Import Numeric Data And Export It To Various Text Files Using Ascii Templates?
Feb 27, 2009
I am developing an app that will import numeric data and export it to various text files using ascii templates. I am basically converting the template file into a single string, replacing application fields in the string with {0}, {1}, etc... and adding the result into an array that is then passed to the String.Format(str_Template, Params()) to provide the final output. I have set it up so the template will use the standard VB.Net formatting syntax.
A simple template example:
{<prt_Mark>:G} {<prt_Qty>:F2} {<prt_Length>:F2} {<prt_Remarks>:G}
[code].....

I have been facing a problem since last two days, actually i want to import some data from a file (file can be csv, txt, sql, xls etc) and after some filtration, export it into csv file. Basically i want to know whether a tool which provides an environment to import different types of file or data where we can perform filtration of data with the help of sql query and then data could be save into file(file can be csv, txt, sql, xls etc).

I am developing an application in which data will be handled offline and then fed back into the main application. Hence need the facility of Export & Import of data.I am using WriteXML to export desired data from the server database using dataset.
The data is imported back, into the Client module. During the day client may modify/insert records in the imported data. At the end of day, the client exports back the modified data and which needs to be imported back into the system's main database.Now what I want is, if new record is entered by the client then it should be inserted into the dataSet and if original record is modified during offline mode then the Original data should be updated with the new value. I think, its similar to the DataSet and Database concept i.e when dataSet is updated. But am not able to do this.
At present, if I import then all data is imported irrespective of whether the data already exist or not.And if I implement Primary Key in the dataset then for modified data it gets stuck with constraint.

I have created an application that can store employees details, that part is not a problem and frankly is sorted, I have used a sql database to save my data, all information is displayed in TextBox controls on my main form.
The part I am struggling with is creating 2 buttons.
The first button I want to be able to import data from an excel file into my data set
The second button I want to create is a back-up button, which exports all the data from my dataset into an excel file

I have several DataGridView controls populated with data. I want the ability to export all the data from these populated controls to 1 XML file. In effect the controls are populated after my project runs. The user will be given the option to export the data.
I then in turn want the ability to import this same data back to these empty controls at a later point in time. I would run my project in a different mode which would display the empty controls. The user would be given the ability to uploaded the XML file and repopulate the controls.

With regard to RichText, obviously information is contained somehow with regard to the text colour, font, size as so on and as it supports more than the ASCII character set such as Unicode characters and so on.
Now I know that Microsoft Word .doc and .docx files contain such information.
My question: How to extract just the rich text information only and ignore all the formatting
information such as bold, underline, italic and so on. How can this be achieved with VB.Net
What I am thinking of here, is, imagine a CSV ( comma separated value ) file but in Rich Text Format.
In relation to this, does Notepad only support a limited character set, i.e. ASCII only?

My application is often used to import volumes of data. The application currently supports .CSV, .XML, and XLS. The question relates to handling EXCEL files. Specifically, what are the best practices for coding?
Today, since customers are beginning to see .XLSX files coming in, I modified the code to use either JET.OLEDB.4.0 or .ACE.OLEDB.12.0 depending on whether it was reading an .XLS or an .XLSX. My instincts tell me that cannot be the correct way to go about this. First, customers still using Office 2003 are going to have to download the AccessDatabaseEngine in order to read the .XLSX files. Second, what if a customer installs Office 2010? Are they going to have the 12.0 stuff or am I now faced with another issue.

I am using visual basic 2008 and trying to create an application to plot data from text files. I have several data files of various sizes. They have an unknown number of rows and either 2 or 4 columns.I need to put the data into 2 dimensional array, so value(,) becomes either value(lines,3) or value(lines,1) depending on the number of columns.My program needs to be able to count how many columns there are, and redim value(,) appropriately.I have written a piece of code to count the number of lines (rows) in the file using 'While not (EOF(1)) ....' but I'm stuck on how to count the number of columns.I could ask the user to indicate how many columns there are before the file is read, but I would prefer the program to detect the number automatically.

I only want to place the numerical data in an array. At the moment I have the following code to do this. [Code]. This code places the numbers in the data array when there is not any text in the file, i.e. when there are no headers. I would like to place the headers in another array, and then have the numbers in the array as in the code above.

I'm working on a program for a side business I run with a friend, who is a non-programmer.I've done a program before, using IO.StreamReader and IO.StreamWriter to read and write lines to a text file.
But now, I'm working on reading text data (it's output from an old legacy program) that reads a first and last name, and the customer number (6 digits) from one file.
Then, it uses the data (customer number) read the first time to cross reference the zip code and status from a second file, and display it.
The Data in the Text Files are as follows:[code...]
How would I begin parsing for the first and last name, and the customer number to assign to different variables?In the line that references names.txt I meant to put customers.txt.
That's a snippet of code I took from a previous program, so I know how to read the data, just don't know how to extract it.

I am using data grid view in Vb.net and would like to load two excel files into it. My two excel files look like this:
[Code]...
The problem I want to solve is the following:I would like to map the values from the data set in file 2 to the sorted data set from file 1. So for example If I want to sort all the data by id# descending then (using the example from above) the data in datagrid view1 and in datagridview2 should be reversed.
Right now if I sort the column from file1 in datagrid view all the other columns in THIS datagridview1 are also sorted in relation to column2. What I want is that the columns in file2 will also sort according to file1.

I am writing a Windows service to import data from CSV files dropped into a directory. One of the steps is to load an XML file with validation rules which I load into a List(Of T). It will pull the data, and then I have it pass the list to a class that monitors the folder and processes the files. After that I clear the list and read in the next file configuration. Now I have noticed that the validation rules aren't matching up and it seems that the list is being passed as a reference type even though the signature is of a value type.Is there anything I can do to get around this?
[Code]...
So here when I pass it, at first it will have 3 validation rules in the new ImportService class I created, but when I call fields.Clear(), it wipes out the class member of the ImportService class.
