manually when i set in DataGridView DataMember property at design time it is working fine, but programatically it is not. Why is that?
|
|
|
|

sorry maybe i was not clear my self try this:
after you fill the dataset with database you can get each row with:
<code>
foreach(DataRow dr in DS.Tables[0].Rows)
{
DGV.Rows.Add(dr[0],dr[1],dr[2],dr[3]...);
}
</code>
but first you should add COLs

I have an webbrowser control on my form. I am able display html files in that control. But my page contains some images if i give absolute path to it then images are displayed. But if i give relative path then images are not shown in the pages.
<br>I have HtmlPages folder located at bin folder.
<br>And i am assigning
FileStream source = new FileStream(@"..\HtmlPages\supportHtml.html", FileMode.Open, FileAccess.Read);
webBrowser.DocumentStream = source;
If i assign D:\myapp\bin\HtmlPages\file.png then there is no problem.
My images are stored in same folder. If i open html files with webbrowser then images are displayed.
What is the correct path to set ??

You're expecting that the application would load it's images from the same directory where your HTML-files are, as that's the way that it would work in a webserver.
I think that the application is looking in it's own "current directory", which is probably where the executable itself is located. My guess is that it will find the images if you put them there.

Hi,
by using webBrowser.DocumentStream = source; you are passing data to the WebBrowser without telling it where the data came from, so it cannot possibly use that location as its file base. Why don't you try webBrowser.Navigate(@"..\HtmlPages\supportHtml.html");

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;
}

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?
