I found this but to no avail:[URL]..I have generic fields and labels that I put inside already predefined table layouts. Some fields need to span rows/columns and I can't figure out how to do it within code (aka not in the designer).

Lets say you pay $900.00 for the first invoice in this list. How do I zero out that balance, AND carry the remaining $30.00 to the next invoice ($730.00) and subtract from it.

I have a datagridview and I'd like to write it to a file in the same type of row and column format it's currently in.My first idea for doing this is to get the maximum number of characters in each column so i know how wide each column has to be formatted. Then loop through each row and write out each row while using the max characters in each column and the current cells content length to do the math to get the formatted columns to line up. Like the example below, except i'd have a lot more in it.
writer.WriteLine("{0,0}{1," & lb(2).Length + 50 - lb(1).Length & "}", lb(1), lb(2))
This takes label(1) and label(2) and writes them so no mater the length of either (to an extent) then will always be right hand aligned in two columns.
I'm working on a project. Part of the project needs me to capture data, for example, email address, from certain rows/columns of a datagridview and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). I am familiar with doing these in web form but windows form are different and i am not familiar with it.

I had a number of userControls added to a tableLayout, what I want to do is dispose of all userControls however if I use the following code it only seems to dispose of the first userControl and not the rest:
For Each myControl As userDisplaySet In Me.tableDisplaySet.Controls
' Closes control
myControl.Dispose()
Next
I've got a Panel on a main Form containing a PictureBox control on Top of a TableLayout control. Both the child controls have their docking properties set to Top. The Picture control has sizemode set to Zoom.
What I'm finding is that the picture doesn't size properly when I start the app. There is a border at the top and bottom in the PictureBox control. It's only when I resize the overall form that it's correct.
So at the moment I've got this ugly bit of startup code, just to fix the problem Me.WindowState = FormWindowState.Normal Me.WindowState = FormWindowState.Maximized
What am I missing?
My code was working fine when I tried with 3 columns. Now, when I mode columns (13) it throws the error.
