What is the StrValue that you pass to the streamwriter?

Hi,

strValue is the text that needs to be encrypted.

Can I not convert the string to a byte array and then pass it to the memorystream? Won't this work too? How do I retrieve the encrypted string once the process is complete?

Hi,

In the code used to encrypt add the following statement to get the encrypted text into a string variable strRtnvalue.

strRtnvalue = Convert.ToBase64String(ms.GetBuffer(),0,Convert.ToInt32(ms.Length));

What text encoding must be used for the byte arrays? I'm using the UniCodeEncoding. But I keep getting an error that the key length is wrong for this algorithm. But my key is 48characters in length and the IV is 16cahracters in length.

Form freezes on async webservice call

Hi people,

I'm having a rather weird problem.

I have tried the code in this article http://www.codeproject.com/cs/webservices/AdvAsynchWebService.asp[^] and it works perfectly well. Now I'm trying to use the same technique in my windows form. I call a webservice method asynchronously that returns a factorized version of a number I send (example on MSDN at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconinvokingwebservicesasynchronously.asp[^]) When I display the resulting string in a messagebox, everything works fine but when I try to display the result in a label on the form, something goes wrong and the form freezes. It is frustrating to see a working example and not being able to make your own example work Confused | :confused:

Does anyone have any idea why this is happening and how I may resolve the issue? I can post my code if necessary.

Thanks,
Talal

I have a listview-control in detail mode with two columns. The columnheaders are clickable, but how can I detect which columnheader was clicked.
And which event should I check?

else if(e.Column == 1)<br />

  //...<br />

i don't think that it is possible to iterate
through foreach becouse i didn't found any
class for combobox items.

In a combo box the items are just strings so you can do this:

foreach (string itm in comboBox1.Items)
{
MessageBox.Show(itm);
}

Not always true.

The Items property is an ObjectCollection because you can stuff whatever you want in the collection, and render the Items yourself in a custom drawing routine. It's usually strings, but not always.

Very true.

Of course HOPEFULLY if you have stuffed something else in there you know what it is and can write the appropriate foreach loop. And if not I guess you can always treat everything in there as an object and write the foreach loop that way.

Guess I need to be a bit clearer around here with all you guru's watching Laugh | :laugh:

I want to ask that if I want to go to last child folder of any root folder..How can i do that...?

Following example will help to understand my prob.

like- c:\Data\Data1\Data2\Data3

c:\Data\Data1a\Data1b\Data1c

in this data is root folder in which if has 2 sub folders.

Now i want to reach folder Data3 and Data1c

foreach (string directory in Directory.GetDirectories(folderPath))

By using this code I can reach upto Data folder not inside of this folder.

This will help u most.

Thanks,

Hitesh
