On the one hand, it is of course convenient, any language version of what is

VB6 coding specifications for the project team ---- VB6 coding Specification This code specification is formulated to facilitate maintenance and development, as well as to reduce detours for subsequent maintenance personnel.This specification is an entertainment edition specification. Before reading the coding rules, consider the following questions. If you do not know the answer, search online.To deepen me

database, often fill in the path of the database, we can use a variable to save the database path. Suppose that the database and the program are stored in the same folder, you can use App.Path to get its path. Note that when the program is placed in the root directory (for example, the C packing directory), App.Path returns "c:/", when the program is placed under a sub-folder (such as c:/db), then return "c:/db", and finally a symbol "/" is missing. I usually use the following methods to solve.

VB6 converts MHT to Doc. in the previous article, only word can be produced. Although the suffix of Doc is actually MHT encoding, uploading to Baidu Library will encounter document recognition errors, below we will use VB6 to convert the document.
