Hi,
there is a TextChanged event; you could attach a handler that replaces the entire
text by its uppercase equivalent.

Thank u luc pattyn ....
I have not followed your idea
I have written this in the keypress event and it worked
string str = e.KeyChar.ToString().ToUpper();
char[] ch = str.ToCharArray();
e.KeyChar = ch[0];

Hi,
yes that works for keyboard input, but not for pasted data (CTRL/V).

Is there a way to allocate disk space before copying a file in c#?
sample code will be greate help
Thanks
|

Are you talking about ensuring there is enough space on the disk to store the file?
Obviously, if there isn't enough space, any attempt to save it will throw an exception. You would have you free up sufficient space manually.

Hi,
haven't done this for a long time, but I would try and create a file, write a byte,
seek to the intended file size and write another byte; then you could rewind and
write the actual data, or close and overwrite any way you choose.

You can check all these yourself easily enough mate...
If you want to find out the exceptions a class throws then visit MSDN and look it up there, or you can simulate the exception and it will tell you the name of it when the program crashes.

Get to the dataGrid1.Columns[i] or dataGrid1.Column["name"] and set its width?

Urg, now I remember why I always use TableStyles in DG.
|
|
|
|
|
Just do this :dataGridView1.Columns[1].Width=X;",Maybe that's what you'll do.

I am so sorry that the DGV we used is defined by our company,you can change any column's width of the .net's DGV.

What is the exception thrown for:
"Object reference not set to an instance of an object." ??
Can someone wirte me a few lines of try catch code or a link which checks whether an array is uninitialised?

DateTime dt;
int n = dt.Days;
This will throw that error. It means that dt ( in this case ) is null.
Google will tell you all you need to know about arrays. At a guess, you've created an array of objects and are getting this error. Every object in that array is null and you need to call new on it before you can use it.

Actually I have a list view items which on runtime remains uninitialized..
And the code is in C++/CLI..
I am asking this here just for the reference..
How to handle it using the try catch blocks?
Is there any other way?

Hi,
at first use catch(Excemption exc) and watch it, then refine the catch.
Or read the documentation, it is begging for an audience.

try

I have a function which have return type DataRow and the parameters for the fucntion
are the parameters for the stored procedure.
I have to execute the Stored Procedure with given parameters and populate the datarow so that
the return will be the populated DataRow with the output of the stored procedure.
Again I have to retrieve data from the same datarow, perform some calculations in another function
which is going to use above datarow values, and give result in double or int datatype.
I have executed the Stored Procedure and now i m trying to store the data in the datarow
so that I can further retrieve it.
do anybody have idea how to insert and retreive data from DataRow in above case.
Thanks in advance,
