Xll File Is Not A Valid Add-In

Creating Excel Add in with VB. C. Two weeks ago, I was asked by a user to provide access to some data of one of their database so that they can use it directly from Excel. I first suggested some methods that are already implemented in the application like extracting the data and use it in a lookup table. But nothing could satisfy him. He has one idea in mind being able to use a formula to have access to the data ie Get. Datavalue. 1, value.

It was time for me to dig into the creation of an add in which I knew it was possible but I never built. So guess what is my article all about this monthHi, Check for two things 1. Has the Excel addin been installed correctly. Enter 123 in cell A1. In cell B1, enter NBTEXTA1. Do you see the number being spelled.

The demo code is provided in both VB and C. It was built using Visual Studio 2. I have tested the add in against Office 2. Is VSTO requiredAt first, I thought that VSTO Visual Studio Tools for Office was required to create that kind of interaction between a Visual Studio component and Office applications. But for what we will build here, you dont. Plain old Visual Studio is all you need. The component we will create will be a library of functions. The add ins we will create here will be found under Automation Add ins in Excel. Creating the project. The really first thing we need to do is to create a new Class Library project as shown in figure 1. This is the same kind of project you surely have already created in the past to create a DLL for use in your application. Figure 1 the creation of the library of functions. Now that the project is created, rename the generic empty class Class. I named mine EMFunctions. A single project used as an add in may contain multiple classes as any other class library. There is no limitation here. Because we will want to use this component from within Excel, we have to set special properties that we normally dont. One thing I found that I dont really understand the full impact is that add ins only seems to work if your configuration is using the Release mode. So better switch right now to this configuration. Even if you are in Release mode, debugging will be available. Open the project properties by double clicking My Project in the Solution Explorer and make sure that the Application tab is selected. Now click the Assembly Information button to open the dialog of the same name and check the Make assembly COM Visible as shown in figure 2. This is required since Excel still rely on COM to communicate with components. You can also set other properties such as the title. GUID. Finally click the OK button to close this dialog. Figure 2 Check the Make assembly COM Visible. Now open the Compile tab and check the Register for COM Interop option which is completely at the bottom as shown in figure 3. Figure 3 Check Register for COM Interop. We also need to add some references. So open the References tab, click the Add button and go to the COM tab of the Add References dialog. From the list of components, select these 2. Microsoft Excel xx Object Library. Microsoft Office xx Object Library. The xx here represents the version. Since you may have multiple versions of those libraries in your list, select the higher versions. Figure 4 The References. If you will need to use the Excel objects worksheets, range, cell,. Net tab. Microsoft. Office. Tools. Common. Microsoft. Office. Tools. Excel. One last thing we need to do in the project properties is to sign the assembly so that the user wont have to lower the security. Excel to be able to use our add in. This can be done by opening the Signing tab, checking Signing the assembly. From the Choose a strong name key file combo, either select an existing file you have or create a new one. Figure 5 Signing the assembly. Having marked the component has COM visible is not enough to have the code available to Excel. There is some specific code to add to the classes you will want to expose. Open your class remember mine is called EMFunctions. Public Class EMFunctions. The very first thing we need to do with this class declaration is to mark this specific class as visible for COM by changing. COM, only those that requires it. Imports System. Runtime. Interop. Services. Imports WIN3. 2 Microsoft. Win. 32. lt Class. InterfaceClass. Interface. Type. Auto. Dual, Com. VisibleTrue. Public Class EMFunctions. Then, to the classes that are visible to COM, we need to add some code that will automatically be called to register and unregister the class. Com. Register. Function. Attribute. Public Shared Sub Register. FunctionBy. Val p. Type As Type. WIN3. Registry. Classes. Root. Create. Sub. KeyGet. Subkey. Namep. Type. lt Com. Unregister. Function. Attribute. Public Shared Sub Unregister. FunctionBy. Val p. Type As Type. WIN3. Registry. Classes. Root. Delete. Sub. KeyGet. Subkey. Namep. Type, False. Private Shared Function Get. Subkey. NameBy. Val p. Type As Type As String. Return CLSID p. Type. GUID. To. String. To. Upper Programmable. The important things here are the attributes that are doing all the hard stuff. They tell. Net to call those functions when the assembly is registered. The public methods. The plumbing is now all done. We havent written anything fun yet. Now consider this code. Public Function Get. Population. By. IDBy. Val p. ID As Integer As Integer. Dim ds As Data. Set c. Shared. Create. Data. Set. Dim drs As Data. Row ds. TablesStates. SelectString. FormatID 0, p. ID. If drs. Count 1 Then. Return Convert. To. Int. 32drs0. ItemPopulation. Return 0. What this code does is that it receives an ID as an argument, use this argument to search into a dataset and if found, it returns the population. Long time readers will recognize my famous dataset that I have been using for a long time containing countries, states and the population for some states. Is there anything in that code that relates to Excel or that let us think that it will be called by Excel Absolutely not. You could even use this method from a regular. Net application. Testing the project locally. It is now the time to start testing what we have done so far. It can be easily done by having Excel starting when we hit F5. To configure this behaviour, open the project properties by double clicking the My Project item in the solution explorer. Then, open the debug tab and set the start action to Start external program. Finally, find Excel. This is what is shown in figure 6. Figure 6 Setting Excel as the startup application. You are now ready to press F5. Most of you will probably be disappointed at this point because you will get this error. Cannot register assembly C dataArticlesUT2. Excel Add inEMoreau. Demo. XLAddinEMoreau. Demo. XLAddinbinDebugEMoreau. Demo. XLAddin. dll access denied. Please make sure youre running the application as administrator. Access to the registry key HKEYCLASSESROOTEMoreau. Demo. XLAddin. c. Shared is denied. This error has nothing to do with the code. It is only because very special permissions are required in order to register the DLL. Close Visual Studio and reopen it with the administrator privileges. To do this, find Visual Studio in the Start menu, right click on it and choose Run as Administrator. Now reopen your solution. When you now hit F5, the project compiles and automatically opens Excel. The first time you will run your add in, it wont be available right away in Excel. You need to add it to the list of allowed add ins. Microsoft Excel Wikipedia. Microsoft Excel is a spreadsheet developed by Microsoft for Windows, mac. OS, Android and i. OS. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1. Lotus 1 2 3 as the industry standard for spreadsheets. Excel forms part of Microsoft Office. Features. Basic operation. Microsoft Excel has the basic features of all spreadsheets,4 using a grid of cells arranged in numbered rows and letter named columns to organize data manipulations like arithmetic operations. It has a battery of supplied functions to answer statistical, engineering and financial needs. In addition, it can display data as line graphs, histograms and charts, and with a very limited three dimensional graphical display. It allows sectioning of data to view its dependencies on various factors for different perspectives using pivot tables and the scenario manager. It has a programming aspect, Visual Basic for Applications, allowing the user to employ a wide variety of numerical methods, for example, for solving differential equations of mathematical physics,67 and then reporting the results back to the spreadsheet. It also has a variety of interactive features allowing user interfaces that can completely hide the spreadsheet from the user, so the spreadsheet presents itself as a so called application, or decision support system DSS, via a custom designed user interface, for example, a stock analyzer,8 or in general, as a design tool that asks the user questions and provides answers and reports. In a more elaborate realization, an Excel application can automatically poll external databases and measuring instruments using an update schedule,1. Word report or Power. Point slide show, and e mail these presentations on a regular basis to a list of participants. Excel was not designed to be used as a database. Use of a user defined function sqx in Microsoft Excel. The named variables x y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel. Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y. Graph made using Microsoft Excel. Microsoft allows for a number of optional command line switches to control the manner in which Excel starts. Macro programming. VBA programming. The Windows version of Excel supports programming through Microsofts Visual Basic for Applications VBA, which is a dialect of Visual Basic. Programming with VBA allows spreadsheet manipulation that is awkward or impossible with standard spreadsheet techniques. Programmers may write code directly using the Visual Basic Editor VBE, which includes a window for writing code, debugging code, and code module organization environment. The user can implement numerical methods as well as automating tasks such as formatting or data organization in VBA1. VBA was removed from Mac Excel 2. VBA engine natively to Mac OS X. VBA was restored in the next version, Mac Excel 2. Active. X objects, impacting some high level developer tools. A common and easy way to generate VBA code is by using the Macro Recorder. The Macro Recorder records actions of the user and generates VBA code in the form of a macro. These actions can then be repeated automatically by running the macro. The macros can also be linked to different trigger types like keyboard shortcuts, a command button or a graphic. The actions in the macro can be executed from these trigger types or from the generic toolbar options. The VBA code of the macro can also be edited in the VBE. Certain features such as loop functions and screen prompts by their own properties, and some graphical display items, cannot be recorded, but must be entered into the VBA module directly by the programmer. Advanced users can employ user prompts to create an interactive program, or react to events such as sheets being loaded or changed. Macro Recorded code may not be compatible between Excel versions. Some code that is used in Excel 2. Excel 2. 00. 3. Making a Macro that changes the cell colors and making changes to other aspects of cells may not be backward compatible. VBA code interacts with the spreadsheet through the Excel Object Model,1. User created VBA subroutines execute these actions and operate like macros generated using the macro recorder, but are more flexible and efficient. History. From its first version Excel supported end user programming of macros automation of repetitive tasks and user defined functions extension of Excels built in function library. In early versions of Excel these programs were written in a macro language whose statements had formula syntax and resided in the cells of special purpose macro sheets stored with file extension. XLM in Windows. XLM was the default macro language for Excel through Excel 4. Beginning with version 5. Ns Virtual Dj Skins. Excel recorded macros in VBA by default but with version 5. XLM recording was still allowed as an option. After version 5. 0 that option was discontinued. All versions of Excel, including Excel 2. XLM macro, though Microsoft discourages their use. Charts. Excel supports charts, graphs, or histograms generated from specified groups of cells. The generated graphic component can either be embedded within the current sheet, or added as a separate object. These displays are dynamically updated if the content of cells change. For example, suppose that the important design requirements are displayed visually then, in response to a users change in trial values for parameters, the curves describing the design change shape, and their points of intersection shift, assisting the selection of the best design.

Microsoft Excel up until 2. Excel Binary File Format. XLS as its primary format. Excel 2. 00. 7 uses Office Open XML as its primary file format, an XML based format that followed after a previous XML based format called XML Spreadsheet XMLSS, first introduced in Excel 2. Although supporting and encouraging the use of new XML based formats as replacements, Excel 2. In addition, most versions of Microsoft Excel can read CSV, DBF, SYLK, DIF, and other legacy formats. Support for some older file formats was removed in Excel 2. The file formats were mainly from DOS based programs. Binary. Open. Office. Excel format. 2. 7 Since then Microsoft made the Excel binary format specification available to freely download. XML Spreadsheet. The XML Spreadsheet format introduced in Excel 2. XML based format missing some more advanced features like storage of VBA macros. Though the intended file extension for this format is. XML files with. xls extension. This feature is widely used by third party applications e. My. SQL Query Browser to offer export to Excel capabilities without implementing binary file format. The following example will be correctly opened by Excel if saved either as Book.
