sir, i have no idea how the code will look, but i want it to assign a value after reading from a text file and then store it for further use even if the text file is not there, but without using any external storage like registry, disk, ram. It should store the value in itself and do like this:-

I am binding a textbox's text value setting to my a variable in my configuration file. I only consider the input from this textbox to be valid if it's an integer number bigger than 1. Right now what I was doing is letting the user write whatever he wanted in the box, and I'd only let him save the settings after calling a validation function. The problem seems to be that my binding variable in the Settings class seems to be being updated as soon as the textbox is being edited, and that's a behaviour i'd like to skip. How can I do this?
View 3 RepliesCurrently, I've encountered a problem where I do not how I can store the variable of my battery level in a text file. I tried .xml and .txt file and it returns me text which can't be read.The code related:
vb.net
[code]Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent
[code]....
The place where I do not know what to insert is the "Insert Battery Percentage Here" part so I guess that's the problem.For your info, if you were to use a MsgBox to display, the code which displays that would be <MsgBox("Total battery power remaining: " & perFull * 100 & "%")>

View 14 RepliesI am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:

So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.

View 1 RepliesI'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.
