Inter-form Communication - Form Being Called Form Several Forms Using ShowDialog()
Mar 28, 2011I 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?

Form Called FrmPracDetails Which Is Built Up With A List View Called LvwColProc
Aug 11, 2009I 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 RepliesSet Calling FORM Visible = False By CALLED FORM
Sep 6, 2010Requested 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.

How To Know Which Form Called Another Form
Jul 31, 2010I 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 RepliesDetermine Which Control Called A Form?
Mar 3, 2010I 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 RepliesForm's Load Event Not Called?
Apr 25, 2011I 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?
DataGridView - Won't Populate Second Time Form Is Called
Jan 28, 2011I 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.

Check If .show() Has Been Called Rather Than Checking If The Form Is Visible?
Apr 22, 2012I 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.
Public Sub Label Changes On A Form Don't Work When Called From A Module?
Dec 15, 2009I 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...

VS 2008 : Updating A Data Base File Via A DataGridView Control When Called From Another Form?
Jul 24, 2011I am sorry to keep bothering you about this damn DataGridView control ... As you might have noticed I am having a hard time with the DataGridView control ... My latest problem has to do with updating the data base file (Access) through a DataGridView control .
Up to now I have managed to successfully edit an entry in the DataGridView control and moreover to successfully update the data base file itself .
The above form and its code work fine . The problem starts when I am trying to run the code of the Update button from another form .
You see , I have another form , through which I change the contents of some of the cells in the DataGridView control (back in Form1) . What I want next is to simply update the data base file itself , just like I was doing with the button in the first form , after I manually changed the cell in the DataGridView control .Thus , on the second form I have a button with this code :
Form1.Button1_Click(Nothing, Nothing) (of course the Click event is declared public)I have also tried :
Form1.Button1.PerformClick()
but still nothing ...Although Form2 successfully changes the cells back in Form1 , the data base file itself does not get updated ...If I manually press the Update button in Form1 I once again successfully update the data base file , but I want to do the whole thing by calling the Update button from Form2 .

TopMost Form - Messages Form Would Be Hidden By The Main Form
Nov 20, 2009I have a tool window that I want to stay above the main application form, but not stay on top of all windows forms. Similar to the floating properties window for visual studio - it always stays on top of the main VS window, but if I select another program, like internet explorer, the floating properties window will be behind internet explorer.
What I have is an application that has several forms that may be displayed at the same time. I have a Messages form that displays messages generated by the code in the form, that gives the status of the application. Obviously, the user would not normally be working on this form, but they may want it to be visible to see the status messages from the program (File saved confirmations, etc). So, my two options right now are I can set the form to be on top of all other windows forms or, when the user clicks on the main application form, the messages form would be hidden by the main form.
