Im trying to use a Settings file that the program opens and reads the info from when it loads BUT when the user chooses a custom color (ex: ff5f67d6) How can i assign the form background color to that color code?
Dim BgColor As Color = ColorTranslator.FromHtml(Settings(0))
Me.BackColor = BgColor
Settings(0) = the color code
that is the code i tried to use that doesn't work
i am trying to make a program that holds info in the settings... it holds it in an array so that you can add to it and take away from it... he is the code i have so far....
So far it is just the adding part but im still haveing some problems...
Public Class Form1
Public Function array_use1(ByVal array_string As String, ByVal number As Integer)
Dim num_holder As Integer = number
[Code].....
im trying to get this done so i can demonstrate how it works to some friends.
And also note that i dont want you to like write out a bunch of code then tell me its the right way...

View 6 RepliesI'm trying to create a program which reads a text file into an array.
[Code]...
But that's just silly so how can I fix this? Lines isn't being assigned a null value it's being assigned the first line of text in the file which has text in it so I'm confused.
I have to make a program that reads a txt file after reading it, show it in a richtext box and in another tab make the average of the grades the input received sort it by the student id and then in the same rtb sort it by the average of their grades, and finally save it on a new text file.
The text file input is something like this
12 3 10.0 6.9 7.3
19 2 6.7 9.3
10 3 4.5 9.3 4.5
[Code]...
As you noticed in the input the first number is the student ID, the second number is the number of tests made by the student, and the other 3 numbers are grades, in the output the first number is the student ID, the second number is the average of the tests, and the other 3 numbers are grades, I don't have a problem opening and saving a text file and neither creating a tab with 2 RTB , my problem is how do I tokenize or read the input line by line, i guess that i need to use the split function but I don't know how to implement it into the program.
I am making a program that reads a file. Csv,and information to a textbox.
After he demand on the Csv file, the same information he writes what is in the same row forward in the same textbox.
A-dos-Francos;39.346246,-9.031105
A-dos-Negros No;39.366089,-9.090929
A-dos-Negros PV;39.366886,-9.131098
[CODE]...
Example: If "A-dos-Francos" is written in the textbox I want that it be replaced by "39.346246,-9.031105"
But in the same textbox.
I want to be able to double click a custom file that contains text and it pulls up my program and adds the text in the richtextbox.
Basicly I created a file extention called .pwt but I can't get it to load the text stored in it on the richtextbox.
I have a hardware which sends out packets containing 17 bytes to the comport in bursts of 3. the little test VB that I have written receives and displays the bytes in a line of 17 bytes long and works fine until it gets to around 170th packet, then it starts to mix up (looks like shifting the data left) the bytes shift mostly by one digit sometimes by two. then it will continue to give almost a packet correct and a packet shifted for about 50 packets. Then it will correct itself for a long while, but then the speed at which it receives drops. All the packets are sent 3 times, and before things go wrong (within the first 170 packets) the packet counter shows that it receives 3 packet each time but after the problem it goes to 2 packet per burst and then to one.
If i close my VB monitoring program say at packet 165 and immediately open it again, it wont go wrong for another 170 packets, this points the finger at VB. I have check my hardware, there is no problem with that.The program reads port - waits for 17 bytes - once 17 has been received it will go and buffer the packet in an array. In fact they are 2 arrays but printing fro either results in the same problem.I have tried whatever i could think of but to no avail, i am wondering if some kind of house keeping needs to be done to clear something... I am sorry the program is a bit messy but I have been making many changes to find out what the problem is - my code below:[code]

View 1 RepliesI need to create an application that reads numbers from a file. it then should display the total of the numbers, display the average of the numbers, display the highest number in the file and display the lowest number in the file. We are using visual basic 2008. I am new to this and stuck . How do I begin. I included the number set that we are supposed to read from.

The code below reads each line from a file and if the conditions become true it adds the contents of the file from the particular line and after into a string collection (i.e. the All contents). This is what at least what the code should do as the current one only adds the line that it encounters into the string collection.

View 5 RepliesI currently have a program that I made which opens other apps packaged with an installer. I have set the installer to install everything to the Program Files folder. However, not all computers have a C: hard drive. I have a way in which they can enter their drive letter in one form then in the next form it remembers the drive and will take them to the program. The problem is my program stores the drive letter in an xml file. On the startup of the program it looks in the xml file to find the drive letter, if there is no drive letter the form opens then lets the user set his drive letter. The xml file is stored in the folder "Math Wizard" in the Program Files folder. But if not all computers have C:Program Files I need a shortcut to the program files folder. I have been trying to use %ProgramFiles% (%Program Files% + "Math Wizardconfig.xml") but vb is saying that the % is an invalid character. Here's my code:

I'm developing the program which opens files/programs that I have selected and checked with checkbox1, 2 and 3(i haven't coded the tihrd one yet, but it doesn't affect). The first program runs instantly and others run after X interval if it's wrote in textbox4 and checked by checkbox4. So Checkbox is like an activator for this interval. If checkbox4 isn't checked then every program should run instantly. The problem is that checkbox4 isn't doing a job. Program activates the interval if there are somekind of numbers in textbox4. It doen't matter that is the checkbox4 checked or not.

1. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...

Regarding 2. - do I need to invoke
Is this all I need? And if so, why are my user.configs empty?
