Ted from Ted's sharePoint blog has written an article about enabling embedded pictures in the "Body" field of a discussion group. He got a question about this from Dave on the MS forum.

Some time ago Lamont Harrington wrote a nice article about SharePoint Web Parts and SqlClientPermission errors. In some cases when you develop custom web parts that connects to a SQL server you may be confronted with a nasty error. This is caused by the .NET Code Access Security (CAS). The following article describes a solution:

I'm always surprised that SharePoint developers do not often use more web part menus instead of adding ToolParts. The user doesn't have to go into edit mode which makes it more user-friendly. This article decribes a method for adding an item to the menu of the web part. The menu of a web part can be found in the upper right corner...

I expect that there are a lot of people who already wrote some knowlegde article about this. But it never hurts to explain it again. When you use Response.Transmitfile for transmitting a file to the client it gets the name of the current aspx file.

So how do you set the default name of the file which is downloaded to the client? It is actually very easy. The following code downloads a word file "rapport.doc" to the client:

string pathFileName = @"c:\documents\rapport.doc";
string fileName = System.IO.Path.GetFileName(pathFileName);

Response.ContentType = "application/msword";
Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.TransmitFile(pathFileName);

I like to use singletons in my applications, especially when i don't want to initialise a class all the time when i need it. The idea behind a singleton class is to get an instance by calling a static member method and not be able to instantiate the class yourself. In that way there will only be one instance of the class during the run of the application...

Mart Muller wrote a great tip about creating alerts programatically:

In some cases you want a user to automatically create alerts on particular lists, for example an action list. It's very easy to achieve that:

SPWeb thisWeb = SPControl.GetContextWeb(Context);
thisWeb.AllowUnsafeUpdates = true;
SPList myList = thisWeb.Lists["ListName"];

// in this case a daily alert on all list actions
thisWeb.CurrentUser.Alerts.Add( myList,SPEventType.All,SPAlertFrequency.Daily);
thisWeb.CurrentUser.Update();

The same way, alerts can be added for list items.

Some weeks ago i wrote an article about creating a birthday webpart. The problem with that webpart is that the list every time has to be updated to refresh the coming birthdays. This is an example of a custom webpart which retrieves its information from a ContactList...


The BirthDay WebPart version 1 is now downloadable. Follow the link:

A SPQuery can be used to retrieve some SPListItems from a SPListItemCollection. The following code is an example which shows how to do a DateTime comparison. It is very important to use a correct date format as the value in the inner xml of the where clause...

I needed some tool to look for keywords, texts or other things by searching through all fields of all columns of all tables of a specific database.

I got a request from the customer to change the background color of a WSS / Portal page depending on the login rights. This example delivers an example which will do this. But the same example can be used to override any other style defined in SPS.css and OWS.css.
