Please don't double post. You can delete the old one.
You need a third party library to do this, I think there are some examples on this site, just try searching.

Use the KeyDown event instead of the KeyPress and write in it:
if(e.KeyCode == Keys.Enter)
|
|
|
|
|
You mean not even a MessageBox appears?
In this case the event is the event properly set to this function?
There is a project ControlInspector[^]
that i found very usefull. It might help you in this situations.

Did you start any threads in your application that may still be running?

All threads you create are non-background by default, set their IsBackground=true
if you want these threads not to prevent application exit. Otherwise your app
will wait for all of them to finish.

Hi, this is follow up to my question earlier.
I've managed to select <entry> nodes with title"summary" using Xpath and would like to retrieve the attribute of <link href="XXX_SUMMARY.xml" />. The format of the XML is actually an atom feed format. Any advice pls. I'm at my wits end. Thanks.
<entry>
<title>Summary</title>
<link href="XXX_SUMMARY.xml" />
<category term="Route" scheme="137" />
<category term="TimeStamp" scheme="20070201101319852" />
<author>
<name>XXX</name>
</author>
<id>XXX_SUMMARY.xml</id>
<published>2007-02-01T02:13:19Z</published>
<summary type="text">EVENT_SUMMARY</summary>
</entry>
<entry>
<title>Report</title>
<link href="XXX_REPORT.xml" />
<category term="Route" scheme="9" />
<category term="TimeStamp" scheme="20070201100628191" />

if your xpath selects the title node and you want the next node then you can try something like this: node.nextsibling.innertext.....
otherwise, you can select the entry node and give node.childnodes[2].innertext....
Hope this helps!!!

thanks but it doesn't work. nextsibling will give the next node but I need to retrieve <link href> immediately after the title node.
I think using node.childnode[1] should select the correct <link href> and way for me to confirm this and retrieve the attribute? Thanks.

Calling SelectSingleNode("/link/@href") on the XmlNode instance that represents an entry node should return an XmlNode object representing the href attribute on the link element. On this object simply retrieve value of the Value property.

thanks...it works albeit with some minor adjustments. I selected using SelectNodes and using foreach to loop through the nodelist and not forgetting adding in the namespace part. I know you are just providing some directions instead of spoon feeding me. Thank you very much. You and all the kind hearted souls have been a great help.
thanks and best rgds.

Hi! Is is possible to come up with a C# application that uses databases but doesnt really need to install Mysql or Oracle? I am using a windows platform and I need to come up with an application that if installed in another computer, wouldn't need to install a database also.
Thanks very much!
|

|

As far as 2-tier achitecture is concern, the answer is yes. You don't need to install your application together with the database. You can create an application in any language that can connect to a remote database server.
