I'm working on a program that when you click a button called new it pops up a new form asking for you to enter a directory location. If the directory exists it saves it into this file:
"C:WindowsSettingsButtonVariableSaves.ini"
I already have working code that saves each directory entered into the ini file on its own line.
Now in this code I'm trying to call each variable back from the ini file when form1_loads and set it to an array called ary() so later I can set the first 10 saved within the array.
So later:
button1.text = ary(1)
button2.text = ary(2)
and so on to
button10.text = ary(10)
and the reason I set the array to record all lines even if theres more than 10 because I want to be able to add more buttons later on.
Here's my current code for saving lines to an array:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim FILE_NAME As String = "C:WindowsSettingsButtonVariableSaves.ini"

On my form, I have a picture box that starts off blank, but draws lines according to mouse click events.
I am now trying to test whether there is colour in individual pixels, yet I am yet to find solid code.
My initial code was along the lines of
Dim bitm as bitmap
bitm = PictureBox1.Image
This would come up with nothing, as there wasn't any image assigned to the picture box.
I was wondering how I could save the lines drawn and use that as a bitmap to test pixel colour.
I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..

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'm using the Chilkat add-on to read email from a pop3 server. I can download the headers fine but the headers all download into one column.How can I get my email to put the headers in the appropriate columns?

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.
View 16 RepliesI created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

View 3 RepliesI have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.

I need to be able to open a selected file (upon the user selecting it from his/her computer) in different browsers (CHROME, FIREFOX etc) I have downloaded the portable versions and placed and have figured out how to get them to open, but am not sure how to open the file selected in each seperate browser. is it possible to dictate the position and size of each window that opens? Because preferably I would like to be able to divide the screen up with each of the browsers selected.

I am reading a text file in which has three colums of information i.e.
00100 25690 21586
23510 25694 24856
25896 45478 52897
58745 59687 12364
I want to read the whole file, and split the colums so each set of numbers is put into an array to be used as an input for later. If the text file only contains one line of numbers like 00100 25690 21586, I have written a code to seperate those and put them into an array which is attached. If the text file contains more than one row of numbers I can read the whole file in line by line but I can't get the strings seperated.

I have been trying to find out how to do this for days now, so I am finally asking how. I am newish to programming. Here is my problem.
I am trying to extract x,y,z coordinates from a text file arranged as such:
x,y,z
x,y,z
x,y,z
etc.
I need to be able to extract the x column into an array, the y into an array, and the z into an array. I learned how to pull it into a string, and how to split for every line, but i don't know how to split after each comma and separate them.
