Hi I am trying to build a bluetooth application. I am trying to connect my laptop to my phone. This is the code i am using. I dont know why i keep getting this winsock error 10014. I looked into MSDN which says
"Bad address.
The system detected an invalid pointer address in attempting to use a pointer argument of a call. This error occurs if an application passes an invalid pointer value, or if the length of the buffer is too small. For instance, if the length of an argument, which is a sockaddr structure, is smaller than the sizeof(sockaddr)."
I am not sure how to check the buffer and how can i find out whats wrong. Please help me i am stuck!!!

Ask this question in the Visual C++ forum. I don't see anything in here that's .NET related.

You should ask in the C++ forum like Dave said. There's nothing to do with .NET in your problem. Now, can you tell where the error is occuring, rather than just dumping the whole code. Makes it tough to isolate the problem.

Hi,
Is there any provision in dotnet architecture whereby if I simply create one CS file,
no matter what the application does (let any task execute), the control always ends at this CS file?
Thanks,
NetQuestions

Nope. Your "task" code would have to call this code directly if you wanted it to execute.
Or, if your code isn't dependant on any user interface elements at all, you could put it after the Application.Run(form) that starts your app.

Hi,
Could anybody help me in identifyieng free and opensource tool for source code versioning and bugtracking which can be seemlessly intigrated in Visual Studio 2008.
thanks in advance

Thankyou very much for the reply....
But please also tell me about the free bug tracking tool for dotnet applications.

Hi,
In an existing application, without touching the CS File for MDI or it's designer CS File,
how can I at run time, add a button to the MDI?
I am looking at writing a standalone CS file which should do the magic.
Thanks,
NetQuestions

Create the button:
Button myButton = new Button() Give it some text:
myButton.Text = "Press me!"; Assign an event handler:
myButton.Click += new EventHandler(myButton_Click); and add it to the form:
myForm.Controls.Add(myButton); Magic

Simon,
Suppose I have a form which has 5 buttons. On click of all the five buttons the MDI opens (all different tasks).
The code that you provided, if i write in a stand alone CS file, how do I get it implemented?
How is my CS file method invoked? I DO NOT WANT TO CALL IT EXPLICITLY ... that is a requirement!
|
|
|
|

This code would go in your form code, not normally a seperate CS file. The buttons show up on your form and call this code when the buttons are clicked.
NetQuestions wrote: I DO NOT WANT TO CALL IT EXPLICITLY ... that is a requirement!
This doesn't mean anything. I think you need to describe what your requirement is and why you have it as a requirement.

NetQuestions wrote: I DO NOT WANT TO CALL IT EXPLICITLY
Unfortunately, that is kind of how programming works. You can't just write a method and expect it to magically get called, you have to call it from somewhere.
How do you want it to get triggered?
You need to describe your requirement in more detail. What is it you are actually trying to do? I've shown you how to create and add a button to a form at runtime. All you have to do is decide how and when you want this code to be run.

Ohh.. Clever. You should write an article on that. Actually, just think about it, and I'll read your mind.

Simon,
let us say that my application is run, can i add any plug in or can I run a batch for the same?
|

Hi,
Let me make a wild guess. When you said "standalone CS file", you actually meant a completely separate application to the one that gets the new button.
Now you are throwing in other terms, plugin and batch. This all sounds a bit random to me and I think that if you can say precisely what it is that you want your programme to do then someone may be able to give you an answer.
Alan.
