Nov 15, 2010I want to create a VB program for my final year project,the contents of which can be editable by the user, for example when new information becomes availabe it can be easily added. Now,I thought that this could be done using the text box, although it doesn't seem to be possible.

Control Added On The Fly Is Added To The Wrong Location Of An Auto-scroll Panel?
Jun 21, 2010I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500. To see what I am talking about, create an empty "Windows Forms Application" project and insert the below code into it.

View 11 RepliesOriginal DataTable Object Has Columns Added When Variable Has Columns Added?
Oct 6, 2011I have a datatable property called prpParametersTable in a class called clsBatch. I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem. When I add the three new columns to dtP my original table prpParametersTable also gets those columns added to it, why? I only want to add the three columns to dtP and not prpParametersTable. How can I do that?
Private Function prvfnc_InsertBatchParameters(ByRef cnn As SqlConnection, ByRef trans As SqlTransaction) As String
' set new columns that have BatchID, Insert DateTime, and UserID for the SQLBulkCopy method below
Dim clm As DataColumn
Dim dtP As DataTable = clsBatch.prpParametersTable

OLEDB Connection - Pull Information From Three Different Database Tables And Compiling The Information Onto One Screen
Jun 9, 2011The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

Method Which Check If A Certain DSN Exists Then If It Does Extract Information And Use Information For Connection Purposes
Feb 2, 2011I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.

View 4 RepliesRetrieve Information From A Binary File, Alter That Information, And Put It Back Into A New File?
Aug 27, 2009I am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.
This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:
Read through the file with a system.io.binaryreader
Searche for a bytestream that will signal data is coming
For example:
If System.IO.File.Exists("C: est estread.wav") Then
Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30}
Dim i As Integer[code].....
And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?
I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.

MySQL Count Rows Count Rows And Gain Access To Other Information In A Row Based On Provoided Information
Oct 8, 2009I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).

Added A Button In Datarepeater?
Jan 16, 2011I have added a button in datarepeater. If clicked once, it executes code and Button.text should change to Yes. Clicked again, it executes the opposite code and button.text should change to No. Codes are being executed (I am using flag variable) but Button.text is not changing.
How to change this text. I am simply trying Button.text="Yes" but probably I need to give some reference of the row no. too. How to do it?
Added A Subform In VB From SQL Dataset?
Nov 8, 2011I am trying to create a Form that can be filled out in it's entirety without having to bring up other forms. It is considered in access to be a subform. I have one table that includes Injuries and each injury has a specific ID well I have all the information that goes with it updating, except for the "many-to-many relationships"...I one want injury to have more than one treatment type, the problem occurs when I drag the injury table over from my dataset it automatically creates a binding source for it, which only controls the data inside that table. It does not control the data that is related to it such as "treatment type" "body part injured" . There must be a way to have a single Inj

Asp.net - Dynamically Added Controls In .net?
Jan 15, 2010I understand the page lifecycle and how i need to add the dynamic controls on page_init if I want to take advantage of viewstate. Also I know that I should try to avoid dynamic controls when possible. The dynamic controls are created depending on an object that is created from custom event arguments sent from a custom treeview. Problem is I need viewstate so I need to create them in page_init but I don't have the event args to create the object that tell me what controls to add until later in the lifecycle.
Private Function GetEventArgs() As npTreeViewEventArgs
Dim control As Control = Nothing
Dim e As npTreeViewEventArgs = Nothing
[code]....
I use this in page_init to create my object and controls.
