How can I re-created this in VBA
I need to define a property in my class which is an array (of doubles).My original (bad) version is this:
Public Class Market
Property Correlations0 As Double
Property Correlations1 As Double
Property Correlations2 As Double
[code].....
This however doesn't work. I get an error already at design time: "Public Property Correlations as Double has no parameters and its return type cannot be indexed."What should I do with it? I also do not know in advance how large the array should be (the array size is determined at runtime based on other properties).
Is there a way to define an array inside of the sub call parentheses?
Private Sub sub_name(byval sString, arrString)
sub_name("Some Text", array.{"","",""})
What I've been doing is passing a string and using a split on it to break it into an array in the Sub/Function, but I was wondering if there was a way to make the array inside the parentheses. I've looked through Google, but I'm guessing I'm not asking the right questions or it's not possible.
I have a form that contain 30 image (load by array) and when one of the image clicked, the background of my frmMain should change to the image clicked. The program has no problem by launching the code below :
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picWallpaper1.Click
frmMain.BackgroundImage = picWallpaper1.Image
End Sub
Private Sub PictureBox2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picWallpaper2.Click

But this way is not effective if I want to increase more image up to 50,60 in future the program will loaded with these code.
I'm developing a class in which most of the properties need to be updatable, but also protected against being inadvertently updated. I've got some code that does this, but I'm not happy with it. What I have is:

I'm having trouble passing an array of a user defined type to an procedure in a COM DLL. The prototype for the procedure i'm using is this:
HRESULT STDMETHODCALLTYPE GetData(
/* [in] */ DWORD dwCount,
/* [size_is][out][in] */ CSimData *puData) = 0;
CSimData is a structure which is also defined in the interface.
I'm trying to call it with the following code but am getting an exception:
Dim temp(1) As MACHPLANTSIM18Lib.CSimData
temp(0) = New MACHPLANTSIM18Lib.CSimData
temp(1) = New MACHPLANTSIM18Lib.CSimData
[code]....
The exception i'm getting is "COMException was unhandled - Exception from HRESULT: 0xC0000005" It looks to me that the array isn't passing properly to the COM function. I'm able to send a single object, but when I do an array of objects I get this exception.
I have populated an array.
Button1 click event
Dim array1 (3,3) as string
array1 (3,3) = "BLA"
End Event
Now, in the same class, I have another button.
When I click on this button2, i want to use this array to stream files to textfile.
The problem is that I cannot pass data from button1 click event to button2, as I have to declare the array again, and that causes array to lose data on button2 click.
If I however, declare array on top of class, I get a funny error sying out of index range etc.
i have a array like below. Dim sTemp() as string={"CCC1", "CCCs10", "CCCx11", "CsCC2", "CffffCC3"} I have to sort this array depends on the prefix(nymber)

View 4 RepliesI have an application that basicly collects a lot of information on a form, with 5 seperate tabs, prior to outputting this to a text file. Currently the forms are not dynamic in that they contain all the possible texboxes and just hide or show them depending upon choices made. The data is gathered by a function that creates an array of texboxes requiring processing, array being created would seem to correspond to a single line that is being output. The array is moved through item by item and the data gathered then output as a line in the text file. This is repeated for the 80 odd lines. Now a couple of questions, is this the best way to do this?
