See here[^] for web services that will let you send SMS without needing a USB phone.
Not exactly what you are asking for, but it might help.

Is there a way to dynamically create controls using a For loop?
So for instance if you wanted 4 RichTextBox controls instead of writing lines a code for each control can you not use a loop to create them?
Something like:
for (int i = 1; i < 5; i++)
{
((richbox)i) = new System.Windows.Forms.RichTextBox();
}
So that you end up with 4 RichTextBoxes:
richbox1
richbox2
richbox3
richbox4
Any help appreciated..

Only if you want to keep your reference to them in an array, or you want to write ugly reflection code. If you create an ArrayList to hold them, then it's easy.

The best you can do is this:
RichTextBox[] richBoxes = new RichTextBox[4];
for(int i = 0; i < 4; i++)
{
richBoxes[i] = new RichTextBox();
}And you'll end up with 4 RichTextBoxes: richBoxes[0], richBoxes[1], richBoxes[2], and richBoxes[3].
I hope this helps.

Hi guys
thankx in advance
I am trying to craete a user control which has datagrid in it, I want to pass datareader to this control and load it accordingly and then hide the columns (by passing params again) which i dont want user to see.
I can see that my datareader is available in my User control but it doesnt load the data grid or throw any exception. I am using C# and ASP.NET for this.
Help is urgently required
.... this is the user control code behind.......
public partial class Data : System.Web.UI.UserControl
{
public SqlDataReader drVal = null;
protected void Page_Load(object sender, EventArgs e)
{
setGrid();
}
public Boolean setGrid()
{
try
{
if (drVal.HasRows)
{
dgDataGrid.DataSource = drVal;
dgDataGrid.DataBind();
drVal.Close();
return true;
}
else
{
return false;
}
}
catch (Exception ex)
{
Response.Write(ex.ToString());
return false;
}
}
}

Hi,
Just out of curiosity, is your datareader having data at the time you are trying to bind the reader to the grid.
If it doesnt have any data it may not throw an error as well as you wont see anything.
Let me know

I have a Form which references another form within the same namespace eg:
Form2 frm2 = new Form2();
Form2 needs to be opened more than once.
I open the form when a button is clicked with:
frm2.Show();
After closing frm2 and clicking on the button to open the form again I get the following error:
Cannot access a disposed object named "Form2".
I can get around this by using frm2.ShowDialog() only problem being that the second time the form is opening the layout is all messed up as though the controls were not disposed when the form was closed.
How can I ensure that the form can be opened multiple times??

It sounds like you're declaring frm2 within your click handler and then calling it again once the object has gone out of scope. My suggestion would be to promote frm2 to a local variable and then instantiate it in the constructor. Then, when you handle your button click event, you can call Show(). Try something like this:
public class Form1
{
Form2 myForm2;
Button myButton;
public Form1()
{
myForm2 = new Form2();
myButton = new Button();
myButton.Click += new EventHandler(myButton_Click);
}
private void myButton_Click(object sender, EventArgs e)
{
myForm2.Show();
}
}

This gives the same error.
I changed the code to match what you have.
If I use:
myForm2.ShowDialog(); instead of myForm2.Show(); it works only the layout of controls on the form are messed up. For example instead of one OK button there are two of them.

Hi
I did this:
Form2 frm2; // Class level variable
private void button1_Click(object sender, System.EventArgs e)
{
frm2 = new Form2 ();
frm2.Show();
}
And added a Form named Form2 and it works fine. Even you close the form2 and click on the button still it creates a new form.
Please let me know if I am missing something.

Yeah that works fine. Thanks for your help

The System.Web class has been deprecated in .net 2.0... So the email code I've been using no longer works.
After some tinkering, I got the System.Net class to send the email, however... It wont actually send the mail until I exit the program. Whats the deal with that?
The function finishes with no errors. I can wait and nothing happens. Then the moment I close the program, the email leaves my machine. I know this because Norton scans outgoing emails.
Anybody?

System.Web is not a class, it's a namespace. Are you sure that it's deprecated? It contains everything that has to do with asp.net, so it doesn't seem likely. Even if it were deprecated it doesn't mean that it's removed, so the code should still work. Why do you think that it doesn't work?
From what you descibe of your problem, it sounds like mail is not sent until the object is collected by the garbage collector. Are you closing and disposing the objects you use properly?

System.Web.Mail and its containing classes have been deprecated in Whidbey. System.Net.Mail is the new location for some much improved e-mail classes.

Yes, that makes much more sense.

Why did they put mail in the web namespace in the first place?

private void SendBill()<br />

MailAddress toAddr = new MailAddress("anybody@hotmail.com");<br />
MailAddress fromAddr = new MailAddress("test@mailserver.net");<br />

message.Subject = "Test Mail";<br />
message.Body = "This is a test.";<br />

This is the code. I changed the server and addresses to post here.

Have you tried disabling Norton's e-mail scanning? I've been using the new mail classes in an app here and it works as soon as I call Send().

I've had the same issue, only way round it i've found is to set the message to null and the smtp instance to null and then call GC.Collect();
MailMessage msg = new MailMessage(adminEmail, adminEmail);
SmtpClient smtp = new SmtpClient();
smtp.Host = "xxx.xxx.xxx.xxx";
smtp.Port = 25;
smtp.Send(msg);
smtp = null;
msg = null;
GC.Collect();

I need to call an unmanaged function that takes, basically, a void pointer to a buffer. I've got the transfer to the unmanaged DLL working by passing a byte [] and letting .NET marshal. However, the buffer may contain different data structures on different calls since it's a kind of generic entry point with the exact function specified in the first field. In C I would do something like this:
char buf[1000];
struct Header {
int cmd;
int flags;
int param;
};
struct Cmd1SpecificData {
double param1ForCommand1;
short param2ForCommand1;
short param3ForCommand1;
// and so on...
};
void foo()
{
Header *header = (Header *)buf;
Cmd1SpecificData = (Cmd1SpecificData *)(header + 1);
header->cmd = 1;
header->flags = 999;
Cmd1SpecificData->param1ForCommand1 = 123.456;
APICALL(buf);
}
APICALL can now look at the first field and figure out what to do.
In C# I don't quite know how to do this. I have a byte [] which is the equivalent of the char buf[] but how do I cast pointers into the byte []? I couldn't find a simple way to copy data from a struct to a byte [] or how to use a MemoryStream to stream the data into the byte [].
My questions:
1) What's the best way of getting the contents of a struct into a byte array? Note that I'll need to get different structures chained together so I might need to put the contents of the structs at specific offsets in the byte array.
2) Is there a fundamentally better way of getting .NET data to an API of this sort? Maybe I should do the marshalling myself and convert everything to a pointer before calling the unmanaged code?
Thanks,
Andrew Queisser
