I have to Panels on a Form. The "upper" Panel is set to Dock = Fill the second "down" Panel is set to Dock = Bottom
Ok. - During the application I add some usercontrols in to the "down" Panel.
Now in one of the usercontrols, I have two group boxes (also set to Fill & Bottom) In the upper groupbox (Dockstyle = Fill) There is a Grid and below the grid, I have two RadioButtons.
On my developer machine, I can see the Grid and the Radiobuttons. On an other machine (other resolution, and other Display), I have the problem that, the RadioButtons are not visible anymore. - The user has to change the height of the "down" Panel by hand, so he can see the RadioButtons.
What I try to do now (and I don't get it working) is: Set the minimum heigt of the "down" Panel so, that both Groupboxes are visible and what is more important: that the commands are all visible.
calculate the height of the grid and the Radiobuttons depending of the solution and used display!?

View 3 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.

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?

ListBox1.Visible = False

View 39 RepliesI have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I have been looking for examples to find the string between two strings. This top one works fine;
Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)
[Code].....
Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?

Is there an easy way to find a certain string within a string and then return the strings that you find as an array?I have written this:

View 2 RepliesI have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

View 1 RepliesI have a custom control that includes a DataGridView control. I would like to be able to adjust the heights of the rows on the dgv to fill the custom control on the target form whenever the custom control is resized. I am able to adjust the width of the various columns so that the dgv fills the custom control, but I have not been able to adjust the row heights in a similar way. I have tried the following code in the resize event of the custom control
for i = 0 to dgv.columns.count -1
dgv.columns(i).width = newwidth
next i
[Code]....
This doesn't cause an error, but the code does not change the row height. The column width change works fine.
I am able to change the row height by changing the font size at custom control compile time. I have not tried to change the font size at runtime, since this would not achieve what I am trying to accomplish.
I suspect that my problem is that I have not set one or more of the autoresize flags properly, but I have tried all the combinations I can think of.
