C# how to make the stored file to cap at 100 items? -

-

I am trying to create a small program that takes input from the user and stores it on file, but I cap that file on 100 elements:

Suppose that the user adds 100 names and the next name the user adds will show that "the list is complete"

here I The code that is so far: 

  public form 1 () {InitializeComponent (); } Private string SongName, ArtistName; Public Zero Registry () {List & lt; Name & gt; Music list = new list & lt; Name & gt; (); // Create a list of MusicList.Add (new name (SongName = txtSongName.Text, ArtistName = txtArtistName.Text)); // Add new element in NameClass // Check if input is correct (txtSongName.TextLength & lt; 1 || txtArtistName.TextLength & lt; 1) {Info Info = new info (); Info.Show (); } Else // If the input will be stored in the correct data {// Create a file to store a data. StreamWriter FileSaving = New StreamWriter ("MusicList" is true); {String sName = MusicList [i] .songName for (Int i = 0; I & lt; MusicList.Count; i ++) // To create a new variable to maintain the name string, aName = MusicList [i] .artistName; // Create a new variable to save the file. Write (name + "by"); // Save the file to add SongName FileSaving.WriteLine (aName); // Add ArtistName to save file} FileSaving.Close (); }} Private Zero btnEnter_Click (Object Sender, EventArgs e) {Registry (); // Set the text box to empty so that the user txtArtistName.Text = ""; TxtSongName.Text = ""; } Private Zero btnClose_Click (Object Sender, EventArgs e) {Application.Exit (); }    
 
 
  as the area of ​​the class private const int MAX_STORED_SONGS = 100; // (Int i = 0; i & lt; MusicList.Count & i & lt; MAX_STORED_SONGS; i ++) // ... for later loop (MusicList.Count> MAX_STORED_SONGS) error message label .txt = "The list is complete, only 100 items added"   
 I'm not sure what your list picker looks like, but you probably have more than 100 using them using some javascript / verification The client side wants to stop selecting the item before submitting the page.  
 What's not clear about your code, it seems that the user submits a single song, then you create a new empty vocabulary, add a single item, but you loop through it As if there are more than one item, you should start by reading the file to decide how many songs in it, so that you can determine when 100 songs are there.

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
