Hi,
I am writing a windows app, and in the function I need to check and see if a variable (email), is a valid email address. I know how to use the one in the aspx pages, but as I am new to windows apps, I am struggling.
my variable is called "strEmailAdd"
How can I pass this to a regular expression, and check if it is valid. If valid, return "Y", else return "N"?

Hi,
Here is an article which explains email validations using Regular expressions.
Email validations using Regular Expressions.
dim reg as Regex = new Regex(@"^[a-zA-Z'.]{1,40}$")
Response.Write(reg.IsMatch(txtName.Text))
if (!Regex.IsMatch(txtName.Text,
@"^[a-zA-Z'.]{1,40}$")) Then
end if
This is a simple example from msdn. Change the regex according to the article i suggested in the link provided.

i set a picturebox control on my form and i load an image to it from the image property , i also set the Visible property to "True" but when i debug the application , i can't see the image in the run mode, only the border of the picturebox. The extention of the image is "JPG" and "Gif" , and i can open those pictuers easly as i'm using windows XP, but i still can't see the picture on the run mode. is there a code i should use to load the image in the picturebox at run time , and if yes where to place this code, in the main code body of the form or behind the picturebox itself. please advise and thank you again
i could found a possible code which is
< Dim img As Image
img = picturebox1.image >
but when i use it i have an errore which state that Image is not a type.
please advise and thank you.

You have to create parameter for report that parameter will be assigned at run time.

Hi!
check the extension for your image, maybe it's not supported on your machine. You may need plugins to see some pictures. Cheers!

Hi,
i cant disable the right window logo keys when i run my application.
i use the following code to disable the window logo keys, but it just can disable left window logo key.
private sub Textbox1_KeyDown(Byval sender as object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Textbox1.KeyDown
if e.keycode=keys.LWin and e.keycode=Keys.RWin then
e.handled=true
end if
end sub
Pls Help me...

How about changing your If statement to 'OR':
If e.KeyCode=Keys.LWin Or e.KeyCode=Keys.RWin Then

still cannot disable the right window logo key.
If e.KeyCode=Keys.RWin Then
code here also just allow me to disable the left window logo key.

You might want to set a breakpoint on that If statement and see if its even being called when you hit that key. If it is, then you can peek at the e.KeyCode to see what value it holds. Then you can change the code to look for that value. Be warned! Not every keyboard has 2 Windows logo keys.

There is an application in VB6 and n no. of user are using that application (.exe). In this applicatin (.exe) every user are interacting with a recordset of SQL Server 2000. If any of user update or delete any of row, a message should be sent to every users telling them that a specific id's row is updated or deleted by <username> in a message box.
I think this can be done by using recordset's dynamic property i.e. "Row Update Notification Property" and "Row Delete Notification Property". But i do'nt know exact coding for it.
Please guide me.
Thanks and Regards

This won't tell you the backend database was modified, only that the row in that copy of the recordset was changed.
You're looking for SQL Server Notification Services[^].

Thanks for your reply. Actually, i want that if any user update a specific column or delete the row in recordset; a message should be sent to every user at the same time.
Can you please provide me the way by which i can install SQL Server Notification Services. The link you provided me tell about services; but how to install?

Items 2 and 3 in this[^] list will let you download NS2.0.
And if you click on this previous link I gave you, there is a section dedicated to Installing it.
