I have a CheckingAccountForm and a CheckingAccount class. I have 2 variables AmountEntered and TotalAmount. The user enters an Amount and hits the calculate button. So now I send the AmountEntered to the CheckingAccount class where it is added to the TotalAmount and I have to send the TotalAmount back to the CheckingAccountForm so it can be displayed in a textbox. Can someone give me an example on how to do that? I get the AmountEntered to the CheckingAccount Class and managed to calculate, but not sure how to get the TotalAmount back so I can display it in the GUI's TextBox for the TotalAmount.

View 2 RepliesThis should be fairly basic but maybe the search terms are too general to find relevant answers.I have an MDI form with a conventional toolbar. When I open a small non child form I want to set focus back to this main form so the user can click the help button on the toolbar if necessary.
Tried frmMain.Select() and frmMain.ToolStripButton0.Select() at end of small form load but it doesn't work. The user has to click the help button twice, once to select it and once to open it. A minor problem but annoying.
I have created an application that I am using the VB webrowser control. The users needs to login to a site to display a particular webpage. The sites login is in a popup and what appears to be happening is the popup is launching outside my application (has IE in the title). If I enter uers/pass and try to login the information is not being passed back to my webrowser form.
View 5 RepliesI have a form being called form several forms using ShowDialog().
1. Is there a way for called form to know which form called it by receiving a code or key from the calling form?
2. The calling form has a gridview. How can the called form pick up a column's value from the currently highlighted row in gridview in the calling form?
I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]
View 1 RepliesRequested were made by Businese Analyst to set the few Main FORMs VISIBLE PROPERTY TO FALSE when the POPUP FORM is loaded.
[Code].....
When the MAIN FORM loads the POPUP FORM, on the FRMPOPUPCUSTOMER-FORMLOAD even, it has to set the MAIN FORM Visible to False.
When FRMPOPUPCUSTOMER FORM IS UNLOAD it has to set the MAIN FORM Visible = TRUE.
How to the coding is to ensure that different MAIN FORM when loaded FRMPOPUPCUSTOMER it will turn the MAIN FORM Visible to FALSE.
I have two forms. Form1 and Form2. The user is supposed to fill out some information in form2 which then will be used to compute some data in form1. However when I used the code, Form2.Show, within a function in form1, the form2 is diplayed but when the user fills the data and submits them using the ok button, the code does not return back to the function in Form1.

I'm upgrading a project from VB6 to VB2008.I have a routine that clears a combo box, named 'cmbDataTable' which could be on any form. I pass the form and the combo box is cleared.

I assumed it would be the same in VB2008 but I get the error.'cmbDataTable' is not a menber of 'System.Windows.Forms.Form'I am working my way through the project, first updating the global procedures - this is one - I haven't written the calls so cmbDataTable doesn't yet exist.
I am trying to pass information to parent form from modal form in vb.net winforms application.
1.) I created a copy of a form and displayed it using following code.
dim f=new frmParent()
f.show()
2.) Depending on conditions a button on frmParent opens a modal child form and asks for some informations. I used following code for that:
dim f = new ChildForm()
f.showDialog()
Both code works fine. When user press saves in child form i need to close childForm and use the user types values in parent form. I know how to close the childform but not sure how to pass info from childform to parent form.

I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

I am having multiple forms with Find button provided. The forms i am having are Contacts.vb and Users.vb, i want to use single Find.vb form for both of these forms. I mean whether a user presses Find button from Contacts.vb or Users.vb the same form should be opened with corresponding data that is fetched from database. I tried using Find.Owner = Me from Users.vb but i don't know how can i determine from Find.vb that who is the owner. I tried to use that if owner of find form is Users.vb then fetch data from users table and if owner is Contacts.vb then fetch data from Contacts table. Unfortunately i am not able to perform this task.

View 2 RepliesI have three buttons on my main form, say Form1. Clicking any of the buttons brings up Form2 modally for input, it's a number pad. Now, depending on which button was clicked to get there, after the user enters his numbers, I need to change a specific label on Form1. In other words, btn1 clicked puts user input into lbl1 and so on... I could probably do this with a variable but wondering if there is a more elegant way.
View 3 RepliesI was having a problem with the debugger not stopping at breakpoints. After a lot of work that yielded no results, I realized that the problem was occuring in the form's load event and subs called from that event.
The problem is that it appears that the load event is not being called. Other startup forms in other projects in the solution seem to be working ok.
what could be keeping the the Load event from working?
I am building a program where for part of it the user can enter a parameter which will then query a database and populate a DataTable with the results if the number of results is greater than 1 it will call a "lookup" form to popuate a DataGridView with the DataTable, from this the user can select a row and the result is passed back to the main form or if the result is not there the "lookup" can be closed.
This works fine the first time the parameter is used to query and opens the "lookup" form and populates the DGV, but if the user returns the the main program after using the lookup form and enters a new parameter and the lookup form opens again the DataGridView is not created and populated. But i am 99% sure the DateTable is being populated as if the row count is 1 it will automatically return the single value and this is happening even after the lookup form has been used.
So it is just when the Lookup form is being used a second time the DataGridView is not being popuated or the DataTable is not being passed.
