Search Text In A Scanned Document?
Mar 12, 2010Is it possible to scan a text document to a computer and then programmatically search for text within that document? It doesn't seem likely since the scanned document would be an image but I'm hoping one of the gurus on here might have a solution.

Jun 29, 2010We are going to start accepting resumes online but I need to know if the uploaded files will be virus scanned before I park them into the database. I thought this would be a server thing but the server admin and the security guy both said they didn't know. We already have a firewall and antivirus software, I just want to know how things work with native ASP.Net controls and not a product to try.
View 2 RepliesMaking A WCF Call With AJAX?
Mar 12, 2010Is it required to use a RESTful service to be able to make a ajax call to a wcf service (for example: by using WebInvoke attribute on Operation contracts). Once a service is made RESTful by adding a webHttp binding on the service host, can the host have other endpoints as well? (wsHttp or netTcp). Is it required that the aspNetCompatibilityEnabled be set to true for a service that has webHttp binding (and can this setting coexist for other endpoints). I understand I can use both JQuery and ScriptManager for making WCF calls on the client. Why should I use one over the other?

Making GridView Respond To 2 DropDownLists?
Mar 10, 2010I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.
For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.
i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.

Making A Secure Login Cookie?
Mar 5, 2011I've recently read one of Jeff's articles about XSS and it got me thinking about how to better protect the login cookies in my home cooked authentication system.
[code]....
so one of the questionable things I do is use the UserAgent string. Is there harm in doing this? Or browsers which will change their UserAgent string under normal operation(as in, without being updated)? My goal is basically for if an attacker gets a login cookie, for them to not be able to do anything with it. At the moment, the only info I store in the cookie plain text is the username.

By now I understand there must be a workaround and it is different than simple asp.net

CSV Validation In C# - Making Sure Each Row Has The Same Number Of Commas
Mar 10, 2011I wish to implement a fairly simple CSV checker in my C#/ASP.NET application - my project automatically generates CSV's from GridView's for users, but I want to be able to quickly run through each line and see if they have the same amount of commas, and throw an exception if any differences occur. So far I have this, which does work but there are some issues I'll describe soon:
int? CommaCount = null;
StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);
String Str = null;
//This loops through all the headerrow cells and writes them to the stringbuilder
for (int k = 0; k <= (grd.Columns.Count - 1); k++)
{
sw.Write(grd.HeaderRow.Cells[k].Text + ",");
}
sw.WriteLine(",");
//This loops through all the main rows and writes them to the stringbuilder
for (int i = 0; i <= grd.Rows.Count - 1; i++)
{
StringBuilder RowString = new StringBuilder();
for (int j = 0; j <= grd.Columns.Count - 1; j++)
{
//We'll need to strip meaningless junk such as <br /> and
Str = grd.Rows[i].Cells[j].Text.ToString().Replace("<br />", "");
if (Str == " ")
{
Str = "";
}
Str = """ + Str + """ + ",";
RowString.Append(Str);
sw.Write(Str);
}
sw.WriteLine();
//The below code block ensures that each row contains the same number of commas, which is crucial
int RowCommaCount = CheckChar(RowString.ToString(), ',');
if (CommaCount == null)
{
CommaCount = RowCommaCount;
}
else
{
if (CommaCount!= RowCommaCount)
{
throw new Exception("CSV generated is corrupt - line " + i + " has " + RowCommaCount + " commas when it should have " + CommaCount);
}
}
}
sw.Close();
And my CheckChar method:
protected static int CheckChar(string Input, char CharToCheck)
{
int Counter = 0;
foreach (char StringChar in Input)
{
if (StringChar == CharToCheck)
{
Counter++;
}
}
return Counter;
}
Now my problem is, if a cell in the grid contains a comma, my check char method will still count these as delimiters so will return an error. As you can see in the code, I wrap all the values in " characters to 'escape' them. How simple would it be to ignore commas in values in my method? I assume I'll need to rewrite the method quite a lot.
