View 3 RepliesAfter upgrading an asp.net application to 2.0 from 1.1 I am receiving a large 100+MB .tmp file in C:Temp on the web server when the w3wp process serving that application crashes. If you open the file it looks like it is some sort of dump file. how to turn this off. I know what is crashing the application and process.
View 2 RepliesI am trying to read a normal string from the web.config file. When I try to read a string from the web.config file the application doesnt seem to read it. I set my sqlconnection string in the web.config file. It reads a sqlconnection string but not a normal string.Here is my code:
web.config file:
<applicationSettings>
<MyApplication.Settings>
<setting name="Colour" serializeAs="String">
<value> "Red"</value>
</setting>
</MyApplication.Settings>
</applicationSettings
This is how I try to call the setting:
string strColour = Properties.Settings.Default.Colour;
I am using .net framework 4.0
I've written a aspx.net(C#) page that after the user has done what they do on the page they hit a Submit button. The Submit button
1) takes the work the users was producing on the page and writes it to a file.
2) attempts to execute a batch file.
The call to the batch file is executed via:
protected void Execute123EDI()
{
try
{
string File = @"c:80sAdminSendV80s.bat";
lblCancelled.Text = lblCancelled.Text + File;
Process proc = new System.Diagnostics.Process();
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.LoadUserProfile = false;
proc.StartInfo.UserName = "administrator";
proc.StartInfo.RedirectStandardOutput = true;
System.Security.SecureString secPass = new System.Security.SecureString();
string paswd = "123abc";
for (int i = 0; i < paswd.Length; i++)
{
secPass.AppendChar(paswd[i]);
}
proc.StartInfo.Password = secPass;
proc.StartInfo.FileName = File;
proc.Start();
FileStream fs = new FileStream(@"c:80sAdminSendV80sOutput.log", FileMode.Append);
StreamWriter sw = new StreamWriter(fs);
sw.Write(proc.StandardOutput.ReadToEnd());
proc.WaitForExit();
sw.Close();
proc.Close();
}
catch(Exception ex)
{
lblDebug.Text = lblDebug.Text + ex.Message + "<br/>";
}
If I watch the processes tab in Task Manager on the web server I see "cmd.exe" under the context of 'administrator' but it just hangs. For test purposes c:SendV80s.bat: copy c: oot.ini c:zzz.txt
If I logon onto the webserver's console and execute SendV80s.bat it works and exits without issue. But when I execute the same batch file via the Submit button it gets stuck executing in Task Manager/Process. I believe this has something to do with the fact that cmd is not running in a full environment/desktop context. I just noticed this on the actual console of the webserver (not in my RDP console but console 0 instead)
A pop-up box stating: CMD.exe Application error The application failed to initialize properly (0xc0000142). Click OK to terminate the application. And when I click on the OK button my ASPX page's WaitForExit is satisfied and the continues processing normally.

View 10 RepliesWhat is the difference between IIS Worker process, Application pool and application domain? Do we have more than one application domains in one application pool?Does one application domain means one virtual directory?
If we have 2 virtual directories pointing to same physical folder. Will they share the same memory or different when there instances are opened in the browser? Will they be in 2 different application domains?
I am trying to config my application to use out-of-process sessionState.
<sessionstate mode="stateserver" cookieless="false" timeout="20" sqlconnectionstring="data source=127.0.0.1;user id=<user id>;password=<password>" server="127.0.0.1" port="42424" />In my web.config I get errors for the server and port attributes, telling me that server attribute is not allowed and port attribute is not allowed.
So, I have a webForm that has an ImageButton. This ImageButton has to open a file (said file is uploaded by the user in another web form. The file is saved to \serverNamefiles; it can be a doc file, pdf file, excel file).
So this ImageButton should open said file as you normally would. It works on debug, however when I publish my site, and run it from my localhost, it doesn't open the file. When I click the ImageButton it just does the postback and nothing happens.
The code for the ImageButton is just:
Process.Start(fileName);
fileName has the full path of the file I want to open, in this case it has: \serverNamefilesmyFile.pdf
In my asp.net application I want to read authorization section of web.config and modify that.For that I am using the below code but I am not getting the values. So have a look at it and let me know if there is any way to read and update authorization section values
<authorization>
deny users="?"/>
authorization>
configuration = WebConfigurationManager.OpenWebConfiguration("~");
section = (AuthorizationSection)configuration.GetSection("system.web/authorization");
SectionInformation sc= section.SectionInformation;
I have an asp.net web appilcation created in .net 2.0 that is supposed to read and display the app settings from remote web.config (accessible from a shared location). Is there a better way(like reading from the application's web.config ) to read the app

I have a folder called GUI. Inside GUI thers another folder called PDF and inside this folder, there are some PDF files. This folder (GUI) is uploaded to the server too. Then I have a WebForm with some ImageButtons. When I click one of these ImageButtons, I want the file to open in a new tab. I tried with the following code:

As you can see, I build the path using the tooltips of the different ImageButtons. The ToolTip = File Name I want to open. When I try this in debug mode, it works. It opens the pdf file in a new tab.

How could you do to read a web.config file from inside a aspx file?
View 4 RepliesI'm trying to get log4net working in a 'classic' webforms app, using a log4net XML configuration file that I know is correct, as it is a copy of a file I use successfully with a number of other applications. I have the config.log4net file in the main site folder (C:inetpubwwwroot), and I configure log4net in Global.asax.cs as follows:
protected void Application_Start(Object sender, EventArgs e)
{
var log = LogManager.GetLogger("SomeWebsite");
XmlConfigurator.Configure(new FileInfo("config.log4net"));
// bind log to the DI container
...
}
Whenever I then use the log instance (even within Application_Start) nothing happens, not even an error. I know that if config.log4net is misconfigured, log4net will silently fail, but I am sure that this isn't the problem. I have a feeling it has to do with FileInfo's base path being wrong.
I'm using a .resx file which have some name and values.. I wanna read the values programatically.. the recource file is inApp_GlobalResources folder of the project..
I'm using Visual Studio 2008.. and C# as Code behind.
i have a xml configuration file like below format.
<setting>
<web>
<mailid>xxxx</mailid>
</web>
<network>
<logid>sd</logid>
</network>
</setting>
i would like to programmatically read entry from xml config file which is same as asp.net webconfig file reading.
When I hit the run button (in my Default.aspx), a process starts (this process contacts a webservice to get some files, etc). How do I: Ensure that only a single process is running at a time (i.e. if I refresh the browser, I don't want to start the process a second time)Track progress - there are 4 points of the process (at 25%, 50%, 75%, 100%) that I want to track, and when each part completes, I want to update the progress bar. I have a status object for the running process, but the question is how to update the progress bar automatically? Do I need to use threads to achieve the above two?
View 1 RepliesI'm trying to use the following command:
Dim xmlFilePath As String = _
System.Configuration.ConfigurationManager.AppSettings("XmlFilePath")
to retrieve the following setting:
<applicationSettings>
<MySolution.WebProject.My.MySettings>
<setting name="XmlFilePath" serializeAs="String">
<value>C:ASP.NETFolderMessageLog</value>
</setting>
</MySolution.WebProject.My.MySettings>
</applicationSettings>
However, xmlFilePath shows up as Nothing after that line of code is run. What's the correct code to get a setting out of the web.config file in an ASP.NET application?
NOTE: Although you can add keys individually to the <appsettings> tag, I'm trying to figure out how to use it with the "Settings" tab in the project's properties.
I have a web app where user uploads a file.ile is saved in server locally and I want to read some data from it.Currently my development server has office 2003.So do I need office 2007 in order to be able to read an excel from office 2007 ?

Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();
I've developed a popup email .aspx used on our intranet based web app that is auto generated with .pdf's attached. I'm developing with VS 2008 ASP.Net 3.5 C# and System.Net.Mail.MailMessage. I can create and send the email with no issues. The problem is with any attempt to open or delete the attachments I get the above error. The .pdf's a copied with the following code:
FileStream fsr = new FileStream(inFilename, FileMode.Open, FileAccess.Read, FileShare.Read);
BinaryReader reader = new BinaryReader(fsr);
byte[] bytes = new byte[fsr.Length];
reader.Read(bytes, 0, bytes.Length);
FileStream fsw = new FileStream(outFileName, FileMode.Create, FileAccess.Write, FileShare.Write);
BinaryWriter writer = new BinaryWriter(fsw);
writer.Write(bytes, 0, bytes.Length);
// clean up
writer.Flush();
writer.Close();
writer = null;
fsw.Close();
fsw.Dispose();
fsw = null;
reader.Close();
reader = null;
fsr.Close();
fsr.Dispose();
fsr = null;
Later after sending the email I:
mailMessage.Dispose();
mailMessage = null;
foreach (string fileName in attachments)
{
if (File.Exists(fileName))
File.Delete(fileName);
}
The error occurs at: the File.Delete(fileName);
how I can delete or reopen these files after sending the email?
I am trying to download a file from the server but i am getting this error:
The process cannot access xxxx the file because it is being used by another process
This is my CODE:
string fileName="DownLoadFiles";
string filePath = hid_filepath.Value;
FileInfo file = new FileInfo(filePath);
System.Net.WebClient wc = new System.Net.WebClient();
wc.DownloadFile(new Uri(fileName, filePath);
Foe ur Information:the file is not opened or not used.
My code is that I want to create a log file and log it upon a new user browsing the site. However, what i did was I put in a 6 second delay and then used another browser to access the page. And it threw an Exception saying it is being used by another process which is true. So how come I set it so that, if IT is being used by another process, WAIT and retry every 500 milliseconds until it becomes free/available?
here's the code:
protected void Page_Load(object sender, EventArgs e)
{if (!IsPostBack) // if this is the first time page loads, set k to 1
{ lognewuser();
}}
[Code]....
