In future, try and be more considerate. Choose the most appropriate forum for your question and post there only.

If you put any efforts in over the weekend I would suggest limiting that to reading some design material, perhaps patterns or something. Nothing directly related to your project.

Hi I would do the following: let's say you have 2 classes the worker class Worker and the Main Form frmMain public class Worker { public event EventHandler MyInterThreadEvent; public Worker() { // do something here } protected virtual void onMyInterThreadEvent(EventArgs e) { if (MyInterThreadEvent != null) { MyInterThreadEvent(this, e); } } public void ThreadMethod() { do { // do something here onMyInterThreadEvent(EventArgs.Empty); }while(something); } } public class frmMain:Form { private Worker MyPersonalSlave; // .. All the Form - Stuff coming here... public frmMain() { InitializeComponent(); MyPersonalSlave = new Worker(); MyPersonalSlave.MyInterThreadEvent += new EventHandler(MyPersonalSlave_MyInterThreadEvent); // start a thread here that makes you worker work. } private void MyPersonalSlave_MyInterThreadEvent(object sender, EventArgs e) { if (!InvokeRequired) // are we in the correct Thread? { // do what ever you want to do when the event gets fired } else // use the invoke on the form to run this method in the correct Thread { Invoke(new EventHandler(MyPersonalSlave_MyInterThreadEvent),new object[]{sender,e}); } } } Greets m@u

First try to access that file by giving permision to everyone in permission propertirs of folder. then if you are able to access then try with specific permissions Thanks and Regards Sandeep If If you look at what you do not have in life, you don't have anything, If you look at what you have in life, you have everything...

If you wish to append a child node to the document root of an already created XML file then be sure to have using System.Xml; then the following will add a node: XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load("path to your xml file that already had a root document node"); XmlNode newXmlNode = xmlDoc.CreateElement("tagname"); newXmlNode.AppendChild(xmlDoc.CreateTextElement("The tag's text node Value")); xmlDoc.DocumentElement.AppendChild(newXmlNode); -Spacix All your skynet questions[^] belong to solved

Ok I answered my own question, but for those who would like to know the solution: I called the function by "parent.parent.resize('iFrameId')" The parent.parent called the function in my classic asp page that holds the iframe. I then added the call to the OnResize event of the html tag on my aspx page. Hope that helps Paul C

Thanks for your help, much appreciated. I have decided to implement a Dictionary in order to create groups in session. Regards Paul

Ok I stand corrected :) Thanks for all your help, not had chance to try the cross frame scripting as have been away for a few days. Regards Paul

Thanks for your reply. I think we are going to stick with our XML approach but we were wondering if an object based approach was feasible. With the XML approach we do the following: 1)Generate XML on the master database (contains updates/changes) 2)Then compare the XML with old XML generated on the last update. 3)Work through the XML and outputting where any changes are discovered. 4) The out put contains information on the row and particular field that is different 5)We can then call SQL to update the specific fields that have changed as well as insert/delete rows where appropriate. Is there any easy way to do that using objects. Or is it best to stick with the XML approach? Regards Paul

Hi Mark, many thanks for response in regards to my question. The way the system will work is that we send an update to the client, they are than able to upload this xml file using the application, the application then applies the updates contaied within the file. We really want to be able to move away from shipping files with multiple versions, as we want the updater to be completly version independent. The reason we have chosen XML initially is that we can compare old xml to new xml file to genreate the necessary insert, updates and deletes. Plus if there are new columns it just means tewaking the sql that outputs the xml. Where as to do it by an object model, any methods/fucntions have to be all updated to cope with new columns/tables and any calls to those methods/functions must be updated. This would be laborious, unless there was a method to do it dynamically. The reason we are looking at an object model is that all our programming in the system uses this and we would like to replicate that for ease of use, but I do understand that XML is the most appropriate method. Thanks again Paul

oceanexplorer, Sounds like you are trying to host a web page inside of an existing webpage. It does not take ASP.NET to do this... Just an IFRAME tag: MSDN: IFrame Object (Html Reference)

You can either use the ImageField or TemplateField with an Image control, in the ImageUrl you can specify the url of a web page or a custom handler which is resposible for producing the image. In this web page ( or custom handler), you can simply save the binary data of the image into the output stream of the Response object. You can see the sample code in the Personal starter kit[^]

Many thanks for your help, worked a treat! If I could ask one more favour, as I am struggling with this at the moment! I am now trying to register my DLL in the COM+ Catalog. To do this I am taking the manual approach and using the regsvcs.exe tool provided with the .net framwork. However when I regiser the dll it comes back that I have derived classes found in the assembly and won't register, saying that classes must be public, concrete and have a default constructor. Why is this happening? As far as I'm aware I haven't got any derived classes apart from the serviced component which is required. Below is my code for my class: using System; using System.Data; using System.Data.SqlClient; using System.EnterpriseServices; namespace StepByStep7_1 { public class NorthwindSC : ServicedComponent { private SqlConnection sqlcnn; private SqlDataAdapter sqlda; private DataSet ds; public NorthwindSC() { // Create a connection to the // Northwind SQL Server database sqlcnn = new SqlConnection("data source=(local);initial catalog=Northwind; User ID = SA;Password = *********"); } // This method executes a SELECT query and // returns the results in a DataSet object public DataSet ExecuteQuery(string strQuery) { // Create a SqlDataAdapter object to talk to the database sqlda = new SqlDataAdapter(strQuery, sqlcnn); // Create a DataSet object to hold the results ds = new DataSet(); // Fill the DataSet object sqlda.Fill(ds, "Results"); return ds; } // This method updates the database with the changes in a DataSet object public int UpdateData(DataSet ds) { // Update the database and return the result SqlCommandBuilder sqlcb = new SqlCommandBuilder(sqlda); return sqlda.Update(ds.Tables["Results"]); } } } Many thanks for your help Paul
