Excel VBA Code: Compile Error in x64 Version ('PtrSafe' attribute required)

Solution 1

I think all you need to do for your function is just add PtrSafe: i.e. the first line of your first function should look like this:

Private Declare PtrSafe Function swe_azalt Lib "swedll32.dll" ......

Solution 2

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

From: http://technet.microsoft.com/en-us/library/ee681792.aspx:

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

I am using Win8 x64 + Office 2013 x64.

MY PROBLEM:

I have an excel file, which has some modules in it, and works flawlessly in Office (Excel) x86. It uses the Swiss Ephemeris file (swedll32.dll) to do a lot of astronomical calculations.

However, when I try to run it on my end, which is on Excel x64, ASAP it's opened, the VBA editor fires up and gives me the following error:

Compile error:
The code in this project must be updated for use on 64-bit systems.
Please review and update Declare statements and then mark them with the PtrSafe attribute.

As I said above, it works only in 32bit office (Excel) but it won't work in my x64 Excel However there seems to be a workaround but I am too much of a novice to get it.

I am no good in VBA, however, after digging over the Internet, a few websites proposed that for 64bit office (Excel), we should amend (for each declaration) the codes to something like that:

Original Statement: Private Declare Function
Amended Statement: Private Declare PtrSafe Function

Unfortunately, after adding 'PtrSafe' everywhere, though the VBA errors stopped, but the values are not being displayed/calculated properly in the cells.

From a post on 64 Bit in VBA from Microsoft, it would seem that we also need to modify some of the data types such as:

Long → to → LongPtr
LongPtr → to → LongLong
and some "Long" are supposed to remain the same, depending on what they do.

This website (under "Which Longs should become LongPtr?") gives a clue though, as to how to know which one to modify.

I do not understand a thing about it and have no idea what should be done really to make this work in Office (Excel) x64. Someone who is pretty good at this, kindly please help me. Please.

note:

Only the declarations that appeared in red, denoting that they contain errors have been dumped here. The remaining portion of the codes were not pasted here because they appear fine (green colored).
For the Excel file to work properly on your computer, ensure that both the 'swedll32.dll' & the 'JCalc Ver 0.2d.xls' are in the same folder, after having extracting them.

I have the 64bit compiled DLL (swedll.dll) as you are suggesting. But it wouldn't work well unless changes are made in the declarations by adding the PtrSafe attribute as well as some data types are modded (without modifying the data types, though the runtime errors are gone when PtrSafe are added to the declaration statements, but the values don't get computed well in the cells).

Ok, I thought you were trying the 32Bit version in Office 64Bit. I'll have a look to see if I can get the 64Bit version working.
user2422957 almost 11 years

I'm sorry, I forgot to precise this: This link bit.ly/Z8Kqm9 contains the 32Bit version of swedll32.dll + the .xls file. However if you would like to download the 64bit version of the same dll only, it's downloadable here. Note: Both the 64 & 32 bit DLL files have the same names, i.e., swedll32.dll. But their file size are different - the 64bit one is 468KB while the 32bit DLL is 360 KB.
CuberChase almost 11 years

Hey, it can get confusing with so many 32 and 64s floating can't it. I understand what you are saying but I believe the 468kb version is not 64Bit since it runs on office 32Bit (try it yourself). Since a 64Bit DLL will not run on Office 32Bit I think this is your problem.
user2422957 almost 11 years

@CuberBase you wrote: "Since a 64Bit DLL will not run on Office 32Bit I think this is your problem." I have Office 64Bit. It doesn't work here on my computer, the problem is with the VBA declaration statements, which needs to be modified by adding things such as PtrSafe attribute and some data types needs to be changed such as from Long to LongPtr. But I wonder which ones amongst the whole lot in that MainCalculation Module needs to be changed.
CuberChase almost 11 years

The problem you are having at the moment is not due to the declarations. The problem is because the DLL you think is 64Bit is not 64Bit (again, you can check this by specifying it in your workbook and running it in Office 32Bit - it will work). If it was a 64Bit file then the declaration changes you specify would be adequate.
user2422957 almost 11 years

you told me earlier: Run-time error '48' File not found: swedll32.dll. Based from the run time error, it seems that it couldn't find the file. Just wanted to ask you, where did you kept that swedll32.dll? It should be in the same folder as the *.xls file and a copy should be in C:\Windows\System32. Thanks for your inputs.
CuberChase almost 11 years

I only got the Run-time error when trying the '64Bit' DLL on the 64Bit Office. For all cases, I specified the exact path to the file - you can then place it anywhere. This worked fine for both DLLs on 32Bit Office. I'm guessing that it gives the '48' error because the file is not valid since there are other file not found errors with different numbers. Good luck!

This is perfect, thank you! One quick note, I believe certain data types also need to be updated. For instance I think "ms" needs to be updated to "millisecs"
