Making A Message Box Work - .NET?
Mar 15, 2012
Below is the code I have been working on in VB.NET What basically happens is that when the user presses the calculate pay button, a message box is supposed to appear with all of the information in it, however the error comes up with: 'InvalidCastException: Conversion from string "Total pay: 5" to type 'Integer' is not valid.'
Public Class Form1
Dim TotalPayWithoutOvertime As Integer
Dim HoursWorked As Integer
Dim DoubleRate As Integer

I'm an absolute beginner at programming and VB, and I'm starting a course in software development. We were given tutorials to do before the start of the course but I'm having extreme diffictulty with them because they're written for VB 6 and we were told to download VB2008 express since we're using that for the courseI got here? I understand basically what it does, but it gives errors in VB2008 and I can't get the add button to stay greyed out when there's nothing in the name field. I also can't get a message box to pop up when I click Add because 'answer' isn't recognised. I also don't understand what "Following code is entered in the .... event". What's an event, how do I enter it in it?

I've been going through a VB book I had while in College, and was trying to figure out different ways of making programs work.One assignment was to create a multi-dimensional array to figure out wind chill factors. The only part I really can't get to work right is using 2 numericUpDown controls. Using 2 dropdown menus was obviously easy because the items are indexed, but as far as I know, numericUpDown controls are not indexed.
Instead I used 2 selectCase statements to determine the index in each updown control, then passed the indexes to a function to determine the answer.The numericUpDown controls both increment by 5, (wind from 5 to 30) (temp from -20 to 15)Just looking to see if someone has any ideas of a better way of doing this.

I'm using the following code to read some values in from a tab delimited text file:
vb.net
Using Parser As FileIO.TextFieldParser = My.Computer.FileSystem.OpenTextFieldParser(LogFile, vbTab)
Parser.TextFieldType = FileIO.FieldType.Delimited
Dim comments(0) As String
[Code]...
As you can see I have set the HasFieldsEnclosedInQuotes property to true on the textfieldparser because I want to make sure I capture the data correctly if quotation marks are used. If I set the HasFieldsEnclosedInQuotes property to False then it all works (or at least it doesnt error anyway) but like I said, I need to have that set to true because otherwise if the line contained a tab character within the quote marks then my app would think this was two separate fields and process it incorrectly.

Is there a way to make ProgressBarRenderer.DrawHorizontalChunks actually work the same as the standard ProgressBar rendering?
If you create a Class that Inherits ProgressBar and override the OnPaint event then you have to render the Empty ProgressBar and it's fill% manually. This pretty easy with the ProgressBarRenderer. However, the DrawHorizontalChunks function is ugly compared to how a standard ProgressBar renders itself.
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
ProgressBarRenderer.DrawHorizontalBar(e.Graphics, e.ClipRectangle)
ProgressBarRenderer.DrawHorizontalChunks(e.Graphics, New Rectangle(0, 0,

I also have a second more minor issue in that I Shadowed the value property (for various reasons), so PerformStep (which then has to be Shadowed to keep the Value property in check) causes it to increase in blocks rather than smoothly growing between the two Values (old value growing to old value + step); the only solution I can see is to extend the code in the Shadows Sub PerformStep code to move the Value property gradually between the old and new values.

I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.
CODE:
When I click on the icon of my program it shows the error message
CODE:
Reporting details: This error report includes information regarding the condition of WindowsApplication1. When the problem occurred the operating system version and computer hardware is use; your Digital Product ID, which could be used to identify your license; and the Internet Protocol(IP) anddress of your computer.

I'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]

create a message box that stores my user name, message, and post datetime into the database as messages are sent. Soon came to realise, what if the user changed his name? So I decided to use the user id (icn) to identify the message poster instead. However, my chunk of codes keep giving me the same error. Says that there are no rows in the dataset.

I am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

I'm making a simple decoder. Type a message in the "message" text box and it spits out a code in the "code" text box. If you pop a code into the "code" text box it spits out the message in the "message" text box. Seems simple, right? Well here's my problem. I typed "The quick brown fox jumped over the lazy dog" to test it and it will put a lowercase "f" at the beginning, put letters that aren't supposed to be in there in there, and replace what should be upper case letters with lower case. I commented out the code for replacing symbols because it seemed to work fine before I put them in the code but still the same result. I checked over the code to see if I mixed stuff up. Like I accidentally put the replacement for a lower case "e" as the replacement for a lower case "h" but I can't find anything.

I have a class library written in .Net that I would like to make available to VB6/VBA. What I tried did not work (obviously as I am asking this question). Here is what I did:
I Created a Class Library Project in Visual Studio 2010 Express and put the code in a Class Module.I opened the project properties and went to "Assembly Information" and checked "Make COM Visible". I went to "Advanced Compile" options and targeted .Net 2.0 (it's very simple code).I then removed all references expect for "System".I built the project (no warnings or errors) and copied the DLL out of the Bin folder into C:WindowsSystem32 I ran RegSvr32 to register the DLL and got the error: The module "MyDll.dll" was loaded but the entry-point DLLRegisterServer was not found. Make sure that "MyDll.dll is a valid DLL or OCX file and then try again.
