I'm attempting to call a stored procedure, but one of the parameters is "ref long? partyId" and I'm not sure how I'm supposed to pass or not pass something.
What should I be passing in the arguments to either bypass this or appease it?
long? means Nullable<long>. The ref means it is being passed by reference instead of by value. When you pass the value, you need to include ref before the parameter you are passing. Something like this:
long? myLong = 0;
myProcedure(ref myLong);

I have the following code:
dim key
for each key in Request.Querystring
'do something
key = sanitized_param(key)
next
My question for you classic-asp connoisseur, does classic-asp, or asp in general, pass the variables as references(memory), or by value? Trying to figure out if I sanitize the key variable and pass it back to itself, is it just "alive" for that loop, or does the new value get passed to the original QueryString?
Request.QueryString retrieves the query string parameters by value from the page headers.
You can only make changes to a query string once its been retrieved via Request.QueryString, but you can't make changes directly to Request.QueryString as it's read-only (If you could make changes you would presumably use Response.QueryString, but this isn't a valid response command).
I'm guessing you're trying to sanitize all your query strings in one go? This isn't really possible or indeed necessary. You would typically sanitize a query string as and when you request it:
Response.Write(sanitized_param(Request.QueryString("myQS")))
Or to assign the query string to a variable first then sanitize it:
Dim myQS
myQS = Request.QueryString("myQS")
myQS = sanitized_param(myQS)
' or
myQS = sanitized_param(Request.QueryString("myQS"))
Once the query string has been assigned to a variable and sanitized you're able to reference that variable as often as you like without having to pass it to your sanitize function again.
Also, your example code doesn't make much sense. The key value in your for each loop is referencing just the names of your query strings and not their values. If Response.QueryString was a valid ASP command you would do:
Response.QueryString(key) = sanitized_param(Request.QueryString(key))
But again, this isn't possible.
EDIT: This solution might be what you're looking for:
Create a dictionary object, call it "QueryString" for example. Loop through all your query strings and add a sanitized version to the dictionary object.
Dim QueryString : Set QueryString = Server.CreateObject("Scripting.Dictionary")
For Each Item In Request.QueryString
QueryString.Add Item,sanitized_param(Request.QueryString(Item))
next
Now, to retrieve a sanitized version of a query string just use:
QueryString.Item("query_string_name")
Or for the original unsanitized version you could still use:
Request.QueryString("query_string_name")
Just like Request.QueryString, the dictionary object is forgiving and won't return an error if you ask for a query string that doesn't exist.
You could also create a function for retrieving sanitized query strings, for example:
Function SanitizedQS(ByVal qsName)
SanitizedQS = sanitized_param(Request.QueryString(qsName))
End Function
And rather than using Request.QueryString("query_string_name") just use SanitizedQS("query_string_name").
I have an array of bytes in my model
public byte[] created_dt { get; set; }
It represents a timestamp value in the database.
In my view , I am referring it as #model.created_dt
but it is coming as system.byte[]
How to resolve this?
Try as this is just an example to achieve the functionality
#foreach(var a in model.created_dt){
<label>#a</label>
}
Judging by the behavior, this looks like ASP.NET and you are simply seeing the output of an implicit call to ToString() on the array (the default way of displaying anything that does not have a template defined). You will have to do something with the raw byte data and present it to the user.
Since you refer to "timestamp" and the property name might suggest a record creation time, you may want to write a helper method to translate this raw data to a DateTime which you could then format accordingly.
However, one of the following is most likely true:
It strikes me as odd that you are using raw binary to store what should otherwise be a datetime2 column. (Or it is a datetime in your database but you're doing something unorthodox to retrieve the value.)
Your property/column name of "created_dt" is a misnomer and it is really a timestamp (i.e. rowversion) column. In which case I don't think this is something a user would know what to do with, and it probably doesn't belong on the UI.
Is there an easy way to get a default value from an Erlang record definition? Suppose I have something like this:
-record(specialfield, {
raw = <<"default">> :: string()
}).
I would like to have some way to retrieve the default value of the raw field. Something like this would be very simple:
#specialfield.raw % => <<"default">>
This is not possible. I would need to instantiate a record in order to get the default value:
Afield = #specialfield{}
DefaultValue = Afeild#specialfield.raw
DefaultValue % => <<"default">>
Is there an easier way of doing this? I seems like there should be some way to retrieve the default value without having to create an instance of the record.
How about:
raw_default() -> <<"default">>.
-record(specialfield, { raw = raw_default() }).
And now you have a function with the default in it. This will be extremely fast since it is a function call to a constant value. If this is also too slow, enable inlining.
Constructing an empty record and accessing one field can be done on one line:
(#specialfield{})#specialfield.raw.
Take a look at erlang - records, search section "11.8".
There's not much special about records - they're just a tuple at runtime. So to get the field raw from the tuple of default values that is the internal representation of #specialfield{} you would use:
element(#specialfield.raw, #specialfield{}).
In this case, #specialfield.raw is the index of the value for raw in the #specialfield tuple. When you pass in specialfield that resolves to a tuple in the form {specialfield, <<"default">>}.
I want to replace some string in my url like this
request.RawUrl.ToString().Replace("sometext566666", "othertest")
but it s not working why is it so?
For example, the original url is like
/sometext4554544454.aspx
and I want it like this
/sometext.aspx
I'm guessing that this is .NET. If so, you should be aware the String.Replace() returns a new string containing the result of the replacement (as do all other methods that purport to modify a string).
So you need to assign the result to a variable or field to hold the result. In some circumstances, you might assign the result back to the same place you obtained the original string from. But you're not allowed to overwrite RawUrl (and, it would be potentially confusing for you to do so).
The statement you are using is working, but you are not assigning the result of the replace function, just executing it.
request.RawUrl.ToString().Replace("sometext566666", "othertest")
If you want to keep the result, you will need to assign it to a string.
e.g.
String result = request.RawUrl.ToString().Replace("sometext566666", "othertest");
Otherwise, you can assign it to the same RawURL but I think that is a URI so you'll need to use a new URI, something like:
request.RawUrl = new URI(request.RawUrl.ToString().Replace("sometext566666", "othertest"));
Nevertheless, I'm not sure if you can actually edit that property.
I am facing an issue while passing long value to ksoap request.As ksoap accepts only string and object parameters but i need to pass a long value to the request. Can anybody help me out in this issue.
Request.addProperty("Room No",userid);
Userid is of long type.
Try using Long instance instead of long primitive:
Request.addProperty("Room No", new Long(userid));
