ExportPicture issue with OWC10

[lily]

Hi there,

I use the below codes to build a few Charts on the fly, it works on my XP
mechine but only export the last two charts on the 2K Server. Any ideas?

Private Sub ExportImage(ByVal oChartSpace As OWC10.ChartSpace, ByVal img As
System.Web.UI.WebControls.Image)

Dim strFullPathAndName As String

Dim FileName As String

FileName = "tmp\" + System.DateTime.Now.Ticks.ToString() + ".gif"

strFullPathAndName = Server.MapPath(FileName)

oChartSpace.ExportPicture(strFullPathAndName, "gif", 600, 400)

img.ImageUrl = FileName

img.Visible = True

' Thread.CurrentThread.Sleep(100)

End Sub

Are you sure the generated FileName variable is unique
for each chart? If not then your new chart will always
clobber the previous chart.

Use this for unique names
FileName = "tmp\" +
System.Text.RegularExpressions.Regex.Replace(DateTime.Now.ToString(),"\\D","
") + ".gif"

After I changed the file from .gif to .jpg, all charts display correctly.
Don't know why.
