View 4 RepliesI am using a tab control on my mdi parent forms. when i open a child window i hide the tab control. but i want the tabcontrol to show itself on child close event. but i cant figure out the code.
View 2 RepliesI have a program developed in VB.NET (2008) which consists of a MDI form and several child forms. It worked like a normal mdi application whereby mdi form acted like a container for child forms and things worked out okay. Code like Me.Mdichildren or Me.ActiveMdiChild etc could be used to get list of child forms and perform other actions.Now what happened is I needed to implement a tabbed system. There will be multiple tabs and forms would be in those tabs. So I added a Tab control in mdi form and now new forms are added to selected tab page. This way muliple tab pages can host forms and there is no need to see all childforms at once.
But a problem has come up. I do say ChildForm.MdiParent = Me (as before) but then I say TabPage1.Controls.Add(ChildForm).Doing so functions like getting list of mdi children or me.activemdichild or auto arrange options like Cascade,Tile Horizontal, Vertical etc are not working. This will be a major problem for me.
how can I check(with code) if an mdichild form is already opened or not. I have some mdichildforms that may open together. If an mdichild form is opened I want to dislpay the already opened form and not a new one.
View 4 RepliesI placed a button on my form that measured 59mm in width (approx 2.25 inches for any Americans).When you run the project as you'd expect it still measures 59mm.However when I set the form as a child to my MDIParent and run the project the button now measures 67mm (well over 2.5 inches) an increase of 13.5%.Is this a bug or do I need to just change some setting somewhere?

View 1 RepliesI have developed a small application. It has a MDIParent form on which the other childforms are displayed. I have a Panel on the MDIParent on which there are buttons to call up the MDIChild forms. Now my issue is, when anyone of the buttons on the MDIParents form Panel are clicked, it should check if another Childform is display, if it is then it (the active childform is closed) and the new form will be displayed. This part is working fine from the code below. However, when there are no active MDIChild form on the MDIParent form and if the button is clicked, the 'Else' part of my code below is executed. This generates the error as 'Object reference not set to an instance of an object'. So what is wrong with my code below?
Private Sub btnExecutive_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecutive.Click
Dim MDIChildForm As New frmExecutiveInfo

Looks like a dumb question, but I tried the following (where "Me" is a MDIParent form):

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

I have made new MDIChild and with textboxes on the form. When the form loads...it will open data saved from a text file to the textboxes. However the data does not load from the text files. When i take out the code, it works fine...but it needs to be a mdi child...the code i'm using is
Dim NewMDIChild As New ViewCustomer()
NewMDIChild.MdiParent = Main
NewMDIChild.Show()
the form that I need to load the info is "ViewCustomer" and the mdi parent is "Main"

how to minimize MDIchild windows to the StatusStrip...or is there another toolbar object in VB.NET (2008)? I have a menu layered over my MDI Parent window (which is always maximized) and if I minimize another child window, i can't see it anywhere (unless I minimize the menu too, but I took that ability away from the user)... I think I know how to do this through the menustrip at the top of the window (click on open windows....like in excel or word), but I'd like to see the windows minimized in a toolstrip of the MDI parent.

I have a main form with a number (in this case 9) mdichild forms. Some are visible, some not, but they are all very basic. When I write to a textbox in any child form during Main_Load it updates, when I write to a textbox in any child form inside its own _Load it updates. If I write to one from awhere else in code, including a sub in the form's own code, it fails to update.
All the child forms are identical but are distinctly separate forms created before compilation rather then NEW versions of a single form to avoid threading problems.Curiously this code worked once only. No edits were made and when re-ran failed after stopping it if found all the controls in some of the forms were invisibe in developer mode, restarted VS but still not there. Run app and at runtime there they were!!! Also all locked textboxes still accepting input.

I'm making an appication that needs to maximize the window of another application. In Spy++, the way it works is -> "Working Model - Untitled1" -> "MDICloient" -> "Untitled1"This is what the tree view looks like.I need to maximize Untitled1, but I'm not sure how. I tried findwindow "Working Model - Untitled1" and then used get and setwindowplacment for it, and it worked. Then I used findwindowex on "Untitled1" but it did not maximize. What am I doing wrong here? I'm sure mdi windows can be maximized; the "Untitled1" window itself has the 3 buttons (- + X) on the caption bar.
View 1 RepliesI have a big problem regarding MdiChild. My problem is that I have 3 forms loaded;
Form1=Mainform / mdiParent
Form2= Display the Datagrids
Form3= This is where I let the user input the necessary fields like Lastname, Firstname,Age,etc...
My problem goes like this, Form3 is the child of Form2, Form2 is the child of Form1 and I call them one by one like this:
//form1
Form2.MdiParent = this;
Form2.Show();
[code]....
I want in the Form3 to save data and refresh on my datagrid on Form2 so that every data that I encoded in Form3 will reflect in Form2. I let the Form3 close everytime there is data entered but my problem is that the data that entered doesn't reflect in my datagrid.

I have a module that handles adding controls and populating values on a form. One of the controls is a button (there can be many) which acts as a lookup. For some reason, when I click the Button, it winds up in the btnLookup_Click event and displays the various messages, but it does not update the label (labLookup) text on the form. Am I missing something?
