Data | Database A lot of brothers here ask questions about VB6 reading and writing to a database, and here's an example that I hope is inspiring. 1, with names and related pictures as an example, the database is access, with the following fields: Name char,picture OLE object,filelength number. When you are MS SQL, change the picture to lob. 2, the example contains Control:commom Dialog,picture,listbox. The source code is as follows: Option Explicit P

For Google and csdn, there is no correct and rigorous VB6 to determine whether the string contains Chinese characters, or simply to determine whether the ASC () return value is less than 0 (this can only determine whether it is a double byte string, such as Korean, Japanese, Chinese, and Arabic. It cannot be determined as Chinese. It is not rigorous to judge Chinese characters.It is better to give a more rigorous method to determine whether or not it

Today, my brother found an interesting phenomenon when debugging the program. The system prompts "circular relationship between modules". Let's look at the sample code below: 'CD Option explicit Public event clickevent () Public withevents C as CE Public sub click () Raiseevent clickevent End sub Private sub c_clickevent () ' End sub 'Ce Option explicit Public event clickevent () Public withevents C as CD Public sub click () Raiseevent clickevent End sub Private sub c_clickevent () ' En

The XML schema language is the standard for verifying the XML document format. You can use XML schema in VB6 to verify the validity of XML. This example demonstrates how to use Microsoft XML Parser 4.0 to verify XML files. First, create a file named wellformed. XSD and add the following code to it: Xmlns = "http://tempuri.org/WellFormed.xsd"Xmlns: xs = "http://www.w3.org/2001/XMLSchema"Attributeformdefault = "qualified"Elementformdefault = "qualified"

You need to use VB6 to read network card network management information and set it. So I found a piece of code that uses WMI's system query method to loop through all network adapters and obtain information. Of course, you can add judgment and processing.

Use VB6 to create a toolbar. If you use the toolbar wizard, it will clear the key attribute of the button style attribute value in the toolbar that you have set to 3-tbrseparator. The solution is to use 4-placeholder instead of 3-tbrseparator, get the same running appearance, and do not lose the key attribute value when using the toolbar wizard. I just found that if I set it to 4-placeholder without setting image indexes, the buttons will be lost whe

I have been hiding from the first day, and I have to skip the 15th day. I finally want to upgrade a VB6 project to VB. NET. On my colleague's computer, there is no problem with the upgrade. But on my computer, the upgrade process seems to be quite smooth, that is, when the upgrade is almost complete, the project file cannot be opened, the project file is named. vbproj. vs7.vbproj. Open this file in vs2008 and prompt to upgrade. Okay, continue to upgra

VB6 allows you to easily compile OCX controls and DLL components. To use DLL components on your website, you can directly use Server in ASP. createObject ("project name. you can call this component on the server. The use of OCX is complicated because it needs to be downloaded to the client. The following are some of my experiences:Pack OCX into an internet package:Start package: Choose "external program"> "external program manager&
