I created a SnapIn Page for IIS. Its displayed as a tab, when i right click on any of the virtual directories in IIS Manager.
Its called MySettings. Its shown along with other tabs like virtual directory, Documents, Directory Security and so on.
But when trying to view properties of any of the virtual directory IIS Crashes.
The IIS Manager window simply vanishes. (mmc.exe crashes)
I debugged my SnapIn C# code. But it does not even break in initialization of SnapIn Control.
So why does in the first place it crashes, as it does not yet loaded my Page????
Crash is temperamental sometimes it works and sometimes it crashes ?????
But on removing the page from MMC SnapIn List by deleting the registry entry for my Page located at.
HKLM\Software\Microsoft\MMC\SnapIns, IIS manager works perfectly. Now it no longer crashes.
Used debuggers like DrWatson and Debug Diag Tool but could not get any informative data.
Please, anyone can share with me ideas as to how this could be tackled?
Thanks in advance.
Regards.
Pratik.

string[] input = new string[] { "Web", "Images", "Gmail", "C:\\Users\\Amit_Personal\\Documents\\Visual Studio 2008\\Projects\\abc\\abc\\google_image_final.png", "Google Search", "I'm Lucky"};
// Pass the array as a parameter:

{
string fileLoc = @"C:\Users\Amit_Personal\Documents\Visual Studio 2008\Projects\abc\abc\a.htm";
if (File.Exists(fileLoc))
{
using (StreamWriter s = File.AppendText(fileLoc))
{
// StringWriter s = new StringWriter();
s.WriteLine("{0}", "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">");
s.WriteLine("{0}", "<html>");
s.WriteLine("{0}", "<title>Google</title>");
s.WriteLine("{0}", "<link rel=\"stylesheet\" type=\"text/css\" href=\"style.css\">");
s.WriteLine("{0}", "</head>");
s.WriteLine("{0}", "<body>");
s.WriteLine("<h4>{0} ", arr[0]);
s.Write("{0} ", arr[1]);
s.WriteLine("{0} </h4>", arr[2]);
s.WriteLine("<img src=\"{0}\" />",arr[3]);
s.WriteLine("{0}", "</body>");
s.WriteLine("{0}", "</html>");
s.WriteLine("{0}", "");
s.Close();
}
}
Any one Know how to write better code to generate a .html file using C# language..

<img src=\"{3}\" />
</body>
</html>", arr[0], arr[1], arr[2], arr[3]);

You could create a file that is the template and contains the content of the markup. for example:
<html>
<body>
<div> blah blah blah... </div>
<h1>{0}</h1>
<p>
{1}<br />
<a href="{2}">{3}</a>
</p>
</body>
</html>
Then you can read in that file and use that in a single string.Format line to create the files from a template.
public void DesignPage(string TemplateFile, string OutputFile, string[] Contents){
string content = File.ReadAllText(TemplateFile);
content = string.Format(content, Contents);
File.WriteAllText(OutputFile, content);
}
You can also update the file templates without having to recompile, etc.

Here's one other way to do it... Not necessarily the best, but different, and prevents you from forgetting a closing tag.
XDocument doc = new XDocument(
new XDocumentType("HTML", "PUBLIC", "-//W3C//DTD HTML 4.0 Transitional//EN"),
new XElement("html",
new XElement("head",
new XElement("title", "Google"),
new XElement("link",
new XAttribute("rel", "stylesheet"),
new XAttribute("type", "text/css")
)
),
new XElement("body",
new XElement("h4", arr[0] + arr[1] + arr[2]),
new XElement("img",
new XAttribute("src", arr[3])
)
)
)
);
Or something like that...

Similar to what Ian said, but using an XmlDocument:
(Strictly off-the-cuff, not tested, however I did something like this last week to generate an HTML Table in a string)
XmlDocument doc = new XmlDocument() ;
XmlNode nod ;
doc.AppendChild ( doc.CreateElement ( "html" ) ) ;
doc.DocumentElement.AppendChild ( nod = doc.CreateElement ( "head" ) ) ;
nod.AppendChild ( nod = doc.CreateElement ( "title" ) ) ;
nod.InnerText = "Google" ;
doc.DocumentElement.AppendChild ( nod = doc.CreateElement ( "body" ) ) ;
...
doc.WriteTo ( somestream ) ; // To write to a stream
somestring = doc.OuterXml ; // To copy to a string
Also,
amit_ghosh18 wrote: s.WriteLine("{0}", "<html>");
you needn't use the "{0}" to write out a single string:
s.WriteLine ( "html" ) ;
s.WriteLine ( somestring ) ;

Why are you trying to make a fake Google site?
For anything but the most trivial example I second the idea of using a template, and substituting special tokens for items in your data. In my HTTP server[^] the SubstitutingFileReader uses special tokens that look like HTML tags, which makes sense if the template is HTML (or another SGML language).

I am wondering if you can tell me what would be the good items I can drag and drop from the visual studio asp.net 2010 tool kit that would acomplish the following tasks:
1. most of the data would be contained in a datagrid,
2. I would like to have a tab on the top of the webpage where the user can tab to over click the 'next' button to accomplish the following tasks:
*The first tab will:
a. allow the user to have a 'type' ahead feature so they can select what organization they want to work with,
b. there will be a datagrid where the user can check off what suborganizations that are affect,
c. There will be a datepicker so the user can select certain dates, and d. there would be a 'next' button and/or tab on top for the user to go to the next page,
e. On this page, there will be a 'save draft' button. This will not commit the data to the database, but it will save the work entered so far.
f. On this page there will be a restart button. Basically this clear out any data and allow the user to start from the beginning again
*The second tab will:
a. display the data entered on the previous page on the top.
b. there will be alot of rows where the data will be prepopulated, and/or allow the user to enter data.
c. This page will show any errors that the user made.
d. This page will also contain a description of what what kind of data is entered on that row,
e. This page will have a button or tab to update the database.
f. There will be a 'save draft' button. This will not commit the data to the database, but it will save the work entered so far.
g. On this page there will be a restart button. Basically this clear out any data and allow the user to start from the beginning again.
h. The final tab will show summary information of what was just entered.

We don't do homework for you. What possibly could you learn from just copying and pasting an answer from some caring CPians response and turning it in. If that is how you want to get your marks you will seriously need to reconsider your career expectations and brush up on your fries into oil dipping skills because that is what your skills will be worth if you go down this road.
I wasn't, now I am, then I won't be anymore.

This is NOT homework. This is a real job question.
|
|

Then don't do it with the ASP Toolkit. Use jQuery instead - it's much more flexible, and gives you much more control. BTW - you should really have asked this in the ASP.NET forum.

I will askj this question in the asp.net group . Thanks!

Hi everyone, I would like to know how to detect whether .net framework is installed on a user's machine or not on windows platform. I would also like to know how to detect the version of .net framework if installed. I will also be glad to know how to install .net framework on a machine without the user needing to enter next, next, install buttons but rather my application doing the installation. Thanks in advance.
|
|
|
|
|
Look in %SystemDrive%\windows\Microsoft.net\framework
|
|
|
|
|
Thanks, but please how can I do this in code. I want my application to detect it and take a decision. I will appreciate if you can link me to a nice tutorial.

Yes, with classes in the System.IO namespace.

You need to get the value from the registry - it is stored in SOFTWARE\Microsoft\NET Framework Setup\NDP. The result of this value is a string which starts with v, so chop off the v and you have your version. With regard to installing .Net framework without user intervention, the best is to include it with your setup package as a dependancy, to be found in the same location as your installation files.

Thanks Gaylard. But is the registry name the same on all other versions of Windows OS? I have not used vista and windows 7 before so I don't know if they will be the same. A user might be using any of them.
|
|
|
|
|
That's why your app should have the Framework as a dependency. Vista will have .NET 3.5, but not 1.0, Weven will have 4.0.
You can't check the version of .NET in the registry with a .NET application; you'd have to know what version is installed before you can run it. Hence, you'd be writing in an unmanaged language to do some task that the installer already can do. IMHO, a waste of time.

Bear in mind that if no .Net framework is present, no C# app will be able to run. There's no point having an 'is there a framework' app in C#.
However, on any vaguely modern Windows system you can guarantee .Net will be available. .Net 2.0 has been a standard install since around XP SP1, and .Net 1.1 from around 2003 or so. So you could write a checker app in that version reasonably safely.
The framework (particularly a modern version of it like 3.5 or 4.0) is large enough you shouldn't do it 'under the table'. Link it as a dependency for the installer (process varies depending on which installer you're using) and let the user install it.
Remember to use an installer that will work if the .Net you want is not present!

Hello!
I'd like to know how to develop a game??
is that easy?? thanks 
|
|
|
|
|
1. Come up with an idea.
2. Break idea down into small(ish) steps
3. Code game and optionally add resources such as sound effects/graphics.
4. Test game
That's about as low level as you can get with the lack of detail you have presented. For instance, what type of game? A 3D FPS requires a different approach to developing a text-only adventure game. Perhaps, if you broke this down a bit, you might get a better answer.

What's easy for some might be impossible for others. We don't know you, so we can't tell you if it would be easy for you.

Take a look at Microsoft's XNA[^] game studio, you will soon be able to decide whether it's easy or not.
