my current machine dns suffixname.I would like to connect to remote host through tcp protocol socket.

Your DNS suffix is not going to help you to connect to a remote host; you need to know the name or IP address of the remote system itself.

anyone know how to use ref to make this work?
i keep getting error on load<item3>(i.Item2);
i tried using ref but it didnt work.
public static List<Tuple<object,string,Type>> DBlist;
DBlist.Add(new Tuple<object, string, Type>(A, "A", typeof(List<Car>)));
DBlist.Add(new Tuple<object, string, Type>(B, "B", typeof(List<Boat>)));
foreach (Tuple<Object, string, Type> i in DBlist)
{
Type temp = i.Item3;
i.Item1 = load<Item3>(i.Item2);
}
public static T load<T>(string tablename)

What error are you getting? "It didn't work" is hardly enough information for anyone to help you.
The difficult we do right away...

|
|
|
|
|
i.Item1 = load<Item3>(i.Item2);
i.Item1 = load<Type>(i.Item2);
|
|
|
|
|
It should be rather
i.Item1 = load<temp>(i.Item2);
or
i.Item1 = load<i.Item3>(i.Item2);
The good thing about pessimism is, that you are always either right or pleasently surprised.

So you want to call a generic method with a dynamic type parameter? You'll need to use reflection to do that.
Try something like this:
MethodInfo baseMethod = typeof(YourClass).GetMethod("load",
BindingFlags.Public | BindingFlags.Static,
null,
new[] { typeof(string) },
null);
foreach (Tuple<object, string, Type> i in DBlist)
{
MethodInfo realMethod = baseMethod.MakeGenericMethod(i.Item3);
i.Item1 = realMethod.Invoke(null, new[] { i.Item2 });
}
Where YourClass is the name of the class which contains the load<T> method.

You have several problems, as Richard Deeming noted you can't use the load that way, you'll need to use Reflection.
Also, it looks like you intend to assign the result of the load into the variable referenced by the .Item1 object of the Tuple.
What your code actually does is try to assign into the .Item1 property of the Tuple.
Tuples, once created, cannot be changed. The .Item1 property is get-only.
You might be better off changing the DBList to hold delegates that actually do what you seem to want to happen.
Something like:
public static List<Action> DBList;
DBList.Add(() => A = load<<Car>>("A"));
DBList.Add(() => B = load<Boat>("B"));
foreach (var loader in DBList)
{
loader();
}
public static List<T> load<T>(string tablename)

I have a web service where I need to create a very large bitmap 15,000 x 15,900 x 32bpp. Code fails on my machine (Parameter is not valid exception). On the IIS server, I can create about 85 or so before I get the Parameter is not valid exception. I do NOT keep all 85 in memory if that was your next question  .
Workflow is pretty much:
1) Get image request
2) Create 15,000 x 15,900 x 32bpp bitmap
3) Do stuff to it
4) Convert it to 1bpp and return the bytes
I've changed my code around so I call Dispose() on the various Graphics objects every step of the way the second I don't need them anymore, but no luck. The bitmap in Step #2 has to be 32bpp.
Originally I had 10,000 x 10,900 bitmaps and I could process a whole set without crashing (710+). Unfortunately, QA requested the bitmaps to be 15,000 x 15,900. Trying to see how far I get by dropping to 14,000 x 14,900.
I suspect this has to do with the Large Object Heap fragmentation?
One of the recomendations I've seen on the net is to just create a single 15,000 x 15,900 object and re-use it.
Not sure how that would work in a web service. Each simultaneous request needs a 15,000 x 15,900 bitmap of its own.
Saw there is something in .NET 4.5.1 to compact the large object heap... might try that next if the 14k images don't work.

Check your project, are you compiling it for x64, or using AnyCPU? In order to make it be a 64 bit app, everything must be set to x64, or AnyCPU and running on a 64 bit box. Then make sure that the process is a 64 bit process.
I am assuming you have already done that.
|
|
|
|
|
Yeah, I'm compiling everything as AnyCPU. I think it's something with the fragmentation.

Save it to disk; what's the resulting filesize? A Gb?

Is it going to be requested often? What frequency?

After I convert to 1bpp, the resulting TIF is only 1MB to 2MB, but a 15,000 x 15,000 x 32 bpp is like 800MB to 900MB in memory.

You could do the operation in a separate appdomain (or a separate executable). One can unload an AppDomain, but a separate executable would have to release it's memory on termination.

Try GC.WaitForPendingFinalizers in addition to GC.Collect and Dispose.

What code are you using to create the Bitmap?

I am not sure if there is an easy way to compile the codes. I have created 1 exe and 4 dlls.
The exe relies (depends) on 4 dlls ('a', 'b', 'c', 'd').
Illustration is as shown below:
exe -> 'a' -> 'c' -> 'd'
-> 'b' ----^
The 'd' dll is the lowest level. The 'd' is referenced in 'c' dll. and so on. Also that 'a' and 'b' dlls are referenced in exe.
Now when making changes in 'c' dll, I would compile the exe but the 'c' dll remains previous version, not updated when compiling the exe. I would have to compile each dlls ('a', and 'b') then the exe so that the updated 'c' dll is passed over to the exe.
Now for the question is there the easy way to compile those dlls at once? Thanks!
<edited>: Forgot to add that I'm using Visual Studio 2010

If you right click on a project in the solution explorer, there's a menu item "Project Dependencies[^]". There you can set which projects a project depends on, and a right compilation order will be figured out based on that.

Found it.. but not sure how to add items in project dependencies. The thing is that the those dlls are seperated (independent) in other folders... I think I need to put those dll projects in the exe project.
Am I right?
|
|
|
|
|
Thanks! Now that the solution is much easier to work on and compiling! THANKS A HEAP!
|
|

If you're using Visual Studio, you can configure the project dependencies.
Right-click the solution file in Solution Explorer, and choose Properties.
Then go to the "Project Dependencies" set of options.
Set the dependencies so that a depends upon b, and b depends upon c, and so forth.

Hey Guys
I am looking for code in asp.net for making user log out if he have open application in multiple tab and log out from one tab then from remaining tab also user should log out how to achieve
like gmail,facebook.
thanks

You can't force a user to log out, the most (worst) you can do is pop a message box confirming navigation away from the app.

Hello,
I have written the code below. How do I get the "public List<tbl_objecten_tbl_nen2634> TheList" loaded first?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Bouwgegevens.Gebouwen
{
public partial class Plan : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!ScriptManager.GetCurrent(this).IsInAsyncPostBack)
{
PopulateMenu();
}
else
{
}
}
private void PopulateMenu()
{
List<tbl_NEN2634> allMenu = new List<tbl_NEN2634>();
using (DBBouwgegevensEntities dc = new DBBouwgegevensEntities())
{
allMenu = dc.tbl_NEN2634.ToList();
}
CreateTreeView(allMenu, 0, null);
}
public List<tbl_Objecten_tbl_NEN2634> TheList
{
get;set;
}
private void CreateTreeView(List<tbl_NEN2634> source, int parentID, TreeNode parentNode)
{
int objectID = Convert.ToInt32(Request.QueryString["ObjectID"]);
List<tbl_NEN2634> newSource = (from b in source
join c in TheList
on b.NEN2634ID equals c.NEN2634ID
where b.ParentID == parentID
select b).ToList();
foreach (var i in newSource)
{
TreeNode newnode = new TreeNode("" + i.NEN2634_Code + "" + " " + i.NEN2634_Titel, i.NEN2634ID.ToString());
if (parentNode == null)
{
trvPlan.Nodes.Add(newnode);
}
else
{
parentNode.ChildNodes.Add(newnode);
}
CreateTreeView(source, i.NEN2634ID, newnode);
}
}
}
}
Please help,
Kind regards
