help require? imran_rafique16-Dec-02 6:49 imran_rafique 16-Dec-02 6:49  I have created a service in c#. And I am executing a Process.Start command in this code ( OF SERVICE PROJECT) . that command(Process.Start ) is executing sucessfully for local drives but it throws Win32Exception (means There was an error in opening the associated file) at network path. for example path is \\computername\folder1\folder2\some.exe AND it heapens only with Service type application all other applications are executing any process at network path (i.e \\computername\folder1\folder2\some.exe)successfully with this command(Process.Start). Can any body tell how will I make my Service to execute any Process at network path? r00d0034@yahoo.com Re: help require? Andres Manggini16-Dec-02 12:13 Andres Manggini 16-Dec-02 12:13  Hi, Could it be that your service is running under an account that does not have sufficient permissions to access shared folders ?. Hope this helps. Andres Manggini. Buenos Aires - Argentina. Re: help require? imran_rafique16-Dec-02 12:36 imran_rafique 16-Dec-02 12:36  it did not help at all. service is running under admin account. r00d0034@yahoo.com Windows Form Control hosted in IE LJMorsillo16-Dec-02 4:34 LJMorsillo 16-Dec-02 4:34  Here's a story... I hope someone can help me write a happy ending in time for Christmas! I have a control <code>namespace WvfCtlNet { public class WvfCtl : System.Windows.Forms.UserControl .... </code> which I'm hosting in IE <OBJECT id="control" classid="http:WvfCtlNet.dll#WvfCtlNet.WvfCtl" name="control"> ... I'm not getting anything other than a little box (place holder) when the page is displayed. The control shows up in the GAC downloads ("gac /ldl") The version number agrees with the dll. When I look in Internet Options-Settings..-View Files... I see the following entry: ?FusionBindError!name=WvfCtlNet.dll WvfCtlNet.WvfCtl What the heck is this? (I think I know that Fusion is a technology related to 'no touch' installation but that's about it!) Why doesn't my contol pop up? I works when hosted by an Windows Forms app. Worst of all - This was working a week ago - I've not made any config changes, though I did recently install the Microsoft Web Services Extensions (WSE) pack. I am flummoxed! Thank you. Sincerely, Lindsay xor strings?? Karavaev Denis15-Dec-02 23:52 Karavaev Denis 15-Dec-02 23:52  How to make simple xor in C#? ===================== http://wasp.elcat.kg Re: xor strings?? Kannan Kalyanaraman16-Dec-02 0:13 Kannan Kalyanaraman 16-Dec-02 0:13  Hi, If you are looking at nos. then you can use ^ operator. For strings, you need to first convert them to bytes, <br /> ASCIIEncoding enc = new ASCIIEncoding ();<br /> byte[] keybytes = enc.GetBytes (key);<br /> here key is of type string once you have converted to bytes, you can work on them. Hope this helps. Cheers Kannan Re: xor strings?? Karavaev Denis16-Dec-02 0:46 Karavaev Denis 16-Dec-02 0:46  string txt1 = "some_text"; string txt2 = "anything_else"; ASCIIEncoding enc = new ASCIIEncoding(); ASCIIEncoding enc2 = new ASCIIEncoding(); byte[] kb1 = enc.GetBytes(txt1); byte[] kb2 = enc2.GetBytes(txt2); MessageBox.Show(kb1 ^ kb2); Operator '^' cannot be applied to operands of type 'byte[]' and 'byte[]' damm, what I did wrong? ===================== http://wasp.elcat.kg Re: xor strings?? Christian Graus16-Dec-02 0:54 Christian Graus 16-Dec-02 0:54  You need to ^ each byte, not the whole lot. You need to step through the strings, and can only perform the operation on the set of bytes that exists in both arrays, so unless the two strings are always the same length ( which they are not in your example ), I doubt you're going to get what you wanted.

Christian Graus16-Dec-02 1:09 Christian Graus 16-Dec-02 1:09  Yes, there is apparently heaps of encryption/decryption stuff in .NET, but I confess to not having used any of it, yet.

Kannan Kalyanaraman16-Dec-02 1:04 Kannan Kalyanaraman 16-Dec-02 1:04  You will have to iterate the array and do the operations individually on every byte. <br /> for(int i=0; i<10; i++)<br /> kb1[i] ^= kb2[i]; <br /> Cheers Kannan Re: xor strings?? Daniel Turini16-Dec-02 0:22 Daniel Turini 16-Dec-02 0:22  Besides the above suggestion, you can after this, create a BitArray with the byte[] and use its Xor method. I see dumb people Dynamically Generating Data for a Waveform Graph Control Matthew Alan Gray15-Dec-02 16:27 Matthew Alan Gray 15-Dec-02 16:27  I am currently developing a waveform graph control, and I am having difficulty in dynamically displaying multiple plots. Basically, I want to display anywhere from one to an undetermined number of plots on a single graph; I could use arrays to do this, but there would be difficulty resizing the arrays if I set the size of the arrays too low, and there would be wasted resources if I set the size of the array to high... What I need is an efficient way to add, update, and remove structures representing plot data that can be easily and efficiently resized -- is there a straightforward way to do this in C#??

COM rules state that to check if two interfaces point to the same COM object, QI both interfaces for IUnknown directly, and compare the results. How do I do that in C#? If I could find a souvenir / just to prove the world was here   [sighist] Re: same COM object? Rama Krishna Vavilala15-Dec-02 16:52 Rama Krishna Vavilala 15-Dec-02 16:52  Equals() method takes care of that for you or == operator. The mistakes made in this API make me realise that Microsoft has become big enough that it can shelter morons. If anyone working for me wrote anything this bad and tried to release it, I would kill them and display the body as a warning to the rest of the team. - Christian Graus about C# - GDI+ ArrayList == vector and list ? peterchen15-Dec-02 9:59 peterchen 15-Dec-02 9:59  Hi, Is ArrayList a "reasonable" replacement for both vector and list?

Debugger anomaly Paul Silvernail15-Dec-02 5:25 Paul Silvernail 15-Dec-02 5:25  This is a first !!!! After working on my final project for school late last night, I woke to find the debugger gremlins had come. When I try to debug my project (F5) MS VC# hangs. The task manager show a process for my app was created, but the app never shows up as a task. I tried deleting the debug directory and doing a rebuild, no luck! If I execute without the debugger (ctrl+F5), either in release or debug build, the app runs. Sounds like a real world release nightmare If anyone has ideas, please please let me know. Thanks, Paul Re: Debugger anomaly leppie15-Dec-02 5:34 leppie 15-Dec-02 5:34  Paul Silvernail wrote: I tried deleting the debug directory and doing a rebuild, no luck!
