ASP.NET web project -> native DLL -> write failure to hdd

13-Nov-09 11:02

As you dont have reference to Company.MyNameSpace.MyClass, you need to manually read the assembly using Reflection and then using Activator.CreateInstance you create the instance of the class.

For instance :
Assembly assem = Assembly.Load("\folder\MyLib.dll");
object thisObj = assem.CreateInstance("Company.MyNameSpace.MyClass");

I've got ASP.NET web application which uses native DLL in C++ wrapped in C# using PInvoke.
Native DLL needs read/write access to specific folder in site location on hdd.
How to enable it?

e.g. in ASP.NET to enable C# write access to specific folder it needs to allow user to have write access to that folder from folders properties.
with native dll that does not work.

How to register a click event when clicking on a node of a treeview that is already selected

Man Pang13-Nov-09 5:22

When a node in a treeview is clicked, a SelectedNodeChanged event is fired if and only if the node that is clicked is not the same node as the previously selected one. However, if I click on a node that is already selected this event is not fired. Does anybody know how I can find out the node that I had clicked on in this instance.

I can use javascript to trap the onClick event but I still don't know how I can find out which node I clicked, in particular, the ValuePath property of the node.

Thanks, in anticipation.

Access specifier for method

Converting the node into hyperlink would that work ?

Deal all,

I have a method in my aspx.cs file say methodone,which will be called from one of the event or method from the same aspx.cs file...

So what access specifier i can give for that method.I am thinking private is enough for my requirement. AM i correct / wrong? Please provide your views...

Thanks,

If you want to access the method from your html page, you need to make it at least Protected.

I mean if you write
<asp:textbox OnClick="txt_Click" runat="server" />
the txt_click should be made at least protected. Privates cant be used in events.

If you are just calling the method from the class itself, you can use Private. Rose | [Rose]

Can you post the entire Gridview designer?

Did you mentioned DataKeyNames ...

Did you followed this :

Hi,

I am generating an table in code behind and i would like to get it's HTML code so i can include it into an email,
But it doesn't have an innerhtml property.

Thanks

Abhishek Sur13-Nov-09 4:21

Are you using HtmlTable class to make your table ?

If so use

StringBuilder sb = new StringBuilder();
StringWriter tw = new StringWriter(sb);
HtmlTextWriter hw = new HtmlTextWriter(tw);

yourtable.RenderControl(hw);

Now sb will hold the rendered output.
Hope this is what you wanted. Thumbs Up | :thumbsup:

StringWriter and HtmlTextWriter are disposable. It is a good practice to wrap inside using block when working with disposable objects to avoid resource leaks.
