I am creating a web application with back-end on ISeries.In the page load I am populating a datatable and using it as a datasource for my gridview.
What is the best possible way to access the data in the datatable from other methods, on the same page? And in other pages?
The way I do currently is to get data from the gridview and populate in another datatable and then use it... Is there a better (elegant) way to do that?
I have a main MasterPage that, as intended, forms the entire layout of my site. It has a bunch of methods common to all pages that use the mastertype, such as EnsureLoggedIn and such.
I want to move on to using nested masterpages to open up better layout options in some of the pages, but I am running into an issue. I get the layout of the nested masterpages fine, but I cannot access any methods in the parent masterpage.
I know my explanation seems a little sparse; I'm not exactly sure how to word what I'm looking for, heh. But here's a short example:
public static class PageExtensions { public static int GetUserId(this Page targetPage) { var user = Membership.GetUser(targetPage.User.Identity.Name); return (int)user.ProviderUserKey; } }
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId() { return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey; }
and I call it as follows in my WebMethod: PageExtensions.GetUserId()
I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.
i have the dataset with one table.Table contains three column like 'Name','Location','Pin'.I would like to move the data from another table based on schema.
If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
im trying to copying specific record from one datatable to another datatable i used below code
public System.Data.DataTable selectspecificdatarow(System.Data.DataTable dtg, int count, int startindex) { System.Data.DataTable dtn = dtg.Clone(); for (int i =startindex; i < count; i++)
[Code]....
its taking too long time in cloneing is there any better way to do this task which is Time effecent
i have a repository class inside my model folder; this repositiry contains many methods , which are called from Action methods in the controllers; so my question is :- if i have a method insidle my model.reporsitory which calls a stored procedure, then can i call it an "action method"? or "action method" expression only apply to controller methods?
how to join two datatable datas into one datatable to show in one gridview
i.e in 1 datatable i have username and pwd and in another datatable i have that user details. how to show all these in one datatable to get those values display in gridview(asp.net)
We say that "GroupBy" and "OrderBy" methods from LINQ as Extension Methods.Then how about "variable.ToString()" and "string.Split()" menthods. Are these Extension methods.
Dim dt As New DataTable Dim da As New SqlDataAdapter(s, c)
c.Open() if Not IsNothing(da) Then da.Fill(dt)
[code]...
When I call da.fill I am inserting all records from my query. I was then hoping to filter them to display only those where the GroupingID is equal to 0. When I run the above code. I am presented with all the data, the filter did not work. Please can you tell me how to get this working correctly.
I have a DataTable of available time slots. I have another DataTable of reserved time slots. I need to remove from the list of available slots the ones that have been reserved. The blocks are in 15 minute increments, but one of my problems is that the reservation can be longer than 15 minutes. I've had some luck removing one or two, but not all of the required columns.
I have two datatables, I want to get all records which are in one datatable but all matching records which exist in another datatable should not be available.
In terms of set, you can say that record which are in 1st datatable but not in 2nd DataTable.
I have a datatable with 17 columns and a bunch of data. I wnat a datatable with only 6 of the columns and the data for those 6 columns. So I need a subset of the original datatable. How do I loop through the original datatable with 17 columns and end up with a datatable with only the 6 columns I want with the corresponding data for those 6 columns?
Below is a beginning attempt to increment through a DataTable populated by a Stored Procedure and create a new DataTable where every Category is represented by exactly four products. I need to add dummy product entries for some and skip over those with over four products.
A) - I think I understand the basics but this builing from scratch is not my practice. 1) I do not know how to query a previous row in reference DataTable. 2) I do not know how to jump to next row from IF construct. 3) I hope I am able to build a DataTable row by row. 4) Partial sample data is at bottom of pseudo code
There has to be an easy answer:I want to loop through multiple datatables... example:
for (int i = 1 ; i < 7 ; i ++ ) { DataTable dt = (DataTable) "dt" + i.toString(); // do something with DataTable dt1 as DataTable // ie... int x = dt.Rows.Count }
The above code obviously does not work.. but how do you find a DataTable like you do FindControl with WebControls??
I developed a DLL in C# When I am trying to call it I get: System.EntryPointNotFoundException: Unable to find an entry point named: It means that DLL doens't export any methods visible from DLL. Dumpbin doesn't show any methods either:
What's wrong? The DLL looks ok.. according to documentation:
Csharp Code: namespace Kosmala.Michal.ActiveXTest public static void setHooks() { .... } Here is how I call it: Csharp Code: namespace IWFHotkeyStarter { class Program { [DllImport("D:\work\iwf\_ctrl-tab-modless_dlg_testing\activex\VSProjects\AcriveXSourceCode\bin\Debug\ActiveXTest.dll")] public extern static void setHooks(); static void Main(string[] args) { Program p = new Program(); p.run(); } private void run(){ Console.WriteLine("run<<"); setHooks(); Console.WriteLine("run>>"); } } }
I was trying to overload two web methods by adding the MessagName descriptor.
[WebMethod(MessageName = "GetFiles")] public [Code]....
But I am getting the following Server Error

I have an ASP.NET web application and I'm thinking about the following: before sending any HTML or CSS content to users, I wish to 'compress' them, then cache the result and send that to the clients.I know it is possible to compress these by removing whitespaces, comments and stuff like that, but I'm not really familiar with more advanced solutions for this.
Apart from this, what compression methods are there and what are the advantages of each of them?Does some browsers or the HTTP protocol itself support any kind of compression?
EDIT: I'm interested in doing this to dynamically-generated HTML, too.
