C# - Is There Any Limit On Number Of Classes That A Namespace Can Have In .net ?
Aug 9, 2010
Is there any limit on number of classes that a namespace can have in .net ? Further what is the recommended number of classes that there should be in a namespace?
If I included a page class into a namespace the Profile page property becomes undefined.Why and how to solve this problem.For example I want to include my pages classes into a namespace MyProject.UI.
I keep getting the error: Error message: CS0101: The namespace '<global namespace>' already contains a definition for 'checkvalue'. Then, I rename the Inherits from the @page directive in both the .aspx and .aspx.cs pages and it works! My website has only 2 pages, and both use the same class (same class name, exactly same syntax) but it has been copied and pasted and the 2 aspx pages (and aspx.cs pages) are not referencing each other. In other words, both aspx.cs pages (called page1.aspx.cs and page2.aspx.cs) has the class
public class CheckValue { //content return true; }
Both the aspx pages reference the 'inherits' files seperately:
Any limit to the number of nodes you can have in a treeview, I have been having some problems getting it to display with the panel I made. I have actually decided not to use the treeview, in fact may drop this part of the app altogether, but just wondering for future reference. I know if certain browsers have a limit for the the url, but can not seem to find anything, if there is anything, on a node limit. I am using asp.net 3.5 with VB and my browser is IE8, well the only one I tested on.
On my products page I have a small thumbnail and a description that is pulled from the database, since there is space restraints, how do I allow a max amount of characters, and if the description is longer append ... to the end? I'm using a data repeater and data binding for the content inside it.
I have notice that the UpdatePanel post every field included on the form on every trigger.
But in most of my cases I use 2-3 UpdatePanels at the same page, and each one is independent.
When I click for update the one panel, then my page receive all the input data of the page (ok this is logical) but I won to read only this UpdatePanels data and act according, and not the other panels data.
So I see that a lot of traffic is happened this way.
So is there a way to say to one UpdatePanel - send only my input data, and not everything found on the page. ?
I have a dropdown list. This is a bound to a column in Table which has around 200 entires.Now when a user clicks on the drop down list I want him to see not more than 10 rows. The rest he should navigate by using scroll bars.
I have a html.dropdownlist on my webpage as follows: <%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%> I am populating the dropdown with ~80 items. The issue is that when I click the dropdown the list of items is rendered from the top of the screen to the bottom of the screen. How can I set up the dropdownlist so that it only displays a maximum of 20 items when the dropdown menu is clicked (i.e. user needs to scroll down to see items 21 - 80)?
I was anticipating (!) that there would be a html.dropdownlist property to control the number of displayed items that would allow something like the following e.g.: <% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %> From research I have been doing on the msdn website it appears that there is no such property and that each browser has its own rules of how many items are displayed in a dropdownlist (?).
I have a report, which has two sections namely Labour and Spares.In labour section no of records per page must be limited to 5 records and the Spares section have to limit to 10 records per page.If either Labour or Parts exceed the max limit the records must be shown in the next page. Limiting one section by using formulas can be done easily ...but it is very difficult control two sections simultaneously.
I am trying to find a solution to control the number of logins on asp.net application. I need to install the application in the client server, and set the number of licences. e.g. only 10 users are allowed to access the app.
Every time someone tries to login I need to check how many user are logged in, compare with the total allowed then authorize that user to proceed.
I tried with Certificate, but I couldn't see where to match the number of logged in users with the max number of allowed user.
Also I would like to use the IP address as identifier, then if I open 3 browser windows, it count only one user logged.
Basically this web application will be sold by licences. We need to control the logins per computer, and not per user, and block logins if the limit of logins are reached.
I'm trying to read a CSV file into a DataTable using OleDbConnection and OleDbDataAdapter. It works loading the DataTable, but only does 255 columns. The file has 362 columns.
In my text area, I should be able to enter only 72 characters per line. If I use, cols property set to 72, it is allowing more or less number of characters depending on character width.
Is there a technical/performance limit on the number of roles an application handles? I'm in the process of designing an application which I forsee having a lot of roles created, to be able to handle the degree of granularity the system should have (e.g., permissions per project, where there could be a lot of projects).
Would you recommend another approach other than using roles for this kind of granularity?
is there is any methos so that only the some data rows displayed in detaisview.and rest of the data row item will appear by clicking more button or link.
I'm creating a login page. I want to limit the number of login attempts, say not more than 5, in case of wrong.I want to do it without using the asp:loghin controls and the membership.How can restrict it??
Today my client asked to implement SMS Counter and restriction to 150 characters in SMSalert.aspx form,I have done only Validation Control. I am working with SMS for the first time.
I have just started to look at the new "System.Threading.Tasks" goodness in .Net 4.0, and would like to know if there is any build in support for limiting the number of concurrent tasks that run at once, or if this should be manually handled.
E.G: If I need to call a calculation method 100 times, is there a way to set up 100 Tasks, but have only 5 execute simultaneously? The answer may just be to create 5 tasks, call Task.WaitAny, and create a new Task as each previous one finishes. I just want to make sure I am not missing a trick if there is a better way to do this.
