Set the KeyPreview of the containing form to true, handle the Form's KeyPress/KeyDown/KeyUp event depending on your needs and set the Button's Location property to the point you want.
Please only post once and give your post a title that indicates the problem in future.

Delete the second copy of your question, before it gets replied to.
Never post your email to any forum - unless you really like spam! CP will send you emails as necessary when people reply to you. (Just like this one)

I decided not too use it as a singleton (or in my case as I was being silly a "Global" object !).
Thank's

Ok. So what are you answering to?
Are you referring to some other article / post?
Then please post that link here or better, post this message within that same article or link.

So you deleted your original post to repost your request for code.... why?

so he decided to completely ignore forum guidelines, ignore and down-vote my earlier reply, delete the question, create a new thread on the same subject, and use a meaningless subject line. Not a compelling start.

Well it would appear that I was down voted as well... oh the calamity.

First of all I posted in this forum for the first time.( i know it is a mistake now).
Secondly if my code was working i will not be looking for help. About deleting my code and reposting the question. You only said that it does not look right.
Anyway i will do it myself thanx have a nice day

People here are more than willing to help out; however there are some rules to make that easier and to get things a bit streamlined. Good luck with those threads.

Hi
i am new in C#. i am developing a banking system in which each bank sends encrypted messages to each other. i am using 3-DES algorithm.
i am facing following problem.
user sends encrypted message to bank A and bank A decryptes it.here this algorithm works fine but when bank A sends this to Bank B then i am getting this runtime error
"Invalid character in a Base-64 string."
i am using the following code.
string cipherText = richTextBox2.Text.Trim();
string mykey;
byte[] keyArray;
byte[] toDecryptArray = Convert.FromBase64String(cipherText);
StreamReader objReader = new StreamReader("c:\\encryptkey.txt");
mykey = objReader.ReadToEnd();
objReader.Close();
if (mykey.Length < 24) mykey = mykey.PadRight(24, '.');
keyArray = UTF8Encoding.UTF8.GetBytes(mykey);
tdes.Key = keyArray;
tdes.Mode = CipherMode.ECB;
tdes.Padding = PaddingMode.PKCS7;
ICryptoTransform myTransform = tdes.CreateDecryptor();
byte[] resultArray = myTransform.TransformFinalBlock(toDecryptArray, 0, toDecryptArray.Length);
tdes.Clear();
data = UTF8Encoding.UTF8.GetString(resultArray);
the same code works very fine for first time decryption but not for 2nd time. i am getting error in
byte[] toDecryptArray = Convert.FromBase64String(cipherText);
plz help me.
thanx

So, when you look at it in a debugger, what is the invalid character and where did it come from? Are you sure there are no control characters getting added on somewhere?

Hi All;
I have created a user control that contains a generic list. When I instantiate this control in a Windows Form for some reason and array of the list type as (List<of type="">) is being added to the forms resources (.resx file). It runs ok for 2/3 times and then I get an error as follows:
Object of type 'NameSpace.Type[]' cannot be converted to type 'NameSpace.Type[]'. (where Namespace and Type are my class namespace and type.
Both list type and usercontrol are in teh same namespace.
Can anyone please help in clearnign this.
Thanks
Bin

I have had this problem before, but not for some time.
If memory serves it is caused by your having changed the Namespace.Type[] class/control/whatever in some way and when you next try to load the parent form it still has the 'old' style one serialized and of course cannot deserialize it. Again purely from memory the work-around is to delete the *.resx file for that form, although renaming/moving it might be safer from a restoration point of view.
Also a long, long, long time ago .NET 1.0/1.1 days this could happen if the 'build' part of the version information changed between runs. Not sure if this still applies though. The work-around here was to change the Version specification from [assembly: AssemblyVersion("X.Y.*.*")] to [assembly: AssemblyVersion("X.Y.*.1")] in AssemblyInfo.cs.
Hope this is of some help.

Hello Henry;
That's it. I have to remove the UC instance from my form everytime I do an update to it, before recompling.
Thanks

Hi,
That is an ugly piece of code. For one, lacking any indentation, it is hardly readable; please read the forum guidelines (how to ask a question) and use PRE tags. Then a lot of declarations are absent, making it hard to understand. I also wonder where the code shown resides, is it part of some event handler, maybe a button click one?
Furthermore, the definition of DoWork() is absent, and it seems like a strange way to specify the thread's jobs. I'm not sure how "x" will ever get from the thread calculation result into the ListView either.
I suggest you edit your existing message and fix it with PRE tags and declarations, so someone can maybe give you further directions.

Hello,
How can I measure the time that controls are being painted on a panel ?
Thanks,
berlus

If I understand you correctly you have a Form, a Panel on that Form, and some Controls on the Panel. The Controls get painted whenever there is a need to, and you would like to measure how long it takes to paint them. Correct?
I could explain how to get the measurement done (or what to change so it can be done), however I'd rather tell you that you asking this tells me (1) it is slow, and (2) you should fix that.
Event handlers, including the Paint handler, should execute in a snap, never keeping the GUI thread busy (or waiting) for more than say 20 milliseconds, otherwise the GUI experience would be bad (e.g. a window covering most of your form, then disappearing, would take too long for everything to settle; or you dragging the Form by its title would not follow your mouse smoothly).
I suggest you tell more about your current situation: which controls, showing what kind of data (and where it comes from), etc. Plus a detailed symptom description.

Thanks for your answer.
I'm developing a GDI+ (can't use direct draw or open GL) framework, and i'm trying to decide between two alternatives to draw a certain symbol.
In order to decide which method to use, i'm creating a PanelWithStopwatch (derived from Panel), and drawing on this panel the desired symbol.
I want to use the stopwathc to measure the time that each panel was painted.
I hope I have clarified the need for the performance test.
Thanks,
Berlus
