I want to open e web from my C# aplication but i need to autentificate with a proxi
how can i do it
|

Assuming you're using WebClient and your proxy is using basic authentication, add the
Proxy-Authenticate[^] field to the Headers collection.
string base64 = Convert.ToBase64String(Encoding.ASCII.GetBytes("<username>:<password>"));
webClient.Headers.Add("Proxy-Authenticate", "Basic " + base64);
Or, you can use the NetworkCredential class to do it for you.

Hi,
I am trying to create an application which receives data from the network (probably a ZIP file) and write the content of network stream to the a LOCAL File... i can receive data and i can echo it out the console as well... i can write a file... but when i open up the file ... it has no content... what am i doing wrong?
here is the code:
private void readFile(int filesize)
{
try
{
FileStream fout = new FileStream(this.m_backupFileName,FileMode.CreateNew,FileAccess.Write);
NetworkStream ns = new NetworkStream(clientSock);
long rby=0;
int totalRecv=0;
//loop until the full bytes have been read
while( rby < filesize )
{
byte[] buff = new byte[1024];
//read from network stream
int i = ns.Read(buff,0,buff.Length);
Console.WriteLine(Encoding.ASCII.GetString(buff));
fout.Write(buff,0,i);
totalRecv += i;
rby = rby+1;
}
//done with reading
fout.Close();
//clientSock number of bytes
Console.WriteLine("Sending Num of Bytes");
clientSock.Send(Encoding.ASCII.GetBytes("DONE " + totalRecv.ToString()));
//get server's response
byte[] buf = new byte[128];
string resp = "";
clientSock.Receive(buf);
resp = Encoding.ASCII.GetString(buf);
if( resp == "OK" )
Console.Write("File Transfer Complete");
else if( resp == "ERROR")
Console.Write("Please Try Again");
}
catch(Exception ex) { Console.WriteLine(ex.ToString());}
}

I am using a typed dataset to store my data. I use a dataView to pull out what i need. the problem comes up in one case. I have a dataView that does not return what it should.
The DV init is:
<br />
DataView mDv = new DataView(ds.tblData, "(issent = false AND userIDN = " + userID + ") OR pending_draws = true","dataID", DataViewRowState.CurrentRows);<br />
If i run the same parameters in a SQL query it returns the correct rows. any ideas?

I am using the File.Create method to create a text file. My problem is that when I need to write to that file after it has been created I get the error message "The process cannot access the file "C:\2005 Sim R4 MedAlu Data\TN.txt" because it is being used by another process.".
|
|

|

You must derive a FileStream von the Create method:
FileStream fs = File.Create("C:\2005 Sim R4 MedAlu Data\TN.txt");
After that you can access the FileStream:
fs.Write("Your Data");
and finally close it.
fs.Close();

What code are you using? I suspect that you didn't call the Close() method right after you created the file. We can't do much without seeing the actual code you use. But anyways, here's a sample code I use when creating/writing text files:
FileStream <code>fs</code> = null;
string <code>tmpFile</code> = "C:\\sample.txt";
<code>fs</code> = File.Create(<code>tmpFile</code>, 1024);
<code>fs.Close();</code>
TextWriter <code>wr</code> = new StreamWriter(<code>tmpFile</code>);
<code>wr.WriteLine("Stuff 1");
wr.WriteLine("Stuff 2");
wr.WriteLine("Blah blah blah......");</code>
<code>wr.Close();</code>

I want to provide operators of my C# software the opportunity to change screen resolution to optimal settings (1024x768) for viewing this particular software. How do I change screen resolution (and maintain those changed settings), should the user opt to do so?
-- modified at 11:08 Tuesday 20th December, 2005
I should have added the following. The computer that will be running the program is, in this case, a dedicated machine. It's purpose is basically to run the software I'm developing. As such, it makes a certain sense to have the display settings optimal for the particular application-should the operator opt to set them that way. The operator is under no obligation to set the computer to those optimal settings and will have the option to not see the message box again after the initial run of the program.

You can do this by using P/Invoke to access the Win32 API from your C# code. Have a look at the ChangeDisplaySettings function and the DEVMODE structure. You will need to create the DEVMODE structure in your code and use DllImport to call ChangeDisplaySettings. The following link documents the DEVMODE structure.

I hope this helps.

What you're doing is not recommended, and, in fact, actively discouraged. Changing system-wide settings affects other applications that are running and also affects the layout of the desktop. Remember, Windows is a shared system, running multiple applications at once. You have to make sure you app works and plays nice with others. Changing system-wide settings so your app looks good, can make another app running at the same time look bad.
I know if you did that to my machine while I'm working in Maya at 1900x1440, I'd be heading straight for Add/Remove Programs and dumping your app.

In general, agreed. THe only time forcing a resolution should be allowed is in full screen mode, and then be sure to restore the settings when the user closes or alt-tabs out of your program.

I want to initiate the sending of a fax from within a C# application. I want to specify the file I want to send and then launch the Send Fax Wizard allowing the user to type in the fax number, the To, etc... Does anyone know how to do this? I noticed that Send Fax Wizard does not allow for attaching files. I was able to send faxes bypassing the Send Fax Wizard all together, but that's not entirely what I need.
Many thanks.

Thanks, but that's not entirely what I need. I need to use the Send Fax windows client and prompt the user for fax number, location, etc, etc. Any ideas would be greately appreciated.

try this

The link you've indicated has to do with sending a fax from a web page. All I want to do use COM-Object (faxcom.dll) to fax a PDF document. I want to "attach" the document to the object and fire up the Send Fax Wizard.

Hello everybody,
I want to change the cursors over all input controls (textboxes) on a form in a loop.
I tried something like:
foreach(TextBox tb in formclassname)
{
tb.Cursor = Cursors.No;
}
What's the right code to make the expected operation ?
Thank you in advance
Frank

Assuming you are trying to change the cursors from within the form that the textboxes are on, you can try something like this:
foreach (Control tmp in this.Controls)
if (tmp is TextBox)
tmp.Cursor = Cursors.Hand;
Or like this:
foreach (Control tmp in this.Controls)
if (tmp.GetType().Name == "TextBox")
tmp.Cursor = Cursors.Hand;

Polis

I would like to use a NumericUpDown and add the unit (feet, ...) after the number.
This is made by extending the NumericUpDown class and overriding the UpdateEditText method like that:
protected override void UpdateEditText()
{
//Let the base component format the number according to the different properties
base.UpdateEditText();
//Add the unit
base.ChangingText = true;
base.Text = base.Text + " " + unit;
base.ChangingText = false;
}
But the problem is when a user change a part of the text in the textbox,
the ParseEditText method cannot parse a string like "2 feet",
and i cannot override this method like it is not virtual or abstract in the base class (Why did Microsoft do that?).
Please help me to find a solution.
Thanks in advance

i am using com dll in my project which fires up event
code in vb is like this
Option Explicit
Dim WithEvents p As CLAMXLib.ClamEngine
Dim mresult As ClamResult
Private Sub p_OnScanComplete(ByVal result As CLAMXLib.IClamResult)
Set mresult = result
End Sub
in c#
CLAMXLib.ClamEngine p;
ClamResult mResult;
//now how will i catch events
code of class where i have to catch up event
public class clamresults
{
CLAMXLib.ClamEngine p;
ClamResult mResult;
public clamresults()
{
//
// TODO: Add constructor logic here
//
p=new ClamEngineClass();
p.Database.Path="E:\\projects backup\\ankitclam backup\\Clamtest\\database\\";
}
public string loadDatabase(string command,string dirpath)
{
if(command=="SCAN")
{
mResult=scanfile(dirpath);
}
else if(command=="RAWSCAN")
{
mResult=scanBuffer(dirpath);
}
else if(command=="CONTSCAN")
{
mResult=scandir(dirpath);
}
return mResult.Summary;
}
public ClamResult scandir(string dirpath)
{
p.Settings.ScanSupport=ClamSupport.Scan_Standard;
mResult= p.ScanDirectory(dirpath,0,ClamBoolType.False ,ClamBoolType.True);
return mResult;
}
public ClamResult scanfile(string dirpath)
{
p.Settings.ScanSupport=ClamSupport.Scan_Standard;
mResult=p.ScanFile(dirpath,ClamBoolType.True);
return mResult;
}
public ClamResult scanBuffer(string dirpath)
{
mResult=p.ScanBuffer(dirpath,ClamBoolType.False);
return mResult;
}
}
now how and where i will catch up events which will be generated from com dll
