问题 I am trying to write a list of lists into an excel sheet using pandas the list looks like: List_of Lists = [ [1,2,3,4], [5,6,7,8], [9,10,11,12], ........, ] The number of these lists inside the main list could go up to a 1000. I also want to label them like colums1, colomns2, until colums100 for instance. on the same sheets. can anyone familiar with pandas help me? as this could be really easy for some? 回答1: I believe you can just pass the list into pd.DataFrame() and you will just get NaNs

How do I declare a function in VBA which accepts arguments of type XlfOper (LPXLOPER)?

由 心不动则不痛 提交于 2019-12-23 23:26:49
问题 I have found out in the answer to a previous question a way to call a function defined in a (C++) xll without registering it. I was previously using the registering infrastructure provided by XLW and I was using the XlfOper type to pass the arguments between VBA and the xll. The c++ function goes like this: extern "C" { LPXLOPER EXCEL_EXPORT a_function(XlfOper arg1, XlfOper arg2); } Following the answer to my previous solution, I am directly declaring the function, something like that:

How do I call a function from an xll add-in which could not be registered to the function wizard?

由 ≡放荡痞女 提交于 2019-12-11 09:05:00
问题 I have an xll (a rather complex c++ project) exporting a function which, for historical reasons, takes a large number of arguments, and precisely 20 . This is a magic number: apparently in Excel 2003 there is a maximum number of 30 arguments (" In Microsoft Office Excel 2003, the maximum number of arguments that any function can take is 30, although most take fewer than this. "), but over 20 the function cannot be registered in the function wizard. Now, as it happens and as you could guess, I

C++ Excel Add-in loading error: XLL file is loaded by Excel as text file

问题 I'm building XLL add-ins for Excel, using C++ and XLW library. It works fine on my PC, and on many others. But in some cases, when I drag the XLL into a new Excel window, this error shows up: The file you are trying to open, 'my_addin.xll', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now? If click yes , then Excel will open the XLL as a text file, showing

I believe you can just pass the list into pd.DataFrame() and you will just get NaNs for the values that don't exist. For example: List_of_Lists = [[1,2,3,4], [5,6,7], [9,10], [11]] df = pd
