How can I parse a text file and extract the data to excel file. The text file is in the following format

My application is supposed to parse a text file (relatively easy) and create an excel spreadsheet report. Should I write a stand alone VB.NET application that saves the excel file, or should I use VSTO? I am unsure if there are any differences in terms of ease of development, usability issues, API functions available, etc.Are there any other programming languages/interfaces/libraries that will allow me to rapidly develop an involved excel spreadsheet? I am talking about things like functions, graphs, etc.
View 3 RepliesI need to parse some text to extract the name/path of an image file inside an X file. The part of the file looks something like this:
TextureFilename {
"C:\\Users\\USER\\Documents\\Map\\Textures\\Grass01.dds";
}

# TAG NAME = is saved to a file using the code below but when I load that same file back into a RichTextbox Control using additional code below, I get inconsistent results as I try to parse the text. Has anyone else had this problem?'Save the contents of the RichTextBox into the file.richTextBox.SaveFile(saveFile1.FileName, RichTextBoxStreamType.RichText);'Retrieve contents of File into RichTextBox control Dim logData As String
logData = System.IO.File.ReadAllText(path + "\" + filenname);
I would like to know how to remove part of a text file between two points
For example, say i have a text file that contains:
Code:
START
<LOWER_LINE>
-4.920156 -2.543200 4.277774

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
View 1 RepliesI have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls
is showing missing records at the end of the file , so i save my file as an .xlsx extension it saves correctly but when i open the file it generates an error
"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."but when i test the file i drag it and open it in an empty notepad all the records shows up correctly
in my text file i have two part. Called bottom and top. So i need to read the Top part first then and match the line with bottom part. Its like this

I have an app that the user selects information and it writes to an XML file. The user can increase and decrease the information in the XML file so it is dynamic. The other app reads the xml file and uses it to complete tasks. Since the XML is dynamic my code needs to account for that. Right now I have only allowed the XML to have up to four values in a certain node, I would like to allow more but I will need to increase the Select Case function.[code]

I'm working with vb.net 2008. My application generates 1 excel file (with login details etc). The application will store user results for various sections into csv files. I'm trying to combine the csv files into the excel file. I'm trying to get this to work with one csv file initially ...but I am ending up with a blank Excel file. This is what I've tried so far:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim oExcel As Object

I occasionally have to search a very large text file as a troubleshooting step. The file is continuous text (with spaces between much of the text) but almost everything is date/time stamped. The text is actually messages between two machines so I'd like to insert a line break after every message so that I can follow the protocol exchange. Thre are also a few key words that I'd like to again, separate with a line break.

I'm working on a project and am kind of new to parsing files as well as listviews. I am trying to parse a file. Here is an example of what I need to parse.
a:b:c:d:e:f:g
a:b:c:d:e:f:g
a:b:c:d:e:f:g
Each entity needs to be stored in it's respective column in the listview. So therefore I need to read the file in line by line.
So, I'm writing an application to extract data from an excel sheet and output it nicely in a text boss, sounds simple to me at least. But for some reason ( and it was working fine earlier, don't recall changing anything.) The file is not being parsed before being stored into the array. And since it's not parsed, it's not seeing it in the array as I don't have it set up to look for a substring.[code]...

View 1 RepliesI am using VB.NET 2005 (if that matters).I need to parse a text (log) file in which to process lines like:
Program Up at: Tue Jun 24 11:32:53.656 2008 - TerrificProgram.exe
<some lines here which I ignore>
0.00:24:16 - Emergency Stop!
<more lines to ignore>
Program Down at: Thu May 29 22:22:56.000 2008
where the 0.0:24:16 is the offset in TimeSpan format (d.hh:mm:ss) relative to the 'Program Up at" datetime.The 'Program Up at: <date/time>' line I successfully detect (in another function which works) and as a result a set a Boolean flag that I am in a valid <Up> - <Down> sequence and I also set a Start-up DateTime var to which to add the offsets later.
The task is to convert the TimeSpan at the beginning of the 'Emergency stop' line to a regular DateTime expression and to write the converted line to another log-file.Simple, isn't it?The function I use for the above purpose is:
Private Function IsTimeSpan(ByRef InputLine As String, ByVal ProgStart As Boolean, ByVal DTofProgStart As DateTime, ByRef NewDateTime As DateTime)
Dim iLine As String = InputLine
Dim Index As Integer = iLine.IndexOf(" ")
[code]....
What I am doing is I pass each line ('InputLine' parameter) from the original log-file to the function together with the 'in <up>-<down>' flag ('ProgStart' parameter'), the start ot program DateTime (in the 'DTofProgStart') and I want the NewDate to hold the real datetime of Emergency event occurence (not its offset).
What happens is that I successfully detect the lines of interest but the NewDateTime is not updated (though 'ts' is in the correct format and the assignment 'NewDateTime = DTofProgStart' correctly assigns the passed value).Another curious thing is that the line
InputLine.Replace(testStr, NewDateTime.ToString("MMM dd HH':'mm':'ss yyyy"))
does not change the original TimeSpan beginning of 'InputLine' with the regular DateTime (though not updated) in 'NewDateTime'.Why?
