I'm making an MDI child window switcher (to set focus on selected child) sort of in a windows-style taskbar at the bottom of the program. I've got things set up so that when a child window is opened, a toolstripbutton is created and added onto the toolstrip and contains the window number and window type (what the window does). All that runs very well, but when I want to close a child form, I need to dispose the button that corresponded to it. I tried something like this:
For Each C As Control In frmClient.Controls
If TypeOf C Is ToolStrip Then
For Each tButton As ToolStripButton In C.Controls
[Code]....
But nothing happens at all. Is there a practical method to do this or am I missing something?
I am dynamically creating 12 picture boxes then click next and dynamically create the next 12 (in place of the first 12)
From what I can tell it is creating the next 12 I just can't see them. Do I first have to dispose of the original 12 first? if so how do I go about disposing of them?

There to all gurus,I'm trying to build an Excel generation aplication using VS 2008 and Microsoft Excel 2003, but some how the Excel process that i create it's stuck in the computers memory, and it's only removed when I END the VB Application.
I am using Direct2D and the speed is so much better than gdi.however when i call the Dispose method of a D2DBitmap object no memory is freed up even after a garbage collection
so i guess my question is how can i properly dispose of a D2DBitmap object?
I have a user control that inherits the FW ListView and I need to dispose of two objects when the form's disposing of it's objects. Here's what I've concluded already, am I on the right track?
I have a toolstrip in my main form, at the bottom. The main form has menus that lead to other forms. I am trying to get a button to appear on the toolstrip each time a form opens. My button creation code works. Here is what I have so far:
Public Sub buttons() 'Each form has a Me.FormClosing and MyBase.Load event that links to this sub. ToolStrip1.Items.Clear() ToolStrip1.Items.Add(ToolStripDropDownButton1) For Each frm As Form In My.Application.OpenForms
[Code]...
I have tried using the Tag property to choose the form, but it hasn't worked.I have also tried using the My.Application.OpenForms property to open the form, but this also hasn't worked.I really don't fancy using loads of If Then Else statements to hide and show buttons that have already been created, as this seems rather messy.
I have a textbox, a standard button and a toolstrip containing a couple of buttons. In the validating event of the textbox i coded to check whether it is blank. If yes then it shows a message 'Enter Value'. When the standard button is clicked while the textbox is empty, it's validating properly and showing the message but when the toolstripbutton is clicked it's not not validating the textbox and no message is being shown. It seems that I gotto write the validation code explicitly in the toolstripbutton_click event which is too troublesome when there are multiple textboxes and toolstripbuttons on a single form. What I want to know is whether the textbox_validating can be fired while the toolstripbutton is clicked? Handling toolstrips is really a headache. I'm badly in need of it.
If I set a image from Resources, then I am able to see it in the design mode, but it is disappeared after I run it. It shows me just empty! What is the best way to set a image for ToolStripButton?
My ToolStripButtons look flat. They are highlighted when pressed, but they don't look like buttons do. I want them to look like they're not pressed in and then press in when click with the mouse. How can I get this effect?

I want to display a ContextMenu when a user clicks a ToolStripButton. I'm using the following code to do so, and it works great, but I want to prevent re-displaying the ContextMenu when the user clicks the ToolStripButton when the ContextMenu is already visible.
If Me.ToolFilter.Checked = False Then Me.ToolFilter.Checked = True Me.ContextFilter.Show(Me.ToolStandard, New Point(Me.ToolFilter.Bounds.X, Me.ToolFilter.Bounds.Bottom)) Me.ToolFilter.Checked = False End If

But condition activeChild Is Nothing is not working properly. And Status ToolStripButton stay in True value. How can I setting change status ToolStripButton after all MDI child is closed?
Is there any way to set an ToolStripButton as an CancelButton for the form.One way i know is of capturing the Esc Key and performing button click, is there an direct wasy to link the button as the CancelButton
I have an editable datagridview that's been databound with dataadapter and datatable, and a normal button on a form. When i edit the dgv's cells and click the save button it fires the datagridview_cellvalidating event and if the cell validation is correct it updates and saves the current record to the datasource. Also, before save it commits change in any cell under editing. But when I use a toolstripbutton to do the same work, though it saves the dgv records but doesn't update the current change i.e. it saves the old records that are being fetched when the dgv was populated first during form load. Also, clicking the toolstripbutton doesn't fire datagridview_cellvalidating, datagridview_rowvalidating etc events. What it seems to be is it's not committing the change in any cell under editing. [Code]
Why isn't it happening and how can I make it work? how can I fire datagridview_ cellvalidating, datagridview_rowvalidating and other events; and commit cell value change by clicking toolstripbutton.
I am overriding the OnRenderButtonBackground method in order to use custom colouring, but I want to know if the mouse is currently over the button. I tried to get the parent control (the toolstrip) and the parent form and add all the co-ordinates together but this is not correct:
I can't change the cursor when it's a ToolStripButton.click event.I got 2 buttons that call "Rechercher".
EDITED : Only the Button is working. It seems that the ToolStripButton cancel my cursor...

I have a favorites bar in my web browser and when I display them on a toolstrip as a toolstripbutton but the bookmarks are stored as a string collection in my.settings and It only displays the url of the bookmark (not the document title of the site)Is there a way to have a toolstripbutton that has the text of the Document Title of the url and the url as the tag of the toolstrip button?
I have three forms (form1-3). my startup form is form3. This form calls form1.show. then form1 does form1.visible=false and also calls form2.showat the end form1 shows again.
I have a general query that I need clarifying by some intelligent boffins such as yourselves. I have the following code in a function:[code]Obviously the Dispose method will never be called on the site object or the helper object. This may be a stupid question but can I get an explanation as to how these objects actually get disposed of in memory? Is it just by the fact that the enclosing method they were created in has been disposed of?![code]
I have a gridview where ALL cells have a value that is an image from the filesystem, but I need to access these files for a certain function and so I've been trying to create a method that disposes of all these images thereby freeing them up on the filesystem (was received permission denied errors). The following loop worked for the first row of images but I can't work out how to do it for all rows:
or Each c As DataGridViewImageColumn In dGV.Columns c.Image.Dispose() Next
Previous in my app, I've created dynamic controls and and named them blah0, blah1, blah2 etc. There will be a different amount created each time the user runs the app.I'm now trying to delete all of the controls but doing something very wrong. I've got the following
dim checkboxes = Controls.OfType(Of CheckBox).AsQueryable() dim sPrefix as string = "blah" for each checknum as checkbox in checkboxes
[code]....
When I execute the above, it only gets rid of every second control and I have no idea why. If I swap the dispose with a msgbox, the msgbox appears every time as I'd expect. It would seem that disposing of a checkbox seems to somehow requery the number available?
why upon exiting a form which has the following code i get an "Incorect syntax near the keyword 'FROM' " ? The form is supposed to be disposed , so why does any code gets 'executed' ?
