<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:TempImageFiles;" />
is fine for development, but not so good for deploying on IIS. I found a forum post that mentioned you could drop the path altogether, which dumps the temp file(s) directly in the root of my project
I am seeing temp files created in my wesite directory. The files are attributed to a page that I load from a txt file for more info. I beleive when I user clicks on the more info link and I read the textfile into the page it creates the temp file named somthing like this moreinfo.aspx~RF1630b1e.TMP does anyone know a way to clean these up other than a manual task? below is the code I use to read in the txt file
<script language="vb" runat="server">
Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
Dim strURLNAme As String
Dim MyFileName As String
strURLNAme = Request.QueryString("AdultInfo")
' Response.Write(strURLNAme)
If strURLNAme = "adult" Then
MyFileName = "AdultMoreInfo.txt"
ElseIf strURLNAme = "kids" Then
MyFileName = "KidsMoreInfo.txt"
End If
'Open a file for reading
Dim FILENAME As String = Server.MapPath(MyFileName)
'read the file
Dim objStreamReader As StreamReader
objStreamReader = File.OpenText(FILENAME)
'read the entire file into a string
Dim contents As String = objStreamReader.ReadToEnd()
Me.lblNicerOutput.Attributes.CssStyle.Add("text-align", "Left")
'We may wish to replace carraige returns with <br>s
lblNicerOutput.Text = contents '.Replace(vbCrLf, "<br>")
objStreamReader.Close()
End Sub
</script>

View 10 RepliesI had a page to update user picture and redirect user to login page, the problem is when a user re-login, the old picture is still available until user refresh the page.
notes: I have already use <%@ output> but not working with master page and also have used Response.Cache.SetCacheability(HttpCacheability.NoCache) and also not working
here is my code:
Protected Sub btnUpdate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnUpdate.Click
'Updating User Pic
fuUserPic.PostedFile.SaveAs(Server.MapPath("~ImagesUserPic" & UserID & ".jpg"))
Response.Cache.SetCacheability(HttpCacheability.NoCache)
FormsAuthentication.SignOut()
FormsAuthentication.RedirectToLoginPage("msg=Please login again")
End Sub
what can I do to delete temp internet files to display picture after updating?
I have static content like html,css javascript stored in DB. when a user requests for these i create a temp file in virtual directory and return the url. My web app is hosted on a IIS server. On some systems on creation of a file my IIS Application pool crashes and restarts. If i disable file-monitoring though the problem is resolved, but i dont have this luxury when i am deplying at the client end. Is there any way by which i can avoid app pool crash during file creation? If not is there any way by which i can serve static content like html, css, images, xml and js without creating temp files. I would need a generalized way of handling all these data types.

How does one go about removing the data labels from a pie chart with the new chart control in .net 4?
I can get these to display as tooltips absolutely fine, but ultiamtely I'd like the labels not to be present as it looks rather busy.
I've searched previous answers and seen code behind resolutions but surely there must be some sort of code infront option to turn these labels off?
I am using MS Chart control (3.5), and have a requirement where I need to display 2 pie charts. The datapoints for the pie charts is set programatically. My doubts are as follows:
1. Can I display both the pie charts in a single chart control and area, or do I have to use two controls? (Currently I am using two controls)
2. How can I maintain the same size for both the pie charts? This is my main concern, since the pie sizes keep changing, depending on the number of datapoints. I tried using custom properties like "MinimumRelativePieSize", but it's not working.
i'm trying to create a stacked bar chart on a vb web form using vs2010.My data source returns:
Error in Functionality Awaiting on Supplier

IMT Issues,Awaiting on Supplier

IMT Issues Closed 120
Login / Password Active
But I can't get this into a stacked chart. I know I must have to do quite a bit of work declaring what the series are and soforth, or having a different dataset but can't find any documentation on it.A link to some documentation or an example of a stacked chart from an sql datasource would be much appreciated.
I started using the awesome chart controls with my asp.net apps recently and so far they've been nothing short of breath taking. Right now I have a weird problem, on the first load of my page, the chart control appears correctly and the tooltip is correct, however, when I update it with new data, the chart displays correctly, but the tooltips are for the previous set of data.
I hope this makes sense. The first time I load the chart, the pie chart segments and tooltips are correct, after a partial postback (to get the new data), the pie chart segments are correct but the tooltips are for the previous data set.
Basically once the tooltips are set the first time, they can't be updated after that without a full page postback.
Here's how I set the tooltip:
[Code]....
Anyone else noticed this behaviour and have a work around?
Currently my only workaround is to check for a partial postback and not render the tooltip, which I'd rather not do as the tooltip display actual statistical data as opposed to the pie itself (which uses percentages).
I have X and Y data columns coming from database.
I have to show scatter plot chart with Linear, Exponential, Log, power using asp.net chart control.
How to do that?
I'm trying to create a .net charting control completely in the code behind and insert that chart at a specific location on the web page.

im trying to create simple pie chart using the MS Chart controls. When my pie chart gets rendered in the browser i get padding around the pie chart that i cant get rid of. i would like the pie chart to sit up against the edge of the image with no padding or margin. in my code below the padding is highlighted in blue. i.e Chart1.BackColor = System.Drawing.Color.Blue;
<script type="text/C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
//Set the chart type
Chart1.Series["Series1"].ChartType = SeriesChartType.Pie;
//add points
Chart1.Series["Series1"].Points.AddY(12);
Chart1.Series["Series1"].Points.AddY(45);
Chart1.Series["Series1"].Points.AddY(67);
//set back color of chart object
Chart1.BackColor = System.Drawing.Color.Blue;
//set back color of chart area
Chart1.ChartAreas["ChartArea1"].BackColor = System.Drawing.Color.Green;
}

How can I display BrandA for XValueMember & Salesvalue(10000) for YValueMembers as Series1 having a column chart type.
And to display BrandY & BrandZ for XValueMember ; Salesvalue for YValueMembers as Series2 having a line chart type.

Or is it possible to set more than one data source for the chart control?

I'm using Microsoft Chart control in my ASP 3.5 application and since it's local it works well. After uploading it to my remote host, I received an error message regarding unauthorized access to somewhere on the server. So I changed the Image StorageMode to UseImageLocation. Now it works well, except that by each page browse, it produces a couple of images which I cannot get rid of. I found a deleteAfterServicing property set in the ChartImageHandler key defined in web.config and I set it to true, but it didn't help. What could I do to delete the temporary files and avoid bloating?
