Increasing sequence in one dimensional array

You're given an array of integers,in case if you see subsequence in which each following bigger than the previous on one(2 3 4 5) you have to rewrite this subsequence in the resulting array like this 2 - 5 and then the rest of the array. So in general what is expected when you have 1 2 3 5 8 10 11 12 13 14 15 the output should be something like 1-3 5 8 10-15.
I have my own idea but can't really implement it so all I managed to do is:
static void CompactArray(int[] arr)
{
int[] newArr = new int[arr.length];
int l = 0;
for (int i = 0,k=1; i <arr.length ; i+=k,k=1) {
if(arr[i+1]==arr[i]+1)
{
int j = i;
while (arr[j+1]==arr[j]+1)
{
j++;
k++;
}
if (k>1)
{
}
}
else if(k==1)
{
newArr[i] = arr[i];
}
}
In short here I walk through the array and checking if next element is sum of one and previous array element and if so I'm starting to walk as long as condition is true and after that i just rewriting elements under indices and then move to the next.
I expect that people will help me to develop my own solution by giving me suggestions instead of throwing their own based on the tools which language provides because I had that situation on the russian forum and it didn't help me, and also I hope that my explanation is clear because eng isn't my native language so sorry for possible mistakes.

If I understand the problem correctly, you just need to print the result on the screen, so I'd start with declaring the variable which will hold our result string.
var result = string.Empty
Not using other array to store the state will help us keep the code clean and much more readable.
Let's now focus on the main logic. We'd like to loop over the array.
for (int i = 0; i < array.Length; i++)
{
// Let's store the initial index of current iteration.
var beginningIndex = i;
// Jump to the next element, as long as:
// - it exists (i + 1 < array.Length)
// - and it is greater from current element by 1 (array[i] == array[i+1] - 1)
while (i + 1 < array.Length && array[i] == array[i+1] - 1)
{
i++;
}
// If the current element is the same as the one we started with, add it to the result string.
if (i == beginningIndex)
{
result += $"{array[i]} ";
}
// If it is different element, add the range from beginning element to the one we ended with.
else
{
result += $"{array[beginningIndex]}-{array[i]} ";
}
}
All that's left is printing the result:
Console.WriteLine(result)
Combining it all together would make the whole function look like:
static void CompactArray(int[] array)
{
var result = string.Empty;
for (int i = 0; i < array.Length; i++)
{
var beginningIndex = i;
while (i + 1 < array.Length && array[i] == array[i+1] - 1)
{
i++;
}
if (i == beginningIndex)
{
result += $"{array[i]} ";
}
else
{
result += $"{array[beginningIndex]}-{array[i]} ";
}
}
Console.WriteLine(result);
}

listboxes passing values from each other

I'm trying to multiply the values of 2 listboxes together and make their product appear at another list box I'm getting the results I need but the problem is when I rerun the loop using a command button the listbox removes the next instance of the first value calculated by ppc[i] * qty[i] but when I try to remove the the listBox4.Items.Remove(ppc[i] * qty[i]) it reprints the whole array again from first element to last element
string myString = textBox1.Text.ToString();
int index = listBox6.FindString(myString, -1);
int[] qty = new int[99];
int[] ppc = new int[99];
int[] gt1 = new int[99];
listBox3.Items.Add(listBox5.Items[index]);
listBox1.Items.Add(textBox2.Text.ToString());
if (index != -1)
{
listBox6.SetSelected(index, true);
listBox2.Items.Add(textBox1.Text); //name
}
listBox3.Items.Add(listBox5.Items[index]);
listBox3.Items.Remove(listBox5.Items[index]);
for (int i = 0; i != listBox2.Items.Count ; i++)
{
ppc[i] = Convert.ToInt32(listBox3.Items[i]);
qty[i] = Convert.ToInt32(listBox1.Items[i]);
listBox4.Items.Remove(ppc[i] * qty[i]);
listBox4.Items.Add((ppc[i] * qty[i]));
}

My understanding is that this loop works once, and then when it is re-run it is out of order. Are you making sure to clear listbox4 each time this loop is executed? Also since listBox2 isn't used, it is probably better not to use it for your loop bounds.
if(listBox1.Items.Count == listBox3.Items.Count)
{
int rowCount = listBox1.Items.Count;
listBox4.Items.Clear();
for (int i=0; i < rowCount; i++)
{
ppc[i] = Convert.ToInt32(listBox3.Items[i]);
qty[i] = Convert.ToInt32(listBox1.Items[i]);
listBox4.Items.Insert(i , (ppc[i] * qty[i]));
}
}

Summarize table using C# and JScript

I've written code in C# to summarize values of InvoiceTable and move those summarized values to to GroupTable in Abbyy FlexiCapture. The Software is comparatively new and does not show any error when I run it.
There are two sets of code to be written:
In TechField.
In EventHandlers.
InvoiceTable consists of:
TariffNumber
ShipQty
Amount
COO
GroupTable consists of:
HSCode
Qty
Amt
CountryOO
EventHandlers code is as follows (C#):
if (ChangedStates.Has(7)) {
int currentRow = 0;
int i;
for (i = 0; i < Document.Field("Invoice2\\InvoiceTable").Items.Count; i++) {
if (Document.Field("Invoice2\\InvoiceTable").Cell("TariffNumber", i).Value == "") {
Document.Field("Invoice2\\GroupTable").Cell("HSCode", currentRow).Value = Document.Field("Invoice2\\InvoiceTable").Cell("TariffNumber", i).Value;
Document.Field("Invoice2\\GroupTable").Cell("Amt", currentRow).Value = Document.Field("Invoice2\\InvoiceTable").Cell("Amount", i).Value;
Document.Field("Invoice2\\GroupTable").Cell("Qty", currentRow).Value = Document.Field("Invoice2\\InvoiceTable").Cell("ShipQty", i).Value;
currentRow++;
}
}
}
TechField is as follows (JScript):
for (i = 0; i < Field("ShipQty").Items.Count - 1; i++) {
for (j = i + 1; j < Field("ShipQty").Items.Count; j++) {
// if same new items are found
if (Field("TariffNumber").Items(i).Value == Field("TariffNumber").Items(j).Value && Field("CoO").Items(i).Value == Field("CoO").Items(j).Value)
{
// summarise quantities
Field("ShipQty").Items(i).Value = parseInt(Field("ShipQty").Items(i).Value) + parseInt(Field("ShipQty").Items(j).Value);
// and weights
Field("Amount").Items(i).Value = parseFloat(Field("Amount").Items(i).Value) + parseFloat(Field("Amount").Items(j).Value);
}
}
}
Condition:
In the InvoiceTable, where ever TariffNumber and COO are equal, values of ShipQty and Amount should be summarized and put into GroupTable.
The code does not show any errors but does not give the output as well. Would be great if anyone of you can help me out on this.

One thing you could try is adding a summary section to the document definition. This may require you to create a document set.
I've found it easier to create rules which are checked when the field is recognised. There's some info here: https://help.abbyy.com/en-us/flexicapture/12/distributed_administrator/docsets_settings/

Populate an array element with 2 datarows at a time

i want to populate an array element with 2 datarows at a time.
i am using javascript pausescroller and on every single array element i want to show 2 Rows in the scroller.
sample code is
Datatable tblNews;
for(int i = 0; i < tblNew.Rows.Count; i++)
{
array[i] = tblNews.Rows[i][""].ToString() + "" + tblNews.Rows[i + 1][""].ToString();
}
but problem is i am getting error that no row found at position 1;
Any solution guys

Yah, quite simply, when you're getting to the end of your tblNew.Rows.Count you're adding another one and that doesn't exist in your rows...
so a quick and dirty fix...
for(int i = 0; i < tblNew.Rows.Count-1; i++)
{
// do a quick check to make sure there is a row there to get data from
string addMe = i + 1 <= tblNews.Rows.Count-1 ? tblNews.Rows[i+1][""].ToString() : "";
array[i] = tblNews.Rows[i][""].ToString() + "" + addMe;
}

How to find a particular position of a selected item in Listbox making the Buttons Enabled in C#?

I have a list box with items like A B C D E.
I also have two buttons Move UP and Move Down with it.
I have already made their properties false in the property window (F4).
When a user selects B or all the items below then my Move Up button should get enabled. It should be disabled for A item
In the same way my Move Down button should be enabled when the user selects D or all the items above it. It should be disabled for E.
Can you please provide me the right part of code to be written here.
Thanks....

I am doing a similar thing in my app. It also handles selection of multiple items and also checks if the multiple items that are selected are continuous or not.
Here's the code:
private bool SelectionIsContiguous(ListBox lb)
{
for (int i = 0; i < lb.SelectedIndices.Count - 1; i++)
if (lb.SelectedIndices[i] < lb.SelectedIndices[i + 1] - 1)
return false;
return true;
}
private void SetMoveButtonStates()
{
if (this.listBox.SelectedIndices.Count > 0)
{
if (this.listBox.SelectedIndices.Count > 1 && !SelectionIsContiguous(this.listBox))
{
this.btnMoveUp.Enabled = false;
this.btnMoveDown.Enabled = false;
return;
}
int firstSelectedIndex = this.listBox.SelectedIndices[0];
this.btnMoveUp.Enabled = firstSelectedIndex == 0 ? false : true;
int lastIndex = this.listBox.Items.Count - 1;
int lastSelectedIndex = this.listBox.SelectedIndices[this.listBox.SelectedIndices.Count - 1];
this.btnMoveDown.Enabled = lastSelectedIndex == lastIndex ? false : true;
}
}

Handle the SelectedIndexChanged event of the ListBox. If the SelectedIndex is greater than 0, enable "move up". If it is lesser than count - 1, enable "move down"

Here's the code I use in listBox_SelectedIndexChanged:
this.moveUp.Enabled = this.listBox.SelectedIndex > 0;
this.moveDown.Enabled = this.listBox.SelectedIndex > -1 && listBox.SelectedIndex < listBox.Items.Count - 1;
Actually it's in a method called from there as the code's called when the dialog's initialised too.
