Hi,
here is the syntax,
MessageBox.Show (IWin32Window, String, String)
what is the actual purpose of IWin32Window interface, Can i use this close the message box if the user not reponding for certain period of time,
my requirement is when the user clicks logout button on my application. i have manually close the already displayed messagebox and have to show the login screen. Is there any option to manually(thru code, as like as user pressed cancel button on the messagebox) close the message box.
Note: Here iam not talking about timeout messagebox, i want to manually close the message box.
Thanks and Regards,
Srini

IWin32Window is used to display message box infrontof specific control
e.g.
you have two forms form1,form2. and if you want to disply your message in front of other form . so simple pass the object of that form in the MessageBox.Show(); function

Are you looking for code or for an existing app? If the latter, you're in the wrong forum.

Sir,
In VB.Net The keyword Redim is used to modify the array at runtime.I have an array in C# .Now the problem is , i need to modify the array at runtime .How can i implement that?
Please help.
Thanks

Modify in what terms?
Increase the size or something else
If you want to increase the size u better use the Arraylist which
grows dynamically.

ok Sir , I will use theArrayList.Can u please give an example that illustrates how to dynamically increase decrease the array size using ArrayList.
Thanks
|
|
|
|
|
You just have to go on adding items to the arraylist
e.g.
ArrayList arrList = new ArrayList();
//some code
arrList.Add(item);
the above line adds an item to the arraylist
now if you want to decrease the size u can remove the unwanted item
arrList.Remove(index);
Hope u get it right..
Thanks & Regards,
Pramod

if you want to flush your values in the array use
myArray = null; // redim
if you want to just resize your array use
array.resize ( ref myArray, (int)myArrayNewSize); //redim.preserve
It is Good to be Important but!
it is more Important to be Good

I am trying to get a string from a database. The code for that works fine. I next want to add those strings to an array. This is where the problem occurs. What am I doing wrong?
for (int i = 0; i < arrayLevels.Length; i++)<br />
{<br />
int iLevelOridinal = rdr.GetOrdinal("Level");<br />
string szLevel = rdr.GetString(iLevelOridinal);<br />
<br />
arrayLevels[i] = szLevel;<br />
}
The error is:
Cannot apply indexing with [] to an expression of type 'System.Array'
I understand the error but do not know how to fix it, all help would be great!

Try this
string[] arrayLevels = new string[2];
Hope that works for you.

It looks like you are trying to access an array but you are using a type called System.Array. When you declare an array like so
byte[] arrayOfBytes = new byte[1000];
arrayOfBytes will implicitly inherit the type System.Array. arrayOfBytes is not of type System.Array, it is of type byte[]. It seems like you are attempting to access a type of type System.Array but for you to access it with indexing it would have to be an array of System.Array.
System.Array[] arrays = new System.Array[10000];
If you are going to use the System.Array type use the method GetValue
myArray.GetValue(index);
I recommend you use the conventional array syntax as it is much faster and good coding.
string myArray = new sring[100];
