View 6 RepliesDoes Visual Basic arrays have the possibility to assign values in one line?i.e. No need to have a loop to assign a value for the whole array.for example,
Dim Array1 (1000) As Integer = 478
Dim Array2 (1000, 1000) As Integer = 852
this means that all values of array1 will be 478 and the other is 852.

View 4 Repliesso i have 101 pictures and i need to assign the pictures to an array so that i can do a for loop to generate them all.
so what i have is 101 pictures in my resources, and i have a array of 100 (Pictures(100)) and i was thinking if there is a default value to the resources so i can maybe do something like for i=0 to 100 pictures(i)=my.resource.i <--- assuming 1 is default value of the resource. folder but it isn't just saying

View 37 RepliesAfter 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 RepliesSo if I create an object test, and it has a property color. When I add this object to an array list I typically can access this using myarray(0).color but intellisense doesn't 'know' that I have a 'test' object inside the array. It would let me type myarray(0).whatever but would then crash if I made typo. It seems like I should be able to let it know what type of object I am trying to work with inside the arraylist. In code maybe something like this

In VBA / VB.NET you can assign Excel range values to an array for faster access / manipulation. Is there a way to efficiently assign other cell properties (e.g., top, left, width, height) to an array? I.e., I'd like to do something like: Dim cellTops As Variant : cellTops = Application.ActiveSheet.UsedRange.Top..The code is part of a routine to programmatically check whether an image overlaps cells that are used in a workbook. My current method of iterating over the cells in the UsedRange is slow since it requires repeatedly polling for the top / left / width / height of the cells.I'm going to go ahead an accept Doug's answer as it does indeed work faster than naive iteration. In the end, I found that a non-naive iteration works faster for my purposes of detecting controls that overlap content-filled cells. The steps are basically:
(1) Find the interesting set of rows in the used range by looking at the tops and heights of the first cell in each row (my understanding is that all the cells in the row must have the same top and height, but not left and width)
(2) Iterate over the cells in the interesting rows and perform overlap detection using only the left and right positions of the cells.[code]
I have 22 images and I am trying to add them into an array and then assign them randomly to a button so when the button is pressed it will change to the assigned image. Also is it possible to randomize the array.

ev.Graphics.DrawString(ROData(x, 3), PrintFont, Brushes.Black, LeftMargin, Ypos, New StringFormat())

The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.

I have noticed that when iterating DataGridViewColumns, the speed is greatly reduced if the columns are visible.
For Each col As DataGridViewColumn In cData.DataGridView.Columns
col.Visible = visible
Next
If visible is set to false (and all columns are all currently visible), iterating 264 columns takes around 0.35s, however, if visible is set to true (and all columns are currently invisible), the same process takes around 30s.Does anyone know what would be causing the extra time?Could it something internal to the DataGridView Control?
