File I/O And Registry :: Find/Extract String From A Text File?
Jun 7, 2011I've got an application that passes commands to a terminal window and saves all the output to a text file Here is one of the commands my application passes to the terminal

The output of which is
"HostA has address Y.Y.Y.Y"
this along with a whole bunch of other text is saved to a text file...my question is how do I find the sting "HostA has address Y.Y.Y.Y" in that text file and then extract the IP address and assign it as a string variable?
File I/O And Registry :: Random Access File Larger Than Text File?
Jan 7, 2009I am writing a program to calculate Pi to several hundred billion decimal places and this will require lots of GB of memory. I wrote a test program in VB2008 that saved the first 16 digits of Pi (without the decimal point) to both a text file and a random access file, just to be sure it was outputting the numbers properly. For reference the first 16 digits of Pi are:

May 20, 2009So 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.

Extracting Text From Htm File?
Aug 21, 2009I am trying to extract text from an htm file (output.htm) to write into an SQL database.
I used "pdftotxt" to re-write the original pdf document into an htm file, in 'raw' format, and end up with lines like this:
Sun20
Off
0330
0329
[Code]....
What I am trying to do, using the above example, is to look for anywhere in the list where a date(e.g Mon24) is followed by lines containing KL ####, and to extract the date and the KL #### for writting to a database.
It seems like a huge task that is way beyond my limited capabilities, so I would be very grateful for some sample code in VBasic.

File I/O And Registry :: Implement A Routine To Read A Plain Text File?
Mar 21, 2010I need to implement a routine to read a plain text file, BUT that file has a predefined format.The file format is as follows:

<FILE_PROPERTIES> 'The "< >" also appears
Propertie1="String" 'It's possible to have spaces after or before the "="
Propertie2="String"
Propertie3="String"
PropertieN="String"
[code]....
Is there any Windows API Routine to read something like that?Or could you point me an URL where something is implemented?I don't want a procedure to read the file line by line and comparing them with Line Input because blank spaces, empty lines and comments starting with " // " may appear too, and I don't want to take them into account, but also I need to save changes to the file, but only to the modified section, without having to read the whole file, and re-write it completely.
Binary access can't work, because I don't know what's the size of each "section", since the number of elements into it can change.
I need something like the "ReadINI" Windows API Procedure, but allowing me to read the "[XXX]" sections headers, and also the "<XXX>" file title header.

View 2 RepliesFile I/O And Registry :: Creating A Text File, And Using It Among Different Windows Users
May 31, 2009I created an application that when a user logs onto their Windows account, a Form is displayed outlining the current Computer Usage policy set by the insitution and gives the user two options either Agree or Dis-Agree. The two options are in the form of buttons, with events that depending on what the user clicked, will create a log text file at a specified location, with enteries of Date,Time,CurrentUser, and if they agreed or disagreed. If they agreed the application after creating/amending the file will then terminate, otherwise it will update the file and then force Windows to logoff the current user.
Now I made a shortcut of the .exe of the application and placed it in the startup for all users, and yes the application loads at startup for all the users following the procedures mentioned above. The problem I am facing is, that if the current user logs off, or is forced to log off, and another user logs onto Windows, goes through the whole ordeal mentioned above, the application is denied access to the logfile that was created under the previous user, and thus crashes.
So my question is, how can I created a text file using vb 2008 application, that is accessible by multiple Windows users. I have even tried changing the location of the created file to the shared folder, but the end result is the same.
File I/O And Registry :: Deleting Lines In A Sequential Text File?
Mar 22, 2009I know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file
Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin
Code:
"Josek Sam","68 West Land Street","149 Union of States","4524563","45635463","JOSKSAM1",#2009-03-02#,"MILANCGLZ2008"

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..

2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above).Include suitable headings. Note that you cannot assume that the file contains onlyresults for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.
The output might look as follows:

Extracting Text From Emf In A .pptx File?
Dec 22, 2009I am trying to extract text from a .pptx file. I am able to extract from all other shapes except a shape that is identified as a msoPicture to right click on this shape in powerpoint and ungroup it, but when I try to do this from code it tell me that the ungroup method only applied to group shapes.I did some research and found out that the msopicture shape comes from a .emf file but I don't have the least idea how to ungroup this shape or get the text from it through code.NB: When I right click on the shape in powerpoint and select ungroup a message box pops up saying "This is an imported picture, not a group. Do you want to convert it to a Microsoft Office drawing object?". But I cannot seem to find a way in code to convert this shape to Ms Office drawing object.

Mar 17, 2009I have a variable (double) that is constantly update in real time with data from an analog input. I would like to write this data as it comes in to a txt file. When I stop my acquisition of data from my analog input, I should have a txt file with all that data stored on my computer wherever I want it. The way I'd like that txt file to be laid out is like so:
Test Title: "This info comes from a string variable"
Operator Name: "This info comes from another string variable"
Test Date: "This info comes from yet another string variable"
[code].....
And so forth. As you can see I would also like to write the time for each data. This depends on my Timer interval which the user can set. The default is 50ms. So by default, y1 y2 y3 would be 0, 50, 100. How would I generate such a text file?
