I am trying to locate text on a web page, and somehow high light it, put focus on it, or something.url..I have a web browser object, and I am loading am loading the text of the web page into a a string. I am able to search within that string to locate my text ok, but I'm not sure what to do next. As I stated, I am wanting to either highlight the text (which I think would involve re-rendering the web page) or perhaps automatically scrolling down the page to where the search hit was, or something.[code]
I just pulled an access dbs that contains obj fields into a VB project in a gridview in a windows form. when the form is called I get an error message on the gridview: System.arguementexception: parameter not valid.
I have no idea what is going on, but it is apparent that the OBJ field data is not carried over into the dataset. The data in the OBJ fields consist of shortcuts to applications.
I am using VB.NET 2010.I have a Queue to save different data (which all come from a class of mine) as FIFO Now, I want a Function to count the saved classes in my Queue, but this isn't working
My Code look like this
Private Function QueueSum(ByVal myQueue As

TryCast seems to be wrong. - because the Intelli Sense tells me, that "SATZ" isn't declared.
I have been getting some nullexceptions on the following lines of code...:

Its a text editor that i am working on. When a text is bolded and i have selected it, the button for bolding text becomes checked and same goes to the other ones like italic,underline and strikeout. but if I have selected a text with bold and italics and multiple ones, it gives me a "Object reference not set to an instance of an object." How could i solve this?
this is the second time I have had the same problem come up so maybe some of you have had the same issue. I have a form that has only a text box a list box and a button. The list box is loaded with part numbers from a database, the text box is used to search for a part number and the button is to accept the selected part and close the form.
I'm nearly finished building a Black Jack game for college I've just got one small problem that I need some help with. It's probably just something really basic that I'm missing, but I've not been using VB for a very long time.The problem is with counting up the results after each game. I can get the counter to work and displays the results in a text box like so...
Shell(Application.StartupPath & "myfile.txt", vbMaximized Focus)The code above shows the error that the file does not exist. But it exists. I tried the same code for an .exe file it works great.!
I'm familiar with Visual C# and the try/catch for that but I cannot seem to figure out how to do the same thing in VB. Basically I can't figure out how to get the try/catch to work with text boxes and input from the user and whatnot.I've tried setting the textbox.text property = "" but that has no use, I've been trying to find something on Google about it but I cannot seem to find a single thing about textbox try/catch statements. Is it possible to do it with text boxes?
I have made a text editing application and, as you might have guessed yourself, I needed to add save features. Well, what I have implemented so far is the ordinary "Save As..." feature which I made by using a common SaveFileDialog. Now it's time for the hard part. I need to add the "Save" function located in many Windows applications (Notepad etc.). This is what I'm working on at this moment but it doesn't seem to work.
I created a simple user control with a label, and one property that allows me to set its text.I can call the property Text2 and everything works well, but if I call it Text it doesn't work.
I tried both this: <Browsable(True)> Public Overrides Property Text As String
Couldn't think of a better title.(Background on the problem/me)Okay, so, first question/post here, so hi. Now that that's done with, the information pertinent to my problem. I'm fairly new to VB (and programming as well, aside from screwing around with C++ and learning assembler(well, attempting is the better word) god knows how many years ago), and have only seriously been programming for about under half a year, and my skill level is about at that stage. Only been using VB.Net, nothing older. Depending on the time of day and if I'm home or at school, I fluxuate between VB express and Vis Studio 08. Umm, this program I'm having trouble with was on a test that I took yesterday (took the problem home with me cause I really wanted to figure out what was wrong with it).
The stipulations of the test were: No For->Each Loops No using Built-In Sorting or Searching Functions
I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj Inherits baseObj Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
I found that when group by multiple values does not work well with VB.NET, but it works well with C# ,here are my code, is there something wrong with my VB.NET Code? Here is my VB.NET code:
I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
I have a form that works on my local Machine I created into. I have Office 2007 on this machine. I created the Form with the Excel 12 Reference. I move the Entire conetence of the Project folder to my work computer. Which has Office 2003. Do I need to recreate the form with the Excel 11 reference. I could not get the form to work on work computer. IT has a com error. I am acessing the EXE for the debug folder w/in the Bin Folder.
I am encountering an interesting problem regarding using Crystal Report 9 with VB.NET 2008. Being asked to create Crystal Report without using attached DataSet or Tables. Instead use TEXT OBJECTS to be filled with data using DATAREADER.
The coding below running well except that it does not create a new row resulting in all the rows from DATAREADER overrides the one before it. The DATAREADER has 15 rows but on the Crystal Report it only display the last row from DATAREADER because of override the row before it.[code]...
I read from a text file to see what I need to add to my MenuStrip. Each line in the text file is a new item. When I read I add the new item's OnClick event using AddHandler to get its text when it's clicked. Here are my two subs[code]....
I need to write a procedure which will allow me to set readonly attributes for certain objects, for example:My form contains two text boxes box1, box2.My sub procecdure will contain code which sets box1.readonly() = true, but i dont want to name the "box1" in the sub procedure but pass it as a parameter....I thought this could be achieved using :
private sub disableobject(byval inobject as system.object) inobject.readonly() = true end sub
If I pass Label1.Text through a function it treats it as an object and not a string. Which is good.
But when I do something like:
Dim temp As Object = Label1.Text
And then pass it through a function it treats it as a string, which is to be expected. How can I make it so I can set Label1.Text to an object the same way it would if I just passed it through a function.
Edit: Here is specifically what I want to do
Public Sub test() setIt(Label1.Text, "Test") 'this works Dim temp As Object = Label1.Text
I am trying to load the text file to the ListBox Object. But it doesn't work.
' Initialize an instance of the StreamReader object and declare variables Dim objReader As IO.StreamReader Dim intCount As Integer = 0 Dim intFill As Integer
I want to modify the default Object text size for all objects I place on my form. When I am teaching, it is hard to see the text on the objects. I have changed the code area to 16 pt, but I have not seen how to modify the default font size of the object. They all are 8.8 pt.
