Hello there,
probably an easy thing but I can`t seem to find it right away...
How can I know wether the caps lock or num lock key is pressed when my form is loading (without having to wait for a key press event)?
Thanks for your help

Try this:
short value = GetKeyState((int)Keys.CapsLock);<br />
bool CapsLockIsOn = (value & 0x0001) != 0;
using the Interop:
[DllImport("User32.dll")]<br />
private static extern short GetKeyState(int nVirtKey);

Hello once again!
I was wondering why i cant seem to add data to my datarow. here's the code snippet im hoping if you guys could help me out on this one...
DataTable dt = new DataTable();
string[] arrEmpIDs = strEmpID.Split(',');
for (int q=0; q<arrEmpIDs.Length; q++)
{
DataRow dr = dt.NewRow();
dr[q] = objDSPHContribRep.fgetEmpPhilHealthInfo(arrEmpIDs[q]);
dt.Rows.Add(dr);
}
return dt;
the array holds 10 strings and the function works fine (database retrieval). Well the program hangs before dt.Rows.Add(dr); and im totaly clueless why.
An advance thanx for all your posts! Kampai!!!

Looks like you are in an infinite loop - is this what you are trying to do?
DataTable dt = new DataTable();
string[] arrEmpIDs = strEmpID.Split(',');
DataRow dr = dt.NewRow();
for (int q=0; q < arrEmpIDs.Length; q++)
{
dr[q] = objDSPHContribRep.fgetEmpPhilHealthInfo(arrEmpIDs[q]);
}
dt.Rows.Add(dr);
return dt;

Hi! Thanx for the post!
Im not arguing or anything i was just wondering if i remove
dt.Rows.Add(dr);<br /> from the loop won't the program just add 1 long row instead of 10 short rows? oh yeah and since the program originaly hangs at dr[q] = objDSPHContribRep.fgetEmpPhilHealthInfo(arrEmpIDs[q]); upon debugging what would prevent it from stalling this time? pardon me for asking so much questions im still new at this and im thankful for al your helps

Hi Friends,
I am creating MDI(Multiple Document Interface) windows application. In the starting I show a login form while my main Menu of the parent form is disabled(I had set enabled property of menu items to false).
After successful login, I want to enable the Main menu items.
The problem is that I am unable to access the enabled property of the menu items of my main menu from my code.
Plz suggest the way to access the Enabled property of menu items.
Thanks,
Sandeep

Huh? Why is that so?
Alternatively, you could try leaving the menu items enabled by default and making the login dialog modal.
Cheers,
Vikram.

I want that in the starting, the user will not see any menu item enabled and when the child form(Login form), the login button is clicked In that I could apply the logic that if the logic is successful, then the menu items will be enabled at run time.
I want to access the enabled property of the menu of Parent form in the Login button click event of the child form.
Thanks,
Sandeep

#1 If the login dialog is made modal, how does it matter if the menu is enabled or not?
If you do not want to make the login dialog modal for some reason:
#2 Instead of trying to access the controls from the login dialog, why don't you do it once the dialog is closed? Depending on the return value (which I suppose you use to indicate login success/failure), you can enable the menu or anything you want.
HTH. 
Cheers,
Vikram.

I am sending u the whole scenario what I am doing.
In the declarations of Parent form, I am declaring:
private Form2 LoginForm;
public static int CustomerID;
and I had set "IsMdiContainer" property to true
In the Form Load event of Parent Form Form1:
this.LoginForm = new Form2();
LoginForm.MdiParent = this;
LoginForm.LayoutMdi(System.Windows.Forms.MdiLayout.Cascade);
LoginForm.Show();
Now in the button click event of Child form Login Form:
string Username = txtUserName.Text;
string Password = txtPassword.Text;
Form1.CustomerID = authenticateCustomer(Username,Password);
this.Close();
Thanks,
Sandeep

Sandeep, I saw your post below saying you were successful, but it never hurts to learn new ways... right?
From within the password dialog, this.MdiParent will give you a reference to your main form. You can use this to enable/disable the menu.
Alternatively, when you authenticate the user, set the form's DialogResult property to DialogResult.Yes or DialogResult.No. In your main form, after the line where you show the login dialog, check the return value and enable the menu again.
Cheers,
Vikram.

Thanks Vikram,
ur idea of making the login dialog modal worked very well. Initially I also had the same idea, but at that time I got the error, I dont remember what was that. I think i had not set IsMdiContainer prperty true at that time.
But now ur idea worked very well...........
Thanks,
Sandeep

What kind of file?
You can never execute a single file in a project. If you are creating a windows application, you can only execute the application itself. If you are creating a web application, you can execute any of the pages, but a page normally is the result of several files.

So, you want to execute just one cs file within one project? Is that right?
For what purpose? If it is just for testing then you might like to look at a testing framework like NUnit. While it won't execute the single file you can use it to invoke methods in the class in the file through a test fixture that you build.

NUnit comes with a number of samples to show you how it works, an a quick start tutorial[^]
You create a TestFixture class in a test assembly. This class will have a number of Tests. The test methods create the class you want to test, called the class-under-test (CUT) and invoke methods on it. You can then set up various assertions to see if the test ran as expected. If you are unsing NUnits GUI runner then you get a nice green bar if everything went okay. Or a red bar if it failed.

Hi all,
Someone say that, C# is stronger than VB.Net.
What do you think?
Can you help me to list the strength of C# that VB.Net hasn't.
Nice day.
Thanks.
