  • 1. Can't get the Crystal Reports Viewer to bind with my dataset.
    Here's my VB.NET code: Dim RV As New frmReportViewer 'This is the form containing the 'Crystal Report Viewer Dim Rep As New DetailsReport 'DetailsReport is the name of my 'report. It is already imported 'into my project Rep.SetDataSource(myDataset) 'myDataset is correct and has the 'correct number of records. RV.CrystalReportViewer1.ReportSource() = Rep 'This sets the data. RV.Show() 'Show the form. The Crystal Report Viewer ignores the dataset and always just displays all the data from the given table that was used to design the report. The Dataset is correct but for some reason it won't take in the report. Is there some setting within Crystal Reports that I need to look at? Thanks, Dominic Isaia XXXX@XXXXX.COM
  • 2. Calculate version number for comparison?
    I have two version numbers - one for my application and another from a manifest, database, whatever - that isn't important. Now that I have these two version numbers (in the form major.minor.build.revision) I want to compare one to see if it is less than the other. Is there any calculation I can do to convert a version number to a 'real' number so that I can compare it easily? I've fiddled around with various methods but nothing works for everything. I have tried to compare the individual elements one at a time, but there are so many deviations that it again doesn't work for everything (i.e. 1.9.9.0 is higher than 1.9.8.920). There seems like there should be some mathematical way to convert this to some kind of number so my code could simply say something like "if current_converted_version < new_converted_version then ...'. Anyone good mathematicians out there?? :-) Tom

TextFieldParser - reading tab delimited file

Postby al jones » Fri, 22 Sep 2006 20:34:05 GMT

I using textfieldparser to read a data file. which contains, for example:

Amond Szegi	Amondo Szegi
andr nossek	Andr Nossek
 Characte	Character

Note the vowels with diacriticals and the copyright symbol - it is dropping
these (and other similar) characters which fall outside ascii range
(apparently)

The code is simple and looks like:
        Using MyReader As New TextFieldParser(Application.StartupPath &
"\designers.txt")
            MyReader.TextFieldType = FileIO.FieldType.Delimited
            MyReader.CommentTokens = New String() {"#"}
            MyReader.Delimiters = New String() {vbTab}
            MyReader.TrimWhiteSpace = True
            Dim currentRow As String()
            intElement = 0
            While Not MyReader.EndOfData
                Try
                    currentRow = MyReader.ReadFields()
                    If Microsoft.VisualBasic.Left(currentRow(0), 7) =
"UNKNOWN" Then
                        strUnknownDesigner = currentRow(1)
                        Continue While
                    End If
                    arDesigner(intElement, 0) = currentRow(0)
                    arDesigner(intElement, 1) = currentRow(1)
                    arDesignerCounter(intElement) = 0
                    intElement += 1
                Catch ex As MalformedLineException
                    MsgBox("Designer Line " & ex.Message & "is not valid
and will be skipped.")
                End Try
            End While
        End Using

I can see any reason in the documentation for it dropping copyright or
the French and German (etc vowels with accents.

Comments or suggestions anyone??

Thanks //al

It appears to be an encoding problem where the file uses (I'm guessing) 
ISO-8859-1 or maybe Windows-1252 whereas the .NET framework defaults to 
Unicode. Does a TextFieldParser have a setting for that (or have a 
.BaseClass that does)?

Or perhaps you can arrange for the file to be encoded with Unicode?

Possibly my confusion is from the fact that I maintain these files (there
are three of them) within VS 2005 so I would have epected them to be
unicode. The characters exist within the files (the three line examples are
cut & paste from the file itself) so I don't understand why reading them
would literally eliminate the characters.

I've been over the TextFieldParser docs and see nothing that indicates that
it shouldn't take the data as presented.

Try OrchidGrid control, which can pase/import data from delimited files.

3.Problem reading Unicode from a tab-delimited file

Hi,
I have a spreadsheet that contains multiple languages. Per project
requirements I have saved this speadsheet in a tab-delimted format
using Excel 2007. I have been able to pretty much get all the
charaters correct when reading the file. I will also have to parse
Japanese from this, which I have not been able to do. I cannot read
the 3 byte characters from the file correctly for some reason. I have
an example here showing 2 characters for simplicity.

??

I get the correct value for ? but not for ? The value of ?should be
2019, instead I getting something that just displays a box in the
debugger, some value around 65k.
Note in the code snippet below, If I pass the unicodeString to the
foreach (Byte b in encodedBytes)
it works perfectly, outs the correct values for the charaters.. I have
a tab-delimted file that contains the same characters. When I open
that file and reead from it, the ?is correct, but the ?is not.
Likewise for the Japanese characters I am tring to read. Almost seems
like the issue is the file open() or the readline().
Any help and code examples would be appreciated.
Thanks
Jeff

5.Reading Tab Delimited Data With Imbedded Double Quotes

I can't get the Microsoft Jet OLEDB 4.0 driver to read a tab delimited 
text file that has double quotes imbedded in the data. For example

Field1 | Field2 | Field3
Bob | Pant Size 34" Waist | 22

(I'm using a vertical bar here for the tab)

Field2 will contain: Pant Size 34
Field3 will contain: Waist

I have a schema.ini

[MyFile.txt]
ColNameHeader=True
Format=TabDelimited
MaxScanRows=25
CharacterSet=OEM

How do I get it to read the double quote?
