I know how to change all of the .Substring's in the text file to the .Item's from the DB.

Create Log File To Track Progress And Populate Controls Via Text File Or XML File?

May 22, 2009

I 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

File I/O And Registry :: Random Access File Larger Than Text File?

For reference the first 16 digits of Pi are:

Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:

Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0

File I/O And Registry :: Opening A Text File Into Multiple Text Boxes Using Loops And Arrays

May 20, 2009

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:

Quote:

SHOWNAME
CALLNAME
BREED

[Code]....

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.

Remove Character From A Text File And Prevent Crash W/ No Text File?

All I would like to do is remove one character from the line of the text file that I am reading, which is the first character and also prevent the program from crashing if no text file is present.Here is the code. Can anyone notice where I am going wrong? I thought the "if" statement would cover the crash but it didn't. Clueless, but sort of have an idea on the character removal.

Scan A Text File To Determine If It Is A Text File And If It Contains Any Non-ASCII Characters?

Jan 27, 2012

what would be the optimum code in VB2010 that check a file to determine:

1) is it a text file, and

2) if it is a text file, does it contain any non-ASCII characters

Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.

Converting .exe File To Run On Mac?

Nov 14, 2010

I made a program a couple of months ago and decided to put it up for sale for a minimal about of basicly just to cover costs. Seems word got round and people from all sorts of places are asking if I can modify program and add features which I have done and was happy to do. I have around 57 requests in my E-Mail at the moment asking me to make a Mac version and from what I can tell, all the proccess involves is converting the .exe file to a file which can be run on the mac. Before someone offering there good faith to test it for me. I'm sorry but that won't be an option for me.Would like to run a Virtual Machine, but that would be against copy right laws.

Create And Write To A New Text File From An Existing Text File?

Sep 2, 2009

I have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.
