Is this a bug in VS or more, likely, a design limitation?
Just take a look at the code. It might be a GUI designer error. Maybe the code will throw more light on the issue

I have a picture in a picturebox and I would like to move it around within the bounds of the form. I like the idea of it changing directions when it hits the outer edge of the form. What is the best way to do this? I have this, but it really isn't doing a whole lot. Thanks in advance.
void MovePic()
{
for(int i = 0; i < this.Width; i++)
{
this.picbox.Top += 1;
this.picbox.Left += 1;
}
}

Actually, real programmers don't need the enter key- they just type in 00001101."

You might want to creat VMove and HMove variables. So it would look like this:
void MovePic()
{
for(int i = 0; i < this.Width; i++)
{
this.picbox.Top += VMove;
this.picbox.Left += HMove;
}
}
Then when it hits an edge, just negate one of the variables.

Hi,
In C or C++,some structures are defined with union. How can
we rewrite these structure in C# so that we can use them as
parameters and pass them into API functions?
And, What's the correspondent type in C# to PVOID type in C?
Thanks in advance!

e.g.
union U
{
int x;
int y;
}
can be written in C# as
[StructLayout(LayoutKind.Explicit)]
class U
{
[FieldOffset(0)]
int x;
[FieldOffset(0)]
int y;
}

There are two equivalents of PVOID in C#
1. void* this is when you are using C# pointers. Something which you should never do.
2. IntPtr this is used to encapsultae unmanaged pointers. Use this in conjunction with Marshal.StructureToPtr, Marshal.AllocCoTaskMem etc. functions. Look up all the functions in Marshal class it would be very helpful.

Hi Rama,
Thank you very much, though, I don't understand all
of them, especially the Marshal part. I will keep
reading some document before asking another question.

i downloaded Rama's screensaver.
i want to ask a few questions:
1,when i test or run the screensaver,what did it do except display moving pictures?in James' screensaver when i press the "h" key,it will display help information!
2,Rama said "RBWRP.dll - This is a Managed C++ application that links with Ravi Bhavnani's WebResourceProvider libary to obtain Code Project Top 10 posters."
you obtain topposters through "webresourceprovider.lib" or "cp's webservices"?
and in RBWRP.dll,how to link with "webresourceprovider.lib"?(maybe stupid question,but i am a beginner,so forgive me  )
thanks in advance!

So it's James screensaver now ? Are you reading this James ? 
Seriously, our screensaver is a bit non-standard in that it has a number of keys. Most screensavers do not AFAIK.
Rama AFAIK does not use the webservice as he had written his own ultra cool web service for harvesting information. That's why he has the top 10 posters, although the web service does not offer that.

My screen saver can display different types of data
1. Latest Articles
2. Latest Lounge Messages
3. Latest Comments and Questions
4. CP Top 10 Posters
In the next version you will also see
5. CP Top 10 posters of the week
6. Quotes By CPians
Items 1,2,3 can be obtained from the CP WebService.
Chris Maunder doesnot provide any means to obtain Item no 4 This is where Ravi Bhavnani's WebResourceProvider comes into picture. If you see Ravi's article he has a demo of obtaining Top 10 posters. I use his code as it is and write a managed wrapper around his class. My screen saver talks to this managed wrapper and obtains the information.
RBWRP.dll is already linked with WebResourceProvider.lib so you don't have to do anything. Look at the solution RBWRP.sln and it would be clear. I am going to write a detailed articles on various aspects of screen saver. I think the screen saver is a good practical example to demonstrate various .NET features.

thanks Rama.
but if i am not bothering you,
can you tell me more about how do RBWRP.dll link with webresourceprovider.lib?
in Ravi Bhavnani's WebResourceProvider demo,
i can see from the project's property that the demo is linked with webresourceprovider.lib!
thanks!

i want to get information about how to build up a web application step by step,
not a sample web application that is very simple,
but a complicated one such as a portal website or e-commerce website.
i mean detailed information about how to establish such websites step by step.
i think many people like me who is not much familiar with asp.net will want to have such informations in order to get a whole impression about vs.net.
so experienced cp's programmers,please give us some cues on how to find such resources.
thanks in advance!

You can look at http://www.asp.net/
There is a really good sample there about IBuySpy portal. Look at that it really good.
|
|
|
|
|
yes,that's a great sample.
but to your experience,are there any resources that's introducing the design of websites from the beginning?
thanks!

I haven't heard much about .NET Windows Forms applications that run inside of a web browser like ActiveX controls or Java Applets. Does anyone have any pointers to books or web sites that cover this in depth? Basically I want to replace our existing application (HTML + ActiveX controls) with C# Windows Forms. I assume there is some way of packaging assemblies in CAB files but I just haven't heard much about this. Thanks!

I am trying to do something similar. I was told by someone at MS that remoting might be a good way to go about it. SOAPSUDS seams to not like forms, so that is out of the question. Unfortunately, you have to send the user an exe and possibly a DLL and make sure that he has the .NET framework. If you can find a better way of doing this, I'm open to suggestions.
