C#, at least I think, is alot better than vc++6 since everything is soo easy to use and soo powerful. Smile | :)

So, you're saying that VB is better than C++?

I'm not saying that since I myself is a c++ proggrammer. It's just that it is said that C# combines the power of c++ with the ease of vb, though I know that C# has some issues, I think that this will probably erase mfc and visual c++ 6 though it will be alive, it won't be the preffered language anymore, just wait a couple of years and you'll see how it will progress.

It will do progress, but will not erase C++, ever!

Embed WindowsMediaPlayer Problem

Hi ,
I am trying to add a WindowsMediaPlayer Control in my app so that the user can play the audio file from my app page ! I have added the ref to WMPLib.dll.

My code is as follows:

AxWMPLib.AxWindowsMediaPlayer newMedia = new AxWMPLib.AxWindowsMediaPlayer();

ResourceManager resources = new ResourceManager(typeof(testControl));
newMedia.OcxState = ((AxHost.State)(resources.GetObject("newMedia.OcxState")));

newMedia.Enabled = true;
newMedia.Location = new Point(tX, tY);
newMedia.Name = tName;
newMedia.Size = new Size(tW, tH);
thisPanel.Controls.Add(newMedia);
if (tDefault != null) newMedia.URL = tDefault;

newMedia.URL = @"c:\myfile.mp3";

The last line newMedia.URL = @"c:\myfile.mp3" results in InvalidActiveXStateException. I know the filename is correct as I can play it from Explorer.

Any suggestions Confused | :confused:

!?!

Thanks,
Paul

Try converting the string to int with the Int32.Parse() method.

catch(Exception ex)<br />

}<br />

Good Luck !

I have Data in a typed DataSet and a Form to Edit it.
First Time I edit the Data with the form everything works fine. But if I want to reedit the Data, as I first changes something by the form everything freezes, means that I can't change data in any Control on the form. Even the OK, Cancel Buttons doesn't work anymore. I have to exit by the Close Button of the Form.

Any Ideas?

HOW TO SPREAD TEXT OVER COLUMNS IN A LISTVIEW IN C#

hi,Does anyone know how to spread text over columns in a listview in c#?

THIS is EASY IN C++ .you ONLY have TO SET the SetItemData Method of the CListCtrl to 0.
IF you WANT text TO BE DISPLAYED IN COLUMNS SET SetItemData to 1.

example:

m_ListCtrl.SetItemData(0,0); //this lines makes text spread over columns

m_ListCtrl.SetItemData(0,1); //text to be displayed column by column

how can this be accomplished in c#?

thanks

I personally haven't worked with ListView controls in C#, but I did a quick search in MSDN and found a property called "Tag" in the ListViewItem class which may serve your purpose.

Wait Cursor

Joel Matthias16-Sep-03 9:52

16-Sep-03 9:52

Has anybody determined how to set the cursor to a wait cursor during a long operation where Application.DoEvents() is being called (and thus allowing .NET to reset the cursor to that set for the control the cursor is currently over).

The only solution I have found is to set the current cursor of every control to the wait cursor, but what a pain.

Thanks - Joel

Selected Checkbox...

Hi.

i have a few checkboxes on my form and i want to show a simple messagebox when one of those checkboxes are checked. how can i do this dynamically?

for instance, instead of writing an if statement per checkbox, like this:

if(checkbox1.checked = true)<br />
{<br />
  MessageBox.Show("checked");<br />
}

write it dynamically, like this:
(the <selected checkbox=""> is the name of the selected checkbox)

if(<selected checkbox>.checked = true)<br />
{<br />
  MessageBox.Show("checked");<br />
}

i know this is pretty easy for all you guru friends out there. Smile | :)

Thanks,

.gonad.

I'm not sure if I understand you, but you can maybe use first parameter of your event handler method (sender). You have to set same function as event handler for all checkboxes.

private void checkBox1_CheckedChanged(object sender, System.EventArgs e)
{
  CheckBox checked=(CheckBox)sender;
  // checked is checkbox that was just checked/unchecked

}

Hi.

Thanks for your help. this worked exactly as you said, but i do have a queston.

Can you explain what the
(CheckBox)sender
is specifying? also, can i use this for a textbox, or other controls, as well? for example,

TextBox tb = (TextBox)sender;

I'm new at this stuff, can't you tell?

Thanks again.

.gonad.

First parameter (sender) of event handler is affected object.
it is passed as object so you need to cast it to correct type (Button / CheckBox etc..).
So when you have event handler for Button, sender is button user clicked on. If you have event handler for TextBox, sender is this TextBox.

In my code: I create EmployerClass

I want the EmployeeCollections can have a group of employees order by last name and first name. I can access it like Employees[i](int i) or Employees[name](string name = lastname+" "+firstname).

Can anyone please tell me how to do that?

Thanks in advance!

Need help with winforms treeview control

16-Sep-03 6:26

I want to populate a winforms treeview control from a relational table without xml in c#.net. I am new to c#, so please bear with me. I set up the oracle connection, dataadapter, fill etc. The code is given below.
My problem is that I have put messagebox and see that
this.treeView1.Nodes.Add(nodeAuthor); seems to add the nodes, but when the program completes and displays the form, I do not see the group_desc populated at all. I did not add anything manually in the Nodes property in Treeview. Please help!!!

this.treeView1 = new System.Windows.Forms.TreeView();
this.oracleConnection1 = new System.Data.OracleClient.OracleConnection();
this.oracleDataAdapter1 = new System.Data.OracleClient.OracleDataAdapter();

this.oracleConnection1.ConnectionString = "the connection strings"; string strSQLAuthors = "SELECT GROUP_MASTER.GROUP_DESC " +
" FROM " +
"GROUP_MASTER ORDER BY GROUP_MASTER.GROUP_DESC ";

TreeNode nodeAuthor;
DataSet ds;

//Create the Connection and the DataSet object, and then open the connection.

ds = new DataSet();
oracleConnection1.Open();

oracleDataAdapter1 = new OracleDataAdapter(strSQLAuthors, oracleConnection1);
oracleDataAdapter1.Fill(ds, "GROUP_MASTER");

//Populate the TreeView from the DataSet.
foreach (DataRow rowAuthor in ds.Tables["GROUP_MASTER"].Rows)
{
nodeAuthor = new TreeNode();
nodeAuthor.Text = rowAuthor["GROUP_DESC"].ToString();
this.treeView1.Nodes.Add(nodeAuthor);
}

//Clean up.
ds.Dispose();
oracleDataAdapter1.Dispose(); oracleConnection1.Close();
oracleConnection1.Dispose();
