View 12 RepliesUsing MySQL 5.
In my SAP.NEt project, defined a constant:
public static DateTime NullDateTime = DateTime.MinValue;
I have a function:
protected static DateTime GetDateTime(DataRow row, string columnName)
{
return (row[columnName] != DBNull.Value) ?
Convert.ToDateTime(row[columnName]) :
Globals.NullDateTime;
}
In the source code:
public DateTime StationFeedTime{ get; set; }
StationFeedTime = GetDateTime(row, "StationFeedTime");
I ran a SQL to fetch records from MySQL, this field is Time field in MySQL.
Got an exception inside the function:
Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.

View 1 RepliesI am writing an application that does it's own logging in a SQL table. On each page, I statically assign this variable: Dim page = "page_01.aspx" I've noticed that page is ALWAYS equal to the name of the Partial Class of the code-behind + the suffix ".aspx" Is there any way to programatically set the string to equal the name of the Partial Class, so I don't have to statically code it on each page? Basically, I want to assign the name of the current class to a string, and append ".aspx" to it. Can I do this, or does that get lost in the compilation?
View 1 RepliesClass file Conflicts in C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files is preventing me from building the solution. Even though I try emptying out the folder, each time Visual Studio starts the build process, it brings in the class file in to the temp folder with the same folder name. If I restart the machine or leave it overnight, project build without error. Is there anyway to tell Visual studio to delete/ignore/clean any lingering class files that could be in the temp folder?
Clean solution option in VS doesn't work either. Class file in conflict are from the App_Code folder.
I am trying to develop logic to add dynamic controls to page via class method. So I want to know how can we access the ASP.Net Page object reference in class method.
View 1 Repliesmy MasterPage I have a label that reflects the name of the module that the user is currently in. I change the label text accordingly using the following ..
private void ChangePageTitle(string PageTitle)
{
Label lblPageTitle = (Label)Master.FindControl("lblPageTitle");
lblPageTitle.Text = PageTitle;
}
Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?
I am developing a web applications. The application was intially done in Visual studio 2003 using csharp. then it was upgraded to visual stduio 2008.

View 6 RepliesUsing ASP.NET v3.5 / VS2008.
Is there a way to share class files across web site projects without actually making a physical copy of the file to the App_Code folder of each project?
I lifted some nice code to handle memberships, but I want to add a customer specific field. My issue is how to reference my class from the inline c# code.
[Code]....
The problem is the line csUserProperties.AddNew(intUserId, lngCustomerId); -- I get the error "The name 'csUserProperties' does not exist in the current context. I have <%@ Import Namespace="csUserProperties" %> at the top of the file. I also tried everything with no namespace in the class below.
I am tasked with customizing a third-party web application. Since the application is updated (ie new files are copied over the existing files) several times a year, I was hoping that I could put my custom code in separate files -- sort of like having asecond code-behind file for each page that is modified.
View 2 RepliesI have a Web Site project running on VD2008, with an Access back end and .NET 3.5, C#.
I have created the project several times and added the usual App_Code, Pages, App_Data, Properties, folders. I created a Master Page and several content pages BUT I am unable to get to the folders or root where there is a Class (code) file.
I have tried all the usual lines...
using SumaCard.App_Code
OR

What have I missed? Maybe I built the project wrongly? (Project | New Project | Visual C# | Web | ASP.NET Web Application |??

View 1 RepliesI'm reading a bit of Pro ASP.NET MVC Framework and following a few tutorials written in the book. In the very first tutorial, creating a MVC site for dinner (PartyInvites), I encoutered this problem. While I try to reference some properties from Model class, the compilation error occured. Eg. the following code failed.
[Code]....
and the error message
Compiler Error Message:
CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) I imported the Model folder into the controller too. I dunno what I'm missing here. Sorry, if it sounds a bit umm hard to understand cuz I just started picking up MVC this morning. Looking for any input.
Why do we use the reference of abstract class (or base class) to create object of it's sub-class. eg: TextWriter is the abstract class for StreamWriter & StreamWriter.
TextWriter writer = new StreamWriter();
why can't we simply use :
StreamWriter writer = new StreamWriter();
I'm working on an internet application that has been set up as a web SITE project (I know...) in Visual Studio. I need to add additional features/functionality so have added a class library to the project and referred to it in the main web site project.
The issue now arises because I need to make use of core objects which live inside the App_Code directory in the web site project but this project doesn't appear to expose its DLL like web app/ code library projects do. Because of this I can't add a reference to the web site project in the class library to leverage the common site-wide code/objects.
I can't move the stuff out of App_Code so I'm looking for a way to refer to the website project dll from the new class library.
i need to search and find in dropdown list in my project a lot of times, so i wrote a function
Public Overloads Function findInList(ByVal strValue As String, ByRef ddl As DropDownList, ByVal findType As ddlFindtype) As Integer
Try
If findType = ddlFindtype.byText Then
Dim li As ListItem = ddl.Items.FindByText(strValue)[code]...
it is in a class and obviously it is not working,the ddl is loaded in a aspx page , and it is passed to this function as reference.the ddl as reference is not containing its values from the aspx page.
i need to what i am doing is correct, or is there any other way to achieve it.
i've created a dataset, and created inside it a datatable and its table adapter.

I have this method that I'm currently putting in each page I make, I know there should be a good way to move it to a single place for ease of maintenance and simplicity. I'm just not sure how I should handle the event handler. The event handler needs to be on each page, so how would I pass in a reference to the page properly so I can reference the event handler?
private void InsertLinkButton(string text, string id, UpdatePanel updateSummary)
{
LinkButton link = new LinkButton();
link.Text = text;
link.Click += new EventHandler(link_Click); <------
link.CausesValidation = false;
AsyncPostBackTrigger trigger = new AsyncPostBackTrigger();
trigger.ControlID = link.ID = "link" + id;
trigger.EventName = "Click";
Utils.Tag(link, placeHolderSummary);
updateSummary.Triggers.Add(trigger);
}
This is an ASP.NET 2010 web app written in vb. I use several Session variables. I want to pass them all to a central class and let the class manage them. However, I am having some trouble.
Here is the code on the calling page:
Dim arrGoodSessions() As String ={"nameofsession1", "nameofsession2", "nameofsession3"}
Utilities.ManageSessionVariables(arrGoodSessions)
It calls that static Utilties class. I have set a reference to System.Web. Here is the code in the class:
Imports System.Web
Imports System.Web.SessionState
Imports System.Web.SessionState.HttpSessionState
Imports System.Web.HttpContext
[Code]....
This attempts to simply read in some names of session variables and then cycle through all session variables and remove any I didn't list. This works when all of the cod eis on the page. But when I move this to the class, it doesn't recgonize Session.Contents.
When should I go for creating a proxy class for a web service and when should I go for adding web reference to web service.
Are there any specific advantages of using proxy class over web reference?
I have a simple class in asp.net mvc that looks like this:
[code]...
It deserializes it so I have to reference everything by index first, because of the list. So if I had a property called "IsValid" I would have to reference it like this "IsValid[0]". I have way too much javascript code to make these changes.How could I deserialize the JsonResponseItem class so I don't need the index reference in there?
