I recently upgraded my computer to Windows 10, and now one of the programs is acting weird since the upgrade.
Trying to print a page range out of a PDF, and when I print pages 1 to 100 (out of 477 pages) I get an error saying ToPage should be less than the page count even though 100 is less than 477.
If I skip the page range part and just have it print all of the pages, it works fine.
Sub PrintToPaperSync(ByVal InputfilePath As String, Optional ByVal DeleteAfter As Boolean = False)
On Error GoTo sError
Dim tError As String = ""
Dim toPage As Integer = 0
Console.WriteLine("PrintToPaper " & InputfilePath)
Dim File As String = Split(InputfilePath, "\")(Split(InputfilePath, "\").Length - 1)
Dim viewer As New Syncfusion.Windows.Forms.PdfViewer.PdfDocumentView
viewer.Load(InputfilePath)
Dim print As New System.Windows.Forms.PrintDialog()
print.Document = viewer.PrintDocument
print.Document.DocumentName = File
'print 100 pages at a time
Do While toPage < viewer.PageCount
print.Document.PrinterSettings.PrintRange = Drawing.Printing.PrintRange.SomePages
print.Document.PrinterSettings.FromPage = toPage + 1
toPage += 100
print.Document.PrinterSettings.ToPage = IIf(toPage < viewer.PageCount, toPage, viewer.PageCount)
tError = "From: " & print.Document.PrinterSettings.FromPage & " | To: " & print.Document.PrinterSettings.ToPage & " | PageCount: " & viewer.PageCount & " - "
print.Document.Print()
Application.DoEvents()
Loop
viewer.Unload()
viewer.Dispose()
Console.WriteLine("Printing: " & InputfilePath)
Exit Sub
sError:
Dim ErrorStr As String = ErrorToString()
WriteLine("PrintToPaper " & tError & " " & InputfilePath & " - " & ErrorStr)
End Sub
Full text of the error:
PrintToPaper From: 1 | To: 100 | PageCount: 477 - F:\Process\LogTag-10-30-15-104122.pdf - ToPage should be less than the page count
We want to only print 100 pages at a time, because the printer begins to slow down after 100 pages for some reason.
This printing problem is caused due to the issue with Syncfusion Control. You can contact the Syncfusion Software Support team to get the issue resolved. Please follow the below link to contact Syncfusion Support Team

I have a TextBox and it contains this text "File Was Created"
I would like to place the cursor one space over from the end of this text in the TextBox
I am trying to NOT say Simple Enough Task BUT I have wasted 2 hours with no solution
YES I know if I change the text to this "File Was Created " it will work NOT a solution
Here is the code mess I have tried
Dim L As Integer
L = tbMessage.Text.Length
L += 1
'tbMessage.Text = CStr(L)
'tbHaveTwo.Text = frmOne.vR
'Me.ActiveControl = tbMessage
'tbMessage.SelectionStart = tbMessage.Text.Length
tbMessage.SelectionStart = L
tbMessage.Select()<br/>
Here is Two updated ways to solve this issue Jimi way less code
tbMessage.Text = "File Was Created"
'This Code involves more code
'Dim str As String
'str = Mid(tbMessage.Text, tbMessage.Text.Length)
'If str <> " " Then
' tbMessage.Text = tbMessage.Text & " "
'End If
'Answer from Jimi Works Great
tbMessage.AppendText(ChrW(32))
tbMessage.SelectionStart = tbMessage.Text.Length
tbMessage.Select()
So you don't end up with a ton of spaces on the end of your message?
tbMessage.AppendText(If(tbMessage.Text.EndsWith(" "), "", " "))
tbMessage.SelectionStart = tbMessage.TextLength
tbMessage.Focus()
I have lot of documents with list number typed manually, so my intent is to remove those manual list number and the tab or space following it.
e.g
1. Text 1
1.1 Text 2
1.1.1 Text 3
1.1.1.1 Text 4
become
Text 1
Text 2
Text 3
Text 4
I'm not sure how to do this with vba and I'd really appreciate your help.
I have figured it out by using below code:
Sub RemoveManualListNumber()
Dim strInitialPar As String
Dim intSpace As Integer, intTab As Integer
Dim strFinalPar As String
Dim iPar
For iPar = 1 To ActiveDocument.Paragraphs.Count
strInitialPar = ActiveDocument.Paragraphs(iPar).Range.Text
intSpace = InStr(1, strInitialPar, " ")
intTab = InStr(1, strInitialPar, Chr(9))
Debug.Print "Paragraph " & iPar & ": " & "Index space = " & intSpace & ", Index tab = " & intTab
If intTab > 0 And intTab < intSpace Then
strFinalPar = Right(strInitialPar, Len(strInitialPar) - intTab)
Else
strFinalPar = Right(strInitialPar, Len(strInitialPar) - intSpace)
End If
ActiveDocument.Paragraphs(iPar).Range.Text = strFinalPar
Next iPar
End sub
In my window application i am using Quick pdf to find height,width of pdf.please refer the below code.But sometimes quickpdf can't able to find correct value.so i want to do the task using iTextSharp. How to find pdf height,width using iTextSharp?
Try
Dim qp1 As New iSED.QuickPDF
Dim sPDFHei, sPDFWid As Double
Dim iPgCnt As Integer
qp1.UnlockKey("6510E9D5C3938A920B3A8D7293C6DF00")

iPgCnt = qp1.PageCount
For i As Integer = 1 To iPgCnt
'MsgBox("pagecount=" & iPgCnt)
qp1.SelectPage(i)
'MsgBox("PageNumber=" & i)
sPDFHei = qp1.PageHeight : sPDFWid = qp1.PageWidth
sPDFHei = Math.Round(sPDFHei, 2) : sPDFWid = Math.Round(sPDFWid, 2)
''If sPDFWid <> 8.26 And sPDFHei <> 11.69 Then
If sPDFWid > 520 Or sPDFHei > 600 Then
MsgBox("Article PDF size should not exit 7.22 x 8.33" & vbCrLf & "Problem in template:" & i)
Exit Function
End If
Next
qp1.clear()
Checkpdfsize = True
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Information, "CheckPdfSize")
End Try
Thanks in Advance
Youll find what you need in chapter 6 of their documentation here. Its under Action by the way.
I have a logic problem, just need more brains working on this.
For Each JobNode In JobNodes
Dim Source = JobNode.SelectNodes("Source")
For Each item As System.Xml.XmlNode In Source
Dim infoReader As System.IO.FileInfo
''''Discerns whether a file or directory
If item.InnerText.Contains(".") Then 'is a file
If Dir$(item.InnerText) <> vbNullString Then
mySize += FileLen(item.InnerText)
End If
zip.AddFile(item.InnerText, "")
Dim numFiles2 = filenames.Count
mySize = BytesTO(mySize, convTo.MB)
Console.WriteLine("...Added all " & numFiles2 & " files. Total loose file collection size is " & Math.Round(mySize, 2) & " MB")
Console.WriteLine(vbCrLf)
Else 'is a directory
zip.AddDirectory(item.InnerText, GetLastDirName(item.InnerText & " "))
Dim dinfo As New DirectoryInfo(item.InnerText)
Dim sizeOfDir As Long = DirectorySize(dinfo, True)
Dim numFiles As Integer = CountFiles_FolderAndSubFolders(item.InnerText)
Console.WriteLine("...Added all " & numFiles & " files. Total directory size is {0:N2} MB", (CDbl(sizeOfDir)) / (1024 * 1024))
Console.WriteLine(vbCrLf)
End If
Next
This is part of a backup program I made. This is the part that determines if the object to be added to the zip is a file (first part of the IF statement) or a directory (ELSE part of the IF statement).
My problem is, I am trying to add this code:
Dim numFiles2 = filenames.Count
mySize = BytesTO(mySize, convTo.MB)
Console.WriteLine("...Added all " & numFiles2 & " files. Total loose file collection size is " & Math.Round(mySize, 2) & " MB")
Console.WriteLine(vbCrLf)
Just after the zip.AddFile(item.innertext,"") part. I want to add this so that I can get a console print out of the information.
The problem is, if I just put it directly after the zip.addfile(), it outputs the code directly above each time. I only want it to print out that part (directly above) once it has finished adding all of the loose files (or files added using zip.AddFile())
EDIT: adding the for loops at the top for more clarification
Add a flag and then look for it after the loop completes. It seems as though you are looping through the files instead of calling this recursively. I am guessing you have only one loop right now.
Before Loop iteration:
Dim FilesBeingAdded as Boolean = False
Dim numFiles2 as Integer = 0
Inside of iteration:
If item.InnerText.Contains(".") Then 'is a file
If FilesBeingAdded = False Then
FilesBeingAdded = true
End If
If Dir$(item.InnerText) <> vbNullString Then
mySize += FileLen(item.InnerText)
End If
zip.AddFile(item.InnerText, "")
numFiles2 +=1
Else 'is a directory
zip.AddDirectory(item.InnerText, GetLastDirName(item.InnerText & " "))
Dim dinfo As New DirectoryInfo(item.InnerText)
Dim sizeOfDir As Long = DirectorySize(dinfo, True)
Dim numFiles As Integer = CountFiles_FolderAndSubFolders(item.InnerText)
Console.WriteLine("...Added all " & numFiles & " files. Total directory size is {0:N2} MB", (CDbl(sizeOfDir)) / (1024 * 1024))
Console.WriteLine(vbCrLf)
End If
After Loop Iteration:
If FilesBeingAdded = True Then
mySize = BytesTO(mySize, convTo.MB)
Console.WriteLine("...Added all " & numFiles2 & " files. Total loose file collection size is " & Math.Round(mySize, 2) & " MB")
Console.WriteLine(vbCrLf)
mySize = 0
numFiles2 = 0
FilesBeingAdded = False
End If
So when it finishes the current iteration it will take the tally of files it added, along with the size and print it to the console. It then zeros the variables so that the next iteration of the inner loop has clean values. I am presuming you run this on more than one directory. By checking FilesBeingAdded you can be sure to avoid situations where an ugly zero count output is shown if the directory contained no files.
This solution presumes a lot about how you enter this piece of code. If my presumptions were not correct, please modify the question to enable a better solution.
Hello Stack overflow !
I'm the ultimate beginner in programming. I have some experience in php and vba, doing my own scripts as I need them, especially in excel.
Recently, for a project at works, I need to be able to scan AUTOMATICALLY (say every 2 minutes) from multiple scanners (say 2 for starters) both connected to the same computer.
I decided to use this project as a start point for me to get a feeling of Visual Basic.
So here we go, I installed visual studio express 2010 and started writing my script trying to find here and there bits of codes that could help me. I found that WIA could help with that (Twain could as well but it seems much more obscure to the newbie I am)
Anyway, I finally came up with an app that is able to automatically scan at the set interval when only one scanner is connected. The trouble arrives when I connect more than one scanner. then, the first scan occurs correctly (Scanner 1 scans, then scanner 2 scans), but when the second scan is supposed to start, nothing happens and the scanners become inaccessible (busy).
I though maybe I forgot to "release" or "disconnect" the last scanner used. Or maybe, something remains in the scanner's buffer memory ?
I have been stuck on this issue for the last 3 days and don't know how to make it work.
here is the function that scans : (i don't past the rest as it is the UI and folder management)
Public Sub scannerloop()

Please be indulgent with me, I am aware that the code is probably a nightmare for programming pros with lots of bad stuff, but it is literally my first VB program, and I am eager to learn.
So basically, the rest of the program is a form where I enter the target directory for the scan, the filenames, resolution etc, and when I click on 'start scanning', it
- runs scannerloop one first time
- starts a 'scantimer' which launches scannerloop each time it ticks.
As I said, it works perfectly with 1 scanner (files created as expected, logfile updated, etc) but as soon as I have 2 scanners, only the first scan works and then, when scanner#1 is supposed to start scanning, it doesn't and the led of scanner#2 starts blinking (as if it was scanning, but it's not scanning)
I hope someone will be able to help me.
Thanks in advance.

UPDATE - thing that I tried which may be of interest :
I just tried to add a for loop to make it scan from both scanners several times (so, independantly from the timer and the rest of the program basically) :
Dim DeviceManager1 = CreateObject("WIA.DeviceManager") 'wia device manager
For k = 1 To 3
Dim j As String = 1
For i = 1 To DeviceManager1.DeviceInfos.Count 'loop through all devices
[...]
Next i
Next k
DeviceManager1 = Nothing
That showed that the first occurence of the loop works (scans once from each scanner) but that's it, the scanners never scan the second time and start blinking, so basically exactly the same problem.
I also tried to include the Devicemanager declaration in the new loop :
For k = 1 To 3
Dim DeviceManager1 = CreateObject("WIA.DeviceManager") 'wia device manager
Dim j As String = 1
For i = 1 To DeviceManager1.DeviceInfos.Count 'loop through all devices
[...]
Next i
DeviceManager1 = Nothing
Next k
but it did not change anything.
The next thing I did wat to log the events within the loop so that I can know where exactly things stop :
Dim DeviceManager1 = CreateObject("WIA.DeviceManager") 'wia device manager
Dim j As String = 1
For i = 1 To DeviceManager1.DeviceInfos.Count 'loop through all devices
If DeviceManager1.DeviceInfos(i).Type = 1 Then 'Select only scanners, not webcams etc...
'startpoint to calculate how long it is to scan
Dim ScanStart = DateAndTime.Second(Now) + (DateAndTime.Minute(Now) * 60) + (DateAndTime.Hour(Now) * 3600)

Dim Scanner As WIA.Device = DeviceManager1.DeviceInfos(i).connect

it appears that things go wrong at this line :
Img = Scanner.Items(1).Transfer(fileformat) 'scans the image.
It looks like WIA is happy to switch from scanner 1 to 2 but refuses to come back to scanner 1 for the next round. also, I should precise, when the second scan is supposed to occur, scanner #2 blinks (and not 1 which surprises me).
Is it possible that scanner#2 is selected as "default scanner" or something like that and if so, is there a way to revert that ?
