Hello. This is my first post. I'm an online teacher with only a little experience of actually creating web pages so I'd like to ask this question. I was referred here from another forum to an article about creating search engines with a C# spider but the article is quite old so I thought I'd ask here.
I'm trying to duplicate a site, www.acrofiche.com and I believe that the web master is using some code to gather and collect the links rather than manually inputting them into a database. Right now I'm looking to hire a programmer who can do the same thing for me but create an easy-to-use interface so I can do the same thing this site is doing without massive data entry.
Some have suggested that he is using a web crawler and C# to find the document links in an automated fashion. Another person mentioned curl and fsockopen() coupled with some regex code or something like Snoopy.
I'd like to know how this site is created so I know what I need a programmer to create for me since I'm doing this as a side hobby and don't want to get totally ripped off. If anyone has any suggestions, I'd appreciate it.
the site is www.acrofiche.com

I'm sure a lot of people here could help you to write a web crawler; sadly, I'm not one of them. It might be helpful, though, to use View/Source to see what the site is outputting to your browser. That often leads to a wealth of information about the site directory structure, and from there you can often access other information that the designer never meant users to have. Few understand how to fully lock down a site, and you may find good resources such as scripts and server-side code that you can use. Many sites allow FTP access using the username 'email_address' with a password of Guest, and you might be able to glean a lot of information that way. I don't recommend stealing anyone's code, but as a learning tool nothing beats looking at code that actualy works.

Hi ,
I am building a ASP.Net page using c#. I have two tables. In the Employee_details table I have created a reference number for each role. In the master_table I have employee names and the reference numbers from Employee_Details table. Now when I list them in data grid based on a search criteria I should display the name and the role of the employee. How should I do this? We should be able to do this by adding dataset relations.I just forgot that all of sudden. can anyone help me?

i need to convert C++ code into C#. Then the C++ in the form:
number=1
switch(number)
{
case 1:
//do something
number++
case 2:
//dosomething
number++;
case 3:
if ( )
{
//do something
number++;
}
else
{
number= 100;
}
case 4:
............
case 120:
//do something
break;
}
what is the easiest way to convert these code ?
thanks

this will be same in C# but I would like to prefer if statement.

Hi,
you can't fall through from one case to the next (except for empty cases), there must be an explicit change of program flow (break, return, throw, goto, ...)
your C++ code looks like a sequence of operations with a selectable start.
the easiest way IMO to get that done in C# is by putting everything in a for( ; ; ) {} and using a continue after each number++, plus of course providing an exit somehow.
However doing so there will be a performance hit since now the switch dispatching code gets executed over and over.
The ugly but high-performance alternative uses goto and labels; something like:
case 76:
label76:
...
goto label77;
case 77:
label77:
...
goto label78;
This adds two lines per case instead of one, but executes the switch only once.

Why not goto case 77; ?

O great, didn't know that. That will get me going places. Thanks.

Is label needed? Can i do this way:
case 1:
// do something
goto case 2;
case 2:
//do something
goto case 3
.......
thanks!

Why does my skin crawl whenever I see a goto in code  . I guess it is legitimate in this structure but I would never encourage the use of goto's, the potential for disasterous spaghetti dumps is too high.

Could you explain more? thanks

I was merely demonstrating that (by using the C pre-processor) one could use goto without actually seeing the goto keyword. It was a joke.

hello
trying to access oracle database, reading this article from Oracle herself[^]. It illustrates how to configure and retrieve connection but what I need to do is to get an "DbProviderFactory" instance (to align with other db access already in our DAO library)
Any idea how to do this with ODAC? Example:
<br />
public static DbProviderFactory GetConnectionFactory(string strProvider)<br />
{<br />
DbProviderFactory oDbFactory = null;<br />
<br />
if (Providers == null)<br />
{<br />
Providers = new Hashtable();<br />
}<br />
<br />
if (!Providers.ContainsKey(strProvider))<br />
{<br />
if (strProvider.ToUpper() == MYSQL.ToUpper())<br />
{<br />
oDbFactory = new MySql.Data.MySqlClient.MySqlClientFactory();<br />
}<br />
else if (strProvider.ToUpper() == ORACLE.ToUpper())<br />
{<br />
oDbFactory = Oracle.DataAccess.Client.???<br />
}<br />
else<br />
{<br />
oDbFactory = DbProviderFactories.GetFactory(strProvider);<br />
Providers.Add(strProvider, oDbFactory);<br />
}<br />
}<br />
else<br />
{<br />
oDbFactory = (DbProviderFactory)Providers[strProvider];<br />
}<br />
<br />
return oDbFactory;<br />
}<br />
Or should I forget ODAC and use "System.Data.OracleClient.OracleClientFactory"?
<br />
oDbFactory = DbProviderFactories.GetFactory("System.Data.OracleClient..::.OracleClientFactory");<br />
Providers.Add(ORACLE, oDbFactory);<br />
Thanks

 I need to create a class which interfaces with a whole host of other classes. Instead of a Base Class <> Class relationship, I want a Class to interface between many different types of basic classes.
My New Interface Class <> Basic Class (of many types)
This way I have a COMMON interface and structure for my application to work with these basic types.
I think if I use the Base Class <> Class relationship, my application code will be very type specific because of the different functions and data that will be available with the different basic classes.
Is there a good location to read up on this? Any Go-By's? Anybody think this is backwards?
It may be worth mentioning that the different basic classes will all be of similar type, meaning all wil be data and functions. Its not like I am working with graphic, audio and/or function differences.

I have seen tons of people having this issue on google but haven't found a resolution yet. This is my code on getting the byte array from the picture. Then I try to insert it into a database.
But it ALWAYS fails and gives me this: A generic error occurred in GDI+.
byte[] GetPicData()
{
MemoryStream ms = new MemoryStream();
pictureBoxPicture.Image.Save(ms, ImageFormat.Jpeg);
byte[] invPic = ms.ToArray();
ms.Close();
return invPic;
}

In which line you're getting error ?

Here:

try with png format
image.Save(ms, System.Drawing.Imaging.ImageFormat.Png);

Nope.. didn't work... I dug deeper into the breakpoints and see this:
ReadTimeout '((System.IO.Stream)(ms)).ReadTimeout' threw an exception of type 'System.InvalidOperationException' int {System.InvalidOperationException}
base {"Timeouts are not supported on this stream."} System.SystemException {System.InvalidOperationException}
+ WriteTimeout '((System.IO.Stream)(ms)).WriteTimeout' threw an exception of type 'System.InvalidOperationException' int {System.InvalidOperationException}
+ base {"Timeouts are not supported on this stream."} System.SystemException {System.InvalidOperationException}

Do you think there is another way of getting the image from the picture box and saving it to a sql database?
