I build my first Project composed of several forms and it�s working just fine. Id like now to redesign the project as a MDI Application. Once created the parent form, I can create child forms but thats not what I need. What I would need is convert my already designed and working forms to MDI child forms. How can that be done?

View 1 RepliesI have made a project on Library management system using Microsoft Visual Studio 2008 and Sql server 2005 .I have used MDiParent form in this project, from where I can click on the menu item to open the desired form.
I am now able to open the child forms in the main window background.Now what happens is When I click on one menu Item it open in the parent form background.I am able to open all child forms corresponding to the click event in the MenuToolStrip ...all in the Parent form Now the problem is that I cannot minimize child forms when I minimize Parent form..I want child forms also to minimize along with the Parent form.. Also are child forms still not attached to the parent Form is also my question here.....
Now I need to avoid exception error for when I move, minimize and close any of the other 3 forms for the program I am building. ZOrder?. I was thinking of using an if statement to determine the zorder of each form. I need to know how to implement the if statement.

View 3 RepliesI am re-doing part of a GUI for my project, The Windows Alias Generator, and decided to switch to MDI. The child forms consists only of RichTextBox1. Here's the generate routine called when the save is clicked:
Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles SaveAsToolStripMenuItem.Click, SaveToolStripButton.Click
Dim ActiveMDI As Form = Me.ActiveMdiChild[code].....
But because I cannot define richtextbox1.text from the currently active MDI, I cannot use this routine...my question is this: How would I get RichTextBox1.text from the save option in the MDI form?
I have a MDI child form with its own menus. (TestForm)When I call the child form (Testform.show) from the parent form menu, the MDI Child form's menus are appended to the container form..Essentially, the container form steals the menu of the child form..
View 2 RepliesI have a MDI parent on which i launch a child form
Dim NewMDIChild As New Frm_addOT
'Set the Parent Form of the Child window.
NewMDIChild.MdiParent = Me
'Display the new form.
NewMDIChild.Show()
His child form contains several comboboxes which hold data from a dbase(sql)
When new data is entered in the cmb it checks the database and if it isn't in there it launches another window
FRM_OTlistaddklant.Visible = True
and copy's the newly entered text in a textbox.
FRM_OTlistaddklant.TB_klantnaam.Text = OTaddklant_naam
then i can give in the details etc.
now, when this is done and the users presses a button "Add"
the information is written to sql(which works perfect)
than i have a public sub on the Frm_addOT which should refill the combobox and
also set the backcolor to a specific color.
and the last two things will not work. Actually when i try to change the backcolor on Frm_addot it triggers the event backcolorchanged and says it has changed but it is not visible.
Has anyone ever had or dealt with resizing issues on MDI Child forms? I am working on a VB.Net Windows applciation project I inherited from another devloper. When I took it over the forms had already been designed. There are one MDI Parent Form and two MDI Child Forms. When the application starts up the parent form and one child form open by default. Both the parent form and the child form will maximize, restore, and minimize. Although I have to move the parent form slightly, when it is not maximized I can resize it with the mouse pointer as expected. The child form will not resize and when I move the cursor to the border of the child form I do not even get the mouse pointer. Also, when both the parent and child form are maximized the vertical scrollbar on the child form is no longer displayed.
One potential problem is that there are lots of controls on the child form, which are inside several group boxes. When I comment out the controls, the blank form displays without the vertical scrollbar but will resize with the mouse pointer as expected. When I uncomment the controls the resizing does not work any more. The AutoSize propery on all of the controls is set to True. I tried commenting out the code setting the Autosize property to True on the group boxes only. The result of that is that the resizing still does not work and I lose the vertical scrollbar.I am trying to avoid having to redesign the form completely, however I am running out of alternatives. The project will not pass UAT if the resizing does not work.
I'm just getting started in VBE 2008 porting a VB6 program and have created the MDI Parent form. I've added a form called frmNav and need to designate this and all subsequent forms as MDI child forms. Is there somewhere in each form's properties where I designate this? It used to be in VB6 there was a property called "MDIChild = True." input id="gwProxy" type="hidden"><!-- Session data--></input> <input id="jsProxy" onclick="jsCall();" type="hidden" />
View 1 RepliesIn VB6, MDI applications were possible. You'd create a form and a few Child forms and go with it.

View 12 RepliesI have some VB.Net WinForms I imported from VB2005 that are MDI Child forms. In the old project the clipboard shortcuts work (Ctrl-V, etc.) but in the VS2010 project they do not. the ShortCutsEnabled property is true.Any way to get these working again without adding special code to replicate the feature? I have a bunch of forms to convert....The parent does have KeyPreview but I can comment that out and the problem still exists. I also hook the TextChanged event for dirty logic but I can comment that out also to no avail.
View 6 RepliesI have been looking around at how I can close my parent form and my child form. This article: [URL] has some information but it either doesn't work for me or I am putting the wrong information it. What I want to happen is when a button is pressed I want to close both parent and child forms and then go to another form (frmResults). Then there will be a button on frmResults that will take me to the beginning form (frmPTCalculator). With this code below when I click the button on frmCalculator it goes to the MDI form and both parent and child forms are there.
my Parent form is called: frmGender
my Child form is call: frmMale & frmFemale
Below is what I have tried from the example in my Child form frmMale:
Private Sub btnResults_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResults.Click
Dim frm2 As frmMale = New frmMale()
AddHandler frm2.FormClosed, AddressOf frm2_FormClosed

VB.NET 2003 makes it difficult to have a child button create an event on a Parent form control. I would like to change the state of a control on the parent form by using a button on the child form.

Is there any chance to pass values from mdi parent to mdi child.
View 1 RepliesIn all my post I have explained I am a total novice so a little more elementary explanation is normally required in my case. I have tried reading the explanations about Parent and child binding but just cant get it to work.This is what I have:
A parent form called Sites Primary key is pkSitesID Various other fields On that form I have placed a tab control and in page one I dragged SitesInstallation to it there is a relation created in the DBDiagram to link fkSitesID (in the sitesinstallation table) and pkSitesID
All I want to do is when I navigate through the Sites records the data in the tab page changes according the values I have selected for that given site.
For example: The Siteinstallation maybe Pending or on air.
I 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.
Do I have to manually call Dispose() when a MDI Child Form is closed? The MDI parent must call for Dispose() or inside the MDI child the call is made?
View 5 RepliesI have an MDI window with multiple child forms. The user can hide or display child windows by checking/unchecking in a View menu on the main form, calling on either the Show or Hide methods for that form. Each time I call the show method do I also have to specify myForm.MdiParent = Me, or do I only have to specify that once, ie does vb remember that the form will always be a child? it doesnt appear to be a form property any more (from vb6).Second question relates to forms themselves. If I have created a form at design time, is it more efficient to create an instance of that form using New, or simply show the form as it is by just loading it.What are the pros or cons, memory and speed wise? In my case I will never need more than one copy of that form to appear, I'm using VB2005.

View 2 RepliesSo I've just discovered the little "bug" - I hope, when adding forms to another form. If the form in question behind added to another form contains a textbox. Then that textbox will behave in a no way normal fashion. It seems it has no response with the mouse. Yet keyboard interactions are normal. For example, using the mouse your unable to move the caret around or select any text at all. Simply you can double click - which highlights all the text, or clicking once which gives the textbox control focus, just the caret remains unchanged(to the far left most position).
This topic was difficult to locate through google, so I've tried some research before posting this. All examples I found were C++ and no one seemed to understand the OP's question.
Mine is how can I work around this? I've tried all suggestions I've found so far but none have worked. At this point I'm thinking my ONLY suggestion is to create my own textbox control, as I've already created a collection of controls, wouldn't hurt to add textbox to the list. But this would be time consuming and a lot more work. I'm not even sure if this would fix the problem if the problem is internal..
