I dynamically add picture boxes to a vb.net form. However, when I add the new picture box, it is always under/below/behind the picture boxes that I previously created. Is it possible to change it so that the newly created picture box would always be in front of the others?

View 2 RepliesIve got a container with a bunch of child textboxes stacked using dock top. My code updates the textboxes and they vertically expand/contract etc. I'm thinking that my code might run faster if I turn off the layout refreshing until all the updates to the textboxes are done.
I'm getting confused with what I'm reading about suspend/resume layout - do I need to suspend for ALL the child controls, then go through them all at the end and Resume individually?

how do i change the layout of the web form to Grid Layout so that i can place my control anywhere and not follwing lines or cursor
View 1 RepliesSuppose that one has a panel an inside it there are many buttons with Dock=Top. The button would tend to be stacked on top of the panel. How can I get a reference for each button from top to bottom? The button would be created in a random order, so I don't think that using the index of each button in the Controls collection of the Panel would suffix.
View 4 RepliesThis is part of the last coding that codeorder helped me with. I didn't include this in the last post because I thought this was something that I was going to be able to do. Unfortunately, it is not working properly. In addition to the controls being removed, the control rows after the removed row should be changed so it's still in sequential order. Private Sub PictureBoxRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim RowRemove As String = CType(sender, PictureBox).Name.Replace("PictureBoxRemove", "")

View 6 RepliesMy form contains a datagrid and a checked listbox. The listbox is populated on the form_load event. There's a function called when the datagrid's SelectionChanged event is triggered that modifies the checkmarks in the listbox. It all works fine when I manually click on any item in the datagrid.
However, the very first time the form runs, the checkmarks are not affected, even though the first item in the datagrid appears selected. I discovered that this is because the actual listbox is not yet populated on the form at the time the very first SelectionChanged event is triggered. So when the function tries setting the checkboxes, it doesn't get anywhere, since it doesn't see any items in the listbox.
Somehow the datagrid is getting populated, even before the form_load event is triggered. I need the listbox to be populated before the datagrid is populated, but I have no idea how to control this.
I am working on an application that requires buttons and links to be added during run time, it's a bit like a flow chart. The buttons are used to display information similar to a multi line text box, but I also use the click, double click and mouse events for these buttons. The links are drawn as label controls. My problem is that I want to control the format order of these controls with the buttons always being on the top layer and the labels one layer back so that when labels are added they aways pass behind the buttons. If this was done at design time it is very easy to use the menu Format > Order to get overlapping controls displayed the way I want. But, the controls placed on the form at run time do not have a Format or Order property.
View 1 RepliesThe code generator creates code with references to a component I am using, before it's dependent components (datasets) are initalized. Although I can correct this by editing the form.designer.vb file, everytime I make a change on the form the code is re-generated in the wrong order. Where does VS2008 store information about the order of the components for code generation.

Let's say I've got a TableLayoutPanel with 50 cells in it. Inside each cell is a separate text label. If I want to change the color of each of those 50 labels at run-time to the same color, is there an efficient way to do it? (so that I don't have to write 50 lines of LabelX.ForeColor = X, etc).
Not that I would mind writing 50 lines of code for this, but I would like to figure out the most efficient way to do this sort of thing, for future reference.
Is there an "easy" way to change a control's ForeColor when it is diabled? Yes, I know that this goes against the Windows standard.
On our forms, we have buttons with a dark blue background and a white foreground (the design is dictated by marketing). When the buttons become disabled, the ForeColor goes to a dark color making the button unreadable.

I'm trying to change the look of some controls in VB.An example would be a button, I now have a stack of 4 images on top of eachother. By using the mouseover events and such, I get the same result as a normal button. However, I'd like to be able to insert those images into a normal button like thing.
I know it's possible to do this by creating a custom control, but that'd end up with the exact same code, just in a different file.
However, the real issue would be a dropdown box and slidebar. I'd like to get them to look nice with my theme. (Background, buttons, borders. Things like that..). I got absolutely no clue on how I should do that.
I know that there's a tool to create controls, but that's from scratch and I can't get a grip on it, at all.
What I am trying to do is have a Form which can dynamically change the controls which are on it and their properties; this allows my main GUI to be more fluid and not have tons of groups and controls on it which I must hide and show when needed. To make this as extensible and reusable as possible, however, I want all the control additions/subtractions/edits to occur through a separate DLL which I write. The problem is, I can't seem to instantiate any controls in the Class Library because I cannot import 'System.Windows' or any of its children ('Forms').
View 9 RepliesMy program has two lists, one a listbox and the other a listview viewed in details mode.
Both of them change heights (get taller) for no obvious reason. I am having to add a call to a method that resizes them to the end of every method, which is kind of absurd, I think. Also, when the window size is changed, these components change size, which means I have to keep track of that.
Edit: I had also thought of adding a timer to handle this.
I m implementing control based security in my application. where i m saving controlname (per form) in database, which are to be restricted. So far I have implemented the security and restricted control get disabled.
Now what i want to do is that i have to prevent that for those controls the "control.Enable" property should not change. how can i restrict that.
I have achieved the functionality by canceling enable=true property in "Invalidated" event of the control. but this is not some generic way. I have to map this event for all controls in all forms :(.
What i really want is that as all my froms are derived from same parent which implements the security. so the parent should some how restrict enable property from changing.
So,HOW CAN I PREVENT CONTROL enable property from changing in their parent class?
I have come across a problem with visual studio 2010 & vb.net. i have a few custom controls on the form and few standard controls. When i build the application, the custom controls automatically change size and location. Anchoring and Dock properties are fine. Anchored to Top Left without dockstyle. Even if i fix the location and size in design mode, after i run the application the controls again change back to weird position.

View 6 RepliesAll my forms inherits from one base form where we handle background paint and set standard properties. Recently, I think of cheching if the app is running on Vista or Later to use Segoe UI font, and I added this.

The controls and forms seems to be thinner (in width), so square picturebox became vertical rectangules!

View 10 Repliesfirst post here at the forums. I am a complete noob when it comes to VB .Net, but I have done a lot of VBA programming and some VB6 back in the day. I have posted this question on two other forums (including the MSDN forums) and no one has responded so please let me know if I need to clarify the question.
I am (trying) to write my first .net app which reads/writes data to a device connected over the serial port. I have manged to get it to work to send commands to the device and receive the reply back, mainly using the info from this article: Beth Massi - Sharing the goodness that is VB : Reading from a Serial Port and Saving to a Database
However, I am having problems with updating the controls on the main form based on the received data from the serial port. Basically I want the user to click a button (one of six on the form) which will send data to the device, then based on the response from the device, the BackColor of that particular button, will be changed accordingly. I just am missing something b/c the button click is a different sub than the sub that handles the form controls update and I can't get the two to talk
