Thank you. I got the answer.it should be something like this
RegistryKey objKey = Registry.CurrentUser.OpenSubKey(@"Software\Microsoft\Installer\Assemblies");
string regfilepath = "";
if (objKey != null)
{
foreach (string Keyname in objKey.GetSubKeyNames())
{
if (Keyname.IndexOf("ApplicationName.exe") > 0)
{
regfilepath = Keyname;
break;
}
}
}

I'm working on learning C# using VS2008, and have started a project for various mathematical functions. Everything was working fine, until I tried to separate the file into individual classes. In order to do this, I created a new class (.cs file) for the calculations. Within these classes I needed to reference text boxes found in the Window1() class, so I added this to the Calculations() class:
Window1 w = new Window1();
along with it's twin in the Window1() class:
Calculations c = new Calculations();
Now every time I try to compile and run the program, it returns a System.StackOverflowException error and crashes immediately.
From what I've been able to find courtesy of google, this is because of a redundant loop, but I don't understand where this would be. Debugging the code points to the first class definition above, but as I understand it all that does is make the Calculator() class able to reference the Window1() class.
Thanks for your help!

Where did you add these lines, and why? In the constructor? If yes, then it's no surprise your app crashes - your Calculations instance creates a Window, which creates a Calculations instance, and so on, and then, Wham!
You have to use a better way to pass your form data to Calculations. In fact, creating a new instance of Window1 in Calculations does just that - creates a new instance; you will not be able to access your form's data from that instance.

Okay, I had a whole longer question in here, but I answered it myself (well, I figured it out and once I did, your explanation made sense...I was placing one new Window1() statement in the Calculations class and vide versa rather than individual ones in each method of the given class).
Thanks for the help

Actually to clarify (in case anyone searches this later with the same question, I ended up using ref to pass get the result I needed. Now everything works beautifully.

I hate to say it, but the quality of this forum drops to zero every day at around this time. What country starts to provide a lot of posts at this time ?
You're an idiot. Your question makes no sense, it can't be answered. What do you mean by 'system level' ? Why is google broken where you live ? Why don't you own any books ? What are you asking for, and why ?

How can I get a domain name from a remote address either IP or host name?
I could get the host name by
Dns.GetHostEntry(IP/hostname)
but what about domain name?
Thanks,

Hi all
I hope help me
I want change ipaddress in pocketpc2003, that conneted the activesync
I find registry HKLM\Comm\USB Cable:\Parms\TcpIp, so i modify different ipaddress
but after softreset, dont mofied that ipaddress.. 192.168.55.101
how to change ipaddress 210.xxx.xxx.xxx?
Please reply for me

You want to do this with C# ? I don't think you can do it at all. The ip address is assigned by whatever network you connect to. 192.168.xx.xx means you're on a local network, I believe, and either way, you will get an available address from the specifically available range, you can't just make one up.

That's not a question, it's a statement.
I suggest you go and talk to your teacher. We're not here to do your homework, and if we did it, it would only set you up to fail the next. only slightly less trivial, task that your teacher will give you.
We also prefer people who are not rude, or stupid. You're asking us for help, try to be polite, and try to follow the forum guidelines.

Really not at all sure what you're getting at here.
I think, perhaps, you're talking rubbish. How can a node on a graph be the name of a variable? Doesn't make any sense.

People in fourth grade, are 10 years old. Perhaps it works differently where you are ?
your question, however, makes no sense. Are you doing a programming class ? You'd do better to ask your teacher. He feels he's given you all you need to do the task, and it's valuable for him to know he's failed in this regard, as well as knowing what it is you want to do.

Hi,
I have a Form called Form1 that contain a DataGridView. This is an MDI N-Tier Application. In the Form2 Form_Load event I have a method that executes when the form loads.
How can I NOT execute this event when I click on the "New" menu option?
I tried the following but it does not work:
Form2 frm2 = new Form();
if(frm2.Menustrip Functionality)
{
Method()
}
else
{
}
Illegal Operation

if its in Load event then no you cant but you can make that method public and call it when require.

Can you maybe show me a quick example? I am sorry but I do not know how to call it? It's purpose is to set a property I need to browse records.

its same as you calling it from Load event.
frm2.ThatMethod();

in my app the cldfrm's MDIparent=this in the main form.when i try to show the chldfrm by using showdialog() i get this exception.
Form that is not a top-level form cannot be displayed as a modal dialog box. Remove the form from any parent form before calling showDialog.
what i want is to stop accessing the main form while the child form is displaying
|
|
|
|
|
Instead of using MDIParent = this; try using MDIParent = ParentForm.ActiveForm;
Illegal Operation
|
|
|
|
|
thanx for your replpy , but when i try MdiParent = ParentForm.ActiveForm; the ActiveForm wasn't in the list but i tried MdiParent = ParentForm and i works .
|
|
|
|
|
now again i get another problem, once i set the things like that the chldfrm is not in the MDI scope , means onec u maximize the form it goes beyound the main form frame. means the MDI concept is not working. any suggestions to over come this
|
|
|
|
|
Dude you cannot use ShowDialog if you are keeping it as a child form .. .
just go for show();
E.g.
Form2 frm = new Form();
frm.MdiParentForm = this;
frm.Show();
|
|
|
|

I wrote an article about this here[^]. The solution is to restrict the movement of a dialog form rather than trying to make a dialog form a child which isn't possible.
