Using OutputTextBox.AppendText In Making Triangles
Aug 1, 2010
I am trying to just make triangles as follows, but when I execute the program, nothing displays in my textbox. It is a windows forms application.
Should be :
*
**
***
****
*****
.....................
Here is my code:
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox.TextChanged
End Sub

Given the image below
1. I have updated the image based on feedback from Steven_W so there are 4 triangles in the right hand diagram instead of 3 which makes more sense!
2. update image again to label sub triangles as A, B, C, D in grey
What is the pseudo algorithm for mapping a coordinate (x,y) in the left hand square such that a coordinate (u,v) is produced within the rectangle bounding the triangle on the right so that points are interpolated between the mapping points as illustrated on the diagram? 1 to 4 are equidistant on the triangle from left to right even though my illustration is a bit rough around the edges :)This is to generate a rough and ready panel for the lid of a skybox from the top half a 360 degree panoramic photo.
update 3 based on feedback.The first step appears to be working out which triangle we are in for the left hand diagram based on the (x,y) coordinates.The second steep is to work out the distance along the vertices of that triangle. Then use those distances to get the coordinates on the related triangle in the diagram on the right
update 4 - code to identify triangle in left hand diagram
Public Function TriangleIndex(ByVal x As Integer, ByVal y As Integer, ByVal w as integer, ByVal h as integer) as integer[code].....

Randomize()
For x = 0 To 8

I'm looking at the MSDN webpage for TextBoxBase.AppendText Method [URL] Under requirements I see "Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2

After exporting data using a third party component the data in the excel sheet isn't type correctly. Excel thinks that some values are string while they are numbers and a little green triangle shows up.
We've coded the following to fix this:
For Each objCell As Microsoft.Office.Interop.Excel.Range In objWorkSheetReport.Range(objWorkSheetReport.Cells(1, 1), objWorkSheetReport.Cells(Me.RowCount + 10, Columns.Count + 10)).Cells
[Code].....
This removes all those little green triangles but is really slow.
Is there a faster way to convert a Range of data quickly so the green triangles don't show up?

I'm trying to make it so when my program is started, a text box ("log") automatically says: [code] I have set the text box to say "Placeholder1" using properties but I am having problems coding the rest. I know this may be easy but I just started in VB so tolerance please. [code] When I attempt to run it I get this error:Argument not specified for parameter 'text' of 'Public Sub AppendText(text As String)'.

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]

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.

I've programmed in C# for the majority of my .NET career - now I'm working on a VB.net project - when debugging it drives me insane the differences of how the debugging works.two off the top of my head are
1) having to prefix my immediate window queries with ?
2) not being able to mouse over a GUID, I have to ?myGuid.ToString() to actually see the value is there a way I can make it behave like C#?

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 have made new MDIChild and with textboxes on the form. When the form loads...it will open data saved from a text file to the textboxes. However the data does not load from the text files. When i take out the code, it works fine...but it needs to be a mdi child...the code i'm using is
Dim NewMDIChild As New ViewCustomer()
NewMDIChild.MdiParent = Main
NewMDIChild.Show()
the form that I need to load the info is "ViewCustomer" and the mdi parent is "Main"

I Have a simple notepad, and a toolstrip, inside the toolstrip, it has an option to find and replace the text in textbox one. I made a new form, inside that project, and named it find. Now how can I make it so that when they click on that toolstrip option it opens that form? Also, will I have any troubles being able to find the text since they are two different forms?

I used Microsoft Visual Basic 2008 and i am having trouble making it to where i can make a screen that a video can be played in. I mean i know i have to code it to call if from a folder but i do not know how to set up the form so i can make my own program. My teacher said that there used to be a thing where you just put in on the from and it did it for you is there a special thing you have to download to do that or do you have to actually go through and code it yourself. I do not want to be given code i just want to know the best way of starting my project whether it is making a thing so that i can play the videos

I have created a project to update my applications; it is simply a form, with a progressbar and some other fancy stuff, which will check for updates via FtpWebRequest and download files if necessary. I have code it so that in order to use it for other applications I only need to change the ftp folder address and the .exe name for the main application to be started.
So the question is. Is there a way i can put that project in a dll so that I can simply pass it to my partners without having to pass the source and obviously have some way to change the ftp folder address and the .exe name like some kind of properties�.

I'm trying to bullied a simple cheap software to rise money.Any way, I managed to make a serial login form but the problem is I need it to appear only once pear purchase, meaning as soon as you enter it once, it will be saved and the login form wont popup when the program gets started again on the same PC. Here is my code so far:
ic Class Form11
Private Sub Form11_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'm really interested in programming things for games (NOT cheats, more or less things that make the gamer's life easier) and most of my ideas end up relating to an OCR, but I've got no idea where to start making one or how to make it at all, really.
I did a quick google search but all I could find were libraries to convert bitmaps and such to strings, which is not what I want. The game I'm making this for specifically is browser-based, so unless I were to take a screenshot there wouldn't be much to work with since there's a ton of text in addressbars and such.
The main focus of my OCR is to allow automatic PIN entering for banks in the game (PINs are used for security purposes, but lazy people don't like entering them). There's a keypad on-screen with 9 boxes, each with a number, but after every click the numbers change positions inside the buttons and they also switch positions with other buttons (note that the buttons stay in place and do not change color or anything).
