VS 2010 Dimensions Of A Window With API?
May 15, 2011
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.
vb.Net
<DllImport("User32.dll")> _
Private Shared Function GetWindowRect(ByVal hWnd As IntPtr, ByRef lpRect As Rect) As Boolean
[Code].....
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'm making a photo editor and the size of the image depends on the size of the window, like the Zoom mode in the BackgroundImageLayout property of a form. It works sometimes: when resized only a small amount, it does nothing, but when the image is resized more than that, it jumps to the right position.
vb.net
Private Function GetImageRect() As Rectangle
Dim r As New Rectangle()
If Me.ClientSize.Width > Me.ClientSize.Height Then

I am writting a program that aims at filling up bookmarks of a template with data retrieved from a sql server db. The form opens a Word document but I can't control the position and dimensions of the word document. It seems that I can't manage to overwrite MS Word default settings for position and dimensions. I want to be able to display the word document close to the form.Here is the code that I have tried and doesn't work:
Dim

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 creating a ribbon for an Office application using VB.NET in Visual Studio2010. I drag an edit box onto the ribbon but am unable to resize it. How would I do that? I want the user to be able to enter and see up to about 20 characters. StringSize does not do the trick.

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

Public Sub LoadFromFile()
Dim sr As New StreamReader("CoverageArea.dat")
Dim strAreaLine As String[code].....
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 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

Knowing this, is it possible to determine the size that a character will be exactly if I know the character and all the information above? I have to draw them to bitmaps that are the same size as the character and no bigger.

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.

I'm reading a folder to assess the width x height of jpeg's, to classify them in various ways. Opening each as a bitmap and reading the bitmap width and height works but of course is laborious and very slow .... I've read various JPEG file format papers but retrieving the image pixel width and height seems none too obvious. Is there a logical way in VB to get this info quickly? My jpeg's are bog-standard ones made using VB's "Bmap.Save(Fname, ImageFormat.Jpeg)".

I'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.
