WHY DOEST THIS WORK?

RegistryKey RegKeyWrite = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\SystemRestore");
RegKeyWrite.OpenSubKey("DiskPercent");
RegKeyWrite.("DiskPercent",0);
RegKeyWrite.Close();

Maybe you don't have permission to edit the registry?

What is the exception being thrown?

Thank you for your Reply,
No exception is being thrown just trying to set a value to the registry
Guess I'll have to figure out how to give my program permission to set values in the registry

Open regedit.exe
and check if the following reg key exist !

HKLM\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\SystemRestore\\

and if it's not , then replace

OpenSubKey

with

CreateSubKey

P.S
Always use

CreateSubKey

it's try to open the key and if it's not exist then create it .

You've not specified a method. SetValue may be relevant

You should be assigning the result of this invocation to RegKeyWrite

Registry KEYS are the folders you see in RegEdit.

Registry VALUES are the named items in the folders (Keys).

I think you're looking for something more like:

RegistryKey RegKeyWrite = Registry.LocalMachine.OpenSubKey("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\SystemRestore");
RegKeyWrite.SetValue("DiskPercent",0);
RegKeyWrite.Close();

You don't give your "program" permissions to the registry. Your application runs as YOU, or the person or ID that launched it. If you don't have permissions to change that value, you have to use a higher level user account, like an Admin account.

If you're running the code under a normal user account, just about the entire HKEY_LOCAL_MACHINE hive is off-limits. If you're code is not just swallowing the exceptions, your code should have thrown an Access Denied error, or something very similar.

Parse out all the "{" + string + "}" occurences?

Is there a way to iterate through a string of text and find each occurence of a string that contains a substring of "{" + (variable string) + "}" and replace it with a corresponding string defined in a dictionary (of which the key value is the "{" + (variable string) + "}" ??

Yes.

I suppose you'll want a hint as to how! Smile | :)

If the string is formatted such that { and } only occur as a wrapper to a variable name then the easiest way I can think of is to run a regex on it, match all "\{[^\}]\}" and iterate through them.

If not you'll probably have to write a lexer of some kind.

Given that you have the text in the text variable and the replacements in the replacements dictionary:

text = RegEx.Replace(text, @"\{(.+?)\}", m => replacements[m.Value]);

Can anyone see what I'm doing wrong here?
All I want to do is generate a password with htpasswd.exe and it looked
easy enough but it just gets stuck at ReadLine() Confused | :confused:

ProcessStartInfo ps = new ProcessStartInfo();
ps.FileName = Path.Combine(Application.StartupPath, "htpasswd.exe");
ps.Arguments = "-n test";
ps.CreateNoWindow = true;
ps.UseShellExecute = false;
ps.RedirectStandardInput = true;
ps.RedirectStandardOutput = true;
ps.RedirectStandardError = true;

Process proc = new Process();
proc.StartInfo = ps;
proc.Start();

proc.StandardInput.WriteLine("testing");
proc.StandardInput.WriteLine("testing");

string line = proc.StandardOutput.ReadLine();
			
proc.Close();

I know nothing about 'htpasswd', but generally a ReadLine() method expects a carriage return. Did you hit return?

The WriteLine adds a carriage return so that part is ok.
I found what I had missed, the command-prompt needed to
exit before it returned the result.

So adding this before reading the output solved it:

proc.StandardInput.WriteLine("exit");

The exe basically generates md5 hashed passwords IIRC. That can be done in code without needing that exe. Search for MD5 c# and you'll find many results. Here are a couple:

True it generates a sort of md5 hashed passwords, but htpasswd.exe is a part of
Apache webserver and they use a modified version of md5.

Search a sentence in a string

Hi,
My question has two parts:

1) How can I search for a sentence (e.g., Dell Canada) in a string (e.g., I am working in Dell Canada, and I found it...) .

2)The second part is my string is text in a RichTextBox, so I would like to find the TextRange of that selected sentence and apply certain decoration.

thanks.

1) use the IndexOf function for the string...

int startPos = richTextBox.Text.IndexOf("Dell Canada");

2) use SelectionStart and SelectionLength properties of the rich text box the use properties such as SelectionColor, SelectionFont etc. (not tested)...

richTextBox.SelectionStart = startPos;
richTextBox.SelectionLength = "Dell Canada".Length;
richTextBox.SelectionColor = Color.Red;

Easy!... when someone does it for you Hmmm | :|

Hi,

How does one go about, catching the events of a USB card reader...

Currently, when I open notepad and swipe a card, the information on the card is printed automatically in plain text.(Windows installed standard drivers).

How do I go about obtaining the data event, where the data is written? How can I obtain the data written via a simple C# application.

Does anyone understand my question. If vague, plz ask.

Any help or starting point (documentation) would be much appreciated.

Kinds regards,
Higs
