The document can be opened when clicked on Image Button. but, the problem is taht after opening the document, I am unable to perform any other action in the grids.... Other actions like...selection in checkboxes(master grid contains few check boxes),other link buttons in detail grid....etc etc...I am getting the following errr:
PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled
This is because after opening any document,for any action again Handler is being called.

Runtime Error
Description:
An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I have an application that uploads an Excel .xls file to the file system, opens the file with an oledbconnection object using the .open() method on the object instance. The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers).
string connectionString = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";") + "Extended Properties="Excel 8.0""
OleDbConnection connection = null;
connection = new OleDbConnection(connectionString);
connection.Open();
The exception comes on production server at connection.Open() some times, when I reset the asp.net worker process it started to work but after some hours/days It occurs again. how can I fix this issue which comes in production some times but very irritating, or there is some other work around.

Even though there is a certificate error (trusting issue) it works fine with Firefox.(We can add the exception) But as shown below it does not work properly on IE (both 7 & 8) Is there any settings we can do on both client side or Server side. (I have turned off security for IE on server)

I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this?
Below the code which should make the relation to the resourcefile en specify the error when the field is left empty.

View 8 RepliesI have a web page, that has lists of documents for a user to look at. I have the page working to allow a user to view any of the documents when they click the link. The only thing that wont work is a document that is .msg format for Outlook emails. I did some research and found that in order to get Outlook to open the document when opening a .msg document, you have to add the MIMEType application/vnd.ms-outlook to the list of MIMETypes that IIS will accept. I gave this a shot but still couldn't get it working.
Then what I tried was to output the MIMEType associated with a .msg when I was Saving the document so I could see what it was using. When I did this I got "application/octet-steam" So then I set the .msg extention to use octet stream. This allowed the document to be open, but used Notepad which then had really messed up formatting because of the email headers etc.
Does anyone know how I might get outlook to open up and show the email when a user clicks to view that document as opposed to Notepad?
I would like to get validation messages for validation controls from resource files. I know I can do that easily by following code snippet.
<%$ Resources:[filename prefix,]resource-key %>
or
<asp:Label ID="Label1" runat="server" meta:resourcekey="resource-key-prefix" />
But I would also like to parameterized it.
e.g.
Above Resource Expression will give me message like "Fill Information.". What I have in resource file is "Fill {0} Information." which should show end user message like "Fill Address Information.".
I'm making changes to some xxx.resources files on our web server, everytime I try and copy the new file out to the server I keep getting the error:
'the process cannot access the file because it is being used by another process.'
I get this for about 20 minutes or so after I check the web site. Is there another way to update/copy the xxx.resources file on the web server without waiting 20 minutes or so to do so?

I've got an ASP.NET website that has abotu 10 projects makign it up which are compiled into DLLS and in the bin directory. ReportingContents is one of these projects. In the past I have had success in copying over a new version of the files (dll, pdb and xml) to the bin directory and recycled the app pool and it just picks up the new version on its own. This time I thought "I shouldn't have a debug version on the site" so I built as release and just copied up the dll and xml files and asked our deployment people to remove the pdb.When I was told it was all done I tried to access the site and got the above error message.The thing that surprises me is that the assembly it mentions is "Delete ReportingContents" and I don't know where the "Delete " might have come from in there.

All of the following have been tried over and over again:
1.) Delete all existing .dlls
2.) Delete MasterPage File and recreate it.
3.) Delete MasterPage perform a clean rebuild then recreate
4.) Delete web.config file and recreate
5.) Delete web.config file perform a clean rebuild then recreate
6.) Destroy the entire project and start from scratch
7.) Before any of these steps were taken the project was built with Ctrl+Shift+B and again with F5
8.) Checked all of the namespaces to make sure nothing was conflicting
9.) Checked IIS7 to see which .NET Framework was being used and it is all listed under 2.0 and later at one point even trying to swithc it over to .NET 4.0
The problem is rather persistant, annoying, and frustrating and I would truly love to acquire some input on correcting this matter,issue occured out of the blue one minute working the next minute it errors out.
