So what? Shorter doesn't mean better. What if your executable is renamed? Your code won't work.
|

yeah i know, thats why i asked here... so i'll use mutex because it will work when application renamed.
thanks

You are welcome

Your code may be shorter, but it certainly isn't better. The right way to do this is using a mutex which you can guarantee will be unique to your application and doesn't depend on the process name. There are also solutions other than the one presented in the article, but they all work basically the same way. Search for the words "c# single instance application" and you should find a lot more examples.

That's correct, a Mutex is probably the most simple and correct way to ensure a single instance.

Hi All
i am trying to override the PreProcessMessage for the form
and i am using this code
public override bool PreProcessMessage(ref Message msg)
{
switch (msg.Msg)
{
case WM_RBUTTONDOWN: return true;
default: return base.PreProcessMessage(ref msg);
}
}
but this code never been called
i am wondering, why ?
|
|
|
|
|
Do you call the code yourself? If not then i can't see you being able to get the return value from it. Are you sure you don't mean to override WndProc?

I don't really understand the question, but you can find ildasm under (when you have the .NET SDK installed)
Start Menu -> Program Files -> Microsoft .NET Framework SDK (1.1/2.0) -> Tools -> MSIL Disassembler
Alternatively, a better program is .NET Reflector[^]

Do NOT delete your message. It is rude!
IEnumerable and IEnumerator are two interfaces that assist with the iterator patten in .NET applications.
IEnumerable is used on an class that can be iterated over. (-able ending meaning it has the ability to perform an action). The IEnumerator is used on the class that does the work of iterating (-or ending meaning that it performs the action. i.e. It is the actor)

I don't know. I came to the forum too late to see the questions.

Same here. This is why I feel that people shouldn't be allowed to delete their posts once someone replies to them. Now it just leaves a trail of crap all over the forum. Though not as bad as certain Soapboxers spilling SB material into the Lounge.

A GUID is a globally unique identifier. If you generate one it is guaranteed to be unique. You would use one where you want an identifier to be generated regardless of the computer it is being generated from.
An UVID is an Ultra Violet Identifier. It is an identifier that shows up under ultraviolet light. You would place one on your property to make it easier for the police to locate and harder for a theif to sell.
