VS 2005 CurrencyManager.Position += 0 ?
Dec 17, 2009
what the purpose of the following code is:[code]....
What it does appears obvious: it increments the position by 0 (i.e. leaves it unchanged) so it appears that it does nothing-but the vendor included it so I'm assuming there's a reason.From the comments, MyCurrencyMgr is the CurrencyManager for the 'primary table' and the CurrencyMgrCollection should contain CurrencyManagers for 'other tables' but I can't find where any are actually added to it-and whether the other CurrencyManagers exist or not, I still can't see what the purpose of this code is.

I'm starting to learn about using the CurrencyManager to change the position of data and seem to be missing something because the postion is not changing. look at this code and let me know what I'm missing?
I hard coded the postion in:objCurrencyManager.Position = 1 and used the debugger to step through the code to see what .Position is holding and after the statement executes, the value is still 0 even though there is data in the dataset. I was hoping the textbox would display the data from the dataset located in the 2nd row of the dataset but the position never changed.

When you select Definition in VB6.0 there is this Last Position menu that lets you return to the line where the cursor is located previously, it seem to be missing in .Net IDE or I can not just find it?

I'm testing a small program that can read & write to an rtf file. Examples I have found work fine, although I have two questions:
1)If I need to ALWAYS write to line number 9 of an existing RTF file, do I need to "read" 9 times or can I immediately position myself to line number 9. I have found character manipulation but can't seem to find what I need with positioning to a particular line number.
2)BOLD text: I have found examples where I should be able to format my text, such as
MyFile.WriteLine ""
MyFile.WriteLine Text
MyFile.WriteLine "0"
but when doing this, it does not "bold" my text, but actually prints the text exactly as shown. I'm looking for information/links that I can "bold" "Italicize" text. Code is written in VS2005.

Can anyone demonstrate with an example how to shift the position of a datacolumn in a specific position after it is added at the end of a datatable.For example lets say I have a datatable with 9 columns and 5 rows. Now I added a 10th column. However I need this new column as the 5th column which requires shifting. How do I perform this shifting?

I have a bunch of PNG images in my project's resources. I need to find out whether the pixel at any X,Y is transparent or not. Testing the alpha of the color returned by GetPixel doesn't work, and I can't test it against the transparency key because Bitmap objects only have a MakeTransparent method, for some strange reason. Is there a way to tell?

I am trying to get a picture box to update with a new picture when I type in a number in the navigator position item box and hit enter. I have tried various methods, but I can't seem to get a combination that works in this way. Could anyone tell me if what I am trying to achieve is possible, and if so
This is the latest variation I tried (yeah, I know...) :
Private Sub BindingNavigatorPositionItem_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BindingNavigatorPositionItem.ModifiedChanged
Dim Picture As String

** note that the <fileLocn> is just truncated for the purposes of this post - it does actually have proper code, so that isn't the issue!

Very simply, I'm positioning a small ListBox over a DataGridView column when the user right-clicks and selects "Show Distinct Values". This works fine until the vertical scrollbar of the DataGridView is clicked. Once that's done the listbox pops up all the way over to the left edge of the DataGridView. As confirmation of the problem I created a small app to test with.

What I'd like to do is position Form2 underneath the Label on Form1 when the "down arrow" button is clicked. (Basically Form2 should have the same "Left" as the Label on Form1, and its "Top" should be the Top of Label1 plus the Height of Label1.) Please see attached images for further clarification. (I did something like this in VB6 with the SetCursorPos API and the Screen.TwipsPerPixelX and Screen.TwipsPerPixelY properties, but I'm sure there is a better way to do this in .NET.)

Here's the issue in a nutshell (I can elaborate if you feel it's needed). In a DataGridView I want to capture the value of the row's key column so that when the user clicks on a column header to sort the data, I can reposition to the row that was selected prior to the click. The problem is that the sorting itself, once it's done, fires the same events (RowEnter for example) that I used to determine my key value, so it sets my variable to a new value and now

What can I replace this line with? I have read on the internet that since my application should be web-based, I cannot use the Windows namespace. I think what I am asking for is a pretty simple solution, but I am a very new VB programmer. More of my code below.

I 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?

I 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)

I 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.
