hi, I have a login window that opens up before any other window of the application. the problem is that I m not able to close the login window upon authentication and then load the parent window of the system.
I use the following code to hide the login window:
this.FindForm().Visible=false;
but hiding the window is a very bad approach as though the form is not visible but it still is consuming memory.
the following code to close the window closes all the windows of the application, including the MDI parent form
this.FindForm().Close();
Please help

Use MDI container , open the login as the child of tht MDI, on successful login close the form as its a child it wont close the parent, open a new form which you want to show !
does tht help ?

Hi,
There is simple approach to this problem create MDI form
and on MDI Form_load event
formLogin.Showdialog() --for .Net--
OR
formLogin.show(vbmodal) --for VB classic--
[ remember formLogin is not a child Form ]
and At Last on Successful Login Close formLogin.Close
Thanks & Wishes

Hi,
I' ve a custom drawn panel similar to groupbox(with nice round borders and header text) . I would like to change it's dock bounds (offset it a little bit), so that when a control is docked inside my custom control, it won't overlay my custom drawn border and header text. I know there is a hidden property which handles dock bounds (can't remember it's name) or maybe changing the client area would help ? 
thanx

Hi,
I have a modal dialog that I don't want the user to close via the close button, how do I disable it?
Thanks
|
|
|
|
|
Override the OnClosing event and set the Cancel memeber of that event argument to true. Rember that just disabling close button won't do the job, user can still use ALT + F4  .

He you can do it by 2 methods,
First one is just capture closing event of that form and make
e.cancel = true;
or second method is you disable closing button using following code,
You have to use win32 dll.
<br />
const int SC_CLOSE = 0xF060;<br />
const int MF_BYCOMMAND = 0x0;<br />
<br />
[System.Runtime.InteropServices.DllImport("user32.dll")]<br />
public static extern IntPtr RemoveMenu(IntPtr menuHwnd, int position, int flags );<br />
<br />
[System.Runtime.InteropServices.DllImport("user32.dll")]<br />
public static extern IntPtr GetSystemMenu(IntPtr hwnd, int bRevert);<br />
<br />
public static void EnableApplicationClose( System.Windows.Forms.Form form, bool val )<br />
{<br />
IntPtr menu = GetSystemMenu( form.Handle, val ? 1 : 0 );<br />
if ( !val && menu != IntPtr.Zero )<br />
RemoveMenu(menu, SC_CLOSE, MF_BYCOMMAND );<br />
else<br />
{<br />
form.Enabled = false;<br />
form.Enabled = true;<br />
}<br />
}<br />
<br />

I think I'll opt for method 1
|
|
|
|
|
Choose a window style without close button: FormBorderStyle.None
Having a button (or any GUI element) visible but turned off (without a visual clue)
is not good practice.

Yup! The entity that can not be used drives the user mad. 
|
|
|
|

and the dialog that can't be closed drives the user to kill process and uninstall.

You have to explain to them [VB coders] what you mean by "typed". their first response is likely to be something like, "Of course my code is typed. Do you think i magically project it onto the screen with the power of my mind?" --- John Simmons / outlaw programmer

I need to download data from multiple web servers using a web-service. Now the same web-service will be running on each of the servers. They will just have separate URL.
I am a new-comer in this web-service technology. I can only implement clients by first adding web reference to one of the servers. Developing clients without adding web reference seemed very complicated to me. So i want to add one reference and change the URL to access other servers.
Now my question is-
I will write the client code by adding any dummy web-server as web-reference. Then later when my client will run, this web-server might be shut-down, but it will keep calling this web-service by using other URL's. Will this create any trouble?
thanks

If you check out the client applications config file, there should already be a webreference url entry. Before deploying the applicaiton to the client, cant you just change this entry to the right URL?
Unless I understood your query wrong

Hi,
When i use this NVC.GetValues(KeyName), at times i am getting the following
error,
Void Copy(System.Array, Int32, System.Array, Int32, Int32, Boolean) :
Source array was not long enough. Check srcIndex and length, and the array's
lower bounds.
and
i am getting NullReferenceException when i use NVC.AllKeys with the
following message,
System.String BaseGetKey(Int32) ~ NRE ~ Object reference not set to an
instance of an object.
I cant predict the reason.
Here is my code snippet,
public void ProcessData(MyNVC procNVC)
{
if (procNVC.Count > 0)
{
try
{
string[] KeyArray = procNVC.AllKeys;
foreach (string skey in KeyArray)
{
string[] sVals = procNVC.GetValues(skey);
if (sVals.Length > 0)
{
sbuild.Append(skey + procNVC.Sum(sVals) + ';');
}
}
}
catch (ArgumentException oARG)
{
log.Info(oARG.TargetSite + " ~ ARG ~ " + oARG.Message);
}
catch (NullReferenceException oNRE)
{
log.Info(oNRE.TargetSite.ToString() + " ~ NRE ~ " + oNRE.Message);
}
catch (Exception oEXcpn)
{
log.Info(oEXcpn.StackTrace + " ~ EXCPn ~ " + oEXcpn.Message);
}
if (sbuild.Length > 0)
{
SendToClient(sbuild.ToString());
sbuild.Remove(0, sbuild.Length);
}
}
else
log.Info("No Elements in Collection:" );
}
With Thanks and Regards
Sakthi.

Hi,thanks for the quick response
Am using windows forms no ASP.NET.
to load the current row selected in the datagridview
int CustomerID = int.Parse(dataGridView1[dataGridView1.CurrentCellAddress.Y, 0].ToString());
customer customer = customerManager.GetCustomer(customerID);
then i fill the respective textboxes with data from that cell
txtcustomerID.Text = customer.CustomerID.ToString();
txtname.Text = customer.CompanyName;
the GetCustomer() method's definition is
public static customer GetCustomer(System.Int32 CustomerID)
{
string ConnectionString = "Server = (local);Integrated Security = SSPI ;Initial Catalog = pos";
string query = "Select * from CompanyProfile where CustomerId " + CustomerID;
DataTable dt = DataManager.ExecuteQuery(ConnectionString, query, "customer");
if (dt.Rows.Count == 0)
{
return null;
}
return new customer(dt.Rows[0]);
}
But when i run the Program and click in one of the cells,I get an error saying Input string is not in the correct format.
and the customerID value is 0 in that case though the value in the Database is 1.

What i want to do is,Get the value of the first cell with index 0 of the column CustomerID and use it in the query
which is "select * from companyprofile where customerID " +CustomerID;
