Hi Colin,
You are right. No need to give ToString(). Application.StartupPath is enough.

Hi
I am trying to develope an Utility to handle reporting of errors and exceptions in my application. Whenever an exception occurs I want the exception details to be written to a XML file.
I am using the following code, but it does not append to the file, it overwrites the previous data. How can I have the new exceptions append to the file so that I have a full history of all the exceptions without having to create a new file each time?
private static void LogException_XML(DateTime date, string fullpath, string localPath, Exception e)<br />
{<br />
try<br />
{<br />
XmlWriterSettings settings = new XmlWriterSettings();<br />
settings.Indent = true;<br />
settings.IndentChars = (" ");<br />
using (XmlWriter writer = XmlWriter.Create(fullpath, settings))<br />
{<br />
writer.WriteStartElement("Exception");<br />
writer.WriteElementString("Date", date.ToShortDateString());<br />
writer.WriteElementString("Time", date.ToShortTimeString());<br />
writer.WriteElementString("Message", e.Message);<br />
writer.WriteElementString("Source", e.Source);<br />
writer.WriteElementString("Stacktrace", e.StackTrace);<br />
writer.WriteElementString("TargetSite", e.TargetSite.ToString());<br />
writer.WriteElementString("TargetSite", e.TargetSite.ToString());<br />
writer.WriteEndElement();<br />
writer.Flush();<br />
}<br />
<br />
}<br />
catch (Exception ex)<br />
{<br />
throw ex;<br />
}<br />
}
Thanks.

You could use an overload of the XmlWriter.Create method that takes a Stream instance instead of the filepath and explicitely create a FileStream that appends to the file, but this will create invalid XML since an XML document must have a single root element. I'm not sure how hard it is to position the XmlWriter in a way that you will overwrite the closing root element tag, so I recommend the XmlDocument class.

Dear all,
How would I be able to generate MS project File in C# ?

I've got a remoting based application up and running (basically a client app that uses a custom server to access a database, etc), and it seems to do everything fine as long as the client and server are on the same Windows domain.
Unfortunately it also needs to be used on another domain within the company (both domains can see each other, btw).
When the client application is run on the other network, I get the following exception:
=============================================================================
InvalidCredentialException: The server has rejected the client credentials.
Stack Trace:

=============================================================================
Where do I start in determining what's wrong with the setup, or is this just something I'll have to do differently if the app is going to straddle 2 domains?

Hi!
You could try using a http channel instead of a tcp channel...

I'll give that a go.
I thought I should add the client and server remoting configuration as well:
server:
<channel ref="tcp" port="6792" displayName="TCC Channel (MyServer)" authenticationMode="IdentifyCallers" secure="true" authorizedGroup="Users">
<serverProviders>
<formatter ref="binary" typeFilterLevel="Full"/>
</serverProviders>
</channel>
client:
<channel ref="tcp" port="0" displayName="TCP Channel (MyClient)" authenticationMode="IdentifyCallers" secure="true" authorizedGroup="Users">
<serverProviders>
<formatter ref="binary" typeFilterLevel="Full"/>
</serverProviders>
</channel>
Edit: Damn HTML parsing!

Hello everyone,
I am trying to add the Speech Recognission into my Windows Application. I have added a button which activates the Speech Recognission once it is clicked by assigning two Event Handeler shown bellow:
// Get an insance of RecoContext "Using Shared RecoContext".
objRecoContext = new SpeechLib.SpSharedRecoContext();
// Assign an eventhandler for the Hypothesis Event.
objRecoContext.Hypothesis += new _ISpeechRecoContextEvents_HypothesisEventHandler(Hypo_Event);
// Assign an eventhandler for the Recognition Event.
objRecoContext.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(Reco_Event);
Now I would like to add a button to Disable the Speech Recognission. Can someone be kind enough to tell me how I can do this? I tried the following code in order to release the event handler but it is not doing it.
//code to realease the event handler
objRecoContext = null;
Thank you so much for your help and have a great day.

I thought you could use -= to remove an event handler ?

Hello Christian,
You were correct. I tried it with " -= " and it worked. I must have been on a different planet, mate.
Thank you so much for your help.

Hi All,
I need to write some GUI application in MFC that will be able to support some COM call from other application.
I want to do it in C# beside MFC - but i don't know how can i write in C# and support all logical architecture that i have in COM.
How can i register the application ?
How can i define some call from other application ?
Thanks for any help.

You want to write a C# COM object ? There's a wizard for that, I thought.
Being COM, it will work like any COM app, I'd have thought. Otherwise, it wouldn't be COM.
Your other option is to use C++/CLI to call C# libraries within your MFC app.

Dear All,
If have the following question. I have two forms. On form one I open another form with the following code :
Form f = new Form();<br />
f.ShowDialog();
A new instance of that Form opens. However .. in form B I want to run a method from Form A. I have to reference an object.
FormA a = new FormA<br />
a.Method();
This works fine, however it opens a new instance of FormA and run the method in the new instance, while what I really want it to do is go back to the previous FormA ( already open ) and run the Method on that form.
Any suggestions ?
thx !!

Call the method before you do the ShowDialog
Form f = new Form();
f.Method();
f.ShowDialog();
Hope that helps.

Yes, of course.
You can do two things.
1 - pass the instance of Form1 in to Form2 ( hack )
2 - define a delegate between the two forms, so that calling a method in form2, runs code in Form1.
There are tutorials on how to use delegates on code project.

FormA a;

I use modified Rockford Lhotka excellent SetPropertyValue()
from DataMapper class to load objects from database.
My entity object property names are mixed case.
DataReader returns lower-case only column names.
So SetPropertyValue() cannot map columns to property names.
How to change this code so that it does not depend on the propertyName case ?
public static void SetPropertyValue(
object target, string propertyName, object value)
{
PropertyInfo propertyInfo =
target.GetType().GetProperty(propertyName);
if (value == null)
propertyInfo.SetValue(target, value, null);
else
{
Type pType =
Utilities.GetPropertyType(propertyInfo.PropertyType);
Type vType =
Utilities.GetPropertyType(value.GetType());
if (pType.Equals(vType))
{
propertyInfo.SetValue(target, value, null);
}
else
{
if (pType.Equals(typeof(Guid)))
propertyInfo.SetValue(
target, new Guid(value.ToString()), null);
else if (pType.IsEnum && vType.Equals(typeof(string)))
propertyInfo.SetValue(target, Enum.Parse(pType, value.ToString()), null);
else if (pType.IsEnum && vType.Equals(typeof(decimal)))
propertyInfo.SetValue(target,
Enum.Parse(pType, value.ToString()), null);
else
propertyInfo.SetValue(
target, Convert.ChangeType(value, pType), null);
}
}
}
}
}

You could try to every where you see a ToString() add a .ToLower()
to set the property name to all lower.
The method you posted seems to be where the property value is getting set. I am not sure you can make changes to where the value is getting set to get the property name to make lower case.
Hope that helps.

I have a web application that references an access database in my app_data folder. Locally I can reference the db by C:/My Docs/Visual Studio 2005/Website/My Website/App_Data/myaccess.mdb
My question is, in my code how do I reference the database relatively since I do not know what drive and directories my site will be stored on? I've tried ~/App_Data/myaccess.mdb (tried this locally and it does not reference the db) and it does not connect. All suggestions welcome thanks.

I'm not exactly sure how to incorporate this into my connection string
//create an open string
string conString = @"Provider=Microsoft.JET.OLEDB.4.0;" + @"data source=C:\Documents and Settings\My Name\My Documents\Visual Studio 2005\WebSites\MySite\App_Data\td.mdb";
i've tried
@"data source=" + Server.MapPath("http://www.mywebsite.com/App_Data/td.mdb");
and get an error.
Please advise. Thanks.

|
|
|

The MapPath method takes a virtual path, not a complete url. Use just "/App_Data/td.mdb".

That is way too specific. Could you be a bit more vague, please?
