In that case webservice seems to be a better option to me.

when it comes to reliability,integrity and performance, is it okay?

Depends - what kind of interaction do you want with your VB app?
I would not recommend Windows services - it's a Bad Thing to have a Windows service interact with the user desktop, and I believe this is not even possible on Wista/7.

I would like suggestions(or modifications) on ways to architect the following:
Goal is to create a set of sql server reports 2008 that has a table of contents and
is exported to word 2003 or word 2007.
1. I am going to have each sql server report 2008 as separate RDL files.
2. I am going to tie all the repoirts together in a C#.NET application
by Building Reports from the Object Collection using ReportViewer.
3. I then need to create a table of contents that exports to word. To accomplish this task I am thinking of a. either using jquery so that I can add auto TOC generation, and/or b. write a .net embedded custom application on each report that will obtain the report name and page number from the report footer. The data will then written to a 'table of contents' sql server database that will be used to help generate the table of contents.
Let me know what your thoughts are and/or any modifications you may have.,
Thanks!

I am working on a project that takes 30 images from file, stuffs them in an array and displays them sequentially in a random order. There is a 30 second delay between each image, like a slide show, and no image can be displayed more than once. I got everthing down except for the dont display the same image twice and the end the sequence once every image was displayed. Here is my code.
using System;
using System.Drawing;
using System.Windows.Forms;
namespace Random_Image_Generator
{
public partial class mainWindow : Form
{
int timeKeeper;
Bitmap[] images = new Bitmap[30];
public mainWindow()
{
InitializeComponent();
timer1.Interval = 1000;
images[0] = new Bitmap(Bitmap.FromFile("0.bmp"));
images[1] = new Bitmap(Bitmap.FromFile("1.bmp"));
images[2] = new Bitmap(Bitmap.FromFile("2.bmp"));
images[3] = new Bitmap(Bitmap.FromFile("3.bmp"));
images[4] = new Bitmap(Bitmap.FromFile("4.bmp"));
images[5] = new Bitmap(Bitmap.FromFile("5.bmp"));
images[6] = new Bitmap(Bitmap.FromFile("6.bmp"));
images[7] = new Bitmap(Bitmap.FromFile("7.bmp"));
images[8] = new Bitmap(Bitmap.FromFile("8.bmp"));
images[9] = new Bitmap(Bitmap.FromFile("9.bmp"));
images[10] = new Bitmap(Bitmap.FromFile("10.bmp"));
images[11] = new Bitmap(Bitmap.FromFile("11.bmp"));
images[12] = new Bitmap(Bitmap.FromFile("12.bmp"));
images[13] = new Bitmap(Bitmap.FromFile("13.bmp"));
images[14] = new Bitmap(Bitmap.FromFile("14.bmp"));
images[15] = new Bitmap(Bitmap.FromFile("15.bmp"));
images[16] = new Bitmap(Bitmap.FromFile("16.bmp"));
images[17] = new Bitmap(Bitmap.FromFile("17.bmp"));
images[18] = new Bitmap(Bitmap.FromFile("18.bmp"));
images[19] = new Bitmap(Bitmap.FromFile("19.bmp"));
images[20] = new Bitmap(Bitmap.FromFile("20.bmp"));
images[21] = new Bitmap(Bitmap.FromFile("21.bmp"));
images[22] = new Bitmap(Bitmap.FromFile("22.bmp"));
images[23] = new Bitmap(Bitmap.FromFile("23.bmp"));
images[24] = new Bitmap(Bitmap.FromFile("24.bmp"));
images[25] = new Bitmap(Bitmap.FromFile("25.bmp"));
images[26] = new Bitmap(Bitmap.FromFile("26.bmp"));
images[27] = new Bitmap(Bitmap.FromFile("27.bmp"));
images[28] = new Bitmap(Bitmap.FromFile("28.bmp"));
images[29] = new Bitmap(Bitmap.FromFile("29.bmp"));
}
private void timer1_Tick(object sender, EventArgs e)
{
if (timeKeeper == 30)
{
nextImage();
timeKeeper = 0;
}
else
{
timeKeeper++;
}
}
private void button1_Click(object sender, EventArgs e)
{
timer1.Start();
}
private void button2_Click(object sender, EventArgs e)
{
timer1.Stop();
}
private void nextImage()
{
int randNum = RandomNumber(0, 29);
imageArea.Image = images[randNum];
}
private int RandomNumber(int min, int max)
{
Random random = new Random();
return random.Next(min, max);
}
}
}
How would i go about doing this?
|
|
|
|
|
List<int> num = new List<int>();
private void nextImage()
{
int randNum = 0;
do
{
randNum = RandomNumber(0, 29);
}while(num.Contains(randNum));
num.Add(randNum);
imageArea.Image = images[randNum];
}

It is not completely obvious how that avoids duplicates. 
I would be inclined to collect images, not numbers; and pick one out of an "available" collection, not stuff them in a "used" collection.
|
|
|
|
|
Not the best, but neither was the original code
I agree that a lot of duplicate typing could have been avoided.

Did you notice some similarity between those lines? Take advantage of it, write a simple 2-line loop that does exactly the same, saving over 1000 characters (and keystrokes?).
2.
How would you do it by hand?
3.
Hint: forget about arrays, this is another great place for a collection. Look at List<Bitmap>
|
|
|
|

How about loading your images into a List<Bitmap>. Apply a random Sort algorithm, then create a Queue<Bitmap> from the list.
Now you can just dequeue each image as you display it.

Use a List, pick a random index (0 to Count-1 ), display and remove that image, repeat until empty.

Yes, and while we're at it: Why load all these bitmaps in advance at all? I would only load the one currently selected for display. For selection an array of filenames will suffice. This will go a little easier on the memory.
With 30 bitmaps this may not appear important, but still it is a waste of memory. Ans when one day the program is expanded to support 300 bitmaps (or 30000, 3000000 ...) you will get to see something I have not seen since the days of the old C64: An out of memory exception.
A while ago he asked me what he should have printed on my business cards. I said 'Wizard'.
I read books which nobody else understand. Then I do something which nobody understands. After that the computer does something which nobody understands. When asked, I say things about the results which nobody understand. But everybody expects miracles from me on a regular basis. Looks to me like the classical definition of a wizard.

Hi
I would try the following approach. Create the class in which you store the bitmap and a boolean field, which tells you if the image was already shown:
public class ImageItem
{
private Bitmap _image;
public bool Shown{get;set;}
public ImageItem(Bitmap image)
{
_image = image;
Shown = false;
}
}
private void timer1_Tick(object sender, EventArgs e)
{
if(images.Any(image => image.Shown == false))
{
nextImage()
}
else
{
}
}
private void nextImage(Bitmap image)
{
int randNumber;
do
{
randNumber = RandomNumber(0, 29);
}while(images[randNumber].Shown != false)
images[randNumber].Shown = true;
imageArea.Image = images[randNumber];
}
I typed the code directly to the page(without visual studio) so I hope I didn't make any typos.

Hey sorry I didn't even know that is a bad thing. I just saw a question and offered to help.
|
|
|
|

How do i declare an array that is one-dimensional and contains 30 bitmaps? The bitmaps are loaded from picture files on my hard disk.
|
|
|
|
|
Bitmap[] bitmaps = new Bitmap[30];

An array is an array, it isn't special just because it holds Bitmaps.
I suggest you get your C# book and study it (again).

Nothing really. That is exactly why I've used parentheses.
Now if I had be sure, I could have left out again entirely.

I am using this code on combo value change but it's not saving to the XML when the user navigates quickly..
xml_document.SelectSingleNode("/Resume/Detail/ReferencesTitle").InnerText = (string)cboTitle.EditValue;
xml_document.Save(public_var.file_name);
is there any way to lock the application until the above process is completed?

You don't want to lock the application but rather synchronize access to the resource. You can use many synchronization objects for this, like a Monitor or Mutex.

any example or resource for such case (writing to xml)? thx
