Vbscript| Basic Tutorial | Operation VBScript has a complete set of operators, including arithmetic operators, comparison operators, join operators, and logical operators.
Operator Precedence
When an expression contains more than one operator, each part is evaluated in a predetermined order, which is called the operator precedence. You can use parentheses to cross this order of precedence, forcing some pa
Script, language vendors can establish a standard Script runtime language. Microsoft will provide support for running VBScript. Microsoft is defining ActiveX Script standards with multiple Internet groups to make the Script Engine interchangeable. ActiveX Script is available in Microsoft Internet Explorer and Microsoft Internet Information Server.

As a developer,
return value of all functions in VBScript.
The simplest Variant can contain numeric or string information. A Variant is used as a numeric processing in a numeric context and is used as a string in the context of a string. That is, if you use data that looks like a number, VBScript assumes it is a number and handles it in a digital way. Similarly, if the data us

The above 第一、三、四、六 several algorithms have a common feature: either one of the languages has a unique function, or in regular expression matching and distance computing, the difference between the two languages is very large enough to become a very meaningful mixed language programming test project. This gives us two additional scenarios for testing these algo
execute Scripts (eval () functions, execscript () methods, and so on) within your scripts. In short, you can write scripts in your script. This feature is useful when you work with DHTML, because you can dynamically manipulate the DHTML document model. VBScript does not have this feature. For example, in the JavaScript of the client you can use syntax like this:
Execscript ("On Error Resume Next:object.ex
MSDN, not to be repeated here.
8, string processing
The string processing of VBScript and JavaScript used to be the focus of netizens ' contention that the handling of strings was essentially
, the reason why I put forward this part alone, but also want to cause netizens to do some more detailed discussion.
In VBScript, strings are just a simple data type and provide a very rich string-handling function,
particular part of the data, use the Skip or SkipLine method. The result text of the Read method exists in a string that can be displayed in a control, or it can be parsed, connected, and so on by string functions such as left, right, and Mid.
The following VBScript example demonstrates how to open a file and how to write data to a file and read data from a file:
Sub Readfiles
Dim FSO, F1, TS, s
Const For
VBScript data type
VBScript has only one data type, variant, called Variant type. Varriant is a special type of data that, depending on how it is used, can contain different categories of information. Because the variant is the only data type in VBScript, it is also the data type of the return value of all function
Any practical project development must be multi-file. However, creating a multi-File Project in VBScript requires a little trouble,
Code The support for reuse is not very good. In the C/C ++ project, we are used to using functions in other modules by using an Include statement and declaring the original form of a function, such a complex project can be easily divided into small modules for easier understan

1) function example php: functioninc ($ val) {return $ val + 1;} is also a function, but no return value. Jscript, javascript: functioninc (val) {returnval + 1;} process definition is the same as above. VBScript: functioninc 1) function example
Php: function inc ($ val)
The {return $ val 1;} process is also a function, but there is no return value.
Jscript, javascript:
Function inc (val)
{Return val 1 ;}
The process is defined as above.
.
So I need to write VBScript code to solve the file upload problem. This is not an inevitable choice, because VBScript is a scripting language that can only use variants data types and does not provide many built-in functions to manage binary data and byte arrays.
To understand the upload process, you first need to know how the data is sent from the browser t
In VBScript, the script interpreter does not handle any errors it finds, and runs the next statement using the on error resume next statement. Once the statement has been processed, the script engine will continue to run the subsequent program, regardless of any errors that have been found. However, this process is only applicable to environments where statements are executed sequentially. In other words, it is not applicable to nested

of regular expressions is a language with unknown string processing capabilities. VBScript is a subset of Visual Basic and has rich string processing functions. Similar to C, JScript does not have this capability. Regular Expressions significantly improve the string processing capability of JScript. However, it may be more efficient to use regular expressions in VBScri
parameter from JavaScript. Then he would return the most appropriate value to JavaScript. Let's take a look at how function todollars (x) is referenced.
function Add (x,y)
{
result = x + y;
result = Todollars (result);
return result;
}
function Add (x,y) is a JavaScript function. From the middle of the function you can see
result = Todollars (result);
The line above is actually a call from VBScript to JavaScript.

Anyone who has done industrial control knows that the support for scripting language is a basic function (such as iFIX and Kingview) that standard configuration software should possess ). Can we implement similar functions using VB?We all know that Microsoft provides the Micrsoft script Control 1.0 control, we also saw the use of this control in VB (for example, using the executestatement method to execute the script command executestatement ("msgbox"
