I am writing a backup program and the user would like to enter the name or IP address of a machine and then my program would grab all the shares (I only care about the folders) from that machine and backup those folders. Does anyone know how to do this. I have tried using the ManagementClass but cannot figure it out yet.

hi friends and excuse for this long post,
i got some idea from greeeg about making a picture white and black. the method was:
public static bool GrayScale(Bitmap b)
{
BitmapData bmData = b.LockBits(new Rectangle(0, 0, b.Width, b.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb);
int stride = bmData.Stride;
System.IntPtr Scan0 = bmData.Scan0;
unsafe
{
byte * p = (byte *)(void *)Scan0;
int nOffset = stride - b.Width*3;
byte red, green, blue;
for(int y=0;y<b.height;++y)>
{
for(int x=0; x < b.Width; ++x )
{
blue = p[0];
green = p[1];
red = p[2];
p[0] = p[1] = p[2] = (byte)(.299 * red + .587 * green + .114 * blue);
p += 3;
}
p += nOffset;
}
}
b.UnlockBits(bmData);
return true;
}
</b.height;++y)>
it takes a picture as the argument and processes it to make it white and black.
then, again greeeg helped me and gave a method to make picture become white and black in a defined timings (like the smooth conversion of colored screen to grayscale when you click 'Turn Off' in strat menu in windows xp):
const float transitionTime = 5000f;
float normalizedTransitionTime = millsecondsSinceTransitionStart / transitionTime;
red = (byte)Lerp(normalizedTransitionTime , coloredPixelR, bwPixelR);
green = (byte)Lerp(normalizedTransitionTime , coloredPixelG, bwPixelG);
blue = (byte)Lerp(normalizedTransitionTime , coloredPixelB, bwPixelB);
and said that the Lerp method is actually works like this:
float Lerp(float amount, float value1, float value2)
{
return value1 + (value2 - value1) * amount;
}
for conversion of a picture from colored state to gray scale in a time like 500 milliseconds i merged the above ideas (of greeeg).
so i changed the first 'GrayScale(Bitmap b)' method to this:
public static bool GrayScale(Bitmap b)
{
BitmapData bmData = b.LockBits(new Rectangle(0, 0, b.Width, b.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb);
int stride = bmData.Stride;
IntPtr Scan0 = bmData.Scan0;
unsafe
{
byte * p = (byte *)(void *)Scan0;
int nOffset = stride - b.Width*3
byte red, green, blue;
for(int y=0;y<b.height;++y)>
{
for(int x=0; x < b.Width; ++x )
{
blue = p[0];
green = p[1];
red = p[2];
p[0] = (byte)Form1.Lerp(1f, (float)p[0], (float)(.114 * blue));
p[1] = (byte)Form1.Lerp(1f, (float)p[1], (float)(.587 * green));
p[2] = (byte)Form1.Lerp(1f, (float)p[2], (float)(.299 * red));
p += 3;
}
p += nOffset;
}
}
b.UnlockBits(bmData);
return true;
}
</b.height;++y)>
i have just changed the poinings of second 'for'
for example 'p[0]' is as blue in 'blue = (byte)Lerp(normalizedTransitionTime , coloredPixelB, bwPixelB)'
and the result was unsuccessful
have i done a correct work till now? (ofcourse not  )
i think the problem is in choosing the second and third arguments of 'Lerp (normalizedTransitionTime , coloredPixelR, bwPixelR)'.
finally, my questions are:
1- what should the arguments be then?
2- can i change Red, Green and Blue colors of picture (to make it gray scale) in an other way (without using the pointers in 'GrayScale(Bitmap b)')?

Yes, but it would be much slower. This is the fastest way to do it. Sounds like someone else has done all the work for you so far. I'm not sure what you're asking exactly, 'the result was unsuccessful' doesn't tell us much.

i don't know how to use these two methods to make a smooth conversion of colored picture to a gray scale one in a ditinct time.
yes, i myself never could guess to use such pointers to do my work. i'm learning from the friends.

Well, not sure why I would help you if I get a 1 vote for my trouble, but, the fact is, for bigger images, you probably can't. You'd need to create the individual frames first, THEN roll through them, for it to be smooth.

you mean to make the frames as an *.jpg in a folder and start to play them in my form like an animation. so the new and i think main question is "how is making a half grayed picture to produce the frames"?
i mean a picture which is not completely colord nor completely gray.

Actually, an easier way to do all this. Create your grey image. Then draw it on top of the color one over and over with varying transparency, which you get by setting the opacity of the ImageAttributes class.

I am trying to programmatically change the IIS settings for a folder. I have been following the following article, which shows how to use the DirectoryEntry class to manage active directory settings: http://www.codeproject.com/KB/system/everythingInAD.aspx#10
This code has been working to change the settings for the root directory of my folder, the IISROOT/MyAPP folder. My problem is that I need to change IIS settings for the IISROOT/MyAPP/Child folder, but have not been able to get a handle to the child folder using the DirectoryEntry. Is there a way that I can get a DirectoryEntry variable for this child folder, so that I can change the appropriate settings?
|
|
|
|
|
I figured it out. Before setting the path for the MyAPP directory, I created the child directory as an "IIsWebDirectory". When I properly set the path for the parent, the child directory was appropriately filled with files.

I want to genericize a class so that it can be used in any application. This class loads application settings. The problem is that in order to load the application's settings, I have to use the application's namespace (?) to do it, like so:
namespace MyApp
{
public class AppSettings
{
public AppSettings()
{
somevar = MyApp.Settings.Default...
}
}
}
How do I change it to something like this:
namespace MyApp
{
public class AppSettings
{
public AppSettings()
{
myapp = SomeMagicHappensHere();
somevar = myapp.Settings.Default.blah blah blah
}
}
}
When I hover over MyApp in the constructor show in the first example, it shows the type as "namespace", but I apparently can't cast to that type (or I'm doing it wrong).
Can anyone help?

John,
Right, MyApp is the namespace, just like System is the namespace for System.String. Namespaces aren't types by themselves, so you can't do things to them like you would to classes.
Would something like this work?
public AppSettings(ApplicationSettingsBase settings)
{
}ApplicationSettingsBase is the base class for all project settings. You would construct your AppSettings class like this:
AppSettings settings = new AppSettings(MyApp.Settings.Default); Is that what you're looking for?

I assume CVS is your source code evrsion manager, so the answer is really in the Tortoise Tip -

You know how the xml writer automatically makes the ampersand character (&) into it’s character entity reference ‘&’. Is there anyway of preventing it from doing this. I am working with an application that does not read the file the xml writer creates with an xml parser, therefore the character entity reference ‘&’ reference never gets parsed back to an ampersand. This is causing an error with the application because it does not understand the ‘&’.
|
|
|
|
|
IF you dont quote & it is not valid XML any more.
But if you really want it, just write out the file using the XmlWriter, and then just read over the created file/stream and replace & with &.

|
|
|

Fix the application that does the reading.

Hello gurus,
I have a request for you.
I have imported a flat file (delimited text file) into a DataTable from a DataSet. I wish to run an SQL statement such as "SELECT toto as X, count(titi) as Y from MY_TABLE GROUP BY X, ORDER BY X" where 'toto' and 'titi' are field from the MY_TABLE.
How is it possible to do that in C#?
I hope my question is clear. If not, let me know, I'll try to explain in better way.
Best regards.
Fred.

You can use LINQ for that if you have VS2008, else it's not really possible.

hi bouli
Firstly your Question is not Clear , you have imported a Flat File into a Datatable from a Dataset, its not making sense at all. Please Tell us Step by Step and show us your code, where you import and so we can understand what you mean and we will take it from there.
Hope it helps

Okay,
Sorry for my poor english.
I have sucessfully imported a CSV file into a DataSet.
I need to execute an SQL statement using COUNT, GROUP BY and ORDER BY. The request is done and works fine. I need to run it in C#.
While the data remain in a DataSet, I would like to know how I can execute the SQL statement on this DataSet?
Best regards.
Fred.
