I've mainly been recording keystrok macros... I created visual basic code that allows the user of a template to hide table gridlines - which works fine. The code to show gridlines does not work if the table has only one row. Here is the code - it is getting "stuck" on the
.LineWidth = wd
LineWidth050pt for a horizontal border, as there isn't one. I don't know how to change the code to not execute the command if a horizontal border line does not exist.
With Selection.tables(1)
With .Borders(wdBorderLeft)
.LineStyle = wdLineStyleSingle
.LineWidth = wdLineWidth050pt
.Color = 5592405

i have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data. Below is code I used to get the data when the Save button is clicked. [Code]
Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part. Plus even then I don't know if this would do what I want. EDIT: Ok I fixed the error and got it kind of working, but now I have a new question. Now, I put a button on the form that I can use to load the data when I choose to just to test. This works, it takes the data from each time slot and loads it back when I click the button. New question is how can I get it to load as soon as I open the existing appointment? Putting it in the form load event won't work because it checks for data before there is any in there.

I am trying to Send an Email with an attachment (using Gmail) but I keep getting errors like "Operation Timed out" or Failure Sending Email". It was working earlier today but I found out that i needed to add Using statement because the email was having a file open that had to be deleted after it was sent but afterwards it doesn't work.

And it is supposed to read multiple lines from LimFile and send it to a string in VB.NET.Problem is that when I debug it, I see the string is there in full length. And when I split it with vbNewLine, it shows that theres only 1 line, aka nothing is split, like the newlines have been lost.
Why does my the declaration of my string in the code result in the following error? Is there a workaround?
Code:
<script runat="server">
Protected Sub form1_Load(sender As Object, e As System.EventArgs)
Dim x As String = "</script>"
[code]....
Error: Statement cannot appear within a method body. End of method assumed.
Note: The following page did not fix my issue and instead resulted in the string </script> being output in my page. ( VB.NET hates </script> tag in string literal )
I have a form that requires input from a user that will update a database table. So they are offered input boxes. What the input box will do is ask the user to enter a date, what that will then do is to mark a field marked 'code' in my sql table as "holiday" for that entire day.

Basically, I want to have a database that's lightweight and I won't need to install amillion other things on my clients computers for them to access this.I just need a simple method of reading and writing values so that they're not hardcoded into the program. I could do MySQL (which is what I'm very familiar with), but it doesn't need to be making calls remotely.

The idea is that while you use the class to draw, it will write a logg of what you have done, which can be used to draw it back later. In that way i would be able to store a drawing with weary little disk usage.
