I am encrypting a file with this code.
[Code]....
Error #1 Encrypt works but decrypt does not. This is b/c the file extensions in TextBox1.Text is .txt and it is looking for .enc Error #2 If I enter in the file.enc the file will be decrypted but it will have the file extensions .dec. How can I copy the extensions (.txt) and replace the .dec after it was decrypted.
In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?

I am trying to programmatically log error codes from any exceptions thrown on a PDA using CF3.5. Does anyone know how to get the most precise code for an error?
I've been looking at getting the HResult value of the thrown exception (which I can do), but this doesn't seem specific enough.

View 5 Repliesi have been trying to figure out auth system and after tons of researching and asking questions, I found a tutorial that "almost" fits my needs. This is what the code does:Basically a new form is created with a textbox and a connect button on it. When the program is loaded, the textbox has your hardware ID on it (also known has HWID). Then it looks for that HWID on a text file of the link given [URL] in this case as an example. If that HWID is found on that text file, then it leads you to form2 which is an actual program and if not, form1 closes meaning you have no access to anything at all. A basic authentication system and here is the code for it:
Imports System.IO
Imports System.Management

View 11 RepliesIm going to get started.Im setting up an hwid login for my vb.net program,
To be safe, im not directly connecting to my db from the program, because if it was cracked, my db info is leaked,so i want it running through php,
this is my current php code
<?php
$con = mysql_connect("localhost","username","password");
if (!$con)
{
die('Could not connect: ' . mysql_error());
[Code]...
of course, i have removed my db info, but im getting this error Parse error: syntax error, unexpected T_VARIABLE in db.php on line 10
I cant seem to find what the problem is, what i want to do is have the program submit the hwid like this site.com/db.php?hwid=hwid here and have it echo the name in the row of the hwid submitted.
1) How do I lock my application to user's HWID?I want it to work this way: when a certain user opens my app, it automatically scans for his hardware ID and lock the application to it so noone other than the user can use the app.
2) I'm planning to use SmartAssembly trial version to obfuscate my code, will this affect my application in any way? Like, crashing?

Just completed a program, and tested it. It works, and does exactly what its supposed to do, but I continue to get this error: Cannot Write to a closed TextWriter.The code I'm using is below, but the issue here which I'm guessing would be that in my If statement.[code]'Goes on to create a bunch of tabled XML text.I have this code copied throughout each If Then loop. Basically If the text box is blank then the program will close the table and stop writing.I know the problem most probably lies in that its reading that its trying to close the table or stop writing, but the program forces it to continue.
