I have a namespace (NetworkManagement) that subclasses a
combobox and a treeview and loads each with some
directory info for a given PC....

I'm instantiating these controls from another namespace
(NetworkManagement.Demo) which contains the Windows Form
object that contains a standard (non-subclassed) listview
that I need to update based on a click in the treeview in
the NetworkManagement namespace.....

The two namespaces live in different assemblies... eash assembly lives in a project that is in a single solution... so the solution contains a Windows Form project and an assembly project with subclassed controls.

I need to be able to access the listview in the Windows Form from the
subclassed treeview in the other assembly... can someone clue me in as to how
this can be done?

Look in the Controls collection of the form, or in controls within that form.

thanks for the reply, but I'm not sure how to access the Form's controls programmatically... the name of the form object is ServerComboBoxForm, inheriting from System.Windows.Forms.Form. It contains the subclassed controls that I mentioned earlier, but the subclassed treeview needs to be able to talk to the form's listview, so I need a way to do this from the the assembly that contains the subclassed treeview...

thanks for any help...

Owner Draw...

Hi there guys,

1. I have owner-drawn list boxes on my form, everything draws alright and perfectly - but it flickers... so does anybody have the perfect solution for flicker free owner draw?
2. The drawing doesn't show well after drawing it the first time and after scrolling up... what to do?
Update() doesn't work well in this case, and I know it does redraw.

Thanks a lot!
I owe you all one...

Hmm, sorry - I didn't create my own control and the drawing flickers upon scrolling, and in the demo of the above article it flickered when I scrolled.

Anyway, the major problem I have is the non-updating areas... and I did call Invalidate() or Update() or Refresh(), and the DrawItem proc was entered into. Any suggestions?

Thanks!

WebBrowser API problem.

Hello,

I'm extensively using the Webbrowser control and everything is almost fine...
Actually I found a strange problem.

I crawl to a page containing the following code:

When using the IHTMLAnchorElement and asking for the 'href' property, I get the following result:

http://pubs.mgn.net/event.ng/Type=click&FlightID=6121&AdID=17734&TargetID=1165&Segments=108,143,292,365,382,1035,1227&Targets=273,1165&Values=31,43,51,60,72,81,91,100,110,150,206,213,237,474,601,625,763,934,938,940,1007,1009,1046,1253,1282,1448,1907,1963,2018&RawValues=&Redirect=http://www.fnac.com/Shelf/article.asp?PRID=1391122&Origin=2003.2.10.12.24.24.0&OriginClick=yes

But If I issue an HTTP GET request, I get a 404 error (after redirection, the web server is a Netscape Entreprise Server).
I know that if I use this URL instead (like IE does !), I will work:

http://pubs.mgn.net/event.ng/Type=click&FlightID=6121&AdID=17734&TargetID=1165&Segments=108,143,292,365,382,1035,1227&Targets=273,1165&Values=31,43,51,60,72,81,91,100,110,150,206,213,237,474,601,625,763,934,938,940,1007,1009,1046,1253,1282,1448,1907,1963,2018&RawValues=&Redirect=http:%2F%2Fwww.fnac.com%2FShelf%2Farticle.asp%3FPRID%3D1391122%26Origin%3D2003.2.10.12.24.24.0%26OriginClick%3Dyes

The difference is that the second URL has HTML decoded all & but kept all URL encoded characters.
Using the debugger I found that because the WebBrowser control is misparsing the anchor, I also get wrong values for the 'search' property (of IHTMLAnchorElement) and so on.

Is it a bug ? What can I do to deal with this problem and get a perfectly parsed URL ?

Control DLL and resx files problems

Hi,

I've created an "DLL" to place some controls of my own, but when I "include" them in a normal app ( I inherit a control to my own control), then it gives me the following error:

"The Item xxxx.resx does not exist in the project directory, it may have been moved renamed or deleted"

Do I have to import the resource of the base control to my windows form application project ? I think I'm doing something wrong here... Blush | :O

Thanks in advance, greetings

FileSystemWatcher with 98 and ME

From the minimum requirements it seems that FileSystemWatcher does not work with 98 or ME. So, I'm thinking about writing my own version that does. Any ideas? I guess detecting new files or files that have changed with different sizes is easy. How about detecting changes in files where the new and old file size is the same? Is checking the various date stamps the only way?

Thanks in advance
Andy

Regex pattern

9-Feb-03 21:38

Hi
need some serious help with a regex pattern..

i have the following expression:
Regex regex = new Regex(@"(^(aa)*(?!a)(b))", RegexOptions.ExplicitCapture);

what it does (partially) and is intended to do is to match only when there is an EVEN number of A infront of B

like:

b -> match
ab -> no match
aab -> match
aaab -> no match
aaaab -> match
aaaaab -> no match

etc..

so far so good Smile | :)

what i want is to make it only return the "b" when a match is found.
and also i want it to behave the same way when there is text infront of the pattern , like:

helloB -> match
helloAB -> no match
helloAAB -> match
helloAAAB -> no match

anyone?

Check out the following MSDN sample:

http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/001/830/msdncompositedoc.xml[^]

All you need to do is download the compiled sample which includes a setup.exe file and a settings.ini file. Using VS.NET create a .MSI install file. Then point the settings.ini to your msi file and the .net installer.

There is a step by step guide here:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetdep/html/vsredistdeploy.asp[^]

10/2 = 2.0

You can do a modulus operation to find out if the remainder is 0:

10%2 = 0 (10/2 = 5 r 0)
10%6 = 4 (10/6 = 1 r 4) <-- not a whole number

TrackpopupMenu(Ex) problem

Thomas Caudal9-Feb-03 2:32

Thomas Caudal

9-Feb-03 2:32

I try to display the shell context menu of a file. When I get the
IContextMenu, I want to track the selected menuitem with the
TrackPopupMenu API call.

Here's the call :

int num = TrackPopupMenu(<br />
    menuHandle, // Handle of the menu<br />
    TPM.TPM_RETURNCMD | TPM.tpm,<br />
    pos.X, pos.Y,<br />
    handle, // Handle of my form<br />
    IntPtr.Zero);

The declarations :

public enum TPM :long<br />
{<br />
    TPM_LEFTBUTTON     = 0x0000L,<br />
    TPM_RIGHTBUTTON    = 0x0002L,<br />
    TPM_LEFTALIGN      = 0x0000L,<br />
    TPM_CENTERALIGN    = 0x0004L,<br />
    TPM_RIGHTALIGN     = 0x0008L,<br />
    TPM_TOPALIGN       = 0x0000L,<br />
    TPM_VCENTERALIGN   = 0x0010L,<br />
    TPM_BOTTOMALIGN    = 0x0020L,<br />
    TPM_HORIZONTAL     = 0x0000L,<br />
    TPM_VERTICAL       = 0x0040L,<br />
    TPM_NONOTIFY       = 0x0080L,<br />
    TPM_RETURNCMD      = 0x0100L,<br />
    TPM_RECURSE        = 0x0001L,<br />
    TPM_HORPOSANIMATION = 0x0400L,<br />
    TPM_HORNEGANIMATION = 0x0800L,<br />
    TPM_VERPOSANIMATION = 0x1000L,<br />
    TPM_VERNEGANIMATION = 0x2000L,<br />
    TPM_NOANIMATION     = 0x4000L,<br />
    TPM_LAYOUTRTL       = 0x8000L,<br />
}<br />
[DllImport("user32.dll", SetLastError=true)]<br />
public static extern int TrackPopupMenu(<br />
    IntPtr hmenu,<br />
    TPM fuFlags,<br />
    int x,<br />
    int y,<br />
    IntPtr hwnd,<br />
    IntPtr rect);

The menu is always displayed on the left side only even if the x value
is greater than 0...

Note that I know that the declaration of the API call is false :
normally, there is a "int res" between the y and the hwnd parameters.
But when I add "int res", the menu is no more displayed.

I also tried to use TrackPopupMenuEx but the menu is also not showed...

I have Windows XP Pro SP1.

Thank you
