I developed a C# web application that calls a web-service which returns a base64 encoded array (PDF file). I then convert that array into a UCOMIStream object (I know it is obsolete, but the DLL that I am using requires it as a parameter). I use the following code to do the conversion which works perfectly. I can pass this object to the DLL so that I can print the PDF.
This works great on the Webserver, but the requirement is to print it locally.
Byte[] bBuffer = statementOut.statementcycle.statementdata.content;
int size = bBuffer.Length;
IntPtr mem = Marshal.AllocHGlobal(size);
Marshal.Copy(bBuffer, 0, mem, size);
// Create an OLE Stream object.
System.Runtime.InteropServices.UCOMIStream str; //obsolete but the createstreamonhglobal outputs it
CreateStreamOnHGlobal(mem, true, out str);
The DLL resides on the client so I am able to use ActiveX to create the object using javascript and/or VBscript;however, I have not been able to figure out how to get the stream object to the client to pass to the DLL.
I want to write a webservice, and in one of its methods, I want user to pass one my object's instance as parameter. It will greatly reduces number of parameters, and help user call this method more effectively. I create some class, but when distributing them to client, only class name remains, all properties and methods are gone, just like this
public class CameraPackages { private readonly List<CameraPackage> _packages; public CameraPackages() { _packages = new List<CameraPackage>(); } public void AddNewCamera(CameraPackage package) { _packages.Add(package); } public void RemoveCamera(CameraPackage package) { if(_packages.Contains(package)) _packages.Remove(package); else throw new ArgumentException(); } } into this: (in Reference.cs) [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.3082")] [System.SerializableAttribute()] [System.Diagnostics.DebuggerStepThroughAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] [System.Xml.Serialization.XmlTypeAttribute(Namespace="http://tempuri.org/")] public partial class CameraPackages { }
Public selected_Month As String Public Property Month() As String Get Return selected_Month End Get Set(ByVal value As String) selected_Month = value End Set End Property
form1: where i am assigning a value
Dim my_Class As New Class1 my_Class.Month = ddl_Month.Text.ToString() form2: where i am geting a value Dim my_Class2 As New Class1 MessageBox.Show(my_Class2.Month.ToString())
when i run this code, i am getting error like Object reference not set to an instance of an object.
I stucked at a condition , where i need to share values between the pages. I want to share value from Codebehind via little or no javascript. I already have a question here on SO , but using JS. Still did'nt got any result so another approach i am asking.
So I want to know can i pass any .net object in query string. SO that i can unbox it on other end conveniently.
Update
Or is there any JavaScript approach, by passing it to windows modal dialog. or something like that.
What I am doing
What i was doing is that on my parent page load. I am extracting the properties from my class that has values fetched from db. and put it in a Session["mySession"]. Some thing like this.
Session["mySession"] = myClass.myStatus which is List<int>;
Now on one my event that checkbox click event from client side, i am opening a popup. and on its page load, extracting the list and filling the checkbox list on the child page.
Now from here user can modify its selection and close this page. Close is done via a button called save , on which i am iterating through the checked items and again sending it in Session["mySession"].
But the problem is here , when ever i again click on radio button to view the updated values , it displays the previous one. That is , If my total count of list is 3 from the db, and after modification it is 1. After reopening it still displays 3 instead of 1.
I am doing a project in ASP.NET MVC in which I want to implement an IoC container. I am new to IoC containers and have been searching to find a solution to my problem, but so far to no avail.
The problem is dat data is distributed across various databases. Once a user is logged in, the database for the user is retrieved from an authorization database and then set in the user session. That user session is passed on to the services and repositories when they are constructed, so they can use it when they need it to access the database.
A typical bare stripped service (without interfaces and ioc) looks like this:
private CompetitionRepository _CompetitionRepo; public CompetitionService(DataContext dataContext) : this (new CompetitionRepository(dataContext)) { }
[code]...
The "DataContext" contains a couple of properties with which the correct database is selected for the session. Because the Services and Repositories don't have access to the session itself (which is outside of their scope) they need this object.
I have an array which contains around 50-200 hyperlinks. How can I pass this array to the client-side so that I can iterate through the array and display each hyperlinks as a list item? The array will be stored in 'Application' as it's system wide and rarely changes. Could there be a more efficient way of achieving the hyperlinks as a list?
I need to pass div client id to JavaScript of a repeater

I need to use this data as an input to ajax request. For eg. consider a dropdownlist change event, I need to pass these values to the controller.
sample code
//dropdown change event $("#TestReqID").change(function() { var id = 10; var testResults = "abc"; var inXML = "<xml>"; inXML = inXML + "<id>" + id + "</id>"; inXML = inXML + "<value1>" + testResults + "</value1>"; inXML = inXML + "</xml>" $.getJSON("/Home/UpdateTest/Json/" + inXML, function(data) { //success code goes here }); });
in HomeController
public ActionResult UpdateTest(string obj) { if (HttpContext.Request.IsAjaxRequest()) { /* Need to parse data in "obj" from ajax request */ IPTests test = _service.GetIPTest(Convert.ToInt32(id)); return new JsonResult { Data = new { ipTestId = "0", testResults = "" } }; } return View(test); }
instead of xml string is it possible to use javascript object like
I am trying to pass a sql connection object by reference ("ByRef") like so but when I'm inside the function that i'm passing it to it sees the connection as closed, what am i doing wrong?
In a GridView, I am using ItemTemplate section for multiple editing. I am using ClientValidationFunction property of MaskedEditExtender to run a client side function. Let's call it MyClientFunction . How can I pass an ID of a control found in the gridview row to my MyClientFunction?
I know how to do it via RowDataBound as follows: Is there a way to wire it up in ClientValidationFunction property?
Dim NewDte As TextBox Dim PrvDte As Label NewDte = CType(e.Row.FindControl("EditReadingDate"), TextBox) PrvDte = CType(e.Row.FindControl("lblEditLstRdgDte"), Label) NewDte.Attributes.Add("onkeyup", "javascript:ChkDteMultiple('" & PrvDte.ClientID & "')")

First, we are constrained to using an existing web framework that handles authentication and authorization. The web project uses forms authentication and writes to an encrypted cookie. The user information is exposed to the aspx pages as a property:
LoggedInUser.Current
This has several properties including the userId and role list.
I've looked at using initParams, but haven't been very successful there (edit: I couldn't do it dynamically originally). I've created a simple POCO entity with a [Key] attribute, but I need to at least be able to pass the userId from the aspx page to the imbedded silverlight.
What is the easiest way to pass a dynamic object from aspx to silverlight 4?
[Code]....
Then used Slugster's example to use the values on the Silverlight side.
Warning: Passing user information via init params exposes the info as plain text to the user viewing the page (they just have to view the source). We ended up using an authentication domain service and using the same user object as the aspx
I'm using a CustomValidator control to validate some controls in a GridView. I have the validation working perfectly on the client and the server, but would ideally like to pass the GridView ID into the client function so I can move it out into a separate
.js file. The signature for my client function is:
function valOrder_ClientValidate(source, args) { // Code here}
And my CustomValidator control looks like:
[Code]....
Is there a way I can pass an additional parameter into this function?
I have run into the issue on DataSet.WriteXml method. Apparently, if any row in a column in the DataSet has a null value, the entire column/rows will not write out in the xml file using the method DataSet.WriteXml. So, as terrible as that bug is, I need to send the data another way. Does anyone have any thoughts?
But I get the error message that I can't create an object of the type System.TypeCode from the string containing SB.BusinessLogic.DomainEntity.User for the property Type.
im just testing out signalr and i am having too much fun and got a little bit far from my usual skill now my question is can i pass a list to the client here is my code actually i learned this from you mr aspsinnipets
