This is what I have found out so far: it seems that what you are working with the forms resource folder, and you delete a resource file, I get a message saying that the designer might become unstable. as soon as I delete a resource and I get the warning message and I say Ok, then the menu items disappear and some other random items disappear. The solution to avoid this problem is instead of deleting, one should exclude instead.

Ive been developing a app that uses a sql compact database (3.5).
when the app installs the database connection path is designed to be dynamic (ie i dont know if there local drive will be c?)
so ive written the follwing (feel free to advise if there is a better way to do this)
namespace SomeNameSpace.DataAccess.Help.SQLCommands
{
internal class ConnectionCommand
{
internal class GetConnectionCommand()
{
internal const string LiveDatabase()
{
private readonly static string xDataSourceAccess = "Data Source=" + System.Windows.Forms.Application.StartupPath + "\\Data\\database.sdf;Password=password1;Persist Security Info=True";
return xDataSourceAccess;
}
}
}
}
but im concerned about have the password in free text, any example of how i can improve this?
thanks

You mean you're concerned that it's plaintext?
Well don't worry, it's impossible to actually encrypt it. You can obfuscate it (possibly with encryption, but the key you use for that will have to be stored, unless you encrypt the key in which case you have a new key, and in the end you will always have an unencrypted key) but keep in mind that obfuscating it will tell any hacker who just accidentally comes across it that it is something that you wanted to hide and thus must be something important.
So, my advice would be to use the "hide in plain sight" trick - just put it in the AppSettings somewhere, not encrypted, but in separate parts (not the whole string, but only parts, like "password1" or maybe "pass" and "word1" somewhere else to make it look less like a password)
Doing any encryption on it will only make it stand out, and it will never make it impossible to get the password unless even your app itself can not get the password either (which is pretty lame)

..That's just bad advice.

Not really, there's nothing better you can do..
If you "encrypt" it, the "encrypted" data will stand out like a fire in the night and coupled with the fact that it's impossible to actually encrypt it the situation would just be worse than if it weren't encrypted (and people would just ignore the data unless they were actively trying to hack it)
|
|
|
|
|
Of course the password would have to be something that doesn't look like a password, but that's a small price to pay..
|
|
|
|
|
Encrypt the password in the settings file - as Harold said you can't stop a REALLY determined hacker, but then you aren't interested in a really determined hacker, your customers are only mildly curious about the data in THEIR database and an encrypted password will do 2 things. Supply a reasonable level of security against the power user and assure your customer that you take security seriously.
Remember the customer is, well your customer and it is his perceptions you need to cater for.
Never underestimate the power of human stupidity

Hi i am new to OOP and c# , Im building a program that reads settings form a .cfg file .
I have managed to import the entrire cfg file into an array using string .split
onst string fName = @"Settings.cfg";
string[] lines = File.ReadAllLines(fName);
List<string> fields = new List<string>();
foreach (string s in lines)
{
if (s == "" || s.StartsWith(" ") || s.StartsWith("/"))
{
continue;
}
fields.AddRange(s.Split(new char[] { '=' }));
}
Settings = fields.ToArray();
However this also adds the setting name to the array which is not needed , is there any way to modify the code so only values to the right of the = get added to the array ?
Thanks

you can use Substring method instead of Split method.
find the index of '=' character using IndexOf method and then pass this index + 1 as the parameter of Substring method.
|
|
|
|
|
Two things occur to me.
The first, to allow you to carry on using the same design that you have:
if (s == "" || s.StartsWith(" ") || s.StartsWith("/"))
{
continue;
}
fields.Add(s.Split(new char[] { '=' }[1])); <===== you might have to add a ToString(), or cast to a string
The second would be to use a Dictionary, rather than a List for fields. This would allow you to keep both parts; the setting name as the key and the setting value as the er.... value.

If the value contains an equal sign, then also use the overload of Split that limits the number of strings returned.
|
|
|
|
|
If your cfg file is set out like:
Name=SK
FavWord=Delicious
So you only have one item per line, you should just be able to add the second element of the array:
foreach (string s in lines)
{
if (s == "" || s.StartsWith(" ") || s.StartsWith("/"))
{
continue;
}
string[] parts = s.Split(new char[] { '=' });
fields.Add(parts[1]);
}
Also, it might be worth your while to check out the Dictionary class, which may work out better for you. With a dictionary you can add an item like this:
myDict.Add("Name", "SK");
string m_name = myDict["Name"];
Handy stuff.

sbrHTML.Append(";.premium { mso-number-format:$\\#\\,\\#\\#0\\.00;} .ogDate {mso-ignore:padding;mso-generic-font-family:auto;mso-font-charset ;mso-number-format:yyyy-MM-dd;mso-background-source:auto;mso-pattern:auto;} ;");
then i am applying style for audit like the following
sbrHTML.Append(";" + (sqlDatareader.IsDBNull(columnIndex) ? "" : sqlDatareader["AUDIT_DATE"].ToString() + ";")); ogDate
For the above stmt i am able to get only this formate "2008-07-08" but i need to include time also.
Could any one help me in mso-number-formate: to get date formate like "2008-07-08 20:24:14"
thanks,
eswar.

In Excel you can format the cell with a Custom format of yyyy-mm-dd hh:mm:ss or as a Date with International (ISO) locale.
How you'd set that via C# I don't know.
|
|
|
|
|
You can use DateTime.ToString. Pass the format you want, for example yyyy-MM-dd hh:mm:ss. You'd have to hack through the documentation for more format strings information

Hi,
I have 2 forms and i'm trying to send string from Form1 to Form2,
I don't want to do it by using a constructor.
I want to do it with property.

So, create a public property in the Form2 and set it when you create and instance of Form2.

Hell c# gurus , I am new to C# and im have a general question about c#
I have a datagrid , a text file full of urls and a string . Now the string is actuly the live data output of a program .
Ive already have written the code to import the entire text file into my data grid , What i would like to do is while importing the urls in the foreach loop check the value of s and see if it occurs anywhere in the live output string the value of the string t changes to pending .
Is there anyway to do this ?
const string fName = @"1.txt";
string[] lines = File.ReadAllLines(fName);
List<string> fields = new List<string>();
foreach (string s in lines)
{
int n = dataGridView1.Rows.Add();
dataGridView1.Rows[n].Cells[0].Value = s;
dataGridView1.Rows[n].Cells[1].Value = t;
}
