I'm making an art program involving 8x8 squares on a grid, but there are 64x64 grid square PictureBoxes for each grid square. Meaning there are 4096 picturebox squares to be setup.
I'm having them names like pic0001, pic0002, pic0003, etc... but re-naming them individually would take me forever. Is there a way to mass re-name them at once?

I have a website that has 20,000+ members and i want to send each member a personalized admin update emails.I am currently sending about 200 emails at a time. To send to all the members, it takes me a few hours to complete.This is what I am trying to figure out how to implement.How can i possible build a webservice or something to send all these emails in the backgound at set intervales or something so I don't have to sit and click a button each time to send the emails out?I have seen many opt-in email list sites that when sending email, you get a page that the email was sent to the queue, and i receive an email back when the sending of all the emails is completed. This is something that i want to implement.

View 2 RepliesThe code below updates all cells in a DataGridView column to a value from a textbox. This code works in that all cells in the desired column are updated on screen. The DGC is bound to a dataset. The problem is that when I call the dataset .Update method, sometimes the first row (row 0) does not get updated. I have run SQL profiler and can see that no SQL update command is submitted for the first row. The first row only gets skipped the first time the update is run after launching the app. Subsequent updates run for all rows, until the app is re-launched.
I have verified the row state is Unchanged with: Msgbox(DataGridView1.Rows(r).State.ToString).
The 2 commented lines below are other things I have tried that still cause the first row to be skipped.

how to read files from an USB mass storage device. I have found plenty of posts regarding drive letter detecting and reading the files. It's OK, but what about a device, where no drive letter is assigned - e.g. my mobile phone is visible under "My Computer" as "Mobile Device". The same situation it with my MP3 player. It's visible under "My Computer" as "Sansa device". Please, could anybody help me? I need to enumerate USB devices, identify, which ones have a file system and finally, I need to read/write a file to the file system.

I am working in Visual Basic 2008 and am trying to create an application that calculates body mass index. I have the entire form complete as well as much of the source code, but I am having trouble creating the code for input validation. On the form I have a text box for entering weight and a text box for entering height, which are both used to calculate the body mass index. Therefore, both text boxes input information cannot be negative or an illegal character ( $, @, !...) The input validation is supposed to present a Message Box that displays something along the lines of "Please enter numeric values" when input values are illegal characters "Please enter a positive number" when input values are negative "Invalid Entry" when input values equal 0
Here is my code:
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click

I am doing a project on sending mass email. My codes should be able to read contacts/email from the SQL Server 2005 database and send mass email with attachments.Below are my codes for sending email. My windows application limitation is that it can only send email from a valid email address to a valid address one at a time with the help of a relay server. Also, it doesn't allow the user to attach attachments and could not read from the sql server database.[code]

View 39 RepliesI have a large ASP.NET project where I want to do a mass search and replace (about 3500 instances)
I want to change
If strErrorMessage.Length > 0
If strSomeString.Length > 0
If strWhatever.Length > 0
and any other similar call to the Length method from a string to the following
If Len(strErrorMessage) > 0
If Len(strSomeString) > 0
If Len(strWhatever) > 0
Anyway to reliably do this in one shot?
I can do a search and replace for something like If *.Length > 0 --> If Len(*) > 0
This just won't work though as it won't understand how to rearrange it properly. Currently have VS2010 and N++ at my disposal.
