Updating excel from access
Then browse to folder C:\WINNT\system32 and select file Simple and click Open.
After done, Simple Calc will appear in your reference list and you need to move down in the list to find and check it. You may remember in the registry screenshot above, there is a DLL path value in Code Base entry.
Here is what is registered in Windows registry for the compiled assembly so that COM clients can use the . Note that the path to the DLL is stored in Code Base entry. Windows system folder C:\WINNT\system32 is the default location for DLLs and type libraries so we copy type library Simple to it. In the menu cross the top, click Tools - References...
To register the assembly on other computers such as production machines, you can register the assembly by using Reg When the References window is opened, click the button Browse.
VBA will use this registry information to find which DLL to call.
In our case, it's D:\CSharp\Simple Calc\Simple Calc\bin\Release\Simple 7. To use the variables and methods in the C# DLL, we need to call the DLL inside VBA.
Net is not that hard as long as you have object oriented programming experience or knowledge.
Enter any comments that you wish for the project coordinators to see when approving your request, for example what role you would like to have in the project.
On the Assembly Information window, check Make assembly COM-Visible. This allows COM-based applications to call the class library's member variables and methods. There are a few ways to do it based on your circumstances.
Applications created in VB or VBA are COM-based applications. For a development machine, we can check "Register for COM Interop" setting in Visual Studio. Then check Register for COM Interop (Based on your version of Visual Studio, it could be on a different tab). Depends on whether your build is a Debug or Release build, you can find the DLL and type library file in either Debug or Release folder under the bin directory.
Add a button to the Access form and then add a click event to it. Net DLL by creating a new object from Calc class and then call its methods.
In the click event we call a function called test() which is created within a VBA module. If we debug and step through the test function, we will see the result is 9 as it's calculated inside the C# DLL and returned to VBA. The limitation in this article is that Visual Studio registered our DLL and type library automatically for our development machine only.You can find a working example using PHPExcel to generate an Excel file at https://github.com/kaspernj/php_process/blob/master/examples/example_ Current release PHPExcel 1.7.2 Production, check the changelog for details!
