C# - Automatically Inserting New Fields In A Web.config File?
Apr 15, 2010
I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great.
But where it needs to be used, there aren't these thre fields in the web.config (this was expected, I've just added by hand for tests and developing).
How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ?

My codes below are to insert a new data into the database. The thing is, this code can insert the primary key(DeviceID) into the database automatically but I cant seem to find the code to insert the primary key into the database. point me the statement that insert primary key(DeviceID)..
This is the snippet of the submit button event
Protected Sub SubmitDevice_Button_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitDevice_Button.Click If Session("canUploadBool") = False Then ClientScript.RegisterStartupScript(Me.GetType,
"canuploadScript", "")
Exit Sub
End
Dim insertNewProcess As String = "INSERT INTO Device_Table("
Dim deviceColumn As String = "DeviceRevision, CustomerName, CustomerCode, CustomerResponsibleEngineer, Date, DevicePartNumber, PackageType"
Dim deviceValue As String = ") VALUES ('01', '" + CustNameDropDownList.SelectedValue.ToUpper + "', '" + CustCodeLabel.Text + "', '" + CustomerResponsibleEngineerTextBox.Text.Trim.ToUpper + "', '" +
Format(Now, "dd-MMM-yyyy").ToUpper + "', '" + DevicePartNumberTextBox.Text.Trim.ToUpper + "', '" + PackageTypeTextBox.Text.Trim.ToUpper + "'"

I have an SQL datasource that successfully enters customer details into a table. What it includes is the persons address. First of all we add the persons address, then we add the persons name to that address in a seperate physical procedure. i.e. on a different form.
What I need to do is try and stop users entering the same address twice. The way I have thought of doing this is by making a string field called AddressIdentity and have this contain the door number and the postcode of the address with all the spaces stripped out. Then when adding the address, it checks if this exists before adding it. However I cannot work out how to put the 2 fields together without using the codebehind file, which I don't mind doing if I need to, but I'm sure its avoidable.
Here is my code - I have only included the relevant parts:
InsertCommand="INSERT INTO [tbl_shop_client_addresses] ([FlatNo], [Address1], [Address2], [Town], [County], [Postcode],
[Country], [Telephone], [DoorNo]) VALUES (@FlatNo, @Address1, @Address2, @Town, @County, @Postcode, @Country, @Telephone, @DoorNo)"
<InsertParameters>[code]......
So how do I do it? I was trying:
InsertCommand="INSERT INTO [tbl_shop_client_addresses] ([FlatNo], [Address1], [Address2], [Town], [County], [Postcode],
[Country], [Telephone], [DoorNo], [AddressIdentity]) VALUES (@FlatNo, @Address1, @Address2, @Town, @County, @Postcode, @Country, @Telephone, @DoorNo, @Postcode + @DoorNo)"
but of course AddressIdentity is a string. Do I use ' ' marks with an & sign? Or can't I do this?? Maybe I need to use the codebehind anyway to see if the field exists before inserting it?

I would like to use a command parameter to concatonate two fields
protected void Notes0_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
e.Command.Parameters["Comments"].Value = Eval("LeadID")&" "&Eval("TextBox1");
}
Where the leadID is based on a query string and comments are entered in textbox1

I'm currently developing a software application for my client. Part of the project is to keep track of his stock's shipping status. The client must insert the stock's pick-up date, expected time of departure (ETD) and expected time of arrival (ETA). The stocks will be called out using Grid View and the status, being one of the keys of the database, will be shown. Before the current date reaches pick-up date, the status must show "in warehouse", and after the current date reaches pick-up date and is before ETD, status must show that its "on the way to the port", and after ETD and before ETA, "in freight", and finally after ETA, "arrived". What datatype should I use for the database and where should I program it so that it changes automatically accordingly ?

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'm using MVC 2 with some Models from a LinqToSql project that I built. I see that when I post back to a Controller Action after editing a form that has a DateTime field from the Model, the MVC Html.ValidationMessageFor() helper will nicely display an error beside the Date text box. This seems to happen automatically when the you test ModelState.IsValid() in the Controller Action, as if the MVC model binding automatically knows that the DateTime field cannot be empty.
My question is... I have some other string fields in these LinqToSql generated classes that are Not-Nullable (marked as Not Nullable in Sql Server which passes thourgh to the LinqToSql generated classes), so why doesn't Mr. MVC pick up on those as well and display a "Required" message in the ValidationMessageFor() placeholders I have added for those fields?
Sure, I have successfully added the MetadataType(typeof<t>) buddy classes to cover these Non-nullable string fields, but it sure does seem redundant to add all this metadata in buddy classes when the LinqToSql generated classes already contain enough info that MVC could sniff out. It MVC validation works with DateTime automatically, why not these Not-nullable fields too?

I noticed that we always just are like:
SmtpClient mSmtpClient = new SmtpClient();
// Send the mail message
mSmtpClient.Send(mMailMessage);
And the only place the credentials are set are in web.config:
<system.net>
<mailSettings>
<smtp>
<network host="xxx.xx.xxx.229" userName="xxxxxxxx" password="xxxxxxxx"/>
</smtp>
</mailSettings>
</system.net>
So my question is, how does it automagically get them out?

I have connection strings info in web.config. I thought that if this were the case, machine.config would be ignored. But, everytime the connection string in web.con is different than the connection string in maching.con, I get error. The connection name 'aspnetdbConnectionString' was not found in the applications configuration or the connection string is empty. Is there something I can check or change to get the app to ignore the machine.config when web.config connection string is listed.

A while ago when i started using VS 2005, i found that some assembly entries were automatically added to from web.config
and i was getting annoying errors. later i found i have added unneccessary references in my application. And its a feature that assembly reference are automatically added to assembly tag in Web.config, So dev don't have to worry about it.
Recently i used Interop.OWC11.dll in my application. And ^&*# got the annoying
"CS0234: The type or namespace name 'Office' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)"
error again.. Assembly entry was not added automatically. I checked same for existing references in my application, for them to automatic entries is not happening.... ? :(
I have to write is down in Web.config manually... I don't understand why?....

Currently, I work on an ASP.NET project which is hosted under version control and is used on several developer machines, tester machine and production environment.
In three cases, configuration (Web.config) may be different. For example, developer and tester environments use testing SQL Server, whereas in production environment, another SQL Server is accessed, so the connection string is different in those cases.
We want to keep three versions of Web.config in subversion. But modifying each of three files every time we need to add, remove or change a common setting is annoying: it would be nice to have a common, master Web.config, which will be inherited by each of the three Web.config files.
How to set up an ASP.NET project which will use a master configuration file and different slave configuration files on different machines, thus sharing the same project/source code/configuration files in subversion?

When I open my ASP.NET site in IIS and try to open the .NET Trust Levels, I get an error message:
.NET Trust Levels There was an error while performing this operation.
Details:
Filename: ?C:inetpubwwwrootmyappweb.config
Line number: 445
Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"),or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
I've checked a few places, but I haven't found anything that seems like it would be locking that setting. Is there a systematic way of determining where that setting is locked?
I'm using IIS 7.5 and .NET 3.5 sp1.

currently in our application we have an ApplicationConfiguration class. It is basically just a static class with const values specifying certain application-global configuration options. Some of these values will rarely if ever change and are only put into the configuration for elegance/cleanness.
Some of these values though do need to be different between production and development. So I'm considering making this class just a wrapper over Web.config. These values are checked many times throughout our codebase. If I change these from a const to a read-only getter that reads from Web.config will this affect compiler optimizations or make our application in any way slower?

It is known that we use web.config file to override the setting of machine.config file.
a) how come machine.config file knows that only changes made in web.config file are to be overwritten. I mean to say, if I use some other name for the config file say xyz.config, will it be able to work?
b) How does machine.config file know about web.config? Is there any link mentioned inside the machine.config file for that?

Thing is in past, I had deployed the SAME application using the SAME method.

I have a small web application based on asp.net 2010 that manages invoices.
After the invoice is saved, it should automatically generate a pdf file.
which of the following solutions would be fast and easy to incorporate?
Use Sql Server 2008 Reports
Use Crystal Reports 2008 and Crystal Reports 2008 for VS 2010
Use itextsharp to create the pdf file
Use XSLFO to create the pdf file
The point here is I dont know any of the above. Which one is easy and quick to learn and implement. Are there any other solution to achieve this functionality?
