Array Dimensions - Error Message 'ReDim' Cannot Change The Number Of Dimensions Of An Array?

Oct 20, 2011

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 have a MDI form that has a child form that is opened by default when the application loads. I also automatically maximize the child form. Even though I have set ShowIcon to false, the little blank image that indicates that there is no icon appears in the upper left hand corner of the form. Is there a way to get rid of this?

Set The Viewable Area To A Smaller Screen Area?

Jun 11, 2012

Trying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.

Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000

[code]....

Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.

Specify Actual Usable Form Area Instead Of Outside Area?

May 12, 2010

I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

Can't change the contents of Class A, B, and C

.net - Parent/Child Relationships Failing When Getting Data From Parent Class With Multiple Forms Open?

Jun 24, 2009

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.

dim l = Mainform.subform.listofdata

Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this

Protected Friend frmMain as Mainform
frmmain = new mainform

In frmMain I am doing this

Protected Friend frmsub as new Subform'
frmsub = new subform

Comparing Two Arrays With Different Dimensions

Mar 9, 2012

I 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
Is there any way of doing this for older version of .net framework without using Enumerable.Except

Define A 3 Dimensions Matrix With Different Data Types?

Dec 8, 2011

I define 3 arrays: ID(n), Hour(n), Showed(n). If Hour(i) = actual time, I get the data pointed by ID(i), if not Showed(i).

BUT... I can add new hours or modify some existent, but I need to have the Hour array sorted. If I sort this array, the ID and Showed will point to different data.

So I though some different solutions:

1 - To make a string array with all inside (a 7 characters ID, a 5 characters Hour and 1 char for showed (T or F)). It could work, but, how can I sort the middle part of the array (Hour)? So, this don't work.

2 - A 3 dimensions "multitype" matrix (1 dimension of type Integer, the second of type Date and the third of type Boolean). I have no idea about how this can be done.

3 - A 3 dimensions string matrix, some like the "all inside" array: ID converted to a fixed size string, hour converted to a 5 chars string (hh:mm) and Showed converted to T or F. And sort the second dimension.

4 - Sell my copy of Visual Studio and drive a taxi cab

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).
