I 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.

View 7 RepliesI fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.

I open a form using .showdialog and load some info onto it. I have code that runs on the MyBase.Load event. Basically, I have a Try, Catch, End Try block and if the Catch executes in preparing my information, I want the form to stop loading i.e. give a message and not show at all.

Why is my MDIChild form not being displayed in my MDIParent form? I want to click a button on form frmStudyResultsFilter which will then display an MDIContainer form frmCalculatedResults (maximized). When frmCalculatedResults is shown I want a small dialog modal form to be in the center of frmCalculatedResults. For some reason frmCalculatedResults will not show on top. Plus I get this error"Form that is not a top-level form cannot be displayed as a modal dialog box. Remove the form from any parent form before calling ShowDialog." Here is my code:
Public Class frmStudyResultsFilter
Private Sub btnCalculated_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculated.Click
Dim frm As New frmCalculatedResults

I'm sure I'm doing my login process for my app in a not so perfect way, but as with lots of things, it works. The issue is to make it work I have to use the very unpopular DoEvents thing. I would like my application to show a login screen before loading my main form. Currently I have a login dialog box with a FormOpen boolean property and an authenticated boolean property. If a user logs in successfully, I hide the login form, set formopen to false, and authenticated to true. If they cancel out, then I do the same and just set the authenticated property to false. If authenticated=false then I end the app, else I show the main form via application.run(MainForm)

I am making a Sport Carnival timer for a local school. Currently, I have the results go into another form that I want to get printed. I tried using the PrintForm method, but it did not work as I have to show, and have that window open to print it. This form also has graphics that I want to print too.
View 3 RepliesI'm trying to figure out how to set the form's location/size before calling the .show method. I figured out the location part, but still can't figure out the size part. No matter what size I set the form to in the designer, it never uses that, so I figured I would set it with code right after setting the location.
'set location before .show
Form2.StartPosition = FormStartPosition.Manual
Form2.Location = New Point(103, 449)

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?
When i close one window and open another using showdialog it shows back window or desktop for a while and then open the required one. I want to open directly without showing back window
View 1 RepliesI 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.

I call .show() and .hide() on a form and then I want to determine the current state. I've been checking .visible to determine if the form is visible, but I've stumbled uppon a problem. My form is being rendered inside a SplitContainer which I collapse each time I hide the form. So, by logic once I hide the form with .hide() it is no longer visible, and since I have collapsed it's container, even if I call .show() it would still NOT be visible couse it's container is closed.
So, how can I simply check if .show() has been called rather than checking if the form is visible.
The final goal is to show() / hide() the form along with collapsing / un-collapsing the container.
P.S.: I know I could simply check the container and show the form accordingly, but my form also supports detaching from the container, so that wont work for me.
I am writing a control application for an inteface card. The complicated work of initialising communication with the card is written and working fine. However, my problem is to update the text in a dialog label on the communication interface form from a module that contains all the coding for accessing the inteface card. From the module, the interface dll returns data that describes some typical connection errors and the module then calls on Public Subs in the form to display error messages; for example:This is the Public Sub in the Module that initiates communication with the interface card:
Public Sub OpenDeviceInterface()
DeviceID = 1 - My.Resources.DeviceID
h = OpenDevice(DeviceID)
Select Case h
Case 0, 1, 2, 3
[code]....
What happens when these Public subs are called from the module is that the MSgBoxes I made to test the routine show up but the label text doesn't appear.I've tried; Refresh, on the label and the form without success...
