What method are you using to create the tables?

Hey all,
Actually i should say that i have a Decrypting problem  !
I am trying to use a certificate to prove the client/server identity in my application. I was sending a welcome message from the server to the client, encryption/decryption worked smoothly, but this message is just a string like the client number, name of the computer where the server is running and all that...
Now when i am doing this:
Publisher publisher = new Publisher(new Init().Certificate());
byte[] message = Encoding.ASCII.GetBytes(new Encrypting().Encrypt(new Init().GetRawCertData(), password));
....
and sending it over the "Network", i am getting a bad data exception... something about a wrong character in the Base64 String.
I am sending fixed length bytes[] and when i am just sending strings it works. But when i try to change the type of data to send it messes up.
My logic to Encrypt/Decrypt is create an instance of the algorithm to use, i use the login password to encrypt/decrypt and i init the key and IV of the algorithm with them, a memory stream and the crypto stream... and return an array of bytes.
Maybe i am doing something wrong, any idea of how to use the certificate better, I am extremely new to Certificates and Digital Signatures. I tried SSL Stream but i could not make work .
Thanks in advance !
Best regards!!!

HI guys,
I have resize picturebox (say picMain) to the size of form.There are many picturebox inside picMain. Now I am moving child
picturebox ( on mouse_move event) on picMain. I am getting refresh problem while dragging child picturebox.
I had use Invalidate(),Update() and Refresh() method of current movable child picturebox but not getting precise solution. It seems like child picturebox ghost is following it. Child picturebox takes more times to refresh.
Instead of picMain if I work with main form then it work very well. I think picturebox has less ability to refresh faster compare
to form (am I write??).
I want same effect as what we dragged item from visual studio toolbox and move around in the form.(its so smooth)
pls give the solution
thanks in advance.
Regards

Sounds like you read an article and should have posted your question in the forum below that article.

How would I tell if a textbox's text is a number or string? Thanks.

TextBox.Text is always a string; you can get its numeric value if YourNumericType.TryParse()
returns true.

Does anybody know how to find the memory usage for an object instance or instances? Specifically, I'm trying to figure out how much overall memory it takes to retreive data from the database and populate the object instance in two different ways. I attempted to get the memory usage of an object instance by calling System.GC.GetTotalMemory() before and after the object creation and take the difference, but it didn't work in some cases. Below is some example code on what I'm trying to do:
<br />
public int FindMemoryUsage()<br />
{<br />
SqlDataReader reader;<br />
<br />
int memoryBefore = System.GC.GetTotalMemory(false);<br />
reader =
The result of the function should return the memory usage of the reader which is dependent on the results returned from the database. However, I tested this by comparing the memory usages between retreiving just a few records and a whole lot of records from the database and the result was approximately the same. Can anyone explain to me what I'm doing wrong? Any help is greatly appreciated!!
P.S. - Why does using the 'code' tag fail to indent anything?

The problem is that the GC may not release memory when it's no longer used. So if you run your first test and it causes your application to jump to 100MB, then your next test only needs 50MB, your application will probably still have 100MB allocated. Depending on how much free space you already have, you may not see any differences between running your two tests even if the "large" test is performed second. Basically, the GC memory totals are not a good way to detect memory usage.
You can use performance counters[^] to try to track down which test is better. You can also use Son Of Strike (SOS) to get the data from the raw objects. The blog entries here[^] and here[^] are a good place to start.
Take care,
Tom

I'm looking for an C# API, subscription-based service, or database that will allow me to pass a zip or city/state/zip with a distance parameter i.e. ("redmond","wa","98052",20) and get back the surrounding cities within the specified distance, without getting into some kind of gps coding nightmare. Does anyone know of such a thing?

By shipping the DirectX runtime installer with it and making sure that any interop dlls that get build with your proejct are included.

Hi All,
What is the design pattern (Interfaces?) to use in C# for a object Factory?
Thanks,
Jeff
|
|
|
|
|
Err... the design pattern to use is the Factory Pattern, if you want to use the Factory Pattern, that is...
As to the how to, I've found this a worthwhile (if not free) resource:
http://www.dofactory.com/Patterns/PatternFactory.aspx[^]
"On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't.
"I phoned Camelot and they fobbed me off with some story that -6 is higher - not lower - than -8 but I'm not having it."

Hi Martin,
Thanks. It's been too long since I had a Design Patterns class (and I cannot find the text book from college).
In the examples, it seems Main() must know 'a priori' what classes to instaniate. Is this knowledge included in the Factory, or is this a poor example?
Perhaps if I briefly explain my problem domain, it will help cut to the chase.
Jeff
I parse a flat text file. Each token will become a distinct object. So I would like to:
Token t = NextToken()
Object o = Factory.CreateObject(t) o will then be Type1, Type2, Type3, etc. Factory::CreateObject would be a message cracker:
if( t.field = 1 ) { return new Type1(t); }
...
if( t.field = n ) { return new TypeN(t); }

Hey Jeff,
I had to have a good long think about what you're trying to do (I'm no pattern guru myself, which is why I recommend DoFactory) and came accross this article which might prove useful:
http://www.codeproject.com/cs/design/csdespat_4.asp[^]
and this one:
http://www.codeproject.com/useritems/BuilderPattern.asp[^]
"On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't.

I have a problem where I've got a large amount of nested if statements.
they were all working and executing the correct numbe of times until I added some loops at the start.
The debugger is showing that it executes the first section and then starts again without going to the next condition. I know I have to change the condition maybe. This is the first section that gets executed continuously. Obviously there will always be rows, but the rest of conditions say, if checkedbox is ticked, or combobox is selected bla bla, so I can't see why (if I select a combobox item and click search, it is not executing). Is there a way of telling the code that you want to end the loop after all the entries in the database have been covered? Make sense?
foreach (DataRow row in dsapps.Tables[0].Rows)<br />
{<br />
<br />
if (row["EmployeeID"].ToString().Equals(EmployeeID.ToString()) == false)<br />
{<br />
if (EmployeeID > 0)

Missing a curly brace somewhere? How about an errant ";"?

Thanks yes I worked it out. It was just a silly curly brace. i wasn't missing one as such, I just had to move them around.
Wasn't worth the question. Sorry about that.
