Yes I received a mail from them. The problem is as I understand, is that now private workspaces does not have that clause. I dont see the point. OK, maybe one step closer, but I still want share my code with others and allow them free use, not code for MS. The issue is actually much more complicated as my library is already bound to the license of the BASS library. Basically, by GPL'ing my library, I just let the user refer to BASS's license. So unless MS feels like dishing out some $$$ for BASS they cant use my lib to make $$$. Hell, now I'm even more confused Mad | :mad:

Hi,
I want to create my control witch have collection (containing only MyControlItem objects) as a property.
(Something like ImageList with property called Images)
And I want to use Collection Editor (in design mode click on "...").
But I don't know, how to change type of objects that are added (in Collection Editor) to the collection from object to MyControlItem.

Thank you

(and i'm sorry about my english)

I don't know how to do this
What's wrong with this:

<br />
  public class DropDownItem<br />
  {<br />
    private string szName="";<br />
<br />
    public DropDownItem() {<br />
      szName="DropDownItem1";<br />
    }<br />
<br />
    public string Name {<br />
      get {<br />
        return szName;<br />
      }<br />
      set {<br />
        szName=value;<br />
      }<br />
    }<br />
  }<br />
<br />
  public class DropDownCollection : CollectionBase <br />
  {<br />
    public DropDownCollection()  { }<br />
    <br />
    public virtual void Add(DropDownItem val) {<br />
      this.List.Add(val);<br />
    }<br />
  }

Have you got some sample source or link ?
Thank you

Hi
Everything seems fine Smile | :)

But (isnt there allways a butt?) you may need to add some extra methods to implement.

Also, implement the collection in your class as follows:

public class MyClass 
{
  DropDownCollection ddcol;

  public MyClass()
  {
    ddcol = new DropDownCollection();
  }

  public DropDownCollection DropDownItems 
  { get { return ddcol;} } //note, NO set property
}

Nave a look at this as well, very handy for creating Strongly typed collections Smile | :)

I was thinking about this. Perhaps it needs the indexer or the GetValueAt() functions implemented.

OK I looked at the CollectionEditor's docs:

Notes to Inheritors: This editor can edit collections that have an Item property. The editor can determine the type of the collection from the Item property, if it exists. If the collection does not have this property, or if you want to provide collections of more than one type, you can override certain protected members of this class to customize the editor to support other types of collections.

Problem with DrawString in OnPrintPage handler

25-Sep-02 9:25

That's it

Rado24-Sep-02 11:17

Hello everybody,

I have a strange problem with DrawString in my OnPrintPage event handler Frown | :(

I need to print a few lines of text (field names) that is right-aligned. I'm using StringFormat to set the text alignemt and a RectangleF instance to set the coordinates. This is the code snippet:

StringFormat formatRight=new StringFormat();<br />
formatRight.Alignment=StringAlignment.Far;<br />
....<br />
RectangleF rectRight=new RectangleF(m_nMarginLeft+80,m_nMarginFields, 50, 30);<br />
e.Graphics.DrawString("Field name 1:", m_fontField, Brushes.Black, rectRight, formatRight);<br />
e.Graphics.DrawString("Field 1 value ...", m_fontGeneric, Brushes.Black, rectRight.Right, (float)(rectRight.Top-0.5));<br />
<br />
rectRight.Offset(0,m_fontGeneric.GetHeight(e.Graphics));<br />
e.Graphics.DrawString("Looong field name 2:", m_fontField, Brushes.Black, rectRight, formatRight);<br />
e.Graphics.DrawString("Field 2 value ...", m_fontGeneric, Brushes.Black, rectRight.Right, (float)(rectRight.Top-0.5));<br />
...

(Page units are milimeters) The problem is, that the fields are actually not exactly right aligned. The longer the text is, the more it is offset to the left (i.e. when printing it makes some 2 milimeters difference for field names which are twice/half the size of each other). The same thing happens when I use one multi-line string in a rectangle of larger height. I have absolutely no clue of what can be wrong? Confused | :confused:

Therefore any clues are highly appreciated Smile | :)

Am I doing something stupid or what? Thanks for any help.

Have a nice day,
Rado

Getting info on drives

Hi,

I can use Directory.GetLogicalDrives() method to get the drives attached to the computer but it only returns an array of strings which contain the drive letters (i.e. A:\, C:\, D:\, etc). What I want to know is how can I get the volume names and is there a way to find out the type of drive (floppy, hard drive, CD-ROM, networked) within the .NET framework. I noticed in the SDK documentation that there appears to be a VB.NET function that will get the volume names, but there doesn't appear to be one for C#.

Thanks

WJ

MSDN is full of errors. If it is .NET any language can be used Smile | :)

BTW what is the "VB.NET function" called?

I think it was the dir() function described here:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vblr7/html/vafctdir.asp

At least I think that was the one I was looking at earlier, it so bloody hard to find anything in MSDN and even harder to find it again. Anyway, it appears to be a function that is specific to VB and not part of the .NET framework itself. I couldn't find the same function anywhere within the .NET class library. What gives?

leppie24-Sep-02 10:58

I guess you will have to use WMI then... Have a look at the System.Management namespace.

Hello,

I know the tree control is one of the build-in components inside the toolbox of VC.NET C# window form, but it seems missing in web form control toolbox. The main purpose for this is that I got a database organized like tree and require to show it in ASPX. The DataGrid control cannot fit in my requirement.

Any suggestion?

Thanks.

How to use initialization of dialog

24-Sep-02 6:49

In VC++ i've always used the emessage WM_INITDIALOG.

In C# and dialog inherited from System.Windows.Forms.Form is this message
not attended.
I tried to do it in this way:

protected override void WndProc(ref System.Windows.Forms.Message m)<br />
{<br />
<br />
  switch(m.Msg)<br />
  {<br />
      case WM_INITDIALOG:<br />
          //some works<br />
          break;<br />
      default:<br />
          break;<br />
  }<br />
   base.WndProc( ref m);<br />
}

but it dosen't work Cry | :((

. I mean, that with little help of my friends, i should
do it !!!

Best regards
