Required Field On Form Tab Page

May 29, 2009

I'm using VB 2008 with .Net 3.5 and I want to check that a combo box has a selected value greater than 0 (default = Nothing Selected) before allowing the user to move off the tab page to another tab page. The Leave event does not allow me to cancel and the Validating event on the tab page does not fire unless the user has at least visited the combo box field.

Asp.net - Using Javascript On An Aspx Page That Uses A Master Page - Which Contains The Page In A Form?

Aug 7, 2009

I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

Add Another View To Display Same Page With One Less Field?

Nov 10, 2010

I am just making the switch from WebForms to MVC and would like to ask what are the best ways of hiding particular fields in the view. Assuming we have a model named WishList that has a list of gifts kids want for Christmas and the child's name. We want the elves to view the list of gifts, but only Santa Claus can view the child's name. Would it be best to have two views for the WishList (one for Santa and one for the elves) or is there another way to handle this? My concern is that the number of views can start piling as high as the snow does in the North Pole by the time I enforce all of the visibility settings required in my application.

Form With A Tab Control That Has 18 Pages - Click On A Tab It Opens The Page And Select A Textbox On That Page

Mar 8, 2009

I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.

Display Form When User Interaction Isn't Required

May 24, 2011

I've written a program using Visual Studio 2008 Standard Edition in Visual Basic. It's a Windows Forms Application. The program is very simple, it just reads a directory of text files, parses the text and outputs another text file as .CSV file
for import into Excel. There's no user interaction required but it never displays the form and therefore the progress bar. If I put a GO button on the form and modify the program so that the subroutine that does the processing isn't called until the user clicks GO it shows the form and the progress bar etc. How can I make the program run at startup, show the form, show the progress bar and then pause for 10 seconds or so and then exit?

The following is my function. The error occurs when I try and set the from email address. It gives me an error: "The specified string is not in the form required for an e-mail address." But the email address is in a perfectly legitimate format (I changed the email so I don't get killed with web-crawlers pulling addresses, but it is the exact same format). Hope someone can see what I am obviously missing.

Database Condition - All Inputs Required From User On Form

Nov 4, 2009

I am building a program where all the inputs (10) required from the user are asked on one form. Since it is not possible to let fields blank on the database, I would like to know how can I build an 'IF' saying that if all fields are full, then the database CAN save all the input. So that if there are any field blank, it won't save. I just dont know how to do the database condition. Thats all.
