I am really new to coding, never studied it or something similar, just learning it myself, never done it before, but I am trying to create my first real application right new.
However, I have some problems for 2 days which I just can't figure out, so I hope you can help me out.
Alright, so before the youtubedlCurrentWorker_Process() is created, I did define 'public string CurrentYouTubeDLVersion'.
How ever, when a button in my application executes the youtubedlCompareVersion_Process(), the CurrentYouTubeDLVersion string is empty, when it comes at the compare point.
Below is just a little part of my code.
Why is the string CurrentYouTubeDLVersion empty in the CompareVersion while the GetCurrentVersion ran before it?
Even if I double click "CurrentYouTubeDLVersion" in Visual Studio, it won't show a link to the one in the GetCurrentVersion_Process.
namespace MediaDownloader
{
public partial class updates : UserControl
{
public string LatestYoutubeDLVersion;
public string CurrentYouTubeDLVersion;
public void youtubedlGetCurrentVersion_Process()
{
if (File.Exists(YouTubeDLPath))
{
//Here I get the current version of youtube-dl.exe, to get the version number, we have to run youtube-dl.exe --version
Process youtubedl = new Process();
youtubedl.StartInfo.CreateNoWindow = true;
youtubedl.StartInfo.UseShellExecute = false;
youtubedl.StartInfo.RedirectStandardOutput = true;
youtubedl.StartInfo.RedirectStandardError = true;
youtubedl.StartInfo.FileName = YouTubeDLPath;
youtubedl.StartInfo.Arguments = " --version";
youtubedl.Start();
string CurrentYouTubeDLVersion = youtubedl.StandardOutput.ReadToEnd();
this.Dispatcher.Invoke((Action)(() =>
{
CurrentYouTubeDLVersionText.Text = "Current youtube-dl.exe version: " + CurrentYouTubeDLVersion;
YouTubeDLVersionStatusText.Text = null;
UpdateYouTubeDL.IsEnabled = false;
}));
}
public void youtubedlCompareVersion_Process()
{
youtubedlGetCurrentVersion_Process();
string LatestYoutubeDLVersion = WebClient.DownloadString("https://yt-dl.org/latest/version");
MessageBox.Show("Latest:" + LatestYoutubeDLVersion + "Current " + CurrentYouTubeDLVersion);
int YouTubeDLUptodate = CurrentYouTubeDLVersion.CompareTo(LatestYoutubeDLVersion);
if (YouTubeDLUptodate < 1)
{
YouTubeDLVersionStatusText.Text = "Your youtube-dl.exe is out of date, please click the button below to update.";
UpdateYouTubeDL.IsEnabled = true;
}
else
{
YouTubeDLVersionStatusText.Text = "youtube-dl.exe is up to date!";
UpdateYouTubeDL.IsEnabled = false;
}
}
}
Inside the youtubedlGetCurrentVersion_Process method, you're creating a new CurrentYouTubeDLVersion string, and it's completely separate from the public CurrentYouTubeDLVersion you added to the top of the class.
string CurrentYouTubeDLVersion = youtubedl.StandardOutput.ReadToEnd();
Assign to the class-level variable you made, instead of creating a new string:
CurrentYouTubeDLVersion = youtubedl.StandardOutput.ReadToEnd();
Then the value will be available to you in youtubedlCompareVersion_Process.
Take out the 'string' in front of CurrentYouTubeDLVersion and it should work
public youtubedlGetCurrentVersion_Process()
{
/* removed code to make easier to read */
//string CurrentYouTubeDLVersion = youtubedl.StandardOutput.ReadToEnd();
CurrentYouTubeDLVersion = youtubedl.StandardOutput.ReadToEnd();
/* removed code to make easier to read */
}

Created a simple class with one element, a string [] array and filled it with elements. I want to be able to add and delete elements in this array anywhere in my application, but it is not accessable. been trying variations for two days so coming to the best for help.
enter code here
public static void TestSlots()
{
String currentBehavior = _core.GetVariable("$_current_name", false);
bool success1 = _core.ApiApp().SetDiagOutput("MYWARNING " + currentBehavior + " is");
int indexNumber = MedIntents.medIntents.IndexOf(currentBehavior);
;
if (indexNumber < 0)
{
return;
}
else
{
//Global.MedIntents.RemoveAt(indexNumber);
bool success = _core.ApiApp().SetDiagOutput("MYWARNING " + currentBehavior + " removed");
}
//now check if they asked or hit more than one important entity
return;
}
// Console.WriteLine("Hello World!");
}
internal class MedIntents
{
public string[] medIntents = new string[] {
"any_chills",
"constant_or_intermittent",
"gradual_or_sudden",
"had_them_before",
"how_often",
"howdoesitstart",
"hurt_elsewhere",
"nausea_or_vomitting",
"numbness",
"pain_relief",
"relation_to_food_or_medical",
"scaleofone2ten",
"warning_signs"
};
medIntents is an instance member. You may want to convert it to a static member. To prevent modification, you can add the readonly modifier. – Crafted Pod 2 hours ago
I have run into an issue.
I am creating a small application for working with our phone configuration files.
I have created a Class called Phone and given it 4 properties:
private int extension;
private String sExtension;
private String userName;
private String filePath;
I have included the respective get/set methods as well as:
public String Extension
{
get
{
return sExtension;
}
}
public String Path
{
get
{
return filePath;
}
}
I have created a utility class that does most of the static work. Including a method to create a List<Phone> of phone objects to populate the ListBox.
Everything works to the point of returning the List<Phone> back as the datasource for the ListBox. I have set both the:
fileList = Directory.EnumerateFiles(path, "ext-*");
lst_Files.DataSource = Utility.populatePhoneList(fileList);
lst_Files.DisplayMember = "Extension";
lst_Files.ValueMember = "Path";
The problem I am still experiencing is the ListBox is still being populated by the object name (in reference to MSDN Article)
I have read through a couple articles on this forum and most mention the same issue that I may not be calling ListBox.DisplayMember correctly but I believe I am.
Edit: I have tried returning a List<T>, ArrayList,Array[].
Edit: Code for utility
public static List<Phone> populatePhoneList(IEnumerable<String> newFileList)
{
List<Phone> phones = new List<Phone>();
Phone p = null;
for (int i = 0; i < newFileList.Count(); i++)
{
p = getPhoneInfo(newFileList.ElementAt(i));
phones.Add(p);
}
return phones;
}
public static Phone getPhoneInfo(String newPath)
{
StreamReader sr = new StreamReader(newPath);
Phone p1 = new Phone();
p1.setFilePath(newPath);
String testLine;
while (sr.Peek() >= 0)
{
testLine = sr.ReadLine();
if (testLine.Contains("reg.1.displayName"))
p1.setUserName(testLine.Substring(testLine.IndexOf("\"") + 1, ((testLine.LastIndexOf("\"") - 1) - testLine.IndexOf("\""))));
if (testLine.Contains("reg.1.address"))
p1.setExtension(testLine.Substring(testLine.IndexOf("\"") + 1, ((testLine.LastIndexOf("\"") - 1) - testLine.IndexOf("\""))));
}
return p1;
}
After digging into this problem over the weekend I started disabling some event handlers on the ListBox and found that it is working as it should be. I found that my ListBox.SelectedIndexChanged event was catching the list before the system completely populated. My solution was to turn ListBox.SelectionMode to none then reset it once the ListBox was filled.
We're creating a WPF app in which we execute python scripts from different Test Stations and show the output in its corresponding output panel, To run the scripts in parallel we are using Task but when we run the scripts in parallel from the stations, We are getting the output of other stations also into the station that is started first, we're using the following code,
private void ZmqStatusListener(string endPoint)
{
using (Context context = new Context())
{
StatusPort = string.Empty;
TestResultPort = string.Empty;
using (Socket server = context.Socket(SocketType.REP))
{
try
{
if (isStatusContextActive == false || isPortChanged == true)
{
server.Bind(endPoint);
isStatusContextActive = true;
}
}
catch (ZMQ.Exception ex)
{
if (ex.Errno != 100)
{
string IPCPort = _globalParameters.GlbParam.GlbParamIpcStartPort;
if (IPCPort == string.Empty)
{
IPCPort = "0";
}
if (endPoint == EditorConstants.PortAddress.PortPrefix + IPCPort)
{
StatusPort = endPoint;
TestReultError = EditorConstants.CommonMessageTypes.TestReultError + ex.Message + EditorConstants.CommonMessageTypes.StackTraceMessage + ex.StackTrace;
}
StopExecOfScript(default(object));
isCancelledtask = true;
ScriptStatusDesc = new ScriptStatusDesc()
{
Status = "Failed",
statusDescription = "Failed"
};
}
}
while (true)
{
string message = server.Recv(Encoding.UTF8);
UpdateTestResults(message);
server.Send(" ACK", Encoding.UTF8);
// if (message == "Test Passed")
//break;
}
}
}
}
and for testing purpose we're breaking the while loop in this code based on a test message we kept in the python script, then we are able to get the output in the respective station correctly but this way we can only run in a synchronous fashion which we don't want as we require to run the test stations in parallel and the while loop should not break as it should be listening for the response.
We were able to solve the issue by getting clues doing a sample app to reproduce the issue and to first know whether our ClrZmq pattern was correct for us or not and it is correct. The resolution we followed is that when we needed to bind that data to its corresponding View's Model object in its ViewModel so had to retrieve View's DataContext which is of Type ISomeXViewModel for the particular TestStation using an Id of that TestStation we did this cos all of our TestStations are dynamically added and we even store it to be accessed wherever necessary. This issue was caused to due multiple instances of UserControls so we explicitly needed to update the TestStation manually with a little more effort.
Sample Code Snippet
private void BindTestResult(string xmlPayLoad)
{
// converting xmlPalLoad to a class/model object
ITestStationViewModel viewModel = (ITestStationViewModel)((IView)DynamicTestStationsGrid.Children[StationNumber].Content).DataContext;
// IView class has DataContext property so I am type casting the Content which is ContentControl to IView type first and later to ITestStationViewModel
viewModel.TestStationModel = xmlPayLoadModel;
}
Thanks.
Backstory,
So I am working on a personal assistant program and all my voice commands are translated into strings for parsing.
I have set up the ability to search Google and display the results in a text block as hyperlinks.
Now I want to be able to set up the ability to open these links with speech(string commands). So far I have the following.
This bit allows me to search using the Google Custom Search API with a custom "GoogleSearch" class.
public void search_google(string query) //Google Searching
{
#region link strings
string result_1 = "";
string result_2 = "";
string result_3 = "";
string result_4 = "";
string result_5 = "";
string result_6 = "";
string result_7 = "";
string result_8 = "";
string result_9 = "";
string result_10 = "";
#endregion
GoogleSearch search = new GoogleSearch()
{
Key = "{apikey}",
CX = "{cxkey}"
};
search.SearchCompleted += (a, b) =>
{
tab_control.SelectedIndex = 2;
int p = 1;
search_results.Text = String.Empty;
foreach (Item i in b.Response.Items)
{
Hyperlink hyperLink = new Hyperlink()
{
NavigateUri = new Uri(i.Link)
};
hyperLink.Inlines.Add(i.Title);
hyperLink.RequestNavigate += Hyperlink_RequestNavigate;
hyperLink.Name = "result_" + p;
//search_results.Inlines.Add(hyperLink.Name);
search_results.Inlines.Add(Environment.NewLine);
search_results.Inlines.Add(hyperLink);
search_results.Inlines.Add(Environment.NewLine);
search_results.Inlines.Add(i.Snippet);
search_results.Inlines.Add(Environment.NewLine);
search_results.Inlines.Add(Environment.NewLine);
p++;
};
};
search.Search(query);
}
It outputs my results in a series of hyperlinks and text snippets into a text block that I set up on the main window. The search process is triggered by my input parser which looks for the keywords "search" or "Google".
The next step would be the input parser checking for keyword "result" to look for the hyperlink to open. Here is the unfinished code for that.
if ((Input.Contains("result") || Input.Contains("Result")) && tab_control.TabIndex == 2)
{
int result_number = 0;
switch(result_number)
{
case 1:
if (Input.Contains("first") || Input.Contains("1st"))
{
// open hyperlink with name property result_1
}
break;
case 2:
// additional cases added up to 10 with similar syntax for parsing.
}
}
You can open a hyperlink in the default browser using:
Process.Start(myHyperlink);
EDIT
Based on your comments, it seems you are having trouble accessing result_1 (etc.).
You define result_1 as a variable local to the method search_google()
public void search_google(string query) //Google Searching
{
#region link strings
string result_1 = "";
That means result_1 is only visible within that method.
Your if and switch statements do not appear to be part of search_google(), so they can never see result_1. If those statements are in a different method, you can work around that issue by moving result_1 to the class level (outside of search_google()).
ON a site note, rather than defining ten individual result strings, you probably want to use an array of strings or a list of strings.
I have a CSV file in this format:
"Call Type","Charge Type","Map to"
"51","","Mobile SMS"
"52","","Mobile SMS"
"DD","Local Calls","Local Calls"
"DD","National Calls","National Calls"
First two columns are the "source information" that my C# will insert, and the last column is what it will return.
Currently what I am doing is a switch statement hardcoded in c#.
var File001 = from line in File.ReadLines(bill_file)
let l = line.Split(',')
select new
{ CallType = ICD_map(l[5],l[3])}
where
l[5] = "51";
l[3] = "";
private static string ICD_map(string call_type_description, string call_category,)
{
case "51":
case "52":
return "Mobile SMS";
default:
return "Unknown";
}
I want this to be an expandable list thus my new method is to load the mapping table from a csv file. Can you suggest any improvements to this method to make my definition library expandable (hoping CSV file okay for this purpose, it is only 100 lines long so far, so not concerned about memory management).
What I have tried so far is:
class ICD_Map2
{
private string call_type;
private string charge_type;
private string map_to;
// Default constructor
public ICD_Map2() {
call_type = "Unknown";
charge_type = "Unknown";
map_to = "Unknown";
}
// Constructor
public ICD_Map2(string call_type, string charge_type, string map_to)
{
this.call_type = call_type;
this.charge_type = charge_type;
this.map_to = map_to;
}
}
List<ICD_Map2>maps = new List<ICD_Map2>();
private void button2_Click(object sender, EventArgs e)
{
// Start new thread to create BillSummary.csv
button1.Enabled = false;
maps.Clear();
//load mapping file
var reader = new StreamReader(File.OpenRead(#"Itemised_Call_Details_Map.csv"));
while (!reader.EndOfStream)
{
var line = reader.ReadLine();
var values = line.Split(',');
maps.Add(new ICD_Map2(values[0].Replace("\"",""), values[1].Replace("\"",""), values[2].Replace("\"","")));
textBox2.AppendText(Environment.NewLine + " Mapping: " + values[0].Replace("\"", "") + " to " + values[1].Replace("\"", ""));
}
I have loaded the CSV file to my program but I am unable to do the lookup from LINQ. Can you tell me the next process.
Open to any other method.
Thanks for your time.
I would suggest you to go with
http://www.codeproject.com/Articles/9258/A-Fast-CSV-Reader
It will give you lots of flexibility to play around with your code.
We have been using it in our projects, and it's really helpful to have full control inplace of writing generic CSV code which is prone to errors and bugs
