View 2 RepliesI am working on a project that has the user building scrapbook pages through several different forms. When the user selects something a presses a button I have the information about the selection load to a list box which is on a CheckoutForm. One of the options I have is for the user to save what they have made (this includes the information in the list boxes) and return to a previous form to build another page. I have been trying to use the Me.Close() but it does not save the information and using Me.Hide() displays the wrong elements on the forms.

then the LicenseNewForm appears. The problem the I stumble upon is how I get the information from the license form to the main form when they click a button in the license form or close the license form. The information is more then just a simple input, so I can't use a InputBox call because the license form has 3 comboboxes and a textbox to get the input from the user and then I need to send that input to the main form.

View 9 RepliesSo my question is that I have 2 list boxes in two forms aside from the main one. and I am trying to transfer what I choose in the side form to transfer to the list box.
several questions: Why does the blank list form I have in the main form create a problem when I enter a name for the list box and why does it appear in the box when I put it there? As you can see in my errors. It doesn't seem to recognize the listbox that I wanted to leave empty in the main form.
Second question is how do I get names to add in the main form list box. I believe I have the right code but I seem to be missing something else as well. I want the names to display in the main list box and the integers to add up together so I can separately figure the tax and shipping myself.
Here are some pictures and codes

I tried my best to shrink down the program to the following code. In this example, I have UK and USA as valid countries. If someone lives outside those countries, I wanna show an error message and highlight them on the gridview. For example, John and Chris are from China so they should be highlighted on the gridview. Either just Name or the whole row can be highlighted.

View 4 RepliesOn my form, I have 2 textboxes, where I use the validating event to validate the input. But when the user closes the form and the focus is on one of the textboxes, the messagebox appears (as in the validating event), and after that, the form is closed. Setting e.Cancel to false in the formclosing event don't work too. As I see, it is a common issue. One thing: CausesValidation don't work too. There are (and will not be) a cancel button, and I can't write a sub to set the causesvalidation of the textboxes to false,

View 7 RepliesGot a proccess thread thats in charge of loading a listbox full of the first line of text for richtextbox items on form load. Though I use Me.Invoke(New MethodInvoker...) to add items on the main thread so its thread safe it coughs when the first line of rtf data are thrown at it, acting as if I hadnt called adding the items on the main thread.
Up at the class level:
Dim Worker As System.Threading.Thread
In the load procedure for the form:
Worker = New System.Threading.Thread(AddressOf WorkerDo)
Worker.Start()

I"ve also tried to remedy this using a delegate to invoke the listbox before attempting to update it, but the invoke method itself is throwing the exception. I am not using the default instance of the form (a new instance of this form is created). Anyone know how I can get around this? I can't load the listbox full of items directly in the form's load procedure because work takes place in the thread beforehand so there are strings to add to the listbox. I've got MS Visual Studio 2008 Pro and Vista SP2 (latest updates applied).
