I'm trying to fix an issue with an application I'm supporting (I didn't write the code). The code takes an SSRS report and renders it in pdf format. Users are sporadically getting the error indicated in the title. There is no rhyme or reason to when the error is generated (a particular report will run one time and throw the error the next). The code is below.
Public Sub OpenReport()
Dim MyParms As New Generic.List(Of ReportParameter)
Dim mimeType As String = Nothing
Dim encoding As String = Nothing
Dim extension As String = Nothing
Dim deviceInfo As String = Nothing
Dim streamids() As String = Nothing
Dim warnings As Microsoft.Reporting.WebForms.Warning() = Nothing
Dim bytes() As Byte
Dim format As String = "PDF" ''#to open the report in pdf; report viewer invisible
Try
If dropReports.SelectedItem.Value = "1" Then
If Session("IsBDAP") = True Then
MyParms.Add(New ReportParameter("SCAId", dropSCA.SelectedItem.Value, False))
Else
MyParms.Add(New ReportParameter("SCAId", Server.UrlEncode(Session("SCAId")), False))
End If
MyParms.Add(New ReportParameter("ProviderId", dropProvider.SelectedItem.Value, False))
If dropVisit.Visible = True Then
MyParms.Add(New ReportParameter("VisitId", dropVisit.SelectedItem.Value, False))
End If
MyParms.Add(New ReportParameter("FY", dropContractFY.SelectedItem.Value, False))
ReportViewer1.ProcessingMode = ProcessingMode.Remote
ReportViewer1.ServerReport.ReportServerUrl = New Uri(System.Configuration.ConfigurationManager.AppSettings("ReportServerURI"))
ReportViewer1.ServerReport.ReportPath = Session("ReportsFolder") & "MReport"
ReportViewer1.ServerReport.ReportServerCredentials = New MyReportServerCredentials()
ReportViewer1.ServerReport.SetParameters(MyParms)
''#Code to convert the report to pdf
deviceInfo = "<DeviceInfo>" + "<SimplePageHeaders>True</SimplePageHeaders>" + "</DeviceInfo>"
bytes = ReportViewer1.ServerReport.Render(format, deviceInfo, mimeType, encoding, extension, streamids, warnings)
Dim size As Integer = bytes.Length
ReportViewer1.ServerReport.Refresh()
Response.Buffer = True
Response.Clear()
Response.ContentType = mimeType
Response.AddHeader("content-disposition", "attachment; filename=MReport." + extension)
Response.BinaryWrite(bytes)
ElseIf dropReports.SelectedItem.Value = "2" Then
If Session("IsBDAP") = True Then
MyParms.Add(New ReportParameter("SCAId", dropSCA.SelectedItem.Value, False))
Else
MyParms.Add(New ReportParameter("SCAId", Server.UrlEncode(Session("SCAId")), False))
End If
MyParms.Add(New ReportParameter("ProviderId", dropProvider.SelectedItem.Value, False))
If dropVisit.Visible = True Then
MyParms.Add(New ReportParameter("FollowUpVisitId", dropVisit.SelectedItem.Value, False))
End If
MyParms.Add(New ReportParameter("FY", dropContractFY.SelectedItem.Value, False))
ReportViewer1.ProcessingMode = ProcessingMode.Remote
ReportViewer1.ServerReport.ReportServerUrl = New Uri(System.Configuration.ConfigurationManager.AppSettings("ReportServerURI"))

deviceInfo = "<DeviceInfo>" + "<SimplePageHeaders>True</SimplePageHeaders>" + "</DeviceInfo>"
bytes = ReportViewer1.ServerReport.Render(format, deviceInfo, mimeType, encoding, extension, streamids, warnings)
ReportViewer1.ServerReport.Refresh()
Response.Buffer = True
Response.Clear()
Response.ContentType = mimeType
Response.AddHeader("content-disposition", "attachment; filename=FReport." + extension)
Response.BinaryWrite(bytes)
I read that the default length limit is 4MB. None of the reports by themselves are even over 350K. I'm wondering if this could be caused by a caching issue. I'm not an expert, so I need some guidance as to how best to solve the problem. I also want to understand why the issue is happening. note that only 2 reports are shown in the snippet - there are about 30+ reports in the full sub. edit - I tried the proposed solution, but it didn't help (I also tried the Fiddler route, but did not see anything glaring). I thought it might be best to clarify. The reports will run fine for a while, but the execution time gradually gets slower and slower until the application eventually displays the error.

I have written an asp upload script. It works ok for small files but anything over say 4 meg and it struggles. I keep getting the following error coming up:Maximum request length exceeded. Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.Exception Details: System.Web.HttpException: Maximum request length exceeded.So the above error comes up or it times out. Is there a way to modify the code so that it won't do this? I have included the code that I have written.

When uploading a file over 4mb I receive error: maximum request length exceeded. This is fine - I don't want users to upload files any larger. But, anyone know how to handle the error in a clean way? It appears I can't avoid it with an IF statement or Try/Catch block.

If I upload a file that is larger than the configs max request length I get a "Server Response Error: Unknown Server Error" alert popup. It asks if I want to see the response page and if I click "OK" an application error window pops up saying "Maximum request length exceeded." I found this already. [URL] I was unsuccessful at getting that to work.
I also found another SO question (I can't seem to find it now) that was similar. The difference was that the OP had asked how to redirect to an error page. I don't want to do that. The answer was to use a custom error redirect that gets setup in the web.config.
I simply want to absorb the error and do nothing, I'm using the OnClientUploadError event to handle the error via js. Basically, I just don't want this stupid popup message.
One odd thing is that I don't see the error when running the app locally, but I do see the error when I've got the app deployed out to our server. Note I should have mentioned that I know about the config value to set the max request length. Setting it to be very large won't work for this instance. Update So, I'm wondering if this could be something with the IIS settings of our server. It's odd that it doesn't happen locally. what I should be looking for? Most of what I find on the net suggests modifying the machine.config. However, as I said before, I don't simply want to up the allowed size. I am handling the error fine via js, I don't want this alert to show up under any circumstances. Update Well, it sounds like the IIS default limit is 30MB.

I am using DotNetNuke and I have posted this in their forum. But it is more appropriate here. I am trying to upload a 13 MB video file to my site ( a .flv file) using the file manager function under the host login. I understand that .NET limits the upload size to 4 MB for security reasons. In accordance with other posts here I added this code to my web.config file to allow bigger upload.
<httpRuntime maxRequestLength="51200" enable = "True"
I added it in the system.web section. Now, I still get this error:
"An error has occurred.DotNetNuke.Services.Exceptions.PageLoadException: Maximum request length exceeded. ---> System.Web.HttpException: Maximum request length exceeded. at System.Web.HttpRequest.GetEntireRawContent() at System.Web.HttpRequest.GetMultipartContent() at System.Web.HttpRequest.FillInFormCollection() at System.Web.HttpRequest.get_Form() at System.Web.HttpRequest.get_HasForm() at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull) at System.Web.UI.Page.DeterminePostBackMode() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint,

When the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?

We are using HttpRuntime.Cache API in an ASP.NET to cache data retrieved from a database.
For this particular application, our database queries feature a LOT of parameters, so our cache keys look something like this:
table=table1;param1=somevalue1;param2=somevalue2;param3=somevalue3;param4=somevalue4;param5=somevalue5;param6=somevalue6... etc...
we have so many parameters that the cache key is several hundred characters long. is there a limit to the length of these cache keys? Internally, it is using a dictionary, so theoretically the lookup time should be constant. However, I wonder if we have potential to run into some performance/memory problem.

I encounter "maximum length exceeded" error when I try to upload a document which is 9MB in size. I know that the issue will be solved if httpRuntime maxRequestLength and requestLengthDiskThreshold in web.config are increased but what I am looking for is how I can nicely handle the error and show the message to the user. I did try to use Application_Error event in global ascx but the event is not fired. The reason might be from Server.Transfer from DNN PageBase class's OnError method.
Specifications:
NET 3.5 SP1 (ASP.NET)
IIS 6
DotNetNuke 5.4.4(2)

I'm trying to bind a data table like:
month value
5 345
10 1300
12 450
to an ASP.NET Chart control. My problem is that the data table only contain months that have values while in the chart i want to show the full month range from 1st to the 12th.
So i used :
Chart1.ChartAreas["ChartArea1"].AxisX.Minimum = 1;
Chart1.ChartAreas["ChartArea1"].AxisX.Maximum = 12;
But when i do this, a part of the final series gets cut off in the middle like this.
I can avoid this issue by making the maximum 13 but that would not be appropriate since i just need to show the months of the year.

I have to set maximum length for bound field in an editable gridview. For this i have used data format string property and also given ApplyFormatInEditMode="true" still it accepts invalid input. The gridview does not have template field, it contains bound fields only. I have written OnRowEditing and RowUpdating events. The dataformat string is DataFormatString="{0:N0}" but it accepts '2352345234523454352345' input also and displays server error while updating in database. I want to spcify maximum length for the textboxes generated dynamically when Edit button is clicked.

I have a gridview, in which i placed checkbox as Itemtemplate. My need is to restrict the user from selecting more than 'N' number of selections.
Eg: Gridview contains 50 records, that means 50 check boxes.
Max permitted selections: 10.
After the 10th checkbox selection, user should be prompted that..
"No more selections.. blah blah... "
Should i go for looping through records.. or is there any better way..
