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.
View 1 Repliesi'm working with visual studio 2010.I need to read out the resolution from a MPEG file. So that would be the video width en height.I think I need to create a button linked to an openfiledialog.show(), and then get a property from the specified file, by passing it on to a function.My question: Does vb.net has build-in methods to gather the property of a file? Or does one know a free com component that does it for me?
View 1 RepliesI'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 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

Private Shared Function GetWindowRect(ByVal hWnd As IntPtr, ByRef lpRect As Rect) As Boolean

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 just installed Microsoft Ribbon for WPF 2010 on 2 different windows 7 boxes. If I make a .net 3.5 project it works fine but a .net 4.0 it does not.I can load the sample ribbon application and it works but when I drag the ribbon controls over they just make a transparent box. I notice it does not make the XAML correct. Here is the code, 4.0 on top then 3.5 below it. Is there some setting or option I need to change?
<ribbon:Ribbon Height="136" HorizontalAlignment="Left" Name="Ribbon1" VerticalAlignment="Top" Width="618" />
<ribbon:RibbonGroup Height="100" HorizontalAlignment="Left" Margin="72,36,0,0" Name="RibbonGroup1" VerticalAlignment="Top" Width="200" />

I was wondering if it is possible to use the WPF Ribbon in windows forms(they added it in .net 4). I know about the ElementHost Control which works fine for created controls, but it doesn't seem to be able to host default controls, I could create a wpf control and put the ribbon in, but that seems like a terrible hack.(And lots of work since there are lots of controls related to the ribbon)

What I am trying to do is fill the contents of the datagridview with the cell contents. There are two ways to do this.
1) Either set the DGV width to the cell contents width, or
2) Autoadjust the width of the cells to the width of the DGV.
how to implement either of these two approaches?
This Winforms app has a toolStripComboBox within a MenuStrip container that displays Culture Info languages.The toolStripComboBox's width is not expanding to accommodate the size of the string. The strings are dynamically added to the combobox from underlying code. How do I get the comboboxe's width to expand? Below is an image of the'too narrow' combobox and below that the Properties for the combobox.
View 1 RepliesIn VB.NET for the combo box, I have set the autocomplete mode to "SuggestAppend" and autocomplete source to "ListItems". Its working as expected. But the width of the autosuggest dropdown box is not same as that of combo box and so it looks weird.I tried changing the value dropdown width property but it changes the value of normal dropdown box (seen after clicking down arrow on combobox), and not the autosuggest dropdown box.So what code or property needs to be set to make autosuggest dropdown box the same width as that of combobox width?
View 1 RepliesI have a drawing program written in VB6 that is capable of printing very thin lines to a laser printer. In VB .net, even though the pen width is set to 1, the thinnest lines are way too "thick". The equivalent line width in VB .net using a pen width of 1 is about the same as the DrawWidth = 4 in VB6.

There's a picturebox with the captured screenshot and when he clicks on the picturebox, I have to grab the width and height where the user clicked. This is not the width,height from the whole screen but from the picturebox.
I'm loading a picture into a picturebox. How can I set the pixel width to a fixed number, ex 300?
The whole picture must fit the picturebox, even if the original resolution is higher.

bmp.SetResolution(300, 50)
PictureBox2.Image = bmp
Is there a simple way (without measuring characters using a Graphics object) to check if a font is fixed-width?
View 7 RepliesI am creating a puzzle game and would like to calculate the width and height of the puzzle taking into account the original image size and the screen resolution. My screen height is 768 and width is 1366. An example image is 1200 x 1600 and the jigsaw size that works well with this image is 480 (height) x 640 (width). I would like to create an algorithm that calculates the jigsaw size for any image bearing in mind that the screen resolution will change as will the size of the image.
View 2 RepliesI have a databound DataGridView, and I'd like to keep one column in front, with a slightly smaller width than the default. The grid's AutoSizeColumnsMode property is set to Fill so that the columns fill out the entire grid. This makes the first column equally large as all others, which is why I need to set its width manually. The smaller column is the first one with the checkboxes. I have two grids that I need to do this with, and for some reason it works just fine with the first grid, but gives a null reference error on the second grid...
Here's the code for the first grid (working fine):
vb.net
Public Sub UpdateTodoGrid()
' Load todo items
todoGrid.DataSource = _TodoManager.LoadAll()
' Set backcolor
For Each row As DataGridViewRow In todoGrid.Rows
[Code] .....
As you can see, the code is exactly the same (except for not setting the BackColor of each row and not using the ReadOnly property*). When I run this code, it gives me a null reference error ("Object reference not set to an instance of an object.") on the line where I set the column's Width. Obviously 'col' is not Nothing (otherwise it would have errored before that line), and there's nothing else there that could be Nothing... I assume that something happens internally in the grid when you set the width of a column, and that there is a null reference there, but obviously I have no control over that.
The grid's are absolutely the same, as the second grid is just a 'copy' (meaning I copy/pasted it in the designer) of the first. So all their properties are equal. I thought maybe the ReadOnly properties were the problem, but I tried putting them in in the same way and the issue did not go away... The first grid is not ReadOnly (because the checkboxes need to be editable), but all rows except the first are, while the second grid is completely ReadOnly.
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.

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
