hi,
I have a PrintPreviewControl on my form, where print preview should be displayed.The problem is, that even when I set the Document Property of this control to a new created document, it doesn't raise any Print event. It always displays "Document does not contain any pages" text.
if (this.DocumentPreview == null)
{
this.DocumentPreview = new PrintDocument();
this.DocumentPreview.PrintPage += new PrintPageEventHandler(DocumentPreview_PrintPage);
this.DocumentPreview.BeginPrint += new PrintEventHandler(DocumentPreview_BeginPrint);
this.DocumentPreview.EndPrint += new PrintEventHandler(DocumentPreview_EndPrint);
this.DocumentPreview.DocumentName = "Generating document";
}
this.printPreviewControl.Document = null;
this.printPreviewControl.Document = this.DocumentPreview;
Do you have any idea why ?

I've solved that,
In case that any1 had same problem, PrintPreviewControl.InvalidatePreview() is the solution.

You are going to want to download the .NET Compact Framework, and the Documentation for it. If you are already a C# .NET developer, you will find that it isn't different at all. Save for that the version of .NET is called Compact. Limited functionality of the framework to save space on a small footprint device.

What did you just say? Not a single bit of that made sense.

Hi,
Is there an innovative way to pick colors randomly??
Any way to pick a color from the
Color object like referencing an index in an array??<br />
<br />
<pre>Color[0];
Color[2];
Color[6];
<br />
Many thanks <br />

Random rand = new Random();<br />
byte[] rgb = new byte[3];<br />
rand.NextBytes( rgb );<br />
Color color = Color.FromArgb(rgb[0], rgb[1], rgb[2]);

Thank you gleat.. Actually, I was managing it that way and wanted to use the pre-defined colors in the Color object.
Thanks for your help!

If you only want to use webcolors you can use the result from a function like this one.
<font>IEnumerable<color> GetColors()
{
foreach (PropertyInfo p in typeof(Color).GetProperties(BindingFlags.Public | BindingFlags.Static))
{
if (p.Name.ToLower() != "transparent")
yield return (Color)p.GetValue(null, null) ;
}
}
</color></font>

You need to explain better. When you press enter, the text is cleared ? How ?
If you don't want to move to a second line, make your control not multiline

Probably Shift+Enter is what you're looking for!

Hi all
I require to store a location path in my web.config file and then use this path in my application by using
mypath = ConfigurationManager.AppSettings["mypath"]
however, this path is being used to load in a dll, like so
[DllImport(mypath+"mydll.dll", EntryPoint="runme", ExactSpelling=true, SetLastError=false, CallingConvention = CallingConvention.Cdecl)]
and because the DllImport is in the head of the class (before any methods) I require to create the path as a constant string, like so
const string mypath= "C:\\mypath\\"
now this works if I don't use the ConfigurationManager to get my path from the web.config and I hard code the path into the class. However, I dont want the path hard coded in.
If I do this though
const string mypath=ConfigurationManager.AppSettings["mypath"]
It complains and says:
Error 7 'myclass.mypath' is of type 'string.' A const of reference type other than string can only be initialized with null
I'm confused by this because I thought ConfigurationManager.AppSettings["mypath"] returned a String, so why cant I just use that?
Does anyone know how to do this?

You should use reflection
1.in runtime Dynamicly write a method
2.Add DllImport Attribute to it and add dll path
3.Invoke the method

Could you give me an example of this please?

It looks like the variable mypath is declared as a const. You are probably declaring this a member variable though. your line of code probably looks like public const string mypath = ConfigurationManager.AppSettings["mypath"]. Try not declaring the variable as a constant, and it should work.

The variable has to be a constant as it is used in
[DllImport(mypath, EntryPoint="runme", ExactSpelling=true, SetLastError=false, CallingConvention = CallingConvention.Cdecl)]
where mypath is used is outside the main constructor so it requires to be a constant
