For details of how to initialize the DynaTree, check out the sample code in section 4.1 in DynaTree Documentation

1. You go to Run > “RegEdit” hit enter.
2. Then you find the key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
3. Add a string value to it, name it whatever you want and put the full path to the memcached.exe file into the value of it.

Add memcached.exe to startup in Registry in Windows 2008 Server

Now you should be able to see the memcached startup when you reboot the system.

PS: In case you have a dependent service on memcached, change its start-up type to Automatic(delayed)

if (m.treeListView.InvokeRequired)
{
ra= (ReportData?)m.treeListView.Invoke(new Func<ReportData?>(
() => m.CreateDataforReport(“Rpt type”, false)));
//m is the main form’s reference!

}

So what I’ve done is that I passed the main form’s reference to the child form in the constructor and made the TreeListView and the CreateDataforReport public. Notice that I called CreateDataforReport method inside the Func<ReportData?> and not directly. This is what enables you to get the appropriate return value, be it string, integer or any complex type like I have it here.

The type ‘System.IO.Packaging.Package’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35′

Turns out, all you need to do to fix it is to just add another reference to WindowsBase assembly that is found in the .NET Tab.

Sharepoint 2010 Site Collection Administration

In the beginning I was able to install the web parts being the “Owner” of the site collection BUT NO!! To see those web parts in the SharePoint 2010 site and actually put them to some use, you need to be the “Site Administrator” not just the owner. YEAH RIGHT! Very intuitive!! That thing just cost me some 5-6 hours can you imagine that?! Anyways, I hope it helps relieve the pain of some of you out there.

So all you need to do is to go to the Services section in Control Panel\System and Security\Administrative Tools and look for the service called SharePoint 2010 Administration, it was on manual start up, changed it to automatic and started it and gotten rid of this error. Simple isn’t it!

The location of images in SharePoint 2010 Project/web part

This one is especially useful for the new bie because when you start with building webparts for SharePoint 2010, you often come to a point where you wanna add a URL somewhere, lets say programatically or in the CSS or may be in the ASCX code and you wonder, hey wait a minute where are the images for SharePoint placed anyway? How do I refer to them? So here’s your answer.

What you do is that you Right Click the Web parts project > Add > SharePoint “Images” Mapped Folder option. Doing that will give you an images folder inside your project directory and you can refer to that like this:

“~/_layouts/Images/ProjectNamesETC/xyz.png”

Have fun!

So here’s a sample of the code in the visual webpart that I was writing:-

<SharePoint:SPGridView ID=”spGvWorkOrders”  runat=”server” >
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID=”lbl_workOrderId” Text=’<% # Bind(“Id”) %>’  runat=”server”></asp:Label>
</ItemTemplate>
</asp:TemplateField>

<asp:TemplateField>
<ItemTemplate>
<asp:Label ID=”lbl_workOrderTitle”  runat=”server” Text=’<% # Bind(“Title”) %>’ ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>

<asp:Image ID=”img_status” Width=”10px” ImageUrl=’<% #StatusToImage(“\”"+ Eval(“Status”)+”\”") %>’ runat=”server” />
</ItemTemplate>
</asp:TemplateField>

…

And here is the function:-

protected string StatusToImage(string status)
{
if ( ( rowcount++ % 2) == 0)
return “~/_layouts/Images/WorkOrders/add.png”;
else
return “~/_layouts/Images/WorkOrders/arrow_up_green.png”;
}

Notice that I had been using the Bind function earlier but when I tried using it to send the value to StatusToImage function it did not work. Eval is the better option anyway in case you’re just interesting in displaying the data.

So what I did was that instead of using the event I just put the function call inside the ascx code so that whenever a row is created that function is called with the value of Status from the Data Source and with that value sent to a function, we can return back a string to give the path to the image file. The syntax however, is quite tricky and it took me a while to figure that out correctly but it worked in the end. Hope it will save you some time though!

“An error occurred. More information may be available in the server event log.”

Now it is important to note that the logs being referred to here are NOT the ones at C:\Program Files\Common Files\microsoft shared\Web Server Extensions\12\LOGS because these are the WSS logs.

The logs you need to see are the ones in the Administrative Tools –> Events Viewer. So when I checked that it said

SharePoint Learning Kit Error
System.Data.SqlClient.SqlException: Cannot open database “SharePointLearningKit” requested by the login. The login failed.Login failed for user ‘NT AUTHORITY\NETWORK SERVICE’.

So now I knew that all I need to do is to grant access to the SharePointLearningKit database to the user NT AUTHORITY\NETWORK SERVICE and to do that just fire up SQL Server Management Studio, go to Security node –>Logins –> right click NT Authority\Network Service –> Properties –> User Mappings –> check the database SharePointLearningKit and simply check the db_owner  role for it to give it maximum access for the time being –> Press the OK button and you should be able to see the Web Part now!
