JavaScript document.write doesnot work in XMLI was working with an XML file which had spit out HTML . This XML file contained a document.write("<script> .... </script>"); which was breaking the xml file.
 For more details go HERE. Anyway, the problem was fixed by writing the javascript in a seperate .js file and it was included in the HTML page.  Enjai,
Puneet.H PKCS7 in .Net and PKCS5Padding in Java with JCEMy Client was encrypting using JCE on a app server running Java 1.3. The padding he was using is PKCS5 padding while in .Net i was using PKCS7 padding mode to decrypt. Both of us were using AES/Rijndael algorithm for encryption and decryption purposes.
I was wondering if the two padding modes were compatible. Yes, they are compatible with each other to block sizes between 1 and 255 bytes inclusive.

Puneet.H SharePoint - Business Data Catalog walkthroughI was looking out for some BDC related stuff and for some walkthroughs and tutorials.
Here is the MS Virtual Lab link to the walkthrough which i found really helpful. You have to be a MSDN subscriber and a MSN passport account helps.
Also editing the application definition file by hand is a pain. Using BDC MetaMan is advised. You can find it here.

Puneet.H Using SPSecurity.RunWithElevatedPrivileges: Get a FileWell, i had a SharePoint site running Forms Authentication and i had to get a file from the document library for editing. So i decided to give Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges method a try. This takes a void function which will be run in elevated priveleges. So creating/deleting MySite for users while adding them from a legacy system can be done without the application running in System Account.
Heres the sample code:
SPFile rFile;
SPWeb web;
using (SPSite site = new SPSite(serverurl))
{
web = site.OpenWeb();
// get the file
SPSecurity.RunWithElevatedPrivileges(GetSPFile);
// read the file
StreamReader streamReader = new StreamReader(rFile.OpenBinaryStream());
filecontent = streamReader.ReadToEnd();
// do some file manipulation
/*
.......
*/
web.AllowUnsafeUpdates = false;
}
private void GetSPFile()
{
web.AllowUnsafeUpdates = true;
rFile = web.GetFile(strFileURL);
}

Puneet.H C# + Create a CSV Report
Heres the code to create a CSV Report in C#. Here reader is of type SqlDataReader. // Construct a comma-separated list all the column values in the current row
StringBuilder sb = new StringBuilder(); // to hold csv text file
// Create Header and sheet...
string quoter = @""""""; //
{
sb.Append( reader.GetName(j).ToString() ); // headings
sb.Append(","); // delimiter
}
sb.Append("\n");
// build the csv contents
string replVal = String.Empty;
while (reader.Read())
{
for(int k=0;k < reader.FieldCount;k++)
{
if(reader.GetValue(k).ToString()==null)
{
sb.Append("\"" + reader.GetValue(k).ToString() +" " + ",");
}
else
{
string temp = reader.GetValue(k).ToString();
replVal = temp.Replace("\"",quoter);
}
replVal+= " " +",";
sb.Append(replVal);
} //end if
sb.Append("\n"); // new row
} // end while
reader.Close();
reader = null;
SharePoint 2007 + Blocked File TypesIn order to add or remove a file type being added to your SharePoint portal you will have to add/remove the extension of the file from blocked file types. To find out the blocked file types you will have to goto Central Administration -> Operations -> Manage Blocked File Types. You will see a list of extensions. In order to remove a file type, delete the file type and click OK. In order to block a file type, just add it to the list in a new line and click OK. For more information go HERE. SharePoint + HTML EditorWell, if you wanted a HTML editor in your SharePoint application then read on...
SharePoint uses a HTML editor present in http://Server:portno/_layouts/htmledit.aspx for its own purposes.
I have put forth the JavaScript code required to popup the HTML editor. I also have to warn that for some reason you are presented with messy JavaScript errors when you try to highlight the text background or change the color of the text.
<script language="javascript">
function jsPopupEditor() { var rc = new Array(0,0); rc = window.showModalDialog('http://Server:portno/_layouts/htmledit.aspx?Target=hdnTxt',document.getElementById("hdnTxt"),'dialogHeight:450px;dialogWidth:450px;'); if (rc != null){ document.getElementById("hdnTxt").innerHTML= rc; document.getElementById("hdnTxt").value = rc;} } </script> Here hdnTxt is a hidden multiline textbox containing the HTML to be edited.
