.NET CLR cannot reliably catch stack overflow exceptions.
StackOverflow exceptions will sometimes shoot right past all your catch blocks and leave your process in an invalid state.
This happens because CLR does not throw the exception until it is truly out of stack, so there is no stack left to handle the exception.   This has caused me great discomfort.
Java does not have this defect becuase they had the good sense to throw the exception before the thread is truly out of stack.
This is an intermittent bug that is difficult to duplicate. Here is a self-recursing function that eventually throws a stack overflow. But depending on what other code is in the function, it may or may not be caught in VB.net. I could not duplicate the behavior in C# in a simple sample, but have experienced it first hand in a real C# app:
http://www.standards.com/VBNET/TryCatch.html
Hopefully if enough noise/publicity is made, MS will fix this sooner rather than later.

HAHAHA, it was in fact a flaw that it was being caught in some cases in .NET 1.1. In .NET 2 its totally uncatchable. There is something very wrong with your code if u hit a stack overflow. Sometimes however, you might just have a lazy recursive method (like probing a double linked list without tail calls). Those you should be aware of in the 1st place. From my experience the runtime stack allows up to around 16K nested stacks, by default. Add some counters like:
try
{
count++;
if (count > 15000)
return null;
return foo;
}
finally
{
count--;
}

hi,
I have two tables
Table1:Cust_Master CustID (identity type) CustName
Table2: Customer details
CustID
CustName
CustAddress
Cust phone
....
The tables are designed as: if the customer details has to be added it has to be first added to the Cust_master then get the Cust_Id (which gives autogenerated key) and then add it to Customer details table.
Now:
I want to show a editable datagird in WinForms where I give the user an option to add/modify and delete the customer details.
Can any give me the idea of how I can accomplish this.
Thanks

Hi i'm creating add-in in C# in order to create a list of the Project references for the entire solution. From my understanding, when you import a COM object ( ocx or dll) it creates a wrapper around the COM object and it names the wrapper Interop.<filename>.dll regardless if its a ocx or dll. I am using the DTE and VSproject objects to access the references collection for each project in the solution within my add-in . My problem is, the reference collection is pointing to the wrapper local copies. I wish to display the absolute original path of the reference. Basically instead of getting the wrapper Interop.filename.dll i want it to have the original filename.ocx or filename.dll

I have a text box to get info off the user. It should be an int but i cant be sure so i must validate it first. How do I tell if a string is an int? I know i could do Convert.toInt.... and put it in a try catch but is there another way? Thanks in advance

try int.TryParse()[^]
Look up the overloads too, because it intially expects an int with no formatting whatsoever, but using system.globalization.numberstyle.* you can have it automaticlly handle commas, currency symbols, etc.

You could use a regular expression to test the string to see that all characters are numeric.
Somthing like:
private static Regex _isNumber = new Regex(@"^\d+$");
public static bool IsInteger(string theValue)
{
Match m = _isNumber.Match(theValue);
return m.Success;
}
*not tested

You can also try to capture the KeyPress event on the text box and check the user input.
void TextBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(!Char.IsDigit(e.KeyChar) && e.KeyChar != (char)8)
{
e.Handled = true;
}
else
{
e.Handled = false;
}
}
(char) 8 is the backspace key...so the user can actually delete the entry as well !

I have a big Problem with an Word Export from C#. I want to create a Table where I write two words in a Cell. I want to have the first one Bold = 1 and the second one Bold = 0, but I can´t seperate the two words. When I write Cell(1,1).Range.Bold = 1 then the whole Cell is Bold 1. Is there a posibility to write two different Words in one Cell with different Bold.
Cell like:
Word1
Word2

Hi.
I need a sample code for running two threads simultaniously that each of threads fill own progress bar?
Best wishes

There are two discussions of threading within one page of this post, a tutorial in MSDN on threading, a help topic on your own machine if you installed the help files, etc. etc. Are you getting a feel for what you should do FIRST before asking questions on the forum? Once you have the basics, then ask questions about the parts you can't get working.

I use visual studio .net 2003

I can't see it.
How to get Microsoft.Win32??^^;;
System.Environment too...^^;;
Nothing!! But gonzo!!

It is not in a separate assembly. Although named with a different namespace these classes (Registry etc) is located in mscorlib (this one is normally always referenced - its the base for every .Net app). Putting a using Microsoft.Win32 at the top of your class(es) should just be fine.

I didn't know.
Everthing is very good!!^^b

Hi.
How can I manage the close button of a form ?
I want when user clicks the close button(in title Bar of a form), I determine what happenning(instead of closing form).
Best wishes

|
|
|
Catch the Closing event or override OnClosing within the form. It provides CancelEventArgs which you can use to cancel the closing (and instead do something else).
