What I am trying to do is create a new picturebox everytime you left click on the screen and delete the one you are on when you left click on one.
This is the code I have.
if (c == panel1)
{
if (e.Button == MouseButtons.Left)
{
//Get picturebox from unUsedBoxes to Create a new box
int position = unUsedBoxes.Count - 1;
if (position >= 0)
{
System.Windows.Forms.PictureBox p = (PictureBox)unUsedBoxes[position];
unUsedBoxes.RemoveAt(position);
usedBoxes.Add(p);
p.Location = new System.Drawing.Point(e.X, e.Y);
p.Size = new System.Drawing.Size(100, 50);
p.Show();
p.MouseDown += new MouseEventHandler(mouseDown);
p.MouseUp += new MouseEventHandler(mouseUp);
p.MouseMove += new MouseEventHandler(mouseMove);
}
else
{
MessageBox.Show("You have exceeded the maximum number of selections", "Selection Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
}
else
{
if (e.Button == MouseButtons.Right)
{
//Delete box
usedBoxes.Remove(c);
unUsedBoxes.Add(c);
panel1.Dispose();
}
}
}
the code compiles but the picturebox is never created.

A control is most useful when you add it to some container...
|
|
|
|

I already have this code in the Designer
this.pictureBox1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
this.pictureBox1.Location = new System.Drawing.Point(0, 0);
this.pictureBox1.Name = "pictureBox1";
this.pictureBox1.Size = new System.Drawing.Size(100, 50);
this.pictureBox1.TabIndex = 0;
this.pictureBox1.TabStop = false;
And this code in the On Load
usedBoxes = new ArrayList();
unUsedBoxes = new ArrayList();
unUsedBoxes.Add(pictureBox1);
do I need to specify more than that a parent?

a control only "works" in a UI when added to the form's hierarchy of controls,
as in myForm.Controls.Add(myControl)
check this in the documentation, and in the code generated by Visual Studio's Designer !

Hey all !
First of all let me start by saying I'm new to C# and programming what so ever..
I have a Excel sheet that I read lines from. Each line has 15 cells with numbers between 1-70 of random combinations.
My purpose is to hash every single line to a single result. The result is stored in an array.
I'm doing so by performing XOR between the cells' content (casting them to bytes).
This also gives me the luxery of not having to deal with the order of the numbers.
However, here's the problem. I'm getting the same XOR result for different types of numbers (how obvious).
For Example:
13^17^21^22^23^25^26^27^29^31^46^53^55^60^63 = 61
5^9^14^20^27^28^32^35^38^41^43^50^58^61^62 = 61
Is there any better solution for doing what I want ?
Be very appretiative if someone could help me out ...
Thanks !

Hi guys! How can i count size of structure?
|
|
|
|
|
count size of each field and sum
|
|
|
|
|
Yes but if it possible to count it by one command?
For ex sizeof( structure_Name )

Have a look at Marshal.SizeOf().

Hi
Please find which Cause the problem
Response.Redirect("PrintQuote.aspx?Print=" + grdVwAgentQuote.SelectedRow.Cells[7].Text+" & Quote="+TextBox1.Text);
dataPrinting = adapterprinting.GetData(int.Parse(Request.QueryString["Print"].ToString()), int.Parse(Request.QueryString["Quote"].ToString()));
When i just call one querystring. Its Working Fine. But if i call both the QueryString Then the Null Exception is showing on the Print. But if i pass only Print as queryString its working Fine.Please advice to solve the issue.

When you try to read the value using the name "Quote", you will not find it as the name is " Quote".
Remove the extra spaces around &.
Also, you should use Server.UrlEncode to encode the values before you put them in the query string.

Can you send some Sample Code for Server.URLEncode. Because it gives error to me
Regards,

Example:
Response.Redirect("Page.aspx?something=" + Server.UrlEncode(someValue) + "&other=" + Server.UrlEncode(otherValue));

I'm wondering if a female read your question and knew the answer, but because of that exclusionary comment decided not to help you.

Thanks for your comment. And if I've offended any woman by what I said earlier, I'm sorry cos I didn't mean it in any way. So this goes for the women.

Does any one know how to get a remote web server to transfer its Certificate (X509Certifcate) to the local machine using Sockets? I need the public key from a given web server.

I know.
I have given up hope. I think I am going to the route of setting up an SSLSocket just to get the certificate information from the web server. This seems like a waste of resources to me.
