Not able to copy specific pages of word document

I am trying to cut specific pages of my word document(.docx), say 2, 4. I am using for loop to traverse as per the page gave splitting it based on ,.Below is the code for the same
if (startEnd.Contains(','))
{
arrSpecificPage = startEnd.Split(',');
for (int i = 0; i < arrSpecificPage.Length; i++)
{
range.Start = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).Start;
range.End = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).End;
range.Copy();
newDocument.Range().Paste();
}
newDocument.SaveAs(outputSplitDocpath);
}
but the issue with this code is that its just copying the last page only to the new document i.e 4 in this case. How to add 2 as well? What's wrong in the code?

Since you always specify the entire document "range" as the target, each time you paste the entire content of the document is replaced.
It's correct that you work with a Range object and not with a selection, but it helps if you think about a Range like a selection. If you select everything (Ctrl+A) then paste, what was selected is replaced by what is pasted. Whatever is assigned to a Range will replace the content of the Range.
The way to solve this is to "collapse" the Range - think of it like pressing the Right-arrow or left-arrow key to "collapse" a selection to its start or end point. In the object model, this is the Collapse method that takes a parameter indicating whether to collapse to the start or end point (see the code below).
Note that I've also changed the code to use document.Content instead of Document.Range. Content is a property that returns the entire body of the document; Rangeis a method that expects a start and end point defining a Range. Using the property is the preferred method for the entire document.
if (startEnd.Contains(','))
{
arrSpecificPage = startEnd.Split(',');
for (int i = 0; i < arrSpecificPage.Length; i++)
{
range.Start = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).Start;
range.End = doc.GoTo(WdGoToItem.wdGoToPage, WdGoToDirection.wdGoToAbsolute, arrSpecificPage[i]).End;
range.Copy();
Word.Range targetRange = newDocument.Content
targetRange.Collapse(Word.WdCollapseDirection.wdCollapseEnd);
targetRange.Paste();
}
newDocument.SaveAs(outputSplitDocpath);
}

Using DataGridView in Visual Studio C#

I have a string that contains: "# of rows, # of columns, Row'X'Col'X'=Serial#, ...
How do I create a DataGrid table with the number of rows and columns defined, and then place the serial #s into the grid.
Examples:
2,1,R1C1=111,R2C1=112,
2,2,R1C1=211,R1C2=212,R2C1=213,R2C2=214,
thanks

Below is code that does what you are asking; however I must point out some problems with this approach. First, getting the total rows and cols from the first two elements in order to create your table is risky. If that data is wrong, this code will most likely crash or possibly omit data. Example if the input is: 2,2,RXCX=.., RXCX=.., RXCX=.., RXCX=..,RXCX=, RXCX=… This line will only get the first 4 values.
Worse… this will crash… if the input is 2,2,RXCX=.., RXCX=.. Then it will crash when you try to access the 4th element in the splitArray because there isn’t a 4th element. Either way is not good.
My point is to be safe… it would be a better approach to see how much data is actually there before you create the grid. You could get how many items there are with StringArray.Length minus the first two elements. These elements will define the dimensions and allow you to check their validity. This will make sure your loops won’t go out of bounds because the supplied data was wrong. It seems redundant and error prone to supply the dimension values when you can get that info from the data itself.
I still am not 100% sure what you want to accomplish here. It looks like a search of some form. This is what I am picturing…
Looking at your (previous) screen shots it appears to me that after you type into the Serial # text box and click the “Search Txt Files” button it will search for data that came from the input string i.e. “PLX51…” and then have the grid display the “filtered” results that match (or are LIKE) what’s in the Serial # textbox. If this is true, I would ignore the RXCX vales and put the data in a single column. Then wire up an OnKeyPress event for the text box to filter the grid whenever the user types into the Serial # text box.
Otherwise I am lost as to why you would need to create the data in the fashion described. Just because the input has unnecessary data… doesn’t mean you have to use it. Just a thought.
string inputString = "2,2,R1C1=211,R1C2=212,R2C1=213,R2C2=214";
string[] splitArray = inputString.Split(',');
int totalRows = int.Parse(splitArray[0]);
int totalCols = int.Parse(splitArray[1]);
int itemIndex = 2;
// add the columns
for (int i = 0; i < totalCols; i++)
{
dataGridView1.Columns.Add("Col", "Col");
}
// add the rows
dataGridView1.Rows.Add(totalRows);
for (int i = 0; i < totalRows; i++)
{
for (int j = 0; j < totalCols; j++)
{
dataGridView1.Rows[i].Cells[j].Value = splitArray[itemIndex];
itemIndex++;
}
}

Selecting text and changing it's color on a line of a RichTextBox

Good Afternoon. I am new to stack overflow as a poster but have referenced it for years. I have been researching this problem of mine for about 2 weeks and while I've seen solutions that are close I still am left with an issue.
I am writing a C# gui that reads in an assembly code file and highlights different text items for further processing via another program. My form has a RichTextBox that the text is displayed in. In the case below I am trying to select the text at the location of the ‘;’ until the end of the line and change the text to color red. Here is the code that I am using.
Please note: The files that are read in by the program are of inconsistent length, not all lines are formatted the same so I cannot simply search for the ';' and operate on that.
On another post a member has given an extension method for AppendText which I have gotten to work perfectly except for the original text is still present along with my reformatted text. Here is the link to that site:
How to use multi color in richtextbox
// Loop that it all runs in
Foreach (var line in inArray)
{
// getting the index of the ‘;’ assembly comments
int cmntIndex = line.LastIndexOf(';');
// getting the index of where I am in the rtb at this time.
int rtbIndex = rtb.GetFirstCharIndexOfCurrentLine();
// just making sure I have a valid index
if (cmntIndex != -1)
{
// using rtb.select to only select the desired
// text but for some reason I get it all
rtb.Select(cmntIndex + rtbIndex, rtb.SelectionLength);
rtb.SelectionColor = Color.Red;
}
}
Below is the sample assembly code from a file in it's original form all the text is black:
;;TAG SOMETHING, SOMEONE START
ASSEMBLY CODE ; Assembly comments
ASSEMBLY CODE ; Assembly comments
ASSEMBLY CODE ; Assembly comments
;;TAG SOMETHING, SOMEONE FINISH
When rtb.GetFirstCharIndexOfCurrentLine() is called it returns a valid index of the RTB and I imagine that if I add the value returned by line.LastIndexOf(';') I will then be able to just select the text above that looks like ; Assembly comments and turn it red.
What does happen is that the entire line turns red.
When I use the AppendText method above I get
ASSEMBLY CODE (this is black) ; Assembly comments (this is red) (the rest is black) ASSEMBLY CODE ; Assembly comments
The black code is the exact same code as the recolored text. In this case I need to know how to clear the line in the RTB and/or overwrite the text there. All the options that I have tried result in deletion of those lines.
Anywho, I'm sure that was lengthy but I'm really stumped here and would greatly appreciate advice.

I hope I've understood you correctly.
This loops over each line in the richtextbox, works out which lines are the assembly comments, then makes everything red after the ";"
With FOREACH loop as requested
To use a foreach loop you simply need to keep track of the index manually like so:
// Index
int index = 0;
// Loop over each line
foreach (string line in richTextBox1.Lines)
{
// Ignore the non-assembly lines
if (line.Substring(0, 2) != ";;")
{
// Start position
int start = (richTextBox1.GetFirstCharIndexFromLine(index) + line.LastIndexOf(";") + 1);
// Length
int length = line.Substring(line.LastIndexOf(";"), (line.Length - (line.LastIndexOf(";")))).Length;
// Make the selection
richTextBox1.SelectionStart = start;
richTextBox1.SelectionLength = length;
// Change the colour
richTextBox1.SelectionColor = Color.Red;
}
// Increase index
index++;
}
With FOR loop
// Loop over each line
for(int i = 0; i < richTextBox1.Lines.Count(); i++)
{
// Current line text
string currentLine = richTextBox1.Lines[i];
// Ignore the non-assembly lines
if (currentLine.Substring(0, 2) != ";;")
{
// Start position
int start = (richTextBox1.GetFirstCharIndexFromLine(i) + currentLine.LastIndexOf(";") + 1);
// Length
int length = currentLine.Substring(currentLine.LastIndexOf(";"), (currentLine.Length - (currentLine.LastIndexOf(";")))).Length;
// Make the selection
richTextBox1.SelectionStart = start;
richTextBox1.SelectionLength = length;
// Change the colour
richTextBox1.SelectionColor = Color.Red;
}
}
Edit:
Re-reading your question I'm confused as to whether you wanted to make the ; red as well.
If you do remove the +1 from this line:
int start = (richTextBox1.GetFirstCharIndexFromLine(i) + currentLine.LastIndexOf(";") + 1);

Private Sub RichTextBox1_Click(sender As Object, e As EventArgs) Handles RichTextBox1.Click
Dim MyInt1 As Integer
Dim MyInt2 As Integer
' Reset your RTB back color to white at each click
RichTextBox1.SelectionBackColor = Color.White
' Define the nth first character number of the line you clicked
MyInt1 = RichTextBox1.GetFirstCharIndexOfCurrentLine()
' use that nth to find the line number in the RTB
MyInt2 = RichTextBox1.GetLineFromCharIndex(MyInt1)
'Select the line using an array property of RTB (RichTextBox1.Lines())
RichTextBox1.Select(MyInt1, RichTextBox1.Lines(MyInt2).Length)
' This line would be for font color change : RichTextBox1.SelectionColor = Color.Maroon
' This one changes back color :
RichTextBox1.SelectionBackColor = Color.Yellow
End Sub
' There are a few bugs inherent to the rtb.select method
' It bugs if a line wraps, or fails on an "http" line... probably more.
(I just noticed the default stackoverflow.com character colors on my above code are not correct for comment lines and others.)

Deselect text in RichTextBox

I have a RichTextBox with a search box under it. I use the following code for the search functionality:
TabPage activePage = tabs.SelectedTab;
RichTextBox xmlBox = activePage.Controls.Find("xmlBox", true).Single() as RichTextBox;
xmlBox.DeselectAll();
int index = 0;
int len = xmlBox.TextLength;
int lastIndex = xmlBox.Text.LastIndexOf(tbSearch.Text);
while (index < lastIndex)
{
xmlBox.Find(tbSearch.Text, index, len, RichTextBoxFinds.WholeWord);
xmlBox.SelectionBackColor = Color.Yellow;
index = xmlBox.Text.IndexOf(tbSearch.Text, index) + 1;
}
What I want is that lets say a user types the word User. When he types the U I want all the Us to be highlighted, etc. and then if he deletes the r I want only Use to be highlighted. I was thinking that DeselectAll() would do the trick, but this isn`t working. Any other way to do this?

DeselectAll() will simply unselect any current selection. Your code actually changed the BackColor() of previous text so you'd have to undo this...possibly by selecting everything and resetting it to the default color before again highlighting the new search value.

RichTextBox - sorting lines randomly

I want to write an application which sorts randomly line of text which I copy from a source and paste into RichTextBox area.
However, there is one condition - text is formatted (some words are in bold, underline etc.). So any suggestions? How should it look like?
I think I should use RichTextBox.Rtf or something but I am really a beginner and I appreciate every hint or example code.
Thanks

It is a bit tricky. You can retrieve the formatted RTF text lines like this
string[] rtfLines = new string[richTextBox1.Lines.Length];
for (int i = 0; i < rtfLines.Length; i++) {
int start = richTextBox1.GetFirstCharIndexFromLine(i);
int length = richTextBox1.Lines[i].Length;
richTextBox1.Select(start, length);
rtfLines[i] = richTextBox1.SelectedRtf;
}
Now you can shuffle the lines like this
var random = new Random();
rtfLines = rtfLines.OrderBy(s => random.NextDouble()).ToArray();
Clear the RichtTextBox
richTextBox1.Text = "";
Inserting the lines is best done in reverse order because it is easier to select the beginning of the text
// Insert the line which will be the last line.
richTextBox1.Select(0, 0);
richTextBox1.SelectedRtf = rtfLines[0];
// Prepend the other lines and add a line break.
for (int i = 1; i < rtfLines.Length; i++) {
richTextBox1.Select(0, 0);
// Replace the ending "}\r\n" with "\\par }\r\n". "\\par" is a line break.
richTextBox1.SelectedRtf =
rtfLines[i].Substring(0, rtfLines[i].Length - 3) + "\\par }\r\n";
}

The task seems not complicated(if I understand it correctly).
Get your clipboard into string then parse into array- use Split().
Then determine how many randon events you need and iterate through every word ; generate random number for each iteration(which should match the amount of events), intersect that number with one of the events and apply that case to that particular word. Maybe not the most efficient way to do it, but that's what comes to my mind
