If the property is and integer you can't do this directly.
What you can do is multiply by 10: 10, 15,20, 25 etc. but it will interfere with any numeric labels you might have obviously.

HI All,
I'm trying to set up the Unity block and I'm getting the following error:
"Given assembly name or codebase was invalid"
My setup is as follows:
private void btnUnity_Click(object sender, EventArgs e)
{
IUnityContainer container = new UnityContainer();
var section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");
section.Configure(container);
var transform = container.Resolve<ILabTest> "AddNewLabTest");
}
The App.Config is:
<unity>
<containers>
<container>
<types>
<type type="Interfaces.ILabTest, Interfaces" mapTo="DTO.LabTest.AddNewLabTest, DTO.LabTest" name="DTO.LabTest"/>
</types>
</container>
</containers>
</unity>
Any help would be appreciated. Thanks!

Can you please update your question, it is hard to read, especially the config. Use the "code button" to highlight both the code and XML.
I'm just checking the obvious here:
Is the dll that contains the concrete class included in the project?
Does
AddNewLabTest implement
ILabTest
Both Interfaces.ILabTest.dll and DTO.LabTest.AddNewLabTest.dll exist in the target bin folder - if not everything will fail.

Hi KEith,
I tried the format buttons for code and markup and got the same result. The dll that contains the concrete class is included in the project. I'm not sure I have the namespace portions of the type tag correct. In the first part I have the type of interface and I'm not sure what the second portion is used for. Then in mapTo attribute I have the concrete implementation, the full namespace path to the concrete method and the namespace without the concrete method.
Thanks,
Bill

This is probably the problem, it makes the most sense. In general
<register type="XXXXX" mapTo="YYYYY, ZZZZZ"/>
XXXX - The name of the interface you want to map from.
YYYY - Type name
ZZZZ - The Assembly name
Lets Say you have an interface IFoo, which is implemented in a class with a name Bar, in namespace MyNamespace contained in Baz.dll:
<register type="IFoo" mapTo="MyNamespace.Bar, Baz"/>
Often the the namespace and the dll name are the same, but not always.

Hi Keith,
Still no luck. In your example I don't see the second portion of the type or a name attribute. Here is what I have right now:
<type type="Frankenstein.Laboratory.Interfaces.ILabTest, Frankenstein.Laboratory.Interfaces" mapTo="Frankenstein.Laboratory.DTO.LabTest.AddNewLabTest, Frankenstein.Laboratory.DTO.LabTest" name="FrankensteinFramework"/>

Not the tag name should be "register", not "type" I assume this is a copy and paste error (I did this in my last post - apologies).
Type definitions have a standard format in .net:
"TypeName, [Assembly], [OtherStuff]"
I usually fully-qualify the typename (i.e. prefix it with the namespace), I don't think this is strictly necessary if the type is in the executing namespace. The stuff in "[]" is optional, you only need [assembly] if the type is not in the executing assembly IIRC (I always specify it any way) though the other stuff isn't relevant right now, for completeness you can specify something like:
"System.Diagnostics.TextWriterTraceListener, System, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
Defines TextWriterTraceListener type in namespace System.Diagnostics. The Assembly containing the defined type is System.dll, st version 1.0.3300.0 having the neutral culture and can be verified with the supplied public key (to verify it is genuine). This definition format can apply to both your type attribute and <creadode>mapTo attribute.
Reading from your code you need to check:
Interface:
Frankenstein.Laboratory.Interfaces.dll (from the second part of the type) exists in the bin directory
Frankenstein.Laboratory.Interfaces.dll Contains an interface ILabTest in namespace Frankenstein.Laboratory.Interfaces (from the first part of type).
Mapped To Type:
Frankenstein.Laboratory.DTO.LabTest.dll (from the second part of the mapTo) exists in the bin directory
Frankenstein.Laboratory.DTO.LabTest.dll Contains an class AddNewLabTest in namespace Frankenstein.Laboratory.DTO.LabTest (from the first part of mapTo).AddNewLabTest must implement the above interface.
General:
The projects or dlls containing your mapped types need to be referenced in the project
The name is really just an identifier. Strictly you don't need it as you can use a default mapping.
What you have looks right, but without the actual project in front of me it is hard to tell. You might want to look at this article, which sets up a basic mapping step by step: http://netpl.blogspot.co.uk/2011/11/unity-application-block-is-lightweight.html[^]

Hi Keith,
I got the config setup from an example I found online, that seems to work. All my interfaces are implemented. Everything is in the same dll FrankensteinFramework.dll. Inside it I have a namespace for Laboratory called Frankenstein.Laboratory.Interfaces. Inside there I have a method called IAddNewLabTest.
The concrete implementation is done in Frankenstein.LAboratory.DTO namespace, in the method AddNewLabTest, which implements the interface. I'm still getting the same error. I've tried a number of things and can't seem to get this working.
Thanks,
Bill

Try:
<register type="Frankenstein.Laboratory.Interfaces.ILabTest, FrankensteinFramework" mapTo="Frankenstein.Laboratory.DTO.LabTest.AddNewLabTest, FrankensteinFramework" name="FrankensteinFramework"/>
Note that name defines the name of the mapping not the assembly, it is possible to resolve more than one type to more than one interface, name is used to disambiguate.
Hopefully the above should work, I think it is right given your description of the file/class structure. Setting these things up for the first time are always a PITA.

Amen to PITA my brother. I made the changes and still getting the same error:
{"The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)":null}. I'm assuming that the issue is in the config. Maybe I'm missing something else. My code errors on :
IUnityContainer container = new UnityContainer();
var section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");
section.Configure(container);
var transform = container.Resolve<ILabTest>("AddNewLabTest");
I did see that the MApToName, TypeName and Name were all populated correctly in the Registrations section of my Unity configuration section object. Am I barking up the wrong tree?

Nope. The line you quote is where the the type information is loaded which is consistent with what you've said in terms of errors. Something is probably wrong with the type definitions , without having access to the project it is hard to tell what though.
One thing that is a common gotcha is that you need to reference all dependant assemblies as well, let's say FrankensteinFramework references Log4Net.dll, then you'd have to reference Log4Net.dll plus all its dependancy tree too. Not doing this won't cause a compile time error (one of the drawbacks of DI) so it'll build even though you don't have the references you need.
The final thing (OT, this isn't your current problem) is that, given:
<register type="Frankenstein.Laboratory.Interfaces.ILabTest, FrankensteinFramework" mapTo="Frankenstein.Laboratory.DTO.LabTest.AddNewLabTest, FrankensteinFramework" name="MappingName"/>
you need:
var transform = container.Resolve<ILabTest>("AddNewLabTestMappingName");
You'll hit this if (hopefully when) you get any further. It also illustrates what the name is for.
[Edit]
Corrected some of the very poor English wot I wrote.

Well I got it working. It's Miller time. This did the trick:
Thanks a ton for your your help!
There's a neat project that demos this at:
http://www.codeplex.com/Download?ProjectName=unity&DownloadId=40036[^]
<unity>
<typeAliases>
<typeAlias alias="LabTestInterface" type="Frankenstein.Laboratory.Interfaces.ILabTest, FrankensteinFramework"/>
</typeAliases>
<containers>
<container>
<types>
<type type="LabTestInterface" mapTo="Frankenstein.Laboratory.DTO.LabTest, FrankensteinFramework" name="FrankensteinFramework"/>
</types>
</container>

Hi,
I am trying to upload a file from my laptop to remote development server. It keeps coming back with either 404 error or 405 error. I am able to download a file with no issues at at all.
all I have is a form with a button on it, and clicking on button invokes the below.
I get the message, "Upload Complete" but the file does not exist on the remote server.
private void button3_Click(object sender, EventArgs e)
{
WebClient wcUpload = new WebClient();
NetworkCredential myNwc = new NetworkCredential("username", "password");
wcUpload.Credentials = myNwc;
wcUpload.UploadFile("http://<dev server>:85", "POST", "C:\\projects\\ProgressBar\\file_0122.csv");
MessageBox.Show("Upload complete!!");
}

What page are you uploading to? Default.aspx?
Is it a 404 or a 405? One would mean your page doesn't exist, the other would mean your "POST"-ing something that expects a "GET" (or the other way 'round, I keep forgetting)

Thank you for your reply.
I am just trying to upload a simple .csv file from my project.

So I noticed. Again, to which asp-page (the one with the upload-control)? Default.aspx?
And, is it a 404 or a 405-error? They're kinda different, so you'd better check.

The "Upload complete" doesn't mean a thing it'll only not show if something throws an error beforehand. UploadFile only thows in the following circumstances:
- The Address or Filename being null
- The URI formed by combining BaseAddress, and address is invalid.
- fileName is null, is Empty, contains invalid characters, or does not exist.
- An error occurred while uploading the file.
- There was no response from the server hosting the resource.
- The Content-type header begins with multipart.
None of which apply to your code. You might get better explanation of what is happing by reading the returned byte array:
byte[] responseArray = myWebClient.UploadFile(....);
string response = System.Text.Encoding.ASCII.GetString(responseArray)
In any case, it looks like the server won't allow posts to the root which is why you are getting the 405. It might also be worth checking something is listening on port 85, and it isn't being blocked by a firewall.

Since there is no single method to do this acrossed all browsers, you're going to have a rather difficult time doing this.

Hi everyone
I am a novice on C# and please tell /redirect me how can I use menu strip control to make a tab control. The tab control provided in C sharp has very limited capabilities in terms of customisation and its text cannot be aligned vertically when its tab strip is vertically aligned.
