I may be an Idiot for asking this but it is friday and my brain is fried, lol. But in a C# Class can you just declare an Enum? Other Classes will use this single Enum as a standard across the application.

Yes, you can. For example:
public class IceCream
{
protected IceCream()
{
}
public enum Flavor
{
Vanilla = 0,
Chocolate,
Strawberry,
}
}Client classes can then refer to objects of type IceCream.Flavor that could have a possible value of IceCream.Flavor.Vanilla.

Hello,
I have got an problem with Painting in C#. When i resize an image, the right side will get more and more transparency.. i dont want that, but i dont know how to fix it.
A part of the code:
<br />
protected override void OnPaint(PaintEventArgs e)<br />
{<br />
base.OnPaint(e);<br />
<br />
Graphics g = e.Graphics;<br />
<br />
g.DrawImage(Properties.Resources.WindowTopMiddle, 12, 0, this.Width - 22, 40);<br />
g.DrawImage(Properties.Resources.WindowTopLeft, 0, 0, 12, 40);<br />
g.DrawImage(Properties.Resources.WindowTopRight, this.Width - 12, 0, 12, 40);<br />
<br />
g.DrawImage(Properties.Resources.WindowLeft, 0, 40, 8, this.Height - 52);<br />
g.DrawImage(Properties.Resources.WindowRight, this.Width - 8, 40, 8, this.Height - 52);<br />
<br />
g.DrawImage(Properties.Resources.WindowBottomLeft, 0, this.Height - 12, 12, 12);<br />
g.DrawImage(Properties.Resources.WindowBottomRight, this.Width - 12, this.Height - 12, 12, 12);<br />
g.DrawImage(Properties.Resources.WindowBottomMiddle, 12, this.Height - 8, this.Width - 22, 8);<br />
}<br />
You can see, some images have their normal size, and wont get the transparancy..
But the sides, top/bottom middle will.
I dont have changed any default settings, the editor I use is 'Microsoft Visual C# 2005 Express Edition'
Could you please help me?
I look forward to your reply.

Hi guys!
I have a click event in one of my forms which is supposed to open another form. How can I ask it to close the current form and open the new form. Basically before I open the new form, close the old form.
Thanks for your help in advance!

Try this:
Form1.cs
--------------------------
Form2 form2 = new Form2();
form2.Show();
form1.Close();

n the click event handler, you could write something like this:
this.Close();
formw.Visible=true;
I guess it should work.

Thank you guys for your help. Neither of these worked. If i use form2.show(); and then form1 or this.close(); it closes both the forms. If I use this.close and then form2.showdialog() offcourse it closes form1 and never opens form 2. If I use form2.showdialog and then this.close then it opens form2 but form1 stays open until I close form2.
What I am trying to do is close form1 as soon as form2 opens. Please help!!!

If Form1 is the main form of your application then on closing it terminates the main thread. So Form2 are closed too. You should hide Form1 and close it only after Form2 is closed. Try this in your Form1:
<br />
private void ShowForm2()<br />
{<br />
Form2 form2 = new Form2();<br />
form2.Closed += new EventHandler(form2_Closed);<br />
form2.Show();<br />
Hide();<br />
}<br />
<br />
private void form2_Closed(object sender, System.EventArgs e)<br />
{<br />
Close();<br />
}<br />

Hi,
I want to have a little suggetion from you. I am working in a company which needs to connect to several other companies. Now we need to send data to & from other companies using public domain network like Internet. I want to know what is the best, most efficient & particularly secure way of doing it. Web Services, Sockets or any thing else. The amount of data is average i.e. not very small and not very big.
Regards,
Wasif Ehsan.

I don't know what kind of budget you have for this project, but this[^] would be a good solution for your needs.
I think the cost, excluding hardware, would be around 20K, including licenses for SQL Server 2005 and BizTalk 2006.
I work with this product since 3 years and I must admit I like it.

Imho, web services would be the way to go.
If you're unable to keep a server running at either end and don't require the transfer to be in "real time", you could (programmatically) email each other the data.

I mean to say i want to implement that thing in my own application. I dont(can't) use any already built products like BizTalk etc. I am in process of making an application for which i needed suggestion.
Regards,
Wasif Ehsan.

I wasn't suggesting you use BizTalk.
Like I said, you could use webservices to easily establish a data transfer (and processing, if you like) conduit. If you can't keep the webservice servers running at all times, you may want to consider a non-realtime SMTP/POP solution. The latter only requires access to an email account.

Tcp sockets would be my first choice, if it's just data transfer.

Hey, i have an int[] that i need to be able to set in the code, but i also want the user to make sure the values are set right. i have a base class that every node in my flowchart uses then to hide and show specific properties i just cast the base class to an "info" class that only shows the properties that matter to that node. i do this for display purposes only the code treats everythign the same...so for this property there are getters and setters in the base class..but in the "info" class i have the property set to read only, and i've tried removing the set part of its declaration, but nothing helps. the first line(where it has the name of the property, and also says Int32[] array) is read only, but when you hit the + sign to expand the array to see what values it contains, the values arent read only. if it matters the values are id numbers that are automatically set for each node, that hte user can see but i dont want to trust them to type them in(they're set via a context menu on the link between two of em) the user just says set to 0 or 2, with 0 or 2 bieng spots in the array and the value being the id of the node that link goes to...so i need the values visible in the property grid just not editable..
sorry for the long post, but most of the time i get more questions than answers in other forums...i'm tryin to get out of that habit.
thanks for your help

yeah thats what makes the first line read only, but doesnt seem to affect the rest. i've also tried removing set from the property declaration but that doesnt seem to be working either.
|
|
|
|
|
Removing set won't work because while the array itself cannot be set to another array, the individual elements can be changed. What you may want to try is use a ReadOnlyCollectionBase. It may be what the properties grid needs to see to know that the elements cannot be changed.

how would i cast the int[] or arraylist or anything to the ReadOnlyCollectionBase for just the properties grid..i still need to edit the values..i just cant let the user change them via the property grid.
|
|
|
|
|
n/m i have the desired result..i turned it into an ArrayList and used the ArrayList.ReadOnly() function to prevent changes..the only problem is that now it wants to use the collections editor instead of expanding the list like it does for arrays...if you have any ideas on how to force it to show as an array but stay read only it'd be great but if not i'll try to convince them to live with this.
Thanks for all your help
John.

Try sticking this on the top:
[EditorAttribute(typeof(System.ComponentModel.Design.ArrayEditor), typeof(System.Drawing.Design.UITypeEditor))]<br />
<br /> Using the EditorAttribute allows you to change the UITypeEditor being used in the properties window. When writing a control, this is how you would create your own custom editor for a particular property. From what I can see, there's a CollectionEditor and an ArrayEditor. Using an ArrayEditor may not work with an ArrayList, though. If I weren't lazy (or at work) I would actually create a project and try this out myself. Oh well, let me know if that works.

no that didnt work with an ArrayList, tho it was a good idea...i didnt even see the ArrayEditor when i was lookin through there. I think i need to have my eyesight checked. i think they're ok with the collection editor now...but now instead of seeing the value the code needs, they want me to show the text of that node. Kind of like a SelectedText, SelectedValue deal...i was thinking of using another dimension on my array somehow. i'll try it out. btw this is really off topic but i'm taking my g/f to see a play tonite(one of her favorits) and i have a nice boquet of flowers to give her, what do you think give her the flowers at home infront of everyobdy, or take them to the restaurant to use as a centerpiece for the table, then take home from there?
thanks again.

Damn, oh well. You might want to try a type converter so that it shows the string representation as the text for the node.
I would say either way is going to get the same reaction, as long as she doesn't know it's coming. My gf always loves getting flowers. If you give it to her at home, she can put them in water and they'll last longer. And you won't have to carry them around everywhere. That's my vote anyways...

I got it working, i created a class NavData which had a string and int arrays as the only members and for display i just return an arraylist created from the string array. works pretty good. Thanks for your help...she said she loved the flowers and thought it was a good idea to not carry them around all night. the only downfall was that they were fake flowers. i made some roses out of dollar bills and mixed em in with some very nice blue/purple and white silk flowers so that she wouldnt end up w/ a few dollar roses and nothing to do with em when the real flowers died.
Thanks for all your help.
