Reading A Specific Line From A Text File And Displaying It In Individual Text Boxes?
Feb 16, 2010I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.

VS 2008 Displaying 2 Values From A Single Combo Box

Jul 23, 2010I have a text file called: list.txt This is a list with all kind of lines like this:
14II_ARM_S_CLO_CLO_CLOVERIDS_PROPITEM_TXT_01194611IK1_ARMORIK2_CLOTHIK3_CLOAK=TRUE==200050000====PARTS_CLOAK=1==11=1===11_NONE Ofcourse every line has different numbers and letters.
The complicated bit is this:
I want to let Button1 check whats in TextBox1.Text and search "list.txt" for it. When it has got a match (there is only ONE of these numbers in list.txt).For example TextBox1.Text = "IDS_PROPITEM_TXT_011946". And I search for that so I find the line above. Now I want 3 other textboxes which show the 21st, 22nd, 23rd column/number after "IDS_PROPITEM_TXT_011946". And they should be editable by changing those 3 textboxes and clicking the apply button.How can I best do this, and please give a little example.

[2008] Reading A Very Large Text File
Feb 1, 2009The following code suppose to:
1. Read line-by-line a txt file with more than 500,000 lines, (each line 521 characters long)
2. extract an ID No from the line
3. query from a database for LCCIStatus
4. concatenate the value of LCCIStatus to the line
5. write the line to sample.txt
My problem is, this code works perfectly with the test file of 8000 lines but fail with the actual files which have over 500,000 lines. FYI, the test file contains data which I cut and paste from the actual file.

Description] "Every hundred years, the dark vampire known as Dracula resurrects and terrorizes the land. A vampire hunter named Simon Belmont bravely ventures into the Count's mansion in order to defeat him. Along the way he'll have to defeat skeletons, bats, fishmen, medusa heads and other evil creatures.Castlevania is a side-scrolling platform action game. The player taking the role of Simon Belmont is able to jump and crack his whip directly in front of him. Power-ups can be obtained by defeating enemies or by whipping candles that appear in the castle. One such power-up increases the power and length of Simon's whip. Different weapons can be gathered which consume hearts when used, these hearts can also be collected from monsters and candles. Additionally, some walls will hide secrets such as the health-restorative turkey or the Double and Triple shot abilities for the weapons Simon has collected. At the end of each section of the castle is a boss, which must be defeated. Progression through the castle eventually leads to a confrontation with Count Dracula himself."

When you first open the program it gives you a form with either a list box or combo box (not sure which one I want to use yet) and then an add button to add a name to the list. It shows the from where you enter a name and then when you add a name it adds it to a text file that I have saved onto the desktop. It keeps the names on separate lines and I want each line in the text file to be an item in a list box...
