Recently, I have seen some basic InterOP problems on the Forum, giving me the motivation to write the previous. Net InterOP getting started series, and giving my friends who have just been involved in. Net InterOP a general concept. Every time I talk about. Net InterOP, the following figure is always displayed in my mind: The figure shows four typical scenarios of. Net InterOP. Previously, my colleagues and I discussed the applications of. NET and COM interoperability: Getting started with ca

You cannot call invoke or begininvoke on the control before creating a window handle. Close a form today and report this error. "You cannot call invoke or begininvoke on the control before creating a window handle. ", You don't have to think about it. It must have been the place that was not released.Now that you have encountered this problem, let alone the problem itself. Let's talk about other things.The

In general, when invoking UI controls in multithreading, it involves modifying the UI across threads, using delegates, such as the following: this. Invoke ((methodinvoker)delegate { true; });However, if I close the form prematurely when the multithreaded operation is not completed, InvalidOperationException will be thrown, prompting "invoke or

When the tostring () magic method treats an object as a string, it automatically calls this method and returns a certain string in this method, to indicate the result after the object is converted to a string. This magic method is commonly used. Note: If this method is not defined, the object cannot be used as a string! Example of the tostring () method not defined in the class: amp; lt ;? Phpini_set ( amp; #39; display_errors amp; #39;, amp; nbsp; 1); class... when the tostring () magic meth

creating a form handleWhen the window is created, the window does not create a handle, only Application.Run (form) or form. Show () is followed by a handle, that is, the window only displays or starts the message loop before the handle! If the form is created, the form is called in the main thread. Handler, if the handle has not yet been created, referencing the property will force the creation of the handle, which will have a deadly effect on the logic of Xi's ability.ishandlercreated PropertyD

CLR Interop is simply a technique for making unmanaged and managed code callable to each other. This technology enables developers to reuse existing managed or unmanaged builds and, depending on their needs, weighs the simplicity of managed code and the flexibility of unmanaged code, choosing a programming language that is appropriate for its own reality, without having to think too much about the language in which the reusable component is developed. Interop Chinese means interoperability, sinc

The following example uses a background thread to perform the calculation logic, which does not affect the foreground interface operation, which means You can perform other actions in the foreground UI interface. The focus is on the new thread, which calls a delegate method, which is required to populate the data to the foreground control because The foreground control is created in the original thread, so the Invoke method needs to be called in the n
