When you do a dynamic fetch control, you often need to get the control based on the ID and manipulate the control at this time, using the

The file returned by the entire dump can be viewed as a multi-fork tree consisting of controls, each representing a control, and the number of spaces before the start of each row (a control) represents the control's hierarchy in this tree, as no spaces represent the root node, which is the decorview of the top of the window we often call.The algorithm of the above method understands the meaning of the sever
ActiveX controls and can use the tools provided by Delphi to quickly develop their own ActiveX controls. This article describes in detail the techniques provided by Delphi to quickly develop ActiveX controls.Ii. related knowledge of ActiveX controlsTo develop ActiveX controls, let's take a quick look at some of the relevant knowledge of ActiveX controls. In Delphi, an ActiveX control consists of the following parts: VCL (visual Component library) con
In the previous article we created a simple control firstcontrol, now let me explain how to use and debug your own controls. I want to write the process as detailed as possible, so that you want to learn the control development of friends easy to use, experts forgive.

NumericUpDown can also be called a micro-regulator (effect graph:), which can be used to perform a set of input controls about the values in the sequence. As early as in the Delphi era, it was popular to use the control. But on the web, to today only really appear the secondary control, it can be seen that the web implementation of the difficult, thanks to Ajax.
NumericUpDown is als

The three data binding controls ListBox, GridView, and Repeater are "efficient pagination". The ListBox and GridView have built-in pagination, but their efficiency is too low, and a small amount of data is acceptable, A large amount of data cannot be used at all. The Repeater control does not provide pag

Article We have discussed the basic theory about creating composite controls, and mastered the rendering method of composite controls through a typical application. This article will continue to explain how to create a composite control, focusing on how to implement events for the composite control.

The slider control (Slider control) is also called the track strip, which uses a small window with tracks and sliders and a scale on the window to allow the user to select a discrete data or a continuous range of values. Selection of data through the mouse or keyboard, which can be seen in many applications in win98/95, such as the mouse in the Control Panel, the
Alignment is one of the most frequently used layout methods, and you may have mastered this approach.
Suppose you have 4 controls

Suppose you have 4 controls
The effect of aligning on top
The effect of bottom alignment
If the selected controls may overlap after alignment, Microsoft Access does not overlap them, and the edges of those controls are arranged adjacent to each other.
Suppose you have 4 controls

First, a new Class1 object is created in Form1 's form loading and a reference to itself is passed into its constructor, and a thread in the constructor of Class1. The method event that the thread is acting on is an Add method in this class. The content of the Add method is to put a textbox on the Form1.However, there are several issues that you should be aware of in this process:1. Which is the main thread? The so-called main thread is the first one that starts, starting with main. This form of
The example in this article describes the implementation method for the button control of the ASP.net custom Web server control. Share to everyone for your reference. The implementation methods are as follows:

Using the ASP. NET menu control, you can develop static and dynamic display menus for ASP. NET web pages.
The Menu Control has two display modes: static mode and dynamic mode. Static display means that the menu control is always fully expanded. The entire structure is visible. You can click any part. In the dynamically displayed menu, only the specified part is

With the development and maturity of. NET technology, server controls have become increasingly popular among developers. At the same time, the development of server controls also showed some trends, for example, the more powerful the function, a lot of functions are gradually transferred from the server side to the client. In addition, server controls are becoming more and more beautiful. This may be due to the increasing emphasis on functions and appearance of Windows operating systems. This ar
