I would like to put a value in web.config file in my project and read it programatically from .aspx page.Under which section of web.config file should I save the value. This is not a connectionstring. It is path of a file. And I how can programmatically read the value in the code?I am using C#.
View 3 RepliesI have a website written in C# that was running fine on one server. We moved it to another server and have a couple issues. I am mainly a VB.NET coder but can do a few things in C#. This is not a project - it is a website and can open it in VS2008 no problem. This is an admin site for the whole website where the user can add customer comments, etc. When logging in, it works fine. I can go to one of the admin pages after logging in and works. If I go to two other different pages, I get this error:
Object reference not set to an instance of an object.
[Code]....
It turns out this is in the main.master page and it is used by the other pages that load fine. The ApplicationTitle variable is set right in the web.config file and like I said, it shows on the other pages.
My question is why would this code work fine for some pages and not two others? All of these admin pages are under a folder called Admin and the web.config file is in the root folder of the website. Its almost like these two pages cannot see the web.config file in the root folder? Why would that be if thats the case?
Btw, when I have this loaded in VS2008 and try to do a Build, it says:
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
I would assume the folders on the server are set right since all but two .aspx pages run fine. Just something I thought I would mention. This does not really seem to be a coding issue but something not set right especially since it ran on the other server just fine.
My asp.net app has is using a web.config for common configuration. I also have a section that maps some data objects to connection strings, and that section is going to be couple thousand of lines. I want to move that section to another config file "dataMappings.config", so I don't bulk up web.config - is there a standard mechanism of accessing that config file?
View 1 RepliesI a custom config file which I am having problems reading from a class project, is there a simple way to do this? the path does not seem to be getting picked up in code, where as this works in a web project
View 2 RepliesI have code that reads a value from a config file (not web.config) given a key. It looks like this:
Code:
Public Shared Function GetCustomConfig(ByVal ValuetoGet As String, ByVal ConfigFileValue As String) As String
Dim Returnvalue As String = String.Empty
LoadConfig(ConfigFileValue)
For Each KeyValue As String In AppSettings.Keys
If KeyValue = ValuetoGet Then
Returnvalue = AppSettings.Item(KeyValue).ToString
End If
Next
Return Returnvalue
End Function
So if my config file which is named my.config has this entry: <add key="TempArea" value="c:Temp"/>I would call GetCustomerConfig("TempArea", "my.config") and the function would return "c:Temp". Most of the time this is what happens. But sometimes I get an exception: Collection was modified after the enumerator was instantiated.
Is there a better way to get the value given the key? This is code written long ago by my predecessor, and I am not sure I want to use it anymore. If I do use it, I will have to do something so that it is more reliable.
how to read the data's in the text file using sql server 2000 and 2008. i have a text file in a server and it contains one column name with the multiple column values i need to read that informations and i need to update in a table in the database.
View 2 RepliesI'm trying to read the contents of a text file into a text box on my form. When I run the following code, nothing happens.
VB.NET Code:
Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object,
ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged   Â
For Each li As ListItem In lbLogs.Items     Â
If li.Selected Then        Using sw As New StreamReader(li.Value)         Â
txtLog.Text = sw.ReadToEnd           sw.Close()        End Using      End If    Next  End Sub
I populate the ListBox with ListItems and each ListItem's Value property holds the full path to the file. But, I removed all of that and just put txtLog.Text = "test" inside of the "is selected" block.
I would like to use both of the connection strings in the same web.config file how can I do this I tried this yesterday it worked I called it a night, then this morning I got this. The error being on line: 10 Parser Error Message: The entry 'ApplicationServices' has already been added.
Line 8: <add name="ApplicationServices"
Line 9: connectionString="Data Source=Mysource;Initial Catalog=travelatlantic;User ID=MyID; Password=MyPassword;" />
Line 10: <add name="ApplicationServices"
Line 11: connectionString="Data Source=MySource;Initial Catalog=travelatlantic2;User ID=Myid; Password=MyPassword;" />
Line 12: </connectionStrings>
I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?

View 6 RepliesThe below is the custom config files
<Test>
<testA att1="A" att2="B" att3="C"/>
<testB att1="A" att2="B" att3="C"/>
</Test>
If I send testA then the class will return all testA attributes i.e att1, att2 and att3 values.
testA, testB will vary.. that means in future we will add another two tags i.e testC, testD and so on.
My application will be returned all the attributes based on my inout (testA...).
Say I have 3 keys:
<add key="w1" value="1"/>
<add key="w2" value="2"/>
<add key="w3" value="2"/>
I want to create a randomizer so that it gets random values each time.
Is there a reason why i get different result when reading collections using WebConfigurationManager.GetSection method.
It sometimes returns values correctly in the Hashtable and at other times returns nothing for the same data. Its inconsistent.
client:-
Hashtable hsh = (Hashtable)WebConfigurationManager.GetSection("test1");
Config:-
<section
name="test1"
type="System.Configuration.DictionarySectionHandler"
/>
<section
name="test2"
type="System.Configuration.DictionarySectionHandler"
/>.......
Is there a way write code in web.config file using preprocessed function. Say I created environment variables like %Temp%, %WINDIR%. order to read these I can use the configurationManager class. But I dont want to use it. I woudl like to use a preprocessed function similar to timeStampPattern="{timestamp(local)}". Here timestamp(local) retrieves the value directly. So in a similar way can i read the environment variables %temp% and %windir% using preprocessed function if any exists?

I'm preparing to deploy a ASP.NET web application. The target server has already a previous version of my web application with parameters specified on the web.config file.
In the new version of this web application, the web.config file contains new sections I would like they appear into the target web.config file on the server.
However I can't find the way to merge the new web.config sections into the existing web.config file ?
Does I have to do it programmatically, or is there a tool to merge the both files during installation ? (I'm using Web Setup Project).
I would like ask you for some ideas how can I write mechanism that will be automatically read files from folder. I don't know how to schedule the write task. I want to check for new file everyday and if the new file is in the folder read it.
View 2 RepliesI did a couple google searches about this and am not finding anything, so I thought I'd ask here. I'm working on our internal CMS and I noticed that we're getting live data back when doing debugging because of our web services instead of the dev data that I wanted. It doesn't do this on our dev CMS website, but we're trying to do all our development on localhost. Is there any way to set up an environment variable in our web config for the URL so that the CMS points to the dev database instead of live database that is referenced in the wsdl files?

One of my NUnit tests has to read in some values from config files. In my main application this process works perfectly well, however when I run the unit test, the code that reads in the values from the config files doesnt read anything in. Ive tried putting app.config in my unit test project (I even tried web.config) but nothing seems to work. Are there any special steps involved when reading from config files in an nunit test ?
View 1 RepliesI have some inherited code which stores SMTP server, username, password in the system.net/mailSettings/smtp section of the Web.config.
It used to read them like so:
Configuration c = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
MailSettingsSectionGroup settings = (MailSettingsSectionGroup)c.GetSectionGroup("system.net/mailSettings");
return settings.Smtp.Network.Host;
But this was failing when I had to deploy to a medium trust environment. So following the answer from this question, I rewrote it to use GetSection() like so:
SmtpSection settings = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp"); return settings.Network.Host;
But it's still giving me a SecurityException on Medium trust, with the following message:
