I am using ELCImagepicker.dll to create gallery with multi image selection. Everything is working fine.
1- I want to change icon of Tick whenever user select. It's very old style
2- Change validation message of maximum selection. I want to use the word "select" instead of "send".
Here is the MediaService file. maxImage set validation of maximum images
public class MediaService : IMediaService
{
public async Task OpenGallery(int maxImage)
{
var picker = ELCImagePickerViewController.Create(maxImage);
picker.MaximumImagesCount = maxImage;
var topController = UIApplication.SharedApplication.KeyWindow.RootViewController;
while (topController.PresentedViewController != null)
{
topController = topController.PresentedViewController;
}
topController.PresentViewController(picker, true, null);
List<string> images = new List<string>();
await picker.Completion.ContinueWith(t =>
{
picker.BeginInvokeOnMainThread(() =>
{
//dismiss the picker
picker.DismissViewController(true, null);
if (t.IsCanceled || t.Exception != null)
{
}
else
{
//List<string> images = new List<string>();
var items = t.Result as List<AssetResult>;
foreach (var item in items)
{
var path = Save(item.Image, item.Name);
images.Add(path);
//CleanPath(path);
}
}
});
});
MessagingCenter.Send<App, List<string>>((App)Xamarin.Forms.Application.Current, "ImagesSelected", images);
}
string Save(UIImage image, string name)
{
var documentsDirectory = Environment.GetFolderPath
(Environment.SpecialFolder.Personal);
string jpgFilename = System.IO.Path.Combine(documentsDirectory, name); // hardcoded filename, overwritten each time
NSData imgData = image.AsJPEG();
NSError err = null;
if (imgData.Save(jpgFilename, false, out err))
{
return jpgFilename;
}
else
{
Console.WriteLine("NOT saved as " + jpgFilename + " because" + err.LocalizedDescription);
return null;
}
}
void IMediaService.ClearFiles(List<string> filePaths)
{
var documentsDirectory = Environment.GetFolderPath
(Environment.SpecialFolder.Personal);
if (Directory.Exists(documentsDirectory))
{
foreach (var p in filePaths)
{
File.Delete(p);
}
}
}
}
Please guide
Since the author hasn't expose the api that can change icon or text,so you have to change them inside the source code, and then create dll for using.

This feels like a simple question and I feel like I am overthinking it. I am doing an AWS project that will compare face(s) on an image to a database (s3bucket) of other faces. So far, I have a lambda function for the comparefacerequest, a class library which invokes the function, and an UWP that inputs the image file and outputs a result. It has worked so far being based on boolean (true or false) functions, but now I want it to instead return what face(s) are recognized via an array. I struggling at implementing this.
Below is my lambda function. I have adjusted the task to be an Array instead of a bool and changed the return to be an array. At the bottom, I have created a global variable class with a testing array so I could attempt to reference the array elsewhere.
public class Function
{
//Function
public async Task<Array> FunctionHandler(string input, ILambdaContext context)
{
//number of matched faces
int matched = 0;
//Client setup
var rekognitionclient = new AmazonRekognitionClient();
var s3client = new AmazonS3Client();
//Create list of target images
ListObjectsRequest list = new ListObjectsRequest
{
BucketName = "bucket2"
};
ListObjectsResponse listre = await s3client.ListObjectsAsync(list);
//loop of list
foreach (Amazon.S3.Model.S3Object obj in listre.S3Objects)
{
//face request with input and obj.key images
var comparefacesrequest = new CompareFacesRequest
{
SourceImage = new Image
{
S3Object = new S3Objects
{
Bucket = "bucket1",
Name = input
}
},
TargetImage = new Image
{
S3Object = new S3Objects
{
Bucket = "bucket2",
Name = obj.Key
}
},
};
//compare with confidence of 95 (subject to change) to current target image
var detectresponse = await rekognitionclient.CompareFacesAsync(comparefacesrequest);
detectresponse.FaceMatches.ForEach(match =>
{
ComparedFace face = match.Face;
if (match.Similarity > 95)
{
//if face detected, raise matched
matched++;
for(int i = 0; i < Globaltest.testingarray.Length; i++)
{
if (Globaltest.testingarray[i] == "test")
{
Globaltest.testingarray[i] = obj.Key;
}
}
}
});
}
//Return true or false depending on if it is matched
if (matched > 0)
{
return Globaltest.testingarray;
}
return Globaltest.testingarray;
}
}
public static class Globaltest
{
public static string[] testingarray = { "test", "test", "test" };
}
Next, is my invoke request in my class library. It has so far been based on the lambda outputting a boolean result, but I thought, "hey, it is parsing the result, it should be fine, right"? I do convert the result to a string, as there is no GetArray, from what I know.
public async Task<bool> IsFace(string filePath, string fileName)
{
await UploadS3(filePath, fileName);
AmazonLambdaClient client = new AmazonLambdaClient(accessKey, secretKey, Amazon.RegionEndpoint.USWest2);
InvokeRequest ir = new InvokeRequest();
ir.InvocationType = InvocationType.RequestResponse;
ir.FunctionName = "ImageTesting";
ir.Payload = "\"" + fileName + "\"";
var result = await client.InvokeAsync(ir);
var strResponse = Encoding.ASCII.GetString(result.Payload.ToArray());
if (bool.TryParse(strResponse, out bool result2))
{
return result2;
}
return false;
}
Finally, here is the section of my UWP where I perform the function. I am referencing the lambda client via "using Lambdaclienttest" (name of lamda project, and this is its only instance I use the reference though). When I run my project, I do still get a face detected when it should, but the Globaltest.testingarray[0] is still equal to "test".
var Facedetector = new FaceDetector(Credentials.accesskey, Credentials.secretkey);
try
{
var result = await Facedetector.IsFace(filepath, filename);
if (result)
{
textBox1.Text = "There is a face detected";
textBox2.Text = Globaltest.testingarray[0];
}
else
{
textBox1.Text = "Try Again";
}
}
catch
{
textBox1.Text = "Please use a photo";
}
Does anyone have any suggestions?
I've got a method that returning back from CompletionService.GetDescriptionAsync(Document, CompletionItem) gives me the following description:
void SQL.GetSQLiteDB(string url) (+ 1 overload)
This is a method I made on a Xamarin project, here are both method signatures:
public static void GetSQLiteDB(string url);
public static string GetSQLiteDB(string url, string name);
What's the Roslyn way to get information on both?
Here's how I'm setting up completions:
async Task InitCodeCompletion()
{
host = MefHostServices.Create(MefHostServices.DefaultAssemblies);
workspace = new AdhocWorkspace(host);
Type[] types =

typeof(object),
typeof(System.Linq.Enumerable),
typeof(System.Collections.IEnumerable),
typeof(Console),
typeof(System.Reflection.Assembly),
typeof(List<>),
typeof(Type),
typeof(SQL)
};
imports = types.Select(x => x.Namespace).Distinct().ToImmutableArray();
assemblies = types.Select(x => x.Assembly).Distinct().ToImmutableArray();
references = assemblies.Select(t => MetadataReference.CreateFromFile(t.Location) as MetadataReference).ToImmutableArray();
compilationOptions = new CSharpCompilationOptions(
OutputKind.DynamicallyLinkedLibrary,
usings: imports);
projectInfo = ProjectInfo.Create(ProjectId.CreateNewId(), VersionStamp.Create(), "Script", "Script", LanguageNames.CSharp, isSubmission: true)

{
string codeModified = "using SQL = XamTestNET5.Services.SQLiteGeneratorService; " + Environment.NewLine;
codeModified += "using HtmlSvc = XamTestNET5.Services.HtmlRetrievalService;" + Environment.NewLine;
// ^^^ The above two lines set up some simple namespace aliases in my project, if you know how to put this in a separate project document and use it in code completion please let me know in comments as otherwise doing so gives me an exception that you can't have multiple syntax trees
codeModified += code;
var source = SourceText.From(codeModified);
document = document.WithText(source);
// cursor position is at the end
var position = source.Length;
var completions = await completionService.GetCompletionsAsync(document, position);
return new CodeCompletionResults() { InputCode = code, ModifiedCode = codeModified, Completions = completions };
}
Here's how I'm getting them now and putting them in a browser control:
private async void CSharpShellEnvironment_EntryCodeCompletionEntry(object sender, CSharpShellEnvironment.EntryEventArgs e)

{
string fText = item.DisplayText.Substring(spanText.Length);

It seems on the surface that CompletionSurface has everything you need, but it doesn't, you need to reference the Document's SemanticModel in order to get all of the signature overloads of a method when the user types ( on a method during code completion.
It wasn't very obvious to me until I started looking through the RoslynPad source, which I recommend doing for a practical example: https://github.com/aelij/RoslynPad
List<IEnumerable<ReferencedSymbol>> allMethodRefs = new List<IEnumerable<ReferencedSymbol>>();
async Task<CodeCompletionResults> GetCompletions(string code)
{
string codeModified = "using SQL = XamTestNET5.Services.SQLiteGeneratorService; " + Environment.NewLine;
codeModified += "using HtmlSvc = XamTestNET5.Services.HtmlRetrievalService;" + Environment.NewLine;
// ^^^ I put my namespace aliases in the same SyntaxTree for now,
// I'd like a better solution though.
codeModified += code;
var source = SourceText.From(codeModified);
document = document.WithText(source);
// cursor position is at the end
var position = source.Length;
var completions = await completionService.GetCompletionsAsync(document, position);
syntaxRoot = await document.GetSyntaxRootAsync();
semanticModel = await document.GetSemanticModelAsync();
var methods = syntaxRoot.DescendantNodes().OfType<InvocationExpressionSyntax>();
allMethodRefs = new List<IEnumerable<ReferencedSymbol>>();
if (methods != null)
{
if (methods.Count() > 0)
{
foreach(var m in methods)
{
var info = semanticModel.GetSymbolInfo(m);
if (info.Symbol != null)
{
allMethodRefs.Add(await SymbolFinder.FindReferencesAsync(info.Symbol, solution));
}
else
{
foreach(var symbol in info.CandidateSymbols)
{
allMethodRefs.Add(await SymbolFinder.FindReferencesAsync(symbol, solution));
}
}
}
}
}
return new CodeCompletionResults() { InputCode = code, ModifiedCode = codeModified, Completions = completions };
}
I encounter a problem when inserting an image in PPTX document.
I want to create a new slide based on slide mask. I used this code to set picture in existing a shape
class Program
{
public static void Run()
{
string dataDir = ConfigurationManager.AppSettings["directoryToSave"];
string srcDir = String.Concat(ConfigurationManager.AppSettings["Source"], "Master.pptx");
string appData = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
//string file = Path.Combine(appData, srcDir);
using (Presentation presentation = new Presentation(srcDir))
{
IMasterLayoutSlideCollection layoutSlides = presentation.Masters[0].LayoutSlides;
ILayoutSlide layoutSlide = null;
foreach (ILayoutSlide titleAndObjectLayoutSlide in layoutSlides)
{
if (titleAndObjectLayoutSlide.Name == "TITRE_CONTENU")
{
layoutSlide = titleAndObjectLayoutSlide;
break;
}
}
string filePath = String.Concat(ConfigurationManager.AppSettings["Source"], #"Logos\bp.png");
Image imgs = (Image)new Bitmap(filePath);
setShapePicture(presentation, layoutSlide, "picture", imgs);
presentation.Slides.InsertEmptySlide(0, layoutSlide);
presentation.Save(dataDir + "AddLayoutSlides_out.pptx", SaveFormat.Pptx);
}
}
public static void setShapePicture(Presentation doc, ILayoutSlide layoutSlide, string shapeName, Image image)
{
var logo_shape = layoutSlide.Shapes.SingleOrDefault(r => r.Name.Equals(shapeName));
IPPImage imgx = doc.Images.AddImage(image);
//Add Picture Frame with height and width equivalent of Picture
logo_shape.FillFormat.FillType = FillType.Picture;
// Set the picture fill mode
logo_shape.FillFormat.PictureFillFormat.PictureFillMode = PictureFillMode.Stretch;
// Set the picture
logo_shape.FillFormat.PictureFillFormat.Picture.Image = imgx;
}
static void Main(string[] args)
{
try
{
var path = ConfigurationManager.AppSettings["sourceAsposeLicensePath"];
License license = new License();
license.SetLicense(path);
Run();
}
catch (Exception ex)
{
Console.WriteLine("Error" + ex.Message);
}
finally
{
Console.WriteLine("Terminated");
Console.ReadKey();
}
}
}
What I get in the generated file is a shape with background picture and a placeholder. You can find all resources in this link MasterSlide+Logos+Output
I have observed the requirements shared by you and like to share that placeholder is not an actual shape but gives a skeleton for shape. I have created a sample code for your convenience that may help you in achieving your requirements.
public static void TestPlaceholderImage()
{
String path = "C:\\Aspose Data\\";
Presentation pres = new Presentation(path + "TestPicture.pptx");
foreach (ISlide slide in pres.Slides)
{
foreach (IShape shape in slide.Shapes)
{
if (shape.Placeholder != null)
{
if (shape.Placeholder.Type == PlaceholderType.Picture)
{
// Instantiate the ImageEx class
System.Drawing.Image img = (System.Drawing.Image)new Bitmap(#"C:\Users\Public\Pictures\Sample Pictures\Desert.jpg");
IPPImage imgx = pres.Images.AddImage(img);
shape.FillFormat.FillType = FillType.Picture;
shape.FillFormat.PictureFillFormat.Picture.Image = imgx;
if (shape is AutoShape)
{
ITextFrame text = ((IAutoShape)shape).TextFrame;
text.Text = " ";
text.Paragraphs[0].ParagraphFormat.Bullet.Type = BulletType.None;
}
}
}
}
}
pres.Save(path + "Addedpic.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
}

I'm trying to get the data from an inline keyboard, I've searched a lot but unfortunately didn't get my answer and non of codes worked for me. Here's my code please help me
static void Main(string[] args){
InlineKeyboardButton[][] buttons =
new InlineKeyboardButton[][]{
new InlineKeyboardButton[]{newInlineKeyboardButton() { Text = "show Channel", CallbackData = "Data1" }},
new InlineKeyboardButton[]{new InlineKeyboardButton() { Text = "show Website", CallbackData = "Data2" }}};
inlineKeyboardMarkup = new InlineKeyboardMarkup() { InlineKeyboard = buttons };
Task.Run(() => RunBot());
Console.ReadLine();
} // End of main method
public static async Task RunBot(){
while (true){
var u = await bot.MakeRequestAsync(new GetUpdates() { Offset
= offset });
foreach (var update in u)
{
offset = update.UpdateId + 1;
var text = update.Message.Text;
// here I want to get the data like this, but it doesn't work
if (update.ChosenInlineResult != null){
Console.WriteLine("Chosen Inline Result: " +
update.ChosenInlineResult.ToString());
}
switch(text){
case "Something":{
var req = new SendMessage(update.Message.Chat.Id, "راهنما") { ReplyMarkup = inlineKeyboardMarkup };
await bot.MakeRequestAsync(req);
break;
}
}
}
}
}
you must replace this
if (update.ChosenInlineResult != null){
Console.WriteLine("Chosen Inline Result: " +
update.ChosenInlineResult.ToString());
}
with something like This :
if (update.CallbackQuery != null)
{
Console.WriteLine(val.CallbackQuery.Message+"-"+val.CallbackQuery.Data);
}
I've finished a program in C# which integrates with Facebook and posts to more than one group in a click
but I am facing a problem right now when there is a group that you don't have a permission to post to I can't complete posting to the rest
here's the post function
I put it in other Class
public static bool PostImage(Frm form,string AccessToken, string Status, string ImagePath)
{
try
{
if (form.listBox2 .SelectedItems .Count > 0)
{
string item;
foreach (int i in form. listBox2.SelectedIndices)
{
item = form.listBox2.Items[i].ToString();
groupid = item;
FacebookClient fbpost = new FacebookClient(AccessToken);
var imgstream = File.OpenRead(ImagePath);
dynamic res = fbpost.Post("/" + groupid + "/photos", new
{
message = Status,
File = new FacebookMediaStream
{
ContentType = "image/jpg",
FileName = Path.GetFileName(ImagePath)
}.SetValue(imgstream)
});
result = true;
}
}
return result;
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
return false;
}
}
You need to put a try catch block inside the loop. Then, in the catch block you log the error (or do whatever you want with it) then continue the loop:
foreach (int i in form. listBox2.SelectedIndices)
{
try
{
item = form.listBox2.Items[i].ToString();
groupid = item;
FacebookClient fbpost = new FacebookClient(AccessToken);
var imgstream = File.OpenRead(ImagePath);
dynamic res = fbpost.Post("/" + groupid + "/photos", new
{
message = Status,
File = new FacebookMediaStream
{
ContentType = "image/jpg",
FileName = Path.GetFileName(ImagePath)
}.SetValue(imgstream)
});
result = true;
}
catch(exception excp)
{
//Do something with the exception
}
}
Now I don't know exactly how your code works, but this should give you a rough idea.
