I would like to assign a value in a class property dynamically (that is referring to it using a variable).
#Something like:
setPropValue($obj, $propName, $value);
Hi,
I want to send the following JSON text {"Email":"[email protected]","Password":"123456"} to a web service and read the response. I know to how to read JSON. The problem is that the above jason object must be sent in a variable name jason. How can i do this from android? Like creating a request object setting content headers etc.
I have a dictionary that is populated with data from a table, we are doing this so we can hold multiple SQL tables inside this object. This approached cannot be discussed.
The Dictionary is mapped as a , and contains SQL column name and the value, and each dictionary resembles one row entry in the Table.
Now I need to display this on a editable gridview, preferably the ASPxGridView.
I already figured out that I should use Dynamic Objects(C#), and everything worked perfectly, up to the part where I find out that the ASPxGridview is built in .NET 2.0 and not 4.0 where Dynamic objects where implemented, therefor I cannot use it...
As you cannot, to my knowledge, add rows to the gridview programmatically, I am out of ideas, and seek your help guys!
protected void Page_Load(object sender, EventArgs e)
{
UserValidationTableDataProvider uvtDataprovider = _DALFactory.getProvider<UserValidationTableDataProvider>(typeof(UserValidationTableEntry));
string[] tableNames = uvtDataprovider.TableNames;
UserValidationTableEntry[] entries = uvtDataprovider.getAllrecordsFromTable(tableNames[0]);
userValidtionTableGridView.Columns.Clear();
Dictionary<string, string> firstEntry = entries[0].Values;
foreach (KeyValuePair<string, string> kvp in firstEntry)
{
userValidtionTableGridView.Columns.Add(new GridViewDataColumn(kvp.Key));
}
var dynamicObjectList = new List<dynamic>();
foreach (UserValidationTableEntry uvt in entries)
{
//dynamic dynObject = new MyDynamicObject(uvt.Values);
dynamicObjectList.Add(new MyDynamicObject(uvt.Values));
}
}
public class MyDynamicObject : DynamicObject
{
Dictionary<string, string> properties = new Dictionary<string, string>();
public MyDynamicObject(Dictionary<string, string> dictio)
{
properties = dictio;
}
// If you try to get a value of a property
// not defined in the class, this method is called.
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
// Converting the property name to lowercase
// so that property names become case-insensitive.
string name = binder.Name.ToLower();
string RResult;
// If the property name is found in a dictionary,
// set the result parameter to the property value and return true.
// Otherwise, return false.
bool wasSuccesfull = properties.TryGetValue(name, out RResult);
result = RResult;
return wasSuccesfull;
}
// If you try to set a value of a property that is
// not defined in the class, this method is called.
public override bool TrySetMember(SetMemberBinder binder, object value)
{
// Converting the property name to lowercase
// so that property names become case-insensitive.
properties[binder.Name.ToLower()] = value.ToString();
// You can always add a value to a dictionary,
// so this method always returns true.
return true;
}
}
Now, I am almost certain that his "Dynamic object" approach, is not the one I can go with from here on.
I hope you guys can help me :)!
Please help me with writing a sql query - I have a table with id, name and marks columns.
If I arrange the table in ascending order of marks, how can I fetch 5 names whose marks are close to a particular name.
HOWEVER! would setting the $link to my database be one thing that I prolly should use a GLOBAL scope for? In my setting of (lots of functions)...it seems as though having only one variable that is on the global scope would be wise.
I am currently using the functions to transfer it back and forth so that way I do not have it on global...but it is a bit of a hinder to my script.
Please Advise,
Thank you.

Hi,
I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that:
file = open(filename, 'rb')
while 1:
byte = file.read(8)
# Do something...
So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks.
I know I can use System.DirectoryServices to roll my own GAL Name/email selector control and I've seen plenty of people explaining the basics of how to do that, but surly someone knows of one that I can download from somewhere. It just seems like a waste to have to remake it when so many people need it.
Something remotely similar to Outlooks GAL Select Names dialog. It could be simpler.
Everyone knows the names Dijkstra, Kernighan, Richie, Bloch and so on but are there actually (well-known) female programmers/computer scientists who made a great impact, developed some fundamental ideas, etc.? Shame on me, I don't know any (and probably some of you neither)...
I need to display a piece of HTML only if a variable value appears in a list. I know that Django 1.2 has an 'in' operator. But I am working on a Google App Engine app. Is there a workaround I can use?
I have two tables:
create table [dbo].[Main]
(
[ID] [int] identity(1,1) primary key not null,
[Sign] [char](1) not null
)
create table [dbo].[Names]
(
[ID_Main][int] primary key not null,
[Name][nvarchar](128) not null,
constraint [FK_Main_Users] foreign key ([ID_Main]) references [dbo].[Main]([ID]),
constraint [CK_Name] unique ([Name], [Sign])
)
The problem is with the second constraint CK_Name
Is there a way to make a constraint target column from a foreign table?
Hi,
as I probably do not describe the problem in the right terms, I was not able to get an answer with google. Please excuse!
In the following code, I would like to replace 'hardcoded' identifier COMMENT with the variable editedField. How to do that?
var editedField:String = event.dataField;
if (model.multipleProcessingData[i][editedInformationProductNO].COMMENT != null{
...
}
I got this great idea that I'm thinking about implementing, but before I go into the deep end I wanted to get a clue about what options I have.
I'm looking for an open source, programmable video player.
Must:
Play video files from a user's computer not a server
Connect to a server to retrieve/send info (not limited to file xfer)
Prefer:
Web-based player
Easily programmable (because i'm no pro at programming <;
Any names of open-source programs or players that you guys think I could use?
Any help is really appreciated
I am trying to created nested dictionary variable like the below, But I get compile error stating that it needs "}" at line where I am adding items (line #2) to my nested dictionary.
What Am I missing here? Thanks.
Dim myNestedDictionary As Dictionary(Of String, Dictionary(Of String, Integer)) = New Dictionary(Of String, Dictionary(Of String, Integer))()
myNestedDictionary.Add("A", New Dictionary("A", 4)())
Worrying about duplicates but can not seem to find and answer I can understand in any of the other posts, I just have to ask:
When I have in my .h:
@interface SecondViewController : UIViewController{
NSString *changeName;
}
@property (readwrite, retain) NSString *changeName;
then in my .m
@synthesize changeName;
-(IBAction)changeButton:(id)sender{
changeName = @"changed";
}
Is it the synthesized property or the instance variable that get changed when I press "changeButton" ?
I get the following errors:
error: missing terminating " character
and
error: stray `\' in program
In this line of C code:
system("sqlite3 -html /home/user/.rtcom-eventlogger/el.db \"SELECT service_id, event_type_id,free_text, remote_uid FROM Events WHERE remote_uid=\'%d\' ORDER BY start_time DESC;\" > lol.html", nr);
"nr" is a integer variable.
I have gone over this so many times but are totally stuck of finding a solution.
EDIT: The errors is the ouput while compiling with gcc if I didn't make that clear.
I have an object of type Hash that I want to loop over via hash.each do |key, value|. I would like to get the number of times I've been through the loop starting at 1.
Is there a method similar to each that provides this (while still providing the hash key/value data), or do I need to create another counter variable to increment within the loop?
I get this error when I run the application Incorrect syntax near 12, on debugging I found that this error is caused due to the # along with the date.
Dim backdate as datetime
backdate = DateTime.Now.AddDays(-1)
on binding the data to the grid to filter the backdate records this error is caused Incorrect syntax near 12.
myqry = " select SRNO,SUBJECT,ID where datesend =" backdate
Now i am trying to extract only the date or shall I divide the date into day , month and year with DATEPART and take into a variable or convert the date or what should i do , Please help ???
Now that ICann is allowing non-latin-character domain names, should I be concerned about e-mail validation? Currently, my sites are using php functions to ensure some alpha-numeric character set in each segment of an email address. Will these other character sets, such as Cyrillic, Arabic, and Chinese, pass validation? Are there recommended php functions to utilize for this?
I have an An Array called Names[5] and one called scores[5][5]
each row coesponds with the name in the respective index.
I need to find the highest score in the scores array and return the name that corosponds with it
Given a class like this:
class B
class << self
attr_accessor :var
end
end
Suppose I can't modify the original source code of class B. How might I go about removing the setter on the class variable var? I've tried using something like B.send("unset_method", "var="), but that doesn't work (nor does remove_method, or overwriting that method with a var= method that doesn't do anything). Any ideas?
Similiar to question:
http://stackoverflow.com/questions/2266132/how-can-i-get-a-list-of-element-names-from-an-xml-value-in-sql-server
How would I also get the values for the list of elements.
For example:
a1
b1
c1
Would return
Element | Value
A | a1
B | b1
C | c1
I would like Qt Creator to build the project according to the type I specify in the little computer button.
Using:
CONFIG(debug, debug|release)
{
DESTDIR = Debug
OBJECTS_DIR = Debug/.obj
MOC_DIR = Debug/.moc
RCC_DIR = Debug/.rcc
UI_DIR = Debug/.ui
}
CONFIG(release, debug|release)
{
DESTDIR = Release
OBJECTS_DIR = Release/.obj
MOC_DIR = Release/.moc
RCC_DIR = Release/.rcc
UI_DIR = Release/.ui
}
Or, using the answer from here, makes qmake chose the last time a variable was defined.
How do I set it?
Thnx
P.S I don't know if it has something to do with my problem, but I'm using Ubuntu and not Windows
