Thank you so much. It worked by directly running the .exe file. Also i created a simple DLL which implements a sum function. When i implement it in C#, it says it can not load the dll. I copied the DLL to the current folder. I do not know why it is not loading the DLL. Do you know why?
Thanks again

I'm sorry, I don't - if the usual rules of dll's is being followed it would need to be in the release/debug folder or in the System directory, but this goes beyond my experience with P/Invoke.

The problem was with my 64 bit windows (Vista). I have a couple of issue with it and this is one of them. The code runs fine on another machine (32 bit vista). Thanks for the help though.

If you wrote it in C++, the name of the function as seen by other tools will have been 'decorated' (some people say 'mangled') with extra characters indicating the types of the parameters. This is to support overloading, that is, multiple functions with the same name.
To suppress name mangling for a function, put extern "C" before the function declaration.

Nope, you'll have to be more specific for us to help you. Could be a coding issue, networking issue, any kind of issue.
I doubt it. If it isn't intuitive then we need to fix it. - Chris Maunder

Your Question Does not make any sence. Please be specific.

I Think you want to mean , you want some update operation and you want you progress bar moving !!! isnt It ?
ellllllllie wrote: any idea
If yes, Try to use BackgroundWorker Components in C# . because Progress bar run on Foreground thread and with low priority where as your background jub run with high priority. Thats why, you are getting your progress bar Stop Increasing, because your UI is not refreshing.. So Try to understand Background worker and work with it.

Im trying to pass a Class I have created to a button and am having some trouble finding where to overload the call function.
Here is the buttons code.
private void btnCalcLife_Click(PumpTest pTest, EventArgs e)
{
intgrav(pTest);
lblLife.Enabled = true;
lblLife.Text = lblLife.Text + pTest.tlife + " Hours";
}
The error is taking place in my designer window
this.btnCalcLife.Click += new System.EventHandler(this.btnCalcLife_Click);
|
|
|
|

The event handler of your button click must take object as a first argument. That's why you are getting error.

I changed it to several different overloads, but still getting an error. Here is what it is now
private void btnCalcLife_Click(object sender, PumpTest pTest, EventArgs e)<br />
{<br />
intgrav(pTest);<br />
lblLife.Enabled = true;<br />
lblLife.Text = lblLife.Text + pTest.tlife + " Hours";<br />
}
I think I need to change this statement but dont know what to change it too
this.btnCalcLife.Click += new System.EventHandler(this.btnCalcLife_Click);

Why don't you have a look at documentation of button click event? You can't add additional parameter to the event handler.

As Giorgi said, you cannot change the parameters of the event handlers. For the Click event, you get the first object sender parameter, which is always a reference to the Button sending the event (you can cast it), and EventArgs e which is useless. Other events pass arguments (eg. location where mouse was clicked) in an EventArgs-derived second parameter.
If you create your own event, you should derive from EventArgs to create your own class for passing parameters to the event handler. But you can only do this for events you define, not for system-defined events.

Yea thanks for the help, I found an article online about setting up a ridiculous way to send something to a button through a wierd method but found it easier to just set up another Public instance of the class and set it equal to the class passed by the parent form.

No, nobody knows anything about it, and if they did they certainly would not create a Wikipedia page on that subject, and if they did you certainly would not be able to find it by searching with google.[^]
Good luck, you're going to need it.

The unfortunately reality is that a truly anonymous peer-peer application used to be possible through the use of Broadcast packets however the potential abuse is too high.
Read up on Tor and Onion routers for a good look at anon. Peer to Peer.

Does your custom control publish a public ImageList property?
