Converting Quick BASIC To VB - Random Access Files

Jan 16, 2012

I'm trying to convert an old Quick BASIC program to VB.Net. There doesn't appear to be any direct replacement for the old file statements. Building a database seems like overkill for my simple needs.

How can I do the following in VB.Net?

OPEN "test.dat" FOR RANDOM AS #1 LEN = 20
FIELD #1, 10 AS a$, 10 AS b$
LSET a$ = "One"
LSET b$ = "Two"
PUT #1, 1
GET #1, 1
PRINT a$, b$


Converting VB5 To VB2010 - Random Access Files?

Jul 27, 2011

I am trying to convert a VB5 program to VB2010 so that I can continue to support it on my new PC. My copy of VB5 was an upgrade from VB3 which was an upgrade from VB2 which came on floppies, so I can't just install every preceding version as my new PC doesn't have a floppy drive.I have accepted that I will have to design all the forms from scratch (whatever happened to twips?) and will have to go through the thousands of lines of code line-by-line, but I have hit a brick wall when it comes to random access files. One such file is defined in the Declarations section of Module1 thus:[code]....

I soon found I had to change Type to Structure, but then in the declaration of transrec, transtype acquired a wavy blue underline with the error message: "'transrec' cannot expose type 'transtype' in namespace 'Treasurer_2010' through module 'Module1'.So if I can't use the structure in the module in which it is declared, where can I use it?

Upgrade From Quick Basic On XP?

Nov 12, 2009

I used to write programs in Quick Basic on my XP computer. I now have a Vista (64bit) computer and everybody knows (except me) that those programs won't run on my Vista computer.I want to be able to write single user programs on my Vista computer like I did with my XP computer. Since I'm somewhat familiar with the Quick Basic language, I want to stay in the "Basic" language family. What do I need to have on my Vista computer that would allow me to write and run simple single user programs?

File I/O And Registry :: Random Access Files In .NET?

Nov 2, 2009

how to read and write random access records in .NET. Now I know random access files are dead and the response on every query I found with google/bing/yahoo searches was don't use random access use Binary serialization but I can not. I have a situation where I need to read and modify 256 byte records in a file that is used by another application.

Now for a bit of background the file is made up of 27 fixed length records of 256 bytes. Each of the records has a separate structure consisting of 30-120 fields. The proplem I am having is I can create the record structures but when using the FileGet method I am receiving an error. Now I have found samples that showed the same format I am using that claim to work.

The error I am getting is Option Strict On disallows narrowing from type 'System.ValueType' to type 'ProgramName.ModuleName.Record' in copying the value of 'ByRef' paramater 'Value' back to the matching argument.

The basic layout (simplified) is as follows:

Structure Record
<VBFixedString(6)> Public SomeParam as String
Public SomeNumber as Short


Now the overloads for FileGet show all of the data types including Object. But I have tried various methods to retreive the 256 byte record but without success. Do I have to actually read each of the several hundred fields of the structure one by one? Or am i overlooking something (I have been known for this in the past)

Or (and I'll kick myself if this is the only way) do I just have to set option strict Off in the module and the code as above will actually work.

I would love to be able to just ditch the random access file but I have to keep it for compatibility with several other applications at this time.

How To Read Existing VB 6 Random Access Files

Oct 30, 2010

I have 15 years' worth of files (approx. 10,000) that were created using VB6 structures and stored using the random access method.I am trying to write a conversion routine that will read the old structures and put them into a new format that is more compatible with the .net environment.I have not been able to successfully read any of the old files using the tools available in .net.Each file starts with a header record structure. The header record tells me how many tags are in the file.The next record (ie record number 2) is the first tag pointer record in the file.

There are num_of_tags of the pointer records.Each pointer record has the string that holds the tag's 'literal name and two long integers that tell where in the file this tags records are.Those actual records are stored as History data structures, [Code]

Save Data To Random Access Files?

Sep 6, 2010

how do you save data stored in an array of records (structure) to a text file using StreamWriter? I currently have

Private Sub btnSaveToFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveToFile.Click
Dim sw As New StreamWriter(New FileStream("EmployeeDetails.txt", FileMode.Create, FileAccess.Write))
For Each record As EmployeeType In employees


but it doesn't work. My array is fixed and currently has 3 elements (for testing purposes). If I enter two records and add these to the structure I get the following data saved to the text file:


How do I stop unused elements of the array being included when writing to file? Should I use a dynamic array instead and if yes, how do you use dynamic arrays with structures?

Random Access Files - Lengthen The String (or Even If It's Longer Than 3 To Begin With)?

Jan 24, 2009

I'm working with random access files. I created a module and in it put the

Structure PersonData
Dim Name as String
Dim Age as Integer[code]....

The problem is strange... it will let me input string lengths of 3 for Person.Name and Person.Description and it will save correctly, however, the moment I try and lengthen the string (or even if it's longer than 3 to begin with), I get a 'bad record number' error.

Will VS 2010 Express Read, Write To Random Access Files

Apr 19, 2011

I have recently decided to give .net another chance, but i have a few questions about it before i get really into it. RE: Files, I use random access files to store data as opposed to databases (namely i don't see the need for a database for storing so little information(records <200 max) knowing that it is an older system and less "cool" i don't care...) Will vs2010 express read, write to random access files? Would it be done kind of like vb6 (which is my current vb version)? I will be needing to print the text of rich text boxes, is vs2010 express capable of doing this?

DB/Reporting :: Searching For More Effective Data Storage For Quick Access?

May 12, 2008

I am quite green to VB .NET and it start occuring to me that I am doing things probably in a very ineffective way.Anyway here is the problem I have datasets, consisting of integers there is set 1 which is of format ID, ID2 - ID here is unique but different ID can refer to same ID2. Before I start reading in the data I have unknown number of these entries (ID and ID2 can be at least as high as 99999999)

Then I have a second data set of format ID2 here is the same as in the set 1 and it can contain several PID entries (all integers). In this set the ID2 is unique and again for one ID2 there can be unknown amount of these PIDs, same PID can occur more than once.

Get The Vb Random Function - Basic Winapp Application

May 13, 2010

I must say I don't get the vb Random function. Try making a basic winapp application, but a button named Button1 and a few (around 10) labels on the form. Then add the following to the forms codebehind:

Public Class Form1

Public Function RollDize(ByVal iDize As Integer) As Integer

Dim iRes As Integer


Now, if you click the button, you will see that all the labels get the same number. However, if you step through the code in debug, the numbers are random.

Random Selection Of Categories Without Replacement In Visual Basic

Sep 5, 2011

Here's the program. there are five categories say a, b, c, d, e, each in a textbox (color blue). There will be a command button say "choose". If i click the choose button, it will randomly choose one category and that corresponding textbox example "a" will change color(color yellow). Then if I want to click the choose button again, the selected category "a" from the first selection will change to gray, then a new category will be randomly chosen without "a" in the list and again will change to color yellow. and so on. So I can click the choose button five times, exhausting the five categories without repeating the category that was already selected.

VS2010 .NET And Windows 7 Access Denied On Writing To Or Creating Files In Project Files Folder?

May 22, 2012

Ok I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloadsfiles from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.

After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.

So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install andwork like when we installed on XP.

Converting A VB9 Application From Using Access DB To SQLServer

I have been developing a VB 2008 application which has been using Access as its database. The app is very far a long with about 30 forms and 45 DataSets I now must change the application to use SQLServer. Unfortunately all of the Table & Attributes names have changed in the new DB.Almost all of the data model has stay the same.

I have a few questions on the conversion.

The ConnectionString is currently pointing to the Access DB. I have entered the new ConnectionString into the Setting tab. What is the best approach to make the change?

I have done some testing to change the Table & Attributes names by using Quick Replace. It seams that sometime when I would do the rename I would lose the TableAdepter on some screens.

What is the best approach to performing the renaming task?
