I'm raising an event in a component, using ISynchronizeInv oke.Invoke, and my
event args object contains a string as one of its members. If the string is
longer than 63 bytes, the Invoke call pulls an unhandled exception in
System.Windows. Forms.dll, to the effect that the string length must be less
than 64. If I trim the string to 31 characters (62 bytes) everything's fine
and the event goes as intended. But if the string length is 32 or greater,
the unhandled exception gets thrown.
Is there some kind of limit in the marshaling that's going on with Invoke?
Or what? I've looked on groups.google.c om but haven't yet stumbled on search
terms that produce any discussion of this. Any ideas?
Thanks,

Sounds like you are trying to set the text of a NotifyIcon which can only have
a small number of characters. This isn't an invoke problem, but rather a
problem
with the underlying API you are calling through invoke.

Is there a maximum length for Javascript program lines?
What about strings? Is there a limit on string length?
I found some references that said the maximum string length was 256
characters, but I have a program that created a string of over 25,000
characters (the browser was Konqueror).
Are there limits on these lengths? If I require a newer browser for the
program I'm writing, would that change the situation?

Hi,
I'm new to using std classes, but I was wondering how I could do the
following efficiently with the string class:
Say I had a string with delimited values such as:
"field1,field2,field3,field4"
and I wanted to to place those 4 fields into different variables I would do
something like:

Hello,
I was wondering if there is a method that exists to replace multi-spaces
within a string with single-space.
eg:
"12 3 4 56" --> "12 3 4 56"
I think this could be done by looking at each char within a loop and copying
the char to a stringBuilder instance
if current and previous char are not spaces...

is when the number of string concatunation is more then N ( N varies between

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

For most users, this new feature is actually very convenient. If you want to control the update process,...
