root has no child studentNode.
You must use the parent node from your foreach loop

I tried this way. Is this the way, you want me to do? I'm facing the same exception
foreach (XmlNode node in fieldNodes)
{
if (node.Attributes["name"].Value == cmbAssetClass.Text)
{
for (int i = 0; i < node.ChildNodes.Count; i++)
{
if (node.ChildNodes[i].Attributes["id"].Value.ToString().ToUpper() == drChangedNode["id"].ToString().ToUpper())
{
studentNode = node;
break;
}
}
}
if (studentNode != null)
break;
}

Didn't try it, should work

Hello,
I have developed an application in c#, i have also done reporting in it. My application contains folder Reports with .rpt files in it. Currently i m giving the report file path as the full system directory path, i want to give the path directly by using my application boundary,not the complete path. how can i fetch the .rpt file path from the Reports folder, Plz help...
|
|
|
|

try using Application.ExecutablePath and strip off the .exe file.
For example:
get the full name of the directory containing your .rpt file.
string strExeName = Application.ExecutablePath;
FileInfo fleExeFileInfo = new FileInfo(strExeName);
string strExeDirName = fleExeFileInfo.DirectoryName;
then get the parent directory of the .rpt by using...
string strParentDir = fleExeFileInfo.Directory.Parent.FullName;
hope this helps....

It worked, thanks alot

By any chance are you not aware of Application.StartupPath ?? Then yo don't have to do all these string manipulations..

hi
I want to make grouping in the data grid view. like
Table 1
pk col1 col2
1 ABC 51
2 DEF 74
-----------------------
Table 2
pk col1 col2 col2 col3 fk(pk_table_1)
1 abc 3 23 111 1
2 def 3 45 74 1
3 kki 8 23 871 2
4 qwe 2 15 5 2
5 eed 7 41 91 2
------------------------------------------
Now I want to show the data in the grid but in summarized form. like only the data that is in table 1 will be displayed first and at the left most a + sign will be displayed when we press that the data of table 2 will be displayed then.
Thanks

There's no question in this post, that makes it somewhat harder to formulate an answer.
AFAIK, the requested behaviour isn't standard available in the DataGridView. It might be best to look for a 3d-party grid that supports drill-down and grouping.

I have written the simple code as below:
Addede reference (C:\Program Files\Microsoft Visual Studio 9.0\Visual Studio Tools for Office\PIA\Office11\Microsoft.Office.Interop.Excel.dll)
private void button1_Click(object sender, EventArgs e)
{
Microsoft.Office.Interop.Excel.Application _objAppln;
Microsoft.Office.Interop.Excel.Workbook _objWorkBook=null ;
_objAppln = new Microsoft.Office.Interop.Excel.Application(); // To initialize excel file
if (_objAppln != null)
{
_objWorkBook = _objAppln.Workbooks.Add(Type.Missing); // To add workbook with sheets in excel file
//_objWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)_objWorkBook.ActiveSheet; // To get the current active sheet in excel file
}
string _fileName = "temp.xls";
_objWorkBook.SaveAs(_fileName,
Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookNormal, Type.Missing, Type.Missing, false, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
_objWorkBook.Close(true, _fileName, false);
_objAppln.Quit();
_objWorkBook = null;
_objAppln = null;
}
After the code is execuled, the instance of Excel (EXCEL.exe) is seen in taskbar. I have as many number of instances, as many times I click on the button.
The instance exists even when I stop the application.
What is wrong in the above code.

Hi
I had the same problem
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
after setting _objAppln=null; worked for me
greets
|
|
|
|

Explicitly calling GC.collect is not recommended. Is there any other good way to handle it?

Try releasing the Excel Application COM object by using the following code:
try
{
if (objAppln!= null)
System.Runtime.InteropServices.Marshal.ReleaseComObject(objAppln);
}
catch (Exception)
{
}
finally
{
objAppln = null;
}

I'm missing the code to close the workbook and exit the Excell application.
Meh, they're there, just overlooked them.
This kb-article[^] might help. The only other alternative[^] that I can offer;
Marshal.ReleaseComObject(workBook);

Hi,
To compare two datarows, I used Equals method as shown below. But it returns false, though the rows are equal.
dtGridOld.Rows[i].Equals(dtGridNew.Rows[i])
Please let me know the correct way. Thanks in advance
|
|

Because DataRow is a reference item, the Equals comparison checks to see if they are the same instance. Since they aren't, the comparison always returns false.
Use the DataComparer instead:
IEqualityComparer<DataRow> comparer = DataRowComparer.Default;
DataRow rowOne = (DataRow)table.Rows[0];
DataRow rowTwo = (DataRow)table.Rows[1];
bool bEqual = comparer.Equals(rowOne, rowTwo);
if (bEqual)
Console.WriteLine("The two rows are equal");
else
Console.WriteLine("The two rows are not equal");Note: This will not work pre .NET 3.5

Thank you..
while comparing, it is looking case sensitive data also. Though I set false to caseSensitive property of datatables.
dtGridNew.CaseSensitive = false;
dtGridOld.CaseSensitive = false;
Had I missed anything?

Case sensitivity of the data tables is irrelevant: it does not apply to row data extracted from the tables, just to the table as a whole - just as you would expect.
I know of no way to force case insensitivity on a DataRowComparer: you will probably have to write your own derived class! See MSDN and be prepared to work at it!
It may be that it would be easier to write a specific comparison routine for your two data rows, given that you know the data format you expect...

Hi,
I am trying to display 2 relational tables ('authors' and 'titleauthor' tables in pubs database of NorthWind) in a single DataGridView. I have selected SQLDataAdaptor from toolbox and made the join query on 2 tables. I also added a DataGridView on the form and binded it to Dataset. I have the following code in my form load:
dataSetNew1.Clear();
sqlDataAdapter1.Fill(dataSetNew1);
dataGridView1.DataSource = dataSetNew1;
dataGridView1.DataMember = "authors";
My DataSet is getting populated, but i am not able to display the data in the DataGridView. Please help me out as i am new to Visual C#. 
Regards,
Priya.

Try setting AutoGenerateColumns on your DataGridView to true.
