Tool for testing and accessing web service (announcement)

Hi,

I want to introduce software that can be useful for work with web service.

Web Service Invoker (WS Invoker) is a tool that can help you to access and debug any web service. It is not important how this web service was made (what programming language was used and what operation system is used to run it), because WS Invoker used pure WSDL definition for work.

If you are web service developer, you can find WS Invoker useful to debug and test web service you developed.

If you are web service consumer, you can use WS Invoker to request any web service. You do not need any other software to query any web service.

You can find all details here - http://www.soft-studio.net

Vyacheslav Pedak

if you derive your own class, then override the WndProc method, check if the message is a scrolling message, then check the WParam proprty, to check which dierection the scroll is in.

protected override void WndProc(ref Message m)
{
   if (m.Msg == 0x115)
   {
      if (m.WParam.ToInt32() == 1)
         //scrolled down
      else
         //scrolled up
   }
   base.WndProc(ref m);
}

for every line that is scrolled, theWndProc message is sent, so if you have a counter of some kind, you can track how may lines the user has scrolled, to work out the position. Big Grin | :-D

i have a control that needs to call a method in the parent form, any ideas how to do this?

i tried setting the form as the parents control using the Parents proprty, and the using this.Parent.Method() but it tries to call Method() from the Control class.

I gave the parent form an interface

class MyForm : Form, ITest

then called that interfaces method, and it worked.

((ITest)thi.Parent).Method();

DotNetBar shortcuts?

Martin D12-Aug-02 1:30

Hi all - i'm currently using DotNetBar v1.0.0.15 and have found that if you add a shortcut to a main menu item (ie Ctrl+O when opening files)
the character 'O' gets added to the currently focused control after the shortcut code is run. This results in my currently focused richtextbox getting an additional character each time i try to open a new document.

I've tried trapping the key events but my shortcut code (an open dialog box)gets processed first before the key event handlers, by which point the Ctrl keys are long since deselected and event handler doesn't fire as expected.
Does anyone know of a reason or fix for this strange behaviour between DotNetBar and currently focused text.
boxes?

Cheers

unload DLL

wb12-Aug-02 0:58

12-Aug-02 0:58

my problem:
I have to port a Project from C++ to C#
there is a DLL, i can load

[DllImport("blabla.dll")]	<br />
public extern static void CancelSearch();<br />
.<br />
.<br />
.<br />

and use it...

and then end the programm BUT there is a deadlock,
cause the FreeLibrary(); is never called
by C# Frown | :(

(if I remove the FreeLibrary(); in C++ then the C++ App hangs too)

any idea how to unload the DLL?

At the command line prompt change to the directory the .dll is registered in and then type the following:

regsvr32 -u blabla.dll

You should get a prompt saying it has been unregistered.

no, the DLL is not registered.. its just a normal DLL ...
it waits till I call the FreeLibrary(); function
.... but I have no idea how to do this in C#

Re: unload DLL

Nick Parker12-Aug-02 11:47

So are you only trying to call the FreeLibrary(); function from this .dll? If so and it is non .NET then you will need to use COM Interop.

Normal DLL's dont use COM, and thus COM-interop will not be useful here.

trying use app domains - put the dll calling code in a sep domain - then when you unload the domain the dll should get unload as well...

As far as i know the dll never gets loaded, u can only call static methods and the dll gets used to perform the function by Interop Services. Any dll (assembly) that gets loaded will be written to the debug console when they are loaded.

What part of the RichEditView do you wish to use? There is a RichEdit Control on the tools panel. You can anchor that so that it cover the entire window and streches as the window is resized.

DataTable.Select vs SQL

manson11-Aug-02 8:32

manson

11-Aug-02 8:32

is there any way to retrieve data from DataTable using regular SQL
statement, especially aggregate funcs like AVG(column) or SUM(column)

looks like DataTable.Select("AVG(column)") doesnt work, because it only uses
the agrument as a filter expr, not SQL

(i dont want to access the source database again using OleDBCommand, because the SQL command involves a few inner joins and it just takes too long)

Look at the "DataColumn.Expression Property" in the help. It shows ways to use Aggregates and "DataView" has more information on filtering and sorting.

Drawing help needed

Hi,

Basically I'm trying to create a "selection rectagle" much like the one on the window's desk top when you click the desktop and move the mouse to select multiple icons.

I've thought of two ways to do this:

1) I'm tried to draw a rectagle as I drag the mouse around on a Form. I can draw a rectagle directly on Form but the problem is that any controls that are on the Form appear OVER the rectangle. -- Is there anyway I can get the rectagle to be on top of ALL the contols on the Form? Or can I create a Graphics region that overlays the Form (and all the controls on the Form) in such a way that this Graphics reagion is the "top most" region/window?

2) For my second attempt I created a UserControl and tried to make its background transparent. But this simply did not work. Is there any way to do this. If so then I could simply resize this control as the mouse moved and that would simulate a "selection area/rect".

OR maybe you have a third approach that I should try ( ? ) Big Grin | :-D

Thanks in advance!

Get a handle to the desktop and draw on that. Don't forget to clip the rectangle to your form window.

It sounds like your drawing on your form, doing an update which shows the rectangle and then the controls are being drawn on top of that. If that's the case, then you need to draw a rectangle using XOR and prevent the form and the controls from updating.
