Re: how to display windows form chart inside webpage?

11-Dec-06 0:50

Yes, you can very well host a windows form or windows control in a web page, for that you need to make your form as a activex control, actually u just need to use the tlbexp.exe and get the .tlb file, make sure u gice a guid attribute to your class, u have to register the tlb using regsvr32 and use it as how u ll embed a activex control in a web page , using java script.

Changing a Column value in a DataRow

What i need to do is get a row from a nodeTag and then insert that row into a new table while editing a column value.

The code below is what i do at the moment, but it never changes the value e.g.: copiedRow[classLabel] = newValue;

DataRow row = nodeTag.OriginalRowRef;<br />
                                    mainDataSet.Tables["Modified" + nodeTag.ClassName].ImportRow(row);<br />
<br />
                                    DataRow[] copiedRows = mainDataSet.Tables["Modified" + nodeTag.ClassName].Select("[" + classStruct.ClassKey[0] + "] = '" + nodeTag.NodeName + "'");<br />
                                    foreach (DataRow copiedRow in matchingRows)<br />
                                    {<br />
                                        if (modifiedField.Equals(FieldModified.Label))<br />
                                        {<br />
                                            copiedRow[classLabel] = newValue;<br />
                                        }<br />
                                        else if (modifiedField.Equals(FieldModified.Name))<br />
                                        {<br />
                                            copiedRow[classLabel] = newValue;<br />
                                        }<br />
<br />
                                        mainDataSet.Tables["Modified" + nodeTag.ClassName].Rows.Add(copiedRow);<br />
                                        mainDataSet.Tables["Modified" + nodeTag.ClassName].AcceptChanges();<br />
                                    }

I fixed the error, by mistake i wasnt going through the in-correct data collection. The deadly copy and paste from another section of my code was to blame! Smile | :)

Righthand mouse-click to a tree-view should act like a lefthand mouse-click

Schmullus10-Dec-06 22:42

10-Dec-06 22:42

Hi,

I have a treeview in my application and a
righthand click on a node should have the
same behavior as a lefthand mouseclick.

For the lefthand mouseclick I use the eventhandler

<br />
private void treeViewServer_AfterSelect(object sender, TreeViewEventArgs e)<br />
{<br />
     // my code...<br />
} <br />

The righthand click should call the same handler. But
the eventhandler "click" of the treeview

<br />
private void treeViewServer_Click(object sender, EventArgs e)<br />
{<br />
     // some code...           <br />
}<br />

provides not the TreeViewEventArgs of the "AfterSelect"

Some ideas?

Thanx in advance

Erik

offline web service programming?

George_George10-Dec-06 21:54

10-Dec-06 21:54

Hello everyone,

I am programming with Window Mobile and I heard that in the .Net SDK supports not only web service SDK at client side, but also offline web service module support? That is really cool!

Could anyone recommend some samples/tutorials on this topic?

thanks in advance,
George

This sounds like you are talking about Smart Clients. Try this article for a view:

http://www.codeproject.com/smartclient/SmartClientSOA.asp[^]

the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer

Deja View - the feeling that you've seen this post before.

George_George11-Dec-06 2:54

11-Dec-06 2:54

Thanks Pete! The smart client is only for desktop application, other than for Windows Mobile application, right?

What I need is the ability to provide offline Web Services function for Windows Mobile application. Any comments?

regards,
George

Pete O'Hanlon11-Dec-06 3:26

11-Dec-06 3:26

George - the whole concept works for both Desktop and Mobile applications (in fact, I would say that it is better for mobile than desktop apps). Have you looked at the Smart Client Application Blocks or the Smart Device Framework?

Thanks for reply Pete! I have read through the document and related samples, and they are very informative. But, ... Smile | :)

, I have not found any information about offline Web Services support ...

Maybe I am wrong or careless. Could you kindly point it from the URL/document you mentioned please?

George

Which is the best book for learning C# ?

12-Dec-06 20:17

Hi Pete, in this Web cast, I only find some high level descriptions. Are there any materials about,

1. how to setup environment (both client/server side);
2. a simple sample with source codes?

In MSDN, I can not find.

regards,
George

just make sure when buying one to take a good look into the index to make sure it covers almost everything "sockets are missing most of the time!"

All generalizations are wrong, including this one!

If you are intermediate programmer with good background, usually by now you should be looking for best practices, not just knowledge. You may find some advanced books on topic -usually the is no book on advanced C# as a whole with very few exceptions-. For example you might look for books on Database programming, advanced remoting, network programming with C#, etc.. You can browser sites like Amazon[^] for that.

Yet in sites like CodeProjects you would find articles written by people who faced certain problems and solved them. These articles usually provide very practical solutions to problems and are one of the best way to increase your knowledge in programming.

Also forums and discussion borads -again like those in CP- ,offer you a much wider range of problems -and programming by some definitions is no more than problem solving-. There you'd find wide variation of problems that people faced, and this encourages you to search for an answer to help, and in the same time to learn. Even if you didn't get an answer, usually there are more experienced programmers who would provide a best answer for most of the question -most of the time a question would have more than one good answer-. You can learn and increase your knowledge by just browsing problems and their solution.
