I'm creating aWindows Application Form with several textboxes.
How can I save all the textboxes to a file, so that I can re-use the informtion.
In the VB book they only talk about one textbox.

|
|
|
|
Just simple write all the textboxes to a file (remember using a delimiter. So that u can parse back the string read from the file)

It works fine on small databanks, by on large ones, I get an error. And this is the funny part about this. Windows displays the Error Report Dialog, says Faulting Application (Event ID 1000)., by the program will still keep running, and if I do not press anything on the Error dailog. My program will run to it all finish. If it is faulting, why does it keep on running? The following information is from my EventLog:
Faulting application egdatabanktool.exe, version 1.0.2126.24660, faulting module unknown, version 0.0.0.0, fault address 0x1f48cbc1.

One thing more, is that the fault address (0x1f48cbc1) will always be the same, and if the run this program on the different computer it will be different address but show the same one each time the error happens on it. By the way my computer is: XP Pro (SP1), Dell 2.79 GHz, Ram 1 GB, DotNet 1.1 (Not SP1), ADO 2.7
If you have any ideas, please let me know.

I want to be able to detect if a PC is connected to a network.
I found the following which I thought should work.
System.Windows.Forms.SystemInformation.Network
However it always returns true even with the Lan cable removed from my laptop. There is no WiFi. I even tried a re-boot with Lan cable removed.
As a test I tried
System.Windows.Forms.SystemInformation.Username
and this did work correctly so I ssume the class is working.
Anyone know why or is there an alternative solution.
thanks
mike

Try using the Active DS Type Library, it has a few useful applications.

Thanks for replying and sorry for the delay.
Unfortunatley the network in question does not use Active directory.

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

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.
