  1. POProgressBar that updates as dictionary loads
    text
    copied!<p>Well I think I know the answer to this, but I would appreciate anybody confirming what I suspect.</p> <p>I have a large <code>dictionary</code> of zip codes that needs to load on program launch. It takes between 10-15 seconds, and I'd like to have a <code>progressbar</code> that could show, well, the progress. I can make the progress bar, and I have the total count specified as a setting. But from what I've been finding on other questions, it seems that <code>dictionary.count</code> cannot be bound to the progressbar with any hope of it updating regularly.</p> <p>Is this true? And if so, is there another way around it?</p> <p>Right now the dictionary is hardcoded, but I plan on changing that at some point in the future and have it load from a file instead. I know at that point I can just use a <code>foreach</code>loop to update the count each time around, but this seems kind of kludge-ish. Is there a better way to implement?</p> <p><strong>Edit:</strong></p> <p>As requested, code that loads the dictionary of zipCodes(there are actually about 40,000 more entries, but I thought I'd save space :p):</p> <pre><code>static class ZipCodes { #region Methods public static string GetValue(string key) { string result; if (zipCodeDictionary.TryGetValue(key, out result)) { return result; } else { return null; } } public static int GetCount() { return zipCodeDictionary.Count(); } #endregion #region ZipCode Dictionary Definition static Dictionary&lt;string, string&gt; zipCodeDictionary = new Dictionary&lt;string, string&gt;(); public static void PopulateZipCodeDictionary() { zipCodeDictionary.Add( "00501", "Holtsville, NY" ); zipCodeDictionary.Add( "00544", "Holtsville, NY" ); zipCodeDictionary.Add( "00601", "Adjuntas, PR" ); zipCodeDictionary.Add( "00602", "Aguada, PR" ); zipCodeDictionary.Add( "00603", "Aguadilla, PR" ); zipCodeDictionary.Add( "00604", "Aguadilla, PR" ); </code></pre>
