How to make Generated gif in xamarin.ios slower?

I created a service used in my xamarin.forms project to generate a gif from four downloaded frame. The android side is working good, but I got a problem in iOs side, where gif is created but it's too fast, regardless of the set delay value. This is my class:
public class GifService : IGifService
{
public string CreateGif(string frame1Path, string frame2Path, string frame3Path, string frame4Path,string webId,string path="")
{
List<UIImage> listOfFrame = new List<UIImage>();
UIImage image1 = new UIImage(frame1Path);
listOfFrame.Add(image1);
UIImage image2 = new UIImage(frame2Path);
listOfFrame.Add(image2);
UIImage image3 = new UIImage(frame3Path);
listOfFrame.Add(image3);
UIImage image4 = new UIImage(frame4Path);
listOfFrame.Add(image4);
NSMutableDictionary fileProperties = new NSMutableDictionary();
fileProperties.Add(CGImageProperties.GIFLoopCount, new NSNumber(0));
NSMutableDictionary frameProperties = new NSMutableDictionary();
frameProperties.Add(CGImageProperties.GIFDelayTime, new NSNumber(5f));
NSUrl documentsDirectoryUrl = NSFileManager.DefaultManager.GetUrl(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomain.User,null, true,out _);
NSUrl fileUrl = documentsDirectoryUrl.Append(webId + ".gif",false);
var destination = CGImageDestination.Create(fileUrl, MobileCoreServices.UTType.GIF, 4);
destination.SetProperties(fileProperties);
foreach(var frame in listOfFrame)
{
var cgImage = frame.CGImage;
if(cgImage!= null)
{
destination.AddImage(cgImage, frameProperties);
}
}
if (!destination.Close())
{
Console.WriteLine("Failed to finalize the image destination");
}
return fileUrl.Path;
}
}
I think that the problem is CGImageProperties.GIFDelayTime that is ignored, but i don't know why. How can I resolve this problem?

After some tries, I found finally a solution to generate a gif with a desired delay. I don't know why, but in the way i showed in my question, the options are ignored.
Here a working solution:
public class GifService : IGifService
{
public string CreateGif(string frame1Path, string frame2Path, string frame3Path, string frame4Path,string webId,string path="")
{
List<UIImage> listOfFrame = new List<UIImage>();
UIImage image1 = new UIImage(frame1Path);
listOfFrame.Add(image1);
UIImage image2 = new UIImage(frame2Path);
listOfFrame.Add(image2);
UIImage image3 = new UIImage(frame3Path);
listOfFrame.Add(image3);
UIImage image4 = new UIImage(frame4Path);
listOfFrame.Add(image4);
NSMutableDictionary fileProperties = new NSMutableDictionary
{
{ CGImageProperties.GIFLoopCount, new NSNumber(1) }
};
NSUrl documentsDirectoryUrl = NSFileManager.DefaultManager.GetUrl(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomain.User,null, true,out _);
NSUrl fileUrl = documentsDirectoryUrl.Append(webId + ".gif",false);
var destination = CGImageDestination.Create(fileUrl, MobileCoreServices.UTType.GIF, 4);
destination.SetProperties(fileProperties);
foreach (var frame in listOfFrame)
{
//difference is here, i create a var option and i set the
//GifDictionary
var options = new CGImageDestinationOptions();
options.GifDictionary = new NSMutableDictionary();
options.GifDictionary[CGImageProperties.GIFDelayTime] = new NSNumber(1f);
var cgImage = frame.CGImage;
if(cgImage!= null)
{
destination.AddImage(cgImage, options);
}
}
if (!destination.Close())
{
Console.WriteLine("Failed to finalize the image destination");
}
return fileUrl.Path;
}
}

acumatica import items with image API

Now I have successfully working code (with multiple threads) for items bulk import in IN202500 screen in Acumatica.
The problem is that I am struggling to import an image of an item and actually I don't have an image by itself but only URL link to this image.
So, my question is has anyone done this in c#?
This is my piece of code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ItemImportMultiThreaded
{
public class ItemImporter
{
private IN202500.Screen _itemsScreen;
private static object _itemsSchemaLock = new object();
private static IN202500.Content _itemsSchema;
public void Login(string url, string username, string password, string company)
{
Console.WriteLine("[{0}] Logging in to {1}...", System.Threading.Thread.CurrentThread.ManagedThreadId, url);
_itemsScreen = new IN202500.Screen();
_itemsScreen.Url = url + "/PMSDB/(W(2))/Soap/IN202500.asmx";
_itemsScreen.EnableDecompression = true;
_itemsScreen.CookieContainer = new System.Net.CookieContainer();
_itemsScreen.Timeout = 36000;
_itemsScreen.Login(username, password);
Console.WriteLine("[{0}] Logged in to {1}.", System.Threading.Thread.CurrentThread.ManagedThreadId, url);
lock (_itemsSchemaLock)
{
// Threads can share the same schema.
if (_itemsSchema == null)
{
Console.WriteLine("[{0}] Retrieving IN202500 schema...", System.Threading.Thread.CurrentThread.ManagedThreadId);
_itemsSchema = _itemsScreen.GetSchema();
if (_itemsSchema == null) throw new Exception("IN202500 GetSchema returned null. See AC-73433.");
}
}
}
public void Logout()
{
_itemsScreen.Logout();
}
public void Import(List<Item> items)
{
Console.WriteLine("[{0}] Submitting {1} items to Acumatica...", System.Threading.Thread.CurrentThread.ManagedThreadId, items.Count);
var commands = new IN202500.Command[]
{
_itemsSchema.StockItemSummary.InventoryID,
_itemsSchema.StockItemSummary.Description,
_itemsSchema.GeneralSettingsItemDefaults.ItemClass,
_itemsSchema.VendorDetails.VendorID,
_itemsSchema.VendorDetails.VendorInventoryID,
_itemsSchema.VendorDetails.ServiceCommands.NewRow,
_itemsSchema.VendorDetails.VendorID,
_itemsSchema.VendorDetails.VendorInventoryID,
_itemsSchema.VendorDetails.ServiceCommands.NewRow,
_itemsSchema.VendorDetails.VendorID,
_itemsSchema.VendorDetails.VendorInventoryID,
_itemsSchema.CrossReference.AlternateID,
_itemsSchema.CrossReference.Description,
_itemsSchema.Actions.Save
};
string[][] data = new string[items.Count][];
int count = 0;
foreach(Item item in items)
{
data[count] = new string[11];
data[count][0] = item.InventoryID;
data[count][1] = item.Description.Trim();
data[count][2] = item.ItemClassID;
data[count][3] = item.DigiKey;
data[count][4] = item.DKPN;
data[count][5] = item.Mouser;
data[count][6] = item.MouserID;
data[count][7] = item.Element14;
data[count][8] = item.Element14ID;
data[count][9] = item.AlternateID;
data[count][10] = item.Descr;
count++;
}
_itemsScreen.Import(commands, null, data, false, true, true);
Console.WriteLine("[{0}] Submitted {1} items to Acumatica.", System.Threading.Thread.CurrentThread.ManagedThreadId, items.Count);
}
}
}
I tried to use FileStream but that didn't work.

If by URL link you mean an external http resource, you can download the image and upload it.
The StockItems image field cycle through all the images contained in the Files popup in the order they are displayed:
I uploaded the images from a static external Url using the following code:
const string imageUrl = "https://cdn.acumatica.com/media/2016/03/software-technology-industries-small.jpg";
string path = Path.Combine(Path.GetTempPath(), Path.ChangeExtension(Path.GetTempFileName(), ".jpg"));
// Download Image
using (WebClient client = new WebClient())
{
client.DownloadFile(new Uri(imageUrl), path);
}
// ReadUploadFile function below
byte[] data = ReadUploadFile(path);
_itemsScreen.Import(new IN202500.Command[]
{
// Get Inventory Item
new Value
{
Value = "D1",
LinkedCommand = _itemsSchema.StockItemSummary.InventoryID,
},
_itemsSchema.Actions.Save,
// Upload Inventory Item Image
new Value
{
FieldName = Path.GetFileName(path),
LinkedCommand = _itemsSchema.StockItemSummary.ServiceCommands.Attachment
},
_itemsSchema.Actions.Save
},
null,
new string[][]
{
new string[]
{
// Image data
Convert.ToBase64String(data)
}
},
false,
false,
true);
public byte[] ReadUploadFile(string filePath)
{
byte[] filedata;
using (FileStream file = File.Open(filePath,
FileMode.Open,
FileAccess.ReadWrite,
FileShare.ReadWrite))
{
filedata = new byte[file.Length];
file.Read(filedata, 0, filedata.Length);
}
if (filedata == null || filedata.Length == 0)
{
throw new Exception(string.Concat("Invalid or empty file: ", filePath));
}
return filedata;
}

You can try using the below, Tested Code.
var content = _context.CR306000GetSchema(); _context.CR306000Clear();
var commands = new List();
ReqParameter(content, ref commands);
commands.Add(content.Actions.Save);
commands.Add(content.CaseSummary.CaseID);
var orderResults = _context.CR306000Submit(commands.ToArray());
private static void ReqParameter(CR306000Content content, ref List cmds) { if (cmds == null) throw new ArgumentNullException("cmds");
private static void ReqParameter(CR306000Content content, ref List<Command> cmds)
{
if (cmds == null) throw new ArgumentNullException("cmds");
byte[] filedata= null;
Uri uri = new Uri("https://cdn.acumatica.com/media/2016/03/software-technology-industries-small.jpg"); // change the required url of the data that has to be fetched
if (uri.IsFile)
{
string filename = System.IO.Path.GetFileName(uri.LocalPath);
filedata = System.Text.Encoding.UTF8.GetBytes(uri.LocalPath);
}
if (filedata == null)
{
WebClient wc = new WebClient();
filedata = wc.DownloadData(uri);
}
cmds = new List<Command>
{
//Case Header Details
new Value { Value="<NEW>",LinkedCommand = content.CaseSummary.CaseID},
new Value { Value="L41",LinkedCommand = content.CaseSummary.ClassID},
new Value { Value="ABCSTUDIOS",LinkedCommand = content.CaseSummary.BusinessAccount, Commit = true},
new Value { Value="Test subject created from envelop call 11C",LinkedCommand = content.CaseSummary.Subject},
// body of the case
new Value{Value= "Body of the content for created through envelop call 11B", LinkedCommand = content.Details.Description},
//Attaching a file
new Value
{
Value = Convert.ToBase64String(filedata), // byte data that is passed to through envelop
FieldName = "Test.jpg",
LinkedCommand =
content.CaseSummary.ServiceCommands.Attachment
},
};
}
Let me know if this works for you.
Thanks

How to Upload document in acumatica screen using acumatica web service

I am new to using acumatica web service. is it possible to upload a document/ file in specific screen as attachment like business account attachment.
eg. below screen in which we add manually.

I find the solution and posted to help anyone.
To upload any file we must convert that file into bytes and submit bytes which convert your file.
//Get bytes of file
byte[] filedata;
using(System.IO.FileStream file =
System.IO.File.Open(#"D:\Test.pdf",System.IO.FileMode.Open))
{
filedata = new byte[file.Length];
file.Read(filedata,0,filedata.Length);
}
// Import Data Now to Business Account
BAccount.CR303000ImportResult[] lstObjContent = context.CR303000Import
(
new BAccount.Command[]
{
// Must Pass BusinessAccount in which we want to update or add data
new BAccount.Value { Value="XXXXXX",LinkedCommand=objContent.AccountSummary.BusinessAccount},
new BAccount.Value { Value="TestValue123",LinkedCommand=objContent.AccountSetup.CurrentMethod},
new BAccount.Value { FieldName="NameOfFileWithExtension",LinkedCommand=objContent.AccountSummary.ServiceCommands.Attachment},
objContent.Actions.Save
},null,new string[][] { new string[] { Convert.ToBase64String(filedata) },new string[] { Convert.ToBase64String(filedata) },}
,false,false,true
);

Even the below code works. Verified in version 18R1.
var content = _context.CR306000GetSchema(); _context.CR306000Clear();
var commands = new List();
ReqParameter(content, ref commands);
commands.Add(content.Actions.Save);
commands.Add(content.CaseSummary.CaseID);
var orderResults = _context.CR306000Submit(commands.ToArray());
private static void ReqParameter(CR306000Content content, ref List<Command> cmds)
{
if (cmds == null) throw new ArgumentNullException("cmds");
byte[] filedata= null;
Uri uri = new Uri("https://acmdev.baccahq.com/Icons/login_bg5.jpg"); // change the required url of the data that has to be fetched
if (uri.IsFile)
{
string filename = System.IO.Path.GetFileName(uri.LocalPath);
filedata = System.Text.Encoding.UTF8.GetBytes(uri.LocalPath);
}
if (filedata == null)
{
WebClient wc = new WebClient();
filedata = wc.DownloadData(uri);
}
cmds = new List<Command>
{
//Case Header Details
new Value { Value="<NEW>",LinkedCommand = content.CaseSummary.CaseID},
new Value { Value="L41",LinkedCommand = content.CaseSummary.ClassID},
new Value { Value="ABCSTUDIOS",LinkedCommand = content.CaseSummary.BusinessAccount, Commit = true},
new Value { Value="Test subject created from envelop call 11C",LinkedCommand = content.CaseSummary.Subject},
// body of the case
new Value{Value= "Body of the content for created through envelop call 11B", LinkedCommand = content.Details.Description},
//Attaching a file
new Value
{
Value = Convert.ToBase64String(filedata), // byte data that is passed to through envelop
FieldName = "Test.jpg",
LinkedCommand =
content.CaseSummary.ServiceCommands.Attachment
},
};
}

Is DataGridView wrong choice?

I am new to C# and Windows Forms so please be patient. I am making a Windows Form that lets you load a video, load a script, then makes captions. I want to display a table where the data will be populated automatically as they mark starts and ends of caption and select text and will be editable. At the end I want to save all the data to an xml file. A DataGridView UI-wise seems like exactly what I want, but I can't figure out backend how to get the data out of the DataGridView ( preferably in a dataset).
I am now considering using a ListView with multiple columns instead. Any advice would be greatly appreciated

Datagridview should work just fine for that application and you can easily retrieve any data you save to it by doing:
dgvThing.DataSource;
That will contain whatever type that you have saved into the Datagridview (List, array, etc).
Example:
public class SuperFunObject {
public TimeSpan start { get; set; }
public TimeSpan end { get; set; }
public string selectedText { get; set; }
public SuperFunObject(Timespan a, Timespan b, string text) {
start = a;
end = b;
selectedText = text;
}
}
List<SuperFunObject> funList = new List<SuperFunObject>();
funList.Add(new SuperFunObject(TimeSpan.FromSeconds(0.0),TimeSpan.FromSeconds(20.0),"Hello"));
dgvThing.DataSource = funList;
...
...
//retrive your list
List<SuperFunObject> getData = ((List<SuperFunObject>)dgvThing.DataSource);
I hope the example helps a bit. Side note, the reason for the accessors (get,set) are for the Datagridview to be able to retrieve the data from the object for display.

Here is a little ditty that'll save a class that you populate into an array from your datasource to am XML file path that you specify in the parameter.
public static bool SaveXMLObjectToFile(object IncomingXMLObject, string Path)
{
string xmlString = null;
File TheFileIn = default(File);
string docname = null;
StreamWriter WriteAFile = default(StreamWriter);
string filelocation = null;
//Dim filelocation As String
System.IO.MemoryStream MemStream = new System.IO.MemoryStream();
System.Xml.Serialization.XmlSerializer Ser = default(System.Xml.Serialization.XmlSerializer);
System.Text.Encoding encodingvalue = System.Text.UTF8Encoding.UTF8;
System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(MemStream, encodingvalue);
bool Result = false;
try {
File.Delete(Path);
Ser = new System.Xml.Serialization.XmlSerializer(IncomingXMLObject.GetType);
Ser.Serialize(writer, IncomingXMLObject);
MemStream = writer.BaseStream;
//as system.io.memorystream
xmlString = UTF8ByteArrayToString(MemStream.ToArray());
//Will Not Convert Byte Array from Diagram
filelocation = Path;
WriteAFile = TheFileIn.AppendText(filelocation);
WriteAFile.Write(xmlString);
WriteAFile.Close();
Result = true;
} catch (Exception e) {
Result = false;
}
return Result;
}

iterate through and infoPath form

I have a infopath form that may contain multiple attachments: By using a group of repeating elements, the user can click an “click add item” option he will be able to upload more attachments.
In Sharepoint I am using a workflow to extract the attachments and put them in a separate list. So far I manage only to extract the first one and the workflow finishes successfully.
can I put a loop or something to iterate trough the form?
I attach the code below:
public sealed partial class FileCopyFeature : SharePointSequentialWorkflowActivity
{
public FileCopyFeature()
{
InitializeComponent();
}
public Guid workflowId = default(System.Guid);
public Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties workflowProperties = new Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties();
private void CopyFile(object sender, EventArgs e)
{
// Retrieve the file associated with the item
// on which the workflow has been instantiated
SPFile file = workflowProperties.Item.File;
if (file == null)
return;
// Get the binary data of the file
byte[] xmlFormData = null;
xmlFormData = file.OpenBinary();
// Load the data into an XPathDocument object
XPathDocument ipForm = null;
if (xmlFormData != null)
{
using (MemoryStream ms = new MemoryStream(xmlFormData))
{
ipForm = new XPathDocument(ms);
ms.Close();
}
}
if (ipForm == null)
return;
// Create an XPathNavigator object to navigate the XML

It appears that your issue has to do with your use of MoveToNext. Per the documentation, this function moves to the next sibling, and does not navigate to children elements. Your code appears to go to the first element it finds (presumably my:myFields), looks for the first child named my:field2 (it only pulls the first one since you are using SelectSingleNode, and then goes to the next sibling of my:myFields (not the next sibling of my:field2). One way to fix this might be to replace your current do-while loop with a call to SelectNodes like the following and then iterate over nodeList.
XmlNodeList nodelist = ipFormNav.SelectNodes("//my:field2", nsManager);
