Last week I wrote a function which takes a file path and returns the base64 PNG code for that image. Since it isn’t straight-forward for everyone as to how to convert that JScript code to VBScript I decided to do just that:
Public Function convertImageToBase64(filePath) Dim inputStream Set inputStream = CreateObject("ADODB.Stream") inputStream.Open inputStream.Type = 1 ' adTypeBinary inputStream.LoadFromFile filePath Dim bytes: bytes = inputStream.Read Dim dom: Set dom = CreateObject("Microsoft.XMLDOM") Dim elem: Set elem = dom.createElement("tmp") elem.dataType = "bin.base64" elem.nodeTypedValue = bytes convertImageToBase64 = "data:image/png;base64," & Replace(elem.text, vbLf, "") End Function
Feel free to use this code in your own projects. 😎
