Get page number of IndirectObject in ABCPdf - pdf

I have a script which processes indirect objects from the object soup (it processes the images of the PDF).
So, I have the IndirectObject, and I need the page number on which it is:
var indiObj = sourceDoc.ObjectSoup[objectToProcess];
I have tried to use sourceDoc.GetInfo(indiObj.ID, "whatever"); but I have no idea which property to use as type, because I couldn't find any documentation of the list of possible properties.

I asked about the version because I'm working with version 7 :(
It's an interesting question (IMHO). I thought first that this could be useful:
oDoc.ObjectSoup.Catalog.Pages.GetPageArray
But, altough you get the pages, you can't get the object soup for each page (at least in version 7) .....
So, maybe, you can try something like this, as PDF code in 'objects soup' it's order from top to botton:
Dim oDoc As New WebSupergoo.ABCpdf7.Doc
Using oDoc
oDoc.Read(path_to_your_PDF)
Dim iPage As Integer = 0
Dim sType As String
For iAux As Integer = 0 To oDoc.ObjectSoup.Count - 1
sType = oDoc.ObjectSoup(iAux).GetType.ToString()
Select Case sType
Case "WebSupergoo.ABCpdf7.Objects.Page"
iPage += 1
Debug.Print(vbNewLine & "Page " & iPage.ToString & " detected")
Case "WebSupergoo.ABCpdf7.Objects.PixMap"
Dim oPDFImg As WebSupergoo.ABCpdf7.Objects.PixMap
oPDFImg = CType(oDoc.ObjectSoup(iAux), WebSupergoo.ABCpdf7.Objects.PixMap)
Debug.Print(vbNewLine & "Image on page " & iPage.ToString & " -> ID " & oPDFImg.ID.ToString)
End Select
Next
End Using
You can use a "typeof" instead of that Select Case (change 'ABCpdf7' to 'ABCpdf9', anyway). Hope it helps.

FileExist returns false

I have a folder with 700+ .jpgs. I also have a Textbox with one filename per line.
I want to check which file does not exist in the folder, but should be there.
This is my code:
Dim Counter As Integer = 0
For Each Line As String In tbFileNames.Lines
Counter = Counter + 1
If (IO.File.Exists(tbFolder.Text & "\" & tbFileNames.Lines(Counter - 1).ToString & ".jpg")) = False Then
tbNotExistingFiles.Text = tbNotExistingFiles.Text & vbNewLine & (tbFileNames.Lines(Counter - 1).ToString)
Else
End If
Next
Problem: I get more than 300 "missing" files, but there should be only 7. When I search for the output filenames, they are in the folder, so the FileExists functions returns false, but it shouldn't.
Where is the problem? Is it the amount of files?
According to this line:
If (IO.File.Exists(tbFolder.Text & "\" & tbFileNames.Lines(Counter - 1).ToString & ".jpg")) = False
Which can be interpreted as:
The tbFolder TextBox contains the directory's path where the images are located.
The tbFileNames TextBox contains the main and complete file names. One file name per line.
Appending the extension & ".jpg" means that the file names in the tbFileNames TextBox are without extensions. And,
You need to get a list of the missing files in that directory and show the result in the tbNotExistingFiles TextBox.
If my interpretation is correct, then you can achieve that using the extension methods like:
Imports System.IO
'...
Dim missingFiles = tbFileNames.Lines.
Select(Function(x) $"{x.ToLower}.jpg").
Except(Directory.GetFiles(tbFolder.Text).
Select(Function(x) Path.GetFileName(x.ToLower)))
tbNotExistingFiles.Text = String.Join(ControlChars.NewLine, missingFiles)
Or by a LINQ query:
Dim missingFiles = From x In tbFileNames.Lines
Where (
Aggregate y In Directory.EnumerateFiles(tbFolder.Text)
Where Path.GetFileName(y).ToLower.Equals($"{x.ToLower}.jpg")
Into Count()
) = 0
Select x
'Alternative to tbNotExistingFiles.Text = ...
tbNotExistingFiles.Lines = missingFiles.ToArray
Note that, there's no need nor use for the File.Exists(..) function in the preceding snippets. Just in case you prefer your approach using For..Loop and File.Exists(..) function, then you can do:
Dim missingFiles As New List(Of String)
For Each line In tbFileNames.Lines
If Not File.Exists(Path.Combine(tbFolder.Text, $"{line}.jpg")) Then
missingFiles.Add(line)
End If
Next
tbNotExistingFiles.Lines = missingFiles.ToArray

Connecting to Access from Excel, then create table from txt file

I am writing VBA code for an Excel workbook. I would like to be able to open a connection with an Access database, and then import a txt file (pipe delimited) and create a new table in the database from this txt file. I have searched everywhere but to no avail. I have only been able to find VBA code that will accomplish this from within Access itself, rather than from Excel. Please help! Thank you
Google "Open access database from excel VBA" and you'll find lots of resources. Here's the general idea though:
Dim db As Access.Application
Public Sub OpenDB()
Set db = New Access.Application
db.OpenCurrentDatabase "C:\My Documents\db2.mdb"
db.Application.Visible = True
End Sub
You can also use a data access technology like ODBC or ADODB. I'd look into those if you're planning more extensive functionality. Good luck!
I had to do this exact same problem. You have a large problem presented in a small question here, but here is my solution to the hardest hurdle. You first parse each line of the text file into an array:
Function ParseLineEntry(LineEntry As String) As Variant
'Take a text file string and parse it into individual elements in an array.
Dim NumFields As Integer, LastFieldStart As Integer
Dim LineFieldArray() As Variant
Dim i As Long, j As Long
'Determine how many delimitations there are. My data always had the format
'data1|data2|data3|...|dataN|, so there was always at least one field.
NumFields = 0
For I = 1 To Len(LineEntry)
If Mid(LineEntry, i, 1) = "|" Then NumFields = NumFields + 1
Next i
ReDim LineFieldArray(1 To NumFields)
'Parse out each element from the string and assign it into the appropriate array value
LastFieldStart = 1
For i = 1 to NumFields
For j = LastFieldStart To Len(LineEntry)
If Mid(LineEntry, j , 1) = "|" Then
LineFieldArray(i) = Mid(LineEntry, LastFieldStart, j - LastFieldStart)
LastFieldStart = j + 1
Exit For
End If
Next j
Next i
ParseLineEntry = LineFieldArray
End Function
You then use another routine to add the connection in (I am using ADODB). My format for entries was TableName|Field1Value|Field2Value|...|FieldNValue|:
Dim InsertDataCommand as String
'LineArray = array populated by ParseLineEntry
InsertDataCommand = "INSERT INTO " & LineArray(1) & " VALUES ("
For i = 2 To UBound(LineArray)
If i = UBound(LineArray) Then
InsertDataCommand = InsertDataCommand & "'" & LineArray(i) & "'" & ")"
Else
InsertDataCommand = InsertDataCommand & LineArray(i) & ", "
End If
Next i
Just keep in mind that you will have to build some case handling into this. For example, if you have an empty value (e.g. Val1|Val2||Val4) and it is a string, you can enter "" which will already be in the ParseLineEntry array. However, if you are entering this into a number column it will fail on you, you have to insert "Null" instead inside the string. Also, if you are adding any strings with an apostrophe, you will have to change it to a ''. In sum, I had to go through my lines character by character to find these issues, but the concept is demonstrated.
I built the table programmatically too using the same parsing function, but of this .csv format: TableName|Field1Name|Field1Type|Field1Size|...|.
Again, this is a big problem you are tackling, but I hope this answer helps you with the less straight forward parts.

FileInfo returning wrong value?

Okay, so I'm working in VB.NET, manually writing error logs to log files (yes, I know, I didn't make the call). Now, if the files are over an arbitrary size, when the function goes to write out the new error data, it should start a new file with a new file name.
Here's the function:
Dim listener As New Logging.FileLogTraceListener
listener.CustomLocation = System.Configuration.ConfigurationManager.AppSettings("LogDir")
Dim loc As String = DateTime.UtcNow.Year.ToString + DateTime.UtcNow.Month.ToString + DateTime.UtcNow.Day.ToString + DateTime.UtcNow.Hour.ToString + DateTime.UtcNow.Minute.ToString
listener.BaseFileName = loc
Dim logFolder As String
Dim source As String
logFolder = ConfigurationManager.AppSettings("LogDir")
If ex.Data.Item("Source") Is Nothing Then
source = ex.Source
Else
source = ex.Data.Item("Source").ToString
End If
Dim errorFileInfo As New FileInfo(listener.FullLogFileName)
Dim errorLengthInBytes As Long = errorFileInfo.Length
If (errorLengthInBytes > CType(System.Configuration.ConfigurationManager.AppSettings("maxFileSizeInBytes"), Long)) Then
listener.BaseFileName = listener.BaseFileName + "1"
End If
Dim msg As New System.Text.StringBuilder
If String.IsNullOrEmpty(logFolder) Then logFolder = ConfigurationManager.AppSettings("LogDir")
msg.Append(vbCrLf & "Exception" & vbCrLf)
msg.Append(vbTab & String.Concat("App: AppMonitor | Time: ", Date.Now.ToString) & vbCrLf)
msg.Append(vbTab & String.Concat("Source: ", source, " | Message: ", ex.Message) & vbCrLf)
msg.Append(vbTab & "Stack: " & ex.StackTrace & vbCrLf)
listener.Write(msg.ToString())
listener.Flush()
listener.Close()
I have this executing in a loop for testing purposes, so I can see what happens when it gets (say) 10000 errors in all at once. Again, I know there are better ways to handle this systemically, but this was the code I was told to implement.
How can I reliably get the size of the log file before writing to it, as I try to do above?
Well, as with many things, the answer to this turned out to be "did you read your own code closely" with a side order of "eat something, you need to fix your blood sugar."
On review, I saw that I was always checking BaseFileName and, if it was over the arbitrary limit, appending a character and writing to that file. What I didn't do was check to see if that file or, indeed, other more recent files existed. I've solved the issue be grabbing a directory list of all the files matching the "BaseFileName*" argument in Directory.GetFiles and selecting the most recently accessed one. That ensures that the logger will always select the more current file to write to or -if necessary- use as the base-name for another appended character.
Here's that code:
Dim directoryFiles() As String = Directory.GetFiles(listener.Location.ToString(), listener.BaseFileName + "*")
Dim targetFile As String = directoryFiles(0)
For j As Integer = 1 To directoryFiles.Count - 1 Step 1
Dim targetFileInfo As New FileInfo(targetFile)
Dim compareInfo As New FileInfo(directoryFiles(j))
If (targetFileInfo.LastAccessTimeUtc < compareInfo.LastAccessTimeUtc) Then
targetFile = directoryFiles(j)
End If
Next
Dim errorFileInfo As New FileInfo(listener.Location.ToString() + targetFile)
Dim errorLengthInBytes As Long = errorFileInfo.Length

for loop : string & number without keep adding &

I'm learning for loop and I cannot get this problem fixed.
The problems are in the following codes.
dim rt as integer = 2
dim i As Integer = 0
dim currentpg as string = "http://homepg.com/"
For i = 0 To rt
currentpg = currentpg & "?pg=" & i
messagebox.show(currentpg)
next
'I hoped to get the following results
http://homepg.com/?pg=0
http://homepg.com/?pg=1
http://homepg.com/?pg=2
'but instead I'm getting this
http://homepg.com/?pg=0
http://homepg.com/?pg=0?pg=0
http://homepg.com/?pg=0?pg=0?pg=0
Please help me
Thank you.
You probably need something like this:
Dim basepg as string = "http://homepg.com/"
For i = 0 To rt
Dim currentpg As String = basepg & "?pg=" & i
messagebox.show(currentpg)
Next
Although a proper approach would be to accumulate results into a List(Of String), and then display in a messagebox once (or a textbox/file, if too many results). You don't want to bug user for every URL (what if there are 100 of them?). They would get tired of clicking OK.
First of all, you went wrong while copying the output of the buggy code. Here is the real one.
http://homepg.com/?pg=0
http://homepg.com/?pg=0?pg=1
http://homepg.com/?pg=0?pg=1?pg=2
It does not work because currentpg should be a constant but it is changed on each iteration.
Do not set, just get.
MessageBox.Show(currentpg & "?pg=" & i)
Or you can use another variable to make it more readable.
Dim newpg As String = currentpg & "?pg=" & i
MessageBox.Show(newpg)
Also, your code is inefficient. I suggest you to change it like this.
Dim iterations As Integer = 2
Dim prefix As String = "http://homepg.com/?pg="
For index As Integer = 0 To iterations
MessageBox.Show(prefix & index)
Next

bullet points in Access 2010 Report

I'm working on changing an Access 2010 report. There is a portion of the report that reads in Raw Data from a SharePoint field called "Notes" that has comments for each record. Within the "notes" field, there can be several sentences. I need to find a way to separate those sentences into a bullet point per sentence in my report.
I'm trying to come up with a clever way to do so. I can get the data entry folks to use a symbol of some sort in the raw that signifies the need for a new bullet. This way, in my Report Expression (or perhaps via VBA), I can get it separated... but how?
Any thoughts?
The memo data field in MS Access can be set to Rich Text as a property, so:
UPDATE Table1
SET Table1.AMemo = "<ul><li>" &
IIf(InStr([AMemo],".")>0,
Replace(Mid([AMemo],1,Len([AMemo])-1),".","</li>"),[AMemo]) & "</li></ul>"
In its most rudimentary form you could do something like the following. Is splits the [Notes] text on ". " and creates a separate "point" for each sentence.

VBA Code:
Option Compare Database
Option Explicit
Public Function SplitNoteText(RawText As Variant) As Variant
Dim rtn As Variant, StringArray() As String, Point As Variant
Const BulletChar = "-"
rtn = Null
If Not IsNull(RawText) Then
rtn = ""
StringArray = Split(RawText, ". ", -1, vbBinaryCompare)
For Each Point In StringArray
If Len(Point) > 0 Then
If Len(rtn) > 0 Then
rtn = rtn & vbCrLf & vbCrLf
End If
rtn = rtn & BulletChar & " " & Point
If Right(Point, 1) <> "." Then
' add back the period that got "consumed" in the Split
rtn = rtn & "."
End If
End If
Next
End If
SplitNoteText = rtn
End Function
Test query:
SELECT SlideNumber, Notes, SplitNoteText(Notes) AS Points FROM SharePointData;
