IDE :: MS Access Table - Exporting Data In Fixed Width Format
May 23, 2007
I am using ms-access 2002. I have to export the data of a ms-access table in Fixed Width format. To accomplish this I am using DoCmd.TransferText method.
DoCmd.TransferText acExportFixed, "schema.ini", "table_ABC", "C: estingTestData.txt"
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
DoCmd.TransferText acExportFixed, "C: estingschema.ini", "table_ABC", C: estingTestData.txt"
but no success.
For delimited format it is working fine
DoCmd.TransferText acExportDelim, "", "VDMMEMBS", "C: estingTestData.txt"
I have gone through the link [URL]
Error message is same as of me but example shown is related to import of txt file.

I 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.

I 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.

In Excel under Data Tab-Text to Columns-Fixed Width- and when next is pressed we get preview of Selected Data.
There a Scale is being designed(10, 20, ...). Is there any way in VB.net to do that scale or any other form of Implementation.

I am learning to use TextFieldParser to read a fixed width text data file. It works great. I copied code below. Question: How to stop at the end of each line because I need to add some code?
Using tf As New TextFieldParser(fileName)
tf.TextFieldType = FileIO.FieldType.FixedWidth
tf.SetFieldWidths(60, 30, 20) //three columns

I have an access database (made by other application) that I need to read it. The problem I have is that the tables I need to read do not have the read permission; the access permission is set to "Share Deny Write"; though I can open the database in MS Access and export the table to another mdb where I can read it. Is there any way to automate this, or to set read permission on the database using VB.net? Is there any other way to get the info from table not having the read permission?

What I need to get done here is not a GUI, like the SQL Import and Export Wizard, which can be run from the SQL (2000) Enterprise Manager only, but a code that I can run from within the Visual Basic For Applications IDE from Microsoft Excel 2003, maybe in the form of a module, class or userform or a combination of all three. The best that I have come across so far, was a class that first checks if the worksheet is in a database formattable condition, then creates the database, if it does not exist, a table and then transfers the data from the worksheet to the table.
I have tried the Access 2003 TransferSpreadsheet method, but that does not solve my purpose, because I want to move the data from Excel to Access, starting from the creation of the database itself.

I 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.

I 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

I'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)

I am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?

I want to set header column width for grid view. I tried HeaderStyle-Width="30px". But it is depending on Item columns. The column width is setting based on item value. But I want fixed width even if it has value or empty.

I 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.

What I'm looking for is a snippet on how to export data from a datagridview to an access DB. My other question is fairly simple what code would I use once the data has been entered to account for the addition/subtraction. I know these are fairly
simple questions with probably incredibly easy answers, but once again the first time I've picked up a programing language was a week ago. Hey trial by fire works 70% of the time all the time.

I am trying to export cells in a DGV that has time formatting. The data for the cells is stored in an Access database that also is set for date and time. My problem is when I export the DGV to excel, the date and time show up as pound symbols until i click on the cell, and it adds the current date with the time even though in the app I only put in the time. All I want is the time to show up in the Excel cells and not to have it show up as pound signs.
