In .NET Framework 2.0 the attribute configSource was added to several elements of the .NET config files so you could use external files.
Sadly those attribute are not available for the system.serviceModel.However I found this post that shows a interesting workaround.
You can modify your serviceModel file to look like this:
<configuration>
<system.serviceModel>
<services configSource="Services.config" >
</services>
<bindings configSource="Bindings.config">
</bindings>
<behaviors configSource="Behaviors.config">
</behaviors>
</system.serviceModel>
</configuration>
And then you can put your configuration settings in separate files like the following:
Behaviors.config
<configuration>
<system.serviceModel>
<services configSource="Services.config" >
</services>
<bindings configSource="Bindings.config">
</bindings>
<behaviors configSource="Behaviors.config">
</behaviors>
</system.serviceModel>
</configuration>

If you ever get an error like, it is an annoying situation where the web server is trying to use and old compilation of your aspx files.
The workaround I have is: rename web.config to stopweb.config.
Browse to the offending page URL it will return an error. After you receive the error rename stopweb.config to web.config
Browse to the offending page. This will force the server to compile the web pages.
And if it work the problem will now go away.
ASP.NET has gone a long way. And it might be the right time to start moving your sites to ASP.NET.
But what happens if you have a big investment in JSP. Will I lose all my JSP skills?
Well ASP.NET is not the same as JSP but the MVC view engine concept can help you retain some of the JSP flavor.
A good MVC View Engine project is SharpTiles this project provides a partial implementation of JSTL and Tiles.
Just take a look at the the SharpTiles. Just as they say SharpTiles if for you if “You are a Java Developer and you don’t like .aspx”
I you were looking for a way to do that just take a look at this post: http://weblogs.asp.net/whaggard/archive/2004/08/30/223020.aspx
Just notice that for this post you need to add this struct:
[StructLayout(LayoutKind.Sequential)]
public struct SHFILEINFO
{
public IntPtr hIcon;
public IntPtr iIcon;
public uint dwAttributes;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 260)]
public string szDisplayName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 80)]
public string szTypeName;
};
During a Silverlight migration project from VB6 I was trying to add a WCF reference,
everything seemed to work in the wizard but no code was generated.
After reviewing the Warning messages, i found that some said:
Custom tool warning: Cannot import wsdl:portType
What I did to solve this issue?
1. Right click on your service reference
2. Select Configure Service reference
3. Uncheck the option that says Reuse types in referenced assemblies.
4. Press OK
After that VS generated the code and I could use the WCF service.
Microsoft Access was (and is still) very used for simple data entry applications.
But Microsoft Access despite all its good is kind of an old technology and there was
no clear alternative for a simple mortal development environment… until Microsoft Lightswitch.
This series of posts illustrates the experiences of migrating Microsoft Access applications to LigthSwitch.
This post shows the result of migrating all Northwind Access example tables:
The following is Microsoft LightSwitch Solution explorer showing all Tables
And these are some of the Northwind tables in LIghtswitch
The migration process is straightforward. Text and Memo fields can be migrated to string, Numbers can be migrated to Int32 or Int64, Currency is map to Money. Yes\No can be mapped to boolean with a Value List.
There is support for specifying a caption (Display ID in Lightswitch), Description, and validation rules.
I will keep posting about Query migration, form migration and also report migration. Stay tuned.
I had a Windows Server 2003 and I was trying to connect to Oracle with the System.Data.OracleClient provider.
I was able to connect from a console application but not from ASP.NET.
From ASP.NET I only got ORA-12154 errors.
I found that on Windows 2003 Server, ASP.NET applications run in the
security context of the “Network Service” user.
So I tried these two things:
I first started following these steps:
1. Log on to Windows as a user with Administrator privileges.
2. Launch Windows Explorer from the Start Menu and and navigate to the
ORACLE_HOME folder. It is usually under the oracle instalation folder.
In my case that is C:\oracle\product\10.2.0\client_1
3. Right-click on the ORACLE_HOME folder and choose the "Properties" option
from the drop down list. A "Properties" window should appear.
4. Click on the "Security" tab of the "Properties" window.
5. Click on "Authenticated Users" item in the "Name" list (on Windows XP
the "Name" list is called "Group or user names").
6. Uncheck the "Read and Execute" box in the "Permissions" list under the
"Allow" column (on Windows XP the "Permissions" list is called
"Permissions for Authenticated Users").
7. Re-check the "Read and Execute" box under the "Allow" column (this is
the box you just unchecked).
8. Click the "Advanced" button and in the "Permission Entries" list make
sure you see the "Authenticated Users" listed there with:
Permission = Read & Execute
Apply To = This folder, subfolders and files
If this is NOT the case, edit that line and make sure the "Apply onto"
drop-down box is set to "This folder, subfolders and files". This
should already be set properly but it is important that you verify this.
9. Click the "Ok" button until you close out all of the security properties
windows. The cursor may present the hour glass for a few seconds as it
applies the permissions you just changed to all subfolders and files.
10. Reboot your computer to assure that these changes have taken effect.
(I thought that rebooting was not that important but it seems that you have to reboot to make changes effective)
It sometimes happens that it is not enough, because it seems that some oracle installations need the
the ASP.NET process to run with an account with sufficient privileges.
The second thing you can do in that case is.
1. First open the machine.config file. That will be usually in %windir%\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config
2. Look for something like:
<system.web>
<processModel autoConfig="true" />
3. Add the userName=”System” attribute. For example
<processModel autoConfig="true" userName="System" />
4. Restart the IIS.
I have a silverlight application that I was trying to publish from Visual Studio to my local IIS and I got this problem:
For the record I have Windows 7.
So you can write on the Search program and Files “ Turn Windows Features on or off”
And then select
If you are doing Silverlight development, one thing that can be cumbersome is keeping in sync
your development and production settings. Specially if you are using WCF services because you have
to make sure that your ServiceClient.config file has the right values.
What I usually do is this.
1. First set fixed ports for my application. See http://blogs.msdn.com/b/webdevelopertips/archive/2008/11/07/tip-21-did-you-know-how-to-set-a-fixed-port-for-the-developer-web-server.aspx
2. Modify my hosts file in C:\Windows\System32\drivers\etc adding an entry like:
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost
127.0.0.1 productionserver.cloudapp.net
In this way all you have to change is your hosts file and you keep the same settings for development and for production
One obvious thing in modern symbian mobiles, is how to detect orientation.
I am currently porting some Silverlight 1.0 samples like GrandPiano to Silverlight for Symbian and I was wondering
how can I detect the phone orientation. Well I just analysed the Bing demo and find out that is kind of simple.
What you need is something like this:
public static readonly DependencyProperty OrientationProperty =
DependencyProperty.Register("Orientation", typeof(Orientation), typeof(Page),
new PropertyMetadata((Orientation)0, new PropertyChangedCallback(OrientationPropertyChanged)));
private static void OrientationPropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
(sender as GrandPiano).UpdateOrientation();
}
private void UpdateOrientation()
{
base.Width = (this.Orientation == Orientation.Vertical) ? DeviceVerticalSize.Width : DeviceVerticalSize.Height;
base.Height = (this.Orientation == Orientation.Vertical) ? DeviceVerticalSize.Height : DeviceVerticalSize.Width;
base.Clip = new RectangleGeometry { Rect = new Rect(new Point(), new Size(base.Width, base.Height)) };
}
// Properties
public Orientation Orientation
{
get
{
return (Orientation)base.GetValue(OrientationProperty);
}
set
{
base.SetValue(OrientationProperty, value);
}
}
