I think I might of figured out how to pass the list to the child form. By Adding a Public List<string> in the child form. WOrking on testing that But now I have a somewhat new question....
How do I have the child form return the result of Dialogbox.ok?
I have set the child form's ok and cancel button's dialog property to the ok and cancel property. But I am unsure how to pass that to the parent form.

That is wrong, when you add/delete to a list (which is an object) it still is the same list (i.e. the same object, the difference is it may contain some other items).
For the rest, I'm not going to study all that, it is way too much code for anything you may want to do. And AFAIK some of it will not even compile.

I figured out finally how to pass the array to the child and back...
Parrent Form:
using (frmpopupEmailRecipient popupVerifyEmailRecipients = new frmpopupEmailRecipient())
{
popupVerifyEmailRecipients.MyEmailTo = EmailTo;
popupVerifyEmailRecipients.MyEmailCC = EmailCC;
if (popupVerifyEmailRecipients.Show() == DialogResult.OK)
{
}
EmailTo = popupVerifyEmailRecipients.MyEmailTo;
EmailCC = popupVerifyEmailRecipients.MyEmailCC;
}
Child Form:
public partial class frmpopupEmailRecipient : Form
{
public List<String> MyEmailTo;
public List<String> MyEmailCC
}
Now optionally I would like for learning instead of just closing the frm... How do I modify the child form to return a dialogresult.ok value?

A Control (a Form IS a Control) offers the following methods amongst others:
public void Show()
public DialogResult ShowDialog()
and the MSDN page on ShowDialog clearly explains how the return value is determined.

You create a formula field with below code and drag drop that field into ur crystal report detail section below ur data field, I hadnt checked may be it will work..<br />
<br />
<br />
Global booleanVar flag:=true;<br />
Local stringVar print ;<br />
if flag then print :="__________________________________";<br />
flag=false;<br />
if flag=false then<br />
flag:=true;<br />
print :=""

I need to get informed about every incoming network connection in C#.
All examples I found on the web were client/server stuff.
But I don't have any clients.
I want to get notified about all incoming connections at all ports.
How does it work? Which class can I use? Are there any events?
Thanks in advance for any hints and help.

.NET doesn't have an event that handles all incoming connections. Some connections are even made without the Frameworks' knowledge!
You could dive into the Firewall API, I believe that all connections pass through there.

string message = Timetable(doc);

string timetableResult = "";

Output("Processing...");
using (StreamReader sw = new StreamReader(new FileStream("out1.xml", FileMode.Open)))

}
}
}
I can't seem to return a string, the error says :Could not load file or assembly 'RS232, Version=1.24.0.0, Culture=neutral, PublicKeyToken=515d87df384dcc81' or one of its dependencies. The system cannot find the file specified.
Please help.

Apparently, something in the code you are not showing is depending on a class in the RS232 library and that library cannot be found.
P.S. If the component from that library is a serial port and you are on .NET 2+, you could consider switching to the built in System.IO.Ports.SerialPort class.

Hi
i have a simple unBound field in my report designer named 'UnboundString1'.
i want to pass value to this field froom code, but i don't know how to do that. i also create a parameterField and use this code to pass value but nothing happened :
this.customersTableAdapter.Fill(this.northwindDataSet.Customers);
ParameterField myParam = new ParameterField();
myParam.ParameterFieldName = "UnboundString1";
ParameterDiscreteValue myDiscreteValue = new ParameterDiscreteValue();
myDiscreteValue.Value = "USA";
myParam.CurrentValues.Add(myDiscreteValue);
this.crystalReportViewer1.ParameterFieldInfo.Add(myParam);
this.CustomersReport1.SetDataSource((DataTable)this.northwindDataSet.Customers);
this.CustomersReport1.Refresh();
this.crystalReportViewer1.RefreshReport();
how to workaround this problem ?

Hi
i have a datagridview in a form that have a ComboBox column.
i want to send a value from an other form to datagridview combo box column.
i connected the combo box column to a table that show a member in Display Member
and return the Value Member but i dont know how to get the value in value member.
actually i lookin for something like SelectedValue in ComboBox Class.
how can i it?
thanks

The following code will get the value. You can ignore the fact that it is a DataGridViewComboBoxColumn for your purpose.
DataGridViewRow currRow = this.dataGridView1.CurrentRow;
this.txtValue.Text = currRow.Cells["CBColumn"].Value.ToString();
DataGridViewRow anyRow = this.dataGridView1.Rows[2];
this.txtValue.Text = anyRow.Cells["CBColumn"].Value.ToString();
DataGridViewCell currCell = this.dataGridView1.CurrentCell;
this.txtValue.Text = currCell.Value.ToString();
I have split the processing into two lines, and I would probably do this anyway because it is easier to understand. However, you could do it in one line, like this: (I have only shown the first one although you could do the same for all three)
this.txtValue.Text = this.dataGridView1.CurrentRow.Cells["CBColumn"].Value.ToString();
**NOTE**
'CBColumn' is the Name I have given to my DataGridViewComboBoxColumn, the Name property, not the HeaderText

Hi group,
I'm converting a large old C++ program to C#. It has lots and lots and lots of istream/ostream io. Is there an equivalent io capability in C#? Any suggestions on the most efficient way to do this.
Thanks /Mike

The demo edition of our 'C++ to C# Converter' will allow conversion of some of the C++ IO methods/operators. Console.Write and Console.Read are used in addition to some helper methods for conversion of 'cin'.

There are tons of stream classes in C#. You should perhaps buy a C# reference.
If your C++ program includes extensions to iostreams, you're probably looking at a full rewrite of how you approach things.

Thanks for the answers. Here is a code fragment I found here <http: www.java2s.com="" tutorial="" cpp="" 0240__file-stream="" performbothinputandoutput.htm="">
Is there c# support for this type of stream io?
<br />
#include <iostream><br />
#include <strstream><br />
using namespace std;<br />
<br />
int main()<br />
{<br />
char iostr[80];<br />
<br />
strstream strio(iostr, sizeof(iostr), ios::in | ios::out);<br />
<br />
int a, b;<br />
char str[80];<br />
<br />
strio << "10 20 testing ";<br />
strio >> a >> b >> str;<br />
cout << a << " " << b << " " << str << endl;<br />
<br />
return 0;<br />
}<br />

I have come across an interesting problem. If I have a DataSet which I've read from an XML file. Then I call WriteXML to my memory stream. If I try read it back into a dataset I get the following error "Root Element is missing"
here is some example code.
DataSet ds = new DataSet(); <br />
ds.ReadXmlSchema(@"C:\Foo\FooSchema.xsd");<br />
ds.ReadXML(@"C:\Foo\Foo.xml"); <br />
<br />
MemoryStream ms = new MemoryStream(); <br />
ds.WriteXml(ms); <br />
ds.ReadXml(ms);
Does anyone know why? or how I can use a DataSet to read directly from a MemoryStream?

The current position pointer of the memory stream is left at the end when you do the ds.WriteXml. You have to do something (apologies, no access to IDE right now) like ms.CurrentPosition = 0; before the the ReadXml to move it back to the start.
CCC solved so far: 2 (including a Hard One!)
|
|
|
|
|
In your example you try to read after the written data (MemoryStream position != 0).
You have to reset the read position of the memory stream.
MemoryStream ms = new MemoryStream();
ds.WriteXml(ms);
ms.Seek(0, SeekOrigin.Begin);
ds.ReadXml(ms);
|
|
|
|
|
Aah yes, silly me, I forgot about the pointer.
Thank you!
|
|
|
|

Keefb is coirrect, you have to rewind the stream, using:
if (ms.CanSeek)
{
ms.Seeek(0,SeekOrigin.Begin);
}
But be aware it may not work! You may well need ms.FlushFinalBlock() to ensure that last bit of data is written.
