Date Published:. File Size:. System Requirements Supported Operating System. If you are a Microsoft Office or Microsoft Office XP user, please obtain a patch for this issue from the Office Update site in addition to installing this patch. You will find a link to OfficeUpdate under the Related Resources links at the right of this page.

Follow all of the steps below to determine which version s of VBA is on your machine: Right click on vbe. For example, after this patch is installed the version of vbe. If the directory is present you also have VBA version 6 installed.

Code will not started and will be emulated by VB Decompiler. We offer 4 different licenses for VB Decompiler: Minimum System Requirements for v8. Code decompilation for the P-Code compiled applications. Recovery pseudo code to the standard Visual Basic instructions with a highest success rate. Decompiling Code. Disassembling Code. Decompiling Forms. HEX Editor. String References. A6 The code stops with the familiar yellow line in the IDE, you can inspect the variables, use the immediate window, and do pretty well anything you can do in VBA except edit the code on the run.

Hover the mouse over the Values , parameter in line 5 and expand the tree to see what its items are:.


This is another catch to be aware when passing values to VB. To know what the original cell type is, we need to pass a reference to the range A1: A6 to the function, not the values of the range. It's time to learn how to receive Excel references. Excel object model via COM, late bound Here is a VBA function that returns the sum of numeric values in a range excluding formula values and date constants.

It uses properties such as. HasFormula and.

Cells If Not cell. For simplicity, let's add this function to the TestFuncs you already have. Later, you'll be starting a new project with more functionality.

The type Range is flagged with green squiggles because it belongs to System. Range which is a completely different VB. Net class which is not referred to in this project.


Without using any Excel type library you need to use the variant Object type for Range and cell. When you fix that, you see a warning on the SumNConstants calculation:. These can be cleaned up by initialising SumNConstants to zero at the start of the function.

However, we are not done yet. Net with no connection to Excel. A first chance exception of type 'System. MissingMemberException' occurred in Microsoft. There are several things to add: It changes the registration type of the function to tell Excel to pass an ExcelDna. ExcelReference if the function is called with a range reference. Otherwise the function would always get the values of the range, not the cell references.

Application object. In VBA you can define a function to receive a Range object and work with that directly. That is not possible with VB. The closest we can get is to use AllowReference to tell Excel to pass a reference but even that is not a Range object; it is a C structure and we have to convert that to a Range by getting its address eg "[TestFuncs. Range method to return a Range object which the function then returns as a generic Object. A side effect to be aware of is that if the function that is registered as IsMacroType: All the above looks rather more awkward compared to the VBA version.

When you dig in to it, you recognise that the C API calls being used here are based on the original XLM macro language still used within defined Names for certain legacy purposes. For example, GET. These macro-sheet functions and commands are documented in the Help file XLMacr8. That should be available from http: Excel XlCall. You can now press F5 to launch and test this solution.

By the way, we can enhance the ReferenceToRange function to handle ranges with several areas. A single XlCall. LastIndexOf "! Range strAddress End Function. The drawback of late binding is that there is no Intellisense and no checking for mistakes at compile time. So you could have a misspelling like this that would only fail at runtime: Ragne "A1". We'll show how to add Intellisense in the next section.

Before we leave this example, let's look at another consequence of not having the Excel types available in DotNet.

VB Decompiler

These are not provided in VB. Net, so we have to use As Object for the types, qualify all the global objects back to the Application object, and define our own constants.

To illustrate some of these concepts, let's add a Sub to the TestFuncs project to do some operations on an Excel sheet. Assuming Excel starts with the default Book1, it should show a message "Sheet1". To add it as a menu button for simpler testing, use: This is the old Excel style menu that appears in the Addins tab of the Ribbon. The shortcut key to that is X, and we have specified X as the menu accelerator and the button shortcut.


So now you can run it just by typing Alt, X, X, X. By default the name is the method name, but you can override with an attribute: When you go to the Macros dialog box and type in "MyMacro", the Run button should become available and then run your macro if you click it. To save having to type ExcelDnaUtil before Application, we can import that at the top. The code now reads Imports ExcelDna. Integration Imports ExcelDna. You can now extend that to try other globals such as: MsgBox Application.

The compiler outputs: Error 1 'xlR1C1' is not declared. It may be inaccessible due to its protection level. If you are pasting in code from VBA you either edit references to globals like "Workbooks" to prefix them with "Application. So the code now looks like: Imports ExcelDna.

Workbooks End Get End Property. Actually, the constants are easily done; just include in your project a copy of the enums downloaded from Mike Alexander's site.

You'll have to change the second xlColorIndex to say xlCI. It takes the VBProject in a workbook and qualifies the xl constants with their enum types, and prefixes ones like ActiveSheet with Application.

Of course, please read the ReadMe. So, let's tackle that problem next. Boilerplate steps for creating a project in VB Express The following projects start in the same way, so I'll give the generic steps here using the term "MyProject" which you can substitute with your own solution name. In the subsequent projects, I refer to these steps as "Create the standard ExcelDna project with the name. Or, you can simply rename this later.

To add it to the project, re-open the project and do: This creates a file Myproject. You can then see this template when creating projects in the future. Stage 3: He provides all the PIAs in this zip: Then in your module use Imports Microsoft. He says "Otherwise, the drawback with the MS PIA is that it has to be installed on the client machine, and there is a different version for each version of Office. This also means you need admin rights to deploy your add-in.

Net version 4. Copy in the following code, similar to that in the TestFuncs example.


Because 'Application' is ambiguous between ExcelDna. ExcelDnaUtil and Microsoft. Excel, create a global helper to point to the current Excel instance via ExcelDna. If you're preparing an addin for migration, changing 1. In this scenario, an application that references an Office PIA can actually run on a computer with an earlier version of Office installed, provided that it does not use any APIs that are new in Office For a related walkthrough, see http: This will only work under.

ActiveWorkbook" etc can be done in VBA and it works just as well. The ExcelApi. Enums need their prefix so you have to use XlReferenceStyle.

However although Intellisense is fine for suggesting methods and properties as you type, it does not detect invalid methods pasted in from other code. UsedRagne will not get flagged as an error until runtime. Integration XlCall, etc Imports Microsoft. Excel Workbook, Range.

ActiveCell ' start with activecell A1 in Sheet1 With cell. Offset 1, 1 ' B2. Address True, True, ReferenceStyle: C5" rg. Version End Sub End Module. Test the project with VB Express with F5.

Vba to Vb Net Xll Add in With Excel Dna

Excel should launch and the menu should be visible. Quit Excel Start Excel , do the same, and it should also work. Obviously, you can't access parts of the object model not present in the version of Excel running. If you need to handle this conditionally, then in the code test for the value of Application.

Simplify deployment by packing the components into one. XLL file. ExcelDnaPack is a command-line utility to pack Excel-Dna add-ins into a single. So in the command window it will appear as warning is from second time output DNA, Name: To test, I copied testpia-packed. When you have time, read the files in the Examples and Tutorials directories. Do the same two things for ExcelApi. Copy in this code, similar to that in the TestFuncs example, but instead of the generic Object type for the variables, we'll use types from NetOffice.

This should look familiar enough to a VBA developer. If you're preparing an addin for migration, changing "As Range" to "As Excel. Range" can be done in VBA and it works just as well. There are some awkward syntax changes; for example, all. Address methods change to. Be careful to change. Offset and. Resize to. The extra line New Excel.

Application Nothing, ExcelDnaUtil. You will also notice that the imported ExcelApi. If you want to use Resume Next, that is only available with the On Error style of error handling. Integration 'Imports ExcelDna. ExcelDnaUtil we have NetOffice. ExcelApi ' For Excel.

Workbook, ws As Excel. Worksheet, rg As Excel. Range, cell As Excel. Range Dim dummy As Excel. StackTrace Debug. Exclamation, ex.

Source End Try End Sub. NetOffice allows version independence with. Net version 2. Range strAddress to get a range from any qualified address.

Be aware that with the ExcelApi. Range type, you MUST change all occurrences of. Offset to. Dim xCell As NetOffice. Range, oCell As Object ws. Range "B2: D4 xCell. Offset ' B2: Enumerations and. Enums module.

Then prefix enumerated constants with their type, eg XlDirection. Characters property gives an error 'Error 16 Class 'NetOffice.

Characters' cannot be indexed because it has no default property. Characters Start: This is a byproduct of the way the default properties are accessed in Netoffice. As of 1. I need Netoffice. Forms, NetOffice. COMObject', which is not a collection type. VBA accepts a variable number of parameters, eg for. Offset you can specify only a row offset and the column offset defaults to 0.

The only one I found irritating was. Address Visual Studio regular expressions: Search for any text followed by a space or bracket then any text followed by. Sort via the PIA needs at least the first key specified; and orientation if you want it sorted top to bottom, eg rg. Sort method in NetOffice was a headache because every possible parameter must be specified, unlike VBA where they can be omitted. Isolate this into its own sub: Cells 1, 2. Sort header: Cells 1, 3 , order1: Cells 1, 2 , order2: Cells 1, 1 , order3: Open This has seventeen parameters.

Net you must specify them all up to that point. You cannot omit them by using two commas in succession. You can pass Nothing for all values except 'format' and 'origin' which must have some real value, eg Workbooks. Open filename: You cannot specify Format: Unable to get the Open property of the Workbooks class.

If you omit the comma, Excel silently errors and the ExcelDna app hangs. Stage 4: Creating an add-in with Ribbon commands The above examples show an old Excel style menu button. It's time to create an addin with a Ribbon button that does more work with Excel. Enter the following test code; we will replace it with real code later.

Edit the standard. Dna and copy in the text below. The CustomUI contains the Ribbon markup which adds a group to the Excel Ribbon with one button with a standard MSO image and an onAction that calls a standard ExcelDna method that in turn calls with no parameter the macro named in the tag.

The ExcelRibbon-derived class must also be marked as ComVisible True , or in the project properties, advanced options, the ComVisible option must be checked. ExcelRibbon End Class. If you use any other onAction procedure than "RunTagMacro", put it inside the Ribbon class because only subs in this class are visible to the Ribbon onAction.

It is also the only way to pass the calling Ribbon control to the sub, for example: Run ctl. Id, ctl. Tag End Sub End Class. Test the project with F5. After enabling the macros, you should see a button to the right of the Review group that displays the test message. If you don't, look at the Ribbon troubleshooting guide. Having got the skeleton right, now we'll add the code to create the TOC. It should look like this:.

Try If Application. Add wsDoc. SpecialCells XlCellType. Cells lRow, lCol. Add Anchor: C69", TextToDisplay: Add anchor: Sheets lSheet. Visible Case XlSheetVisibility.

Value '. Value ' convert to values; remove this if you want it to recalc. Sheets lSheet If. End If Next lSheet wsDoc. Resume Case vbNo, vbIgnore: Resume Next Case Else: On Error GoTo 0 ' restore any screenupdating etc Application. Sheets sName. UsedRange If rg. With StartCell. Find What: Assert Err. Description Debug. Tips and workarounds One of my Excel VBA add-ins had 13, lines of code and took about two weeks full-time equivalent to convert to VB.

Net using Visual Studio , Excel-Dna 0. Bear in mind that the supporting libraries are being constantly updated so check for changes in more recent version of Excel-Dna and NetOffice. The following list of tips and gotchas was built up from that experience. Net much safer. Fix any issues with Option Base 1 and ByRef first. Using Option Base, you can change this to 1.
