Environment: Windows Server 2003 In the language and region settings, the region has been set to the United States, and the date format is "mm/DD/YYYY". However, in the Active x dll of VB6, the format $ (now, "Short date") the date format is always "DD/MM/YYYY", which cannot be understood. Using ASP, a simple EXE is made with VB6.Program, The displayed formatted date format is correct, that is, the DLL doe

The program compiled with VB6 10 years ago will be continuously used for repair, modification, and modification, and will continue to be used for several years. I recently took over this program, except for the "sad reminder", I really cannot come up with other words to describe my mood. A little nonsense. Recently, it took some time to call the stored procedure and finally solved the problem. I posted the result. If someone else is using

I wrote a log about VB6.ProgramThe question of running in Windows 7 (http://www.dingcrown.com/soft/blog/Log? /ID/28.html ). So what should I do if I want to develop VB6 in Windows 7? First, unlike Vista, Windows 7 can be installed via acmsetup. Install a dual system. In fact, Windows 7 has provided a solution called Windows XP mode, which can be used with Micrsoft Virtual PC to solve the problem of running

This article describes how you can create a database directly in your program without using access, and then read the data from a standard ASCII text file into the database. The original is a Microsoft Knowledge Base article, but was written for VB3, so the code is a bit outdated. For example, there is no Table object in the DAO now, instead of a Recordset object. The following is the modified code, which is debugged in VB6. First, add the Microsoftd

Comparison | key word | function VB. NET vs. VB6: deactivated keywords and functions The development of history is a process of continuous sublation, VB. NET is the same. It does not hesitate to delete a number of keywords and functions, many of which are many VB6 programmers will never miss. For example, a Deftype statement that has been deleted. This statement is a throwback to FORTRAN, allowing develope

loaded into that memory and the memory address is loaded into the stack for a common CPU execution. This well-allocated address handle is the instance handle of this class. That's what a class pointer really stores.When invoking a property, method, or event of a variable, it is actually the CPU that executes the compiled location code according to the code register and the internal jump, and each instance has a separate block of memory, even though the structure has been, but the content is dif

The precision of a double type is indeed the highest in a definable type, but a valid number is 15 or 16 bitsAnother decimal data type valid bit can reach 28 or 29 bits, but does not contain exponential bitsShould be able to understand this:Decimal precision is higher but the range of numbers is small; double insteadand the decimal data type can only be used in a variant, that is, you cannot declare a variable to be of type decimalThere's a master here that gives you a way to solve an example us

process of this program is probably: first execute attachconsole (-1), that is, attaching the parent process. If the double-click is turned on, Attachconsole (-1) will fail and return false, then the call AllocConsole is executed later. If the command line is called, then Attachconsole (-1) succeeds and returns True, so the subsequent call allocconsole is not executed.The principle is very simple, now generate EXE, run on the command line to see if the title has been changed to my Console also

The project is saved in the installation directory ("C:\Program Files (x86) \microsoft Visual Studio\vb98\errhandler1.vbp").File Manager can not find this file, the VB menu opens the File List dialog box to find this file, the file has a lock.It's strange to see the file property owner. Tip cannot display all current people.Files can be deleted.It is forbidden to write this directory without administrator privileges. It seems to have been written, but only in the

Generally, the control styles provided by VB cannot meet your needs. Therefore, you need to change the control styles frequently. If many controls are required for the project, in order to unify the control styles, you need to copy controls frequently to ensure the uniformity of styles. Therefore, to synchronize the styles of controls, Program There will be a lot of work, and the design style can not be retained, so we can use the add-ins function of VB6
