Hi.
How can I read command line parameters used to call a Windows Form Application?
I use VS2005 to create a new Windows application. The autogenerated Program.cs fle looks like this:
....<br />
static class Program<br />
{ <br />
[STAThread]<br />
static void Main()<br />
{<br />
Application.EnableVisualStyles();<br />
Application.SetCompatibleTextRenderingDefault(false);<br />
Application.Run(new MainFrm());<br />
}<br />
}<br />
....
Shouldn't the Main method header include a parameter for arguments?
Can I add it by hand? Are there any other options?
Thanks.

feel free to add the arguments to Main function. This wil stil work with windows forms
eg. static void Main(string[] args)
|
|
|
|
|
You don't need to do that, you can just call:
string[] args = Environment.GetCommandLineArgs();
FYI, args[0] is the app file name.

I created a Report using CR in .NET. The report has a couple of decimal fields .I want the output to look like : $55,345.06. I formatted the the fields by right clicking it, selecting the Number Tab and selecting the "Custom Style" option. The sample output showed $55,555.56. But when I ran the report I am getting values like 3456.6700. I am not getting the Dollar prefix and the output is not rounded to 2 decimal places.
Am I missing something? Please let me know

This is the tipical behavior in a situation like this:
- at design time, you have a number field, and you assign a number format to it.
- at run time, you have not a number value (e.g: it is a string value)
in such a case, format won't apply due to a internal exception handling, I suppose, you have not any signal.
Hope this help

Thanks for the reply.
Not sure if I got it . I am new to Crystal Reports.
How do I take care of the exception handling and fix the problem

Hello guys , i am trying to write smtp server .
there is two problems .
first when i run my server on port 25 it doesn't make clients connect on my pc knowing that this port is free to use on my computer host because i didn't install smtp server that comes in package with IIS6. i didn't install the smtp server that comes with the web server in order to be able to use port 25 but in vain i can't connect clients to send mails in my server on port 25 .
whereas i changed the port number just for testing to 23 and i successfully connect to it using telnet.
second problem:
--------------

Does the bind() succeed on 25?

The SMTP protocol is public. You can find documentation for it all over the internet. http://www.google.com/search?hl=en&q=SMTP+RFC&btnG=Search[^]

If that code is exactly identical to what you are running there is no way that you would get that exception.
Im guessing there is some form of reflection and/or remoting going on somewhere!

hi,
In my form i have a buttons, textBoxes, comboBoxes, labels,....
When i click on of the buttons a listbox that was set invisible is set visible.
It shows some names. The list box is located directly at the right-bottom corner or that button.
What i want is to make the listbox invisible whenever the user clicks the mouse at any location outside the listbox
I tried using the FocusLost event of the listBox, but that didn't work perfectly.
The problem it has is that whenever i click a label or a panel or something that doesn't receive focus, ofcourse the function is not executed.
With the FocusLost i tried to implement the MouseDown event of the form. That also didn't work.
Is there any way to do that without implementing a mouse click event on every label and every panel in the form.
thanks in advance

private void button1_Click(object sender, EventArgs e)
{
listBox1.Visible = true;
listBox1.Focus();
}
private void listBox1_Leave(object sender, EventArgs e)
{
listBox1.Visible = false;
}
private void WindowsApplication1_Click(object sender, EventArgs e)
{
listBox1.Visible = false;
}

hi, thanks for you reply but i have some comments
first what is this:
bobsugar222 wrote: private void WindowsApplication1_Click(object sender, EventArgs e)
there is no events for the windows application.
and if you mean by it form1 than i tried it and it didn't work
please clarify.
thanks again

Sorry, I that was from an earlier test of mine... I didn't think you were able to have the same class name as the parent namespace, so I renamed Form1 to WindowsApplication1... So it was the Form.Click event, yes.
There is no reason for it not to work. If you click the form, the listBox is made invisible. I think the reason your original method didn't work was because you never explicitly set the focus to the ListBox like I did in my Button.Click event handler.

Assuming the regular events dont offer a solution, here are two more ideas:
- you could use MouseMove and try and detect a mouse move going to leave the listbox.
this probably would involve two borders (two to detect the direction of motion, you
must allow the mouse to enter the listbox !). You may have to allow for some mouse jitter.
And be careful with the scroll bars.
- you could use a timer that periodically checks the mouse is still inside the lisbox
(with Control.MousePosition).

Hi qS,
I tried this out for ya, and could easily reproduce the problem you described. Buttons seem ok (they take care of invoking the Leave event on the ListBox), and handling the MouseDown event on the form takes care of hiding it in that instance. Panels cause a problem as they themselves capture the MouseDown event and therefore its not raised on the Form.
As an aside; I was sure there was a way to override this behaviour to tell specific controls to "pass all mouse and key events up the control heirachy. Each level should then be able to do the same thing - handle or pass the event. I cannot find this although im 90% sure it exists.
There is, like always, a sufficient workaround which is to intercept a control being added to the form and handle its MouseDown event also. You can re-use the same event handler as you used for your Form as they have the same signature (and you want the same behaviour - hide the listbox).
I added 1 button and 1 listbox to a form. I thn added the following event handlers:
private void button1_Click(object sender, System.EventArgs e)
{
this.listBox1.Visible = true;
}
private void listBox1_Leave(object sender, System.EventArgs e)
{
this.listBox1.Visible = false;
}
private void Control_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
if(sender != this.listBox1)
this.listBox1.Visible=false;
}
The last method there has a check that the mouse down event isnt actually on the listbox were using, as you need the mouse down event to set your selection. Then just override OnControlAdded:
protected override void OnControlAdded(ControlEventArgs e)
{
e.Control.MouseDown += new MouseEventHandler(Control_MouseDown);
base.OnControlAdded (e);
}
Nice!

Thank you for taking all the time to test my problem and figure out a solution.
Actually i did before the same solution you provided. it is working now.

Hi,
Hope every one is doing fine... well I've a little problem at hand regarding the above stated function... when this function is run in the environment of winXp or lower it works fine... but on Vista it gives different results and hence the comparisons fail very often... is there any other function that could convert BYTES in to STRING in the same way on every Windows Platform i.e. compatible for Vista as well...
Thanks in advance,
Regards.

Can someone please tell me what is wrong with this code in C#
have 2 web pages: page A and PageB
in page_load event for pageA I want the page to assign a value into a session variable and redirects to pageB, like this:
PageA
Session["Refid"]=1;
Respone.Redirect("pageb?refid="+ Session["Refid"]);
.
When I step run my codebehind by pressing F10, I notice it goes to the catch Exception part of my try...catch event and still redirects to pageB which shoudn't be. I believe once an error is raised it should print the error message instead of redirecting to pageB.
can someone help me out.
Thanks
