Hi, l have an application that will generate PowerPoint and create some chart within the PowerPoint.
i've been using Interop.Powerpoint.Slide.Shapes.AddChart() to create chart in PowerPoint. The momment this function is called, an Excel window will pop out for us to fill in the data. Is there any way to tell Excel window open in minimize mode/behind other application instead of popping out and became the active window? Even if I do Chart.ChartData.Workbook.Application.Visible = false, Excel window still shows up a little while. Some of the device the Excel window will automatically open behind other application but some don't.
