VS 2008 Make A Program That Reads A Txt File After Reading It?
Aug 26, 2009
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 would like to create an application that can browse the DLL file and use the codes inside it. Not by adding it as a reference, or something. Just browsing the DLL file to use the codes inside it.
I am trying to write a basic .net program that reads from one file with streamreader, scans each line for specific errors in formating and if the errors exist correct them in an output to another file that I've just renamed as same file name.cache.
I'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.
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
Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain Dim intCounter As Integer 'Stores the # of commas in the string Dim Messages(49) As MessageProperties
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]
1)How can I make my program get the contents of a .txt file on my website to tell the program to run or not?Here is and example of what I want:Say the file says "Running", the program would run without problems.If the file was to say "Unavailable", a pop up would appear saying "The program is currently unavailable, try again later." Then once the person clicked OK, the program would close.
2)How can I make the program get contents from a .txt file to get the latest version of the program, then if there is a newer version, there would be a pop up saying there is a newer version and they need to update. Then when they clicked OK, the program would close and it would open their default web browser or Internet Explorer to the update page.

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.

I have the following code, which reads data from xml file and displays it in the datagridview. It all works fine:
[Code]...
Instead of showing read data in datagridview, i'd want to read the data from xml file into one dimensional array: X(Impedances) Or is there a way to read value from this datatable into string variable without getting data from datagridview? The point is: i'd want to scan through all "Impedance" values (which are read from xml file) and compare with value y to catch the nearest value to y. How to do that?
I'm currently finishing up a project that reads / writes to an access database. The only issue I'm having is that it needs to have the file path to the database file. EX:
What I do is I have a variable on form1 and its an integer which has a value on load of 0 and named count.When I click the 'doSomething' button it is increased by 1 and when I use the function 'msgBox' I get to see 1.After that I start a thread which is going to look up count but when I check the value there is 0.
Is there a way to rotate a label such that it reads vertically? I've checked all of the label properties but there doesn't seem to be one that will do the trick.
