Hi,
Are you talking about XML Documentation? Actually I am not getting your point / problem ?

Open the properties of your VS project, select the second tab called build or similar (its named Erstellen in my german VS), scroll down to the output section and specify a path for the XML documentation file.
The following article may be of interest for you as it present a nice way to turn the XML file into a pretty API documentation. Sandcastle Help File Builder[^]

Newbie question here...
How to use SecondaryBuffer.Read(...)
to get filled buffer value ?
I got random exception when call it.
Thx..

You need to provide more information before we can help you. What is SecondaryBuffer? What exception do you get when reading?
|
|
|
|
|
I used Managed DirectX, and use SecondaryBuffer in DirectSound namespace.
I think (maybe) it caused by start read position and length parameter that I pass in SecondaryBuffer.Read method.
Any resource on Web about this?

Hi Guys,
In C# Is there any way to find a date (paterns: 01/11/2005, 1/2/06, etc) in a string or text file?
eg:
string transcation = "Transaction initiated on 3/5/2005 and approved on 12/09/2006";
Now i need to extract the dates from this string, no prior knowledge of what the string contains & the date format could be different.
Thanks
Mohan

Check out the System.Text.RegularExpression.Regex class. You can use regular expressions to find date patterns. For more information, see this article[^].
|
|
|
|
|
As Judah said, you can use a regular expression.
You have to decide what date formats you will accept, as there is no way that you can extinguish any possible date format.
For example a string like "Our quest began in the third day in the fourth month in the year of the lord 1623." is clearly a reference to an exact date, but it's rather hard to write a program that will recognise it.

Hi,
I've written a few programs and have never come accross this before:
<br />
public Main()<br />
{<br />
InitializeComponent();<br />
bool startupCheckValue = true;<br />
startupCheckValue = checkCorrectDirectory();<br />
if (!startupCheckValue)<br />
{<br />
this.Close();<br />
Application.Exit();
}<br />
checkDBHasVersionControl();<br />
getDBVersionNumber();<br />
}<br />
When startupCheckValue returns false, the program executes this.Close as well as Application.Exit but it just keeps going!
I've stepped through it and can't see why the app doesn't exit 
Help please!

I recall there are issues with exiting the program inside the constructor of a form.
Perhaps you could set a flag in your constructor when you need to exit. Then override OnLoad, and if the flag is true, try exiting there.
|
|
|
|
|
Use an else statement so that checkDBHasVersionControl() and getDBVersionNumber() only execute on success and don't continue to execute any more code on the thread.
|
|
|
|

Thanks for the pointers  .
I solved the problem by completing the if .. else statement as follows:
bool startupCheckValue = true;<br />
startupCheckValue = checkCorrectDirectory();<br />
if (!startupCheckValue)<br />
{<br />
Application.Exit();<br />
}<br />
else<br />
{<br />
checkDBHasVersionControl();<br />
getDBVersionNumber();<br />
}
and moved it into the Form_OnLoad process.
Cheers ..

I was looking for an approach to repaint a rectangle included on top of a control in the paint event handler. The paint event handler normally paints the whole control. If there is a rectangle on top of the custom control in the paint event handler that changes based upon which background image is provided for the control, how could I repaint that rectangle?
With Amar's assistance I was able to create and retrieve an extended property for the customized user control. Thus, the background image can be changed. However, now I need the rectangle in the paint event handler to be forcibly repainted.
I tried the ctrl.Invalidate() and ctrl.Refresh() and ctrl.Update methods in the _ctrl_BackgroundImageChanged(object sender, EventArgs e) event handler, but these approaches did not work. Any suggestions on how to repaint the clientRectangle that was created in the _ctrl_Paint event handler from the _ctrl_BackgroundImageChanged event handler?
I even tried to do the following:
public static Rectangle clientRectangle
private static void _ctrl_BackgroundImageChanged(object sender, EventArgs e)
{
Control ctrl = ((Control)sender);
ctrl.Invalidate(clientRectangle, true);
ctrl.Update();
ctrl.Refresh();
}
How do I repaint the entire control and any rectangle objects attached to the control?

Oh, and by the way, "plz help" is a really useless subject. Try to write a more descriptive subject the next time.

Of course not, but it has nothing to do in a subject line. Almost every thread here is about someone who asks for help, so the information has no value what so ever to distinguish the thread from other threads.
suma12382 wrote: and i tried many subject b4 but no responsed
I don't think that has much to do with the subject line. It's more likely because you don't even bother to try to write proper english. Txtspk is rather frowned upon in serious message boards, and some people simply ignore messages that contains "words" like "u", "plzzzzzz", "b4", "thx".

I'm pulling a lot of hair here - not much left, so kindly help.
I am trying to read and modify the contents of two tags (LoadBehavior and CommandPreload) in the following XML:
----------------
<?xml version="1.0" encoding="utf-8" standalone="no"?>
<Extensibility xmlns="http://schemas.microsoft.com/AutomationExtensibility">
<Addin>
<FriendlyName>someaddin</FriendlyName>
[...]
<LoadBehavior>1</LoadBehavior>
<CommandPreload>1</CommandPreload>
[...]
</Addin>
</Extensibility>
----------------
My knowledge: I have a rough idea of what XML is, have no idea of the purpose of namespaces (other than making me hate XML more), and got the XML loaded into an System.XML.XmlDocument (yay!)
My problems:
============
(a) "navigation" in the presence of the namespace. Currently I do
---------------------
string nsname = "http://schemas.microsoft.com/AutomationExtensibility";
XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("xx", nsname);
node = xmlDoc.SelectSingleNode("/xx:Extensibility/xx:Addin/xx:LoadBehavior", nsmgr);
this works, but having to prefix "xx" to every element in the path seems counterintuitive, and make writing generig methods a pain. Any better way? (note that I have to live with the namespace)
(b) Replacing an element
----------------------
I want to modify these elements, but want to create them if they are not present.
Currently, I do:
XmlNode parent = xmlDoc.SelectSingleNode("/xx:Extensibility/xx:Addin", nsmgr);
if (parent != null)
{
node = xmlDoc.SelectSingleNode("/xx:Extensibility/xx:Addin/xx:CommandPreload", nsmgr);
if (node == null)
{
node = xmlDoc.CreateElement("CommandPreload", nsname);
parent.AppendChild(node);
}
node.InnerText = preload.Value ? "1" : "0";
}
That seems utterly verbose, as I have t mix in my own application logic, and my solution to getting the namespace right makes putting this into an isolated function utterly tricky.
