I hate to say this, but you're going to have to resort to using P/Invoke here.

 how wonderfull. Why provide means to detect ReparsePoints but no means to do something like:
<br />
DirectoryInfo rootInfo = new DirectoryInfo("C:\myReparsePoint");<br />
foreach(DirectoryInfo subInfo in rootInfo.GetDirectories())<br />
{<br />
...<br />
}<br />
(the example above will end up with a security exception)
And even better, no means to actually make any sense to the actual target of a ParsePoint when you "find" one....
Ah, well. You dont happen to have a clean example of how to P/Invoke something to find the target of a ReparsePoint?

I have made some progress with this problem. I'm currently able to retrieve the reparse point target when using a combination of CreateFile and DeviceIoControl (P/Invoke). However the code only works on Windows 2000/2003/XP. When I run the same code under Windows Vista, I dont get a valid file handle when opening the reparse point with CreateFile. I'm suspecting that the security model in Vista is to blame (I'm tryng to find the target of "My Documents\My Videos", which I dont even have access to with my own user in my own documents folder).

Hi
Im having a .CSV file which is not having header,It has only the records to import to database.
I can able to read the csv file using ODBC, But the resultant Datatable takes the first record as the Header. Always its neglecting the first row.It starts reading from the second row.
How to solve this issue.
Help me out
Thanks in Advance

Hi there!
Try this:
Add the following criteria to the ODBC connection string, after the datasource.
If there are no headers (as it is with your case): "HDR=NO;"
Otherwise: "HDR=Yes;"
Hope this helps!

Hi Guys,
The random number in c# using System.Random.NextDouble() is not returning a good set of random numbers over 10000 iterations, there seems to be concentration for a consecutive iterations on set of values, my code looks like this
System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\test.txt");
for (int i=0;i<10000;i++)
{
RandomNumber = new Random();
string lines = "iterationCount"+ ":"+" "+i.ToString()+ " "+RandomNumber.NextDouble().ToString();
file.WriteLine(lines);
//}
}
file.Close();
is there a better way of generatin random numbers in c#?
Many Thanks
happy coding!

Put that line outside the loop.
When you create a new Random number generator it is seeded against the current time. If the loop is very short there is no time for the clock to update, so it gets reseeded against the same time as the last iteration, therefore producing the same number again.

I'm developing some desktop applications in Visual Studio 2005 and wonder if there are any tools to change colors(gradient) and shapes on controls in a easy way?
|
|
|
|
|
Yes. The user simply changes them in his "Display settings". In case you have never seen this you can find it in the "Display" Icon in "Control Panel"

If you want to work with .NET 3.0, then you can easily change gradients and drawing styles of standard windows controls using WPF.

Hello...
I make a new control and put it in a new form. How can I detect, if the control is loaded in Visual Studio Designer or directly in Runtime ?
Because if the control is loaded in designer, it shows some stranges behaviour. That's why, I want to cancel it, if the control is in designer.
Thx...

Hi there
Assuming you're talking about WinForms here: There is a DesignMode property, which can be evaluated. Do note, however, that you cannot use the property in the designer - this is why I usually use OnLoad. Here's a sample, which also plays nicely with controls you're going to extend:
///
/// Inits the base class and registers event listeners.
///
/// <param name="e" />
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
if (!DesignMode)
{
//your internal initialization logic
InitControlInternal();
//the template method below - for extending classes
InitControl();
initControlCompleted = true;
}
}
///
/// An empty template method which is being invoked after the
/// control has been loaded during <see cref="OnLoad">.
///
/// <remarks>The base class does not invoke this method if
/// the control is in design mode.
protected virtual void InitControl()
{
//this method is supposed to be overridden. Initialization of
//the base class itself happens in InitControlInternal
}
HTH,
Philipp

What if there is more than one instance of the form class?

What about your answer. For the most part it was a clear as mud.

Don't try passing values between forms. A neater architectural approach, is to abstract the data model from the actual visual representation of the value. One way to do this is to implement something called the Model View Controller[^] pattern.

have a public variable in mdi window,
once you open the child forms, in the form load assign the control to mdi public variables
instead of access the form2 text box , access the mdi variable.

I am using C#, GDI+.
I have drawn the line (using DrawLine()) from point(10,10) to point(20,20). The center point of the line is (15,15). Suppose i Rotate At(10,10) the line for 30 degrees.
How to calculate the center point after rotating?
|
|
|
|
|
For a line from (a_x,a_y) to (b_x,b_y) this is very simple.
The center is always ( (a_x+b_x)/2, (a_y+b_y)/2 )
So either you have the new endpoints and use this formula or
you apply your transformation to the old centerpoint (yes you can do this in .net)
