Different Results In .NET And VB6 Using FileOpen Openmode.binary?
Mar 22, 2012
I am trying to convert a VB6 program to vb.net that parses DVD IFO files but using the openmode.binary and InputString is returning different results then it's VB6 counterpart. When I compare the results in the string variable tmpIFOFileIn it is completely different and of course wrong. how to properly convert this VB6 code to vb.net.
vb.net code:
FileOpen(1, ipFileName, OpenMode.Binary, OpenAccess.Read)
tmpIFOFileIn = InputString(1, FileLen(ipFileName))
tmp_i = FileLen(ipFileName)
FileClose(1)

I'm working on converting this code:
FileOpen(1, Application.StartupPath & "Stub.exe", _
OpenMode.Binary, OpenAccess.Read, OpenShare.Default)
From VB.NET to C#.NET. I've used a series of online converters, and they don't really work for me.

I've been using things like FileOpen, and FilePut for a long time in VB.NET, and it's never presented any problems. However in my latest project I'm using CodeDom to compile at runtime, as you know FileOpen, and things like that are the old VB6 methods, such as MsgBox("Msg"), and these don't work. So I need to know how to do this using only the newer VB.NET code.

I have a program that works I would just like it to be able to find the file with out me specifying the actual path. Because if it is on someone's computer other than mine the path might not be correct and it will not function properly. Here is the code I have done. The file it is looking for is of course names.txt. I have not been able to find much info on this.

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out...
I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically. here is the culprit!

I have an image stored in the database as varbinary(max) When it's read out into a datatable, it's only being displayed as System.Byte[]. I've tried every trick in the book to get the binary in string format so I can write it back to the varbinary column in another database.

I am writing lots of numbers to a binary file, using the "My.Computer.FileSystem.WriteAllBytes" method. I'm struggling with reading the numbers back in....
Code:
Private Sub trial()
Dim vals1() As Byte
Dim vals2() As Byte
[Code].....
How do I know where one ends and the next begins? This is especially important because the length of vals could be something other than 8....

I have seen writing to binary, but the question is how do I change from where it starts at in the file, supposively I want to start at byte 3 instead of the end or begining. Also is it 0 based? where zero is the first position, and how do I over write the data at the part I am at in position 3?[code]....

I need to be able to write data to a binary file. No problem - I have a test app I've knocked up that reads and writes to them fine, however the format uses C0 and C1 control codes, and I have no idea how to write them properly. The SOH, ENQ, DLE, NUL type of thing. I'd post some but they are non-printing. I know what they mean and what they do but have no idea how to write them.Basically we are writing our own system that generates test data files for import by another program. My files that I write have the correct number of fields and correct value and formats but because I can't get the tags to write they data is imported incorrectly. I've spent days reading up on it but can't find what I'm looking for.Not dealt with binary data files in VB before so this is all new.

I used backgroundworker to receive file segments from a server, it taking the segments and save them directly to a binary file. the problem is,I using a global variable to store the "FreeFile()" number.when "backgroundworker" receive "START" it do F = FreeFile()
when it receive "Segment", it should append to that file, but the problem is ... backgroundworker no more recognize the file (which its identifier saved in global variable F) and telling "Bad File"?!
whats the soultion?I think about opening the file and close it each time (not leave the connection to the file available). But I didn't figure out how to append to Binary files, It always replace their contents. and If I use "Append" option it corrupt the file!

Binary Search in ListBox
View 4 Replies
Apr 11, 2011
I am trying to write a program which performs a binary search. The user will input the name of a state in a textbox.I have a listbox which is populated with the 50 states in ABC order.The middle of the list must be determined and then determine which half of the list the state may be located. If the middle item is less than the state name the state should be in the second half of the list. If it's greater than the state name is should be in the first half of the list. The calculation for looking at the middle itemi the list is:
middle = CInt(first + last)/2)
There is a variable 'flag' which is initially set to false and then will be set to true if the state name is found. The variable first is initially set to 0 and last needs to be set to one less than the number of items in the list.Below is a very rough program fragment.
Code:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Dim i As Integer
Dim flag As Boolean = False
Dim first As Double = 0
