You need to provide more information than this. Are you getting any errors? If so, what are you seeing? Have you provided a fully qualified path to the executable if the executable is not in the PATH? Have you checked that you have sufficient privileges to run the process from the ASPNET worker process?

the exe is running in local client and downloading the file from webserver
when i double click it i getting what i need from the server...
but i use the code system.diaganostic.process.start("exe");
it is calling the exe suceesfully but download is not happened and no errors are shown.....

That is not the way to download a file from the server. If it was, then this would be a major security flaw and a gaping hole through which exploit attacks could occur. What you need to do is to write the file to the response stream and set the content type appropriately. Note that you cannot directly execute the program. The user has to do this.
To download the file:
private void WriteFile(string fileName)
{
try
{
Response.ContentType = "APPLICATION/OCTET-STREAM";
string header = string.Format("Attachment; Filename = \"{0}\",
Path.GetFilename(fileName));
Response.AppendHeader("Content-Disposition", header);
FileInfo download = new FileInfo(fileName);
Response.Flush();
Response.WriteFile(download.FullName);
}
catch (Exception ex)
{
//Report out any errors.
}
}

1. The executable will be run on the server. Never the client.
2. The exe will be running with the same permissions as the webserver (typically the ASPNET account) - Does this account have the rights to do this?

ASP code executes on the server not the client. After reading this thread I have no idea what you are doing and it is possible that you don't either.

Trying to run the following console program from a 'Sam's' Learn C# book and getting a bunch of

I can't see it. You are going to have to provide the line numbers that the compiler is giving.
|
|
|
|
|
Is there an easy way to do that? (It comes out as a big mess if I copy/paste.)
The first error is Line 1, Col 2 for some weird reason. I've actually gotten 18 errors.

Remove the line numbers with following colon at the beginning of each line.

Thanks Stefan!  (Just noticed all the examples on cd for Day 8 of Sam's C# in 21 Days have
the same problem.)
On another note, is there a quick and easy way to remove a column of characters, for
future reference? (And to fix the rest of the programs quickly.)

it might be worth trying sams website, there may be updated working versions of the code available for d/l

I copy and pasted the class you posted into Excel and did a text to columns with : separator. I then copy and pasted column B into notepad then from notepad to a New Console application in VS. It did error with "A namespace does not directly contain members such as fields or methods" on compilation.
I looked through the code and noticed Excel had inserted a '0' above the line "class CircleApp". I removed this and it works perfectly.

Not sure if fiddling about with text to columns would be quicker than
a manual delete - I'm thinking the most efficient way to fix this
and similar problems might be with an Excel VBA macro?

hi, i just want to ask if there is a way to asign a null value to a variable of type int.
for example i can write this:
<br />
String testingString = null;<br />
while writting this gives an error:
<br />
int testingInteger = null;<br />
The error is: Can not convert null to 'int' because it is a value type
i am using this to assign a null value in database.
meaning the textbox the i take from it the value of the integer is empty i want to insert a null value in the database not an empty cell.
thanks in advance,

If you are using .NET 2.0 you can use nullable types. You just add a question mark to the value type to make it nullable:
int? myVariable = null;

Just remember that when you are assigning null to a database you have to convert it to a System.DBNull.Value

Because................
String is a reference type and
int is value type........

You might want to use a panel instead.
|
|
|
|
|
Or you could override the OnPaint event of the group box and make your custom painting, but this is some kind of hard.
|
|
|
|
|
Not really. But it would be simpler to use a Panel and override the Onpaint to draw the label text.

Hello Everyone,
Recently i want to convert an existing VB application to Visual Studio.Net(2005) using c#, Hibernate and Interbase database.
Now i m facing problem with the Hibernate connection.
I put the following code for Hibernate connection:
<nhibernate>
<add key="hibernate.connection.driver_class"
value="NHibernate.Driver.InterBaseDriver"/>
<add key="hibernate.dialect"
value="NHibernate.Dialect.InterbaseDialect" />
<add key="hibernate.connection.provider"value="NHibernate.Connection.DriverConnectionProvider" />
<add key="hibernate.connection.connection_string" value="Database=C:\ProgramFiles\Database\CLASS.gdb;User=SYSDBA;password=abcd" />
</nhibernate>
But this code generate an error.
Can anyone help me solving this problem?
Thanks in advance.

Hello
I´m working on a project that implements a SQL server 2005 DB as the main DB. Users should be able to extract an given project from the main server DB and "copy" it to there own local machine and work on it there (offline). When they return to work, they should merge it with the main DB.
And I hoped it would be possible to show conflicts through vs.NET so that the user can solve them.
I´m wondering if anyone out there has ever implementet a solution with Merge replication from SQL Server 2005 in Vs.Net 2005.
And if this could be the solution to my problem?
Thanx 
Spaz
