I need to pull data out for a chart and the following is what I have come up with. While it works I know there must be a more elegant way to get the same data in the same format.

Trying to print an ASP.NET Charting control behind the scenes in my web app. I think it is a permissions issue with the printer as everything is ok up until the point where my code calls:
chart.Printing.Print(false);
bool finished = false;
while (!finished)
{
finished = File.Exists(settings.GetValue("statusfile")); // file which indicates document was printed
System.Threading.Thread.Sleep(1000);
}
At this point the page just freezes (or continues to load endlessly - infinite loop!) Understandably this is happening because I am 100% relying on the document being printed. I do intend to add a timeout, however, at the moment I am just trying to figure out why exactly the document is never being set to the printer!
I have given the account (which the AppPool is running under) permissions to all the relevant folders and even the pdf printer itself...Still nothing.
Am I missing something? Is there any issues with printing on the server side via ASP.NET? I have encountered some issues doing this via WindowsServices in the past not sure if it is a similar problem with ASP.NET websites.
Update
I updated the AppPool to give myself (admin) permissions and it is the same issue. So by the looks of things the job is never being sent to the printer. I can't seem to figure out why though...
Probably should have mentioned this in my original post....but I am invoking the printer through a referenced DLL, this code is not being called directly from my application (incase it matters). Also this runs fine on my Development machine which is running Windows 7 IIS7.0 where as the server is running Windows 2003 server with IIS6.0.
Update 2
I removed the while loop and just left in the chart.Printing.Print(false) line and turns out the document IS being sent to the printer. So the issue must be with the settings file not getting written which is why the loop never breaks out!
I need to retrieve data from a stored procedure, but not from a reader. I need to insert and read to see if there is an error code returned so I can Display It
[Code]....
This inserts data into a stored procedure, since I have a promotion going on, I want to check to see if anyone has tried to create several accounts to try to be Customer #100 or so on, I have achieved this in the procedure, and set RETURN @ErrorCode = 1
Have I Set up the SqlParameter Correctly, or do I now have to declare a direction for each parameter?
I have had problems reading from Stored Procedures and Tutorials Seam Straightforward, but thay are about readers only not Input Output

Is this possible? To display a value in a legend. Here is my code:
[Code]....
As you see above , we have more data in pie chart to plot and hence 3 DOTS appear at right bottom. Hence user cant see all the legends.Is it possible to have.say a tooltip on 3 DOTS so that when an user hovers,he sees entire / remaining legend list?
View 5 RepliesI am designing a forums website. I have prepared two tables - topic and post
topic - topicid (pk),sub, message (content), replies (count of replies), catid(fk), createdby, createddate, updatedby, updatedon, viewers( count of views)
post - postid(pk), topicid(fk), post (content), createdby, createddate, updatedby, updatedon.
retrieving data from both tables in posts page where the 1st post is in the topic table and rest i.e. replies are in the post table.
Any body worked with MS Charting control for VS 2008.
I am using the chart control to displaying marks secured by students in different exams.
Series of the chart can be dynamically generated.
I am looking for a charting tool to generate charts in my ASP.Net page which will allow me to customize the charts to a great extent like changing the background of chart, specfying custom x and y axis and much more.Moreover, another major requirement is that the chart should be interactive enough. I would like to select data points on my chart, select a range of data points on charts by making a selction with mouse clicks and use these selections for further processing.
View 2 RepliesI am plotting a chart using charting control. The x-values are text values and y values are date values.
If there is same text multiple times, then the plotted chart has multiple bars of same value. I want the values for the same text to be on the same bar.
I am making a chart on a asp.net page (visual studio 2010). I am "summing" time. As long as the sum is not more than 24hours, all goes well. But if the sum is bigger than 24hours, then I get a "Not a legal Oleaut date" error.
This is my code (simplified) :
Chart1.DataBindCrossTable(_dataset._table.AsEnumerable(), "factor",
"week",
"time",
"");
Chart1.Series[0].YValueType =
ChartValueType.Time;
duurhhmm is a DateTime field. "factor" and "week" are my groupings for the x-axis.
first question : what to do about the "not a legal oleaut date" ?
second question : on the axis I see 00:00,06:00, 12:00,18:00 and then again 00:00,06:00, etc... But I would like to have 24:00, 30:00.
I'm having a question about retrieving data. I'm using VS 2008 and I have to create a new consultation record for a patient and I've already created a database with 3 tables, which are doctor, patient and consultation.
I have 10 records saved in consultation table, and I've made a aspx form which contains a DetailsView that ask for new consultation details to be added. But I have to be able to get the doctor and patient information from the database and put in the DetailsView, then fill in the rest of the consultation details. The information entered have to be written to the database in the consultation table. But I don't know how to get doctor and patient information from database and apply them into the DetailsView so that doctor who wants to add new consultation details can select patient and doctor information from the database.
I was thinking maybe I need to do a query with insert statement and apply into the DetailView,this is the query i have:
INSERT INTO [Consultation] ([ConsultationID], [GPname], [PatientFirstName], [PatientLastName], [Height], [Weight], [IllnessDescription], [Diagnosis], [Date]) VALUES (@ConsultationID, @GPname, @PatientFirstName, @PatientLastName, @Height, @Weight, @IllnessDescription,
@Diagnosis, @Date)
as you can see, I need to get the GPname, PatientFirstName and PatientLastName from the database tables and the rest will be filled in by the doctor.
I'm getting a warning in my page directives saying that this namespaceystem.Web.UI.DataVisualization.Charting isn't found. I went to add a reference to the project so I could import the namespace and this namespace does not exist in the .NET tab. What do I need to do to get this working? Also, even if I add this to my Global Assembly Cache, that won't do anything for the web host web server that my website is publically on.Any guidance on this? How to get it on my local machine as well as understanding that it'll work on the actual web server?
View 5 RepliesI 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.

View 7 RepliesI am designing an prototyping an app the needs to store images, similar to facebook. This will be a public facing site and I am not sure how many users I will end up with but what I am looking for is a way to efficiently retrieve them.
So far I am thinking of storing them in SQL Server varbinary columns. I have the upload code and the storage code for that. My concern is retrieving them. I can retireve and build the image tag on the fly but I am worried about having to hit the database for each one.
I have been thinking about getting all images for a user and caching them in the asp.net cache for 10 to 30 seconds. I have never had to do something like this so I would be interested in hearing a few different approaches. Obviously the images can vary in size and I was thinking about defining a size limit, but I haven't gotten that far yet.
i saved files into database. when i'm displaying i wrote code like this
Dim mySqlDataReader As System.Data.SqlClient.SqlDataReader
Dim mySqlCommand As New System.Data.SqlClient.SqlCommand("pl_Resumes", mySqlConnection)
mySqlCommand.CommandType = CommandType.StoredProcedure
