xllRegister method
hi. I'm still trying to use xll files to be able to use c++ code for custom
excel functions. No one seems to be fielding these questions, but I thought I'd try again. I'm trying to use the xllregister method in vba to call functions in an xll file. here is the code: sub main() Application.registerxll "filename.xll" Dim c As integer c = AddTwo(8,9) .... End Sub I get an error message "sub or function not defined" The addtwo function from my xll works fine when used in excel. Any thoughts? I'm pretty much out of my league at this point, but I have to get this done for work. Pls help. |

xllRegister method
Are you saying registerxll fails. AFAIK you only need to register it once so
if your function works in Excel I guess it should work in VBA, though you need ExecuteExcel4Macro and the right syntax (following might not be right) c = Application.ExecuteExcel4Macro("AddTwo(" & 8 & "," & 9 & ")") Regards, Peter T "JacksonRJones" wrote in message ... hi.

Thanks a million. It worked and now I get to go home on a positive note

xllRegister method
Apparently you can also use the Run method as well (not tested by me):
Syntax 1: Runs a macro or calls a function. This can be used to run a macro written in Visual Basic or the Microsoft Excel 4.0 macro language, or to run a function in a DLL or XLL. Syntax 2: Runs the Microsoft Excel 4.0 macro at this location. The range must be on a macro sheet. Syntax 1 expression.Run(Macro, Arg1, Arg2, ...) Syntax 2 expression.Run(Arg1, Arg2, ...) expression Optional for Application, required for Range. An expression that returns the application that contains the macro, or a range on a macro sheet that contains a Microsoft Excel 4.0 macro. Macro Required Variant for Syntax 1 (not used with Syntax 2). The macro to run. This can be either a string with the macro name, a Range object indicating where the function is, or a register ID for a registered DLL (XLL) function. If a string is used, the string will be evaluated in the context of the active sheet. Arg1, Arg2, ... Optional Variant. The arguments that should be passed to the function. Remarks You cannot use named arguments with this method. Arguments must be passed by position. The Run method returns whatever the called macro returns. Objects passed as arguments to the macro are converted to values (by applying the Value property to the object). This means that you cannot pass objects to macros by using the Run method. Run Method Example This example shows how to call the function macro My_Func_Sum, which is defined on the macro sheet Mycustom.xlm (the macro sheet must be open). The function takes two numeric arguments (1 and 5, in this example). mySum = Application.Run("MYCUSTOM.XLM!My_Func_Sum", 1, 5) MsgBox "Macro result: " & mySum |
