C# - Concatenating String And A Resource Value?
Mar 14, 2011
I'm having a strange behavior in my .aspx page. I'm internationalizing some pages, but as I want to keep only entities or value object in my resource I want to have a key-value like:
(pt-br)
CITY - Cidade
STATE - Estado
But when I list the entities, I want to put the " : " at end. Like:
<asp:Label ID="LabelCity" runat="server" Text="<%$ Resources:Localizacao, CITY %>:"></asp:Label>
But, if I put the " : " after the resource in text property, the page only shows " : ".
My simple solution is put after all definition of label, but I think this too wrong:
<asp:Label ID="LabelCity" runat="server" Text="<%$ Resources:Localizacao, CITY %>"></asp:Label>:

I have created a webpage called server.aspx and the related local resource file called server.aspx.resx. In the resourcefile I defined the message "{0} is required." with the key Error.
In my .aspx page I access the string:
<asp:RequiredFieldValidator ControlToValidate="textboxName" runat="server" ErrorMessage="<%$ Resources:Error %> ID="validatorName">
Now I want to pass a value, for example the name of the textbox 'Name' to the resource string, so that the errormessage is "Name is required."
Is there any possibility to pass a value to the string?

Is there any way for me to override the values that are stored in a third party assembly in an embedded resource file?
Using Red Gate's .Net reflector, I can see there are 6 resource items, but I only want to change to of them when using it in my web application.

When developing a rather complex web application that has to be localizable, it can be quite a dawnting task to make even the smallest change like changing a name for an abstract object type.To illustrate the problem, let's assume the user can create objects through our web application called a "FooBar". The web application most probably have numerous resource strings making reference to the object type "FooBar", for example, "Click here to create a new FooBar", or "Delete all the selected FooBars".During or even after the development life cycle of the web application, the owners decide that "FooBar" is not an appropriate name, and would like it to be renamed to "Thingamajic". In the web application there are thousands of references to "FooBar". Now one has to find all and replace them.

Or any class that's not X.aspx.vb. I've imported the Globalization, Threading, Threading.Thread, and UI.Page namespaces. But it won't come up in Intellisense and it gives error lines in my code. Is there a way to access use the GetLocalResource("Y") method in other classes?

I have been led to believe that the performance benefits of using StringBuilder over normal concatenation means that you should always use stringbuilder when concatenating more than 2 strings. However when I test them this does not seem to be the case. Take these 2 methods
public void TestMethod5()
{
for (int i = 0; i < 1000; i++)
{
string t = string.Empty;
t = "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd" + "dddddddd"; ;
}
}
public void TestMethod6()
{
for (int i = 0; i < 1000; i++)
{
StringBuilder sb = new StringBuilder();
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
sb.Append("dddddddd");
string t = string.Empty;
t = sb.ToString();
}
}
TestMethod5 takes 0.03 milliseconds so complete but TestMethod6 takes 1.43 milliseconds What is going on?

I am writing an SQL query in which that I will need to perform a sub select on a table, which will usually return multiple rows. I need to be able to join together the results of a certain field from all the rows into one field to output. Is this possible, and how?
For example, if the SQL query returns
id | field
1 | test1
2 | test2
3 | test3
I need the outputted field to be "test1 test2 test3".

I have a problem where I would like to get a comma-separated list of items from a couple of tables as part of a set of results. All the searching I've done so far has produced results for dealing with one or two tables. I have four, and can't get my head around how to adapt the sql to deal with it.
I have the following layout:
*Table_Castings*
+---- CastingID {PK}
| MouldID
| SerialNo
| CastRef
| MeltCode
| Signature
|
|
| *Table_CastCertificates* *Table_Certificates*
| CertificateID {PK} ----------- CertificateID {PK}
+---- CastingID {PK} Description
FileID -----------------+
|
|
*Table_CertificateFiles* |
FileID {PK} -------------+
FullLocation
The results I would like include the following columns:
CastingID, MouldID, SerialNo, CastRef, MeltCode, [Certificates],
Where Certificates is a comma separated list of Description + " " + FullLocation records. (What I'll actually do is add http:// and other html codes to make FullLocation a hyperlink, but I can do that.)
Some SQL I've already got is this:
DECLARE @str VARCHAR(500)
SELECT @str = COALESCE(@str + ', ','') + '<a href="http://' + Table_CertificateFiles.FullLocation + '">' + Table_Certificates.Description + '</a>'
FROM Table_CastCertificates INNER JOIN
Table_Certificates ON Table_CastCertificates.CertificateID = Table_Certificates.CertificateID INNER JOIN
Table_CertificateFiles ON Table_CastCertificates.FileID = Table_CertificateFiles.FileID
WHERE (CastingID = 45)
SELECT output = @str
This actually gives all records in the for the specific casting, but I keep getting an error at the "=" in @str = COALESCE when I try joining it to another query to get each casting.

I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows:
SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo
FROM Users
WHERE (CustomerNum = @CustomerNum)
ORDER BY UserName
I then set 'UserInfo' as the text field in the dropdownlist.This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist.
Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event?

Trying to localize text in ASP.NET labels... want to add a ':' after the localized text. I could just add the ':' to the localized text in the resource file, but that seems silly... there should be an easy way to do this.
<asp:Label id="RoleTypeLabel" runat="server" Text='<%$ Resources: GS3, RoleTypeLabel %>:' AssociatedControlID="RoleTypeDropDown"></asp:Label>
(note the ':' at the end of Text='...')
Of course, this doesn't work... and neither does anything I can think of to concatenate a ':' onto the end of the localized text.

I will be setting the current thread's culture at the beginning of the request lifecycle.
Does it make sense if I create my own resource.xml to store things like strings/labels/messages that will be used in the web application?
or are their drawbacks and its better if I just use the Global resources .resx files that are 'built-in' ?

In our web application we need to keep various company's settings. For eg "DiamondProdRefIDCaption","Shippingpickup","ZipCodeCaption","DefaultCountry","AllowToEditInvoice", etcThese settings are different for various companies and are placed in web.config as key-value pair.Initially, we have tried do simplify this process by adding a company_settings table in the DB so as to allow us to add companies on the fly. However, this method makes it very difficult to add a new setting
<%$Resources:DiamondProdRefIDCaption%>

I have 2 asp.net mvc2 projects in a solution. One is normal site for visitors use and the other one is admin back-end which is going to be separated by sub-domains like [URL] and [URL] The scenario is like admin will add a new item(e.g product) with image and [URL] will use that image to display product. Both application are sharing one db. so there is no problem to get the item details that is coming from the db. but for item image that has been uploaded in admin directory([URL]- any idea how to get it from general domain [URL]to display? Also what is the best way of separating the resources like image files or even css or js files across sites and how to access them?

I am using the url rewriter described here.
On production, it works great but locally, for any links that uses url rewrite, it says:
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. review the following URL and make sure that it is spelled correctly.
