How To Pass String Value To BackgroundImage
Oct 10, 2010
I am writing a simulator for a complex technical system. I have created a custom control which inherits from the Button control. My project requires around 100 of these buttons, which function identically except for one difference. The background image cycles between 4 different images, (depending upon whether the button is pressed and/or the state of a Fault parameter), and this group of 4 images is different for many of the buttons. So when I drag a new control onto the form, I'd like to be able to specify which group of 4 images to use for this button.
Currently I'm using this syntax:
if not IsFault and isOn then
MyBase.BackgroundImage = My.Resources.FaultOnButton01
...
But this means I have to change each image in the code for each individual button. To simplify matters I though of using the Tag attribute. That way the class code can select the images by a process like this:
if not IsFault and isOn then
Mybase.BackgroundImage=My.Resources. + mybase.Tag + "01"
Obviously this syntax won't work, so my question is: How can I pass a built-up string value to the MyBase.BackgroundImage?

So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.
String myTestValue = "NotModified";
TestMethod(myTestValue);
System.Diagnostics.Debug.Write(myTestValue); /* myTestValue = "NotModified" WTF? *[code].....
And what is going on under the hood? I would have bet my life that the value would have changed....

I am trying to use string.format on a url to pass several values into the string. It's probably a simple error but I cannot get the following code to work. It doesn't even build the string.

Dim client As New WebClient()
Dim url As String

Can the background image in a picture box be moved, or located some where else, not the top left corner?I am aware of the layout that can be changed but that is not what I am after.

The code;
Private Sub PictureBox3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox3.Click
If user.Right > PictureBox3.Left Then
PictureBox3.BackgroundImage = (My.Resources.dooropen)
End If
End sub
Will not work as it should, when my player (rectangleshape) right is more than the picturebox.left it will not update the picture of the picturebox.

I'll explain this briefly as I need to be sure pretty quickly... basically, I'm developing a game. after the user gets 5 points, an alert box comes up saying "proceed to next level"... on the next (second level) I want the background image to change....
Now the default background is not a picturebox, it's actually part of System.Drawing.Bitmap I am using the same form throughout the entire game, so when it says "Proceed to next level" the game stays on the same form... Here's my Select Case statement to tell it to change the background image:

I am using images imported into My.Resources as images for items in my game. Now for the saving procedure I use pnl.BackgroundImage.ToString but that returns System.Drawing.Image. What I'd like to know is how to retrieve the name of the resources object that is the image of the panel.

I have a panel that has a BackgroundImage set to "zoom". Because of this, the image usually has some grey "letterboxing" showing the panel beneath the BackgroundImage. I want to paint on the Graphics Object of the Panel using its paint event handler. Is there a way to contrain my painting to just the image part of the panel? Is there a way to find the rectangle that the BackgroundImage is occupying within the panel?
P.S. I don't want to make a graphics object from the BackgroundImage because I'm already using that for some other "paint layers".

A tabcontrol's backgroundimage caused severe flicker problems when resizing a windows form. By setting that property to NONE at designtime and that adding it at the very end of the processing pipeline & after the window had been maximized, the flicker problem on initial form load was solved.
HOWEVER, now when a tabpage resize event is fired, I would like to remove that image at the beginning of the resize and add it back to the tabpage at the end of the resize event. The following code however does NOT work. I get an error in the resize event, Property cannot be found.
Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
TabPage.BackgroundImage = My.Resources.GraphicallyIntenseImageToDraw

I'm setting up a simple helper class to hold some data from a file I'm parsing. The names of the properties match the names of values that I expect to find in the file. I'd like to add a method called AddPropertyValue to my class so that I can assign a value to a property without explicitly calling it by name.The method would look like this:
//C#
public void AddPropertyValue(string propertyName, string propertyValue) {
//code to assign the property value based on propertyName
}
'VB.NET'
[Code]...
Is this possible without having to test for each individual property name against the supplied propertyName?

I can pass integers, singles, doubles, and arrays of all these back and forth with no problem. But I can't figure out how to pass a string in Visual Basic 2010 to a character variable in the Fortran DLL. I keep getting the PInvokeStackImbalance error. I could just convert the Visual Basic string to an integer array containing the ASCII code for each character, send that, and convert back inside the DLL, but that's pathetic. There must be a simple way to do this.
I first tried using Dim txt(50) as Char in VB2010, and character*50 txt in the DVF F90 DLL but that didn't work.
Then I tried Dim txt as String in Visual Basic 2010 and made the string 50 characters long (also tried 49) but this didn't work.

I have written a program that performs multiple httpwebrequests. It reports in to me by writing to the console. In the past, i have used a backgroundworker for this task, but the code became ugly and bulky. Now, i use threading.thread to start the background process. However, i can't seem to find an explanation on updating the UI from the worker thread.
I've read a lot on delegates, invoke and lambda's, and i just got more confused.
Let's say, in my current program i have this line to be displayed in a textbox on my main form:
"Error reading events!"

If I send a String set to Nothing as an input parameter to a SQL stored procedure, and in the sproc it's like this @MyString Char(9) = NULL, what does it turn NULL into? Because I'm firing the sproc and it's not firing the statement that says IF @MyString = NULL... So I don't know what it is... Or how can I pass the string as a NULL if nothing is passed as a parameter to my calling function?
