Rather than using Shell, you should create a Process object to run the command. The Process class allows you to wait for a return code that signals the execution has terminated.

Good afternoon
XmlTextReader behaves very strange: I have the following
encoding-definition in my (valid) XML-File:
encoding="ISO-8859-1"
If I open the File:
fileStream = new StreamReader (xmlFile);<br />
xmlReader = new XmlTextReader(fileStream);
an read some values, I can see that the Encoding is set
to "UTF-16" and I don't get all data: XmlTextReader
absorbs non UTF-16 characters.
If I explicit define the Stream-Encoding to:
fileStream = new StreamReader(xmlFile, <br />
Encoding.GetEncoding("ISO-8859-1"));
then XmlTextReader works perfect.
Is it wrong to except that XmlTextReader relates it's encoding
to the XML-Definition and not to the stream encoding?
Or: Do I really have to open the xml-file to check the
encoding-property and then to open the xml-file
again using the right stream - encoding?
Thanks a lot for any hint in advance,
kind regards,
thomas

Hi,
I have a form containing just a Microsoft WebBrowser Object. Im using it to view Excel files in my app (workaround for no OLE support). Only problem is, the controls take a long time to load, so I'm trying to get them to initialize in another thread when the app begins. There are two stages to the init of one such form: the constructor, where the activex control is inited, and the View() command, which causes the control to navigate to the specified file.
I've found that if I call View() straight after calling the constructor, the control freezes and Excel shows an "Out of memory" error box. However, if I move the View() call to when a user presses a button, for example, it works perfectly. It's somewhat strange, and i cant find any events that tell me when the control is finished initing. Can anyone help me please?
Thanks in advance

Hi,
I have created an dll Using .NET framework 2 (Beta 2) with CLR option off
(as my underlying implementation is C++).
1. Now when I am trying to deploy this on a machine which has just .NET framework 2 redistributable on it. I get error while registering this dll there.
I have kept Manifest generation and embed manifest options ON.
2. When I switch them (Manifest) OFF : It works fine, gets registered on that machine.
But on system with .NET framework 2 intalled and having XP, it fails to register...
Any suggestion why this must be happening..
thanks & regards

i have confusion that About CLR Memory Allocation / De-Allocation:
That if an managed class written in VC++.Net:
For e.g:
__gc class Client1
{
public:
Client1()
{
}
~Client1()
{
}
static double Square (double value )
{
value = value * value;
Console::WriteLine("Client1 Returning {0}",__box(value));
return value;
}
};
and i try to allocate it's instance as:
(1): Client1 * cl1 = new Client1();
and do not explictly delete it , then is it posssible that this instance will automatically be deleted by <CLR> of .Net?
-----------------------------------------------------------------------------
(2): An other confusion i have is that if i allocate an array of
<Client1> type objects such as:
Client1 * cl[] = new Client1 * [3];
will this instance will automatically be deleted by CLR or it also have to
explicitly destroyed using syntax < delete []cl; >
-----------------------------------------------------------------------------
(3): I create an delegate in VC++.Net
__delegate double Square(double);
use it in <_tmain> as:
Square * sq1 = new Square(0,&Client1::Square);
sq1->Invoke(3);
will the instance of this <sq1> delegate type object will be
deleted automatically by CLR or not?

in Managed code GC control all of these de-allocations automatically
,actually GC check them periodically and collect everyone of them that
ain't used.

Hi everybody I hope somebody can find a suggestion for this problem
I wrote store proc that work correctly in QueryAnalyzer but when I
call it from my project it make error "system error"
look at it:
CREATE PROCEDURE spSer_contact
@contactGroupID uniqueidentifier,
@countryID uniqueidentifier,
@contactName varchar(100),
@city varchar(50),
@phoneNumber varchar(100)
AS
declare @SqlString varchar(2000)
set @SqlString = 'SELECT contact.contactName,
contactgroup.contactGroupName,
country.countryName, contact.city,
contact.street, contact.zipCode,
contact.phoneNumber, contact.faxNumber,
contact.telex, contact.email,
contact.webSite, contact.comments,
contact.attachment,contact.contactID,
contact.contactGroupID, contact.countryID
FROM contact INNER JOIN contactgroup
ON contact.contactGroupID = contactgroup.contactGroupID
INNER JOIN country
ON contact.countryID = country.countryID
WHERE'
if (len(cast(@contactGroupID as varchar(38))) != 0)
set @SqlString=@SqlString+' contact.contactGroupID='''+cast (@contactGroupID as varchar(38))+''''
if (len(cast(@countryID as varchar(38))) != 0)
if (SubString(@SqlString, len(@SqlString) - 4, 5) = 'where')
set @SqlString = @SqlString + ' contact.countryID = '''+cast(@countryID as varchar(38))+''''
else
set @SqlString = @SqlString + ' and contact.countryID = '''+cast(@countryID as varchar(38))+''''
if (len(@contactName) != 0)
if (SubString(@SqlString, len(@SqlString) - 4, 5) = 'where')
set @SqlString=@SqlString+' dbo.contact.contactName='''+ @contactName+''''
else
set @SqlString=@SqlString+' and dbo.contact.countryID= '''+ @contactName+''''
if (len(@city) != 0)
if (SubString(@SqlString, len(@SqlString) - 4, 5) = 'where')
set @SqlString = @SqlString + ' dbo.contact.city = '''+@city+''''
else
set @SqlString = @SqlString + ' and dbo.contact.city = '''+@city+''''
if (len(@phoneNumber) != 0)
if (SubString(@SqlString, len(@SqlString) - 4, 5) = 'where')
set @SqlString=@SqlString+' dbo.contact.phoneNumber= '''+ @phoneNumber+''''
else
set @SqlString=@SqlString+' and dbo.contact.phoneNumber= '''+ @phoneNumber+''''
exec (@SqlString)
GO
====================
//sample code for retriving data by store proc
SqlConnection cn = new SqlConnection(connectionString);
SqlCommand cm = new SqlCommand("[spSer_contact]",cn);
cm.CommandType = CommandType.StoredProcedure;
SqlParameter pm = new SqlParameter("@contactGroupID",SqlDbType.UniqueIdentifier,16,"contactGroupID");
pm.Value = listBox1.SelectedValue;
cm.Parameters.Add(pm);
SqlDataAdapter da = new SqlDataAdapter(cm);
DataSet ds = new DataSet();
da.Fill(ds,"contact");//this have problem error message is (system error)
dataGrid1.DataSource = ds.Tables["contact"];
if somebody find a solution for this problem please send it
thanx

Is there any proper way of returning string from a function in a DLL ,
written in VC++.Net to the calling C# program.
plz i need this solution urgently....................

C# strings are unicode, so perhaps you need to return a BSTR ?

As You know in vc.net you can write managed and unmanaged code
Unmanage Code:
if you want to use unmanaged code use platform invoke
P/Invoke to call function you have in dll
Managed Code:
you can compile your code and reference this assembly from your project

Don't know if this is right to chip into your current topic or should I start a new one BUT....
There are functions in C++ like
"CVideoModes:CurrentVideoMode(CurrentMode)" that do not exist ( or I can't find them!)in C# in the .NET framework.
Where can I read more about imbedding C++ code in a C# program?

Ok guys, i not even know if it's a problem but i've seen many c# tutorials that explain assembly compilation by command line and i've seen they usually use "csc (my arguments...)".
That "csc" is a bit strange for me because they only use csc directly("c:\>csc myarguments..." for example) but i have to type all the path to the csc.exe file (C:\Windows\Microsoft.NET...csc.exe Myarguments...).
How can i create a link to csc?
Thanks in advance

Create a .txt file, open it and paste %comspec% /k "C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Tools\vsvars32.bat" (or something else, go to Start->All Programs->Microsoft Visual Studio .Net 200X->Visual Studio Tools->Right-Click Command Prompt->Properties->Target->Paste that line)
Save the text file, and rename it to .bat, Now you can doubleclick and you have a shortcut to all Visual Studio programs, you can just type csc and the command prompt knows what you mean.

Hi All,
I have a custom datagrid with two checkbox controls in it.
When checkboxA is checked then if checkboxB is checked, it is unchecked and vice versa. (not like a radio button since if checkboxA is unchecked then nothing happens to checkboxB).
But I would like to implement this in client side...any help would be GREATLY appreciated!
