Before I came on to work for my employer, he had outsourced the work of developing a DLL for the project to a company that is no longer capable of supporting it since the individual working for THEM recently quit and no one else is capable of figuring it out.\n\nMy employer has recently upgraded our hardware, so even worse - the DLL that Company furnished us with is no longer useful either.\n\nFurther exacerbated by the fact that the company who released to us the NEW hardware did not release to us a DLL file which is capable of running in VB6.\n\nIt now falls to me to create a DLL file ( NOT a device driver ) which is capable of facilitating communications between the new ( and hopefully the old ) devices and VB6 applications.\n\nMy knowledge of VB6 is... limited, at best. I am mostly familiar with .Net and have had much success in creating DLLs in .Net, but when it comes to VB6, I know enough to get by. I'm entering into uncharted territory here.\n\nI'm well acquainted with the HID.dll and the SetupAPI.dll P/Invokes and structs necessary to make this work, and I was even fortunate enough to stumble upon this, which had a working bit of VB6 code which facilitates read/writing to/from HIDs connected to the system. I tested this and ( with a bit of fidgeting ) it worked for our device out of the box. But that doesn't help me because I can't compile the module into a DLL file ( let alone figuring out events in VB6 and a truck load of other things, but I'm getting ahead of myself ).\n\nI've read and tried a few different methods and while they proved promising, they didn't work.\n\nGoogle has also inundated me with a lot of red herrings and been in general not very helpful.\n\nIf necessary, I would even write it in C/C++ ( though I'd rather not if there is some other way ).\n\nSo is what I am trying to do possible? Can someone direct me to some step-by-step for this sort of thing?\n\nEDIT 1 :\n\nTo expound a bit, when I say that \"they didn't work\", what I mean is that in the case of the first link, the program still failed to find the function ( with an error message like \"Function entry point not found\" ) and in the second case I consistently and repeatedly received a memory write error when trying to call the function ( not fun )." ]

It seems odd that the forward fill doesn't work here, but if I were to just do resampled = df.resample('5T').ffill(), that would work for every column (but is undesired here as it would do so for the value column as well). The closest I have come is to individually run resampling for each column and apply the function I want:\nresampled = pd.DataFrame()\n\nd = {'user':'ffill',\n 'value':'sum',\n 'total':'ffill'}\n\nfor k, v in d.items():\n resampled[k] = df[k].resample('5T').apply(v)\n\nThis works, but feels silly given that it adds extra iteration and uses the dictionary I am trying to pass to agg!
