Is This A Secure Method Of Providing Service For Database Applications
May 10, 2012
WinFormsApp Login passes information to .php (server based) Login (provided credentials are correct) to DB to retrieve Decryption Key. WinFormsApp then uses Decryption key on Hardcoded encrypted connection string and renders application usable.This would then eliminate the necessity to encrypt/decrypt a connection string at runtime, virtually rendering any unauthorized person with a useless software.

I don't want my programs to be cracked. I have this simple authorization system that prompts my users to enter their forum credentials (I have a forum and the users must be registered members to use the programs).So I made a php script that will take in 3 strings sent in by my applications and it will check against the database if that user exists and is of the proper group and it will display a message on the page and my application then looks for the response in the page source which says if this particular user is allowed to use the program or not.

I am going to be creating a web service that will be passing confidential information across the network.
What would be the best way to secure the web service? how do I know if the application requesting the information is who it says it is, and it's not another application that is using another's user name and password?

I am programming a service for a company that will log valuable performance data on machines that they lease out to other companies. It is critical for them that this information is as safe as possible and that it can only be read by us (a program created by us that is). I already made a trippledes encryptor that works fine but i still have the issue that a person can delete or move or corrupt the file if he somehow manages to get out of the operation software and gain acces to it.So my question is: Can i lockdown a file and make it as good as impossible to change the file or delete it other then by being the admin or the program that is generating them?

I recently made a small app for a friend and then made it a public app, in doing so I forgot that it connects to my MS SQL DB and checks for values. Someone used Red Gate .Net Reflector to get my password and destroy it all. I've contacted their ISP and they are looking into it, apparently this person has a static ip with them.So this is a lesson learned at a heavy price for me. How can I prevent this from happening again? How can I get away from the unsafe connection string they were able to use?

I have a asp.net web application with jquery controls. I have a datagrid that will display data from a database table and created a WCF Service to access the db and return the data. I want to be able to call the WCF service from this application which is on a different server and have the xml data returned, converted to json format to be used in the datagrid which is a jquery widget. I have tested the web service and it works fine. Should I call the web service from the javascript function within the xml or create a .net method behind that calls the service and then does the conversion? From these how would I get started?

I have written up troubleshooting documents for my project and would like them included in my program. I remember in VB6 there was a very easy way to do this with a control, where it already has the help document tree set up on the left and you just set it to point to certain files.
Does something like this exist for .NET? I am aware of the HelpProvider control but as far as I know this just puts in tooltips and opens documents on a button press?

Is it possible to somehow invoke foo("SomeAwesomeString") from VBScript directly (i.e., without it having to launch an additional process)?
The use case is this: I am trying to write an 'extension' application for hMailServer (hMS), but hMS can only invoke VBscript scripts when an event happened. I can have the VBscript launch an .exe every time the event happened, but the processing involve opening and closing a connection to a back-end database. So, every invocation is very expensive. I had been thinking that I can reduce the expense by having a Service to maintain the connection (i.e., opening it once and re-open it if the connection closed). Plus by implementing the processing as background worker threads will result in a non-blocking processing + less process-starting overhead.

How do you provide an image to the program, so the program finds that image on the screen and tells its coordinates. So if I was to provide an image of the start button, the program would tell the coordinates like (2,1000) or something similar.

Consider the following :
Dim Length1 As Double = (10* 12) + 5
Dim SqFt1 As Double = 0.0
Dim length2 As Double = Length1 / 12.0
Dim tape As Double = CType(210.0, Double)
'Length2 at this point has a value = 10.41666
SqFt1 = CType(length2 * tape, Double)

I have a Deployment project which creates an MSI setup file to install a service. (VB .NET) I have a reference to another project which is a win form application and has a setup form which takes the user name, password and some other settings information which will be used by a service. It has "Finish" and "Cancel" buttons. I am creating a new instance of this form on Sub New() of the ProjectInstaller Class, so user can input information, click Finish and installation completes. The service is then automatically started. Now, when I click Cancel on the settings form, I am not able to exit out and halt the installation process. Instead it installs the service !! How can I use the Rollback or Uninstall methods to do the task? I was trying this -
On cancel_click, set boolean var cacelStatus = True
On Sub New() method of ProjectInstaller class, I am checking - If true - uninstall, else - install
How can I achieve this?

I'm a first time visitor and poster, but I'm definitly going to stick around. I'm running an old version of Visual Studio .Net Academic 2002 and the .Net framework 2.0. I'm stuck on an issue regarding the deployment of a few programs I've thrown together. They all work fine on my development machine, but the problem they all use SQL Server databases, and I can't find any specific help on deploying a windows application with a database on a machine that isn't set up basically just like my development machine.
I know that I need the .net runtime bootstrapper on the target machine, so I can run basic programs that dont use SQL databases. That's no problem. But what about programs that make heavy use of databases? How does one go about deploying it on target machines? Is there a SQL server bootstrapper?
