have been using VB6 to write software, but the recent system to do the Web version, but the previous business rules are all in the code to write dead, no use of the storage process, if the web-side rewrite rules, the workload is too large, project time is not allowed, had to transfer business rules to vb.net. Now the vb.net version is not supported from the VB6 transfer, but you can directly copy the busine

According to the information found on the internet, Ms has a component that can be used to support VB6 to access the soap interface. After installing mssoaptoolkit.exe and trying it, I found that the WebService written in C # Or VB.net can be accessed. However, if the interface is written in other languages, various inexplicable errors may occur, such as incorrect parameter types or initialization failures (which should be caused by parsing the WSDL m

Search online for information about how to use C # To develop ActiveX ControlsArticleIt basically seems to be an article in the cited blog Park. But that article is used in IE.

In VB6, we use on error to capture and handle errors, and often use on error resume next to generate possible ignore errors. Will error capture affect the speed? Yes, using error handling will reduce some performance. . Net, using try catch will also affect the performance, so we use When reflector decompile Microsoft's class library, it will find that its sub-processes seldom use try to capture errors. Generally, they use predictable methods to deter

CCW (COM callable wrapper) is a mechanism provided by vs2005. It can export. Net hosted DLL to a traditional com to facilitate VB6 and ASP calls.

Error | Error handling | speed In VB6, we use on error to catch and handle errors, and we often use on error Resume Next to ignore errors that may arise. So does using error trapping affect speed? Yes, using error handling will degrade some of the performance in.

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.

This article describes how to create a database in a program without using Access, and then read data from standard ASCII text files to the database. The original article is an article in the Microsoft Knowledge Base, but it was written for VB3 at the time, so the code here is a bit outdated. For example, if no Table object exists in DAO, replace it with a Recordset object. The following is the modified code, which is successfully debugged in VB6. Add
