Code Opens A File In Example 1 And Writes On Another File Only The Lines?
Jan 16, 2010
The code below opens a file in Example 1 and writes on another file only the lines that satisfy the condition If times > 4 to another file. What I want to do is illustrated in example 2
[code]...
t= 2 comes from Subtracting t= 11 - t= 9 from the script in example 1. I have scripts with thousands of lines every time the program should automatically subtract the next value with the previous one and write the result into a new file starting from t= 0

I've had a search through a number of extremely useful articles on the forums, however rather than reinvent the wheel I thought I would ask if anyone already had what I am looking for..A simply little VB app that opens a session to a specific IP port and then writes to a test file everything it receives. If the connection drops, simply re-stablish it and keep listening for text to write to the file.

how can I let VB.Net writes an excel 2007 file? For example, the data in a TextBox will be written to the excel file every 30 seconds.The enviroment is VS2008, .Net 3.5.I've just started VB for one month, so please give me a piece of code to help me understand. I tried to find the solution on the Internet, but none of the codes worked for me, some people mentioned import "Microsoft.Office.Interop" in the code, but if do that in my code, VS said that "Namespace or type in the Imports 'Microsoft.Office.Interop' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file
Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin
Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"
"Josef Malm","142 Unions Street","64 Hamersters Street","452504","42542054","JOSFMALM2",#2009-03-06#,"MILANCGLZ2008"
"Dave Green","131 Oxford Street","96 BlueBane Route","452542452","43254345","DAVGRN3",#2009-03-07#,"MILANCGLZ2008"
I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..

what im trying to do and what i have done so far is probably a little backwards not sure sure how to id it any other way.when the user generates an error because a particular file doenst exist ive got my dialoge box to generate an .txt file for each file it errors on, so that the administrator can check and update missing files as an when - shouldnt be many files missing in the first place, should just be new product ranges or item just launched.what im stuck on is:
1. is there a better way
2. how do i open a .txt file and add the extra lines to it, so i re use the file but keeping the previous data.

Basically I am saving text to 2 seperate ini files, also saving the checkbox.checked value so my form can skip the login and auto start. My only problem is when a user saves the information to the INI files after writing them they automatically open up the INI files for display. When the form loads it automatically fills in the fields and if the checkbox is active it checks all the correct details then starts, only problem is it loads the checkbox1.checked ini file then starts the main menu. How can I skip this? and make it not show the ini files everytime they are called upon?

When i try to do this it only opens a bunch of tabs? and lastly how do I make it so that when it installs on a computer it installs straight to the start-up folder without the user knowing it, or how do you make it so it opens automatically on start-up?

Here's what I'm attempting: The user browses for and opens a dbf file. The user is presented with a checkedlistbox which shows the column headers. The user then selects the columns they wish to run a report on. ex. total # of cells not empty, longest cell length, etc.
I'm to the point of populating the checkedlistbox with all of the columns shown but I'm unsure if the users selections are actually linked to my data and if they are how I go about isolating said selections for the reports. I have a feeling that my approach to populating the checkedlistbox is not the proper way for what I'm trying to accomplish.
Here is the code
