I have a MDIParent form that has a bunch of child forms. When I open a child form, I can actually move the form outside the bounds of the Parent. How can I prevent this? I've set each of the Child Forms "IsMdiContainer" property to "False". What am I missing?
View 1 RepliesI would like to display the autoscroll bar on MDIParent form when user moves MDIChild form. I set the autoscroll to false on the MDIParent form, but it does not display the scroll bar. What should i do?
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):
Dim frmNotif As New frmNotifica
With frmNotif

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:

View 4 RepliesI 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 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.
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 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 2 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.
Using a plugin architecture, i created a Form Class that holds the Mdi Form. it has menustrip, toolstrip and statusstrip.
child forms are created as class and are loaded into the Mdi Form at runtime.
using interface, i was able to execute subs and functions of a child in the Mdi Form and vice versa.
now i need to change property values.. to be exact, i need to change the enabled property of the toolstrip buttons depending on which child form is activated using the form_activated event of the child form.
the problem i now have is how to change the property of the toolstrip item in the Mdi Form.. should i be using interface on this as well by creating subs in the interface and have the Mdi Form implement this interface?
I`m developing a desktop application using Visual Studio 2005 and a vb.net code.I`m using one MDIParent form 'frmMDI' and about 20 Child Forms. In the frmMDI there is a MainMenuStrip that contains 20 ToolStripMenuItems each one used to load a corresponding child form through this [code]So, that code is responsible to load a child form. Now what I`m facing after the loading of the child form is that the behavior of the controls of that child form is not so normal. you can`t set the cursor to the end of the text in a textbox.
View 17 RepliesI have this function
Private Sub createChildForm(ByVal winForm As Form)
'Take a form and set app as its parent form
winForm.MdiParent = Me
winForm.Show()
End Sub
When some one wants to view the "About" form, it's called like this:
createChildForm(New f_about)
But my function doesn't stop them from creating an unlimited number of about windows and I need to put that limit to one form.
For example, I will have a login screen, but I don't want them logging in over and over again in different accounts because my subroutine doesn't stop a form from being created/opened more than once.
How run a program inside a MdiParent?
View 5 RepliesHas anyone had any luck with having different window states with multiple open child forms?for example if you have a single child form opened and say it is maximized.then open a second child form as normal, the first form will then be set to normal.all the open child forms will mimic the newly opened forms state.and i believe they will mimic when making some changes to one forms state.the others will follow.i have not had luck keeping this from happening in most situations.

View 3 RepliesWhen i try to view MDIParent screen in designer mode I'm getting below exception...
`Could not find endpoint element with name 'NetTcpBinding_IMyService' and contract 'ClientProxy.IMyService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.'
Little background to understand my question more clearly...
I've a WCF server which I'm trying to consume in my Winform application. So i've created a separate class library in which i added service reference and created a proxy. I've copied the client endpoint info from app.config in class library to UI app.config file.
When i run the application everything is working fine but when i try to open MDIParent screen in designer mode its throwing above exception.
Note: I think i'm getting error because i'm trying to create a proxy object on NEW method (form constractor) if i comment that line - i'm able to view designer screen.
I'm tired of looking at the boring default dark gray back of an MdiParent. I tried using Juggalo's Gradient Form and realized that the MdiParent was not being painted, at all. A temporary work around was to create an Image and set it as the background. This is fine and dandy but when I bring the thing to full screen and drag around my MdiChildren forms, the application gets laggy. I have already tried setting the Form to Double Buffered and it doesn't work at all, no noticeable change.I did try editing the Form's Paint() event, but to no avail.Here's the code I'm using to create the image (practically from Juggalo's Gradient Form):
[code]...
Creates the image nice and fast. I want this to happen in the Form's Paint Event though, so I don't have to rely on an Image that causes my program to lag about.
