Fixed Width File EXPORT: VB
May 6, 2009I am aware that this is a visual basic dot net post. However It was extremely simple for me to write out a file in VB6 using lines such as the following snippet
[Code]...
I want basically to export an array A (I used zero based array here) with three columns and a particular value B in fixed widths, hence the @@@@@ which means 5 spaces in to a text file defined by the FreeFNum (FreeFileNumber).
I would like to use CSV and all the other formats but some scientific programs written in FORTRAN may not support them. Anyway my file output here needs to be in this fixed width format because it will be used by proprietary software that I have no access to the source code.

Fixed Width String Parsing?
Aug 5, 2011I have files that are one long line of text but are made up of individual segments. I have managed to parse the segments into a string array but now need to parse each segment into its individual fields, based upon a field structure defined by the first 2 characters of the segment.For example:
CA12345ABC999999XXPPPPPPPP55
CA segment (CA is first 2 characters of segment) has fields defined as:
Field Name,Start,Length

Read Fixed Width Txt File?
Jun 18, 2010I'm using vb6 to read lines of txt files, using the code posted in ream.In.Code "Reading a Text file Line by Line". My question is how can I real a line with fixed column width, for example:
qwerty 12345 asdfg
asd 455 hfgdf
qhjkrty 1235 asdfg
The objective is to read each part of the row. In Visual Studio 2010 Beta version the code I present below that is actually working but it doesn't work in VB6.
Using Reader As New Microsoft.VisualBasic.FileIO.TextFieldParser("C:\teste.txt")Reader.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.FixedWidthReader.SetFieldWidths(8, 30, 25, 45, 57)

View 2 RepliesDisplaying Fixed Width Text In WinForms?
Jun 22, 2011I need to write some fixed-width font (i.e Courier New or Consolas) text to a .net Winforms window in the Paint event - not using a label or any other winforms control - rather using a graphics object method to render the text onto the form's client area. I am having difficulty aligning text on different lines under headings even though it is fixed width font. How can I get a precise measurement of the width of a single character in the fixed-width font? How can I get 2 lines to print out aligned horizontally in successive text out calls?
For example:
Heading 1 Heading 2
Short Other text
A bit longer Still aligned?
I need a separate call to render each cell of text under Heading 2. For argument's sake - let's say column 1 items are printed in black and column 2 are printed in blue - we can't use the same text out call for the entire line.
Format A String Into A Fixed Width Field In .Net?
Aug 1, 2011I am trying to format a string of arbitrary length into a fixed width field for display.
Let's use a width of 20 as an example, and call the string to be formatted s. I'm adding the formatted string to a StringBuilder named b.
Dim b As New System.Text.StringBuilder()
Dim s as New String
If the string I want to display is shorter than 20 characters, I can do this:
b.Append(s.PadRight(20))
or
b.AppendFormat("{0,-20}", s)
So far, so good. But, if the string is longer than 20 characters, I want the string to be truncated to 20 characters as it is appended. The code above appends the entire string.
I tried this:
b.Append(s.Substring(0,20).PadRight(20))
But, this fires an exception if the string was shorter than 20 characters.
So, I ended up with:
b.Append(s.PadRight(20).Substring(0,20))
This seems to do the job. The PadRight prevents the exception by making sure thet string has 20 characters before the Substring is performed.
I was wondering if there is an alternate method that would look more elegant and avoid padding the string just so prevent the substring from causing an exception. Have I missed a feature of String.Format that can accomplish this in one step?
Edited to add solution:
I ended up with the following code:
Module Extensions
<Extension()> _
Function AppendFixed(ByVal b As StringBuilder, ByVal s As String, ByVal width As Integer) As StringBuilder
[Code]....
This uses an extension method to clean up the syntax, as suggested by Joel and Merlyn, and uses the StringBulider Append overloads to avoid creating new strings that will have to be garbage collected, as suggested by supercat.

But I am getting error message: "Run time error-3625 The text file specification 'schema.ini' does not exist.You cannot import, export, or link using the specification."
Here schema.ini is at same location as of text file. i.e. "C: esting"
I tried with

but no success.
For delimited format it is working fine

I have gone through the link [URL]
Error message is same as of me but example shown is related to import of txt file.
Import Fixed Width Text File Into Access2007 Table
May 7, 2011I am trying to load a text file into an Access 2007 table. I know you can read the file line by line and then create a record out of each line. i was trying to see if this could be done with an INSERT INTO rather than cyclying through all lines of text. My text file is not character delimited but rather by fixed column width. For example:[code]The data in the example has spaces for readability but in reality the data are clumped together like so [code]I cant figure out how to tell the command how the data is structured. I know you can use a schema file but there's got to be a way to do this all through code.

Get Font Width Without Measuring A Control?
Aug 2, 2010I need to display a table in rich text within a form window. It is only a two column table, so tabbing works fine to line everything up (since RichTextBox does not support RTF tables). However, sometimes the tab stops are incorrect because of non-fixed width fonts.
So, I need a way to measure the pixel width of a particular string with a particular font (Arial 10) and space or tab pad to make sure that everything aligns.
I know about the Graphics.MeaureString method, but since this is in a rich text box, I don't have an initilzed PaintEventArgs variable, and that would seem like overkill to create JUST to measure one string.
From MSDN:
Private Sub MeasureStringMin(ByVal e As PaintEventArgs)
' Set up string.
Dim measureString As String = "Measure String"
[Code].....
So is the best bet just to create a dummy PaintEventArgs instance? If so, what is the best way to do that (since I'll have to call this string measuring method several hundred times)?

View 4 RepliesIs SubReport's Implicit KeepTogether Feature Fixed In VB 2010
Sep 22, 2010This behavior occurs because the Subreport control has an implicit KeepTogether property. By design, the KeepTogether property tries to keep content of a subreport on one page. Because of this behavior, the report engine creates blank space on the main report if the subreport does not fit on the same page as the main report. Then, the report engine creates the subreport on a new page.
