Show me the code you are using for setting form background and retrieving it to store in database.

Are you storing the image or the path of the image?

If you are storing the image.. then do this.

Image im = Form.ActiveForm.Image;
and then save the image...

If you are storing the path.. then just store it in string Smile | :)

Thanks.

How to update databinding property

Hy all.

I have 2 controls binded to one data source

<br />
<br />
this.LookUpEditor1.DataBindings.Add(new System.Windows.Forms.Binding<br />
"EditValue",this.my_BindingSource, "ID", true));<br />
this.LookUpEditor1.ValueMember = "ID";<br />
this.LookUpEditor1.DisplayedValue = "Name";<br />
<br />
<br />
this.LookUpEditor2.DataBindings.Add(new System.Windows.Forms.Binding<br />
"EditValue",this.my_BindingSource, "ID", true));<br />
this.LookUpEditor2.ValueMember = "ID";<br />
this.LookUpEditor2.DisplayedValue = "NameSynonym";<br />
<br />
<br />

DataSource record has 3 fields "ID", "Name", "NameSynonym"
problem here: when i change value in first combobox it should changed in second and vice versa.

How i can implement this automatically with out using events and explicit property set
as what:

<br />
LookUpEditor1_onValueChanges(...)<br />
{<br />
   LookUpEditor2.EditValue =    LookUpEditor1.EditValue;<br />
<br />
}<br />
<br />
LookUpEditor2_onValueChanges(...)<br />
{<br />
   LookUpEditor1.EditValue =    LookUpEditor2.EditValue;<br />
<br />
}<br />

I am working on windows application with c#.net .
I am using FTPwebreuqest class for upload file on ftp.it works fine when there is no proxy between application and internet. but it doesn't work in proxy.

FtpWebRequest reqFTP;
if i use reqFTP.Proxy=new webproxy("proxyservername",port);
then it will display error message "FTP command doen't support in HTTP proxy".

my code is like this

FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create("ftp://uri");

reqFTP.Credentials = new NetworkCredential("username", "pwd");

reqFTP.KeepAlive = false;

reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
reqFTP.UseBinary = true;
reqFTP.UsePassive = true;
int buffLength = 2048;

byte[] buff = new byte[buffLength];
int contentLen;

FileStream fs = fileInf.OpenRead();

Stream strm = reqFTP.GetRequestStream();

contentLen = fs.Read(buff, 0, buffLength);

while (contentLen != 0)
{
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
prbUpload.Value += contentLen;
}

strm.Close();
fs.Close();

Any one help me about proxy settings in FTPwebrequest

.Net remoting, registering two channel? how???

Hello,
I've got an application that needs to create 2 remote object (CAO type), I init them into businness logic level:

<br />
private void InitNetRemotingProxy()<br />
    {<br />
      myDataProxyAccess = new ProxyDataAccess(idCup, idSeason, idMatchCode);<br />
      myDataProxyAccess.InitNetRemotingClient("Normal");<br />
<br />
      myDataProxyAccessForLev1 = new ProxyDataAccess(idCup, idSeason, idMatchCode);<br />
      myDataProxyAccess.InitNetRemotingClient("Lev1");<br />
    }<br />

and here's where the init is done

 <br />
public void InitNetRemotingClient(string type)<br />
{<br />
  string remotingConnection = system.Configuration.ConfigurationManager.AppSettings["serverAddress"];<br />
      string tcpPort = (type!="Lev1") ? System.Configuration.ConfigurationManager.AppSettings["tcpPort"] : System.Configuration.ConfigurationManager.AppSettings["tcpPortLev1Stat"];<br />
<br />
      string requestService = (type != "Lev1")<br />
                                ? System.Configuration.ConfigurationManager.AppSettings["requestServiceName"]<br />
                                : System.Configuration.ConfigurationManager.AppSettings["requestServiceName2"];<br />
      string sb = String.Format("tcp://{0}:{1}/{2}", remotingConnection, tcpPort, requestService);<br />
<br />
      <br />
      try<br />
      {<br />
RemotingConfiguration.IsRemotelyActivatedClientType(typeof(DBHelper));<br />
<br />
        IChannel ic = new TcpChannel(Convert.ToInt32(tcpPort));<br />
        int i = 0;<br />
<br />
        ChannelServices.RegisterChannel(ic, false);<br />
          RemotingConfiguration.RegisterActivatedClientType(typeof(DBHelper), sb);<br />
<br />
        myDBHelper = new DBHelper(idCup, idSeason, idMatchCode);<br />
      }

on the second call, the one myDataProxyAccess.InitNetRemotingClient("Lev1"); I get an exception at ChannelServices.RegisterChannel(ic, false);, the exception is : Message = "The channel 'tcp' is already registered.".

It's not possible to create 2 channel? Where I do wrong? The tcpport and requestServiceName are different for the two calls.
Please help me, thanks

I've fixed it, I've used:

 IDictionary pros = new Hashtable();<br />
        pros["port"] = tcpPort;<br />
        pros["name"] = type;<br />
<br />
        IChannel ic = new TcpChannel(pros, null, null);

and I had to substitute RemotingConfiguration.RegisterActivatedClientType(typeof(DBHelper), sb); with RemotingServices.Connect(typeof (DBHelper), sb);

Seems to work, do you know if there's still something I've to do?
Thanks

Hi,
I have developed an user contol in C#.NET 2.0 and this control uses MSHTML.dll COM library. Now, how will I know if this control will run on x64 platform. Moreover, what should I do in onder to make it portable for x64 platform ?

Regards

Change platform target from AnyCPU -> X64 which will compile application in X64. I think it's only available with .NET 2.0. I think the only difference will be large stacks are used in X64 mode by the compiler.

HI,
Thanks a lot for your help. Will there be any issue if my control depends on a COM dll ? I used MSHTML.dll and I dont know if this dll will run on x64 platform.

HelpRequested event

Hans Ruck25-Oct-07 19:41

25-Oct-07 19:41

Hi,

I have a Windows form with a button on it. I have enabled the HelpButton property of the form and I have implemented the HelpRequested event for the button.

Everything works fine as long as the button stays enabled. When disabled, the contextual help request simply doesn't work.

Is there any workaround for this behaviour? Is it supposed to be by design?

I tried this and it worked for me. How the help button is disabled ?

Thank you for the answer.
Just set the Enabled property of the button to false...

Yes it fired the events in disabled mode too. I think you are missing something.

Are you using the 2.0 Framework?

No 1.1 . How come you came to know that it's not working ? Can you show me the helprequested event code ?

Hans Ruck25-Oct-07 20:56

25-Oct-07 20:56

There is nothing special with the case:

private void button1_HelpRequested(object sender, HelpEventArgs hlpevent)
{
    MessageBox.Show("ok");
}

this.button1.HelpRequested += new System.Windows.Forms.HelpEventHandler(this.button1_HelpRequested);

I tested it on both of the frameworks (1.1 and 2.0) and still with the same result.

It's firing form's help event even though it's disabled. But it's not firing button's help event when it is disabled. I came to know that this is the default behavior.

OK, thank you.
It's better this way rather than not firing anything at all... Hmmm | :|
