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 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.
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.
View 1 RepliesI 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 have an integer array which contains the different col widths for an range of excel worksheet.when i use Range.ColumnWidth= ColWidths (Colwidths is the int array), it takes lot of time to do all the process (i.e opening excel , formatting range, setting values)But when i use Range.ColumnWidth = 15 then all the process is done in a flash.Why using an integer array takes time? I did even try replacing int array with string array, but same time taking result?

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:

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.

I found away to read a fixed position text file, but I encounter a problem, I know which field I want to go and check, how can I jump directly to the field I need. Readfields does not helps.for instance I need to check on field 3 and 7 of the row before the next row is read.[code]is this my best approach to read a fixed position text file?
View 1 RepliesI 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.
View 2 RepliesI 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.
Is there a simple way (without measuring characters using a Graphics object) to check if a font is fixed-width?

I am having a problem regarding to Importing file from excel to listview. Actually my problem is that my program will let the user define what database he/she want. I know already how to load on my listview from .txt, access, ms sqlserver, but my problem is the user want to open from excel file. Base from his data, the columns contained Contact, address, age,name and only in sheet1. My problem now is that the user want to call his/her excel act like a database. The tablename will be Sheet1 and if he/she want to display the age and name column he/she can view by calling the its columnname. The columname will act as a fieldname. How can I do this upon loading all of this to listview. I have here an example on how i load data from .txt(csv) format but i need an excel on how to load data coming from excel.[code]...

I am using DataGrid control in VB. I have created a DataTable at runtime and added 5 columns in this Datatable. I binded the data table with DataGrid control.
Width of DataGrid is 880. The default width of 5 columns of data table in DataGrid is 100. So for 5 columns width used = 500. So an empty space of 380 left at the right hand cornor of DataGrid. I want to fill this empty space with these 5 columns. I want to increase the width of columns so that it fully covered in DataGrid.
I set the width for my ListView columns in the designer, in run time they always shrink back. I have no idea why, could anyone shed some light on this for me - possibly a solution to keeping them exactly the way I set them in designer ?
