View 1 RepliesI came to a company that already has a fully grown project... but coders that worked here before me didn't follow conventions and didn't use parametrized SQL queries... as a result there is over 1000 places in a very huge project that can possibly be vulnerable to SQL injection...
I need to find a solution that will automatically detect if there is an SQL injection in the code. So, for example there is a form which allows user to enter comments regarding a product, which will be sent to database on submit... how can we make sure that a user didn't enter a harmfull query instead of a normal text?
Is there any advanced code/regular expression/magic that can detect if this text contains a piece of SQL query instead of normal harmless text? I will accept any links, pieces of code in any language or even commercial software that will do that for me.
How do you pick a random piece of text from a text file in this manner....

I need to pick a random answer, not including the question. let it be the simplest solution. I am only a beginner.
Im trying to parse a log file and display the data in a textbox.The log is forever changing so it will have to be some kind of a loop.I only want the new data to be added to the textbox after the application is running, not the contents already in the log file.

View 5 Replies[code]The two parts I've coloured red change, I need to grab the first part which is the link but I'm not sure how to do this. I've used regex before and it doesn't look possible to use it on this on this, there's about 25 of these in the source.
View 11 RepliesI need my application to do some fairly simple C-style curly brace text parsing. The text style is similar to C or C# in that it uses curly braces to define blocks of code.[code]As you can see it also uses C-style comments (//) and can (actually always will) use nested blocks, but only up to one level of nesting is allowed. As you can also see, the code does not have to be formatted neatly. There can be spaces before any opening or closing brace and it will still be valid.The text however is not similar to C or C# in a few ways:
- it does not need a semicolon ; after each 'statement' (abc, def)
- the block names will always consists of one single word except for the possibility of comments behind that word.
- the event names may contain more words
- the block and event names do not end in parentheses ()
I am telling you this because I have a C and C# parser which I can use (it came with the text editor control I am using) but it does not recognize the language I need as valid C or C#, because the block names do not end in parentheses, and the commands are not ended by semicolons. Therefore it keeps doing things wrong (it should automatically outline the text, auto indent it, smart format it etc) because it is expecting C syntax exactly, and it sees my language as loads of syntax errors (missing semicolons etc).So, I need a way to parse the language manually, and it needs to be pretty fast too. Some of the things I need include:
- Getting an entire block (including nested blocks) just from the block name (identifier?).
- Getting all block names (nearly had this working with the help you guys gave me but not completely there yet).
- Getting all event names in a specified block.
- Getting an entire block (or just the block name) just from the current cursor position (if the cursor position is somewhere in block2 I should be able to identify that and return 'block2').
- Probably more...
Then I thought, wait a minute, this C-style language is probably the most used language style, so there should be LOADS of examples online... So I started googling but did not find many relevant things.Is there anyone who has any knowledge about simple language parsers? Anyone who can help me do the things I wrote above..? I realize I am asking for a lot, but the language is pretty easy and I cannot imagine that it is extremely hard to parse it quickly. I also don't require any syntax error checking; all I need are the few things above (mainly retrieving the block names and event names).
I'm stuck on an issue I think is actually pretty simple but I just can't get it sorted.
I have a string containing (a lot of) text, and in that text there are dates. Like 2/28/2010 or 11/12/2007 or whatever.There are multiple dates in that text.
How do I get the dates from that piece of text into another string so I can put the dates into textboxes?

I would like to search a webpage for a value in the left column of a table, then pull the value from the right column as my result. In a Visual Basic Forms Application.
the data is listed in a table, for example...
abc 123

ghi 345
jkl 456
and if i just want the value of ghi ( I know "ghi", but i want the goal of the code to find the "345")

I have a datagrid view with 3 columns and variable rows. I have many rows so it is tough to know what is where so, the first row consists of names.I have a textbox in which I type in a name and hit a button. Doing this, I want the location of the that cell in terms of row.no and column.no.
Extended : for the adjacent ones just add +1, +2 etc to the column number right ?
I am trying to successfully multithread a piece of software I have been working on. I have an array of threads 'gen' already working, calling to a method taking a single integer as a parameter (done via typecasting).Now in this thread, when the function gets processed (for each thread a roughly 500 iteration while loop) the index seems to be getting mixed up. As far as I can tell, my threads are messing with eachother and warping values. Now this is happening in locally declared variables inside this function, not global variables.It may be useful to know that I am using a WebRequest via a call to another method. Don't know if that makes a difference or not.

I'm just curious as to how some software programs that I see out there have the ability to extract links & text from thousands of web pages at an extremely high and fast rate. Has anyone here, ever created a link or text extracting program the has the ability to parse many webpages and return data into a textbox? I know how to extract links via the webbrowser control, but it doesn't seem to parse/extract data at a very high & fast rate like many email, link & text extracting programs that I see out there.

I'm looking at implementing a piece of software I've created into a new environment. It is currently accessed via network share by users who have full administrative permissions on their user accounts. These same users will have their accounts locked down excessively. I am wanting to consider now before any changes have been made, any code changes I will need to make as my application makes use of a lot of features that admin users take for granted such as registry editing. My program is running through the .net 3.5 framework and is being accessed on XP machines.

in vb, you can use text which is in textbox instead of numerical expressions. I mean, if I write 50 in textbox1 and also I can write like that code:
Dim result As Double = TextBox1.Text + 0.4
as you see, I didnt convert any type but it works in vb.net
But I want to learn what are disadvantages of this using?

I am attempting to parse multiple lines of text from a text file using regexpressions. I am using vb.net with visual studio 2008. At the moment I am filling my datatable with the text file information and am able to return each line of text and parse the first set of numbers that I am attempting to break up. I have multiple string with varying lengths of character lengths and numeric lengths however the delimiters are sometimes different. Sometimes will be whitespace and sometimes will be whitespace and chars. But is always 2 spaces. Here is my code:

I have a rich text box full of encrypted data split by ";" and I have
Dim Pass, Data, Game1, Game2, Key1, Key2 As String
Dim PassEnd, Game1End, Game2End, Key1End, Key2End As Integer
Data = showencrypt.Text
PassEnd = InStr(showencrypt.Text, ";")
[code]....
Pass gets decrypted ok, and Game1 gets decrypted ok. Key1,Game2,Key2 are all the same as Game1 though. Is there something I am missing? Why is it setting all of them the same? I've tried settings the Start of the InStr's at the previous End but it doesn't work.
I'm toying with an idea that would require me to parse a text file that contains a SQL statement. (i.e. Select * From Customers) I would like to be able to programmatically via Visual Basic identify key words, table names, comment lines, etc.So, how do compilers handle such a task? How does a SQL database handle such a task? All of the parsing tools are for CSV files with some sort of consistent delimiter. I'm wondering if I need to read the file one character at a time and then do some sort of comparison.
