Displaying Form After Removing AxUpDown
Jul 2, 2010
I'm migrating from VB6 to 2008. I am replacing a text box and a AxUpDown control with a Numeric UpDown. I have added the Numeric Updown before deleting the AxUpDown - to check its working. There are no references in the code to the AxUpDown but when I delete the control and run the application I get the form displayed but all the fields are blank, the form is partly see through and the application hangs. I'm not sure what is going on and don't know where to look.

I'm dynamically creating x number of textboxes on my form. Once I have done this and the user has done some stuff with them they need to be able to remove all of these textboxes to start again. I've written this code to go in a button, but it only gets rid of two of the textboxes at a time rather than them all in one button click (so it takes like 8 button presses to clear all of the textboxes on the form). Can anyone see the problem?
Code:
For Each ControlObj As Windows.Forms.Control In Me.Controls
If TypeOf ControlObj Is Windows.Forms.TextBox = True Then

This is my first post here as I am in the process of writing my first vb program. I just recently learned VBA and prior to that I had no programming experience. I decided that my first attempt with VB would be to convert a program that I previously wrote in VBA. It runs in an excel workbook but it doesn't actually use any excel functions so I figured it would be acceptable to convert. I am having an issue with removing controls on a userform. A commandbutton adds a line of about 6 controls. The user can add as many lines as they need to input their data. One of the 6 controls is a delete button that deletes the line of controls next to it. I have created a collection named Cashflows that holds each line of controls and each line of controls is named with a number that indexes the name to the line that it appears on in the form. In VBA I use that number to delete the actual controls from the userform and reposition and rename the remaining lines of controls.
Private Sub Delete_Click()
Commandbutton3sub(CInt(Right(Delete.Name, Len(Delete.Name) - 6)))
End Sub

I have a lot of buttons on a form (144) that need to be removed. All their names begin with "R". So I used this piece of code.
Sub RemoveBookingButtons()
Dim cntrl As Control
[CODE]........................
However whenever I run this sub function, it deletes every other button starting with "R". better code or point out if the flaw is in that piece of code or it is hidden somewhere else in my program?

But after seven second altough the splash screen closes but it also closes the MDI form too. I am not able to figure out the problem.

I'm trying to remove a line from a text file that begins with a set value.
The idea would be to paste values into a Windows form, which then finds each line that begins with that value (a 5 digit number) and removes those lines from the file, and then removes the gaps.

I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).

I have a windows form with listboxes, buttons and a checkbox. It works fine at home but when I take it to school it doesn't display properly. I have been given full privileges and the .NET framework V3.5 is installed. I have all my buttons/checkboxes on the right hand side but they don't display like they aren't even there (there is no extra blank form space either). The form sized wasn't locked

I've been working on a project now for some time and as a result, when I have something new to try out, I do a little "proof of concept" project and then port it over to my real project (mainly to make it easier to follow when trying to work out new issues).Up to now, I've been relatively successful at it.But here's what I'm running into with this particular project.First, a little background.When the operator enters data into certain input fields (textboxes), either a listview or a datagridview appears displaying multiple columns of information.Once the line is selected with the proper info (equip. id or type of job or whatever), that info gets displayed in the textbox.The problem occurs when display is clipped by the window size.Let's assume for simplicity sake that I can't enlarge the display window.
So I rethought that and decided to create another form that has no borders and the only item displayed is a bound dgv.So I created a proof of concept project that consisted of two forms: form 1 that contains a text box and form 2 that contains a dgv control.when run, form 1 is displayed.When I type a character in the textbox, it calls form 2 and searches the dgv for the first char I entered.Since form 2 is the current form, as I enter additional chars, I build the string, search and if the chars are valid input chars, echo them to the textbox.Once the data line on the gridview is found, the tab key is used to do the select, close form2 (the dgv) and populate the textbox of form 1.This all worked.That is until I tried to port it over into my real project.This is where I'm obviously missing some key aspect of VB.Net and how all the forms and threads and handles work.To get right to the issue and skip alot of what happens in my real project, I was able to duplicate the problem by just creating one more form in my proof of concept project that just has a button on it.That button when pressed, brings up form 1.When I start to type in the textbox, after I enter the first character, form 2 displays, which is as expected. But when I enter the second search character, a second instance of form 2 opens and it searchs for the second character I typed.If I enter another character, it gets added to the second char and located in the dgv of the second instance of form2.When I press the tab key, textbox of form 1 does not get updated but the second form2 does close.The first form2 remains.

I seem to be having a problem with displaying data in a second form. I've created a linear search algorithm which works just fine - it locates the records from the database. I now want to be able to display the record in another form, I've attempted this using the code below but it doesn't seem to work:
Public Class formSearch
Dim searchItem As String
Dim currentRecord As Integer
Dim Provider As String
Dim Source As String
[Code] .....
The commented out lines are the ones that don't seem to work. The "txtfirstname" and "txtlastname" fields are located in the coding of another form, called "formcustomers".

I am writing a program to control light and sound for a show I'm working on.
The program has buttons and stuff controlling music and sound effects but I am at a loss as to how to get the video part to work.
My computer is hooked up to a projector in extended desktop mode. (I can't change that, otherwise my control panel would show up on the big screen.
I need the video to display on Screen 2 (the projector), so I made a form and used this code:
Dim screen As Screen
screen = screen.AllScreens(1) 'the array is 0 based
Form2.StartPosition = FormStartPosition.Manual
Form2.Location = screen.Bounds.Location + New Point(0, 0)
Form2.ShowDialog()
to display it when I press a button. This worked fine, I set form2's border to none and fullscreened it, tested again, no probs. My problem arose when I tried to add a WMP ActiveX control. I ran the program, pressed the button, and... form2 (along with WMP) appeared on my laptop display. I desperately need this by tomorrow. If no solution is available, is there an alternative to WMP?

i'm working with a sql (2005) database and using visual studio 2010. I've created a system where one of the forms is a find/search form. A user can enter in for example, a customerID and once they click on "find/search" the customerID will be searched in the database and if found, all relevant information about the customer will be retrieved and displayed in another form (find/search results page). I realise that this can be done using an SQL statement like follows
searchStr = "SELECT * FROM Customer WHERE CustomerID LIKE CIDTextBox.Text%"
What i'm unsure about is how to execute this SQL statement once the "find/search" button has been clicked and how to display the founded results in another form.

I have a VB 2008 windows application that I'm working on; the data are stored in SQL. I have a lot of fields that user will need to fill out. Some fields that not displayed on the form are actual combination of few filled out fields. For example - user types in first name, middle name and last name in 3 separate boxes on the form and I'd like to combine those and assign it to the "FullName" field. I know it's duplicating the data but this FullName field would need to be merged into report as is in a different program.
Another example - user will pick a data in combo box that is binded to a different table, but I need it to auto-populate 3 fields in the main form (those fields are not displayed). I know that I can actually add all those hidden fields on the form and assign calculated values based on user input and then everything is saved with built-in "Update" command. I was wondering if there is a way to specify those few calculated values as parameters and still use "Update" command without actually typing long Update command. I have over 400 fields - very lengthy command.

I'm using Microsoft Visual Studio 2008 to create an application (.VB). The application connects to a Microsoft Access 2007 database. When the user starts the application, the application pulls in the data from the database via the "TableAdapter.Fill" method. The user can then add/update/delete records in the form and those changes are saved and confirmed in the database. The problem is when the user close completely out of the application and restarts it, the modifications that were made and originally sent/saved to the database are wiped/deleted. It appears that the dataset in the application never saves the modifications and when the program restarts it uses the data that was originally loaded into it during the design/build phase of the application.
