Wednesday, August 9, 2006 - MSN Presence

While playing around with the 'Presence Info' in Sharepoint I came across this post by Mark Kruger. Having read it I have now added the same presence information to this blog. If you have Office 2003 Pro (SP2) and MSN/Live Messenger is running you should see my presence information next to the title at the top of this page. I won't explain how it works because Mark has already done that.

Friday, July 28, 2006 - Limit file types in list item attachments

To place file type restrictions on list attachments on a per list basis you need to add the OkAttach function from ows.js to the new item and edit item aspx pages for the list in question.

function OkAttach()
{
fileID = FileuploadString + FileUploadIndex;
fileInput = attachmentsOnClient.all(fileID);
filename = TrimWhiteSpaces(fileInput.value);
if (!filename)
{
var L_FileNameRequired_TXT = "You must specify a non-blank value for File Name.";
alert(L_FileNameRequired_TXT);
fileInput.focus();
}
else
{
var L_FileUploadToolTip_text = "Name";
oRow = idAttachmentsTable.insertRow();
RowID = 'attachRow' + FileUploadIndex;
oRow.id = RowID;
oCellFileName = oRow.insertCell();
oCellFileName.className = "ms-vb";
oCellFileName.innerHTML =  filename + "    ";
oCellControl = oRow.insertCell();
oCellControl.className = "ms-propertysheet";
oCellControl.innerHTML = "<.IMG SRC='" + document.all.RectGifUrl.value +
"'> <.a tabindex=1 href='javascript:RemoveLocal(" + RowID + ",\"" + fileID +
"\")'>" + L_Delete_Text + "<./a>";
fileInput.style.display="none";
++FileUploadIndex;
attachmentsOnClient.insertAdjacentHTML("beforeEnd",
"<.input tabIndex=1 type=file class=ms-long name=" +
FileuploadString + FileUploadIndex +
" title=" + L_FileUploadToolTip_text +">");
var theForm = fileInput.form;
theForm.encoding = 'multipart/form-data';
idAttachmentsRow.style.display='block';
ShowPart1();
}
}

Make sure you place the function inside the openning FORM tags and write your restriction code in the top of the ELSE block.

Monday, July 3, 2006 - Display Username

Click here to download a small assembly (wcdisplayusername.dll) that can be used to display the currently logged in user's name, login name or both together.

It has been strong named so you can drop it in your GAC and you will not need to raise the trust level in the web.config file. However you will need to add it as a safe control:
ltSafeControl Assembly="WCDisplayUserName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=638bf0fcc8cd630a" Namespace="WCDisplayUserName" TypeName="WCDisplayUserName.DisplayUserName" Safe="True" /gt

Simply register a tag prefix for it on the sharepoint page (this works on both WSS and SPS pages) you want to use it on like so:
lt%@ Register Tagprefix="xx" Namespace="WCDisplayUserName" Assembly="WCDisplayUserName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=638bf0fcc8cd630a"%gt

Put the control where you want it on the page like this:
ltxx:DisplayName DispOption="un" runat="server" /gt
Valid values for DispOption are:
un to display username
ln to display loginname
ul to display username (loginname)
