Jquery - Sending A Complex Object As Parameter To Asp.Net PageMethod
Feb 22, 2010
I am trying to send an object created in JavaScript to an ASP.NET PageMethod. This object mirrors the properties of an existing custom business object, so i was hoping that i could pass a single object instead of a parameter for each property. I am getting an error "Unknown web method SavePart when attempting to use this method.
Javascript:
function() {
var pt = { Id: 1, Onhand: 20, LowPoint: 30, __type: 'Custom.Objects.Part'};
$.ajax({

I used the tool about 3 years ago to create the classes for a webservice client to send or recieve arrays as complex data. Now i have to update these classes, since there are additional informations, that have to be exchanged. When i use the tool now with the new wsdl-files, it does'nt create the classes for complex data (structur, IGCTMObjectFactory), but only one class for simple data. In addition i have to establish a new client, that sends an array of complex data and receives another array of complex data. I tried to build the classes manually combining the client that sends an array with the client, that receives an array, but I failed.

I have this function in JQuery:
[code]...
And it is supposed to read multiple lines from LimFile and send it to a string in VB.NET.Problem is that when I debug it, I see the string is there in full length. And when I split it with vbNewLine, it shows that theres only 1 line, aka nothing is split, like the newlines have been lost.

I'm trying to save some settings in a complex object. If I make a dll of the class I can then add it in the projects properties settings list as that type.When the program runs though it won't show up as anything other than nothing. I read you have to have a sub new empty constructor which I have but don't know why else this would fail.First question is how to you do this. Second is there anyway to use a class inside the project as the target of the settings type or do you have to bring a in an external dll to do this every time? [code]

i have a complex object that holds a WPF Canvas with many child canvases, rectangles and, lines. The object includes some home grown classes as well. The main object and the home grown classes have the <Serializable()> attribute set. I tried the general formatter.Serialize(strm, rb_x) to serialize the object to a memory stream. I then found out that WPF classes are set as serializable. So after some research I discovered the System.Runtime.Serialization and found a generic Serialization Surrogate.So after some debugging I was able to serialize the object to a memory stream then copied the stream to an array of bytes then store that array in an OLE field in an MS Access table.
When I read back the access record and copy the OLE field byte array back to a memory stream and then de-serialize it back to the object I get a SerializationException "Error binding to target method."
So question #1 - is what I am trying even possible?Question #2, (assuming #1 is yes) do I need to do something special with WPF Baml type objects.

I have a question about loops that I don't know if it can be done. The program will send data through a parameter to an Oracle DB. What I am trying to do is during a loop I want to be able to send information from one text box, the next time it loops to send information from another text box ect. ect. I was hoping I go do it this way instead of writing out a bunch of parameters in both the program and in Oracle. Can this be done or do I have to write a whole lot of parameters out?

I have various shape objects, and I want each unique shape to implement a saveToDB method that simply calls a DB object that implements a Save method with an object as its input paramter. This DB.Save method will be a long case function that implements the proper SQL commands based on the type of attributes possessed by the input parameter object.how do I implement the SaveToDB method in my Shape class? Is it something like this:
Function Shape.SaveToDB
DB.Save(Me)
End Function
The goal here is to let each shape save itself without it knowing anything about database operations; I want to isolate db-specific information in my intermediary DB object, so the DB object will have to figure out what type of object wants to be saved into the SQL database and then execute whatever SQL instructions are needed. And then if I override the SaveToDB method in each shape subclass, I can avoid the case statement entirely, replacing it with a series of unique methods such as db.SaveCircle (ob), db.SaveSquare (ob), etc., sincle the caller already knows what it is.

I need to pass a block of binary data to a web service. The object I'm passing is part of an API, so the Serialize/Deserialize/Byte functions are built-in to the API class. It is not explicitly XML Serializable as far as I can tell.
Unfortunately, whenever I pass the data to my web service, even as an encoded string, the service returns a "(400) Bad Request" error. If I remove the encoded data and replace the variable with a simple string, an appropriate response is returned, ruling out authentication, service errors, etc.
'Convert the byte array into an encoded string'
Dim unicodeEncoder As New UnicodeEncoding()
Dim serializedData As String = unicodeEncoder.GetString(myObject.Bytes).Trim()
Dim webAuth As New myWebService.ServiceSoapClient
MessageBox.Show(webAuth.VerifyFeatureSet(serializedData , "", "", "", ""))
how I can accomplish this? If I need to encode the data a different way, include a snippet for decoding it on the far end.

I am having a little trouble with the serialport object in VB2008. I have a program that will send a command to the slave device however the program will not read the data from the slave device. I know my computer is communicating with the slave device because in hypertem it has no problem. For example I send the word "AT" and I should get back a response of "OK",

My CrystalReport documents are named same: "PeriodReport1", "PeriodReport2", "PeriodReport3".How can I create and display right type of crystal reports document? I could do something like this:
select case reportName

I have an object, called 'PERSON' This person object has a title, firstName & Surname property as well as many other which are at the moment irrelevant. It also has a read only property called Fullname which concatenates the two or three parameters mentioned above depending on an optional parameter 'withTitles' passed over when you call PERSON.FULLNAME
PERSON.FULLNAME(true) <- Will add titles if there are any
PERSON.FULLNAME(false) <- Will give the name without the title
Public ReadOnly Property FullName(Optional ByVal withTitle As Boolean = False) As String
[Code]...
I get an error: PERSON does not contain a property of 'FullName'. If I change this to any other property that does not take a parameter it works as expected. Now I'm guessing that the binding procedure can't handle optional or mandatory parameters for object properties, is this right? Is there a better way to do it? I thought about looping through the collection to add them manually but that kinda defeats the object of DataBinding!

I'm currently working on being able to import a DLL written in Fortran into Visual Basic. I've got all the basics down, so now I'm trying to take it a step further. The title basically says it all, but I'll explain what it is I'm trying to do anyways.
For kicks and giggles, let's just assume I want to pass an object that has three double values in it, possibly representing a point in space in three dimensions. In my Fortran method, I want to take that object, print out the x value, then change the x value to 7.5. Here's my Fortran code that does just that.[code]...

How can I get the name of the object that was passed byref into a method?
Example:
Dim myobject as object
sub mymethod(byref o as object)
debug.print(o.[RealName!!!!])
end sub
[code]....
I'm using this for logging. I use one method multiple times and it would be nice to log the name of the variable that I passed to it. Since I'm passing it byref, I should be able to get this name, right?This would give you the parameter name in the method and it's type, but not the name of the variable that was passed byref.
using system.reflection
Dim mb As MethodBase = MethodInfo.GetCurrentMethod()
For Each pi As ParameterInfo In mb.GetParameters()
[code]....
If you put that in "mymethod" above you'd get "o" and "Object".

I'm writing a solution where the data entities are passed to clients using datasets through a WCF service, with nHibernate as ORM. My predecessor has written some translator classes, converting datasets to entities and vice versa. In most cases he's declared the return object as a parameter for the object.
For example:
Public Shared Function CreateEntity(ByVal ds As DataSetObject, ByVal entity As EntityObject) As EntityObject
Dim row As ds.EntityObjectRow = ds.EntityObject(0)
entity.Id = row.Id
[code]....
He's not with the company anymore, so I can't ask him why he's done it this way. Hence my question here. Is there some performance gain, or traceablity thing with nHibernate by using the first implementation rather than the latter?

I am having trouble with a mySQL query with the .NET connector. When I create the query, it automatically creates my parameters as objects. I usually change the type to the correct type, which in this case is Date, but I get different results passing in the parameter as a date.When I do "Preview Query" as an object, I get the correct results, but bad results as a Date. I would just leave them as objects, but it errors out when I try to pass a date in.Here's the part of my query that I'm having trouble with:
(Tickets.Resolved >= str_to_date(@startDate, '%m/%d/%Y')) AND (Tickets.Resolved <= str_to_date(@endDate, '%m/%d/%Y')) AND
(Tickets.Status = 'resolved' OR
Tickets.Status = 'rejected')

My problem is that i dont know how to define the parameter type for the sub. Because they are different types of objectSets being passed each time, I thought IObjectSet(Of EntityObject) would work, but it gives me the following error:
Unable to cast object of type 'System.Data.Objects.ObjectSet1[licensingModel.tblLookup_Country]' to
type
'System.Data.Objects.IObjectSet1[System.Data.Objects.DataClasses.EntityObject]'

I made an object that has several properties one of which is an integer.
I put all the objects into a list, and I wish to sort that list by the integer property, with the object with the highest property at item 0, with the object with the lowest property at the highest item # ( count -1).
I made the list of that item, as in
Dim GameList as new list(of clsGame)
And I wish to do something like the following
GameList.Score.Sort()
What is the syntax to do that? I looked up the MSDN and didn't really understand what it was trying to say
