I'm trying to design cathodic protection for offshore pipelines using visual basics. However, I'm not very familiar with vb. I'm hoping I can start with basic calculations like finding pipe surface area etc. how I can design a dialog box to input pipe dimensions like length and diameter to enable me calculate the surface area?
View 4 RepliesI need some help with the input validation of my application. Attached is the code that I have written as well as a screenshot of the front end. I specifically need input validation to verify that the user selected input for cbLengthOfStay is a number between 1-10 as well as input validation to verify the user input for txtMedication, txtSurgicalCharges, txtLabFees and txtRehabilitation is a positive numerical number. Please feel free to critique my attached code. [Code]

I am trying to implement a controlling design logic that prompts the user for a length and the area to calculate until he or she enters a number less than zero in the length to end.So far I have it where I believe it�s doing the calculations but it�s not ending when I input a number less than zero or zero.

I have 2 applications that needs to talk to each others. After some research, I wanted to go with managed pipe (namespace system.io.pipes). The problem is, the client must send commands to the server but need to also wait for incoming message from the server at the same time. I tried to go asynchrone but it doesn't work.

I'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double()
Dim i, j As Long
Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.
i have found the Hwnd for a window and i now wish to get information about this window, the location on the screen of the window and its width and height. Problem is the values i get are not anything near right.

Private Shared Function GetWindowRect(ByVal hWnd As IntPtr, ByRef lpRect As Rect) As Boolean
[Code].....
this returns 0 for height and width and the remaining figures are nearly 0 (1.68E-311) what am i missing and how can i get this information?

View 1 RepliesI've checked various numbers of resources to try and find a way to create a multiline input dialog box.IE something that is a simple inputbox() with any number of lines in it or capable of a scrolling multiline dialog box.
So far I have found nothing. I know I can create one using vb Studio, but i'm trying to write a script for SecureCRT that will allow multiple lines of data to be input, then only certain information pulled from that data, run in a command, then the output set to a file. This will then loop and append any further output data to the end of the same file.I've so far got it built to ask for how many times it needs to loop based on how many servers we are checking on, but we are looking to cut the time down to where we can copy the info into the clipboard, paste it into a text box (when prompted for a mutli server check) then run the above paragraph as noted.

I tried to make a phone book but I having some problems inserting it to the databank and then updating the Datagridview. I use a Dialog to input the contact details. I have 7 dialog's and 7 Label's.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'I have set it to false so they have to use the dialog to make the contacts but I don't think its the best way'

View 16 RepliesI'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much

Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.

Looking for a basic UDP Pipe or redirector. Should of course be able to see both client 2 server and server 2 client data.Here is what I tried but it fails because I don't know when to call which Receive..Say I call
data = serverUdpClient.Receive(sender)
Then I have to reroute this, so I call this
clientUdpClient.Send(data, data.Length)

Pretty much the code flow is all fucked.. because it's socket is blocking. When I started working on UDP.. all examples say stay away from non-blocking as it's too advanced for newbie's trying to work with networking sockets.. I find that statement wrong.. the other way around!.

Public clientUdpClient As System.Net.Sockets.UdpClient

Also tried this.. doesn't work properly.

If serverUdpClient.Available > 0 Then

I have a perplexing problem. I have written a DB App using SQL Express 2005 as the back end and Visual Studio 2005 Standard VB.Net as the front end. I have a master DB that needs to import from an external database from another SQL Express server. I detach the DB from that server and attach it to my server. I import the data I need, close all connections to the import DB and try to drop it from the server since it is no longer needed. Yet one active connection remains so I get a drop error. To get around this problem, I set the import DB to single user with roll back immediate and then drop the database. However, when my application tries to access the Master DB I get the follwong error

I have a lot of Microsoft SQL Backup files. The application should restore each backup-file with
RESTORE DATABASE {0} FROM DISK = '{1}' WITH REPLACE
Then I fill another database with some data from the restored database and drop the restored database with
DROP DATABASE {0}
If I only restore one backup-file, no problems. The data from this backup is in the new database and the restored database is dropped. But if i use more than 1 backup-file, i get this error:
German:Fehler auf Übertragungsebene beim Senden der Anforderung an den Server. (provider: Shared Memory-Provider, error: 0 - Kein Prozess ist am anderen Ende der Pipe.)English (something like): Error on transportlayer while sending the request to the server. (provider.

Currently I am building an application that will do Data Validation on an Excel Spreadsheet.The application will allow a user to load an Excel Spreadsheet in and runs checks on the data. The application needs to export the spreadsheet as a pipe delimited file with all of the fields separated by the character.Currently I have written an Excel Macro that will export it as a Text File then delimit it and save the text file as a .ps1 file.

Just trying to get EXIF information using ImageMagick. If I set the variable command to:-
"C:Program FilesImageMagick-6.6.2-Q16identify.exe" -ping -format "%[exif:*]" "C:est.jpg" >c:exif.out
And then:-
Shell(command, AppWinStyle.Hide, True)
I don't get an exit.out file. There's a delay so it's clearly doing it. Obviously the same line from an actual command prompt does work! And I get an exif.out file... Any idea how I can shell that command off and get an output file?
Now i'm coding for a project in VB.net that allow user to browse to text files (i am done), after that i have to import this text file into access.
The problem i have to import a pipe delimited file (it is: #), that '#' help to distinguish each filed.
Example: my text file is: #BC2323#23241#12345. This mean that: There are 3 fileds in it: BC2323; 23241; 12345.
There is my coding for browse any text file:
Private Sub btnBrowse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBrowse.Click
Dim alltext, lineoftext As String
OpenFileDialog1.Filter = "Text files (*.txt)|*.TXT"

I have an API that loads into memory from a button click. It can then either load an approx 10MB txt file (ASCII comma delimited characters/decimal list as a string) or live timed data from the internet. The idea is to be able to view the data in a text box. From there I can see what I am doing as far as spitting that info into a datagridview or database. The data is completely out of order in the txt file but has various Getinfo Functions / DLL's accessed via button clicks that split the data into its correct format to display in the text box. The problem I am having is not having fixed length strings in VB 2010. I don't know enough to work out if there is a simple work around or something more complicated required. Everything I have tried has left the textbox empty.
VB 2005 code that works:

I am pretty sure that my questions will soon get so annoying you won't answer them, but before it happens.I am using DrawCurve (with density set to default) to draw on my picturebox. I need to know the exact length (well, not *exact* but knowing it is around +/- 1px from exact length would be nice) of the curve drawn.
Is there any function in API I could use to get what I want? If not, could you point me to the algorithm (preferably implemented in any language) that I could use with array of points as an input and length as an output value?
I have a title (in one line) that can have different lengths. I need to print this title on A4 landscape - page ( draw string in print page event), but always it should be located in the middle of the page, regardless of length. If I want to determine the exact location I have to calculate the length of the string in pixels. Or maybe there is a better way to center the string on page? How can I do it?
View 2 RepliesThis is related to my last question.Even though Access considers Nulls and zero-length strings (ZLS) separate values, often developers wish to treat them as equivalent for the sake of an If...Then statement or some other stretch of code. One way to accomplish this is to write code like this:
' Not so efficient
If IsNull(varAge) or varAge = "" Then
' do something
