The simple answer is 'You can not'. The only FileOpen dialog you get is 'Browse' using , which creates a textbox and a button. Anything else might need ActiveX.

I see,it is XslCompiledTransform, in vs2003 we use XslTransform instead of it. In the FAQ of that article there is some detailed info about it(its name is "Net 1.1 version").;P

Thanks Steven.
I got the program working but i wasn't used to the XSL. After go'g thru the necessary docs i became somewhat familiar with that too.
Still the data from the dataset is not getting populated in the Excel sheet. As I went thru the XSl doc i came to know that
"<xsl:for-each select="NewDataSet/Table">"
The select keyword will select data from each inner node as per the depth specified. But here instead of XML file we are using dataset.
"<xsl:value-of select="ProductID"/>"
The select in here ---say "ProductID" IS it the field names that should be given as per our select commnd.
Is my problem something to do with the above.
Can u Plz suggest a possible solution for the same.
Thanks & Regards,
Jeeva

dataset is ok, i am just using dataset, u could use:
strExcelFile= objExport.TransformDataTableToExcel(ds.datatable(i),True)
objExport.SendExcelToClient(strExcelFile)
Also u have to have some polishment of ExcelExport.vb so as to run it in vs2003.
If u have any more question, u could sent email to me.
wish u could succeed!;P
Regards,
Steven

hi!

You can get that like this:
dataset.Tables[0].Rows[0][0].ToString();
This will give you the value of the first column of the first row of the dateset.

u can use
dataset.table["table name"].Rows[row number]["column name"];

private string GetWebContent()
{
string fullpath = @"http://www.google.com";
HttpWebRequest webreq = (HttpWebRequest)System.Net.WebRequest.Create(fullpath);
HttpWebResponse webresp = (HttpWebResponse)webreq.GetResponse();
StreamReader strm = new StreamReader(webresp.GetResponseStream(), Encoding.ASCII);
String text = strm.ReadToEnd();
strm.Close();
return text;
}
This is my code. it works well on my own computer, but when i put in my office computer, there is a WebException:
"The underlying connection was closed: Unable to connect to the remote server."
why? is it because the setting of firewall in the office server or something.
Thanks very much

It uses system IE settings. Are you able to use google.com in your office computer.
And IE profiles might interfere too.

Thanks.
i can use www.google.com in my office computer through IE.
and i do not understand "And IE profiles might interfere too"
could you explain it for me, and how to fix it then?

while converting a vb.net application to c#, one pagechangedeventhandler event in vb.net application gives error in C# . Also overridden finally method also gives error in C# and suggest to provide destructor. But also not allow to declare destructor in an abstract class.
I have converted vb code to C# . but not able to run the application due to above errors.
plz help

One thing you can try is to take the compiled assemblies of your application writtne in VB and then use .NET Reflector[^] to have it decompile and export the IL code in C#. Then you can compare what the decompiler did in the same section of code where yours is failing.

Can you post the original VB code that you feel isn't being converted correctly? I'll convert it for you.

Hello
how can i check that if my string is an integer or not ? if yes then return true else false;
plz help
regards,
max
|

u can convert ur string into array of char and then can check it through
method Char.IsNumber()
rahul
|
|
|
|
|
int result;<br />
bool isInt = int.TryParse("123", out result);
|
|
|
|
|
use Try and catch block with
int.parse
or
convet.int32() method.
if any error occur then false
else true.

Another good way:
If Not IsNumeric(strString) Then
bool = False
Else
bool = True
End If
