Im looping through a datagridview and there are times when I need to pause it and then start right back up where left off. How could I do this? Maybe get last row that it stopped on then continue on next row or is there something else to better accomplish this.

I would like to know how to loop with textboxs. For example. I would set the text to "Hello" And the loop will send this...
-"Hello1"
-"Hello2"
-"Hello3"
I have tried many looping techniques but they all used listboxs and even modifying them I could not get it to work correctly.
I have this Visual Basic class I'm taking online. At this point in the section all I'm supposed to know about are Do, Do While, Do Until, Exit Do, Continue Do, and For Next loops. So try not to go off in a fancy super-coder direction. And everything is (preferably) made through Console Applications on VBE 2008
Problem 1:
Write a program that evaluates the factorials of the integers from 1 to 10 using an appropriate data type. (factorials are... factorial of 1 is 1, factorial of 5 is 120, or 1*2*3*4*5=120)
Problem 2:
Make a diamond - 1 asterisk at the top, 9 asterisks at it's widest - using only nested For...Next statements to print the asterisks AND spaces, minimizing use of output statements.

Have this Uni question; which after 20 minutes of frustration I'm sending it to the brain trust (you might be interested).Write a program that, when a button is pressed, checks the contents of a textbox. If the textbox does not contain a number, the program informs the user of this and does nothing more. Once a number has been entered, the program will do something trivial such as displaying double the number in a message box.Notice that this can be done without explicit looping,even though the user might repeatedly enter non-numbers. Because it is an event-driven program, each iteration is started when the user clicks the button. The looping is driven by the user, not by a looping statement.

I'm using this code to get the preview window
Dim iHeight As Integer = picCapture.Height
Dim iWidth As Integer = picCapture.Width

' Open Preview window in picturebox

As you can see, I have 2 sources. Would it be possible to not show the preview window, but instead loop through all the sources?
That would be in a timer, so like each 10 seconds a pictures is made from each source.
i have a winform and i have about 30 labels and 30 picture boxes on it. What i would like to do is fill each label and picturebox with a value and image from a backend database. I could have easily done this in vb6 using control struture , for eg.
for x = 1 to 30
picturebox(x).image = value from database
label(x).caption = value from database

But that is not important this moment... How would I set a code too use the progress bar? So As it loops at a certain rate {Lets say 1000 (1 sec)} It would show the progress. Currently using it to 1 - 50.

The code below shows me (I think) that the "for each" loop is about 10% faster than the "i to n" loop, but the "for each" loop creates 567k in new memory? Is this right? Which way is generally most efficient with regards to speed and memory usage? If you want to run this code in VB just add a button and 2 labels to a form.
