When changing properties of a ToolStripMenuItem at run-time, the changes are not reflected visually. If I check the values of the property that was changed, it shows the new value, but it will not show on screen. I have tried changing the Text value and it doesn't show the new text. I have changed the Checked value but it doesn't show as checked. I have even added event handlers, but they do not trigger.
View 3 RepliesI am wanting to be able to check to see if two images appear to be the same, within a certain threshold.These two images are the same to the eye, but one has slightly different colors. I have tried the following example:

Unfortunately, it only seems to detect when the images are identical. How can I determine if the images are the same within a certain threshold, with VB.NET?

I have been asked to remove or disable the close button from our VB .NET 2005 MDI application. There are no native properties on a form that allow you to grey out the close button so the user cannot close it, and I do not remember seeing anything in the form class that will allow me to do this.
Is there perhaps an API call or some magical property to set or function to call in .NET 2005 or later to do this?

How can I do a click event for all toolstripmenuitems, I can get it working for the menustrip:

End Sub
but I am stuck with the toolstripmenuitem.
I have recently moved from developing in vb.NET 2008 to vb.NET 2010. There is a form in the application that uses an old Ascend Gradient Caption control to visually separate sections of the form. These controls are located on a tab control. The problem isthat the gradient captions seem to be unstable. They appear in odd locations on the tab pages at runtime, and I can't seem to select them in the designer. I can choose them from the combo box on the property page and edit the properties, but they stillbehave erratically. I understand that these are older controls and was wondering if anyone has had this problem and/or could recommend an alternative control
View 1 RepliesI'm trying to use a split button from a tool strip to add and remove selected items in a listview.Users click the button to add the selected item which appears in the split button drop down menu as checked.The drop down menu has three items at any one time, each with a default value of <none> - this is replaced with the text from the listview when an item is added.When users click the item from the drop down, the item is unchecked and the text returns to <none>.
The drop down should populate from the top down so if a user removes item 1 or 2, the items below would appear to be moved up with the 3rd item now showing <none>.

I'm making a program that uses recursion to transform the nodes in a treeview to the items in a contextmenustrip. The nodes will have tags within them that when I add a handler to the menuitem, it will run through a script from the tag to tell the program what to do, the only problem is that I don't need a tag or an even handler for any of the menuitems that have dropdown items. How could I do this?
View 3 RepliesI am trying to create a ContextMenuStrip where I add a certain amount of ToolStripMenuItems based on how many columns are in a DataGridView via code. I am wondering, since I am creating all these ToolStripMenuItems in code, how would I handle the "CheckStateChanged" event on all of them separately? Or how can I figure out which one of those ToolStripMenuItems was clicked?
Here's a code example of what I mean:
Private Sub CreateCMS()

I'm writing a program for my algebra students to practice integers.Stuff like....

etc.
I want to show an explanation and for the addition and subtraction, I want to show it on a number line. For example, if the problem is 3 - 7, the number line should show and arrow to that goes right to 3, and then left 7 units (starting from 3). Then the student can see that the answer is -4.I could probably do this with some string manipulation, but what would be the easiest way to do it in a picture format? Maybe a bitmap.

As a continuation of my previous posting, which we were able to resolve, I am running into the same problem again, due to being unable to use frmForm1.Show().In my last situation I had to use frmForm1.ShowDialog(), which worked in that case, as it called another form, for example frmForm2.However, now I have a program that is sometimes required to recal frmForm1, and I get the following message: �Close the form before calling ShowDialog.But, in frmForm1,I include, Me.Hide() and Me.Close(). Also, before recalling frmForm1, from a procedure under Main(), I have added the following
frmForm1.Close()
To me that would suggest the form is closed, dead and buried, but the programme still stops at the point of:
frmForm1.ShowDialog()
With the same message: �Close the form before calling ShowDialog.
This is very, very simple question, I even posted on another forum, but apparently I didn't get the right answer.
