Hi Martin,

Thanks for the reply.

Control class has a "protected" property called Events which I can't use in my code(which is a Outlook addin)becoz I am using CommandBarButton.

Hello,

Don't care!
I now tested it with an inherited Control, and found out, that it would not fit your needs.

All the best,

Martin

No there isn't. You can't set an event to be null or something for example, which is strange because it is initialized to be null. Here's my way of going around it:

public event EventHandler ExampleEvent;

        public void UnHook()
        {
            Collection<EventHandler> ExampleHandlers = new Collection<EventHandler>();

            foreach (Delegate d in this.ExampleEvent.GetInvocationList())
                ExampleHandlers.Add(d as EventHandler);

            foreach (EventHandler e in ExampleHandlers)
                this.ExampleEvent-= e;
        }

I don't know if there's a better way for this, but this works for me...

Standards are great! Everybody should have one!

Can anyone explain why EditorAttribute is sealed, whilst DisplayNameAttribute isn't ?

I've no desire to base anything on the latter, but I would like to add some stuff to the former, as things stand I have two attributes, EditorAttribute and MyEditorAttribute, when one would suffice if I could inherit from EditorAttribute.

This is way too big a question. Do you have some sort of design? What problems are you facing?

Don't take this the wrong way, but this is not the place to give your requirements and get a complete app in return.

Is the data already in sql server? If not figure out how to get it in there :P

Then give each bit of content keywords and properties to assist in finding relevant info.

Use Full Text Indexing to allow search of body's of text.

Understanding SQL Server Full-Text Indexing
[^]

If you want caching then cache the results for a set period of time.

For spell checking and stuff like that you can use soundex and double metaphone, to find similar words using phonetics and letter similarity.

Beyond this you need to research, experiment and just try stuff to see what works. If you have any specific (i.e. not stuff like "what should my database look like?" but stuff like "why isn't this stored procedure working?") problems come back and we'll be happy to help Smile | :)

I am not sure you are using the application block ui. In the UI its pretty straight forward.
Go to:
Application Configuration-> Logging Application Block -> Trace Listeners
In there add a new Flat File TraceListener.
It give a file name option.

The XML will look something like below:
<listeners> <add filename="trace.log" header="----------------------------------------"
="" footer="----------------------------------------" formatter="" listenerdatatype="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.FlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" traceoutputoptions="None" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.FlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null" name="FlatFile TraceListener">
<add source="Enterprise Library Logging" formatter="Text Formatter"

[Solved] Is it possible to force columntype in the datagridview, for a given object property, when using databinding? [modified]

Larantz4-Jul-07 20:44

Hi guys.

I'm currently working on a datagridview which is bound up to a bindinglist containing a custom display class. The grid already contains ImageColumns for displaying the Icon properties which works properly, only that sorting on them isn't quite what we expected.

The previous programmer implemented a sortalgorithm where sorting on an DataGridViewImageColumn, for Icon type properties, would result in actually using another TextboxColumn containing numeric values for the sort part. But this isn't generic enough as all ImageColumns are sorted for the same numeric value...

So I thought I'd replace the Icon properties for the value objects with IconWrappers containing an icon and a sortable value, and make custom IconWrapperCell and IconWrapperColumn types inhereting from DataGridViewImageColumn and DataGridViewImageCell, and insert these into the DataGridView for the columns that the bindinglist create for the IconWrapper properties.

This seems to be close but no sigar. The bindinglist fails to insert the value into the new columns even though the columnname is identical. OnPaint method for the IconWrapperCell keeps trying to paint with value = null, and if I force the value to be an icon, that icon isn't drawn either.

Has anybody tried anything like this?
I'd really appreciate some feedback if anyone knows anything about replacing/forcing columnstypes for bindinlist created columns.

-- modified at 4:51 Thursday 5th July, 2007

Found a workaround to my problem.
Didn't solve the jigsaw for replacing bindinglist created columns,
but replaced the Icon properties for the value objects with Image type and
used the Image.Tag property for storing sortable values.

The installer is also the uninstaller. Once you've installed the app, you can go to Add/remove programs and uninstall it.

What on earth does that mean? You, as the developer, create an installer and give it to your user.

Just as he runs the setup file to install the program, he has to use the Add/remove programs applet to uninstall it. I really, really don't understand what you want.

sorry i don't know the solution either. But i really liked your comment and i would like to develop an uninstaller.exe too. It's quite a hazard to go to control panel every time i need to uninstall a sw. Specially it is disgusting for developers who need to test their project again and again.

Hope someone can give a solution.... i believe many people like me, will be happy to find a proper solution...
