etc. Eitehr way, this isn;t somethign we can really help you with.

Start by contacting your hosting service and ask them if they have had this problem before - they may be able to shortcut the process of working out exactly what you have done.

Il s'agit d'un site en anglais et nous ne pouvons répondre qu'aux questions publiées dans cette langue. Veuillez utiliser Google Translate pour convertir votre message avant de poster à l'avenir.

Mais le message d'erreur est assez clair:

Impossible de charger le fichier ou l'assembly 'Oracle.DataAccess' ou l'une de ses dépendances. Une tentative de chargement d'un programme au format incorrect a été effectuée.

À une supposition, le moteur Oracle DB est manquant (ou au moins partiellement manquant), configuré pour 32 bits lorsque le système est à 64, ou vice versa, etc. De toute façon, ce n'est pas le cas, nous pouvons vraiment vous aider.

Commencez par contacter votre service d'hébergement et demandez-leur s'ils ont déjà rencontré ce problème - ils pourront peut-être raccourcir le processus d'élaboration de ce que vous avez fait.

When you get a BadImageFormat exception, it usually means you're trying to mix 32 and 64-bit code in the same process.

From your description, you are probably trying to use a 64-bit .DLL in a 32-bit app, or your code is running as 32-bit instead of 64.

Bonjour,

le driver Oracle Data Access de version 64 bits

Lorsque je crée un application console çà marche pour le driver.
Lorsque je crée une application web asp.net alors le driver ne fonctionne. Les propriétés de cette application :
- target framework 4.0
- Platform target : any CPU
J'ai changé "any cpu" par "X86" mais le même problème puis avec "X64" aussi le même problème

- le web : J'ai coché l'option "use Visual Studio Development Server"
au lieu de "use Local IIS Web Serve"

- the web: I checked the option "use Visual Studio Development Server"
instead of "use Local IIS Web Serve"

A console app is not an ASP.NET app. They work in completely different ways.

A platform target of "AnyCPU" runs, by default either as the CPU architecture on older versions of .NET or as a 32-bit app.

Changing the platform target to "X86" forces the app to run as 32-bit only, even on a 64-bit machine.

Change the target to x64 to match the architecture of the .DLL's you're using. In IIS, in the Application Pool you are running your code under, under Advanced Options, there is an option to run the app as a 32-bit app instead of 64-bit. If that setting is turned on, your code will run as 32-bit instead of 64-bit.

Also, you MUST install the Oracle Client on the IIS server in order for Oracle database access to work.

Uhhh... I just got done telling you that x86 means "32-bit" and running 32-bit code in the App Pool is turned OFF. Change the platform target back to x64.

Now, if you're deploying just a single Oracle .DLL with your app, you're definitely doing it wrong. Oracle requires and entire Client installation in order to work. Just deploying one of two .DLL's with Oracle in the name will NOT WORK.

J'ai téléchargé le dossier .zip ODAC112040Xcopy_32bit et ODAC112040Xcopy_64bit
Est ce que je dois utiliser ODAC 32bit ou bien ODAC 64bit ?

Ce dossier contient plusieurs types de dll
alors quel(s) .dll à ajouter dans mon projet ?

You're doing this all wrong. You don't just add a .DLL to your project. Oracle does not work that way. Forget what you downloaded.

You have to install the Oracle Client and add ODP.NET to your project through the Nuget Package Manager under the Tools menu in Visual Studio. In NPM, search for "ODP.NET4" and add that to your project.

When deploying your application to a server, that server must also have the Oracle Client installed else your application will not work.

Actually, the XCopy installation of Oracle client should work if you add all the files to the bin folder.
But only if you don't have another installation with another bitness.

J'ai téléchargé "ODAC112040Xcopy_32bit" et j'ai copié les .dll necessaires dans mon projet et j'ai ajouté le driver "Oracle.DataAccess.dll" dans la partie reference de mon projet. J'ai target platform avec 32 bit.
Après compilation et exécution, alors le driver a été bien chargé mais je ne peux pas connecter au base oracle sachant que de version 9i et lire le contenu d'une table.
J'ai le message suivant :

System.TypeInitializationException: Une exception a été levée par l'initialiseur de type pour 'Oracle.DataAccess.Client.OracleConnection'. ---> Oracle.DataAccess.Client.OracleException: The provider is not compatible with the version of Oracle client
   à Oracle.DataAccess.Client.OracleInit.Initialize()
   à Oracle.DataAccess.Client.OracleConnection..cctor()
   --- Fin de la trace de la pile d'exception interne ---
   à Oracle.DataAccess.Client.OracleConnection..ctor(String connectionString)
   à WebServiceToBD.Service1.view_data() dans d:\Developpement\SiteVs2012\WebServiceToBD\Service1.asmx.cs:ligne 48

Voici le code de méthode :

  public DataTable view_data()
        {
            OracleConnection conn = new OracleConnection("Data Source=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = *.*.*.*)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = ***)));User ID=***;Password=***");
            conn.Open();
            OracleDataAdapter dr = new OracleDataAdapter("select * from Personne", conn);
            DataSet ds = new DataSet();
            ds.Tables.Add("Personne");
            dr.Fill(ds,"Personne");
            DataTable tt = ds.Tables[0];
            return tt;
        }
<pre lang="c#">

La ligne 48 correspond au code suivant :

<pre lang="c#">OracleConnection conn = new OracleConnection("Data Source=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = *.*.*.*)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = ***)));User ID=***;Password=***");

Cette chaîne de connexion existe dans le programme et pas dans le fichier "Web.config".

When you are using unmanaged code (the Oracle Client in this case), EVERYTHING need to have the same bitness (32 or 64 bits), including the client, debugger, IIS Application pool and the VSHost.exe.

More info on that here: Visual Studio Debugging and 64 Bit .NET Applications - Rick Strahl's Web Log[^]

In this case I'm not even sure if you have the same bitness on the Oracle.DataAccess.dll and the rest of the client files.
You can use corflags.exe to determine bitness of an .exe

Thanks it works for the driver.

I used this driver in a .net web service. Then I will call this web service in another asp net project. The web service call and the data recovery work on a table with a reduced number of lines.

Now, I wanted to retrieve the contents of a table that contains 1844 rows and 58 columns.
After compilation and execution, I have the following message:

Server error in application '/'.
The maximum size quota allowed for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.
Description: An unhandled exception occurred during the execution of the current web request. Check the stack trace for more information on the error and its origin in the code.

Exception details: System.ServiceModel.QuotaExceededException: The maximum size quota allowed for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.
