I'm using MessageBox to give some information to the user, but when such a box pops up, I want it to block access to the main window. So, until the user has clicked "OK", they should not be able to click (or even focus on) the window that's below it.
Does anybody know how to do this? I've noticed that MessageBox has very few functions, so maybe I'll even have to use a different object for this.
The application uses ADO.NET to invoke sprocs for nearly every database operation. Some of these sprocs also contain a fair amount of domain logic. The data access logic for each domain entity resides in the domain class itself. ie, there is no decoupling between domain logic and data access logic. I'm looking to accomplish the following:

From my login form, and when a correct Username and Password has been succesfull and I get a messageBox saying "welcome to your System" (Picture Below) and when I press the OK button in that MessageBox, I want to open Form3.do I add code to the Underlined code (below Picture), or Do I write a completley different code after the messageBox code.
[Code]...
I'm not really sure exactly how the question should be phrased, so please be patient if I ask the wrong thing.I'm writing an ASP.NET application using VB as the code behind language. I have a data access class that connects to the DB to run the query (parameterized, of course), and another class to perform the validation tasks - I access this class from my aspx page.What I would like is to be able to store the data server side and wait for the user to choose from a few options based on the validity of the data. But unless my understanding is completely off, having persistent data objects on the server will give problems when multiple users connect?
My ultimate goal is that once the data has been validated the end user can't modify it. Currently I'm validating the data, but I still have to retrieve it from the web form AFTER the user says OK, which obviously leaves open the possibility of injecting bad data either accidentally (unlikely) or on purpose (also unlikely for the use, but I'd prefer not to take the chance).So am I completely off in my understanding? If so, can someone point me to a resource that provides some instructions on keeping persistent data on the server, or provide instruction?
Concrete Example: We recently hired Inspector Gadget to insert data for the Sign Inspectors who go 'round inspecting the highway signs to make sure none of them have been mangled or stolen by bubble-gum chewing, normally upstanding members of the youth city council.If Gadget can prove his mettle then he might get promoted to do the actual sign inspections. For now, his only job consists of going to this intranet site an inputing information about the most recent inspections. The district, county, route #, section of road, and dates the sign was installed and inspected.
Of course any of us who were alive in the late 80's are familiar with Gadgets ineptitude. So the site is about as Gadget proof as we can make it. The district/county/route is all filled out through a dropdown list, he only has to manually enter the section start and end and the dates. On occasion he fumbles the mouse and ends out swapping the begin and end of the section, doh! So the text turns red to alert him of the mistake. Unfortunately he chose to wear his anti-red sunglasses today that turn all red colors to black. Well, after attempting to submit the data it shows him an error message telling him where and what he needs to fix. Unfortunately he fat fingered the keyboard and instead of inputting 1.337 he put in 13.37 (miles)- and the road is only 10 miles long! Well, now a message (a modal div) pops up and tells him that the real mileage for the road is 0-10, and that his entry will combine three sections of the road. Then he is given three buttons to choose from. Cancel, which allows him to go and modify his data, Constrain, which will convert 13.37 to 10, and Override which will allow him to input that data anyway.
"Yowza!" Gadget exclaimed, and clicked cancel to go back and fix his mistake. Well the next set of data he input correctly, so a confirmation message popped up showing him the changes he was about to make and asking if it was OK to continue. Well, unfortunately Inspector Gadget knocked over his coffee cup, scattering detritus across his desk. In his haste to clean it up, he clicked "OK", but not before his Go-Go-Gadget electro-magnet accidentally flipped a few bits on his computer, changing the county in the form from ARKANSAS to AKRSANAS, doh!
Had the data been stored on the server across campus, and the only information passed was "OK" or "Cancel", this would have been avoided.Of course I can always validate again after the "OK", but it just seems like a hacky workaround.
I have a Boolean, user scoped setting. I access it through a referenced class library, called Settings. This class library has a Module with properties:
[Code]...
While the code is running this works. But after a restart of the application the new value is not persisted.
I have a table, Users, with a related child table, UserSecurityGroups. In my GUI, the operator would select a user from a list. The program would retrieve the user record and allow the operator to edit the user data in one form. The operator could also edit the UserSecurityGroups of this user on another form.
I am considering using a singleton class for user instance retrieval and persistance back to the database. If this is a good practice, I want to use this with many other tables in my DB. My question is: Is this a good practice? What pitfalls am I missing? What would you recommend as an alternative? Would your recommendation change since I also have tables with three or four levels of relations (as opposed to two in the example above)?
Here is my proposed code:

I am amateur programmer.so far, I can use Visual Basic .Net only. That is all I know!!How can I refer to a MessageBox?or how can I Programatically handle a MessageBox after it is displayed?I need to close a MessageBox after certain time if no response from the user.
View 3 RepliesI have this
Dim st1 As String = sref.ConfirmLogin() 'A WCF method call.
Windows.Forms.MessageBox.Show(st1 & Environment.NewLine & "blue", "Result")
What is interesting about this is that there is no new line in the messagebox, and "blue" doesn't show up. If I reverse the order, then all is well. If I turn st1 into some other random string, all is well. However, as long as st1 is a string that comes from the WCF call, everything after st1 in the MessageBox is ignored.So what is coming from the WCF call?
The lines are these:
resp.GetResponseStream.Read(buff, 0, 99)
Return Encoding.ASCII.GetString(buff)
resp is a WebResponse object, though that shouldn't matter, as the key is that I take a stream, move it to a buffer, then turn that buffer into a string. What is it about the string that is alterning the way the string is displayed.If I highlight the "st1 & "Blue"" part, and press Shift+F9, it is all there. What I do notice is that there is a significant space beyond the end of st1 and before the Blue. Trim doesn't get rid of this space. My theory is that what is there is a series of Null bytes, and MessageBox is interpreting that as the end of the string and terminating the display at that point, even though it shouldn't really be terminated there. That's especially interesting because I can add in an Environment.NewLine, which would normally add a new line, but even that gets ignored.
I have a Main and a Secondary form. I want that the secondary form appear if the no button in the messagebox is pressed (but the main main don't). Only if I press the yes button or when closing the secondary form the Main must appear. How can I do that?

View 7 RepliesI want to add a yes/no function to a message box (Are you sure you want to exit?) in InfoPath 2007. If the user clicks 'Yes' the InfoPath form closes, if no, then the user is taken back to the form. From what I have read this will not happen in InfoPath. So, I added a new windows form that has the Yes/No buttons.
For the 'No' button, I have (me.close) which closes the windows form and the user is left with the InfoPath form. when the user clicks 'Yes' meaning they want to close the windows form AND the InfoPath form. Below is my code so far.

I have a strange problem here. In my code, variable b string, has the value "Test Test Test". This value we can see while debugging the variable as well as in the text visualizer.Now the problem is, if I show the same string using Messagebox, the value is just "Test". What can I do here to get the complete value.

View 3 RepliesIm writing a program that is supposed to display a name, which is one array, and then show the phone number to that persons name, which is another array. What happens is when you enter the name, without any capital letters, it will show the number, then show the exception messagebox that says you have no friends with that name. When you enter a capital for the first letter, it will show the number, then it will show the messagebox with the name and phone number. My issue is 2 things,
1.) I need to have the exception messagebox come up only when a name is not entered, and
2.) I need to have a partial code snippet that will display the correct information even when a full name is not entered. [code]

I have an application that has a timer within the main form. Every 5 minutes it checks the database for notifications and if any are due it displays the details in a messagebox. If the main form is the active form, it works fine (message displayed). Even if I create another form and display that modally, the message is still displayed. If I minimize this second form, the message is displayed.
However, if I am writing an email when the timer is called, the message box isn't displayed on top.Is there any way to make sure the MessageBox.ShowDialog method always displays the dialog as topmost?I have tried using a new form instead of MessageBox.Show, setting the TopMost property to true, but that didn't work, either.
I just need to know how to have plain text and a variable in a messagebox.
For example: I can do this: MsgBox(variable)
And I can do this: MsgBox("Variable = ")
But I can't do this: MsgBox("Variable = " + variable)
