Upgrading Software Written In VB To Include More Graphics/controls/indicator For User Interface?
Feb 18, 2011
I have been given a project to update software written in Visual Basic. The software and some files are enclosed in a folder and was written 3 years ago. I have no clue what to do. All I have been asked to include more controls. The user interface allows user to select three processes by clicking on the buttons on user interface. The new requirements is to add two more buttons. There is not much information so I have to use only the resources available. When I tried to open the project, visual studio prompted to convert the project so its compatible with current version. I could open the project but dont know what to do from there. Please guide me towards the right direction. If the project folder is required please advise me how to attach it too.

I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.

I have inserted a form into my project that a friend sent over. The form works but if I add more controls to it they are not displaying.
The controls are all there in the <form>.designer.vb file but are simply not displaying when I run the form.
I have looked around the net but can find no reference to a similiar problem.

I'm having some problems with custom controls and anchors today. I made a custom control containing a picture box and a vertical scroll bar. When I adjust the form the custom control outer area (the blank part) will adjust to the size of the form but the picture box and scroll bar do not. I have the picture box anchored to all sides and the vertical scroll bar anchored to the right side. They just will not adjust with the control when it is resized on the form.

I have a project running in my old computer. It has panels,textboxes,labels etc. It occupies the full screen when running.I bought a new computer with a widescreen format. When I run this project it only occupies 2/3 of the screen.
What properties of the controls must I use so that I can run this program in any size computer and still occupy the full screen i.e the size is proportionately resized depending on screen size.

I'm to .NET and all the associated cool stuff you can do, but am wondering about efficiency with User Controls and JS includes.
My user controls are mainly made up with an ascx display page and .vb.ascx code behind, as is customary with the code-behind coding style of .NET, which is great for coding simplicity although it does double then bear of files required. However, as I understand it, the server compiles these and returns the HTML efficiently.
Where the Control requires JavaScript, as I'm developing, I am making external JS files for each User Control with the same name, so the user controls consist of 'controlName.ascx, controlName.vb.ascx, controlName.js'
If a page requested by the user contains several User Controls the browser will be requesting multiple JS files, probably a master page JS file, jQuery AND each required file for the respective Controls.
This approach makes sense to me whilst developing and as everything's all kept nice and neat, making problem solving easy, but when it goes live there'll be loads of get requests from the browser, given that each time the browser gets a file, even the process of requesting the file to check if its cached or not must take some time.
Would I be best off including my JS inline in the ascx files, or code behind, directly inserting the script, or what is the 'correct' way to handle these multiple files to reduce get requests from the browser.
I'm using CSS sprites for buttons and stuff for the same reason, so wondering what to do with JS files. In my case CSS is generally handled by classes in the primary pages, so these are not an issue.

I don't know the best way to use multiple forms in VB, but I have created a problem and I'm not sure where it came from or how to fix it.
Background: I start the program at Sub Main. This is the main function:
Code:
Module modFunctions
Dim frmD As frmDAQ
Dim frmT As frmTrendView
[Code].....
it works, but I don't want to have to change the entire project.

The project I'm working on (the same one I'm always asking about) has tabs as the main navigation. I've made some User Controls to sit above the tabs in an attempt to reduce the number of overall controls that are being used (to great success). Now, however, there's one control that overlaps some controls on a tab that are obscured by my newest UControl and I want to make the background transparent.I've seen that AtmaWeapon keeps pointing people to this page detailing how to make the background transparent. That's great and it worked for me. All I did was create the
Code:Protected Overrides ReadOnly Property CreateParams() AsSystem.Windows.Forms.CreateParamsand it worked the way I wanted. Yay. I did write the rest of it too as well as part from a post I saw on the msdn forums, but they weren't needed to get the effect I wanted.However, I've got a number of PictureBoxes on this UControl that should have a BorderStyle of "Fixed3D". However, when this UControl is repainted the borderstyle doesn't reflect this (Note to self: don't .Refresh() a control inside its own .Paint() event ). This doesn't happen the FIRST time they become visible, but only when they've shown up and are made to redraw (like toggling visibility). If the border changes programmatically they look fine

I'm trying to figure out how to make dragable controls like the ones in paint.net. see the attachment. they look like forms kind of because they have the red x at the top like a form does, but it kind of looks like a custom control too. Is it possible to make these types of controls in VB.Net 2008.

I have a form containing two panels. In both panels there are two labels and textboxes. I set the 'Center In Form' property of the labels and textboxes to 'Horizontally' and 'Vertically' in design time respectively. But as the form is resizable, when the size of the form is increased or decreased at runtime the controls are no longer center aligned in the panels. How can I handle this problem (provided th

If I have a control, in this case a button, can I restrict the area it considers valid for text?
In the attached image, the left and right arrows are custom drawn in the paint even, I also have a scroll timer that scrolls the text if the length exceeds the buttons width as measured by Graphics.MeasureString.
I want to restrict the text from red line to red line so when the text scrolls it does not interfere with the arrow indicators, can the text area be overridden to some custom region?

There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

I am using Visual Web Developer 2008 Express and making a Webform. I want to arrange my labels and drop down listboxes in a table to keep them together on the form in a neatly manner. If I use the 'ToolBox' on the side and drag a HTML table to the workspace I get a nicely formatted table with 3 rows and 3 columns. And I can drag and drop my labels/listboxes into these columns and all is fine and good.
If I use the 'ToolBox' and drag a ASP.Net table to the workspace it starts as just a boarder with '###' inside of it, which I cannot drap and drop controls into. I'm not sure how to place controls into it. I figured out that you can add the Rows - then Columns in the properties window, but that just adds more cells which have the '###' in them. I can make it work with the HTML table, but I just want to know if I can do the same with the ASP.net table.

I have a Main form that has a split container in it. In Panel1 there is a treeview control. Panel2 is initally blank when Main loads. Upon clicking on one of the nodes in the treeview a form will load in panel2 and adjust the location of the controls based on the size of panel2. The controls are all in a panel themselves so that I am only moving a single object.
Moving the controls when the form in panel2 initially loads works great. But if the size of the Main for changes then the only way to get the controls to reposition is to click on the treeview and reload the form in panel 2.Code for the tree.
Code:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Me.SplitContainer1.Panel2.Controls.Clear()
[code]....
I tried to with code in the panel2_resize bit i got an error as soon as I clicked on the treeview as i did not know which form was currently loaded. What would be a method to accomplish repositioning the controls in panel2 regardless of which form is loaded?

we all know how to dock or anchor controls so that they resize themselves accordingly when a form is resized. It works fine till we have rows of controls on left and right size of the form. But what if have three columns (Columns as in visual sense. I'm not talking about any column control containing other controls) of controls? For example a form having a bunch of controls in the left side, a bunch in the middle and a bunch in the right. There may be a few more bunches in the middle. Now while resizing the form, I want the controls to resize accordingly as well as change their positions to make space for the previous bunch of controls that are resizing.I mean, while the user increases the form size horizontally, the controls of the second bunch should resize and at the same time they should move right because the controls of the first bunch are increasing horizontally too. When the user decreases the form size horizontally the same thing should occur in the reverse order.I can manage it somehow using nested splitcontainers but that's too cumbersome. I would like to know if there's some better way to achieve it, like setting some property etc.?

I am attempting to write a simple 11ball style game. It requires images of poolballs overlapping each other. Since the balls will need some internal intelligence I was hoping to create them as usercontrols.I am having trouble gettiing the control's background to be transparent.Setting the background color to (Web) transparent only makes the background clone the form background color.

I am developing an app that has a treeview on the left in panel1 of a split container. When you click in a node it loads a user control into a tabcontrol that is in panel2. Some of the user contols contain webbrowsers that autorefresh every 15 sec (not under my control). I can successfully remove a tab by a contextmenu but I can still hear the clicking sound of the webbrowsers refreshing. Not sure what to do to completely remove the usercontrol. Treeview control code for one node: there rest are basically the same
Code:
Dim tabcount As Integer
tabcount = TabControlMain.TabCount
[CODE]...
Code to remove a tab and all tabs:
Code:
Private Sub RemoveToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RemoveToolStripMenuItem.Click
TabControlMain.Controls.Remove(TabControlMain.SelectedTab)
[CODE]...
I also originally had this setup to work without the tabcontrol and just load the usercontrol into panel2 of the split container. Each time a new node was selected from the treeview I would have SplitContainer1.Panel2.Controls.Clear() to remove the current usercontrol. I would still hear the clicking of the old usercontrol.

I believe that this is in the correct forum due to it being about creating an interface item, but if I am wrong then let me know and I'll try and bring this thread to the attention of the mods to be moved to a more appropriate forum. I am currently trying to create a generic navigation control with a similar style to the outlook navigation bar. I have figured out how I would be able to dynamically create the bottom part where you select the menu option, but I'm struggling to figure out how I would be able to create the top part, which can contain any user control that the developer would want.
So basically what I'm trying to figure out is, is there a way to allow for a developer to add controls to a specific area of your user control?If there is a way of achieving that then if anyone knows how to do this;In ASP.Net you have the login controls and with one of them, you are able to have different views depending on whether the user who is viewing the web page is logged in or not. Is there a way of achieving this in VB.Net for a user control that could be set up so that I could have the developer able to switch the view in the designer to show them the view for when a specific navigation option has been selected.
The one thing that I have thought of that could possibly cause a problem is having the capability of knowing when one of the user controls has been clicked, while I haven't figured this out exactly, I believe I should be able to achieve this by having an event for the navigation user control that provides the developer a reference to the control.
While I would hope that I have explained what I'm thinking well, its before my first coffee of the morning so I might have missed out some detail which would help someone to help me if I have then please let me know and I'll provide any details required.Also if what I'm envisioning is Pie in the sky, then let me know and I'll just have to make a base which I would just have to make a more bespoke system.

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.
