Hi,

that is too easy an assignment. Why don't you write code to flip the characters, so
"hello world" becomes "plɹoʍ ollǝɥ"

OK, thanks to everyone who gave me ideas and got my brain jogging

I have figured it out and I will post the code here so that if anyone else needs help they can refer to this

Console.Write("> Please enter an input\n> ");
string userInput = Console.ReadLine();
string[] words = userInput.Split(' '); // creates an array of strings

foreach (string word in words) // loops through the array "words"
{
    for (int i = word.Length - 1; i >= 0; i--) // loop through word with for loop.
    {
        Console.Write(word.Substring(i, 1));
    }
    Console.Write(" ");
}
Console.ReadLine();

P.S. Yes I kno this is a simple task for many of you, so thanks for not flaming me too heavily

CryptoStream Length

Hi,

I'm trying to encrypt some files using DES algorithm and calculating length as like below.

CryptoStream cryptoStream = new CryptoStream(existingStream, cryptoTransform, CryptoStreamMode.Read);
           this.dataStream = cryptoStream;
           //long l = ((FileStream)this.dataStream).Length;
           // The encryption algorithm can pad the data by a few bytes, so this line corrects for that.
           this.BytesTotal = Convert.ToInt64(Math.Ceiling(Convert.ToDouble(this.BytesTotal) / 8.0) * 8.0);
           this.BytesTotal = this.BytesTotal > 0L ? this.BytesTotal : 8L;

It works well for all text files, XML, HTML etc., but when it comes to MS-Word or Excel file it doesnt calcualte size properlly hence i couldnt write into by webrequest. Please let me know what changes are required to make this work right?

Thanks in advance.

we got the solution

// The encryption algorithm can pad the data by a few bytes, so these lines correct the byte count
int blockBytes = cryptoServiceProvider.BlockSize / 8;
this.BytesTotal = this.BytesTotal + blockBytes - (this.BytesTotal % blockBytes);

Now its working fine

You may use WebRequest

if FtpWebRequest works for FTP, then maybe HttpWebRequest might have something to do with HTTP?

you might try it

dynamic dropdown list box

Hi can somebody help me out from this issue...i have a dropdownlistbox which contains 1 to 15 nos, based upon the selected number i.e if i choose 2 that many dropdownlistbox will dynamically generated with some numbers populated in it. upto this point there is no problem.

my problem is if the user selects any number from the dynamically generated drop down then the selected index changed event should fire for each individually generated dropdownlist box.how to achieve this?

since the dropdownlist box is generated dynamically i dont knw how to write the selected indexchanged event for each dynamic control..
with this i have attached part of the codesnippet..please some body help

label2.Text = "No.of Modules:";
label2.Font.Bold = true;
tc1.Controls.Add(label2);
tr1.Cells.Add(tc1);

DropDownList ddLModule = new DropDownList();
ddLModule.ID = "DropDownListID" + (i + 1).ToString();
ddLModule.SelectedIndexChanged += new EventHandler(DDL_SelectedIndexChanged);

int nTotalRecords = 15;
ddLModule.AutoPostBack = true;
for (int i1 = 0; i1 <= nTotalRecords; i1++)
{
ddLModule.Items.Add(i1.ToString());
}

tc.Controls.Add(ddLModule);
tr1.Cells.Add(tc);

// for all the dynamically genarted drodpwn this event only fires ,i need to fire selcted indexchanged event for each control created dynamically??//

private void DDL_SelectedIndexChanged(object sender, System.EventArgs e)
{

for (int i = 0; i < this.myDDLS.Count; i++)
{
string ddlId = (string)this.myDDLS[i];
Control c = phdIterationDetails.FindControl(ddlId);
if (c != null)
{
DropDownList myddl = (DropDownList)c;
int ModuleRows = Convert.ToInt32(myddl.SelectedValue.ToString());
Session["modulerows"] = ModuleRows;
if (ModuleRows > 0)
{
CreateDynamicModules(ModuleRows);
}
}
}
}

If you know how to get it done statically (i.e. through Visual Designer), then you can easily find out how to do it dynamically, since all Designer does is generate some code, typically hidden in a file called xxx.Designer.cs

Open it, study it, read the documentation on things you might not be familiar with, and then create your own code.

Apply random number to multiple canvas objects

Hello.

I'm fairly new to WPF, coming from AS3. I have a series of canvas objects which I want to 'scatter'. I thought maybe I could do this by having the items in an array, then using a for loop to run the random number and double animation code on each one.

However I'm struggling to place the canvases into an array, can you in fact do this or would I need to think differently?

Regards.

PictureBox MouseUp event?

10-Mar-09 1:43

I have a problem, a PictureBoxes MouseUp event gets fired the moment you hold the mouse down, not release it, as it it should be.

I want to let the user select multiple PicturBoxes while he holds a mouse button down and stop selecting when the mouse button is released, however, if the MouseUp event gets fired the moment you press amouse button, but not relase it, that is not possible.

Does anyone know some kind of fix or work around?
How do I make the event fire at the right time or how do I let the user select multiple PicturBoxes with the MouseUp event?

Thanks in advance.

Hi,

First of all - please excuse my poor english.

I am trying to download html content from an url. Just the source-text of the site. When I open a website (for example www.google.com) in IE an look at the source-text (right mouse - view source text) the displayed text is different as if I do the same with Firefox.

I tryed using httpwebrequest, setting useragent, header-information etc. but never get the html content as displayed in IE-sourcetext. What am I doing wrong? Any hint would help.

I have been searching the forums the last 2 days for a solution of this problem but didn't find an answer. Perhaps my understanding of the process is wrong so please give me a hint for what i have to look for.

Best regards,

LC

The html may be dynamically created based on the browser being used.

Yes ... maybe it is, but is there a way to "simulate" being IE? ... Whatever I try it doesn't work right.

For your understanding: it's about filtering any links out of a website like a spider, source-text in IE shows the links as <href....etc.>, firefox and everything I've tryed in C# shows just javascript-code as result.

Is there a way to extract the links from the returned javascript/html-code?

Thank you for your quick answers Smile | :)
