I have been able to connect to the string and the database from where I need to check the username, but in my page it is not checking whether the username is correct or not.

I am doing a simple backup of sql server database through VB.NET form. It gets executed well but I want to display details of successful query execution in a label (i.e. time taken, database size etc.)
The message which I want to display in label is like "Processed 296 pages for database 'aaa', file 'aaa' on file 1. Processed 1 pages for database 'aaa', file 'aaa_log' on file 1. BACKUP DATABASE successfully processed 297 pages in 0.522 seconds (4.660 MB/sec)."
This result we get in sql server query window when we execute backup query there. I want to get this message in label when I fire backup query from Windows form in VB.NET
I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?
As the title says,I want to just have only numberic/decimal values accounted for, if it is negative or if anything else is entered into the textbox, how do I have a message display for that?

View 4 RepliesI have a aspx page with several input fields(couple of int's and strings) and 3rd party gridview. Data is validated, and stored procedure is called from code behind to save data in DB.

I've added a database to my application with 2 fields:"ip" address and "started" that holds the number the application was started from that specific IP.I want to upload the database to my site hosted at google.sites. When the program is started it should make a connection with the following cases:
1-no connection with the database (possible no internet available) - it should display an error message
2-there is connection, the IP is not stored on the database, it addes the IP to the database and the field "started" with the value 1
3-there is connection, the IP is stored on the database, it increments the field "started" by 1
I am working on a program where a user either enters "small" or "large" and then the number of toppings. Once the user has done that my program outputs the total cost of a pizza based on user input. If they enter something else besides a number in the txtNumberOfToppings I am trying to show they message box that says "Re-Enter a valid number!" Likewise I am trying to display the error message "Re-enter a number that is 0 or greater!" If they enter a negative number into the textbox. However they do not display when I do enter invalid input.

My intent is to have the code - on a button.click event - check the Username and Password fields and return an error depending on which is wrong. Or if both are wrong, return a different error message. I've set the username as parts and the password as parts (still learning how to use external authentication). [Code]

Is it possible (I'm sure it is) to validate a user's credentials against Active Directory without using Directory Services?I'm building a Browser-Based WPF application which requires users to login to and get validated via Active Directory. Since .Net 4.0 (or maybe 3.5) accessing Directory Services from an Application requires the application to be fully trusted. Since IE won't provide full trust to an application if it doesn't have the signing certificate in it's cert store, the application is refused startup permission.
If I don't use Directory Services, then I can leave the application as Partial Trust and validate my user's credentials without having to install a certificate on each user's machine.

I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
tmrnote.Start()
Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.

View 4 RepliesI'm creating a rewards system for school where pupil earn points for good behavior which they can then use to purchase things like a packet of pens.

View 2 Repliesi currently have a form and 2 picture boxes on it. One of them (pic_Background) is showing a landscape and it is meant to be the background. the second picturebox (pic_Man) is a self-edited PNG image that contains a 'human'. The human itself is the only non-transparent part in the picture. everything around this human is made transparent using photoshop. i verified that by opening that png file in mspaint and irfanview and checked if the surrounding of the human is transparent and, indeed, it is. so i included this pic into my pic_Man but all i get is this:[URL] it is the default gray backcolor of the picturebox around my human. i tried almost everything but i couldnt get it. how do i make it completely transparent, so that the backgorund is visible around my human and not that gray color. of course i switched the backcolor property to transparent but it didnt help.i also tried to use the MakeTransparent-Method but without success.
