In a nutshell Build a list of available drives. Try to resolve the driveletter to an UNC name. Try to ping the drive. Edit regarding Bill’s comment if Google is not the referer, EE doesn’t show the answer for free. Links to EE are not helpful. OP found the article I’ve mentioned in my original … Read more
You should set DefaultCellStyle.WrapMode property of column to DataGridViewTriState.True. After that text in cells will be displayed correctly. Example (DataGridView with one column): dataGridView1.Columns[0].DefaultCellStyle.WrapMode = DataGridViewTriState.True; dataGridView1.Rows.Add(“test” + Environment.NewLine + “test”); (Environment.NewLine = \r\n in Windows)
The reason why you shouldn’t always use nullable types is that sometimes you’re able to guarantee that a value will be initialized. And you should try to design your code so that this is the case as often as possible. If there is no way a value can possibly be uninitialized, then there is no … Read more
Checking if events were fired can be done by subscribing to that event and setting a boolean value: var wasCalled = false; foo.NyEvent += (o,e) => wasCalled = true; … Assert.IsTrue(wasCalled); Due to request – without lambdas: var wasCalled = false; foo.NyEvent += delegate(o,e){ wasCalled = true;} … Assert.IsTrue(wasCalled);
There is one subtle difference between these two, which can be seen in the IL code – putting an explicit static constructor tells the C# compiler not to mark the type as beforefieldinit. The beforefieldinit affects when the type initializer is run and knowing about this is useful when writing lazy singletons in C#, for … Read more
Try to set the position to 0 of your stream and do not use your object but the object type. BinaryFormatter b = new BinaryFormatter(); s.Position = 0; return (YourObjectType)b.Deserialize(s);
Very few posts suggest using LOGON_TYPE_NEW_CREDENTIALS instead of LOGON_TYPE_NETWORK or LOGON_TYPE_INTERACTIVE. I had an impersonation issue with one machine connected to a domain and one not, and this fixed it. The last code snippet in this post suggests that impersonating across a forest does work, but it doesn’t specifically say anything about trust being set … Read more
You can use Linq to DataTable: var ids = dt.AsEnumerable().Select(r => r.Field<int>(“id”)).ToList(); UPDATE: Without Linq List<int> ids = new List<int>(dt.Rows.Count); foreach(DataRow row in dt.Rows) ids.Add((int)row[“id”]); Note for efficiency it’s better to use row[index] instead of row[columnName]. First one just gets column by index from columns array. Latter gets column index from internal dictionary which maps … Read more
Absolutely: class B { private A m_a = new A(); public event EventType EventB { add { m_a.EventA += value; } remove { m_a.EventA -= value; } } } In other words, the EventB subscription/unsubscription code just passes the subscription/unsubscription requests on to EventA. Note that this doesn’t allow you to raise the event just … Read more
TLS (Transport Level Security) is the slightly broader term that has replaced SSL (Secure Sockets Layer) in securing HTTP communications. So what you are being asked to do is enable SSL.
