I'm afraid there is no way you can tell the RNG what all the numbers are that have already been picked, so the best you can achieve is avoid repeating the previous number, not all the older ones.
Of course if all the OP wants to avoid is consecutive duplication, then your way would be fine.

Erm, doesn't that just give you a monotonically increasing set of values?

Yes - I'm not saying it's the way I'd do it, just that it is a way.

Yup, but the OP didn't really specify enough to say what he actually wanted, so I gave a generic, if not necessarily useful answer.

How many non-repeating random numbers are you going to want to get ?
What is the range of random numbers - are they integers or real.

Hi
The procedure below takes a name from the Numbe array and places it in a directory path to find an image file to insert into a word document. All the images are numbered 1,2,3,4.... however, when the number gets bigger than 101 then the compiler complains that the file name is invalid, the file does exist so i can't figure out what is invalid about it?
public void CreateFileColumn(ArrayList array, Array Numbe)
{
object missing = System.Reflection.Missing.Value;
object fileName = "normal.dot";
object newTemplate = false;
object docType = 0;
object isVisible = true;
Object oUnit = Word.WdUnits.wdCell;
string FilePath;
wordApp = new Word.ApplicationClass();
wordDoc = wordApp.Documents.Add(ref fileName, ref newTemplate, ref docType, ref isVisible);
wordApp.Visible = true;
wordDoc.Activate();
wordApp.Selection.Tables.Add(wordApp.Selection.Range, 1, 8, ref missing, ref missing);
wordApp.Selection.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphLeft;
wordApp.Selection.Font.Bold = (int)Word.WdConstants.wdToggle;
foreach (string part in Numbe)
{
FilePath = @"C:\Users\Jon\Documents\Nick\Chin Font Files\" + part + ".jpg";
wordApp.Selection.InlineShapes.AddPicture(FilePath , ref missing, ref missing, ref missing);
wordApp.Selection.MoveRight(ref oUnit, ref missing, ref missing);
}
}
Thanks

Hi,
I would need a lot more information to figure this one out.
What is the exact error/exception message? in what line does it occur? which app is giving it: yours or Word?
what is in Numbe?
if you skip the first half of Numbe, does it stop at the same image? if so, there might be a problem with that particular image file? if not, there is some capacity problem, maybe an out-of-memory in Word, a horizontal overflow, ...
three more remarks:
- I would add an overall try-catch construct, and show Exception.ToString()
- is this really C# code? it looks more like PHP, you don't like typed languages do you? what's with all those objects, and why is a string array passed as Array?
- maybe there is an entirely different and more appropriate way to solve the real problem. You seem to be painting chinese text using lots of small images.

Your remarks are all very true, i started programming PHP and very new to C#, about a week ago to be precise. I am trying to make a program that takes a raw text file of numbers and then converts those numbers into Chinese characters, which were hand drawn and scanned in as jpg. So the text file contains something like 1.2.3.4.5. and so forth, so the full stop allows the string to be split and placed into an array. This is then cycled through and the image added to word document which has the same number.
A few reasons for doing it this way is because i want to be able decided how the tables are laid out in word. So i might want them to list in columns and decide how many columns are on each page, the same with rows.
Overall you could say this is trying to automate the process of inserting images into a word document.
The script always works if the number is below 101, as soon as it goes to 102 or higher it causes the error. I have tried changing image names which i know work and the error still is thrown. Therefore, the error is thrown in my code but i don't know whether it could be word causing the problem
the error is on this line:
wordApp.Selection.InlineShapes.AddPicture(FilePath , ref missing, ref missing, ref missing);
saying that FilePath is not a valid file name
I would of thought it would of been an overflow problem if there was already a large number of images, however, if you just type 102 in the raw text file it will cause an error immediately, before it has chance to even add one file to the document.
Numbe is an array which contains all the numbers of the text file, one number in each element of the array.

OK, so no major surprises here.
You can declare string[] Numbe instead of Array; that way the compiler knows it will be strings and string operations are acceptable. Similar things for all your "objects": when you give them a more accurate type declaration, the compiler will be more capable of flagging errors if any, your source code will be more readable, and the running code will probably run a bit faster.
Try images 103, 101 and 102. If 102 is the odd one out, then check the image file itself, chances are it is damaged somehow (try replacing it with a copy of 101! ). [Sorry, this doesn't fit your problem description]
I suggest you print out FilePath before calling AddPicture; chances are you will see a problem with the file name. You might consider showing the code that produces the Numbe array, maybe something is wrong there.
As you are new to a language, I recommend studying a book[^].

I have tried a mixture of numbers and images, which are copies of the same image. It works for a selection like:
1.4.8.120
as soon as you hit 120 it fails, same if that number is any number between 102 up. The files are ok as i have swapped them around many times. if the sequence starts on a high number like 103 then it will fail immediately.
thanks for your help.

hi.
i have web page that contain a button. here is button's code:
<button type="submit" class="btn" style="width: 200; height: 22" onclick="setAction(method,'save');"><br />
<img border="0" src="/evocher/html/image/blt_01.gif" width="13" height="11"<br />
align="absmiddle">Register</button>
i write this code to obtain button:
mshtml.HTMLDocument doc;
HTMLInputElement registerButton = (HTMLInputElement)doc.getElementsByTagName("button");
but it generate runtime error, Invalid TypeCasting.
how can obtain this button?

getElementsByTagName returns a collection of objects. You try to treat it like a single object. I don't know the exact type of the collection, but I would assume that you need to cast it to something like a HTMLCollection

try
Button btn = (button).FindControl("the control Id goes here );
|
|
|
|

Unfortunately not. That only works for windows forms. This uses DOM, which is completely different. Also, you don't call FindControl on (button); that assumes you already have the Button instance. You call it on the Button's parent control

yes you are write i miss typed it it should be this. meaning that find control from this page.
|
|
|
|
|
is there any other solution to get button ?
|
|
|
|
|
I don't know. To be honest, casting getElementsByTagName to the correct collection, and then iterating until you find your button sounds like a fairly efficient approach

I need to refresh my parent page from pop up using __doPostBack in javascript could any body tell me how i tried to googlize it but the information was not that helpful
|
|
|
|

I don't know how to do it using __doPostBack, but I imagine it would look something like this:
window.opener.location.reload();
You would probably get better results by asking this question in the Java forum though.

Hi All,
I am creating windows app, with MVP architecture.I added a textbox and button to the window.xaml, so that my intention is to browse a folder on button click and display the path in the textbox.
If I select MyDocuments in browse click, then the entire path (C:\\Documentsandsettings\....\MyDocuments) should be displayed in the textbox.
I am new to MVP and as of now
1 . window.xaml with textbox and button
2. presenter class (windowpresenter.cs)
3. Interface class (Iwindow.cs) are created .
But, I am unaware of how to link these controls and how to use publish and subscribe these controls.
Please kindly help me in doing this.
Thank You,
Ramm

Hi To all
I`m very new to the programming and got stuck.
So i`ve been trying to write a program using Windows Form which include several different panels on. User can choose between which one is visible.
on each form there are few pictureboxes and my problem is .....
when you swich between them in the runtime it`s not smooth enough  user can see loadning frames of these picture boxes for few miliseconds this is really annoying.
Is there any easy way of loading it in the background and show it after its ready or something ??? I started reading about threads etc but at the moment its quite difficult, i will be gratefull if someone could explain it with an example
Thanks in advance

You could call pictureBox1.SuspendLayout();, load your image into the PictureBox, then call pictureBox1.ResumeLayout(true); to update the layout.
