Recently in a WEB project, you need to call OCX to connect the card reader. Originally do not want to use OCX technology, because the ActiveX technology is produced by Microsoft, so that the entire system can only use IE browser (other browsers can be in the form of plug-ins to support OCX calls). But trying a lot of ways to invoke client DLL discovery is not going to make sense. Finally helpless under, only then intends to study the OCX technology. Online all say that the ActiveX technology is

First, prefaceAfter several studies, now we have mastered the entire development process of ActiveX, but to play the true power of ActiveX, must rely on JS. Let's learn now!Second, JS call ActiveX methodSimply write a public method in the UserControl subclass (that is, the custom ActiveX control).C#[Guid ("0203dabd-51b8-4e8e-a1eb-156950ee1668")] Public Partial class　　Uploader:usercontrol, iobjectsafety{

JS in a set of convenient way to get the element size is the offset family;2 The offset structure is described as:3 Offset Common Properties1 offsetwidth offsetheight Get the width and height of the object (own, unrelated to others)Offsetwidth = Width+padding+border2 offsetleft OffsetTop Returns the position to the left of the upper box (with positioning) i

"explorer", URL, null, sw_show); return L ""; };Then we compile the project, and a file named ACExtensionDemo.dll is generated, and the file is copied to the extensions in the installation directory.So we can invoke the extension method we just wrote in the script, and here we use the method called extern "C" __declspec (dllexport) wchar* Sum (WCHAR *params) as an example to illustrate this.The script should write like thisThe object that constructs the extension method, where the function is

will delete all attributes whose subscript is greater than or equal to the new length. Another point is how the length value of the array comes from. It is correct to add one of the largest numeric index values, but if the empty slot is also counted, the length value is the number of elements in the array. The above figure explains: From the values, we can see that an array a, a [0], and a [10] have been assigned values. At this time, the length of a is 11, there are nine empty slots in the mi
