There are tons of articles out on the web, most wih code samples! All you have to do is Google "steganography".
This is for a univeristy project? Didn't they teach you how to do research, oh, back in high school? You better learn very fast because that skill is what is going to keep you in a job.

im using microsoft visual c# express and its database.
through my c# program i wanted to retrieve a folder path from the database to select files.but im getting this error.please help.
i have created a column 'folder_path nvarchar(50)'
my folder path is : @"f:/pick_up"
if i put folder path as 'comp' it reads.i guess the error has something to do with special characters @,/ and ".
reply asap.thank you.

Is that what you have stored in the database? If so, you need to remove the @ sign.

stored it as '@"f:/pick_up"'..but if i remove it.d the path is not complete.
i also tried to store without '@' in a string variable s(where s= "f:/pick_up") and then did s="@" +s;
even then i get the error.
in fact when i directly put d path in
string[]folderPath=Directory.GetFiles(@"f:/pick_up","*.jpg",SearchOption.AllDirectories);
it runs
but if d path is replaced with s it gives error

that is a big no no.
If
string myString=@"f:/pick_up";
Console.WriteLine(myString);
then myString will hold exactly 10 characters, starting with f and ending with p.
It's those 10 characters you would type after "dir" in a command window to display the content of the folder. The special characters @ and " are NOT part of the string, they only exist in your source code to tell the compiler what the value of myString really has to be.
And it is exactly those 10 characters you should store in your database.
I suggest you open an introductory book to C# and start studying the very first chapters ASAP.

Won't work, @ tells the compiler it doesn't need to take in account the escape character. ('\') it is not part of the string itself.
Store the variable as "f:\\pick_up\\" or use @"f:\pick_up\" which is the same. It will be saved as "f:\pick_up\" and when you get it out it will come out as "f:\\pick_up\\" which is what you need.
If it still shouldn't work, post the error message and check the debug information.

thank you so much V,'f:\\pick_up\\' worked.
but not @"f:\pick_up\".y so?
also when i explicitly put d path in d command string[] folderPath = Directory.GetFiles(@"f:/pick_up", "*.jpg", SearchOption.AllDirectories);it works.
but when i retrieve d same string saved in d databse i get d error.
im new to c#.

When you retrieve it from the database, the string contains @. What you are issuing as a command is Directory.GetFiles("@\"f:\pick_up\"", "*.jpg");. That is why I told you to remove the @ earlier. Perhaps you might listen next time.

Don't guess. Paste the entire Exception.ToString here, the error-message will point where the problem is.

Good day
I am using Visual Studio 2010 to develop a Windows app. I am busy with a module where the user can specify setting for days of the week, for example Mondays the lunch duration is 1 hour, Tuesday it is 30 minutes, and so on.
I want to display the days of the week (Sunday, Monday, …) in a ComboBox so that the user can select a day.
The DisplayMember must be the name, e.g Monday
The ValueMember must be the ordinal number of the day in the DayOfWeek enum, e.g. 1
How do I populate the ComboBox using the DayOfWeek enumerator?
I tried:
private void Form1_Load(object sender, EventArgs e)
{
for (int j = 0; j < 7; j++)
{
comboDay.Items.Add((DayOfWeek)j);
}
}
private void comboDay_SelectedIndexChanged(object sender, EventArgs e)
{
MessageBox.Show("Selected Day = " + comboDay.SelectedValue);
}
This shows the DayOfWeek names in the combobox, but the SelectedValue is always null.
Any suggestions on better ways of doing this?
Thanks.

Use SelectedItem instead of SelectedValue.

|

Thanks
I feel a fool for not thinking of that.
Regards.

It's always the way. As soon as someone else looks at it, you see it.

public static List LI = new List();
|
|
|

Unless you've created your own class called List, you are missing the generics part. You should declare it like this (assuming it's a list of ints for instance):
public static List<int> LI = new List<int>(); A few points:
1. Your question should not be the header. Make it part of the post instead.
2. Calling a list LI isn't a great idea. You should always look to use meaningful names in your code.
3. Use <pre> </pre> around code samples. The code tool in the editor toolbar will help you with this.

PLSSS DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.
And while you are at it, drop the txtspk as well...

When using VKontakte API method wall.get or friends.get client receives a response just once. When increasing for example the offset parameter such requests do not pass. An error is returned InnerException = {"The request was aborted: Could not create SSL / TLS secure channel."}. What is the possible reason?
|

|

You have posted a fair bit here about this API. I would suggest that you would be better off seeking answers from the support forums at vk.com. You also never seem to show code. Here's a hint, we can't read minds so we don't know what's wrong with your code.
