Hi,
Thanks for your reply. But in spite of setting the contextMenu for the tree view control, I am not able to see the menu upon right-click.
Sorry if my question is silly. I still do not understand how to associate this Menu to the right-click of the tree view item.

How to convert an uint32 integer to a byte[4]?
Moreover, put the byte[4] into a byte[] buffer.
Thanks!

Hello
You can try the next code:
uint i = 0xABCDEF12;
byte[] bytes = new byte[4]
{
(byte) (i & 0xFF),
(byte) ((i >> 8) & 0xFF),
(byte) ((i >> 16) & 0xFF),
(byte) (i >> 24)
};

I would like to write custom stringconverter for my own class so propertygrid can display correct string representation of the object.
but how to override method to convert string back to the object?
I wonder how microsoft does it with bitmaps or collections. Collection object is converted into the string as "(Collection)". but how this string is converter back to the actual collection? does anyone know what's the trick here?
thank you

Hi,
When the treeView control's nodes are right-clicked,
the selectedNode of the treeView won't be changed unless
it is a left-click mouse event.
My problem is that I associated context menu to the tree
nodes, so user just right click the node to use the context
menu, however the selectedNode isn't the node that the context menu
is launched.
So how can I set the selectedNode to the node that is right-clicked ?
Thanks

Subscribe to the MouseDown event of the TreeView and do this
if (e.Button == MouseButtons.Right)
{
Point point = new Point(e.X, e.Y);
TreeNode node = treeView.GetNodeAt(point);
if (node == null)
return;
treeView.SelectedNode = node;
Regards
Senthil

Hi,
I can't copy and paste plain from other sources into the RichTextBox control in C# application, but the TextBox control can, why ??
And is it possible to directly copy the stuff (e.g. image, text, table) from MSWord 2003 to the RichTextBox control ?
Thanks

You can only copy Text from Word. You can't copy tables or images because Word objects are not support by the RTB.

Maybe you know Excel 2003 enables you to set xml maps using menu command.You can select route,data/xml/xml source….,then the xml souce panel window will be displayed in the right screen.And you set xml maps by using click the xml maps button. So the problem is I want to use csharp code instead of this UI produce.
I try to find a event or a funcation in the Excel SDK. But I complete loss of hope, however the problem is very necessary and important.Can help me how to coding? Thank you very much!!

Here is an byte[] array.
I want to convert it to a stream , in order to use the Binary.Reader class.
Thanks!
|
|

Use the System.IO.MemoryStream class. You can create an instance of this stream with a byte[] array. Pass this instance to the BinaryReader class.

I have this set of code which is suppose to take a dataset, transfer it to a server via a web service, and then populate a databse with the information that is in the dataset however, I have an error where there appears to be no data in the dataset once it gets to the webservice, the data seems to be fine when it leaves the program, but is lost by the time it gets to the server.
userinfo is the WebService
here is the code for the program:
private void button2_Click(object sender, System.EventArgs e)<br />
{<br />
try <br />
{<br />
dg1.Tables[0].Rows[0]["COMPANYNAME"]=txtCompany.Text;<br />
dg1.Tables[0].Rows[0]["FAX"]=txtFax.Text;<br />
dg1.Tables[0].Rows[0]["PHONE"]=txtTelephone.Text;<br />
dg1.Tables[0].Rows[0]["POSTALCODE"]=txtZipcode.Text;<br />
dg1.Tables[0].Rows[0]["COUNTRY"]=txtCountry.Text;<br />
dg1.Tables[0].Rows[0]["STATEPROVINCE"]=txtState.Text;<br />
dg1.Tables[0].Rows[0]["CITY"]=txtCity.Text;<br />
dg1.Tables[0].Rows[0]["ADDRESS2"]=txtAddr2.Text;<br />
dg1.Tables[0].Rows[0]["ADDRESS1"]=txtAddr.Text;<br />
dg1.Tables[0].Rows[0]["Title"]=txtTitle.Text;<br />
dg1.Tables[0].Rows[0]["NAME"]=txtName.Text;<br />
dg1.AcceptChanges();<br />
MessageBox.Show(userinfo.SetUserInfo("uberducks2", dg1, UserID.GetValue("UID").ToString()));<br />
cmdApply.Enabled=false;<br />
}<br />
catch (Exception d)<br />
{<br />
MessageBox.Show(string.Format("Error During Runtime: {0}", d.Message));<br />
}<br />
}
This is the WebService Code:
public string SetUserInfo(string AuthID, DataSet dg1, string UserID) <br />
{<br />
if (AuthID=="*****") <br />
{<br />
try <br />
{<br />
string Name=dg1.Tables[0].Rows[0]["NAME"].ToString();<br />
string Title=dg1.Tables[0].Rows[0]["TITLE"].ToString();<br />
string Addr=dg1.Tables[0].Rows[0]["ADDRESS1"].ToString();<br />
string Addr2=dg1.Tables[0].Rows[0]["ADDRESS2"].ToString();<br />
string City=dg1.Tables[0].Rows[0]["CITY"].ToString();<br />
string State=dg1.Tables[0].Rows[0]["STATEPROVINCE"].ToString();<br />
string Country=dg1.Tables[0].Rows[0]["COUNTRY"].ToString();<br />
string Zipcode=dg1.Tables[0].Rows[0]["POSTALCODE"].ToString();<br />
string Telephone=dg1.Tables[0].Rows[0]["PHONE"].ToString();<br />
string Fax=dg1.Tables[0].Rows[0]["FAX"].ToString();<br />
Oconn.Open();<br />
string sqlcmd="UPDATE ACCOUNTUSER SET COMPANYNAME = '"+Company+"', NAME = '"+Name+"', TITLE= '"+Title+"', ADDRESS1='"+Addr+"', ADDRESS2='"+Addr2+"', CITY='"+City+"', STATEPROVINCE='"+State+"', COUNTRY='"+Country+"', POSTALCODE='"+Zipcode+"', TELEPHONE='"+Telephone+"', FAX='"+Fax+"' WHERE USERID='"+UserID+"';";<br />
SqlCommand brb=new SqlCommand(sqlcmd, Oconn);<br />
brb.ExecuteScalar();<br />
Oconn.Close();<br />
return "it seems to have worked.";<br />
} <br />
catch (Exception e) <br />
{<br />
return e.StackTrace.ToString();<br />
}<br />
}

Hello everyone. It's me again. I am working on this project and I want to save information to this datatable, and when the user clicks submit, it should be saved into another datatable. The only problem is everything gets reset, so I was wondering if anyone knew of a way for that not to happen.
Sincerely,
The Major Rager

Set the data in your grid inside a !IsPostback block.
if (!IsPostback)
{
grid.DataSource = .....
}

Hello, thanks for replying to my question. The thing is however, that I want the user to click the submit button, and when the user does click it, the information that is in the temporary datatable should be stored into another datatable. So that !IsPostback would not work for me.
Sincerely,
The Major Rager

Not using IsPostback is the reason your table is being reset every time. You can copy the data in your event handler, but unless you make sure it's not reset every time using ispostback, it will be.

Sori for the no-brainer commet but that's the 1st time i've seen Christian Graus post an actual code. Must be in a good mood...
But i totaly agree...by not using IsPostback, everytime you refresh the page everything resets to what you initialy set it to and thus does not display whatever changes you have made
