[url] How is this done? Is it a control of that form? Or is it a splashscreen or something like that?. I've tried by doing that with another form instead, but the first form will get unfocused, and i want the main form to be always focused.
View 6 RepliesI am making a user control named MultiSelect, which consists of a textbox. In this textbox I put substring. I want the user control to show a treeview outside the MultiSelect boundaries where items matching the substring will be shown.
For me its no problem to make a treeview inside the MultiSelect boundaries but I need to save space on the original form where a MultiSelect control will appear, so I need to do it like the treeview will appear and after I choose items, it will disappear
Today I started a little sub that would let me move a control around the form using ssigned keys but would stop at the edges of the form. I can get it to move around alright but I can't get it to stop at the edges of the form.

View 1 Repliesi am trying to make a game in vb.net and so far have managed to create a sprite which is animated on key event. the only problem is it able to walk off the form out of site. i want to be able to create some sort of boundary so that when sprite position equals greater or smaller then the form width it can no longer walk in that direction, the same goes for the hight. i have tryed this myself like this

I'm using KeyDown to get the picturebox to move around, but I don't know how to keep the boat within the boundaries of the form. So if it hits the side of the form, I want it to just stop.
What control/procedure should I use to do this?
So I've created a series of objects that interact with a piece of hardware over a serial port. There is a thread running monitoring the serial port, and if the state of the hardware changes it updates properties in my objects. I'm using observable collections, and INotifyPropertyChanged.
I've built a UI in WPF and it works great, showing me real time updating when the hardware changes and allows me to send changes to the hardware as well by changing these properties using bindings.
What I'm hoping is that I can run the UI on a different machine than what the hardware is hooked up to without a lot of wiring up of events. Possibly even allow multiple UI's to connect to the same service and interact with this hardware.
So far I understand I'm going to need to create a WCF service. I'm trying to figure out if I'll be able to pass a reference to an object created at the service to the client leaving events intact. So that the UI will really just be bound to a remote object.
Am I moving the right direction with WCF?
Also I see tons of examples for WCF in C#, are there any good practical use examples in VB that might be along the lines of what I'm trying to do?
is it possible to draw an accurate circle in vb.net with mouseDown and mouseUp boundaries? I only manage to create circle-settings with rectangular boundaries using DrawEllipse. I've tried to work around it using pythagoras but it just doesn't work and I'm pretty sure I've got my maths right...
Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?
i've drawn two boxes (one with spotcolour color of orange) in a picture box. box a stays fixed at the bottom and box b can move. i've restricted box not move outside the picbox, but it needs to change color (to red) when it touches the picbox, and i've tried can't seem to do it. boxb also can't overlap boxa.

I wrote a simple application to help me with my work the interface looks like this:i use a button to add a new custom control every time by the following code :
Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim NewGard As New GardControl
NewGard.Left = x
NewGard.Top = y

but after the form's lower end is reached, the added controls appear like this:spaced greatly & exponentially from each other despite the y coordinate is accurately increased every time by 41?
Does anyone know how i would go about adding a control (a button) to the windows title bar area?Sort of like firefox does.

I have a form with four chart controls on it and i would like to count them at runtime but i'm hitting a snag.

End If

the count is returning zero when it should be returning 4 - what am i missing?
I've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?
I have a form that I want to have a control box so you can close it at any time but I don't want it to be movable from its origainal position. It opens maximized and I want it to stay maximized. I've tried all the different FromBorderStyle options in properties and I've tried all the SizeGripStyle properties though I can't say I've tried all the combinations possible between those two but whatever I've tried I can always click on the border at the top and then the form breaks free from its starting position and when it does the vertical scroll bar disappears.
How can I have this form stay in place with the vertical scroll bar and the control box and not break free from its starting position if someone clicks on the border at the top? If I try FromBorderStyle None then I don't have control box to close it. I was looking at the form events list and I noticed when I break the form free by clicking on the border that that is a ClientSizeChanged event.
After getting the current mdi active child form, how can I get it's control collection so I can access their data?

I have used '/resetsettings' already, and other answers to similar questions do not solve my problem. I have reinstalled, gone through every menu I can find (though I may have missed something)I don't want to type those event handler subroutines every time!
I read the boundary thread and I think im still lost on how to do this but my goal is to set boundaries so the snake doesnt just keep going off the screen, also how to set a boundary up so the snake cannot hit itself (like in the original snake game)

I have created simple windows form control with some events.
This form has button which opens Form with some settings.
Now, I need to raise the events inside the control when I click some buttons within the settings form ..
The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

I am still messing around with Cntrl/Copy and Paste from a menustrip. Paste is working fine. The copy is working to a certain extent. It will copy the complete text field from one control to another. how do I determine what is the selected text only. My code below:

View 12 RepliesI've got a Panel on a main Form containing a PictureBox control on Top of a TableLayout control. Both the child controls have their docking properties set to Top. The Picture control has sizemode set to Zoom.
What I'm finding is that the picture doesn't size properly when I start the app. There is a border at the top and bottom in the PictureBox control. It's only when I resize the overall form that it's correct.
So at the moment I've got this ugly bit of startup code, just to fix the problem Me.WindowState = FormWindowState.Normal Me.WindowState = FormWindowState.Maximized
