Accessing Datasets Loaded In Main Form From A Child Form?
Aug 11, 2009I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.

Jul 31, 2009I have a form where I open an Access database with 3 tables. I have defined datasets and dataviews for these three tables in the main form. I want to open a new form and access and update the tables using the dataviews I've already defined. When I try to access a record from the dataview using the new form, it's not defined. Can I pass the data between forms or do I need to redefine it in the new form? This is the first time I've tried to use multiple forms.

Jul 18, 2009Basically what I need to do is change a textbox on Form1 (AKA mainwin) from Form2 (AKA loginwin) using data that is inputted into Form2.

View 1 RepliesVS 2010 Accessing Same Form But For Different Actions?
Jun 12, 2012I have a datagridview on a form and this shows up my list of suppliers. I have a textbox which when i click shows up the supplier list and from there when i double click on a row, the supplier's name is shown in the textbox. The thing is i have to do same on the same page for search purposes which got its own textbox. But the cell double-click event already contains code that will display it in some other textbox like i mentioned previously. What i thought is to make another form with a datagridview. So this datagridview will be used to display the supplier's name in search textbox. But what if i have to access this form several times. Do i have to create several forms everytime?

View 1 RepliesAccessing Multiple Form Controls Using A Variable For The Name?
May 23, 2012I'm trying to iterate through a group of ComboBoxes and set a property using a concatenated string & variable to represent the name of the control. However, I can't get the instance of the form to recognize the (String & Integer_Variable) as one of its controls -- and so it doesn't recognize any of the appropriate properties or subroutines as members of the System.Windows.Forms.Control.Is there a cleaner way to do this?

User Control Accessing A Form Within The Project?
May 1, 2010I have a "windows form" user control--that is, not on a web page etc. This user control has a form within the user control project. However, code from within the user control can't 'see' the form even though it is a public class---I don't understand why this is the case.
So how can I access the controls (a couple of radio buttons) on the form from code within the user control? I tried creating public properties on the form to return the state of the radiobuttons, but this still doesn't work. I get a "Reference to a non-shared member requires an object reference." error
Should I not be able to see the form since it is a public class?
VS 2008 Accessing The Controls On A Form Which Is Not Created?
Jan 30, 2011When I try to access the controls of a form which is not yet created (i.e. to modify the contents of a text box , to press a button etc) , I fail , usually without even an error message . I found out that the only way to make my program go right is to take care that the form is first created before I try to access anything on that form . However this means I must use the Show method to create it and then to Hide it , which leads to an instant awful optical effect . I remember back in VB6 there wasn't such a problem ; it seems that in VB6 each time I accessed a control on a not-created form led to the form being created silently . Is there any way I could do that in .NET too in order to access my precious controls ?
View 15 RepliesVS 2010 Difficulty Accessing 'disposed' Form?
Jan 18, 2012I'm having a strange difficulty. Here is the order of events:User presses button on form1 New Form object is created for from 2 New form object '.show' command is fired Form 2 opens correctly In the Load Event of Form 2, the form attempts to do various things in a try, catch, finally clause On catch, I close form2 down '.close' as it cannot be used as something has gone wrong with the execution However, my problem is this. It is acceptable for things to go wrong on the from 2 load event which is why I have implemented the try - catch functionality. However, when I close the form2 down as a result of the problem, a real error ocurrs 'Cannot access a disposed object' and the VB IDE refers me to Form1's '.show' event for Form2.
It is almost as if the form hasn't fully 'shown' before I am closing it down. Does anyone have any idea what the problem is here? Do I need to close down Form2 ourside of it's Load event handler so that Form1 thinks it has loaded correctly?
Accessing Function In Alother Class From The Main Form?
Feb 12, 2011I have a new solution with 5 projects inside. a data access layer, database, 2 class libraries, and the main form. These are all components that I had worked on to get to this point of combining into 1 solution. Now what I have run into is I can not the actual functions in the class libraries. I can get to the class level, but that is it. ere is a sample line of code I need to get working. Once I get this one line, the rest will be obvious: Temperature is on the main form. get for options is "Equals, GetHashCode, GetType", etc... Before this I had bult, compiled, and referenced these classes separately, and it worked fine. I know this is going to be an easy answer, I'm just not seeing it for some reason.

Mar 1, 2011I'm writing a really simple file updater which downloads files off from a website and saves them. The download routine is working well, except that it freezes the project while attempting to connect to the host. Easily solved with threading except now when I try to access other form items such as text boxes, labels, form caption, it says I am not doing it in a safe manner and prompts an interrupt in debug. I did some reading on it and I'm still not sure what to do, I'm very new to vbnet and it is still a little confusing to me.
