Methinks you'll need to SetClipboardData() with null data (i.e. just register the clipboard format) and then handle the WM_RENDERFORMAT and WM_RENDERALLFORMATS messages.

I am loading up DataSets which use about 2GB of memory. My memory usage shows aproximately .5GB at start, then as it allocates space for the DataSets I show 2 GB being uses, I then get an error message saying I am out of memory yet I still have 1.5GB left. I have eliminated the possibility that the method is not working correctly.
Does anyone have any ideas on how to proceed or what the problem may be.

Why are you trying to put such a massive amount of data into memory?

Is this a 32 bit or 64 bit application? A 32 bit application can't address more than 2 GB of memory.

Hi, all.
If anyone knows of any articles or web sites that go into detail of a 'high score system' or internet usage (like a simple multiplayer game where you can chat) I'd be greatly appreciative. Also, if anyone could tell me how to publish a program... Step 1) Zip up contents - what are all the contents? Step 2) eMail content???
Thanks!

Hich scores can be stored whereever you like, the registry, XML, a flat file. It's up to you. Any internet based stuff is going to revolve around a central server that at a minimum acts as a hub to allow players to find each other, even if traffic after that goes direct between the players.
To deploy a program, you're better off creating an installer, which also means it can enforce the need for the .NET framework.

hi
i want, search in network for online computers by this code :
System.Diagnostics.Process pr = new System.Diagnostics.Process();<br />
System.Diagnostics.ProcessStartInfo pstart = new System.Diagnostics.ProcessStartInfo("cmd.exe");<br />
pstart.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;<br />
pstart.UseShellExecute = false;<br />
pstart.RedirectStandardOutput = true;<br />
pstart.RedirectStandardInput = true;<br />
pr.StartInfo = pstart;<br />
pr.Start();<br />
System.IO.StreamReader reader = pr.StandardOutput;<br />
System.IO.StreamWriter writer = pr.StandardInput;<br />
writer.WriteLine("net view");<br />
writer.Close();<br />
StringBuilder sb = new StringBuilder();<br />
<br />
while (!reader.EndOfStream)<br />
{<br />
string line = reader.ReadLine();<br />
if (line.StartsWith("\\"))<br />
{<br />
line = line.Replace("\\", "");<br />
sb.AppendLine(line.TrimEnd(null));<br />
}<br />
}<br />
this.textBox1.Text = sb.ToString(); <br />
pr.WaitForExit();<br />
pr.Close();
this code work correctly, but my problem is that when i set UseShellExecute property to false, this line of code :
pstart.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
does not work and cmd.exe was shown, how to solve this problem and prevent from show cmd.exe ?
thanks

AFAIK you can't. There basically are two kinds of apps:
- Windows apps, they can create and show a form, but they can not perform input/output in a
console window (such as "Command Prompt").
- console apps, they can create and show a form, and perform console input/output; when launched
inside a console (as a DOS command) they use that console; when launched outside, they create
a new console (which you can hide afterwards, but it WILL initially show no matter what).
cmd.exe is clearly a console app.

hi Luc Pattyn
in win app, when u start cmd.exe from your app, u can set input/output to your app(did u test my code ?), but my problem is not that, my problem is that how to prevent to display command prompt when i run cmd.exe with useSellExecute set to flase.
thanks

Try setting CreateNoWindow property to true.

Greetings,
Mostly I use enumerations to specify a list of constants that are connected.
However, recently I needed to create a code that does the following:
Paint a line with a specific color that is set by the value of the bits in a variable.
The bits values are arranged in enumeration:
enum bits
{
Switch1 = 1,
Switch2 = 2,
Switch3 = 4,
switch4 = 8,
}
What is the best way to assign a color to each switch?
I thought of two ways:
---------------------------------------------
creating a dictionary and set its values in runtime:
Dictionary<bits, color=""> Bits_Colors = new Dictionary<bits, color="">;<br />
<br />
Bits_Colors.Add(switch1, Color.Red);<br />
Bits_Colors.Add(switch2, Color.Ivory);<br />
..</bits,></bits,>
But this solution because the dictionary is not constant and readonly would not help here.
-------------------------------------------------
Creating another enumeration for the colors and using thier names as params to Color.
<br />
enum BitsColors<br />
{<br />
Red = 1,<br />
Ivory = 2.<br />
Blue = 4,<br />
Green = 8<br />
}<br />
<br />
string name = Enum.GetNames(bits, (int) switch2 );
Color c = Color.MakeByName(name);
-----------------------------------------------------------
I wrote the code from my memory so it might be a little not working.
Sincerely yours
Y.R.

How about an array ? A constant array of colors, and you reference it by index, using the value that is the combination of your bit values.

Thanks for your reply.
I thought of that but there are two problems:
First, I don't think there is an easy way to make array a contant (except for basic types arrays).
Second, my bits values are not 1, 2, 3, 4... (which would fit to an array).
They are 1, 2, 4, 8, ... (Which requires some logic to be implemented in an array).
I thought of constant dictionary but I don't think there is a way to make the dictionary constant or readonly.
Sincerely yours
Y.R.

You could use attributes, but the code can be verbose and (perhaps) inefficient.
I'd stick with the readonly static Dictionary idea; wrap it in something so the code that uses it can't change it.
|
|
|
|
|
I thought that this is the only way.
It strange that such a powerful language don't have this simple features.
Thanks for your help.
Sincerely yours
Y.R.

Microsoft tends to do the hard stuff and leave the easy stuff to you. (Which is better than the other way around.)

How to load HTML file using XmlDocument class
I try to do
System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
doc.Load(path);
but html document not considered by doc.Load method like regullar xml document since what have some unclosed tags such as an other unwell formated things(<link)>Can i actually load this html file by using System.Xml.XmlDocument() for purpose transform this HTML file into an XML file by using XSLT.
THANK

As you have found, not all HTML documents are XHTML. Therefore, a DOM class will not load them. An XSLT can generate non XML documents, but it cannot work with documents that are not XML to start with, you need a different solution.

HTML doesn't conform to XML standards. However XHTML does. The following text comes from the Wikipedia article for XHTML:
Whereas HTML is an application of Standard Generalized Markup Language (SGML), a very flexible markup language, XHTML is an application of XML, a more restrictive subset of SGML.
A solution to your problem would be to convert your HTML code to XHTML which can be understood by the XML parser. I'm not aware of a component that can do this. However this article[^] explains the processes involved.

Personally, I do use SgmlReader[^].
In addition you could use my Zeta Html Tidy[^] library.
I am using both, SgmlReader andy Zeta Html Tidy, together in some projects.
