if you use pirated software you have to write :
private void sender_eventMethod(object sender, EventArgs YYAAARRRGGS)
:P
|
|

|

IMO it would be better to use a synchronization object, such as mutex or ManualResetEvent
|
|
|
|
|
Yes, that would be the professional way. But mostly a simple variable does it fine.

Your statement is contradictory. Professionalism means doing it the right way.

Can you explain why those approaches would be better than the bool flag in this specific case?
what can go wrong in this case when using a bool flag?
(can it blow up if the bool is both read and written to at the same time?)

Hi, I have been given a dll (built using either C or C++, but not COM) and am trying to create a wrapper class to call its functions (using importdll). I have the header file (.h) so I know the function names and parameters. The trouble is, I don't know how to map them to C#. So, is there a reference website that shows what types I should use in C#? There are pointers to GDI+ bitmaps, pointers to stucts and dereferencing as well as simple types like ints. Any suggestions for a reference website or even a tool to generate the code for me?
Thanks in advance
Andy

The best text in the world on remoting: Advanced .NET Remoting by Ingo Rammer
His website also provides alot of information, the first 8 sites that came up in Google provided lots of information, and I believe there is an article here on code project that gives a client/server chat example using remoting. I suggest you improve your search skills.

Does someone have some references on the commands ADPU for access to the smartcards?
I am trying to read the data from a smartcard using the winscard.ddl API . I succeed in connecting to the card but I don't find information on what commands to send 
thanks
|
|
|
|
|
Good luck.
SmartCard commands are typically specific to the particular card involved, and depending upon what the card is and what it is used for, you will likely never be able to get that information. The ISO specification (It has been too long... I don't even remember which one it was.) only defined a very few "generic" commands, and as I recall, they were just suggestions anyway.
I used to work for a company that developed its own SmartCard reader, and just to get sample cards and the command documentation to test with the reader, we had to jump through all kinds of legal hoops with the SmartCard vendors, involving all kinds of Non-Disclosure agreements, etc.
Don't hold your breath...

Use the event LinkClicked from LinkLabel and use this code:
Form form = new Form();
form.ShowDialog();
or
form.Show();

Whoda thunk it! A C# question in a C# forum. Please make your subject lines more meaningful. For example the subject "Link up multiple forms in VS 2003" would be much better.

I have a page of text painted on a tabpage panel. But I cannot highlight the text on it. How can I do it?
Thanks
|
|
|
|

I assume, from your question, that you are doing the following:
1) override void OnPaint()
2) doing a graphic.DrawString()
You will not be able to select text in that situation. The only way you can have selectable text is to replace the owner-paint function with populating a control that is meant for text selection....like, oh say textbox???!!!!!

I am developing Login Control where the user can enter username and password. in the Username and password box i should restrict the user from entering Special Chars, and other invalid keys.
i know i can compare the the value in Keydown event using Keys.Keycode, but it is very ugly to put all the Spl char comparision like if(e.Keycode==Keys.Enter || etc..). Is there any function or way to Compare the key pressed is a spl. char or not.
Thanks and Regards

Try MaskedTextBox!
But filtering using KeyDown is still my preference.

Think outside the box!!!!!
You have a group of keys that you want to have disallowed from entry in a textbox. So a simple solution to this would be something like this:
List<Key> invalidKeys = new List<Key>();
...
private void ThisForm_Load()
{
invalidKeys.Add(Keys.Enter);
invalidKeys.Add(Keys.Ctl);
...
}
...
if ( invalidKeys.Contains(e.Keycode) )
e.Handled = true;
