Hi,
I think I know all there is to know regarding how my binary file is assembled. However, there are unresolved issues:
1. Can you please explain how I can create a known-format image after loading the data I need?
2. Since every pixel is represented by 16bit (2 bytes and not 1), the only way I see for loading the image is loop for reading pixel-pixel BinaryReader. Any better suggestions? FileStream.read reads 1 byte at a time...
Thanks!

You can use a BinaryReader to easily read Int16 values.
Create a Bitmap object with the pixel dimensions of the image that you want to show.
Get the values from the 3D data and insert as color values in the Bitmap. An easy way to set the pixels in the Bitmap is to use the SetPixel method. A more complicated way (but somehing like 100 times faster) is to use the LockBits and UnlockBits methods and unsafe code (pointer operations) to write directly to the memory area for the Bitmap.
Despite everything, the person most likely to be fooling you next is yourself.

hi,
how i can retrive the selected items from the listbox at a time?
although i change the selectionmode with the multiple.
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)<br />
{<br />
<br />
TextBox3.Text = "" + ListBox1.SelectedItem;<br />
}
above code retrive the only one item even that i select the more then one items.

Listbox provides a collection which returns all the selected items.. and you can loop through that collection to get each selected item
ListBox.SelectedItems

SelectedItem retrieves the item with focus. SelectedItems returns a SelectedObjectCollection of all selected items. You can itterate through this.

ListBox1.SelectedItems...
|
|
|
|

try this :
string[] mySitems = new string[lb.SelectedItems.Count];
lb.SelectedItems.CopyTo(mySitems,0);
textBoxX1.Lines = mySitems;

but there is still problem like that
Error 1 'System.Web.UI.WebControls.ListBox' does not contain a definition for 'SelectedItems'
|
|
|
|
|
You never said it was a Web application - we all assumed you were using System.Windows.Forms.Listbox
I believe you have to loop through all the items in the list and test the Selected property.

yes..... i found solution which is following:
protected void Button7_Click1(object sender, EventArgs e)<br />
{<br />
TextBox4.Text = "";<br />
foreach(ListItem Isitem in CheckBoxList1.Items)<br />
if (Isitem.Selected == true)<br />
{<br />
<br />
TextBox4.Text += "\n" + Isitem.Text;<br />
<br />
}<br />
}

Hi Everyone,
Bit of an obscure question but i can't find an answer elsewhere online so i thought I'd post here.
I'd like to know if there's a way to retrieve a serial port description, as found in Device Manager, i.e. :
Communications Port (COM1)
I can easily get the serial port name using the static SerialPort method GetPortNames() (COM1, COM2 etc) but I cannot seem to find a way of getting the extra description information.
Id like to know because our support team regularly have to launch device manager to check which comm port our USB-Serial converter has been assigned and getting garage monkeys to launch device manager over the telephone is sometimes harder than it sounds!
Thanks for looking!
Chris.

as far as i know you cannot retrieve additional information about serial ports with the System.IO.Ports classes, but you can use WMI to get the information you need.
check out the win32_serialport class.

Is there any method to keep the assemblies in separate folder rather than putting it in the same folder where program is executed ? I am trying to deploy a windows application with dlls kept in a sub directory where application is installed. But it's throwing error which said "Assembly could not be loaded". Is there any other way to do this ?
|
|
|
|
|
AFAIK, The answer is NO. You have to keep the assembles either in GAC or in the same folder along with the executable.
There is a work around. By using System.Reflection.Assembly.LoadFile() or
System.Reflection.Assembly.LoadFrom() methods, you can load the assemblies from a different folder; but you may have to change the design and the application will suffer a little(regarding performance).

After replying to your post, I did some googling and came across this article. It is possible to keep the assemblies in a sub folder. You have to do the following.
1. Keep a config file (YourExe.exe.config)
2. Keep the following configuration settings
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="NewFolder"/>
</assemblyBinding>
</runtime>
</configuration>

Then why ask in the C# forum?

Hi,
I created a hash table with 3 elements.
hashtbl.Add(1, "aaa");
hashtbl.Add(2, "bbb");
hashtbl.Add(3, "ccc");
When I'm trying to modify the hash table as following,
hashtbl[2] ="xxx";
hashtable's length increased by 1.
After the above statement, hashtbl looks as following.
hashtbl[2, "xxx"]
hashtbl[1, "aaa"]
hashtbl[2, "bbb"]
hashtbl[3, "ccc"]
How can I restrict the hash table to add a new element with the same index, 2? I would like to get hashtable as below after the modification.
hashtbl[1, "aaa"]
hashtbl[2, "xxx"]
hashtbl[3, "ccc"]
Thanks in advance..

Is this using the built-in HashTable class? I would recommend using Dictionary<int, string>[^] instead. Your problem may have been due to some weirdness while boxing.

Thank you Vega02. Its worked and come to know about Dictionary class.

That is exactly the reason for the problem. The HashTable class uses reference types as identifiers, so if you try to use value types as identifiers, they are boxed first.
Each time you box the value 2, it becomes a new object on the heap, containing the value. As they are separate objects, they have different hash codes.
Despite everything, the person most likely to be fooling you next is yourself.
