Form1 triggers Form2 to open. Form2 has overloaded constructor which takes calling form as argument and provides its reference to Form2 members. This solves the communication problem. For example I’ve exposed Label Property as public in Form1 which is modified in Form2. With this approach you can do communication in different ways. Download Link for … Read more
Hmya, the enduring mystique of DoEvents(). There’s been an enormous amount of backlash against it, but nobody ever really explains why it is “bad”. The same kind of wisdom as “don’t mutate a struct”. Erm, why does the runtime and the language supports mutating a struct if that’s so bad? Same reason: you shoot yourself … Read more
Once you go past 100% (or 125% with the “XP-style DPI scaling” checkbox ticked), Windows by default takes over the scaling of your UI. It does so by having your app render its output to a bitmap and drawing that bitmap to the screen. The rescaling of that bitmap makes the text inevitably look fuzzy. … Read more
As per Prerak K’s update comment (since deleted): I guess I have not presented the question properly. Situation is this: I want to load data into a global variable based on the value of a control. I don’t want to change the value of a control from the child thread. I’m not going to do … Read more
Easiest is StreamReader and StreamWriter: using (var writer = new StreamWriter(@”C:\blah\somefile.txt”)) { writer.WriteLine(“Hello!”); } using (var reader = new StreamReader(@”C:\blah\somefile.txt”)) { var line = reader.ReadLine(); }
Don’t reinvent the wheel, use a 3rd party like FileHelpers; then you can use attributes to ignore the first row, for example.
You might want to look into a more complex type of dialog box. Perhaps one with a textbox? This will require launching another form. (see how to display textBox control in MessageBox?)
Fine, here you go. Passing the textbox values as arguments in the parameter. public sealed partial class MainPage : Page { public MainPage() { this.InitializeComponent(); txtName.Text = “Your name”; tbxAge.Text = “Your age”; tbxDinner.Text = “Your dinner”; OutputNewValues(txtName.Text, tbxAge.Text, tbxDinner.Text); } private void OutputNewValues(string name, string age, string dinner) { string answer = “Hello, ” … Read more
You didn’t give any info about the problem you have so I assume the thing you forgot is adding the required ‘s around the from.Text and to.Text in your select command. Also, you should use Date validation to validate if the given text is a date. DateTime dtfrom; DateTime dtto; if(DateTime.TryParse(from.Text,out dtfrom) && DateTime.Parse(to.Text,out dtto);) … Read more
It depends on the drawing environment you’re using. For example, if you use HTML5 canvas, you could rotate the canvas, draw the rectangle and then return the canvas to the original position, obtaining the “rotated” rectangle. You should check your environment documentation for further info or give more info in the question so we can … Read more
