Himanshu:
I have the same need to print a form. In Microsoft Access 2000 and higher, you can print a form exactly as it shows on the screen. I need to do the same in Visual Basic.net. Did you find out how?

AFAIK you've to go through the registry.
Under CLASSES_ROOT you'll find the key (=extension) with a default value. That's the name you're looking for

Dear Sir/Madam,
I have searched for some examples regarding "Scrolling". But I found scrolling of IDE, Scrolling of FlexGrid etc using scroll button of a mouse. But I want to scroll a Data Report/Active Report/VB Screen etc.as we scroll a HTML Page using scroll mouse. I found one snippet which will scroll a screen but not the data, i.e the screen itself is moving physically
(i.e Setting of "Top" property of the form). I don't want that way.
Please help me to solve this problem..
If there is a solution, please mail me at vishwanathbk@gmail.com
Thanks in advance

Can someone out there give a fellow a helping hand. I am desparately trying to code for a telephone validator. My form1 has only two objects, a textbox and a button.
Validate a phonenumber 999-999-9999
Where I am running into a snag is how and where do I create the substrings for the areacode, prefix, and phonenumber plus incorporating the "-" in char positions (3,1) and (7,1) Can someone give me some assistance or better yet help me code the whole tamole. LOL.

what do you mean by validate? making sure that it is a number that will reach someone? or just making sure it is 3 digits followed by a dash followed by 3 more digits etc...? or perhaps something else?

What I need to do is verify the first three 999 the first "-" second 999 second "-" and last four 9999. In the frmMain I have a textbox and a button. when the user enters a phone number 999-999-9999 the program will display one of the following messages:
"You must enter a numeric telephone number starting with the area code."
"You must enter a "-" after the area code."
"YOu must enter a "-" after the prefix."
"Invalid area code, please try again."
"Invalid prefix, please try again."
"Phone number is valid."
My problem is I have set the char to 12 in the properties for textbox1 and I need to create substrings for area code, prefix, phonenumber, and incorporate the two dashes "-" Can you help me!

The best way to validate a phone number is to use a regex. You don't need to mangle the string at all, but if you wanted to, string.split would be the easiest way here.

Believe me I wish I could but the prof wants us to use VB.NET and write the program and that is why I am stuck, I cannot figure it out. Can you assist me?

Regular expressions are built into VB.NET. Are you not allowed to use those ? The other way to do it would be to use the Split method on the string that has the phone number, and use the double.TryParse method to see if they are all numbers. You can specify to not allow decimal points. The only other step is to verify the length of hte strings, and how many groups there are. A regex will do this all for you in one go. Something like \d{3}-\d{3}-\d{4} should do it, and you can change it so the - can be a space, or whatever.

I tried that and it did not like it. LOL I guess VB.NET is a little more sensitive LOL.
Did you look at my code?
How can I manipulate the IsNumeric function to incorporate the dashes using the IndexOf method. See my problem is I have the keys to it but not the combination. I am just a greenie. Sorry.

That's a real hack, I would not use it. The answer though would be to use split to split into a number of substrings, by the -, and then stepping through each string.
12String wrote: I tried that and it did not like it.
A regex ? Then you need to work with it until it does work. That was off the top of my head.
However, I just tested it, and it works fine, assuming the number is xxx-xxx-xxxx where x is a number. Did I get that wrong ? What was your code ?

Yeah, VB sucks, but it can sure do this as easily as any other language ( and easier than vanilla C++ )
12String wrote: If (Not IsNumeric(Me.TextBox1.Text)) Then 'checks user input for numeric and range
This plainly does not work. You should try to follow my advice, and either use a regex, or, if you must, split the string and validate it from there.
12String wrote: If TextBox1 = ("999" & "-" & "999" & "-" & "9999") Then
MsgBox("You have entered a correct phone number.")
ElseIf TextBox1 = "999999" & "-" & 9999 Then
MsgBox("You need to enter a " - " between the area code and prefix number.")
ElseIf TextBox1 = "999" & "-" & "9999999" Then
MsgBox("You need to enter a " - " between the prefix and phonenumber.")
End If
This requires the numbers to be all nines. Your check input function should check all cases, you shouldn't be adding validation afterwards. The regex can be used to do this as well, although the split solution would make it easier to do this and give a detailed error.

How do you recommend I code that? The first line then I gather is correct, yes? If TextBox1 = ("999" & "-" & "999" & "-" & "9999") Then
12String

No, that is useless. It will only accept one string. Why bother concatenating 5 values to check if the user typed 999-999-9999 ? How often would that be the number the type ?
I'm not sure in VB, but in C# it's
string [] strings = theString.Split("-");
I suspect it would be
string () strings = theString.Split("-")
but I could be wrong. Then you can check if the array has three elements, and what their lengths are. A regex will tell you if they followed the format, but not how they failed to follow it. It depends on how much detail you want in your error message.
