Hi,
I have written code that executes within a Windows.Forms application but fails when the code is run within a WebService.
I add a reference to the SHDocVw.dll windows library.
The common code is as follows:
System.Object nullObject = 0;<br />
System.Object nullObjStr = "";<br />
string url = @"https://www.123456789.com";<br />
<br />
InternetExplorer ie = new InternetExplorerClass();<br />
<br />
ie.Navigate(url, ref nullObject, ref nullObjStr, ref nullObjStr, ref nullObjStr);<br />
<br />
<br />
while( ie.ReadyState != tagREADYSTATE.READYSTATE_COMPLETE )<br />
{<br />
System.Threading.Thread.Sleep(1000);<br />
count++;<br />
if (count > 30)<br />
{<br />
return null;<br />
}<br />
}<br />
<br />
return (ie.Document as IHTMLDocument2).body.outerText;
The code runs fine in the windows application but raises this exception in a WebService
System.Runtime.InteropServices.COMException (0x800706BF): The remote procedure call failed and did not execute.<br />
at SHDocVw.InternetExplorerClass.get_ReadyState()
Does anyone have any ideas about this problem?

Do you have to use the IE webcontrol? I think a better way to do it would be this:
using System.Text;
using System.Net;
class Demo
{
public static string GetPage()
{
System.Net.WebClient client = new System.Web.WebClient();
byte[] resultSet = client.DownloadData("https://www.123456789.com");
Encoding myEncoding = Encoding.Default;
return myEncoding.GetString(resultSet);
}
}That'll get you the HTML for the page...and it's all managed, no COM Interop needed.

I have tried to use the WebClient, WebRebRequest and WebResponse classes with the URI that I am trying to retrieve. All of these classes return an invalid request response from the server. The method I have shown works with the URI.

Are you sure you have the Network credentials right? The https protocol uses a username and password that you may have to pass through in the Credentials property.

Yes ... Done all that stuff b4 .. The URI contains the credentials in this case. As I stated before the URI works in Internet Explorer and with the code shown in my first post, but not within a WebService. My guess is that the problem is the security context in which the WebService runs.

I am looking for "Class hierarchy visualization tool" for C#. Earlier I used a product called CodeVizor[^] for VC++ (also supports Java), but now it looks like that company[^] gave up on that product.
Do you know any tool like that for VC++.NET and C#.NET?

No.
I tried the Reflector.
The beauty of CodeVizor is it produces class hierarchy chart just like the MFC classes posters (parent/child relationships). This chart can be printed and tacked onto the wall.
That makes easy to reference for the whole team.
Don't and drive.

Hmmm I see, and no then I havent seen such a tool, but Visio could probably do it if you have it.
[edit] Did you look at the outline option in Reflector, its not graphs as such, but it mite be sufficient for your needs [edit]

True I'm gonna have a look at GraphViz and see if I can do something usefull. Maybe possible to do a plugin for Reflector

What details are you looking for exactly? I can generate a tool to make real nice inheritance structures. Just give me all you require and maybe some ideas.

If you download ASP .NET Web Matrix, it comes with a Class Browser. It shows the class hierarchy w/ each "ancestor" being a hyperlink to that class's def. The thing I don't like is that you can't just do a one-time viewing of an assembly, except by loading it in and then unloading it from the list when you're done.
I don't think it has exactly what you're looking for, though.

Looks good. I didn't know about this one. Thx for the tip.
It supports print options, but the print menu items were disabled.

Object Browser which is embedded in visual studio.Net IDE is sufficient for your purpose. Don't look for any other thing.
Go use and enjoy
I hope that's what you were looking for!

I want a tool which allows to view Class/namespace hierarchy and also PRINT like Microsoft classes posters. (CodeVizor does that for VC++ and Java)

i am a newbie at c#, but have a good amount of time with vc++ development.. can someone help me with some questions?
in vc++ my application could have variables and functions like:
CCompanyStore* myCompanyStore;
void ShowAboutDialog(); and i would call them throughout the program like:
CMyApp* pApp = (CMyApp*)AfxGetApp();
pApp->ShowAboutDialog(); i would use these types of functions for replacing views in my mainframe and such as well.. but i dont understand how to call a function from my base form without doing something stupid like calling this.Parent.Parent.SetStatusText("hello");..
is there an easy way to get a pointer or a handle onto the main form i have derived from System.Windows.Forms.Form to call its functions or get/set its variables?
thanks in advance for any pointers!
EDIT: just to clarify, i want to be able to call functions from anywhere in the program to set the status bar text, or to enable/disable a toolbar button, or to replace the form displayed in the background, etc.

Remember that everything in C# is defined in a class. So, check out the static[^] keyword. I believe that is what you want. Here[^] is another reference.

i guess the static variables would work for maintaining application variables, but i still dont understand how i would access the variable of that class type if it is a member variable of my main form..
basicly if i have a function which sets what is being displayed in my main form i would want to be able to call that function from another form..
still a newb.. cut me some slack :P

The equivalent of AfxGetApp is the .NET Application class, which holds the ApplicationContext and the MainForm.
Unfortunately, the ApplicationContext member is not visible from your own code (it's protected).

so is there another way to get a handle on the main form?

First of all, a form handle is a different thing. All forms expose the underlying WIN32 window handle through the this.Handle property, but that's a different matter.
Beside navigating the parent hierarchy (as you pointed out in your original post), the most straight forward way to let a main form method be called from a child form is to pass a this reference to it when the child form is created. Passing this passes a reference to it, not a copy.

I just finished porting my C++ classes over to C# and now I want to document everything. In other words, I want to put the usual /// comments on top of every class and public member. I've started doing it manually, but it seems to me like there ought to be an easier way. I mean, it's a pain to have to write out the opening and closing tags for the summary, params, remarks, etc. So I'm wondering if there's a tool out there that can scan a .cs file, list all the public classes and members in a tree pane (on the left) and allow me to fill in the appropriate doc sections (on the right). This would allow me finish my task sooner, more accurately, and with less typing.
Anyone know of something like this, of should I start thinking about creating one?
Thanks,
Alvaro
