Loading DLL with Java in Windows

Java loads dynamically linked library files in classes.
Class file:
Static {
system.loadLibrary (” DLL file “);
}
The DLL file is under the package path of the project. For example: pro/bin/hell. DLL; (Pro project in the bin directory hello. DLL file)
Can’t find dependent libraries Can’t find dynamically linked libraries
 
Solution:
Winpcap can be installed to solve the problem. Download path: http://ftp-idc.pconline.com.cn/32017d10a844534eecd94d13ce732091/pub/download/201010/WinPcap_4_1_3.exe

Split keyword in ABAP when the separator is at the beginning and end of the string

We use the SPLIT keyword to SPLIT a string by a delimiter. If the delimiter is in the middle of the string (that is, if the first and last characters are not delimiters), we can easily see the result. But what if the delimiter is exactly the first or last of the string?
In the debug window, you can see all the row items in the inner table LT_SPLIT_TABLE after line 6 is executed, as shown in the following code.

DATA: lv_str         TYPE string,
      lt_split_table TYPE TABLE OF string.

lv_str = '/This/is/a/test./'.

SPLIT lv_str AT '/' INTO TABLE lt_split_table.


From the above test results, when the separator is at the beginning of the string, the left side of the separator will split an empty string; When a delimiter is at the end of a string, the empty string is not split to the right of the delimiter.

          DATA: lv_str   TYPE string,
                lt_split_table TYPE TABLE OF string,
                ls_split_table TYPE string.

          SPLIT lv_json AT '[' INTO str1 str2.
          SPLIT str2 AT ']' INTO TABLE lt_split_table.

          LOOP AT lt_split_table INTO ls_split_table.
            IF sy-tabix <> sy-tfill.       "The last line is not involved in splicing
              CONCATENATE str3 ls_split_table  INTO str3 .
            ENDIF.
          ENDLOOP.

          CONCATENATE '[' str3 ']' INTO o_return5 .

This splits str2 according to ‘] ‘, then removes the last one and splits it together.
This is one way to SPLIT a SPLIT from the right.

Definition of bracket type in typescript

The following figure defines a type Data that can contain a single field pointing to arbitrary Data:

https://stackoverflow.com/questions/58090665/typescript-what-is-the-type-of-the-object-name-string-string

    class aa{
      constructor(headers?: string | { [name: string]: string | string[]; }){
        
      }
    }


Meaning:
The headers type can be one of two types:

    string An object with a field pointing to a string or an array of strings. The name of the field doesn’t matter, there’s no restriction, as long as the field is a string.

display:inline-block Solution to the gap problem

We often use display:inline-block in web layouts; The advantage is that you can arrange block elements as inline elements and set the width and height. Personal feeling is very easy to use, but with more slowly came the problem?
1.display:inline-block; Not compatible in IE6/7
Display :inline-block; *dsiplay:inline; *zoom:1;
2.display:inline-block; There will be an unknown gap (4px)
Reason: A newline or space can take up space and create a gap,
Solutions:
1. Remove whitespace or newline from the current element in the HTML code. This method is too cumbersome and affects the readability of the HTML code.
Font-size :0; font-size:0; font-size:0; This is essentially the same as the 1 method, but may not be supported in Chorme
3. Set letter-spaceing:-4px in the parent element of the current element; The effect is to control the horizontal distance between the text, allowing the text to overlap horizontally (line-height is the text to overlap vertically), thus cancelling out space space or newlines.
Conclusions are as follows:
» the inline – after the block, block level elements IE6/7 no newline gap problem, other browsers have;
» after the inline – block, the level of the inline elements, all major browsers have a newline/space gap problem;
> font-size:0; font-size:0; font-size:0; font-size:0; font-size:0; font-size:0;
» spacing is removed from all browsers by the let-spacing negative value. However, Opera’s spacing limit is 1 pixel. 0 pixels will bounce back and the spacing will be restored.
Recommended solutions:
Font-size :0; letter-spaceing:-4px;
