load them into an MDI application. To make them available, compile them as class libraries, and then add references to them in the configuration file. Dynamically loading other types of classes This technique can be used in addition to forms for other types of classes. However, the situation is relatively complex. In the previous example, the System.Windows.Forms.Form class interface was able to be bound early because we knew it was a form. Therefore, you can use the method of the form (for ex

approach to develop applications that no longer have significant boundaries between the three steps. In most languages, if an error occurs while writing code, the error is captured by the compiler when the application starts to compile. You must find and correct the error at this point, and then compile again, repeating the process for each found error. Visual Basic interprets the programmer as it enters

") { }} Basic concepts of C Language There are two types of floating points: Single-precision and double-precision,Its type specifiers are float Single-precision specifiers and double-precision specifiers. In Turbo C, the single-precision model occupies 4 bytes (32-bit) memory space. The value range is 3.4E-38 ~ 3.4E + 38. Only seven valid digits are allowed. The dual-precision model occupies 8 bytes (64-bit) memory space, and the value range is
