View 2 RepliesI am programically creating a 2 buttons at runtime....I'm assigning the first button to open an image from file and display the image into the picture box. got that part.
The second button is where I am getting hung up. I want to assign the second button to delete the picture box from the form when I click on it but whenever I go to put in the code it throws an error at run time.
Anyone know of how I should code this to dispose of the picturebox when I click on my button?
It a snag and couldn't find anything on google pertaining to my situation so I figured asking here was better than searching for hours on end for something I may not even find.
I have a button on the main form which generates a new instance of the usercontrol in the flow layoutpanel of the currently selected tab of the tabcontrol.
Then I have a button in the user control meant to delete itself from the flowlayoutpanel.
I would like to use Graphics.FillRectangle or Graphics.Clear with semi-transparent colour (e.g. ARGB=128,0,0,0) to darken entire area of the Graphics object except some specified (rectangular) area:I know this can be achieved with four FillRectangle calls, but I wonder if it cannot be done easier.I am aware of simple clipping (Graphics.SetClip), but this allows me to clip everything outside the specified area and I would like to achieve the opposite.

View 4 RepliesHow can I control what is filled into the table adapter at runtime? Basically, I have a table full of thousands of rows, and I want to limit this to just 1 row. I want to specify an ID number and be able to pull up that row in the table, and I need to do this at run time. What are my options, and what is the easiest way? I want to make sure the data is still linked to the original row in my database, that way the changes are saved properly.
View 5 RepliesI created a custom control and add it to a form programatically.
The user can add and move them all over the form.
The problem is when I want to clear the form of my user control I don't know how.
I created an array of my control called ctlCorkNotes
Say I create ctlCorkNotes(1) and now I want to delete it.
How do I do this so it is gone and would have to recreate it to show up again?

View 1 RepliesGiven a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.
i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.
I think this would be something like >= the formula of the red line and >= the formula of the green line?
I'd like to implement this in VB.NET
When I've used the remove handler method in my code, I get this warning:The 'AddressOf' expression has no effect in this context because the method argument to 'AddressOf' requires a relaxed conversion to the delegate type of the event. Assign the 'AddressOf' expression to a variable, and use the variable to add or remove the method as the handler.Why do I have to assign the "AddressOf" expression to a variable?

View 1 RepliesWhat's the best way to dynamically remove method calls at runtime? Essentially what I'd like to do is pass a parameter to my application. Let's call the parameter level. Depending on the value of level, I'd like to essentially remove all the calls that have higher levels. I have the following but was wondering if there were a simpler/cleaner way to remove the calls:
Ideally I'd really like to write something like:
Log5("message")
And just have Log5 work or not call if it doesn't exist. My goal is to actually remove the call. The overhead for calling level 5 logs that test and return is fairly high and I rarely use it.
Module Module1
Delegate Sub Log(ByVal message As String)
Public Log1 As Log = Nothing
Public Log2 As Log = Nothing

I have a toolstriptextbox and a custom context menu strip with a "Cut" menu item. When you select text in the textbox, display the context menu and select the menu item, the cut method of the textbox is being executed, the text is pushed to the clipboard, but the text is not being removed from the textbox. The code is as simple as follows.
Sub menuItemCut_Click (byval sender as object, e as eventargs) handles menuItemCut.Click
textbox.Cut()
End Sub
I have verified the event is fired, and the selected text in textbox gets sent to the clipboard. For some reason the selected text is not removed from the textbox. Has anyone ran into this issue before when working with a toolstriptextbox?
