A "Print Preview" on screen should look exactly like a "Print" on paper, that is its
purpose in life.

Hi guy
when u give the command to print preview,that's must be same as print .
so Try this way, i mean not come to printview do ur hide action something after do print preview go ahead.
Basically print view is like virtual print.

Good Day,
I have a FORM that has a background image (PNG), it covers the whole form.
Now, when I added a groupbox and set it backcolor to "Transparent", the expected thing did not happen.
The groupbox got the color of my Form (Form.BackgroundColor).
Is there anyway to force the groupbox to display the background image? Not the backgroundcolor?
Thanks,
Ian

I think you need to set a style to support transparency. Even then, I'm not sure if it will work, or if you need to set the appropriate bitmap to the background of your groupbox.

Thanks for the reply.
I made it work already. What I did was, instead of making use of a background image, i just used a PictureBox and resize it to cover the whole form.
Then, i set the controls to transparent then added this code at form load.
foreach(Control Found in this.Controls)<br />
{<br />
Found.Parent=PictureBox1;<br />
Found.BackColor = Color.Transparent;<br />
}

i was trying to write the files on the network , during writing , i got the error that i don;t have the permissions to write the files in that folder.
Now the question is can i programatically ascertain whether i have the right to write the files in that folder.

How are you opening the file? Aren't you asking for ReadWrite access while opening? What does it return?

i get the exception if i don't have the write permissions in that network folder .That's why i want to check it in advance whether i have the write permissions in that folder.

I am asking you how you are opening the file? You would be specifying the access you want on the file while opening and the file open command should return you a value. If it's that hard to understand, show me the code that you're using to open the file.

I don't think you can check that without trying to create a file. Why not just use a try/catch to work out when this is the issue ?

It is working very fine in try catch .But i get there as exception, that i don;t have the permissions.
that's y i wanted to know this in advance.

Hi
I am converting some code from Java to C#.
RandomAccessFile class is used in Java application. What would be replacement of this class in C#.
Thank You
James

Just a FileStream, I'd have thought. They have a Seek method, which makes it random access, right ?

Hi,
I have issue converting sbyte[] to byte[] array. My function(actually third party dll) returns sbyte with negative values. My question is how to put this sybte[] info( contains info of image) in to httpResponse object which takes only byte[] array.
Response.Expires = -1;
Response.Buffer = true;
Response.ContentType = "image/gif";
byte[] mapContent=null;
sbyte[] shortContent=mapFormat.DrawMap(map);
Response.BinaryWrite(?????)----- takes only byte[] info..
Thanks...

Like this:
mapContent = Array.ConvertAll<sbyte, byte>(shortContent, delegate(sbyte s) { return (byte)s; } );
Experience is the sum of all the mistakes you have done.

Thanks.. It solved the issue now... I am doing conversion with 2s compliment. when i do it normally, negative values overflows and returns error message. I am using 1.1 version. Now I am getting maps..
for(int i=0;i< shortContent.GetLength(0);i++)
{
if(i==0)
mapContent=new byte[shortContent.GetLength(0)];
sval=shortContent[i];
if ( sval < 0 )
val = (byte)(256 + sval);
else
val = (byte)sval;
mapContent[i]=val;
}

Hi,
I'm trying to code a tetris game in a windows form.
I have a class named fallingobject and since in the tetris game there are 4 shapes of fallingobjects, I've created 4 instances of fallingobject class and added them to a array (named as objcts) of type : fallingobject
If for example next shape is square I'm going to need an instance of objcts[0] element and change the coordinates property of it in my functions. But I don't want to change the properties of the object in the array, I only want to change the properties of the instance, but it changes as well, when I write the following code:
<br />
fallingobject fllnobjct;<br />
Random r = new Random();
fllnobjct = objcts[r.Next(4)]; <br />
It's probably because I'm referencing the object in the array and it's my mistake, but when I do the following:
fallingobject fllnobjct;<br />
Random r = new Random();<br />
int rndm = r.Next(4);<br />
fllnobjct= new fallingobject (objcts[rndm].coordinates,objcts[rndm].colour);
it happens to me when I write the code above, I'm creating a new instance with properties of the array element as parameters so the array element shouldn get affected by the changes in the instance but same thing happens again..
how should I define the instance so that it doesn't change its mother class?

This is an issue with the copy constructor in the fallingobject class. Try making fallingobject a struct, if you can. Otherwise, impliment and use the clone method to make a copy of the object.
fllnobject . objcts[r.Next(4)].Clone();
