Add Text BELOW Bitmap In Program?

Mar 29, 2011

I'm trying to resize a .NET bitmap without actually scaling the image. The idea here is to create a space above and below the image, fill it with a black rectangle, and place some text there (without covering up or destroying any part of the original image).

All the code and examples I've seen of this thus far just show how to scale the image, not expand the canvas. So far, everything I've tried on my own also scales/stretches the image.[code]....

Program Run Out Of Memory - Draw Segment Of The Spline To The Bitmap

May 31, 2009

I am building an app that builds a bunch of cardinal splines by storing their PointF structures in arrays. As the program runs, new points are added to the arrays, and the graphics are drawn to a bitmap. I can let it run for ages and the splines just keep growing like they should with no problems. The amount of points in each spline can grow into the thousands. To speed up execution as time progresses, I don't completely redraw the splines after each pass, I simply draw the last segment of the spline to the bitmap, having let the bitmap 'record' the earlier part of the splines.

But if I pan across the scene or zoom in/out of it, then I DO have to completely redraw the splines, since the size and resolution of the display is limited to its dimensions. Panning works, no problem. But if I zoom in and out of the bitmap with the mouse wheel, after about 14 wheel clicks, I get an "Out of Memory" error. BUT...I have it set up so that whenever the mouse wheel turns, the graphics and the bitmap are disposed so that new ones can be built for the new zoom setting. So why would the program run out of memory when as far as I can tell, I am disposing of all my unused, unmanaged resources on a regular basis?

How To Create A Bitmap Image Using A Text File

Jan 9, 2010

I am trying to convert from a text file to an image(bitmap) file.
For example, test.txt: 01 23 34 56 78 90

[Code]....

The first step will be reading the data, so I created some VB codes:

Dim openFileDialog1 As New OpenFileDialog()
openFileDialog1.Filter = "Text Files (*.txt)|*.txt"
openFileDialog1.Title = "Select a text File"
' Show the Dialog.

' If the user clicked OK in the dialog and ' an image file was selected, open it.

If openFileDialog1.ShowDialog() = DialogResult.OK Then
' Open file.
[Code]...

The second step will be converting the data to some data format which can be used in a bitmap image. This part is making me confused. Some codes I made is listed below:

I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

Flash Card Program - Type All The Words On A Text File And Have The Program Randomly Pull One Of Them

Feb 15, 2009

Anyway, I'm a teacher and am writing a program that simply shows kids a word on a flashcard. There are 2 buttons, 1 to read the word and 1 to go to a new work. There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).

Here is the code so far:

Public Class Form1
Dim word
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

DB/Reporting :: Database - Access Denied To A Text File (since It's Stored In The Program Directory In The Program Files)

Sep 20, 2010

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.

Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?

Here's an example of what I would do:

Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc

So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).

So to cap up the few questions I have:

-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?

VS 2010 Make A Program In Which If The Textbox Text And The Listbox Text Are The Same Order?

Apr 25, 2012

im trying to make a program in which if the textbox text and the listbox text are the same order, which they are in the picture, a bluie fonted text saying well done appears. However only the red text appears which is only meant to come when the order of the text in both listbox and textbox isnt the same.

Here is the code that i used for this:

listarrays = name of listbox
textbox1 = name of textbox

l is the name of the label for correct answer(blue font)label3 is name of label with red font which should only appear for wrong answer

Dim text As String = Me.TextBox1.Text
For Each item As Object In listarrays.Items
If item.ToString = Me.TextBox1.Text Then

[code].....

use another textbox instead of the listbox but thats just making itmuch harder for me as I already made the full code working with the listbox. My lecturer told me i need to convert both in string so both textbox and listbox are compatible and i did so (see code above) but the correct label doesn't show?

VS 2008 - Simple Text -> Xml Program - Save The Contents Of The Bottom Text Window To An Xml File

Dec 23, 2009

I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:

Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.

Here is an attached screenshot of my program layout so far:

I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.

Process - Program That Will Paste Text Into A Second Program

Jun 10, 2011

I mainly just build little apps that are mainly useful to me. So please be gentle.

I am currently working on a program that will paste text into a second program. The text will paste into several different fields automatically.

The problem I am running into is that I need my program to check for running processes(as the second app will already be running). I seem to have done this just fine. When I then need to "use" that process

I use myprocess.start()

This of course starts a second instance of the application in question.

How do I basically use a process that is running as if I used the command .start()?
