Get any specific value from this xml [modified] - C# Discussion Boards

Hello,

I'm programming a little music helper and use the System.Drawing class, to draw the staves and notes on a PictureBox. I want to save that as Image, but all my attempts failed. Of course I used Google to find the answer and I found a advice. It says that I have to draw my things on a Bitmap first and save that. But How do I draw something on a Bitmap with Graphics?

I'm looking forward to your answers.

Best regards

edit: Sorry for my English. It isn't my mother-tongue.

Drawing anything in a Bitmap using a Graphics object is very easy. You will need to first create one bitmap object and use it for initializing graphics object.

Once you get one graphics object created using FromImage method, you may draw anything in this graphics object and it will be drawn on bitmap also.

At last you may save the bitmap using Save method of bitmap object.

Such as-

----------Start Code----------------

Bitmap a = new Bitmap(400, 300);

Graphics g = Graphics.FromImage(a);

g.DrawLine(Pens.AliceBlue, 0, 0, 100, 100);

a.Save(“C:\MyFile.jpg”);

--------------End Code--------------

I hope this helps Smile | :)

Hi which is the default script used in dot net?

If you mean to ask which is the default development language in .NET, then there isn't one. Out of the box, you can develop in C# or VB.NET (the compilers are included with the .NET runtime) and you can download/choose other languages as you see fit.

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

What do you mean? Please make it clear.
Do you mean scripting language by any chance?

EDIT: the XML isn't showing (download here: http://rapidshare.com/files/59995138/test.xml.html)

I have this XML.
I use the code below to open the XML and treat it as a DataSet and view it in a datagrid.

<code> try
{
dataset = ReadXML(szPassword);
dataGrid1.DataSource = dataset;
dataGrid1.DataMember = "principal";
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}</code>

put this in a different class, if you wish.

<code> public DataSet ReadXML(string szMyXMLfile)
{
DataSet ds = new DataSet();
try
{
ds.ReadXml(szMyXMLfile);
return ds;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}</code>

I want to treat The DataSet, NOT the XML, (change values, modify fields) through code.
How Can I get these fields from the dataset's ADM name into an ArrayList? (look at picture) http://bayimg.com/eaHdKAaBg
<code>store.all.admin
launch.more
launch.all
user-management
Direction</code>

Thanks for your replies.

EDiT: here's my current search routine
<code>
foreach(DataRow dr in dataset.Tables["principal"].Rows)
{
if (dr["name"].ToString()=="ADM") // "ADM" (for example)
{
foreach(DataRow dr2 in dataset.Tables["grant"].Rows)
{
textBox1.Text += dr2["name"].ToString() + Environment.NewLine;
aPermissoes.Add(dr2["name"].ToString());
}
if (textBox1.Text.Length>=2) textBox1.Text = textBox1.Text.Remove(textBox1.Text.Length-2,2);
}
}
</code>

Found a solution

<br />
	int nPrincipal_Id = 0;<br />
	foreach (DataRow myRow in dataset.Tables["principal"].Rows)<br />
	{<br />
		if (myRow["name"].ToString()==textBox2.Text)<br />
		{<br />
			nPrincipal_Id = Convert.ToInt32(myRow["principal_Id"].ToString());<br />
		}<br />
	}<br />
<br />
	foreach (DataRow myRow in dataset.Tables["grant"].Rows)<br />
	{<br />
				if (myRow["principal_Id"].ToString() == nPrincipal_Id.ToString())<br />
					textBox1.Text += myRow["name"].ToString() + Environment.NewLine;<br />
	}

Hi
Is there any way to get the user name that who has changed the file/folder. As for E.g , i have a shared folder , and one FSW is used to monitor the Folder , i am getting all changes, rename, delete or create result, but how i will get the user name of the same that who has create that file or delete that file.

using WMI , i can get the information that who are currently logged on in my system.....

But i am unable to get who has changed Confused | :confused:

Please Help !!!! Smile | :)

Thanks in Advance

Abhijit

You can't. NTFS doesn't track who makes changes to what files or deletes a file.

The only way to get the information on a Created file is to get the owner of the file from the files Security Descriptor.

Hi
I created windows application with c# and setup project that will install application.

For uninstallation i am using batch file which contains following code

MsiExec.exe /x [productcode]

while uninstallation it shows command window and it's looks bad.

I have already add shortcut to that batch file and it is uninstalling application from computer but shows command window behind uninstallation.

How can i hide command window or Suggest any other way to uninstall application

Thanks

thanks a lot
it works.
but still command window will blink for a second

Can i complete remove that window?

Rather than a batch file, write a simple C# console application and use:

C#

[System.Runtime.InteropServices.DllImport ( "kernel32" , SetLastError=true , EntryPoint="FreeConsole" )]
private static extern bool
API_FreeConsole
(
) ;
 
public static bool
FreeConsole
(
)
{
    return ( API_FreeConsole() ) ;
}

Use a System.Diagnostics.Process to execute the uninstall.

Using a System.Diagnostics.ProcessStartInfo you can set WindowStyle to System.Diagnostics.ProcessWindowStyle.Hidden and CreateNoWindow to false.

I tried to uninstall this way but still same problem

And you called FreeConsole?

Sorry but i couldn't get idea

Can you provide me whole code?

Is this comment right if yes plz explain it

Thnx

Answer was right here[^] on Code Project.

A simple search[^] would have yielded this.
