C# tutorials?

Hi everyone,

I come mainly from a C++ background. However, I am very interesting in learning C#. I am particularly interested in developing my own GUI controls (seems easier to do it than C++). I am also proficient in Java. Can somebody point me to some tutorials or code samples that can help me? Codes for control subclassing or creating controls and registering them with the designer and stuff would be great!

Thanks,

Pankaj

ListBox item length

Nish Nishant31-Jul-02 21:46

Nish Nishant

31-Jul-02 21:46

Say we have a list box and we have items. Now some of the items have long text, so that the entire text won't fit in [means we only see the left most portion that fully fits into the box].

Now we can show tool-tips and solve this issue. But what if I don't wanna show tool tips for those items that have text short enough to fit in the width of the listbox?

How do I determine whether a given string will fully fit into the listbox?

OnMouseHover and OnMouseMove

I have a question about OnMouseHover and OnMouseMove! They seem to be called together Frown | :-(

For example I assume OnMouseHover gets called when the mouse stays at a point for some amt of time. But I find that it is called along with OnMouseMove Frown | :-(

Can someone who has experiences some similar stuff care to explain this to me?

OnMouseHover gets called first and then OnMouseMove gets called. Sorta weird!!! I'd have thought the reverse would have been the natural choice.

My findings:

1. MouseHover only gets called if control has focus.
2. MouseMove gets called regardless.
3. MouseMove gets called when mouse is clicked or control receives focus.
4. MouseHover gets called when mouse hasnt moved for an interval (time???).

Listbox with tooltips?

Does .NET have a listbox with tooltips for individual items? I couldn't find it after a basic search of MSDN?

do an advanced search then. Poke tongue | ;-P

I just looked in the documentation that comes with the SDK, and it doesnt look like it, maybe u can combine the listbox class with the tooptip class or something.

oh, and thanks for the idea, u just gave me another little feature to add to the control im making.

Web Services Implementation Guide

31-Jul-02 18:32

Getting value from stuff you don't own is a compelling
idea. Just think, someone else has created something
that has value, and has made it available to you. You
can now leverage its value in ways that makes all
parties richer. That's the promise of web services.

You need to know about web services. The advent of
standards-based web services marks a new era of
system development. First mainframe, then client-server,
the Web, now web services makes it possible to leverage
every legacy system of the past and do so much more
with your information assets.

Architag Press, a division of Architag International
Corporation, announces the publication of Web Services
Implementation Guide, Volume 1: Getting Started, by
Brian E. Travis and Mae Ozkan.

Sample chapters of the book is available at
http://www.architag.com/press/wsig.

This book will show you what a web service is, and
how you can align your internal systems and external
trading partner interactions to take advantage of this
new concept in system integration.

You will learn about the "Three Steps to Web Services":

* Automate internal systems
* Determine integration points
* Expose integration points as web services

This book is for systems architects, developers,
and I.T. decision makers.

Highlights in this book:

* Written in a light, entertaining style.
* Emphasis on architectural design for web services.
* A tutorial on the state of web services standards.
* Plenty of real-life examples of web service use.
* Tutorials on the key technologies: XML, SOAP,
WSDL and UDDI.
* Code samples of key XML-based web services
technologies and extensions.
* Companion Web site with all code samples and
late-breaking information.

Making a button in C#/.NET the Default for the form

31-Jul-02 13:03

How do I set the IsDefault property to True so that the Button is the default button of the form?

the IsDefault is a protected property, and its inheritted from ButtonBase.. so you can't set it to True

any ideas?

thanks

~Dan

--------------------

If anyone else doesnt know, the property to use is the AcceptButton of the form.
ex: this.AcceptButton = button1;

Re: Making a button in C#/.NET the Default for the form

It's actually a property of the form now - AcceptButton and CancelButton. IsDefault is readonly and returns true if this button is the forms .AcceptButton. These can be set through the form designer or code.

I'm working on a c# application and i'd like to get it launchable from Microsoft Word using a new icon. The problem is I don't know how to do, I've been searching throw articles but they often explain how to launch and control Word from an application and not the contrary.
Could someone explain me how to do such a thing, or at least give me a few steps ?

Thank you.

What does the GCHandle object?

Can everyone explain me the following lines?

<br />
GCHandle handle = GCHandle.Alloc( savedArray, GCHandleType.Pinned );<br />
int scan0 = (int) handle.AddrOfPinnedObject();<br />
scan0 += (h - 1) * stride;<br />
Bitmap b = new Bitmap( w, h, -stride, PixelFormat.Format24bppRgb, (IntPtr) scan0 );<br />
handle.Free();<br />

What does the GCHandle object? Can I use the "fixed" keyword instead, to get the adress of "savedArry"?
