Hello gurus I met a critical performance issue in calling methods/properties of Excel.Application(ActiveXObject) for creating excel files in a Curl applet.
This applet is converted from a Visual Basic(6.0) application, so the methods/properties used by the Curl applet is completely the same with the original VB application. With the VB application, creating the xls file costs about twenty seconds, while in Curl, creating the same xls file (containing the same data, the same formatted style) costs about 120 seconds. So, calling methods/properties in Curl applet used about six times long time comparing with the VB application. Attached files are copied from the project codes in VB and Curl accordingly. Note the two applications in VB and Curl are identical in the meaning of function and codes logic. Codes in attached files are called in a for loop of another method/sub. Also note that it has been proved that procs like Variant-to-Boolean, vb-var-diff are not related with this performance issue. Does anyone know any reason about this big difference ? Are there any way to accelerate my Curl applet on outputting excel files with Excel.Application ActiveXObject ? The attached files are encoded in utf-8. Thank you.
