Converting String to List

I want to convet the String to a List. But I get an error can not cast String to List.
Help???
String str = "Y";
List myList = (List) str;Thanks.

1. Have your String initialized
2. Have your list object
3. Add your string in to the list (LinkedList in this
eg's case)... Easy Pizy!
String str = "a";
LinkedList myList = new LinkedList();
myList.add(str);
So if you want to pass 'str' as a list. Just
use myList. (myList is a list verion of String
'str').
Well, this doesn't change your String into a List, but it creates a List and inserts the String as the first entry there. BIG difference!
Maybe you tell us what you are trying to do, and we tell you how to achieve it.

Converting string to list -- Unknown Operator error

Dear fellow users,
in my Authorware project I'm using the following code. On my PC this works FINE, but on any other PC with the same version of Authorware this code results in EvalStatus 4/EvalMessage "Unknown Operator or Illegal character".
Summary of the code:
File := ReadExtFile("Test2.txt")
ClipSections := List(GetLine(File, 1))
An example of a line in Test2.txt is:
["C", "L", "C", "L", "C"]
The variable File contains: "[\"C\", \"L\", \"C\", \"L\", \"C\"]"
And the variable ClipSections contains: 0
I hope someone can help me figure this problem out; I've been trying to solve it (and searching online for relevant help) for hours now!
Thank you,
Caspar

Dear Michael,
I didn't realize the List Separator was dependent on the language settings. This is indeed the cause of the problem.
When using the List function, can I specify which separator to use?
Otherwise I will use something like,
if ListSeparator <> "," then replace(File, ",", ListSeparator)

Converting Arrays to List

Hi,
I have the following function that converts String[] to List of int and it's working
private String putSelect(){
        String msg = SUCCESS;
        try{
            if (session.get("selectCat") != null){
                String[] aux = (String[])session.get("selectCat");
                List aux2 = new ArrayList();
                for (int i=0;i<aux.length;i++){
                  aux2.add(Integer.parseInt(""+aux));
setSelectCat(aux2);
}catch (Exception e) {
msg = ERROR;
System.out.println(e.getMessage());
return msg;
but I know that is possible to convert from array to list using :
Array.asList
but I need that the resulting list be of int not String, is there a way to modify this setSelectCat(Arrays.asList((String[])session.get("selectCat"))); in order for that to be possible?
thanks, V

if you're using java 1.5, then a better loop might be:
for (String num : aux) {
   aux2.add(Integer.parseInt(num));
}The variable aux is already a String, so doing "" + aux is pointless. I don't know if a compiler would clean that up for you or not. I'm told that a 'for / in' loop as coded above is marginally faster than an incrementor loop.
Enjoy!

Calling a Web Service in a SSRS Report - Error Converting String to Generic List of Strings

Hello,
I am using SSRS version 2005 and am trying to call a web service to retrieve data for a SSRS report. I've looked on Google and MSDN for the past 2 days and have exhausted all options. Here are the details...
The web service method I am calling accepts 4 parameters...
Parameter 1 = Generic list of strings
Parameter 2 = DateTime
Parameter 3 = Int
Parameter 4 = Int
I have created a function (on the CODE tab in report properties) in my report that gets passed a comma delimited string and returns a Generic List of Strings that I use to format Parameter 1. The code for the function is as follows:
Public Function GetIDs(ByVal IDList as String) As List(Of String)
   Dim stringArray() = IDList.Split(",")
   Dim genericList As New List(Of String)(stringArray)
   Return genericList
End Function
I am passing a string to the function that looks something like this:
"1,2,3,4"
When I try to PREVIEW the report, I get an error that reads:
"There is an error on line 0 of custom code: [BC30002] Type 'List' is not defined"
I've tried changing the function declaration to pass back a string array:
Public Function GetIDs(ByVal IDList as String) As String()
    Return IDList.Split(","c)
End Function
This returned the error (from the web service):
"Error in line 5 position 22. Expecting state 'Element'.. Encountered 'Text' with name ", namespace"
I have also tried changing the function declaration to pass back an array:
Public Function GetIDs(ByVal IDList as String) As ARRAY
This also produced the error:
"Error in line 5 position 22. Expecting state 'Element'.. Encountered 'Text' with name ", namespace"
I know that this particular web service method DOES work because it is coded to accept nulls in the first parameter. So... when I call the method with nulls, it returns a recordset of ALL data (this works fine). Only when I pass a string to the function (which "filters" the recordset by the ID list), does the error occur.
Is SRSS limited with respect to VB.NET code so that the List(Of String) statement is not recognized? Has anyone done this before and if so, how did you convert a comma delimited string to a Generic List of Strings within a function in the SSRS report?
Any info would be greatly appreciated.
Thanks!
Bob

Hi Bob,
By default, in custom code, in order to use a variable or function that is not in the "System" namespace, we need to provide the full name.
In this case, the full name of the "List" is "System.Collections.Generic.List"
So, to solve the issue, please use the following code:
Public Function GetIDs(ByVal IDList as String) As System.Collections.Generic.List(Of String)
Dim stringArray() = IDList.Split(",")
Dim genericList As New System.Collections.Generic.List(Of String)(stringArray)
Return genericList
End Function
If you have any more questions, please feel free to ask.
Thanks,

Converting enumerations to lists with generics

hello...
i want to list off system properties and sort them.
how can you convert enumerations to lists with generics?
i tried the following in eclipse, but it fails...
     Properties properties = System.getProperties( ) ;
     Enumeration<?> enumeration = properties.propertyNames( ) ;
     ArrayList<String> arrayListEnum = Collections.list( enumeration ) ;
     Collections.sort( arrayListEnum ) ;

Because the type parameter of Enumeration (<?>) is not compatible with the type parameter of ArrayList (<String>).
You'll have to do some manual casting yourself.
Unfortunately, there's nothing to guarantee that system property keys or values are strings (hence why Enumeration<?> and no Enumeration<String>) so you'll need to cope if you find one that isn't.

Unable to convert string into binary

Hello,
I have a web application that does the following:
1. Takes in user information via form. This includes images.
2. Displays all the user information in a portfolio. Looks like the portfolio on this page:
http://wrapbootstrap.com/preview/WB00PN23G
3. When clicking on each item you are brought to a page that displays the form information and the images.
So far it works fine but instead of sending the images as binary to SQL database I send them as strings and the problem is now when I update the code on my cloud host the images no longer display but all the text displays fine. I am thinking the problem
is that instead of sending my images as strings I need to store them as binary and retrieve them as well. The problem is I did some research and have been unsuccessful in the ways mentioned.
Here is my code for the form:
//gather all the information from the form
//I call a stored procedure to send my data to my sql database
using (SqlCommand cmd = new SqlCommand("SaveImage", connection.con))
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@username", SqlDbType.VarChar).Value = UserName.Text;

cmd.Parameters.Add("@description", SqlDbType.NVarChar).Value = Description.Text;
cmd.Parameters.Add("@img1", SqlDbType.VarBinary).Value = img1;
cmd.Parameters.Add("@img2", SqlDbType.VarChar).Value = img2;
cmd.Parameters.Add("@img3", SqlDbType.VarChar).Value = ppt;
cmd.ExecuteNonQuery();
cmd.Parameters.Clear();
connection.con.Close();

Hi compuluv,
To store it in the Image object. This image object must be converted to a byte array.
Based upon your code as below, please try to change Varchar to byte[].
cmd.Parameters.Add("@img1", SqlDbType.VarBinary).Value = img1;
cmd.Parameters.Add("@img2", SqlDbType.VarChar).Value = img2;
cmd.Parameters.Add("@img3", SqlDbType.VarChar).Value = ppt;
cmd.ExecuteNonQuery();
For more detailed information, please check
C# Save and Load Image from Database
By the way, since your project is a web application, I also found a asp.net version as below.
You can get some hints.

Not able to convert string attribute to number and date please help me out

not able to convert string attribute to number and date attribute. While using string to date conversion it shows result as failure.As I am reading from a text file. please help me out

Hi,
You need to provide an example value that's failing and the date formats in the reference data you're using. It's more than likely you don't have the correct format in your ref data.

Convert String to Date and Format the Date Expression in SSRS

Hi,
I have a parameter used to select a month and year string that looks like:    jun-2013
I can convert it to a date, but what I want to do is, when a user selects a particular month-year  (let's say "jun-2013")
I populate one text box with the date the user selected , and (the challenge Im having is) I want to populate a text box next to the first text box with the month-year 2 months ahead.    So if the user selects
jun-2013   textbox A will show jun-2013
and textbox B will show aug-2013..
I have tried:
=Format(Format(CDate(Parameters!month.Value ),
"MM-YYYY" )+ 2 )   -- But this gives an error
This returns the month in number format   like "8"    for august...
=Format(Format(CDate(Parameters!month.Value ),
"MM" )+ 2 )
What is the proper syntax to give me the result    in this format = "aug-2013" ???
Thanks in advance.

You can convert a string that represents a date to a date object using the util.scand JavaScript method, and then format a date object to a string representation using the util.printd method. For more information, see:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1254.html
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.1251.html
In your case, the code would be something like:
var sDate = "2013-01-10";
// Convert string to date
var oDate = util.scand("yyyy-mm-dd", sDate);
// Convert date to new string
var sDate2 = util.printd("mm/dd/yyyy", oDate);
// Set a field value
getField("date2").value = sDate2;
The exact code you'd use depends on where you place the script and where you're getting the original date string, but this should get you started.

Convert String variable value to an Object referece type

Hi all,
I want to know that if there any possible way to convert String variable value to a Object reference type in java. I'll explain by example if this is not clear.
Let's think that there is a string variable name like,
String name="HelloWorld";
and there is a class name same to the variable value.
class HelloWorld
I am passing this string variable value to a method which is going to make a object of helloworld;
new convertobj().convert("HelloWorld");
class convertobj{
public void convert(String name){
// in hert it is going to create the object of HelloWorld;
// HelloWorld hello=new HelloWorld(); just like this.
now i want to do this from the name variable value.( name na=new name()) like wise.
please let me know if there any possible way to do that.
I am just passing the name of class by string variable then i wanted to make a instance of the class which come through the variable value.
thanx.

Either cast the object to a HelloWorld or use the reflection API (Google it) - with the reflection API you can discover what methods are available.
Note: if you are planning to pass in various string arguments and instantiate a class which you expect to have a certain method... you should define an interface and have all of your classes that you will call in this way implement the interface (that way you're sure the class has a method of that name). You can then just cast the object to the interface type and call the method.
