Re: Task Parrallel Richard Deeming18-Dec-14 1:34 Richard Deeming 18-Dec-14 1:34  For .NET 4.5 with async / await, using await Task.WhenAll(tasks); is better than using Task.WaitAll(tasks);. The former releases the current thread until the tasks are complete; the latter blocks the current thread waiting for the tasks to complete.

Now I start to rewrote the code, but i discover a surprise, to add, delete, modify, list the appointments in 10 different google calendar, i need to do the authentication with OAuth2.0. And now appear the problem, I have stressed google to find an example of code, but every code was write for webapplication(asp.net) and not for a standalone windows application. Somebody can help me to find a solution/example to integrate in my code???? How can I add rows in datagridview in VS? turbosupramk317-Dec-14 4:28 turbosupramk3 17-Dec-14 4:28  Hi, I need to add rows in datagridview in Visual Studio in design mode (not programmatically), how can I add rows this way? I was able to add columns but not rows? Re: How can I add rows in datagridview in VS? PIEBALDconsult17-Dec-14 4:34 PIEBALDconsult 17-Dec-14 4:34  You don't. Adding data to the DataSource, usually a DataTable, is a run-time thing. Re: How can I add rows in datagridview in VS? turbosupramk317-Dec-14 4:40 turbosupramk3 17-Dec-14 4:40  Thanks for clearing that up. Do you know why they would allow you to add columns via design mode? Re: How can I add rows in datagridview in VS? OriginalGriff17-Dec-14 5:20 OriginalGriff 17-Dec-14 5:20  Yes - so that you can fix the "design" of the table and add rows directly at run time instead of using a DataTable.

Re: How can I add rows in datagridview in VS? turbosupramk317-Dec-14 5:29 turbosupramk3 17-Dec-14 5:29  Thank you. I cannot get anything to work to add the code at runtime, besides having a button click add row by row (which I do not want and cannot use) so somehow I've done something in the beginning to break it in trying to figure this out, and now that I've asked for help and gotten working examples, it is thwarting my ability to get it to work properly. Even the code from the msdn site isn't working and my data grid is indeed called dataGridView1? [code] private void Form1_Load(object sender, EventArgs e) { InitializeDataGridView(); } private void InitializeDataGridView() { // Create an unbound DataGridView by declaring a column count. dataGridView1.ColumnCount = 4; dataGridView1.ColumnHeadersVisible = true; // Set the column header style. DataGridViewCellStyle columnHeaderStyle = new DataGridViewCellStyle(); columnHeaderStyle.BackColor = Color.Beige; columnHeaderStyle.Font = new Font("Verdana", 10, FontStyle.Bold); dataGridView1.ColumnHeadersDefaultCellStyle = columnHeaderStyle; // Set the column header names. dataGridView1.Columns[0].Name = "Recipe"; dataGridView1.Columns[1].Name = "Category"; dataGridView1.Columns[2].Name = "Main Ingredients"; dataGridView1.Columns[3].Name = "Rating"; // Populate the rows. string[] row1 = new string[] { "Meatloaf", "Main Dish", "ground beef", "**" }; string[] row2 = new string[] { "Key Lime Pie", "Dessert", "lime juice, evaporated milk", "****" }; string[] row3 = new string[] { "Orange-Salsa Pork Chops", "Main Dish", "pork chops, salsa, orange juice", "****" }; string[] row4 = new string[] { "Black Bean and Rice Salad", "Salad", "black beans, brown rice", "****" }; string[] row5 = new string[] { "Chocolate Cheesecake", "Dessert", "cream cheese", "***" }; string[] row6 = new string[] { "Black Bean Dip", "Appetizer", "black beans, sour cream", "***" }; object[] rows = new object[] { row1, row2, row3, row4, row5, row6 }; foreach (string[] rowArray in rows) { dataGridView1.Rows.Add(rowArray); } } [/code] Re: How can I add rows in datagridview in VS? turbosupramk317-Dec-14 5:48 turbosupramk3 17-Dec-14 5:48  Sigh ... got it. For some reason (this has happened a few times before) when I copy from the net private void Form1_Load(object sender, EventArgs e) { // something } Instead of allowing that function to be generated by visual studio, it does not recognize it and it ignores it?

Re: how to divide an image and find the center of each part by c# BillWoodruff2-Jan-15 5:19 BillWoodruff 2-Jan-15 5:19  I just noticed your question today. What you want to achieve is not clear. What do you mean by "difference:" you need to fully explain that. Does "absent" mean that there is only black in one of the six divisions of the Picture ? Or does it mean something else ? Detecting and comparing images is one thing (complex); detecting the presence of absence of a color in one rectangular area of a bitmap is another thing (simpler). «A man will be imprisoned in a room with a door that's unlocked and opens inwards ... as long as it does not occur to him to pull rather than push»  Wittgenstein validation for 10 digit phone number Jinxez16-Dec-14 19:11 Jinxez 16-Dec-14 19:11  ^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$ Re: validation for 10 digit phone number V.16-Dec-14 19:24 V. 16-Dec-14 19:24  Please read this[^] before posting...
