I have a question about that strAreaInfo()...I left the () with no number in it so that it wouldn't have a set # of values, and then I tried to give it 3 values, but I get the error in the title. Am I doing something wrong when I declare it?

I'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double()
Dim i, j As Long
Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.
I am trouble in sorting 2 dimensions array in vb.net. One row has 5 columns. Original array have 3000 rows.How can I get the effective sorting with pdtId. I tried to find googling, cannot get the right answer to me.

(0, 1) = brand name
(0, 2) = category Id
(0, 3) = url
(0, 4) = date

I wounder if there is a way to get the values from array's dimensions, without knowing how many dimensions the array has.I know how to do if I know the array's dimensions, but not a clue if I don't

This statement works fine in ASP, but when I switch to ASP.Net, it give errors 'ReDim' cannot change the number of dimensions of an array.
After user entered a value into textbox (for example 4), datargidview must be create automatically(number of datargidview's columns and rows must be textbox value). And, user enter some values that among 0 and 1 into datagridview's cells. So i want to assing these values (values that are written in datgridview cells). For example, if user enter 0.25 in datagridview's cell 1, and 0.34 cell 2, 0.67 cell 3, and etc, in this instance array(1,1)=0.25, array(1,2)=0.34, array(1,3)=0.67 must be assigned. i hope, i could understand :) i illustrate this example below. i want to assign such as indexs that is written into following example table.
View 1 RepliesI have this recently converted application from vb6 to vb.net 2008. One of the errors stated is:'Point' is not a member of 'System. Windows. Forms. PictureBox'.I have searched and not found an alternative to this.Also, it says ReDim cannot change the number of dimensions in an array.
View 8 RepliesI'm trying to write some of my own linear algebra methods, and I'd like them to work independent of the number of dimensions of the array. However, there doesn't seem to be any generic method, that I can see, for looking up a particular element in an array of arbitrary size. I mean I could write code to find the rank and then use (), (,), (,,), (,,,), etc, but that seems rather cumbersome.

I have figured out how to populate the comboboxes for an app I'm making from a database this is not the actual code but is basically the way I'm populating them for i = 0 to maxrows - 1 cbobox.items.add(dataset.tables("datatablename").Rows(i).Item(x))next i need either to be able to manually assign an index value to each added item or at least figure out how vb.net manually assigns index values to these.
View 1 RepliesI am trying to compare two arrays that always have different dimensions.
e.g. arr1 -> {1,2,3} and arr2->{1,2}
I did try and able to get the matching items to new array. But I am expecting to get the unmatched items only. I am expecting to compare both arrays and put only the item '3' to a new array which is in arr1 and not in arr2
e.g. arr1 -> {1,2,3} and arr2->{1,2} should result a new array with 3
arr1 -> {1,2,3,4} and arr2->{1,2} should result a array with 3,4

i have found the Hwnd for a window and i now wish to get information about this window, the location on the screen of the window and its width and height. Problem is the values i get are not anything near right.

this returns 0 for height and width and the remaining figures are nearly 0 (1.68E-311) what am i missing and how can i get this information?
I have a listbox and I want to loop through each of the items to see if the string im looking for is inside. I know I could do .contains but that wouldnt look at substrings. The code im using looks like this:
While tempInt > Listbox.items.count then
if searchString.contains(listbox(tempInt)) then
end if
tempInt+=1
end while
Everything in the loop is fine but VB gives an error on the listbox(tempInt) part. The error is "class windows.forms.listbox cannot be indexed because it has no default value". get around the default value crap? I tried putting in a blank string but no change.
is there a way to change the user's screen dimensions. like change to 600x800 resolution

I'm working on a small game that is based on a map of grid squares.I have a class (clsGrid) that stores a few properties for each grid square.The grid square objects are organized into a list(of clsGrid).A loop and stream reader are successfully reading properties from a text file, putting the properties into grid objects, and adding the grid objects to a my list of grids. When retrieving a grid from the list of grids, I'm getting unusual results. Regardless of the index I give the list, I always seem to get the last indexed grid in the list.The debugger seems to suggest that the right numbers are being read into the stream reader and they are being added to gridHolder. However, the message box at the end will always show me the LAST grid.id, regardless of the index I give it.

I have a form with a lot of PictureBoxes. I created an array of these by name, but when I index the array I cant assign an image to the indexed item. In fact all the indexes appear to be nothing. Is there a way to create an array of controls and access them from the array?
