To write bytes to a file:
FileStream fs = new FileStream("c:\\someFile.dat", FileAccess.Write);
byte[] bytes = new byte[numberOfBytes];
fs.Write(bytes, 0, bytes.Length);

Lets supose that I have 2 applications, one at C:\app1 and another at C:\app2. At application 2 I have 2 assemblies, app2-1.dll and app2-2.dll. App2-1.dll have a reference to app2-2.dll, so app2-1.dll needs app2-2.dll to work correctly. Ok, at my app1 I use the following code:
System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFile(@"C:\app2\app2-1.dll");
Type classType = assembly.GetType("app2-1.MyClass",true);
At this time I've an error. When my assembly app2-1 tries to call some method from my app2-2 that is referenced it doesn't find my app2-2.dll.
How to change my default assembly path when load it? something like this...
System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFile(@"C:\app2\app2-1.dll");
assembly.DefaultPath = @"C:\app2\";
Some Idea?
Tkx
PS: This property DefaultPath doesn't exist...

Hi,
Is there anyone can help me solve a problem with screen capture?
I found using bitblt to save image in main window I point to, will capture other image which on the top of this window. Is there other way to save main frame image even which is not on the toppest? Thanks in advance.

Yes. I read it. Let me clear my question. I want to save image in my own application window every 30 seconds for example no matter whether the user actives other applications. I don't think I can make any other window invisible which i may don't know it is on the top of mine, when i am trying to catch the image in my application window. So maybe I should ask this way, is there any way to catch image of one frame window which i specified? Just like I opened calculater and then opened explorer, may I catch calculater image when i know the window handle of calculater, but it is under the explorer window? Or maybe I didn't get the point of the article you told me...Can you tell me more..? Thanks

I am a newbie. I want to stream a video (.wmv) via TCP/IP (not webpage).
I am programming in C#.
- As I know, C++ should be used in Windows Media Format SDK, can it also be used in C#?
- Windows Media Encoder SDK can encode file for streaming, but can it also be used for streaming too?
-Any link can give me to study?
Thank You

Hello,
I am trying to convert the following c# into j# but I am having difficulties.
C#
e.Graphics.DrawString(listBox1.Items[e.Index].ToString(), e.Font, myBrush,e.Bounds,StringFormat.GenericDefault);
J#
e.get_Graphics().DrawString(listBox1.get_Items[e.get_Index()].ToString(),e.get_Font(), myBrush, e.get_Bounds(), StringFormat.get_GenericDefault());
However I get this error:
Cannot find field 'get_Items' in class 'System.Windows.Forms.ListBox'
Does anyone have any ideas?
Thanks,
Harold Clements

I'm no expert for J# (to be honest; I've never used it  ), but after taking a quick look I think the following could work:
e.get_Graphics().DrawString(listBox1.get_Items().get_Item(e.get_Index()).ToString(), ...

Here's my guess:
Brush myBrush = Brushes.get_Blue();
if( listBox1.get_SelectedItem() != null )
e.get_Graphics().DrawString( listBox1.get_SelectedItem().toString(),
this.get_Font(),
myBrush,
(float)e.get_ClipRectangle().get_X(),
(float)e.get_ClipRectangle().get_Y() );
I simplified a little, because I couldn't tell which overload you wanted; you seemed to want to pass a Rectangle where as it looks like a RectangleF is required in a couple of the overloads.

Thanks Stafan and Matt for your responses.
Unfortunately I am still getting compiling errors. Matt’s suggestion of : (float)e.get_ClipRectangle().get_X(), does not work as get_ClipRectangle() is not a member of ‘e’.
This is my whole method:
<br />
private void listBox1_DrawItem(Object sender, System.Windows.Forms.DrawItemEventArgs e)<br />
{ <br />
listBox1.set_DrawMode(DrawMode.OwnerDrawFixed);<br />
e.DrawBackground();<br />
Brush myBrush = Brushes.get_Black();<br />
<br />
switch (e.get_Index())<br />
{<br />
case 0: myBrush = Brushes.get_Red(); break;<br />
case 1: myBrush = Brushes.get_Orange(); break;<br />
case 2: myBrush = Brushes.get_Purple(); break;<br />
}<br />
e.get_Graphics().DrawString(listBox1.get_SelectedItem().toString(),this.get_Font(),myBrush,(float)e.get_ClipRectangle().get_X(),(float)get_ClipRectangle().get_Y());<br />
<br />
e.DrawFocusRectangle();<br />
<br />
}<br />
Any other ideas will be gratefully received.
Thanks,
Harold Clements

Awaiting for any solution.

hi every 1,
i'm working on a networking project "Simple Project" and i want to transfer files in this network how should i do this , i know a littel about sockets but i think that i can do it .. any 1 help please !!!
|

Hi
Look at the Socket.Receive and Socket.Send methods in the MSDN - they provide sample code for point-to-point connection transfer (TCP). One machine does Send/Recv and the other does Recv/Send.
Socket.ReceiveFrom and Socket.SendTo demonstrates datagram connectionless transfer (UDP). One does Send only and the other does Recv only.
The sockets buffer has a limited size typically max 64KB with UDP and much less for TCP, so with file transfers you will have to send it bit-by-bit, so you'll have to define a protocol that includes information such as 'this is block 1 of 23', and collate this on the receiving end into a single file.
You will also have to consider what happens if you miss a block - ie. wait for the next cycle, etc.

Hi
In c# program What you should do is store the field (i.e column name)of a xml schema file in an array . Then while looping thru’ your input name (a xml file say "first.xml" with a single column name same as the name as in the schema) you should find out where this column name lies in your input file (i.e the index. Could be 4th one). Then update the output file accordingly(write that column values from the xml file into the output xml file).How to do this. a coding help pls

Hi guys,
I'm really struggling with a problem I'm having with a datagrid.
Basically, I download a log of alerts in the form of an xml document and load them into a datagrid, all in string format.
The problem is that when I display the form the first cell in the grid is always selected. What I am looking for is some way of making the grid unselectable, or even just a way to deselect the cell when I display the form.
I am using a DataTable called alerts with 3 DataColumns called date,url and notes. This is the constructor code
InitializeComponent();<br />
date = new DataColumn("Date");<br />
date.ReadOnly = true;<br />
url = new DataColumn("URL");<br />
url.ReadOnly = true;<br />
notes = new DataColumn("Notes");<br />
notes.ReadOnly = true;<br />
<br />
alerts = new DataTable("Alerts");<br />
alerts.Columns.Add(date);<br />
alerts.Columns.Add(url);<br />
alerts.Columns.Add(notes);<br />
<br />
dataGrid1.DataSource = alerts;
I then have a test method in place to fill the grid
<br />
public void SetTestList()<br />
{<br />
for(int i=0;i<20;i++)<br />
{<br />
alerts.Rows.Add(new string[]{"Test "+i,"Test "+i,"Test "+i});<br />
}<br />
<br />
this.Refresh();<br />
}
Anyone have any ideas what I can do to sort this problem out?
Cheers
Mike

Hi,
I have written a word automation application in c#, using the 2003 word object model 11.0. I have tested it on my system and it works fine. When i copy the EXE and required dll's on to another system, i get a System.UnauthorizedAccessException. Considering that all i have written is a windows form, that attemps to create a word object and open a document, this is pretty unexpected. This exception occurs on creating the object itself.
But when i add the user with permissions to the DCOMCNFG Default Access, then i am able to create the word object. But on my own system the code works fine without the settings. Can anyone help me out here!!
Thanks and Regards,
Laks

My application logs its operation into a file.
As part of the application when an exception is thrown I am logging the exception.
The log shows the whole exception stacktrace and message in English and it’s fine.
However, when the application is installed on Russian Windows the exception messages (not the stacktrace) is logged in Russian.
How can I cause the exception to be written always in English?
I know that when I change the Thread.CurrentThread.CurrentUICulture to of the thread to CultureInfo.InvariantCulture just before the exception is thrown then the exception message is in English even on the Russian machine.
This solution forces me to change the CultureUI of the all the threads on creation and it’s not nice solution.

I am so poor in thin client application. So i can't able to help you in C#. But at the same time you can meet your goal using JScript. I know this is not an exact answer for your queary. But this is alternative for your queary.
<br />
<body><br />
<script language=jscript><br />
function CloseMe()<br />
{<br />
close();<br />
}<br />
</script><br />
<form id="Form1" method="post" runat="server"><br />
<button id="btn" onclick="CloseMe();"/><br />
</form><br />
</body>
