Compile Excel To Exe

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. Bloomberg and many others vendors are providing. It was time for me to dig into the creation of an add in which I knew it was possible but I never built. Hey, a Windows update the other day seems to be causing this error in AutoCAD. I think it is only a problem with the 2007 version of Office products that were updated.

Hi all, We are having some trouble with Microsoft Office files using macros. The files can be stored either on a File Server or a Client and we are being. So guess what is my article all about this month 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. Compile Excel To Exe' title='Compile Excel To Exe' />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. Data-File-Converter_23.png' alt='Compile Excel To Exe' title='Compile Excel To Exe' />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. Borland C Builder 6 Portable Browser here. 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.

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.
