Hi,

Have you generated the ProjectInstaller class?

It should look something like:

<br />
	[RunInstaller(true)]<br />
	public class ProjectInstaller : System.Configuration.Install.Installer<br />
	{<br />
        ...<br />
        }<br />

Regards

David

Thanks for your reply
Yes, I did write this class, as I have mentioned in my question. The problem is somewhere else but I don't know where...

Uninstall removes files and leaves executable running

Hi,

I have used VS2005 to create a .msi package for my software. The problem though is that when I uninstall the software either through "Add/Remove Programs" or through running the uninstaller again, the uninstaller will remove all of the files but leave the executable running.

Is there anyway to have the Installation project stop the executable, both when the application is in window form and when the application is in the system tray?

Thanks,
Adam

Hi,

you could use a FileWatcher and teach your app to exit gracefully when something
happens to a specific file (rather than an installer trying to kill your process !)

That worked! Thanks for your help...I put a FileWatcher in my application and told it to watch deletion of the .exe. On deletion, then call Application.Exit() and that worked great!

Many thanks,

assign data to object from webservice

I have assigned a variable of type object to a method.
i.e. object o = getDataFromWebService(int intData);

Then hovering over o or looking at the values in Locals Window for o, I can see the data has been returned. Something like:
o[0]
o[1]
o[2]
etc...
Theh for each index, in the locals window I can see the fields returned also.

In code, how can I refer to these values please?
I tried something like:
string x = o[0].ToString();
but I get this errorL:
Cannot apply indexing with [] to an expression of type 'object'

Thanks

Cast the object to the appropriate class. I can't tell you what that is because you have not supplied sufficient information.

I actually want to open Notepad on a remote machine.

By writing the following code, I am able to run it, but the problem is that it is runs in background. I can only see it by opening up the windows task manager of the remote machine.

ConnectionOptions objConnectionOptions = new ConnectionOptions();<br />
objConnectionOptions.Impersonation = ImpersonationLevel.Impersonate;<br />
objConnectionOptions.EnablePrivileges = true;<br />
objConnectionOptions.Username = strUserName;<br />
objConnectionOptions.Password = strPassword;<br />
ManagementScope objManagementScope = new ManagementScope(@"\\remote-computer-name\ROOT\CIMV2", objConnectionOptions);<br />
objManagementScope.Connect();<br />
<br />
ManagementClass processClassFinal = new ManagementClass(objManagementScope, new ManagementPath("Win32_Process"), null);<br />
ManagementBaseObject inParamsFinal = processClassFinal.GetMethodParameters("Create");<br />
inParamsFinal["CommandLine"] = @"c:\windows\notepad.exe";<br />
ManagementBaseObject outParamsFinal = processClassFinal.InvokeMethod("Create", inParamsFinal, null);

Is there anyone who could help me in sorting out this problem

Thanks.

Hi.

Where and where from exactly do you want to load a file?
For example, loading to Bitmap you can do like this:

Bitmap bmp = Bitmap.FromFile("C:\\image.jpg");

And you can use it for example to set your Form BackgroundImage property:

this.BackgroundImage = bmp;

This looks a bit wierd with all those escaped backslashes and quotation marks, but it works fine for me:

javascript:WebForm_DoPostBackWithOptions\(new WebForm_PostBackOptions\(\\\"([^\"]*)\\\", \\\"([^\"])*\\\", (true|false), \\\"([^\"]*)\\\", \\\"([^\"]*)\\\", (true|false), (true|false)\)

or a little different version:

javascript:WebForm_DoPostBackWithOptions\(new WebForm_PostBackOptions\(\\\"(.*)(\\\")??, \\\"(.*)??\\\", (true|false), \\\"(.*)??\\\", \\\"(.*)??\\\", (true|false), (true|false)\)

validating xml file in .net2.0

cellardoor07161-Mar-07 2:58

1-Mar-07 2:58

I´m trying to validate a xml file against schema... I had to migrate my code from .net 1.1(where I was using XMLValidatingReader and it was working just fine...) to .net 2.0. The XMLValidatingReader became obsolete, so I tried the XMLReader instead, but I always get only the first error... Here is my sample code:

private void validate()
{
XmlSchemaSet xsc = new XmlSchemaSet();
xsc = this.getSchemaToValidate();

XmlReaderSettings xs = new XmlReaderSettings();
xs.ValidationType = ValidationType.Schema;
xs.ValidationFlags = XmlSchemaValidationFlags.ReportValidationWarnings;
xs.ValidationEventHandler += new ValidationEventHandler(ValidationCallback);
xs.Schemas.Add(xsc);
fs = new FileStream("XMLTest.xml", FileMode.Open, FileAccess.Read, FileShare.Read);
XmlReader vr = XmlReader.Create(fs, xs);

while(vr.Read()) {}
}

private void ValidationCallback(object sender, ValidationEventArgs e)
{
tbErrorMessage += e.Message + Environment.NewLine;
this.numberOfValidationErrors++;
}

Can anyone help me with this?

Have you considered XmlDocument. In 2.0:

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(xmlFile);
xmlDocument.Schemas.Add(xmlSchema);
xmlDocument.Validate(validationHandler);

Seems simpler.

I can´t use XmlDocument because my xml files are too big(about 80MB) and I don´t want to load the whole xml into memory... I have to read them sequencially, that´s why I use XmlReader.

I can't tell you - tried a quick test with code identical to yours except that I used Schema rather than schema set and got multiple errors.

Good Luck!

It looks very similar like examples from MSDN. I am surprised it doesn't work....

I don't really have much experience with "new" xml classes in .NET 2.0 , but did you consider XmlSchemaValidator[^]?
