So I need my program that will read some cells on excel and then dynamically create textboxes on the form to hold the cell data. Everything goes along swimmingly, until vb refuses to create new textboxes saying "new cannot be used on an inteface." I figure this is something to do with the Microsoft.Office.Interop.Excel... So how can I dynamically create new textboxes now?
The relevant lines of code
Imports Microsoft.Office.Interop.Excel
Dim newqlabel As New TextBox
how can i automatically update my value when a user changs the combobox item. At the moment i have a button click when the user changes the combobox item and press the button the values get updated, everytime the combobox item get changed i have to repeat it click the button to update the value. I want something where automitically as soon as the combobox item selected the total value in the text box to change without clicking the button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If ComboBox1.SelectedItem = "Seafood" Then TextBox1.Text = 3.5 * ComboBox2.SelectedItem End If
I'm trying to update a text field... in this manner:The main form (where I have the design):
Code: Public Class Form1 Public Sub ChangeTextBox(ByVal vVal As String) TextBox1.Text = TextBox1.Text & vVal
[code].....
First I click on the button to open the port. Then I do this code so whenever I receive data from a serial port connection, "Hello" string is written in the text field.. I debugged it, made sure COM Port is open, and data seems to pass to the textbox.. because when I put my mouse over to display the values inside the textbox it shows that "Hello" is stored.. and I tried doing the textbox1.refresh() but still nothing happens.. the textbox remains empty!
what is the common interface between textblock and textbox when it comes to dela with text stuf?
What I want to do is to create a procedure that accept a textbox or a textblock and change fonts stuff is there a common interface for them that dela with font stuff??
my interface is like this, i've put 4 text boxes above, followed by a Generate Button in the middle and a multiline text box below the Generate button (please see the attachment)
so all i want is when i click the Generate Button, i want the data entered inside the above 4 text boxes to display in the multiline text box at the bottom in 4 seperate lines and not in 1 row. Also i would like to have some line spaces.
this is the code i used
Code: ' This is used to display in Bold OutputTextBox.Text = "" & TextBox1.Text & "" ' This is used to display TextBox2.Text
[Code]....
Just wondering, is it possible to put some tabs above the big multiline text box at the bottom, say like 4 tabs and each tab consists of a big multiline text box inside it. And then when clicked the Generate Button which displays different data ...
Is there a way to enter text in a text box programatically, without the "changed" event being fired? Or do I have to use a flag to indicate that nothing should be done when the text is changed by the program?
I'm working with adding some user-friendly options to a program that I've developed. A lot of these require handling painting the control myself. So far this hasn't been an issue except for this case.In a context menu, I have a text box that a user can type into. However, the context menu doesn't seem to let me input a label next to it so that the user knows what the text box is for. So, I wanted to paint the text box myself but I can't get the routine to work.I have tried to put the following code in the paint event for both the context menu and the text box itself. In the paint method for the context menu, the string and the text box show up at the top of the menu. Not 3 items down like it should. Also, I don't think the end result is truly a text box.[code]I believe that txtRect is set to the rectangle for the context menu and not for the text box itself. If you run this code, "Filter By:" should show up at the top of the context menu.
I'm running Windows 7 x 64 and the latest version of VS 2008.I have spent forever trying to get the following VB6 code snippet to work in a VB 2008 Windows Forms application. The VB6 application works like a charm, even on Win 7 x64.Here is the relevant (I hope) VB6 code. It allows me to select text in IE8's browser window and then drag and drop it onto a TextBox called txtLink in a very simple VB6 application.
Code: Private Sub txtLink_OLEDragDrop(Data As DataObject, Effect As Long, Button As Integer, Shift As Integer, X As Single, Y As Single)
I frequently use TextBoxes that expect date values. I do a tedious job every time to handle the Validating event. The Validation event ensures that the value is a valid date value according to the current thread's Calendar, and if so, formats the date to "dd-MM-yyyy".
I want a TextBox (e.g. DateTextBox) that automatically runs validation and formats its Text property. All I have to do is dropping it to the form.
I know I should use inheritance; but I do not know where to put the auto-validation code; and I do not know how to save the inherited class as a control in the ToolBox.
I have it so that for each entry node in the XML file, it creates a new label then it creates a textbox under it. Both are added to a Collection so I can reference and delete them later. The label and textbox are set inside a panel container. I'm planning to make changes to the interface.
I am in the making of creating a database desktop application using VB.NET. I want my UI to have similiarity the same as Microsoft Money. By this, now I want to make all my textbox to behave this way :
flat will have no border, or if it's still if the mouse hover on it, the border will get emphasized.That's all.I recognize that in TextButton, we have FlatAppearance, so we can tweak all Button to behave like this. But the same is not happened for TextField.
How can I get this interface programed into VB?Here's the interface:
USB data sent from the PC:
Byte 1: Scan Quiz, with value of 0x55 Byte 2: Number of bytes to receive, with value of 0x02. Byte 3: Mask, with value 0xFF to enable the first 8 quizzers. Byte 4: Mask, with value of 0xFE to enable the next 7 quizzers
I wish to have the main screen just like the Kaspersky main screen, in my applications. That is, I'm really impressed by those tabbed menus. I mean, the user will select the menu from left side and corresponding menus and details is shown in right (see the pic below). How can I do that ?
How do we automate the process of deriving an Interface from our already-designed class?In other words, I wrote in completion my entire class and now desire to automatically construct its interface. EG: Say my class's filename is "Car.vb", I now desire "ICar.vb" derived from the class "Car" that I've written.

I am working on a sports management game and have already received some terrific help here with some XNA stuff. I now need some help for the user interface though. This game is very menu-centric, with loads of stats and tables and such. It is therefore paramount to get it right!
So far I have been doing all of the work on my 24" monitor at 1920x1080. Whilst the form is 1920x1080, the menu fits within a 1280x1024 top left region of the form. When I run the game on my other computer, which has a 19" monitor at 1280x1024, I was expecting a large chunk of the form to be cut off but the menu to be all visible. Well, it is all visible but things screw up. Different controls will overlap and such. I'm using Krypton Components for most of the UI and some of the text boxes seem to shrink vertically so you can only see less than half of the text. I have no idea why, they won't all do it.
today I successfully configured an interface to work with a test database I created in MS Access 2003. The database consists of only 8 records with 10 fields.
I used the basic built-ins with VB 2010 to build the interface in a simple form which shows only 6 of the 10 fields. It all seems to work well, that is the connection string built correctly, and I can run the program and view the individual records. My trouble is that when it goes to the 1st record it's actually the 3rd record in the database. And when I go to the last record it's actually the 2nd record in the database and the next to the last record is actually the first record in the database.
why the program seems to start at the 3 record and shifts the first two records to the end. All the records show up, it's just that they are somewhat out of order.

I'm trying to hone up on my (beginner) coding skills & I would prefer that the the 'Designer coding window', not the 'Design window', wouldn't interfere with these studies. Sometimes it's there & sometimes it's not. I don't understand it at this point & would prefer it wasn't there. All I need is the 'Design window' & the 'regular coding window'.
In VS2008, I can stub out interface members with the following code using TextSelection to insert the implement line and then "simulate" the Enter key by inserting a new line. However, it doesn't work anymore in VS2010.
CodeClass cclass = {Target_Class}; TextSelection txtSel = {After_Class_Declaration_Line}; foreach (string i in interfacesFullName)
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.
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.

This is a followup to this thread, where I'm trying to draw two sets of dots using HatchBrushes to create VS2010-like interface. If you take a look at the zoomed image of the IDE background (blue with dark and light blue dots): that is what I'm trying to draw using GDI+. In the previous thread ForumAccount find the correct HashStyle to use (Percent20), but there is a problem: I need to draw two sets of these hatchstyles: once with a slightly darker color and once with a slightly lighter color, at an offset of one pixel downwards.
I was wondering if I could elicit some tips on how to procede with an interface design approach.That is. What is a good way to go about establishing a "work area" where one can have multiple "floating forms" in this area.Can you have a form which occupies the entire windows desk top and the other forms "float" in this space? the "floating" forms would need to interact with each other where pressing buttons etc on them would affect other forms on the "workspace") Or what would be a good way to start accomplishing that? Or is there a better way to get the same effect?
I'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)
.Dll: Code: Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer Function SetData(Data As Integer) end interface
[code]....
this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.
