Hi,

On adding a web part if in a page at times it throws error and we need to access the page and remove that web part.

To do so we need to add the following querystring to the page url

http://localhost/Pages/Home.aspx?contents=1

It will open the page and will present the list of web parts in the page from wherein we can select and delete the web part that was causing the error.

Hope it helps..

We were using SharePoint:DateTimeControl
in one of our Application Pages in SharePoint. The control returns current date time for SelectedDate if no date is selected.

To check for this we can use IsDateEmpty property.

Just sharing a sample script that we are using to create a web application and a site collection of type publishing in it.

 

# SharePoint cmdlets
Add-PsSnapin Microsoft.SharePoint.PowerShell</pre>
# Set variables
$WebAppName = "MyAppPool"
$WebAppHostHeader = "servername"
$WebAppPort = "portnumber"
$url = "http://servername"
$WebAppAppPool = "MyAppPool"
# This User has to be a Sharepoint Manager Account
$WebAppAppPoolAccount = "domain\username"
$AuthenticationMethod = "NTLM"
$ap = New-SPAuthenticationProvider -UseWindowsIntegratedAuthentication -DisableKerberos

# Create a new Sharepoint WebApplication
New-SPWebApplication -Name $WebAppName -Port $WebAppPort -HostHeader $WebAppHostHeader -URL $url -ApplicationPool $WebAppAppPool -ApplicationPoolAccount (Get-SPManagedAccount $WebAppAppPoolAccount) -AuthenticationMethod $AuthenticationMethod -AuthenticationProvider $ap

# Set variables
$SiteCollectionName = "MySiteCollection"
$SiteCollectionURL = "http://servername:portnumber/"
$SiteCollectionTemplate = "BDR#0"
$SiteCollectionLanguage = 1033
$SiteCollectionOwner = "LSS\lssspadmin"

# Create a new Sharepoint Site Collection
New-SPSite -URL $SiteCollectionURL -OwnerAlias $SiteCollectionOwner -Language $SiteCollectionLanguage -Template $SiteCollectionTemplate -Name $SiteCollectionName

Hope it helps ..

Hi,

We were getting the following error that “list doesn’t exist in the site” because the user was not having read permission on that list.

The code we were using was

SPList myList= spWeb.Lists[“mylist”];

A better approach would be

SPList myList = spWeb.Lists.TryGetList(“myList”);

If(myList != null )

// …

Bye ..

Hi,

We recently had a requirement to create a web part that would be used to update user profile picture and few other properties.

For this we used the FIileUpload control.

The code used

public void UploadPhoto(string accountName, byte[] image)
 {

string loginNameForProfile = accountName.Substring(accountName.IndexOf(@"|") + 1);

if (profileUpload.HasFile)
 {
 SPSecurity.RunWithElevatedPrivileges(delegate()
 {
 using (SPSite site = new SPSite(SPContext.Current.Site.Url))
 {
 SPServiceContext serviceContext = SPServiceContext.GetContext(site);
 UserProfileManager userProfileMgr = new UserProfileManager(serviceContext);
 ProfilePropertyManager profilePropMgr =
 new UserProfileConfigManager(serviceContext).ProfilePropertyManager;

// Retrieve all properties for the "UserProfile" profile subtype,
 // and retrieve the property values for a specific user.
 ProfileSubtypePropertyManager subtypePropMgr =
 profilePropMgr.GetProfileSubtypeProperties("UserProfile");
 UserProfile userProfile = userProfileMgr.GetUserProfile(loginNameForProfile);

 SPSite mySite = new SPSite(userProfileMgr.MySiteHostUrl);
 SPWeb web = mySite.RootWeb;
 SPFolder subfolderForPictures = web.Folders["User Photos"].SubFolders["Profile Pictures"];

web.AllowUnsafeUpdates = true;

Stream fs = profileUpload.PostedFile.InputStream;

byte[] buffer = new byte[profileUpload.PostedFile.ContentLength];
 fs.Read(buffer, 0, Convert.ToInt32(profileUpload.PostedFile.ContentLength));
 fs.Close();
 int largeThumbnailSize = 300;
 int mediumThumbnailSize = 72;
 int smallThumbnailSize = 48;

 

string accName = accountName.Substring(accountName.IndexOf(@"\") + 1);
 using (MemoryStream stream = new MemoryStream(buffer))
 {
 using (Bitmap bitmap = new Bitmap(stream, true))
 {

 CreateThumbnail(bitmap, largeThumbnailSize, largeThumbnailSize, subfolderForPictures,
 accName + "_LThumb.jpg");
 CreateThumbnail(bitmap, mediumThumbnailSize, mediumThumbnailSize, subfolderForPictures,
 accName + "_MThumb.jpg");
 CreateThumbnail(bitmap, smallThumbnailSize, smallThumbnailSize, subfolderForPictures,
 accName + "_SThumb.jpg");
 }
 }
 string pictureUrl = String.Format("{0}/{1}/{2}_MThumb.jpg", subfolderForPictures.ParentWeb.Site.Url, subfolderForPictures.Url, accName);
 // Change the value of a single-value user property.
 userProfile[PropertyConstants.PictureUrl].Value = pictureUrl;
 imgUserProfile.ImageUrl = pictureUrl;
 // Save the changes to the server.
 userProfile.Commit();

web.AllowUnsafeUpdates = false;
 }
 });

}
 }

public SPFile CreateThumbnail(Bitmap original, int idealWidth, int idealHeight, SPFolder folder, string fileName)
 {
 SPFile file = null;

Assembly userProfilesAssembly = typeof(UserProfile).Assembly;

Type userProfilePhotosType = userProfilesAssembly.GetType("Microsoft.Office.Server.UserProfiles.UserProfilePhotos");
 MethodInfo[] mi_methods = userProfilePhotosType.GetMethods(BindingFlags.NonPublic | BindingFlags.Static);

MethodInfo mi_CreateThumbnail = mi_methods[0];
 if (mi_CreateThumbnail != null)
 {
 file = (SPFile)mi_CreateThumbnail.Invoke(null, new object[] { original, idealWidth, idealHeight, folder, fileName, null });
 }

return file;
 } // end of function
