There is an article here on Codeproject presenting A flexible charting library for .NET[^] that implements the described behaviour. Either use this library or take a look at the source code to see how the autoscaling is accomplished.

Hi

I think that you have a list of enities( say products) and want to add it as a piece of information into another list (say an order items list) and then enter its amount.

I have an enum say enum1. It has four fields f1,f2,f3,f4. I have allowed this to be set with multiple values. The enum1 is shown bellow:
public enum enum1
{
f1=0,
f2=1,
f3=2,
f4=3
}
But this allows enum with any combination of values to be set. I want this enum with particular restricted combination (say f1|f2,f2|f3, and f1|f4 only) to be set. How can i accomplish that?
Thanks.

Hello
You could create a property of the enum1 type
public enum enum1{ f1=0, f2=1, f3=2, f4=3}
private enum1 myEnum1;
public enum1 MyEnum1
{
get ( return myEnum1; }
set
{
if (value == f1 || value == f3)
myEnum1 = value;
else
throw new ArgumentException("Invalid assignment");
}
}
Otherwise you could create different enums
public enum enum1{ f2=1, f4=3}
public enum enum2{ f1=0, f3=2}
for example.
Kind Regards,
John Petersen

Thank you very much. And from your side i desires for welcome.

If you intend the enum to allow for OR'd combinations as you imply, you should decorate the enum with the Flags[^] attribute.
This attribute indicates that an enumeration can be treated as a bit field; that is, a set of flags. Bit fields can be combined using a bitwise OR operation, whereas enumerated constants cannot.
Bit fields are generally used for lists of elements that might occur in combination, whereas enumeration constants are generally used for lists of mutually exclusive elements. Therefore, bit fields are designed to be combined with a bitwise OR operation to generate unnamed values, whereas enumerated constants are not. Languages vary in their use of bit fields compared to enumeration constants.
Your code will compile without the Flags attribute, but it helps the compiler, the runtime and other developers understand how the enum is supposed to be used.

In a method i have two strings first is a property name i.e. "Text" and second is its value "MyName" as well as I have a control on my web form i.e. TextBox1 now on the basis of given string how can I set the TextBox1.Text = "MyName". The problem is I didn't found any property collection with control object and through reflection i can access properties but in that case those were not attached with a perticular control. How can I map the Text property of TextBox control through string "Text"???

Hi,
I have a lil question about how to change te way the program handle things.
I have a device attached to my serial port.
Thi device can take several commands, and it returns something back which i can read on the screen. But after every command i send to the device, there should be a thread.sleep(1000).
Since i send alot of commands automatically to the device, i rather want it to wait till it gets the info and then send it back.
Because the sleep(1000) isnt always enough. Sometimes it needs a lil more time to reply.
So i want to make an event handler which waits for a reply and than continue.
This is a peace of the code how it looks like:
serialPort = new SerialPort("COM1", 19200, Parity.None, 8, StopBits.One);
serialPort.Write(command);
Thread.Sleep(1000);
serialPort.Write(command);
Thread.Sleep(1000);
serialPort.Write(command);
Thread.Sleep(1000);
serialPort.Write(command);
Thread.Sleep(1000);
Can someone help me how to make an event handler for this?
Thanks in advance!

Hi,
In Visual Studio 2005 the serial port control has events. And one of them is DataReceived. Try using that event.

Hi
I think that you can use AsyncCallBackDelegate to do what you want.This way you can run a command Asynchronously and when its done you callback delegate will be executed.You can have a delegate to run your command and in its BeginInvoke moethod you will pass a AsyncCallBackDelegate.

I dont think there are someone being kind enough to convert the code
for you as the task will take about 1 to a few days.
Instead you may learn C# (easy to pick up) and diy

Hi...
Am having a java project which i have to now convert to a .NET project.
I tried to develop an j#.NET project and implement the logic in this project.
My project is all about images ,so i need to import javax.swing.*.But i couldnt do it.I am able import java namespace.
WHy is it so?How can i create swing applications?[i found a sample app in http://msdn2.microsoft.com/en-us/library/96etzbdw.aspx[^]but i couldnt find the dll specified there to be added as reference]
Also pardon if this is not the right place to post the forums of j# and kindly redirect me to appropriate forum topic.
Thanx

i even dont know why J# exists. it was born after a fight between MS and SUN.
why dont you think about rewriting this project in C#? you`ll learn a new and neat language (if you still dont know yet). Besides, C# and Java are very similar with each other.

You're really better off with C#.
J# is just a handicapped version of C#. J# has extremely close syntax, but fewer features.

Dear all,
I am trying to find the easiest way to give a keyboard shortcut to a command button like CTRL+K or F9 etc. Can i also give the shortcut key to ToolStripButton? How?
Thanks...
|
|
|
|
|
Hi,
i dont think there is a direct way to assign CTRL combination to command button. but you can always use the ALT+ combination by just typing the "&" before the character in the button text property.
if you anyway want to give CTRL combination or F9 like shortcut key you can use the form keydown event and check for the key combination pressed and raise the button_click event manually.
Hope this works.
