I am making a program were you type in your Xbox LIVE gamertag and it retrieves the info about it. I have most of it set up, but one thing I would like is to check if it exists or not. If you go to "http://live.xbox.com/en-US/profile/profile.aspx?pp=0&GamerTag=???" and replace the ??? with the textBox1 input, then if it exists, it takes you to the info. But, if it doesn't exist, it will still load the page like it exists, but then it will redirect to "http://live.xbox.com/en-US/profile/invalid.aspx". Is there a way to detect this redirection?

Also, I would like to retrieve some text on a certain location of a web page, could someone show how that is done?

Get the underlying combo of a datagridviewcomboboxcolumn

21-Aug-09 19:55

without javascript, i don't think that was possible. You coud try holding session data and inside you woud have variable that holds the pages visited

Hello

I'm trying to acceed the combobox property of a datagridview combobox column

I can do it using the EditingControlShowing event

// ***********************************************************************************
private void DgvKeys_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
  if (noEvent)
  {
    return;
  }

  ComboBox combo = e.Control as ComboBox;
}

But I need to acceed directly any combo in some column without having to waint an event on it !
To set the combo selected intex for example

I was trying this but it does not work !

DataGridViewComboBoxColumn cby;
cby = (DataGridViewComboBoxColumn)DgvKeys.Columns["Region"];
cby.SelectedIndex = cby.FindStringExact(combo.Text);

Any idea ?

Can you describe in more detail the circumstances when you would want to do this?

Thank you Henry

"Can you describe in more detail the circumstances when you would want to do this?"

Good question !

I have three combobox column on single row (one and only one)

Those three combo are binded to three different tables
There is a logical relation berween those tables

If the user select a value in the third combo I want to show the related value in the first and second cell

So I'm trying to force the values of two cell but it doesn't work
I'm trying this

If I change the appellation Column

Pays must shows "France"
And Region must Show "Bordeaux"

But Pays remain empty !!
I thought it was because I also have to change the selected item of the combo ??

// ***********************************************************************************
private void DgvKeys_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
  if (noEvent)
  {
    return;
  }

  ComboBox combo = e.Control as ComboBox;
  if (combo != null)
  {

    combo.DropDownStyle = ComboBoxStyle.DropDown;
    combo.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
    combo.AutoCompleteSource = AutoCompleteSource.ListItems;

    combo.SelectedIndexChanged -= new EventHandler(ComboBox_SelectedIndexChanged);
    combo.SelectedIndexChanged += new EventHandler(ComboBox_SelectedIndexChanged);
  }
}

// ***********************************************************************************
private void ComboBox_SelectedIndexChanged(object sender, EventArgs e)
{
  noEvent = true;
  ComboBox combo = (ComboBox)sender;

  if (combo.SelectedItem == null)
  {
    return;
  }

  DataRowView cRowV = (DataRowView)combo.SelectedItem;
  DataRow cRow = cRowV.Row;


  if (combo.DisplayMember == "Appellation")
  {
    DgvKeys.Rows[0].Cells["Pays"].Value = "France"; // = GetPaysName(cRow["PaysID"]);
    DgvKeys.Rows[0].Cells["Region"].Value = "Bordeaux"; // GetRegionName(cRow["RegionID"]);
    curApel = cRow["Appellation"].ToString();
    curApelID = Tools.GetInt(cRow["ApelID"]);
    noEvent = false;
    return;
  }
}

Hello !

I've just finded out that a part of the problem seems to come because I've defined a Value Member to my ComboboxColumn

If I remove the assignation of the valuemember I can force the value of the cell without problem ???

Hello,

I am wondering if there is some functionality with the upper right exit button when it is pushed. I need to do a check to make sure that a button was pushed (save button) before they close the browser. I wasn't sure if there was some code I could run in the code behind to do this or not. Thanks!

Try these:

string ConnStr = @"Data Source=.\SQLEXPRESS;Database=Master;Integrated Security=True";
SqlConnection mycon = new SqlConnection(ConnStr);
SqlCommand mycom = new SqlCommand("sp_detach_db", mycon);
mycom.CommandType= CommandType .StoredProcedure ;
mycom.Parameters.Add(new SqlParameter("@dbname", SqlDbType.NVarChar,50));
mycom.Parameters["@dbname"].Value = "mydb";
mycon.Open();
mycom.ExecuteScalar();
mycon.Close();

What was not pointed out is that you cannot detach a database the your using. You have to execute the detach sp connected to the master db in SQL Server.

Message Resource file version info

cturn21-Aug-09 6:03

21-Aug-09 6:03

How can you add the usual AssemblyInfo data (version etc) to a Message Resource file?

I have a Message resource DLL - created via the method described in article "Using MC.exe, message resources and the NT event log in your own projects" (by Daniel Lohmann) How do I get version info into that DLL?

Saksida Bojan21-Aug-09 6:26

21-Aug-09 6:26

Assembly myAssembly = Assembly.GetExecutingAssembly();
AssemblyName myAssemblyName = myAssembly.GetName();
MessageBox.Show(myAssemblyName.Version.ToString());

This code sample is for current rrunning app. Just load external Assembly

cturn21-Aug-09 6:34

21-Aug-09 6:34

I appreciate the response, however what I am looking for is how to get the version info *into* the DLL. The method I used to create the DLL did not embed any version info.
Method:
mc -u customdefs.mc
rc -r -fo customdefs.res customdefs.rc
link -dll -noentry -out:customdefs.mc.dll customdefs.res /MACHINE:X86

Is it possible to somehow compile an AssemblyInfo.cs file and link it into the DLL?

Saksida Bojan21-Aug-09 7:13

21-Aug-09 7:13

Sorry i missread it. I did check the article and i noticed it is in C++? Is your dll in C++? If so, you can't include or Link any C# files into native dll.

My DLL is a message resource file - the source was .mc file format (event log message text).

are you saying this Message Resource file is stand alone?

Adding that version code to my .rc file then compiling and linking does put it into the DLL (I can see it with Notepad) but the DLL's Property page still has no Version tab. Looks like it may not be recognized as version info.

Hello!

How can i wirte this code into a switch an case?

switch(get)

if (get.Contains("rHerunterfahren"))<br />
                    {<br />
                        string[] get_Split = get.Split('~');<br />
                        int zeit = Convert.ToInt32(get_Split[1]);<br />
                        System.Diagnostics.Process.Start("shutdown", "-s -t " + zeit.ToString());<br />
                    }

21-Aug-09 6:00

You can't. Or rather, you can, but it'll make the code even more complicated. A switch case tests the switch statement and provides multiple paths of execution. Yours only has two - true and false.

Incidentally, if that's related to the code you last posted, your design is a little off. Sending commands in plain text over a stream isn't the best way to go about remote-controlling a computer.

If I may question your logic for a second ...
If get_Split is an array of strings why not

System.Diagnostics.Process.Start("shutdown", "-s -t " + get_Split[1]);

?

The parse to int and then converting to string seems a little silly in context.
