The method.Invoke() call executes the delegate on the current executing thread. Using the BeginInvoke(method) ensures that the delegate is called on the GUI thread. This is the correct way of avoiding code duplication when the same method can be called both from the GUI thread and other threads.
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
In your deserialization code you’re creating a MemoryStream and XmlTextWriter but you’re not giving it the string to deserialize. using (MemoryStream memStream = new MemoryStream()) { using (XmlTextWriter textWriter = new XmlTextWriter(memStream, Encoding.Unicode)) { // Omitted } } You can pass the bytes to the memory stream and do away with the XmlTextWriter altogether. using … Read more
I had to get around something like your problem a while back. foreach (Object _obj in _explorer.CurrentFolder.Items) { if (_obj is MailItem) { MyMailHandler((MailItem)_obj); } } Hope that helps. The issue here is that _explorer.CurrentFolder.Items can contain more objects than just MailItem (PostItem being one of them).
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.
You can’t. The best you can do is render to a hardware accelerated device on an overlay, similar to what video players used to do. Basically, you paint your entire window blue, and render your graphics onto the video card, and internally the video card will replace the blue with the graphics. The downside to … Read more
You need to make a call to ConfigurationManager.RefreshSection in order to have the values re-read from disk.
It’s possible to redirect the standard input/output of console/dos applications using the Process class. It might look something like this: var processStartInfo = new ProcessStartInfo(“someoldapp.exe”, “-p someparameters”); processStartInfo.UseShellExecute = false; processStartInfo.ErrorDialog = false; processStartInfo.RedirectStandardError = true; processStartInfo.RedirectStandardInput = true; processStartInfo.RedirectStandardOutput = true; processStartInfo.CreateNoWindow = true; Process process = new Process(); process.StartInfo = processStartInfo; bool processStarted … 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)
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);
