  • ASP.NET MVC: calling a controller method from view

    - by Alice in wonderland
    I'm implementing paging on an ASP.NET MVC view, and I want to call a method in the controller from the view. Code in the view: <a href="<%= Url.Action("Search", new { page = NextPage(Request["exactPage"])).ToString()}) %>"> Controller method: public string NextPage(string currentPage) { return (int.Parse(currentPage) + 1).ToString(); } How can I call the NextPage method from the view? thanks!

  • Difference between DirectCast() and CType() in VB.Net

    - by Chapso
    I am an experienced C/C++/C# programmer who has just gotten into VB.NET. I generally use CType (and CInt, CBool, CStr) for casts because it is less characters and was the first way of casting which I was exposed to, but I am aware of DirectCast and TryCast as well. Simply, are there any differences (effect of cast, performance, etc.) between DirectCast and CType? I understand the idea of TryCast.

  • ASP.NET: Using Session to store authentication?

    - by Niels Bosma
    I'm having a lot of problems with FormsAuthentication (http://stackoverflow.com/questions/2964342/problem-with-asp-net-authentication) and as as potential work around I'm thinking about storing the login in the Session? Login: Session["Auth.ClientId"] = clientId; IsAuthenticated: Session["Auth.ClientId"] != null; Logout; Session["Auth.ClientId"] == null; I'm not really using most of the bells and whistles of FormsAuthentication anyway. Is this a bad idea?

  • VB.NET Function Return

    - by waves
    In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value." I sometimes see these inter-mixed in the same function. Personally, I prefer the return. My question is, what is the internal difference, if any, between the two?

  • Call two Matlab functions simultaneously from .net

    - by Silv3rSurf
    I am writing a C# application and I would like to make calls to different matlab functions simultaneously(from different threads). Each Matlab function is located in its own compiled .net library. It seems that I am only able to call one Matlab function at a time however. ie, if matlab_func1() gets called from thread1 then matlab_func2() gets called from thread2, matlab_func2() must wait for matlab_func1() to finish executing. Is there a way to call different matlab functions simultaneously? Thanks.

Not very useful. Any ideas? Thanks, Alex

  • How to draw a single point with .Net?

    - by SoMoS
    Hello, this should be pretty simple but I don't get it. How can I draw a single point in .Net? If I use g.DrawLine(Black,0,0,0,0) nothing is drawn and if I use g.DrawLine(Black,0,0,1,0) a line with 2 dots is used. The same happens with g.DrawRectangle. This has me intrigued. Thanks in advance.
