the application I'm building is ALMOST done. The ONLY final feature I NEED to add is the ability to receive email. Now I'm using VB 2010. How would I go about doing this? Would I use 2 listboxes and a form with labels on it to display the message. I haven't any code yet. How in the world do I do this??
View 2 RepliesI have a section of code in which I want to display a messagebox after a form is displayed... as the form loads. me.show messagebox.show If I don't use me.show first, the messagebox appears before the form is displayed. If I do use me.show first, the form appears, but is not always complete before the messagebox appears. Is there an easy way to poll the form to see if it is done displaying without using a timer?
View 14 Repliesi'm trying to display a random messagebox that displays a message associated with a character. the character image displays and the user clicks a button to guess the character if it is correct, one of three messages should randomly appear that is associated with that character (there are 4 characters, so there are 12 possible messages total. 3 for each character) but as it stands now, the picture box on the form displays the character name so the user doesn't have to guess which button to push. i need to remove the name from beneath the picture so only the buttons have the name and the user is forced to guess and i don't have the messages randomly popping up. only a messabebox that says correct i added a message box in the code but i can't figure out how to randomly get the messages associated with the characters to appear?

View 2 RepliesAm writing a VB.Net app written in VS2010. This displays some reports in several forms. (Am using Crystal Reports though this is incidental to the problem). The user needs to be able to check these, then confirm if he wishes to run the update process or abort. My first idea was to ask the user to reply using a messagebox. But of course this is modal, so the user cannot browse through the reports.
I thought of other options but each seems to have problems:
- export the reports as PDFs, then display report in external Adobe Reader Window using System.Diagnostics.Process.Start("AcroRd32.exe", filename).
- create a non-modal message box or equivalent. This loses any concept of program flow, so am unconvinced by this.

View 5 RepliesAre inputboxes nolonger dynamic in size?in VB6 I could list say 12 months of the year along with month numbers and ask the user to select a month number. So the code would go:strmsg = "1" & chr(9) & "January & chr(13) & "2" & chr(9) & "February" & chr(13) e.t.c. {for each month} & "Leave Blank To Cancel". This would list Month 1 to 12 plus the last line.
There appear to be 2 problems using vb.net:
1The input box does not grow virtically to accommodate a dynamic number of lines
2The chr(9) function to produce a "tab" does not appear to work, whilst the chr(13) (Return) does work

View 3 RepliesI've created a form with several controls to specify the inputs to my program. They include TextBox, OpenFileDialog, Button and even a user control for numeric input. When the user clicks the 'GO' button, the program begins it work. Opening several files and processing a bunch of numerical data. This could take many minutes/hours with large datasets.
What I've been trying to do is have another window/form open up and send status information to it for the user to view. The info to be displayed is varied and constantly updated as the program crunches the numbers. Many many programs do just this type of activity.
I attempted to create a second form with a huge TextBox thinking I'd just write stuff to it. I called the .show method within the .click of the 'GO' button and of course the form is displayed but control of the program's execution doesn't return until the form is closed. How to I maintain execution and have a second window/form to display status?

I teach VB in college, using the Express edition. I was doing an exercise with my class today using the MessageBox.Show() method in a Windows Forms application. But when I tried entering it in the edit window, it gave me the following error message: 'show' is not a member of 'MessageBox' and it did not show up in the Intellisense box. Most of my students' computers did work with that method, but one or two of them didn't. Meanwhile, I had to revert to the MsgBox() function to get through the exercise.

I've run into a couple of errors within my program which reads a text file. When a user clicks a button to read the textfile and an exception is thrown, i have it displayed as a string in a message box, but an additional message box related to runtime error 52 'bad filename or number' has shown up and continues to pop up, even after clicking ok. I am currently working on the error itself in the textfile, but until I can work around all of the variables with reading this file, I was wondering if there is anything I can do to either prevent the runtime error box from popping up or figure out why it's popping up so many times. The really weird thing is sometimes after clicking ok on the initial message box displaying the error string, it won't pop up and other times it does, repeatedly.

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?
