Hi
I'm trying to do a batch manager, and I use a CheckedListBox to display the status of the jobs, but I want to change the color of every item, there is a way to do it???
Thanks

Extend the CheckedListBox control and override OnDrawItem. In the DrawItemEventArgs passed to the method (and don't forget to call base.OnDrawItem when done), set the DrawItemEventArgs.BackColor to a color based on the checked state of the item (which you can get the index for in DrawItemEventArgs.Index).

Is there anyway to remove/hide the vertical scrollbar in a listbox control?
|
|
|
|
|
You mean ScrollAlwaysVisible property ?

no, that property does not remove the scrollbar. I never want to see the vertical scrollbar, even when i have allot of elements.

If you look at the class member documentation for the ListView, Scrollable should jump out. Set this to false to never show scroll bars.

The listbox control is not the same as the listview or?
|
|

Sorry, I missed that for some reason.
To make a ListBox with no vertical scroll bar (there is a ListBox.HorizontalScrollbar that you can set to false), extend ListBox with your own class and override the CreateParams like so:
public class MyListBox : ListBox
{
private const int WS_VSCROLL = 0x00200000;
protected override System.Windows.Forms.CreateParams CreateParams
{
get
{
System.Windows.Forms.CreateParams parms = base.CreateParams;
parms.Style &= ~WS_VSCROLL;
return parms;
}
}
}That will get rid of the vertical scroll bar. If you want, you could add a VerticalScrollbar that controls whether the WS_VSCROLL is set or unset and then call RecreateHandle after setting it:
public class MyListBox : ListBox
{
private const int WS_VSCROLL = 0x00200000;
protected override System.Windows.Forms.CreateParams CreateParams
{
get
{
System.Windows.Forms.CreateParams parms = base.CreateParams;
if (!this.verticalScrollbar)
parms.Style &= ~WS_VSCROLL;
return parms;
}
}
private bool verticalScrollbar;
public virtual bool VerticalScrollbar
{
get { return this.verticalScrollbar; }
set
{
if (this.verticalScrollbar != value)
{
this.verticalScrollbar = value;
this.RecreateHandle();
}
}
}
}

After a couple of frustrating days, my webservice is still not operational. Since I believe that the error message 'DLL not found (oci.dll)' was not the real problem, but having no ideas of what to try next, I converted my C# code from using the Oracle classes to using the Odbc classes. I'm now getting an HTTP 500 error 'Internal Server Error' when I invoke my web service. Besides the web server log that also indicates this same error, is there any other logging information that I could use to figure out what could be wrong. Thanks for any thoughts (and condolences  ).

Check Context.Trace.Write(). Whiich place a messages in trace.axd file and you can browse it inside your webservice folder.But you have to enable trace tag in your web.config.

Do you mean the TraceContext.Write() method ? 
What I'm after is to get some kind of a 'stack trace' of where things have gone wrong.

I haven''t test method you say. This is what I talk about:
Writing Trace Messages[^]
You can use Context.Trace.Write() method whenever you want, inside try/catch block to write message error in a trace filr.

I understand. That method is for inclusion within an ASP.NET page. In my case I'm looking to put this in my web service and I think I should be using the TraceContext.Write instead. Thanks so for the pointer.

If you mean it doesn't work for WebSerivce, no it works there too. No difference. Trace file exist there too.

It won't work if it doesn't compile. There is no documentation within the .NET Framework for Context.Trace.Write() so how does one use it? The closest I could find was a WebService member called TraceContext.Write().
Still trying to get this data access to work in a web service.

I read the page that I sent its link for you again and it say the things that I told you is the same as TraceContect.Write(),I mean them are the same things. I think you are developing without VS.NET. In that article it is mentioned that how to use it and you can place it in different place of your code for tracing purpose. As much as I understand it can help you.

Hit the nail on the head. I am not using VS.NET. But why should that make any difference to developing web services? Does VS.NET bring extensions to the .NET Framework? My understanding was it gave you an IDE to develop with and a whole whack of wizards to generate code for you.
I'm going to try and use the Oracle data provider as Guillermo has suggested.

What Oracle provider are you using ?
Free your mind...

Oracle Client 9.2 installed. With the error of DLL not found, I was using the Oracle classes that ship with .NET Framework v1.1. With the HTTP 500 error, I was using the Odbc classes that ship with .NET Framework v1.1. For the Odbc test, I was using the Oracle ODBC driver. I was also trying the Microsoft ODBC driver for Oracle, but could even get it to pull data into Excel, so I gave up trying to get it to work.

Seems that few people uses Oracle on CP.
To be honest, I've never used the Oracle Provider that comes with .NET Fw v1.1. Since we start developing an application at work, we used the Oracle Data Provider from Oracle[^], and we only had 1 problem with the assembly. What I did was register the ODP.NET into the GAC (Global Assembly Cache) and everything is fine now.
Why don't you give a try, and use this provider ?
Hope this helps.
Free your mind...

Considering that with my Odbc test I couldn't get the Microsoft driver to even connect to the database, I think this is a fine suggestion. I'd add that I've used the OO4O (Oracle Objects for OLE) product when doing at lot of C++ development and it was out standing to use. Maybe I'll have the same success with the Oracle Data Provider for .NET.
Thanks for idea and I'll let you know the outcome.

Hi Guillermo,
I installed the ODP.NET but was still unsuccessful in getting the service to work. It still HTTP's error 500 Internal server error.
I also converted a console test application to use these classes and the application still tested perfect.
Here's something I don't understand though. Even though the installation of ODP.NET registers the namespace/DLL in the GAC (I confirmed it's existence using the assembly viewer), when compiling either my service or my console programs I must append a reference to the DLL explicityly
csc /t:library /out:C:\Inetpub\wwwroot\bin\ForwardRate.dll ForwardRate.cs /r:c:\oracle\ora92\bin\Oracle.DataAccess.dll Once I specified what namespace I'm using within my source file, I would have expected that if that namespace exists within the GAC, the appropriate DLL reference would not be needed?

Still getting the oci.dll problem ?
Man, this is weird...

Not sure about this, all compilations I've done with ODP, have been using VS.NET.

I'm starting to get that uneasy feeling that VS.NET may be a requirement for doing any serious web service development. The simple stuff using classes straight out of the framework with no extra references seem to work fine. You can build the dll and deploy the service no problem. But as soon as I start to do anything serious and require extra references, it all starts going wrong.
