View 2 RepliesSaving Window Size And Position Multiple Monitors Toolbar Position Etc.
Aug 24, 2009I have looking for a tutorial or class that demonstrates more than a trivial example of saving a windows position on closing. The ones I have found don't seem to work on all systems because of:
1. Multiple monitors. (and resolution between those monitors)
2. Toolbar size and position (toolbar is only on the primary monitor, well sometimes)
3. Sometimes the programs dont open on the right monitor they were closed on.
Is there an extensive class or tutorial on all the stuff a programmer needs to get right to have a window size and position persisted between executions?

View 39 RepliesPrepend A String To All Strings In A List Of Strings?
Aug 5, 2010I 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.
VS 2008 Using List Of Strings Or Array Of Strings?
Oct 16, 2009I'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?
Get Closest Position To Specific Position?
Mar 9, 2010I also have a function that returns ALL tiles on the map and they're X, Y position. How could I find out which one is closest to the position I specify? I can't figure out how to go about it. how to implement it with this. Heres a MADE UP example if what I'm trying to do:
Dim MyPosition as New Position()
MyPosition.X = 400
MyPosition.Y = 400
Dim tList as New List(Of Tile) = MyMap.GetTiles
Now, I can already do the stuff above, but what I need to make is something like this:
tList.GetTileClosestToPosition(MyPosition)
Find Strings Inside Strings?
Aug 15, 2011I 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?

View 2 RepliesDataGridView - Convert Nulls To Empty Strings And Display It In The Grid As Empty Strings
May 14, 2009I 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

Setting Start Position For A New Form To Another Form's Position
Mar 24, 2010I have two forms: Main and Options.Main can be moved around the screen (like a normal window).When the user clicks a button, the Options form opens up and the Main form HIDES.How do I set the Options form to open in the exact place that the Main form was last on the screen (to give it the effect the MAIN form never went into hidding)I was thinking to set Option form's StartPosition to Main's current position, but I don't know the syntax for that or if it's even something you can do.

Getting No Row At Position 6 Error
Sep 13, 2009I am getting the error there is no row at position 6 but there is data at position 6. May I know if there is any better way apart from this that will "see" the correct number of rows in the database and display out the correct rows in the database? So lets say you have one row auto - increment and one column containing the data. Currently now if i delete off the row no 6 and add back the row, the dataset cannot see this row anymore thus giving me the error, there is no row at position 6.
If i take off the auto - increment row and test this method out, i get the same error.

Interpolate A Z Value For A Known X,Y Position?
Jul 7, 2010Given a set of X,Y,Z data points, how would I interpolate a Z value for a known X,Y position? Are there any methods built into .NET to accomplish this. What algorithm could I use?
For example, say I have a graph of X, Y, Z data, and I know the cursor's position. I can find the four closest real data points. I would like to interpolate the z value for the X,Y position of the cursor.
Here is a dummy data set.
(x,y,z)
(-4, -2, 700.065);
(-4, 0, 932.907);
[Code].....
If the cursor was at (.3,.5), could I use the four closest real data points (0,0), (0,2), (2,0), and (2,2) to find the interpolated z value?
