I have a print preview dialog that allways previsualates what is due to be printed. The previsualization work's fine, but the printing fails.
I think that this may occur because at the printing algortihm the document.Print(); is called again.
Is there any posibility to print directly the data previsualizated (into the control) without beeing necesary to recalculate (generate) it (through the document?

Hi
You can do this by deriving a class from PrintController.
When the dialog "prints" to generate the preview, save the metafiles produced. Then when the dialog "prints" to the printer, just return the saved images.

Nicholas wrote an article on how to get the meta files of the preview and store them as images. You can find it here[^]. You will have to redirect the meta files into a new print job.
Note that you nevertheless need another PrintDocument.Print cycle but you won't have to regenerate the output.

Thanks, exactly what I had to read before implementing an dirty method for obtaining the PageInfo from the preview control (reflection way). Didn't see the GetPreviewPageInfo() procedure.

If this is the case, (print preview is fine, print is not) then chances are you have some variables not reset somewhere, or set to the wrong value. I would suggest trying to figure out exactly what the problem is before "masking" the problem with another solution.

The problem was simple, I was doing a heavy print job, each page lasted for 1 sec to generate and there wore at least 10 pages. The request from the client was to be able to preview what is due to be printed. The solution I approched was this : into the print document I did a lot of heavy work ( the preview looked ok ) and in an inharited printPreviewDialog, on a print request, using reflection, I printed what was in the cache of the dialog (with out calling the document.Print() method again.
I think that the dialog I designed can be usefull, so I intend to create an article based on it, but not now, currently I am time pressed.
PS: thank you for your answer.

Hi all,
I would like to get a list of Windows Desktop Shortcut's so I can build a list (with associated icons). How can I do this and display the icon and trigger the app when the link is selected?
Thanks in advance.

Probably you should get list of *.lnk files in desktop directory:
DirectoryInfo di = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.Desktop));
FileInfo[] fi = di.GetFiles("*.lnk");
Keep in mind, that system links (My computer, My Documents) has no lnk file.
Then, for each lnk file you should call shell function CreateShortcut:
IWshRuntimeLibrary.WshShellClass ws = new IWshRuntimeLibrary.WshShellClass();
IWshRuntimeLibrary.IWshShortcut sc;
for (int i = 0; i < fi.Length; i++) {
sc = (IWshRuntimeLibrary.IWshShortcut)ws.CreateShortcut(fi[i].FullName);
}
Don't forget to add reference to %system32%\wshom.ocx.
sc object will hold all information about link:
sc.TargetPath - link target
sc.Arguments - launch arguments
sc.IconLocation - string, that could be used to get icon.
These two articles could be helpful for icon extraction:
Win32
.NET
Hope it helps.

1) You don't need to select it to add nodes
2) treeView.Nodes[index].Nodes.Add(new TreeViewNode)

Hey
Basically I have a project with several forms which each need to access teh same instance of the Prog class. Where should I define this instance to make it visible to all forms?
Cheers

Hi
I create a Glob class ( Global is a keyword ), then create public static properties for global variables.
internal class Glob
{
private Glob() { }
private static Prog _Prog = null;
public static Prog Prog { get { return _Prog; } set { _Prog = value; } }
}
Some people say that global variables are a bad thing, but like any construct, they are sometimes useful

hey guys I have two questions ( sorry if they are stupid ones ...)
1- I have two forms in one i declare a variable
public int number;
Then i assign a number to it and i want to use it in my second forms
firstform ff = new firstform();<br />
messagebox.show(ff.number.tostring());
I don't get the correct number ?!
2- I have a Combo Box, the list comes from a table called StateDB
State_cb.DataSource = StateDS.Tables["StateDB"];<br />
State_cb.DisplayMember = "StateName";
and it works but i also want to bind it with another table meaning that in my second table called University i have a list of people that are from diffrent universities when my form is loaded I want to have the correct state for that person already selected but it doeasn't work out that way.
State_cb.DataBindings.Add("SelectedItem", myDS.Tables["UniversityDB"], "UniState", true);
Is it possible to do so ??!!
sorry it got so long

What do you mean by this?
I'm taking a guess in the dark here but:
You've already got a form which contains a number and you want to get that number from it. The statement:
mrkeivan wrote: firstform ff = new firstform();
will create a new instance of the class and have a "new copy" of the variable. If you want to access the other instance of the form then you'll have to create a property or field that's accesible to both routines so that you are getting it from the correct instance.

ok let me light you up , I have to forms, in form one I have a variable called Number
public int User;
in the process this variable recieves a number.
In the second form I need this number for another process, but all i get is either Zero or nothing.
how about the second problem about the combo box can you help me out with that one too ?
Thanx alot
Mr.K

I still think that it's because you're creating two instances of the form, i.e. you're retrieving the number from a new copy of the form. (Based on your new firstform statment).
mrkeivan wrote: Zero or nothing.
Eh? For an int zero is nothing
mrkeivan wrote: how about the second problem about the combo box can you help me out with that one too ?
I don't do that much databinding so can't think of the top of my head and don't have the time to mess around trying things out. Sorry.

I also think the same, that the problem goes back to creating two instances of the form, so how can i do that, is there any way i can call that form with out creating an instant of it ?
I was thinking about creating a class to hold the data but again i gotta creat a new instant of that clas:(s !?!

Why didn't you say you were creating two instance of the form, it's a guarantee that this is the problem 
mrkeivan wrote: is there any way i can call that form with out creating an instant of it
Yes, multiple ways, the easiest would be in the form which creates the secondary form, create a public field / property which is accessible to all the method ("processes") which you require. They can then reference the form through them.
