Saving/loading A Background Image From Registry?
Jun 15, 2010
I'm trying to build a music player app. I want to have it set up so the user can choose your own background from picture files on your computer. The code I'm using to save the registry file is:
Private Sub MusicPlayerForm_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
My.Computer.Registry.SetValue _ (m_strKeyName, "BackgroundImage", Me.BackgroundImage)
End Sub
The file is saved and I can see it when I use the regedit. The problem I'm having is loading the file. Currently I have:
Private Sub MusicPlayerForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Timer1.Start()
LoadDefault()
[code]....
The error message I get is 'System.IO.FileNotFound Exception'. For some reason I don't think the files' getting read.

I also want to fill the image background with a color of choice, which is saved in a PictureBox control (ColorBox1). I suppose I need to draw a rectangle like[code]...

I would be grateful if you helped me. I've built a text editing application and I would like it to load values/user settings from the Windows Registry. Here's my code but it is somehow wrong (I believe it whatsoever has to do with wrong syntax but it could be something else);

I am loading an access database in vb.net using
me.adaptername.fill(me.datasetname.tablename)
The thing is that this takes a lot of time and the program doesn't move on to the next line until it finishes loading all the data. Some of these tables I need only later but I don't want to make stall work while doing it. Is there a way to load a database without waiting for it in the code. and a way to check if it finished loading in code. this way i'll be able to load it in the backgroud after the program has started and if the user wants to use options which require tables which weren't loaded yet i'll be able to know and avoid errors.

Ive been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?

what I am trying to accomplish worked with the code in the last thread I posted a while back. I still am using this code, however, I changed the window size to work better and gave it a nicer background for the title screen of my project. Now what I am working on at the moment is making a settings form that has 2 labels. One for "Default" Layout and one for "Plain" layout. When default is at start, the default label is disabled,and when plain layout is clicked, the button is disabled and default button is enabled.Basically, this is a toggle switch for default or plain where if one is enabled, the option for it is disabled and the other is enabled.My problem is that when I switch from Plain back to default, the background Image will not switch back from the plain background color of "control"Here is my code:
Public Class Settings
Private Sub LinkLabel1_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinkLabel1.LinkClicked

I have a rather straightforward question.How to I get a DataGrid in WPF to save/load raw XML files and have the ability to display/edit them with other controls? The application will only work offline so I won't need SQL. Just simply open, edit and save data to XML.

I'm making a log for my application.I have made the log and it works.I use the streamreader and the streamwriter to save and load the data. I thought that it would be more organized to have columns inside the log.The problem is how will i save the information to the text file and load it up again so that it could organize itself again. The code that i used to make the columns.
log.Columns.Add("Task performed ", CInt((log.Width - 4) * 0.3), HorizontalAlignment.Left)
log.Columns.Add("Time and date", CInt((log.Width - 4) * 0.2), HorizontalAlignment.Left)
log.Columns.Add(" Amount of detected files(s)", CInt((log.Width - 4) * 0.2), HorizontalAlignment.Left)
log.Columns.Add(" App version", CInt((log.Width - 4) * 0.4), HorizontalAlignment.Left)
The code that i use to add the information to the log.

I can't find any way of loading all files with e.g (.txt) from a specific directory: C:UsersChristianDocumentsMy Logs I use Visual Basic 2008 .NET, this is how I try to get it:
1. When the form loads it should retrieve the full path and title of the files and then put them in the List View control.
2. When the user marks one file in the list view and then clicks a button the text content should be displayed in a multi line textbox.

I'm looking to work on a project at work and I'm preparing to do my home screen of my program and I'm stuck on how to prep for all of this. I want to be able to save projects (and its not just one form that will be saved, 26 future forms to be exact), load projects, create new projects and view available projects to be selected from in the home screen. Really a very standard home screen when concerning professional programming. I'm not quite sure how to go about this or when looking ahead what might be a best practice. I haven't worked with databases, so my knowledge is limited.

Using the Microsoft VB 2008 Express program, I'm making a SWd20 character sheet (D&D) to be distributed to a few friends. It's a program where the user can figure out stats, species, class, etc without having to make any calculations him/herself.. but this will all be in vain without saving it..
So I'd love to know how I could make it so the user can save and load the entire file(including buttons, labels, text boxes, menu strips, possibly multiple forms, etc) on his/her own computer.. Is this possible, and if so, how can I go about this?
I've already searched through and found lots on saving text in the files to .txt files, but that doesn't cover everything I need

a member mentioned, xml is similar to a txt file. txt files, i can manipulate quite well. so, if this is the case, it should not be to complicated to do as the thread title describes . that, of course is, if you already know how to even create an xml file. i do not. any and all input/suggestions welcomed, links for xml noobing welcomed as well.

I am doing a project for part of my coursework which involves the creation of a series circuit designer.
I am having some trouble with the saving and loading functions; I had intended to save them to a text file with commas separating the component name and the value (if any) attributed with it.
Grid(xcoord, ycoord, 0) contains the component name. Grid(xcoord, ycoord, 1) contains the attached value (resistance or voltage- components such as wires have a value here of 0)
Once the save button is pressed, the text file contains 50 rows of "0".
P.S. Let me know if any other parts of my program are required.
Dim comp(maxsize) as ccircuits[globally declared]
Const maxsize = 50

what I am trying to do is get a program to load data from a text file with multiple lines in the form "Name, Type, Stocklvl, Price, Location, Reorderlvl" then display it all in a data grid. From where it can be viewed and edited as well as saved back into the original file stock.txt as well as generating a separate file reorder.txt which includes data on what needs to be reordered and the date which updates on program exit. I have chosen to use datagridview something I'm unfamiliar with as I figure It'd probably be the most functional to meet my needs of displaying a lot of data clearly as much as 200 items.

I have a little piece of code which saves a certain Bitmap to a JPG image. The Bitmap is "composed like this" ( Ppiechart is a picturebox):[code]So After it is declared I start to do some drawing on this bitmap. And then I want to save it like this:[code]So this saves the image. But the problem is that the background of the image turns black when I open the file on my PC.The background of the Bitmap in the program itself is white. So does anybody have an idea what may cause this? Do I have to declare a color for the "mybitmap"?
