4515 :: seek for help on porting VB lib to nim

• oyster (orginal) [2019-01-01T13:22:05+01:00] view original

  in the VB lib, which calls functions in 32bits DLL, there are something I am not very sure

  1. many arguments are declared as LONG in the VB files. I found that LONG is signed 64-bit integers on https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/data-types/long-data-type . But var a:int64 can't be compiled with nim 32bits

  So, what can we use in nim to replace the long in VB?

  2. in the VB version, strings are wrapped by a function

  
  Private Function L(data As String) As String
  L = StrConv(data, vbUnicode)
  End Function
  
  hBtn = XBtn_Create(8, 30, 100, 20, L("button"), hWindow)
  Run

  How can we represented this convertor in nim? When I use string directly, the displayed characters are not what I expected. I also tried +$(string) in winimwinstr.nim, but the displayed character is wrong too.

  3. in the VB version, an argument is the address of function

  
  Public Function OnClick(ByRef bHandle As Long) As Long
      bHandle = True
      OnClick = 0
  End Function
  
  
  XEle_RegEventC hBtn, XE_BNCLICK, AddressOf OnClick
  Run

  how can we do that in nim?

  Thanks
