HOW TO CONNECT VB TO EXCEL?

Referencing the Microsoft Excel Type Library in the project:

from"Engineering"menu"References"Column; Select Microsoft Excel Object Library (Excel2000), and then select"OK"。Indicates that the excel type library is to be referenced in the project.

2. Define excel objects in the declaration process of generic objects:

dim xlbook as

dim xlsheet as

3. Common commands to operate excel sheets in the program:

set xlbook = "File name") 'Open an existing excel workbook file.

true 'Set excel object visible (or invisible) set xlsheet="Table name") 'Set up an active worksheet.

col) = value'Assign a value to the cell (row, col).

Print the worksheet.

true) 'Close the workbook.

End excel object.

This is my collection, you try it.

In Excel, I use VBA to write**, absolutely seamless.

1. Nuget: Many excel development packages don't even need to install office...Both. Of course, there is also an officeobjectlibrary...

2. Use macros in excel 3. Use excel as a data source and use it as a database.

With the development of information technology, especially the need for network information exchange, there is a need for fast information query technology. VB can access Excel documents in a variety of ways [1,2] to meet the requirements of various information queries. This article discusses three ways that VB can access Excel:

1. Directly call the excel application object for access; 2. Access Excel through DataAccessObject (DAO); 3. Access Excel through ActiveX DataObject (ADO). To facilitate discussion, there is a "C: MyDocument" document, which has fields such as "Name", "Language", etc., and several records.

VB directly calls Excel application objects for accessUsing ActiveX technology, VB directly calls Excel application objects, which can realize the call of up to 128 different objects such as worksheets, text boxes, charts, pivot tables, etc. To apply this access technology, the system should have a Microsoft Excel application installed and referenced in the IDE (Integrated Development Environment) environment of VBThis article is 2 pages in total).

There's VBA in Excel.,You find a seam to show me.。。。

Do you want a VB program to read and write excel sheets? I haven't done it before, so I can have it at once, right?

The VB itself provides an automated function that can read and write excel sheets, and the method is as follows:

1. Refer to the Microsoft Excel type library in the project

from"Engineering"menu"References"Column; Select Microsoft Excel Object Library (Excel2000), and then select"OK"。It means that the excel type library of Xiranyin should be referenced in the project.

2. Define excel objects in the declaration process of generic objects:

dim xlbook as

dim xlsheet as

3. Common commands to operate excel sheets in the program:

set xlbook = "File name"Open the Excel workbook file where the paragraph already exists.

true 'Make excel objects visible (or invisible).

set xlsheet = "Table name"Open Feast).'Set up an active worksheet.

col) = value'Assign a value to the cell (row, col).

Print the worksheet.

true) 'Close the workbook.

End excel object.

xlautoopen) 'Run the excel startup macro.

xlautoclose) 'Run excel to close the macro.

4. When using the above VB command to operate the excel sheet, unless the Excel object is not visible, the VB program can continue to perform other operations, and can also close the Excel, and can also operate the Excel. However, when the Excel object is closed during the Excel operation, the VB program cannot know about it, and if the Excel object is used at this time, the VB program will produce an automation error. The VB program cannot fully control the situation of Excel, making VB disconnected from Excel.

Two files? Or two worksheets in the same file? Or is it in the same worksheet?

Tricks for the same worksheet:

Select B2:D6 to copy this area, select B2, right-click to paste it in Paste, select Transpose, OK, and you're done.

vba**：

sub zz()

dim arr

arr = range("b2:d6"Early Draft).value 'Extract data for regions.

ragne("b2:d6").clearcontents 'Clear the data in the original data region.

range("b2").resize(ubound(arr, 2), ubound(arr)) 'Write the data you requested.

end sub

Just run this macro and you're done.

I don't understand, just hi my sails high.

Method steps.

Open the VB software, create a project, and create a form.

Select Menur in the Tools menu, then Menu, after the menu, select the Menu button to select the menu and enter the **window, private sub swflb click()set xlsheet ="Hydrological classification table")end sub

After the following**, you can open Excel**.

Write a macro and let it execute automatically every time you open a file, the macro has the function you said, and hide the macro and set the password to enter the macro.
