2) What is a class exactly in a dll?

The required is to create a function in vb.net that accept 2 parameter (table_name, fields_list) and return the result in datatable
Now, I am aware of that table_name and fields_list cannot be passed as parameter to the command object using .AddParameter
here is a couple of thoughts, what I would like to know is
1- which function is exposed to sql injection
2- Which function is more safe

I have a question... I recently came across a program called WPE Pro (Winsock Packet Editor Pro). Basically what it does is lets you sniff, edit and send packets intercepted from a process. Thats the key word here PROCESS. From what I can tell WPE uses DLL injection to sniff and inject packets directly into an active socket connection on the target process. What I want to know is how would I go about achieving this? If it isn't possible with the .NET language, is it possible to goto C++ or something?
View 4 RepliesMy question is how best to avoid SQL Injection with the method I am currently using.EDIT (Reasoning): There are many of columns in a number of tables (a number which grows (only) and is maintained elsewhere). I need a method of allowing the user to decide which (predefined) column they want to query (and if necessary apply string functions to). The query itself is far too complex for the user to write themselves, nor do they have access to the db. There are 1000's of users with varying requirements and I need to remain as flexible as possible - I shouldn't have to revisit the code unless the main query needs to change - Also, there is no way of knowing what conditions the user will need to use
View 2 RepliesI have a relatively small app that Im building using vb.net 2.0, and nant. Its a app that calls out to an external exe to produce some output files, then processes those output files afterwards.I have built an interface to the exe, which I have created a stub implementation and the real implementation, what I would like to be able to do is use nant to either create a DEBUG build of the app, which calls the stub implementation, or create a PROD build of the app which will use the correct implementation.

View 5 RepliesI have a web service running that reliably returns a dataset and allows me to provide a list now drop down list box of records returned.I would like to capture the users selection from the DDL and call another web service to return detailed information regarding the selection. Hence a WHERE stmt in the query of the web service. I am of course worried about SQL injection. But I would ike to at least get the SQL stmt working.The selection is a string field type, and looks like this,[code]Everything works for other web services if I remove the query with the WHERE clause.

I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.
Code:
''' <summary>
''' Exports data from a datatable to excel.
''' </summary>

Where in Visual Basic 2008 Express Edition Software program do you specify a specific installation directory for a program?
c:Program Filesfinished program
I want to publish my program to try it out on another system and I want to ensure its installed in the directory structure I want.
i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
