I'm having a hard time displaying random numbers from a button the labels on the same form. This is my first time dealing with VB in general, and I'm having trouble locating this for a project.
I have another assignment as well for my class (which uses an earlier version of VB than me), and I'm pretty much doing everything on my own in a different format for the newer version. how to use an array for images as well?
I'm a beginner when it comes to Visual Basic coding and I need some help with an error I'm getting. I'm trying to pass a structure array to a function to figure out a student's grade. I'm getting the error that 'QuizOne' is not a member of System.Array. Here is my code:

ive two custom controls, which are used to draw and edit etc...(like paint but customized....) i want to save their images with a single click....So im using the Getimageofcontrol function to do it....its code is below:::
Public Function GetImageOfControl(ByVal c As Control) As Image
Dim rc As New Rectangle(c.PointToScreen(c.Location), c.Size)
Dim i As Image = New Bitmap(rc.Width, rc.Height)[code].....
and the code to call this function for saving the images is simply.. ...
GetImageOfControl(pboxd).Save("c:78.jpg")
GetImageOfControl2(pboxf).Save("c:lp.jpg")
but the problem is that both the images have the same content....

I need to display images when I press a key on the keyboard. I have a form with a textbox and a label on it. When I type a letter in the textbox it appears on the label. I got that part to work. But now I want to display a image in the label when I press a key on the keyboard. I have found some images on the internet that I want to display when I press a key on the keyboard. For example when I type the letter A in the textbox instead of A appearing I want an image of an apple to appear, or if I type the letter B a banana would appear, or if I type the letter D a dog would appear. I have been searching on how to this I came across the keyboard event such as the keypress event. Can I use a keypress event of the textbox to do this. Can I assign a certain image to a certain key on the keyboard, and have that image display whenever I press that key.

View 8 RepliesI am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.
value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.
Shared Function CompareArray(ByVal FirstArray() As Object, ByVal SecondArray() As Object, Optional ByRef ErrorMessage As String = "") As Boolean

View 5 RepliesHow do you create an array for images, specifically to develop a slot machine game so-to-speak. Because our class is using a really, really old version of Visual Basic (that is, VB 4.0...ick), I decided to move myself up in the ranks and play alongside and learn the newer software.I've mentioned arrays before if you recognize my screen name, but situations caused me to bump up again to 2010, so now I need some help reacquainting myself with the software.

The above coding correctly loads images into an array of 10. I'm looking for a way to upload all 10 of them using ftp.I have only found a way to do one file at a time, but I want to loop it or something, and I can't get that to work.That FTP Upload coding errors on the line: I don't know why, but it correctly converts an image using ImageToByteArry conversion, yet it loads nothing into the byte, so it errors.
I dragged and dropped a label control on my web form. But then whe I go to my VB .net code behind file, if I try and set a property on that label control, I am getting a "Declaration Expected" error message for the label I created.Yet if I do try and explicitly declare my label control, the compiler tells me that the label control is already declared.[code]

View 4 RepliesI'm trying to make a Blackjack game in VB. What I'd like to do is populate an array with each of the cards so that I can randomly generate integers and use those integers to pull an index from the array, basically randomly selecting a card. My problem is that I can't seem to get the images in the resources folder to go into the array. I'd like to use a For/Next loop to populate the array, as I would rather not manually assign all 52 cards to the array. I'm trying to do it like this:
Dim CardArray(51) As Image
Dim LoopIndexInteger As Integer
For LoopIndexInteger = 0 To 51
CardArray(LoopIndexInteger) = My.Resources.ResourceManager.GetObject(LoopIndexInteger)

In my VB code behind the aspx is it possible for me to call a function based upon a click on a string format.e.g.
Sub testSub()
Do Nothing
End Sub

Then add my stringtoUse to my control. So that on my control I have two words Hello which when clicked goes to my hyperlink and World which when clicked calls my function/sub.
Well, its not text, but a number. I've currently got about 10 labels and right now I'm checking each one of them separately using if statements, but I've been told that there is an easier way using a For statement (I've never really got used to it...) to check all of them without having so many if statements... Currently I'm trying something like this (which, ofcourse, doesn't work and is completely wrong :X)
Dim i(10) As Integer
i(1) = label1.Text
i(2) = label2.Text

I'm really really rusty/rubbish at this, but I have a series of 11 bitmaps in my resources folder.
I'd like, each time I click a button, a different image loads in sequence into a picture box. How do I do this. I know I've got to some array which loads the images, and a loop to increment through the array, but I can't put it together with the resources folder and the PictureBox control.
I sort of got something like this:

I'm trying to validate a form to be filled out by the users, and when the required section isn't filled, I increment an
ErrorCount += 1
variable to show that error(s) have occurred inside the program, I then also set an
ErrorArray()
to whatever the corresponding field number is, now I have 0-12 (13 fields). What I have also done is titled the labels that are associated with all of these fields to correspond with the ErrorArray() value that might be set, such as.
PatLabel0
PatLabel1 etc.
What I am trying to do is loop through the array contents, depending on which ErrorArray() values have been set, to go and set the corresponding fontcolor property of that label to red, to show that these now need to be filled out. This is what I have, but Visual Studio doesn't allow me to use the iteration through the loop as a reference to changing properties. Can anyone point me in the right direction to trying to figure this out, or at least tell me what else I could do. Just seems doing 20 if....then....else.... statements with 2 - 3 lines in each of them is redundant when 1 function line could do the same job. This is what I have.
for i = 0 to UBound(ErrorArray(12))
if(ErrorArray(i) = "*")then
PatLabel(i).forecolor = color.red

that is basically all im looking for initially, but I can't do it.
