MDI Child Form Not Opening Correctly
Jun 24, 2011
I have an MDI form on which I am trying to open two other forms in the same place (not at the same time). One works, one doesn't. Both of these forms have the following as the very first statement in the load event.
One form opens in that location and functions fine. The other form, which is the same size, seems to spread out across the MDI form top-to-bottom wise. There is also a bar at the top with min, max, and close buttons that came from where I don't know as the form is set with no border. This form must open in the correct way as there is a menu at the top of the MDI. Anybody have any idea why this is happening? Some property or something which is different between the 2 forms?[code]...

I have an MDI form with child forms which I open on it. The following statement in each form's load event places a child form in the location I want:
Me.Location = New Point(0, 136) I have several of these working. However, I have one form for which this statement does not work. It opens spread out over the entire parent form. Also, there is a border at the top with min, max, and close buttons even though the form has no border. This form has a picture box on it, if that means anything. why this child form does not open in the specified location?

We have a main form which opens an MDI child form. What we want is to set the focus on a particular control in the child form, namely a telerik textbox. When the form is opened for the first time, the focus is set to the textbox control which has a tabIndex = 1 as expected. If the winodw is closed (and disposed) and then reopened via a button on the tool bar that calls the same code that opens the window when the application starts, no control has focus. We have added lines such as Me.rtxtPatientId.Focus() in the Paint event, load event, and activated event handlers but still cannot get the focus to the control. The code is quite extensive so posting it is difficult. However, here is the section that opens the child window:
if PatientSearchForm Is Nothing Then
PatientSearchForm = New frmPatientLookup
End If
PatientSearchForm.MdiParent = Me
PatientSearchForm.Show()
If PatientSearchForm.WindowState = FormWindowState.Minimized Then
PatientSearchForm.WindowState = FormWindowState.Normal
End If
PatientSearchForm.Activate()
PatientSearchForm.rtxtPatientID.Focus()

I'm creating an application that uses an MDI container to create a sort of desktop style for my form with a group of icons docked to the left hand side. The rest of the form is the desktop area that I want all windows to open in.If I use the standard File-New option that is provided by VB as a default for the MDI container this works fine and a child window is loaded.If I use similar code from one of the icons this also works fine.y problem is that one of my child forms is a search panel and when I double click on one of the results I want a window to open, but as an MDI child. However, this doesnt happen. When I open the window it opens as a completely separate window and isn't docked within the MDI parent. It also appears on the task bar as a separate application.

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".

I have a program that will let you open a certain table in the database and query it on a child form in a MDI parent form. Of course the child form is a new instance of an existing form.The thing I want to do is that the opened table in the child form cannot be reopened again in the other child form. So I did was to create a childform name on every new instance of a childform depending what is the name of the table.
The first thing I did to do this restriction is to put the names of the opened table to an public array and when the user tried to reopen the table, the program will check if the childform name is already existing... and if it exist it will not let the user to open the table in new childform.When the childform is close it will erase it's name to the public array. And it can be open again.If you don't understand what I want to do this is the situation for example in a microsoft office when a word document file was open it will be put in a childform, and when the user tried to open the word file again and still the word file is open in the microsoft word the application will tell it's user that the word document file is still open.

It is my goal to write a program to run a retail store. I am an intermediate Access developer, so I have a good grasp of the basics.However, I find that developing in VB 2010 is quite different.I will have forms for:
Company Information
Employee Information
Supplier Information
Customer Information
Invoices & Purchase Orders
All I really need to know at this point is the code to open and close each form.

I have an MDI parent screen that loads on startup and a lot of child forms that load when opening. So as the child forms load there's a lot of flashing and it looks really ugly. Once they're loaded all I have to do is use a bring to front, maximized command and it works smoother than closing a form and opening a new one every time a different form is selected. I've tried creating a splash screen, minimizing the forms on load, etc and everything still works in order so first the splash screen then the forms load.
How would you set it up so a splash screen stays on top of all other forms for like 5 seconds while the forms load in the background without seeing them load? Right now the screen shows then when it's done it moves on to step 2 which is loading the child forms. If no splash screen, how do I make it load so you don't see all the child forms opening at once?

I have a single form called 'FolderSelector' with a label, textbox and a button.The problem I'm having is that everytime I run the application, the only thing that shows up is a blank form called 'Form1', the program runs everything it should do except to show the actual form which is really weird.Here's the code in case there's something in there that's causing it that I haven't spotted.
Imports System.IO.Directory
Public Class FolderSelector
Public Const SPI_SETDESKWALLPAPER As Integer = &H14
Public Const SPIF_UPDATEINIFILE As Integer = &H1

Note: I am working with Visual Studio 2010 Professional. Note: There are a lot of MDI Child posts, but none (that I have found) that apply to my scenario... Scenario I have an MDI form with a UserControl docked at the top. The UserControl is for navigation and is ~50 pixels in height. When I show a child form with its WindowState property already set to 'Maximized', the child form shows maximized in the MDI parent, but behind the UserControl.

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 work¦ 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 have a question that I hope to find a much more simpler solution to.I have two forms in my program which are named Main and Second. The Second form has several textboxs, buttons (some disabled) and comboboxes. When the Second form is opened via the Main form on the very first instance, everything works fine.
However, if I re-open the Second form after previously closing it, the disabled buttons are no longer disabled and the text controls and comboboxes show the previous values entered from the first instance which I do not want. How can I ensure that the Second form will be opened "clean" every time.
Currently I have to add instances to the onload event to do this to ensure that the form is cleared on the second instance.textbox1.text = ""textbox2.text = ""textbox3.text = ""button1.enabled = False

Is there a better way to make a form with multiple buttons opening different things than having a form that has lots group boxes for each tab. So in the begining each box will be invisible and when you click the button the corresponding group box will become visible. Is there any other way?It will be like a background image and it'll have buttons that will mask it with invisible buttons. when the button is clicked it will open the corresponding group box.

I have a txt box that askes a user to enter his email address and I want to make sure the user enters a correctly formatted email.
The code I have so far is like this
If txtEmail.Text = "" Then
txtEmail.BackColor = Color.Pink
MessageBox.Show("Please Enter your Email")
Exit Sub
Else
txtEmail.BackColor = Color.White
End If
How I can modify this code to make it work and is regular expressions the same for all programming languages? Also for my mobile number text box I only want a user to enter a 10 digit number with only integer numbers.
The code I have so far is
If txtNumber.Text = "" Then
txtNumber.BackColor = Color.Pink
MessageBox.Show("Please Enter your Mobile")
Exit Sub
Else
txtNumber.BackColor = Color.White
End If

I have been working on a quite complex multiform solution.All of a sudden the start up form (in fact any form I designate to start up) loads, displays and operates fine.
But when I try and show a form using showdialog the form displays behind the original form and I can�t set focus to the ide to close it down. I have to use task manager or alt f4 while the form has the focus.
Calling different forms from this one gives the same result but other forms work fine. I don�t want to redo this form as Ive done a lot of work onit.The only thing I can think of that whist I was changing the startup form in the project propertied page (file>project>properties) I unchecked the �Enable applications framework checkbox.
