I got an text file that record data, and I need to read the data and do some comparisons. All data read will be showed in a form. If the data is fail, I need to show an alert to the user and wait for user to respond. If user responded to the alert, the program will continue to read data and do comparisons. The issue that I'm facing is that I don't know how to continue read file from the last read point.
View 19 RepliesI'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.
T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

View 2 RepliesI'm not really sure how to word it, if it is possible, but part of my program reads from a text file. It then pulls out the necessary information needed from that file by finding key identifiers. Right now the code is written to find the first key identifier and then read each line after that, locating each subsequent identifier and pulling the data from it. In a few cases, the format examples I've worked with are a bit different which results in a runtime error. How can I tell the program to essentially skip that part of the text file if it's not reading it right and continue moving on? Here is somewhat of an example of the text file.
DID/"DATA EXTRACTED HERE"
NAM/"DATA EXTRACTED HERE"
STR/"DATA EXTRACTED HERE"

View 5 RepliesI'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

View 2 RepliesWhen I do the try/catch method in my vb.net project I will try the code I want and when it can't do it, i make a message box right after the catch method. The thing is that it will show the message box, and then another message from the program itself. Like for example, I have here a MySQLException, and when i click ok on the message box, it will show another one right after showing the exception itself. How would I be able to get rid of this so the user doesn't have to see this, and the program can continue.
