I have a mdi container thats got 9 forms running in it.When I minimize a form it minimizes into a small "window" in the left-bottom corner of my mdi-container.
How do I change this so that the forms will minimize to the Left-TOP corner of my mdi-container?
I have a basic form with four objects placed on it: a Menustrip(Dock = Top), a ToolStrip(Dock = Top), a SplitContainer(Dock = None) and a StatusStrip(Dock = Bottom). As it is now, the MenuStrip, ToolStrip and StatusStrip are exactly where I want them. The problem occurs when I set the SplitContainer dock property to Fill. I thought it would fill the remaining area but it fills the entire form, you can see the outline of it beneath the menu and status strips. Is there something I'm missing in another property box or is there a different way of doing this? The reason I want to set it to Fill is for autosizing when I resize the form.

VB2008 I have a panel in which I draw some graphics. Parts of the codes which I have successfully wrote & drawn are shown below:
Dim scaleX1 As Single = CSng(Me.pic_pcg.Width / 1.355)
Dim scaleY1 As Single = Me.pic_pcg.Height / HGT
'
e.Graphics.ScaleTransform(scaleX1, scaleY1)

I want to add some labels and textboxes in the panel so as to add remarks & captions to certain parts of the graphics.How do I set or modify the "scales ?" of the locations of these labels & textboxes so that they will be placed correctly, corresponding to the above scaletransform/translatetransform/rotatetransform.
I'm trying to make an MDI TabControl Container usercontrol, which is used instead of the MdiClient control in an MDI application. Instead of MDI Forms, you can use (modified) TabControls that behave like (maximized) MDI Forms in a Tabbed environment.
A great example is of course the Visual Studio IDE. Each window is just a TabPage on a TabControl (at least it looks like it is, I don't know exactly how it works in the IDE.. but let's assume it is).Now, the VS IDE uses some great functionality which I believe is called TabGroups. By Right-clicking (or dragging it into nothingness) a TabPage 'header', you can choose New Horizontal / Vertical Tab Group, which splits the 'container' into two TabControls, each with their own TabPages, with a splitter in between so you can resize them.
I have been trying to recreate this behaviour, and I must say it works pretty well so far for very little effort. The only (major) downside is, it only works for Vertical OR Horizontal TabGroups. I have no idea how I can possibly make it work using both vertical and horizontal TabGroups simultaneously...
What I did is pretty simple: I have a mdiTabControlContainer which is just a blank UserControl. I made a public property TabControls that returns a (custom) mdiTabControlCollection (inheriting from a generic Collection(Of mdiTabControl) which is basically just a collection of my tabcontrols.
When the collection is modified, I call a RedrawTabControls method which first clears the Controls (deletes all TabControls), and then adds them one by one. First the last in the collection (docked Fill) then the rest docked Left. I also add a splitter between each TabControl. (Code at the bottom)If I dock the TabControls to "Top" for example, I can make it Horizontal. But I have no idea how I can possibly dock a few of them to Left and the other few to Top...? I would need some kind of property that determines which TabControl should be docked where, right? But how and when would I set that property?
The code I'm using now is:
vb.net
Imports System.Collections.ObjectModel
Public Class mdiTabControlContainer
Public Sub New()

I've two forms Form1 and Form2, I want to add container(*) in form2 having toolstrip(Toolbar) and later want to display that container(containing toolstrip) in Form1, that enable the user to use toolstrip to execute needed actions written in form2.

Am devloping an application with multiple forms, which reside on top of a main form. i.e the main application window. The 'child' forms do not need to be linked in any way as they do not pass information to the parent form, as all the parent form does is act as main window.Now I would like to know what is the correct way for the 'main window' form acting as a container for the other forms? So that all the smaller secondary forms stay focused on top of the main application form, that when the main window is minimized, so these forms should do also etc..
I have read other posts and they mention, leaving all the forms standard i.e. IsMdiContainer = False and then using form.showDialog() to call the secondary forms. This did not work for me as what happens is that as soon as I give focus to the main app form, the secondary form disappears underneath.I tired making the main app form IsMdiContainer = True and when it loads calling:
frmMemberForm.MdiParent = Me
Now this works, because I can click off the form and minimize the app etc and the frmMemberForm doesn't disappear. However if i close the MemberForm and reopen it, it looses this property and once again when it looses focus, it will disappear.
I am trying to extend the functionality of the ToolStripPanel control (which is a panel hosting ToolStrips that can be moved during design-time, as I'm sure you know).One thing I wanted to add was a 'ToolStrips' property, which would be a collection of ToolStrips the user can edit via the collection editor in the designer. So instead of manually placing ToolStrips on the ToolStripPanel via the toolbox, the user can just use the property to add/remove (or even edit) them. This is of course similar to how you add/remove/edit TabPages in a TabControl.So, I came up with this code, which I have used successfully in the past for other controls:
Public Class cToolStripPanel
Inherits ToolStripPanel
Private _ToolStrips As New ToolStripCollection(Me)[CODE]....
The cToolStripPanel control inherits the ToolStripPanel control and adds the ToolStrips property, which is of type ToolStripCollection. That class, in turn, inherits the Collection(Of ToolStrip). In the InsertItem method, I add the 'item' ToolStrip to the cToolStripPanel. Of course I also need to override the RemoveItem / ClearItems methods but that's for another time.I am 100% sure that this code should works, at least for other controls. If you replace ToolStrip with Button (for example), I can add buttons via the property during design-time just fine, exactly the way I want it.But it seems that ToolStrips are special. When I try to Add a toolstrip (via the collection editor Add button), a null reference exception occurs. I've been trying to debug this all day and I've finally come up with a possible candidate for the problem... (I've actually used design-time debugging for the first time ever, which was pretty cool, and which showed me that the InsertItem method is not run!)
I think the problem is that the collection editor cannot create a new instance of the ToolStrip class. I can remember when trying to inherit from the ToolStrip, I was forced to add a constructor, because the ToolStrip "has more than one constructor that can be called with no arguments".Perhaps this is causing my problem? Do I (and if yes, how?) have to somehow control the creation of a new instance of the ToolStrip? Or am I completely off track and that is not what is causing the problem? I'm sure that it's a problem with the ToolStrip class, since I can use the exact same method with other controls just fine. It's only when I change the type to ToolStrip that it starts getting angry at me....
I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.
When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.
I'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)

I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!

View 7 RepliesThis is more of a ASP.NET question, but we are using VB.NET so it might be relevant. We just recently upgraded an ASP.NET 1.1 project to 4.0.Once we started running through the app to regression test it, we found that (consistently) if we made a call like DataBinder.Eval(Container, "PropertyName") from a User Control, ASP.NET complained that it could not find the PropertyName on the page.
PropertyName *does* exist on the User Control, but not on the page.This worked up until we upgraded to 4.0.The fix we found was instead of using "Container", we used "Me" to reference the control that the code was being called on.
start a desktop app. make the form 1- MDI Container = True. 2- Right to Left = True , 3- change the Right to left Layout = True.Set the background to any jpg image, when you run the form, the backgroud disappears.
View 3 RepliesVB 6.0 had a Set Pixel function, which is not available in VB.net. using a draw ellipse function with parameters specifying a circle one pixel in diameter.The above is painfully slow.I have been drawing graphics in a Bit Map using a Set Pixel function & then copying the entire graphic from Bit Map to a Picture Box. This results in nothing seeming to happen for several seconds & then the entire graphic is displayed in the Picture Box.
The above does the job, but it would be nice to display the graphic as it is being generated pixel by pixel, which was possible using VB 6.0, Might there be a Windows 7 API which would set a pixel? Might Microsoft be considering a Set Pixel function for Picture Box graphics?

In my program, I want the user to be able to move an MDI child window anywhere inside the MDI container but I need it to be kept completely inside the container boundary. For example, the upper left corner should never be at a location less than 0,0 when moved left or up. Currently, if I slide the child window too far left, it extends outside of the MDI container window and the MDI container shows the bottom scroll bar.
Is there a way to prevent the child window from moving outside of the boundaries of the container window? I tried adding code to the .move (see below) so that if the new location was less than 0,0 then it reset it to 0,0 but then the child window controls flicker as the window is moved beyond 0,0 and the logic moves it back to 0,0. It appears that even though the code changes the location to 0,0 and the window shows the child moved to 0,0, when the mouse moves again, the window jump back to its unmoved location.
