• Visual C# Password?

  Is it possible to password protect a program you can store a hash of the password instead of the actual password.  Then your program compares the hashes instead of comparing passwords. It works like this: 1) create a hash of your password. 2) When user enters a password, hash it and compare to your hash.   1)- Code to generate hash (separate program). using System; using System.Web.Security;   // add reference to System.Web class Class1 { [STAThread] static void Main( string [] args) {  // generate has in separate program. Console.WriteLine(FormsAuthentication.HashPasswordForStoringInConfigFile("passwd!@", "sha1")); //the h ...Show All

• Visual C# Finding Drivers

  I want to write a program that finds the drivers that you are using on your computer and copies them to a zip folder for storage.  I am thinking I could enumerate through the registry under the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\ and find all of the names with InfPath in them and find the name of the inf file.  Correct me if I am wrong then try to find the inf file in the windows\system32 folder.  Then search the inf file for the full path of the driver.  I could then copy the file into a zip.  So now for my questions, is this possible programitacally   Second, would this be an effective way or is there an easier approach   Third, I don't know how to do all of this and was ...Show All

• Visual C# Thread Message Suggestions

  I have a question. In my C++ days, I had straight C++ threads using thread messages to act very similiar to MFC UI threads to process messages even though they weren't connected to a UI. The Win32 calls included ::CreateThread(), ::PostThreadMessage(), ::GetMessage() to simulate the behavior of just dropping a message into a thread queue to process the message. Now that I am in C## land, I can't seem to find any documentation about thread messages which tells me that I am looking at the problem incorrectly meaning C## does things differently. Suggestion Having the thread message queus for free is quite some time saver. Doing that in C# would take some work: create a Queue (maybe Generic) for all types of ...Show All

• Windows Forms dynamic control layout

  Hi All, Is there a way we could make the TableLayoutPanel behave similar to an excel sheet, where we have a list of controls added (vertically), and it should also be possible to add control between rows i.e. insert a new row between two rows and push all controls (or rows) under it to move down I'm try to have this done dynamically, where the user would select some option from a listbox and based on that value some controls would be created below it....

• .NET Development [system.net.mail.smtpclient]: Does anyone know of a *real* way to validate a successful email send?

  I've looked in the intellisense, online .Net docs, and on here... long story short i can send email but want to read the status code of those emails... preferably the SMTP status code. so far the only close solution to verifying a successful send is using the mailmsg.deliverynotificationoptions.. but that's hardly a solution... that is based on a return email for delivery notification... for catching errors it's easy enough... just try/catch it and grab the status code there... but i'm looking for something on the success/delay (delays can still be successful) status code as well. I'm looking for a status code (250 OK, 500 ERR, etc), not some return email - a *real* way. any help would be appreciated, -Scott ...Show All
