In case of Customer,
I should be having

hi
I want hiden the window of my project in the ConsoleApplication
but I don't know how I can doning it
please help me if you know about it

You must tell the system to start the application without a window. The following code will do it:
<br />
ProcessStartInfo psinfo = new ProcessStartInfo("MyConsoleApp.exe");<br />
psinfo.UseShellExecute = false;<br />
psinfo.CreateNoWindow = true;<br />
Process proc = Process.Start(psinfo);<br />
proc.WaitForExit();<br />
I don't think there is an easy way to hide the console window from the console application itself.

In addition to Christian's suggestion, I think you could instead create a Windows Forms application and simply not create or display the main form.

That would be certainly a bit less coding.

Hi
I want to send different files to different clients but at same time from server.
I've successfully sent a file to a single client and then to multiclients but at different times using threads.
As when server is sending a file to one client and during that transmission if another clients requests for a file then 1st transmission stops and 2nd one also gets prob.
so plz try to tell ASAP the appropriate solution for this.
Regards.

How are you "sending" files?
How does a client "request" transmission of a file?
A WCF service is one way to easily solve this problem.

If I put the values 5 and 2 in the TextBoxes txtValor1 and txtValor2,
in the TextBox txtResultado appear 2 and not 2.5 .
Why?
My code is:
<br />
long valor1,valor2;<br />
double resultado;<br />
<br />
valor1 = int.Parse(txtValor1.Text);<br />
valor2 = int.Parse(txtValor2.Text);<br />
<br />
if (opcDivide.Checked)<br />
{<br />
resultado=valor1/valor2;<br />
txtResultado.Text=Convert.ToString(resultado);<br />
}<br />
<br />
Thanks.

when you divide this two values try to cast and initialize to result
spaps
|
|
|
|
|
THe Result has to be cast into string...
TxtResult.Text= result.ToString();

Why?
Because the result of an integer division is an int. Thus the correct answer for 5/2 is 2.
If you want an answer of 2.5 you must use doubles.

|
|
<br />
<br />
double valor1,valor2;<br />
double resultado;<br />
<br />
valor1 = (double) txtValor1.Text;<br />
valor2 = (double) txtValor2.Text;<br />
<br />
if (opcDivide.Checked)<br />
{<br />
resultado=valor1/valor2;<br />
txtResultado.Text=Convert.ToString(resultado);<br />
}<br />
<br />
<br />
You code will fall over as soon as some bright spark enters a non number into your texbox, put a validator on it.

Though this isn't particularly robust code. Better would be to use something like:
double valor1, valor2;<br />
double resultado;<br />
<br />
if (!double.TryParse(txtValor1.Text, valor1))<br />
{<br />
valor1 = 0;<br />
}<br />
if (!double.TryParse(txtValor2.Text, valor2))<br />
{<br />
valor2 = 0;<br />
}<br />
<br />
if (opcDivide.Checked)<br />
{<br />
try<br />
{<br />
resultado = valor1/valor2;<br />
txtResultado.Text = resultado.ToString();<br />
}<br />
catch (DivideByZeroException e)<br />
{<br />
txtResultado.Text = "Error";<br />
}<br />
}

Hi,
two comments:
1.
moon_stick wrote: if (!double.TryParse(txtValor1.Text, valor1))
{
valor1 = 0;
}
can be simplified to double.TryParse(txtValor1.Text, valor1)
which does exactly the same, given the following from MSDN:
"When this method returns, contains the double-precision floating-point number equivalent to
the s parameter, if the conversion succeeded, or zero if the conversion failed. The conversion
fails if the s parameter is a null reference (Nothing in Visual Basic), is not a number in a
valid format, or represents a number less than MinValue or greater than MaxValue. This
parameter is passed uninitialized."
2.
It would be better to produce some error indication when TryParse fails.
With your code:
- a mistake in valor1 results in zero, which may be confusing
- a mistake in valor2 results in a divide by zero with a misleading error text

Hi Luc,
Of course you're right - I just couldn't be bothered checking the MSDN documentation to see what was returned if the cast failed sp decided to try and cover my bases.
I was treating the code as if it were working on a simple calculator and limited the range of error messages. In any case, I said it was better, not perfect!!

Can I work with linq using visual 2005 ?
Is there any kind of extension ?
Does it also mean that I can use xlinq (linq to xml) ?
|
|
|
|

It may be possible, if you have the .NET Framework 3.5, to use the Linq namespace in Visual Studio 2005, but you will not be able to use the LINQ syntax as they are a part of the C# 3.0 compiler. But since this syntax is just sugar that compiles down to using the appropriate classes then you can probably still use it, it will just not look as pretty.
|
|
|
|
|
Linq has been introduced as part of .NET 3.5, which doesn't run in VS2005. I'm afraid you need one of the VS2008 editions. Once you get it, you can use DLinq and XLinq to your hearts content.
|
|
|
|
|
You can use LINQ in almost any data source, its the higher level code that uses it not the backend database.
