You should call GetFileSizeEx which is easier to use than the older GetFileSize. You will need to open the file by calling CreateFile but that’s a cheap operation. Your assumption that opening a file is expensive, even a 12GB file, is false. You could use the following function to get the job done: __int64 FileSize(const … Read more
As stated, your loop will not hog the CPU. But beware: Windows is not a real-time OS, so you will not get 1000 wakes per second from Thread.Sleep(1). If you haven’t used timeBeginPeriod to set your minimum resolution you’ll wake about every 15 ms. Even after you’ve set the minimum resolution to 1 ms, you’ll … Read more
Yes, the first means “match all strings that start with a letter”, the second means “match all strings that contain a non-letter”. The caret (“^”) is used in two different ways, one to signal the start of the text, one to negate a character match inside square brackets.
A more extensive listing of problematic word characters if (buffer.IndexOf(‘\u2013’) > -1) buffer = buffer.Replace(‘\u2013’, ‘-‘); if (buffer.IndexOf(‘\u2014’) > -1) buffer = buffer.Replace(‘\u2014’, ‘-‘); if (buffer.IndexOf(‘\u2015’) > -1) buffer = buffer.Replace(‘\u2015’, ‘-‘); if (buffer.IndexOf(‘\u2017’) > -1) buffer = buffer.Replace(‘\u2017’, ‘_’); if (buffer.IndexOf(‘\u2018’) > -1) buffer = buffer.Replace(‘\u2018’, ‘\”); if (buffer.IndexOf(‘\u2019’) > -1) buffer = buffer.Replace(‘\u2019’, … Read more

With C++11, you can call the member function shrink_to_fit(). The draft standard section 23.2.6.2 says: shrink_to_fit is a non-binding request to reduce capacity() to size(). [Note: The request is non-binding to allow latitude for implementation-specific optimizations. —end note]
Taking advantage of short-circuiting in boolean expressions: int max(int a, int b, int c) { int m = a; (m < b) && (m = b); //these are not conditional statements. (m < c) && (m = c); //these are just boolean expressions. return m; } Explanation: In boolean AND operation such as x && … Read more
Without using of a control or form: using (System.Drawing.Graphics graphics = System.Drawing.Graphics.FromImage(new Bitmap(1, 1))) { SizeF size = graphics.MeasureString(“Hello there”, new Font(“Segoe UI”, 11, FontStyle.Regular, GraphicsUnit.Point)); } Or in VB.Net: Using graphics As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(New Bitmap(1, 1)) Dim size As SizeF = graphics.MeasureString(“Hello there”, New Font(“Segoe UI”, 11, FontStyle.Regular, GraphicsUnit.Point)) End Using
Yes, this is completely possible. Use the @functions keyword: @functions { public class MyClass { public MyClass() { Three = new List<string>(); } public string One { get; set; } public int Two { get; set; } public List<string> Three { get; set; } } }
