Find Selected Words And Change Their Font Properties Without Modifying The Rest Of The Text
Apr 16, 2009i want to create a html editor. to get started, i want the app to be able to find certain words, and change the font/color/size/etc. as for <a href=""><b> and so on, without changing the rest of the text after the selected text was modified. i'm sure that it has something to do with RichTextBox1_TextChanged for text that is being typed and just a button click for modifying selected text.

View 11 RepliesVS 2010 Modifying A Collection Currently In Use On A Different Thread?
May 17, 2011So one of my programs logged an error the other day that I am trying to fix. The error was Collection was modified; enumeration operation may not execute.To overly simplify my code, users can add or delete objects from the collection at runtime. In the background, on a separate thread, a process runs every so many seconds that syncs the data in the collection with the data in a flat file.
To avoid my problem, it seems the most logical to create a COPY of the collection at the start of my second thread's procedure, and run off of that.How do I do that?If I try to say something like.

VS 2010 Modifying Balance In Access Database
Mar 24, 2011I'm building a money management type application for just overall practice with Visual Basic, and I'm having issues modifying a number.It's a checkbook ledger, which stores the information in the text boxes into an access database. When you first load the screen, it asks you for your account balance (still a work in progress) which puts that data into a label on the form. When you add a record to the database, that new amount will get added/subtracted to what you typed in for your account balance.The problem I'm running into is the save function will first check if a radio button is clicked or not and negate the amount depending if you click Credit or Debit. Then after that's done, it performs the Sum aggregate function on the Amount Column in my database which puts the number into a variable. That variable is then added to the account balance that you typed in.I'll supply two of the functions that this is regarding. The Balance() function runs when you first start the form, and the Save() function is where the math happens.The accountAmount variable is declared under Public Class so that way the save function can use the variable to do the math required.

VS 2010 Express - PictureBox Design Properties Box Shows Properties That Cannot Be Accessed?
Mar 5, 2012In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?
Reading And Modifying MP3 Audio-file Metadata With VB 2010?
Oct 8, 2010Does VB 2010 offer native support for reading and modifying ID3 metadata in MP3 files? A brief search through MSDN shows me nothing, and I see someone says he had to write his own library of code for it. But that was some years ago, when you had to write code to access JPEG Exif metadata, and I know that's changed with the Image class and the GetPropertyItem method; so I'm hoping MP3 files have their own methods and properties now for this.
View 4 RepliesPassing Data Between Forms Without Any Public Methods Or Properties On The Forms
Dec 28, 2009Passing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.
' File Definitions.vb
Public Delegate Sub MessageDelegate(ByVal sender As Object, ByVal e As MessageEventArgs)
Public Class MessageEventArgs : Inherits EventArgs
Public Message As String
[CODE]...
The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.

Forms :: Accessing MS/Word Document Properties?
Nov 1, 2011I am trying to access MS/Word document properties without opening the file in Word. Right now I have an app that reads the document properties but it has to open the document in word. This makes it run very slowly and also makes it susceptible to crashing if the document is corrupted. In Windows Explorer, you can right-click on a word document file and select properties. The ensuing dialog box contains, in addition to the usual information, two additional tabs labelled "Summary" and "Custom" that correspond to the same tabs in the dialog box you can open from File/Properties menu in Word. I know windows explorer is not opening the document in word because there is no instance of word.exe in task manager and because it has no difficulty in obtaining this information from the file even when it cannot be opened in Word because the document has become corrupted.If anyone could help me figure out how to read custom and built-in document fields (properties) from the file without opening it in Word,
View 1 RepliesForms :: Object Binding - Properties Didn't Set The Value?
Mar 17, 2011it's about object binding, yes it's just a simple binding. but i don't know why it won't work.for summary, i will write about what i am doing:
1. i have one solution, and have two project in it. WaitressDataWin and WaitressDataObject
2. inside WaitressDataWin, i have 'waitressdata.vb' . this is my simple form , there are some basic textbox (waitress name, address, phone)
3. inside WaitressDataObject, i have 'waitressDataObj.vb' is where i put my object class, i have WaitressName property, WaitressAddress, and Phone.one of my property is like this, others are same except the name of course.
Private _WaitressName As String
''' <summary>
''' Gets or sets the Waitress Name[code]....
4. i create data source , that is object data source. i add reference so i can add my second project which is WaitressDataObject and set the WaitressDataObj as the data source.now i have datasource with three properties (WaitressName, WaitressAddress, Phone)
5. I bind my textbox, by dragging the WaitressName (in datasource) to my waitressname textbox .. so on to all my properties.., i also get bindingsourcecomponent, WaitressDataObjectBindingSource
6. then I put this code to my form load :
dim wdm = new WaitressDataObj
Me.WaitressDataObjectBindingSource.DataSource = wdm
7. done, it should've been worked, but it didn't , i don't know why.. , every time i fill one of my textbox, the properties didn't set the value, i put breakpoint in the 'set' part of all my properties but it never breaks anyway.. (the 'get' part is good, it read my property value when i load the form). so i just had problem in my 'SET' Part.
8. I think i had checked on my variable (word, case sensitive,etc), no problem.

IDE :: Setting The Same Properties For All Forms In A Single Application
May 15, 2012Most of the apps I write have a base / home form and a few other forms (three of four typically) which pop up in response to controls clicked by the user. I'd like to be able to set some properties to be the same for all the forms in an app; particularly properties like BackColor and FormBorderStyle. Yes, I can manually set the individual properties for each form in the VB IDE, but I'd prefer to be able to have one line of code in the base / home form for each property along with one line for each dependent form which says something to the effect of "use the same property value as the base / home form has". Overall, my objective would be to have one single line of code in the app which, when changed, would apply the changed property to all the forms. For example, a single line which I can change to take the BackColor from Apple to Orange for all the forms ...

Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.

I can already get the screen information by creating a new instance of screen and reading the information such as index, bounds and everything else.I'm trying to create a virtual screen object to hold the information from the screen so I can work with it, or add other properties to it.[code]This all works perfectly how I want it to. Except I would like to do one more thing. How can I make it so that instead of getting Virtual_Screen.Top, I could get Virtual_Screen.Bounds.Top? That way I could create other properties such as Virtual_Screen.Border.Top..I have no idea how to code, or what that would be called. It's hard to search for something you don't know the name of.
