You don't say in what format you want to 'save' the page.

You may be able to render the page using a System.Windows.Forms.WebBrowser control and use that.

My Page renders a simple HTML table generated automatically by some javascript.
I would like to save the rendered page in HTML format so that I can parse it
or reload it later.

Basically, you want a javascript interpreter.

Caveat: I haven't tried this, but I would if I were you Smile | :)

Create a WebBrowser control and give it your [ template HTML / javascript ] using DocumentText. Hook the DocumentComplete event and see what is in the Document property.

I know the WebBrowser control knows how to run javascript, so that's a start.

If you do try this, please let me know if it works - I'm interested Smile | :)

Well
I have just found what I need for my specific purposes; I hope that it fits also yours.
Please have a look at this project The most complete C# Webbrowser wrapper control[^]

Digging and trying I found that this project provides DOM information and is exactly what I need.
I found that you need an active x for accomplish this handling the IHTMLDocument2 class.
PLease look also here column_1[^] and here column_2[^]

Probably I found what I need to do.
I have to download something called DOM information. For my purpose it would be enough.
Do you know how to do that in C# after a web page was loaded?

Hi to all.

How can I easily convert HTML to well formed XML? Does anyone has an idea how I can do that? Thank you for your time.

HtmlAgilityPack has this feature, and it's open source: http://www.codeplex.com/htmlagilitypack[^]
There you will find a project called Html2Xml, perhaps this will help you.

First, since HTML does not conform to XML standards, there is no direct conversion. You'll have to define what you mean by the conversion, what you want converted, and why you think you need this. Perhaps there is another method that will work better than the one your trying.

Are you sure? Ifyou are looking at the data in your application you need to refresh your datasource to see changes. Look directly in the database to see if it has been updated.

As you added this database file to your project did you maybe select "always copy" on the "copy to output directory" property (I don't know the exact phrase in the english studio for this)?
Because this overrides the "modified" database file with the old one (this will be done every time you build your project).

If so, try to use the setting "only if newer".

This happens when a C#.Net windows application is closed. Does anybody know what the possible reasons are ?

.Net App
=========
This is a simple app that loads a VC++ dll to do all the work (decrypt a file, that is the work that it does)

VC++ dll is imported by DllImport as follows:
----------------------------------------------
[System.Runtime.InteropServices.DllImport("decrypt.dll", EntryPoint = "DecryptFile",CallingConvention=System.Runtime.InteropServices.CallingConvention.StdCall)]
public static extern Int32 Decrypt(String ip, String op);

The VC++ method is declared as follows:
-----------------------------------------
__declspec( dllexport ) int __stdcall DecryptFile(LPTSTR ipFile,LPTSTR opFile)

Is there something more to be done to ensure that the imported dll (decrypt.dll) is unloaded ?

In the code a static TCHAR array is used to do the math:
static TCHAR s[1000*32]; // _UNICODE defined. Can this be the problem ?

Re: The instruction at referrenced memory at . The memory could not be read. Click on 'OK' to terminate the program

Covean8-Jan-10 2:01

Because you use LPTSTR (non-constant sting pointer) on the dll-site you should try to use StringBuilder as paramtypes in your DllImport.

[System.Runtime.InteropServices.DllImport("decrypt.dll", EntryPoint = "DecryptFile",CallingConvention=System.Runtime.InteropServices.CallingConvention.StdCall)]
public static extern Int32 Decrypt(StringBuilder ip, StringBuilder op);
