Hello all,
i am a newbie for c# and would like to know if it is correct way to do as below
public unsafe struct test
{
public long lTime;
public fixed char AlphaChar[2];
public fixed char Stamp[8];
public fixed char Stamp1[8];
public fixed char Stamp3[8];
public short tCode;
public short ECode;
public short MsgLength;
public fixed char MSGTEST[4];
}
now i am struck with filling data into this structure.

Hi,
not sure what the problem is. This snippet compiles well:
unsafe {
Test tt=new Test();
tt.Stamp1[1]='a';
}

Hello Luc,
Thanks for the early reply.
Can we set the whole stamp variable to null.

I don't think so, since it is declared fixed, the characters themselves are in the struct now, there is no pointer/reference stored anymore, it is just N consecutive characters.
What is the higher purpose of all this anyway? Are you trying to perform some P/Invoke?
Mimicking a file or network packet content? A hardware register layout?

yes u are right i have sent this packet data on tcp socket and these are server side restrictions.

if the packet definition has N characters for something, then you must provide N characters; you can't transmit "null" can you? You could initialize to all spaces though.
Furthermore, be aware of the fact that .NET characters are Unicode, hence 16-bit, sooner or later you probably need to convert them to/from ASCII.

Hello,
I've embedded a MaskedTextBox in a UserControl and added it to the ToolStrip of a Form via ToolStripControlHost:
private void Form1_Load(object sender, EventArgs e)
{
ToolStrip1.Items.Add(new ToolStripControlHost(new UserControl1()));
}
In the Validating event of the MaskedTextBox in my UserControl the value of the Text is checked and if necessary corrected:
private void maskedTextBox1_Validating(object sender, CancelEventArgs e)
{
if (maskedTextBox1.Text == "0")
{
maskedTextBox1.Text = "1";
maskedTextBox1.SelectAll();
e.Cancel = true;
}
}
The user can give any input in the MaskedTextBox, validation should only occur when "leaving". If the focus "leaves" the MaskedTextBox (by the user clicking anywhere or tabbing), validation is performed.
If validation fails ( in this case Text = "0") a corrected value ("1") is set, no events (e.g. button clicks) occur outside the control and the control's text should be highlighted
After the value was automatically corrected (the user has been shown a warning... not relevant), he can now of course "Leave" without ado.
If the UserControl is added to a Form all the described behaviour occurs.
However as the userControl is put in a ToolStripControlHost I can't get the text of the MaskedTextBox highlighted after the validation of the maskedtextbox (inside the toolstrip) fails.
Any help on this would be sincerely appreciated.

Hi,
I've solved my problem, be it in a manner which could as well be posted under coding horrors:
In the validating event of the maskedTextBox I call on a timer (which was added to the userControl), and let its Tick event set the focus.
private void maskedTextBox1_Validating(object sender, CancelEventArgs e)
{
if (this.maskedTextBox1.Text == "0")
{
timer1.Start();
e.Cancel = true;
}
}
private void timer1_Tick(object sender, EventArgs e)
{
this.maskedTextBox1.Text = "1";
this.maskedTextBox1.Focus();
this.maskedTextBox1.SelectAll();
timer1.Stop();
}
Cheers.

I spent several hours trying to get this working, and to no avail until I stumbled upon your answer.
Whatever dark magic you've applied to this task in order to arrive at using a timer, I take it your journey as a sorcerer is already a colourful one.
Thanks alot sir.

Suppose I want to call a function whenever I'll press Control + N together.
Now I know I need to catch the keyPress event. But how can I catch two key in one event..?
Thanking In Advance

You need to use either KeyDown or KeyUp events.
if (e.KeyData == Keys.N && e.Modifiers == Keys.Control)
{
}

Hello,
I have a web site with files and direcotires (with files and other directories and files.....in each).
I need to find a particular file in this site (i will provide the main site and it will search recursively inside it and inside the folder to find the file i need). How can i do it?
|
|
|
|
|
First of all this should be in ASP.Net forum.
Use the DirectoryInfo and FileInfo classes to perform the search.

ok,
And it can search in web sites too?
BTW- i want to do it in C# windows application and not in ASP.NET
|
|
|
|
|
Well, that can do the search everywhere provided you have the read access in that website.

DirectoryInfo myDir = new DirectoryInfo("http://www.yahoo.com");
?
Or how?

Hi my friends;
I have a different problem. I have a main form that is MDI parent of other forms. I use speech recognition, and I started it as a thread in my main form. It works fine while opening child forms or closing them. But problem begins here. For example I have an active MDI child that have a method or button click event. How can I call the method of my active form from it's MDI parent. I want to do this because I use speech recognition, I want to guide program with my voice commands. Like following I want call DoJob method.
Form frm = this.ActiveMdiChild;
frm.DoJob();
Thank you.

Not sure which exactly is your problem, but you can do it this way:
1) In the child form, the DoJob() method must be either public or internal (in order to enable access from the parent form).
2) In your parent form you can do something like:
ChildForm cf = (ChildForm)this.ActiveMdiChild;
cf.DoJob();
where ChildForm is your child form's class name.
2+2=5 for very large amounts of 2
(always loved that one hehe!)
