I have the field Note from table Record Link that i want to display in an rdlc report. How can i include it in the dataset to loop into the BLOB field to extract the text value ? Using NAV90
Thanks
Notes are stored as Binary Text.
You need to use .NET to read out the value into a string.
From the .NET side of things you'll need:
BinaryReader from 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.IO.BinaryReader
Encoding from 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Text.Encoding
As for reading the actual BLOB into a string:
RecordLink.Note.CREATEINSTREAM(InStream);
BinaryReader := BinaryReader.BinaryReader(InStream,Encoding.UTF8,FALSE);
MESSAGE('Your note text is %1',BinaryReader.ReadString);
The text can be retrieved without the use of DotNet variables.
CommentStream : InStream;
CommentText : Text;
good:
tbl.CALCFIELDS(Comments);
tbl.Comments.CREATEINSTREAM(CommentStream);
CommentStream.READTEXT(CommentText);
In my case including the text encoding parameter like this wasn't working. It was for a while, but stopped working. The reason for the inconsistency eludes me, but nonetheless removing the text encoding argument fixed it.
bad:
tbl.CALCFIELDS(Comments);
tbl.Comments.CREATEINSTREAM(CommentStream, TEXTENCODING::UTF8);
CommentStream.READTEXT(CommentText);
B
igTextVar.ADDTEXT('Text which has lenghth grater than 1024...');
StringHelper: System.String.'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' (DotNet Var)
DataItem.Column.SourceExpression = StringHelper.Copy(FORMAT(BigTextVar))
This is the trick to pass BigText into Report RDLC layout without using more Column
I tried in Dynamics NAV 2017 and it works well!

How do you Edit a (binary EBCDIC) Mainframe file in the RecordEditor with out a Cobol Copybook.
How do you generate Java code to read the file using the RecordEditor.
Note: This is an attempt to split a question that is far to broad to give meaningful answer to
into a series of simpler Question and Answer's.
Try and avoid editing a binary file with a Cobol Copybook if at all possible. This should only be attempted as a last resort !!!.
Try and get
that Cobol copybook (or some field layout document) for the file !!!
Some general advise:
It is feasible when dealing with 10 / 20 fields in a record but not if there a thousands of fields in a Record.
Take your time do not rush the process. Try and get each step correct before moving on
Finally upgrade to the latest version of the RecordEditor (currently 0.98.4)
This process will also work for normal Text file as well
RecordEditor Layout Wizard
To start the wizard select option Record Layouts >>> Layout Wizard.
File Structure screen
The file structure screen has 3 purposes:
Get the File structure - It could be Fixed Width, VB, Windows/Unix Text file
Get the Record-Length (if it is a fixed width file).
Get the font (character-set / encoding)
The RecordEditor will try and work this out for you
Field Selection Screen
The RecordEditor will try and work out where fields start and end but
it is not perfect. You need to carefully check and correct its choices
On this screen, the fields are displayed in alternating colors
you create/delete a field by clicking on
use the Clear Fields button clear all the fields
you can change what field-types to search for using the various check box's (e.g. Mainframe Zones Decimal)
The Add Fields will do another field search
Field Definition screen
On this screen you define the field names and Types. You may need to go back to the **Field Selection Screen* to adjust the fields
Editing the file
Once the Record Layout has been defined, it can be used on the open file screen
Generating Java code
When editing your file, you can generate java~JRecord code to read the file
by selecting Generate >>> Java >>> ....
You can the enter a package-id + generate options:
and finally your sample java code is generated to read / write the
file.
I am trying to add fields from VB.Net class file to SQL database, while doing "Add Migration" It is showing "startIndex cannot be larger than length of string."
enter image description here
I had the same error message when i tried to make a migration. The cause in my case was an empty value for MigrationId for a particular migration in the _MigrationHistory table.
This field must have a value in the same format as the string parameter of the attribute [Migration("YYYYMMDDHHMMSS_SeedData")], which is described in the other answer.
Most of all you have some class in your data project with attribute Migration (maybe for seeding data or something similar) which name is not in expected format like this:
[Migration("YYYYMMDDHHMMSS_SeedData")]
Adjust the migration name to be in YYYYMMDDHHMMSS_Description format to fix the error startIndex cannot be larger than length of string.
I'm facing a problem and want to ask for a solution.
I'm working on an eclipse plugin project, in which an editor for a type of resource file is required. The resource file has similar structure like CSV file. My idea is to provide user the option to edit this type of file both in plain text format and also in an SWT table. Plain text is required for examining data and table provides more flexibility to editing such as sorting by column.
I have been able to create a MultiPageEditorPart, with one page of org.eclipse.ui.editors.text.TextEditor, and another page with a org.eclipse.swt.widgets.Table and several other widgets like search bar. The content of the resource file can be shown in the TextEditor, can also be edited and saved. On the other hand, the content can be loaded in the table too, sorting and searching all work good.
The problem is: when I edit a cell in the table, I want the change also reflected in the TextEditor, and vice versa. Since the resource file can be very large, I want the saving action happen only on the TextEditor, i.e. I don't want any modification in the table directly stored to resource file, but to mark the file dirty, but I can't figure out how. How can I for example get the content of EditorInput, check it line by line, and modify it outside TextEditor?
Or, are there more efficient ways to do this? Can anyone give any hints?
The IDocument used by the TextEditor gives you access to the document contents. Get this with something like:
IDocumentProvider provider = editor.getDocumentProvider();
IEditorInput input = editor.getEditorInput();
IDocument document = provider.getDocument(input);
IDocument has many methods for accessing lines such as:
int getLineOffset(int line);
int getLineLength(int line);
and methods for modify the text:
void replace(int offset, int length, String text);
I have a user that is storing a 'registered trademark' symbol in her name in our database and when we retrieve it when the database it renders correctly, but when we actually place it onto the website itself in HTML it renders with an extra 'A' symbol in front of it:
You can see above the database value compared to what is rendered in the PDF file. I can access the database value in the backend and edit it through vb code but I am really not sure how or what the code would be to do that as I don't want to remove all ASCII characters just the extra symbol being generated and rendered in the PDF.
Any idea how to do this would be great.
I think the Main-Problem is that you generate wrong HTML-Code by just inserting your Database-Result-Strings into your Website
You can encode your Database String to HTML by using the HtmlEncode-Function from HttpUtility in .NET
Here is an Example from vb.net
myEncodedString = HttpUtility.HtmlEncode(myString)
If you use "myEncodedString" inside your WebPage you'll get no additional Characters and a valid HTML-Code.
I have a working WiX installer that correctly writes properties to certain INI files, which works fine, but I have a need to generate the name of an INI file on the fly, from the computer name, eg.
MACHINE(xxx).INI
where xxx is my computer name.
I have tried all sorts of combinations of properties and I just can't seem to get it working. Can anyone put me right ?
This is my latest attempt that doesn't work:
<Property Id="MACHINEINI" Value="MACHINE([%COMPUTERNAME]).ini" />
...
<IniFile Id="IniPermissions"
Directory="MYDIR"
Action="addLine"
Name="[MACHINEINI]"
Section="[ComputerName]"
Key="Permissions"
Value="TEST" />
I never see the value of MACHINEINI, as the filename that gets created is actually called
[MACHINEINI]
The value it writes in is correct, so I see the contents as follows:
[xxx] Permissions=TEST
(where xxx is my machine name)
I have tried using [ComputerName], [COMPUTERNAME], [%COMPUTERNAME]
When I build the installer, I get the following error:
C:\Source\blah\BLAH.wxs(50) : warning CNDL1077 : The 'MACHINEINI' Pro
perty contains '[COMPUTERNAME]' in its value which is an illegal
reference to an other property. If this value is a string literal,
not a property reference, pl ease ignore this warning. To set a
property with the value of another property, use a CustomAction with
Property and Value attributes.
The underlying Windows Installer table doesn't support this. Note that the FileName column is of type FileName. Only the Formatted type can take a [PROPERTY].
IniFile Table
You could need a custom action to write temporary records to the IniFile table to transform the file name. The advantage versus using a custom action to literally write the INI file is that rollback would be automatically handled for you.
It's not possible to tell you how to do this exactly since I don't know what language you'd want to use to write the custom action.
A simpler approach (from the installers perspective) would be to transform the [KEY] name inside a single INI instead of writing to different INI files.
