Hi,

In a Visual Web Part we were saving few values in a hidden input field and were retrieving it in the jScript. However the issue we were facing was the id of the control kept changing.

http://therightstuff.de/2006/02/14/Accessing-Controls-In-SharePoint-Web-Parts-Using-JavaScript-On-The-Client-Side.aspx

Here the clientidmode property came to rescue.

<input id=”hiddenobject” type=”hidden” clientidmode=”Static” runat=”server”/>

With the clientidmode set as static the id remains the same.

Hope it helps.

Got this error while adding web part to one of the pages in SharePoint. It was all working fine earlier.

 

After much struggle, realized that the LiveVewWebPart.webpart had the incorrect namespace specified.

Correcting it resolved the issue.

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

Hi,

At times we need to disable wsstracing.exe to improve the system’s performance at it uses too much CPU resources.

Open Command Prompt as Administrator

To Disable

• sc stop “SPTraceV4”
• sc config “SPTraceV4” start= disabled

To Delete

• sc delete “SPTraceV4”

bye.

Hi,

We recently had a requirement to hide the Personalize this Page option from the SharePoint Site for all the users.

The way we can do it is by commenting out the following element in the Welcome.ascx page

(\15\TEMPLATE\CONTROLTEMPLATES\Welcome.ascx)

The other option through central administration

Hope it helps.
