Hi all,
writing a small app that reads a registry setting and based on the content on that, should either show the form or hide it in the tray bar.
RegistryKey masterKey = Registry.LocalMachine.CreateSubKey("SOFTWARE\\Policies\\OTM");
if (masterKey != null)
{
if (masterKey.GetValue("Serial").ToString().Length == 36)
{
textBox1.Text = masterKey.GetValue("Serial").ToString();
textBox1.Enabled = false;
this.Hide();
}
else
{
textBox1.Enabled = true;
this.StartPosition = FormStartPosition.CenterScreen;
this.WindowState = FormWindowState.Normal;
this.Show();
}
}
unfortunately the window always stays open. Anyone who have a quick tip to what Im missing?
I tried to include this.WindowState = FormWindowState.Minimized;, but that just minimized to app, but didnt hide it in the tray bar. - sorry writing error here. Meant didnt hide the form at all. At best it gets to be minimized in the lower left corner.

Did a small change
RegistryKey masterKey = Registry.LocalMachine.CreateSubKey("SOFTWARE\\Policies\\OTM");
if (masterKey != null)
{
if (masterKey.GetValue("Serial").ToString().Length == 36)
{
textBox1.Text = masterKey.GetValue("Serial").ToString();
textBox1.Enabled = false;
this.WindowState = FormWindowState.Minimized;
this.Hide();
}
else
{
textBox1.Enabled = true;
this.StartPosition = FormStartPosition.CenterScreen;
this.WindowState = FormWindowState.Normal;
this.Show();
}
}
plus included this:
private void Form1_Resize(object sender, EventArgs e)
{
if (WindowState == FormWindowState.Minimized)
{
Hide();
}
}
It is far from beautiful but it works for now...

hello @all,
i use this code to format number values in a textbox:
tbxProzentwert1.DataBindings.Add("Text", bs, "prozentwert1", true, System.Windows.Forms.DataSourceUpdateMode.OnValidation, null, "#0.00#");
I have no other Validation-Formatting in my prog.
So the value will be formatted like
1 -> 1.00
0 -> 0.00
1.4 -> 1.40
thats ok.
But if i write a character or leave the value blank, the focus will stick to the field.
Now i have to put a 0 or any number i it to leave the textbox ...
Is it possible to write a 0 to the value if the value can not be formated ?
Bye jo

Create a function in your class e.g. ShowErrorMsg
pass Active form as parameter and use this syntex
MessageBox.Show(ActiveForm, "Error: " & vbNewLine & vbNewLine & msg, My.Application.Info.ProductName, MessageBoxButtons.OK, MessageBoxIcon.Error)

No, that is useless
1 - Application.Current.MainWindow works anywhere
2 - his issue is that he's in a dll, or he's just not scoped Windows.Forms.

Not in applications without UI's...
The simple answer is that DLL's should never try to make messageboxes unless they are part of the UI. Classes that create errors like that should bubble the error up to a UI or logging component using mechanisms like "throw". That way the application can decide how to alert the user, whether through UI pop-ups, log files, etc.
I've also found it very useful to create an application settings file and store error text information in there, rather than hard code error strings in the application. This allows me to ensure that the grammar, punctuation, spelling, and format of errors are all the same throughout the application. It also makes it very easy to edit particular errors if your test team says that the text is incorrect or vague, you just look in the setting file instead of combing through thousands of lines of code to find every instance.

If this does not work, then you must import the Windows.Forms dll into your dll, or you need using Windows.Forms at the top of your class. Intellisense will show you the namespace you need if you hover the mouse over the end of the statement that has the error. You're really better off throwing an exception tho and letting your presentation layer decide how to deal with it. You can use Application.Current.MainWindow to specific a parent to the messagebox anywhere inside your windows forms app.

Hello friends,
I have a program to connect to url using HttpWebRequest object and download a file from that url.
I have set
httpwebRequest.Proxy = null;
Question: In my application, no setting field available for to define the specific proxy settings - so, does the my programming foresee to use by default the internet explorer proxy setting?
or are there any other ways to bypass the proxy?
Thank You

Hi...
I had a group of computers in LAN. In one of the Systems one PC is server which is having MYSQL databse. I want to connect from another PC which is in LAN. My LAN server name is "Desktop1".
I am using the Connection String as
Constr="Server=Desktop1;User Id=root;Password=sa;";
in c#.net. But it is not connecting the Server which is having MYSQL database. To establish the connection in between the PC's am i need to do anything more.....
Plz help me . I am looking for this from a loooong days...
Thank you...

I believe you need \\Desktop1, to create a network path.

Well, that's a little concerning. If you can't work out a connection string, I'd be worried about your ability to do C# AND SQL.

Heelllllll
I tried evrythng....
but its not connecting...
If u knows y don't u mention the connection string.....

Like I said, it's plain that programming is probably beyond you.
You can have a connection string to a local file, so you need to start your connection string with \\ to show it's a network path. Like I said.
If you can see the machine over the network, then your issue is the connection string, perhaps the user the program runs under, or a combination of the two.

You need to specify the database name as well. Check out ConnectionStrings.com to see all kinds of connection strings.
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

I think we're being flooded by trolls at the moment. I'd put money on this guy being CSS or someone else pretending to be a moron and laughing their head off.

How to place an image in the range (cells[5,1],cell[10,5]) of excel? and how to make it in the center of the range?
thanks!

I hate Excel!
Don't you place the image in the value of Cell(5,1)
I would select the range
Set the vertical and horizontal alignment
Merge the cells
Then add the image
The above is a guess but it seems reasonable.
