And? You STILL don't know how to ask a question. That one doesn't provide anywhere near enough detail.
I have no idea what you're talking about when you said "identity without a hyphen".

Look at the stack trace. It's telling you that the code blew up in your WaterMarking.ImageDoc.ImageDoc_Load method. You're doing something with a path, "C:\tmp", that isn't allowed by the user running the code.
|
|
|
|
|
To add to what Dave says, you should use Path.GetTempPath[^] to get the location of the temporary folder: "C:\tmp" would fail miserably on my pc, where the temp folder is on the "D:" drive!

I need to ALTER merge sort algorithm to get length of an array and enter strings then sort them alphabetically ... Im stuck on the sort...my code atm.... The code doesnt sort as I know that it isnt comparing the strings it works in the original form with numbers already hard coded as in ALL the things i have seen and i understand the int sorting but as i said earlier i want it to accept inputted strings and compare them alphabetically and am finding no guidance on how this is to be achieved apart from the compareTo method...so when this runs i get the strings inputed on the txtoutput UNSorted but cant seem to alter the mergeSort to sort the entered strings alphabetically
private void btnExecute_Click(object sender, EventArgs e)
{
int length = Int32.Parse(Microsoft.VisualBasic.Interaction.InputBox("Enter a Number for how many Names to Sort :"));
string[] nameArray = new string[length];
foreach (string n in nameArray)
{
string name = Microsoft.VisualBasic.Interaction.InputBox("Enter " + length + " Names to add to Array:");
length = length - 1;
txtOutput.Text += name + "\r\n";
}
txtOutput.Text += nameArray.Length + "Names Added to List Unsorted ";
txtOutput.Text += "Sorted List : " + "\r\n";
mergeSort(nameArray, 0, nameArray.Length - 1);
foreach (string i in nameArray)
{
txtOutput.Text += i +"\t";
}
public void mergeSort(string[] nameArray, int lower, int upper)
{
int middle;
if (upper == lower)
return;
else
{
middle = (lower + upper) / 2;
mergeSort(nameArray, lower, middle);
mergeSort(nameArray, middle + 1, upper);
Merge(nameArray, lower, middle + 1, upper);
}
}
public void Merge(string[] nameArray, int lower, int middle, int upper)
{
string[] temp = new string[nameArray.Length];
int lowEnd = middle - 1;
int low = lower;
int n = upper - lower + 1;
while ((lower <= lowEnd) && (middle <= upper))
{
if ((nameArray[lower]).CompareTo(nameArray[middle])<= 0)
{
temp[low] = nameArray[lower];
low++;
lower++;
}
else
{
temp[low] = nameArray[middle];
low++;
middle++;
}
}
while (lower <= lowEnd)
{
temp[low] = nameArray[lower];
low++;
lower++;
}
while (middle <= upper)
{
temp[low] = nameArray[middle];
low++;
middle++;
}
for (int i = 0; i < n; i++)
{
nameArray[upper] = temp[upper];
upper--;
}
}

You cannot use foreach at this point, since your array does not contain any strings. And even if it did, you never add them to the array. You should use the number as a loop counter and enter a string at each offset. Although you could probably improve this by using a collection class rather than an array.
|
|
|
|
|
Why? Sorting is already implemented in several places (for example in List<T> and Array, both are unstable introsorts)
|
|
|
|
|
The first thing you're going to have to do is actually split the strings out that you received in the InputBox. There's a massive hint there that you have to use string.Split to split the input[^] and return an array of characters.

Please, don't post code like that:
public void Merge(string[] nameArray, int lower, int middle, int upper)
{
string[] temp = new string[nameArray.Length];
int lowEnd = middle - 1;
int low = lower;
int n = upper - lower + 1;
while ((lower <= lowEnd) && (middle <= upper))
{
if ((nameArray[lower]).CompareTo(nameArray[middle])<= 0)
{
temp[low] = nameArray[lower];
low++;
lower++;
}
else
{
temp[low] = nameArray[middle];
low++;
middle++;
}
}
while (lower <= lowEnd)
{
temp[low] = nameArray[lower];
low++;
lower++;
}
while (middle <= upper)
{
temp[low] = nameArray[middle];
low++;
middle++;
}
for (int i = 0; i < n; i++)
{
nameArray[upper] = temp[upper];
upper--;
}
}
It makes it very hard to read!
Instead, use the "code" button above the text box to insert the <pre> tags which preserve formatting:
public void Merge(string[] nameArray, int lower, int middle, int upper)
{
string[] temp = new string[nameArray.Length];
int lowEnd = middle - 1;
int low = lower;
int n = upper - lower + 1;
while ((lower <= lowEnd) && (middle <= upper))
{
if ((nameArray[lower]).CompareTo(nameArray[middle])<= 0)
{
temp[low] = nameArray[lower];
low++;
lower++;
}
else
{
temp[low] = nameArray[middle];
low++;
middle++;
}
}
while (lower <= lowEnd)
{
temp[low] = nameArray[lower];
low++;
lower++;
}
while (middle <= upper)
{
temp[low] = nameArray[middle];
low++;
middle++;
}
for (int i = 0; i < n; i++)
{
nameArray[upper] = temp[upper];
upper--;
}
}
Second, a problem report like "Im stuck on the sort...my code atm.... Help its driving me loopy" tells us nothing at all about the problem you are having.
Tell us what it does that you didn't expect, or doesn't do that you did!
Tell us what data you use to test it, and what you expect to get as a result. Then show us what you do get!
The better the information you give us (and remember that we can't see your screen, access your HDD, or read your mind) the better we can help you to fix the problem.

thankyou I apologize I am new to this but i did say I am having trouble ALTERING the code to accept strings rather than ints
as the original code has hard coded numbers the question needs to get 1 input box to give the array length which is working but the strings that are entered on the second input box i can not find where to compare the entered text to and sort them alphabetically on the go ....
|
|
|
|
|
That doesn't tell us anything about what kind of problem you are having doing it.
Since you wrote the code, we can safely assume that you fully understand it, but we don't know what part of your code you don't know to change! Or what is making it difficult for you.
Seriously, we can't see your screen - we only get what you give us to work with. So teh better the info you give us, the better we can answer...

I use to mark Dictionary of Cell type (of the GridView of DevExpress), for example, declare the type of row, I declared thus:
[code]
Dictionary<datarow, color=""> colors = new Dictionary<datarow, color="">();
[/code]
code above the type of row, declaration row is: DataRow, I want to replace the type DataRow is Cell type of the DevExpress GridView What is keyword in C# ?
|
|
|
|
|
What?? Your question made no sense at all.
How does a Dictionary relate to a GridView? What does a DataRow have to do with any of this?
|
|
|
|
|
my obstacles and express language, English is not my main language
In C # it allows type declarations corresponding row and column types as follows:
Dictionary<DataRow, Color> colors = new Dictionary<DataRow, Color>();
Dictionary<DataColumn, Color> colors = new Dictionary<DataColumn, Color>();
but I want to declare the type of cell that is the type of grid, I don't found place.
Dictionary<???, Color> colors = new Dictionary<???, Color>();
|
|
|
|
|
I have no idea what you're doing because the code doesn't make any sense to me. Why would you have an entire DataRow or Column as a key in a dictionary??
|
|
|
|
|
because I do not want to use the loop (for or while) to access grid
|
|
|
|
|
Very, very weird. It's like you're trying to treat the grid like it was an Excel sheet. These data grids are not designed for that.
Individual cells do not have a data type. The type is determine by the type of the column.

saving keypairs , public keys to file, using these keys to encrypt decrypt a file?

Saving keypairs? Which keypairs?
Which type of file are you using?

Thanks for your reply. I figured this out
KeyPair keyPair = PublicKeyBox.GenerateKeyPair();
byte[] privateKey = keyPair.PrivateKey;
byte[] publicKey = keyPair.PublicKey;
File.WriteAllBytes(privateFilePath, privateKey);
File.WriteAllBytes(publicFilePath, publicKey);

This is my first time trying to do anything more than open a webpage as a process.
I'd like to open a page in IE and then fill in a text box with the id being shown below in the small code snippet.
I think I can use WebRequest for this, but I've tried a few code samples I found online and it does not open the webpage in IE, so I'm not sure where to start to get a simple example working and build off of it.
<div class="formControl"><input name= "username" id= "txtlogin" maxlength= "75" placeholder= "Username" size= "25" type= "text" class= "" />

I found an addin called Selenium that will do this, but then I have to have additional dlls to my executable and it's 5mb, which is 10 times my exe's size and way overkill.
No one has ever opened a page and then posted data to the input id's?

Google will show quite some hits.
If you want to manipulate IE, you will have to launch IE and manipulate that.
If you want to fill in values in a webpage, you use a WebBrowser control.
If you want to submit the data without any browser, use the WebRequest.
