VB 2008 - Change Child Form Combo Box From MdiParent Form
Feb 23, 2010
In VB 2008, I have a Parent form with a combo box on it. There is a child form also with a combo box on it. I want to be able to change the values on the child form based on what the user selected from the main form. The user launches the child form from a toolbar on the Parent form. The following code is run:
[Code]...
What I want to do is if the Parent's combo box has "Red", "Blue", "Green" values and the user selects "Green", the child form's combo box(With the same values) will also change to "Green". (I do not need to change the Parent form if the child form changes.) I've tried changing the Child's combobox from the combobox's change event on the Parent form, and the code runs, but nothing changes on the child form.

Has 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.

Anybody know a way to detect and set the form size in the child and MDIParent forms?
I'm having all kinds of problems from scroll bars popping up, to can't get the form to fill the parent. Pretty sure I have tried every possible combination in the forms properties 10 times.
I'm really getting tired of beating myself against this. Anybody seen a good tutorial on the finer points of MDIparent / MDI Child page size, etc.

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
Dim frm As New frmCalculatedResults

i am having an issue populating two combo boxes on form load. The program will connect to an access database and pull data as instructed. Then as it pulls each record it puts it into the combo box.
This was working.. atleast i think it was. i dont recall it ever not working, however i wasn't looking for it.
My problem is that if when i load the MDI parent form and have it skip the selection form and the login form and load the next form in the sequence, it loads everything perfectly. However if the select form is loaded first, then the login form and then the form i need loaded, it will not populate. The only difference between the two different loads is that the login form calls a function that loads the form as a new project.form
I did this so that I can have multiple forms open at a time. I am assuming my problem is that I need to get the child forms handle then populating controls using that handle? but i think if I had to do that then I would beable to populate the comboboxes on the first form load using the login method of opening the form.
Here's my code.
vb.net
Private Sub frmLine1t5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Text = "Line " & LineNumber & " Test Form"

I have a video control AxLiveLib.AxLiveX that displays video from a networked surveillance system. I'm trying to integrate this system into an MDI project, but when I set the form.mdiparent property on the form that has the video control, I no longer display video.I have a status bar at the bottom of the form that tells me connection status and current bitrate, so I can see that I am connected to the system, and if I comment out the 'FrmV.MdiParent = me' line on the parent form, I can see the video through the control.My question is what changes about the child form when you set it's MDIParent property? for example does the mdi parent take control over the forms refresh or draw functions?
code:
Dim FrmRm As New FrmViewRoom
FrmRm.RoomNumber = 1
FrmRm.Rec_NewMaxBounds = [code].....

I have a MenuStrip with File > New, Open, Save, Exit located in a parent form, and a RichTextBox located in a child form.The problem I'm running into is concerned with the destination of the file elected from "Open" and the save.When a user selects their file from "Open", I need it to open the child form and put the text into the RichTextBox.I also need the program to be able to "Save" from a child form, whether it's been brought up via "New" or "Open".

The following code does create a form within a form and does place NotePad inside the child form. You have to manually start NotePad prior to execution (I work on that later) but the code does workŠ My problem is now I want to manipulate the properties of notepad i.e. focus, size, location, etc. but I cannot figure out how to reference notepad and its properties.

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.

I 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
