I finally figured out exactly what I do not understand in vb.net. What I am needing to know is how to associate one object to another such as how would I associate text box(A) with text box( so that text box ( gives me the correct output after I type input into text box (A).

I am making a program with tabs, and in each tab is a textbox for editing a file (like how VB's designer does). How can I match up a textbox with a tab so that the cut, copy, paste, select all, etc. in the menu can tell what textbox to preform actions on? I was thinking of getting the current selected tab, and somehow finding the textbox associated with that tab.

View 1 RepliesI am trying to find a way to associate a key with an index for a Listviewitem in VB.Net. I'm not even sure if it can be done with .Net but I know in VB6 I could do a
Listview.listitem.add "somestring", "somestring".
For the application I am using this in, I cannot have duplicate item.text so I would make the key the same as the string. this also made accessing the item easier since I didn't have to rely on index to update the subitems.
I am facing another issue. I want to associate a timer to my function. Actually what i am doing is that i am tryin to store certain values in a database. A function is such that it calculates 5 values and stores them in a database. While storing them in the database it displays them in a textbox on the form. Now i want to display them one by one which it does. But it does it so fast that i can only see the last value that it enters in the database inside the textbox.
Can i make it show all the values slowly one by one.
Private Sub dbInsert(ByVal strfile As String, ByVal hashoffile As String, ByVal p As Integer)

I have gotten my application to open with an associated file type, but now I'm trying to figure out how to associate the file types to the app. I associated them on my PC manually by right clicking on a file and selecting "Open With.." and check-marking "Always use this application to open this file type".What I want to do, is have my program make itself the default application for a file type with the press of a button.If it makes it easier, I'm writing a text editor and want to give the users the option of making it the default text editor for .txt &/or .rtf files.
View 1 RepliesHow would i do to get the regkey from my program and then register it into the windows key register so that users can select Open With... [MyApplication]?
And this brings me to another question, how can i get the data from a file if someone opens my program with a file (Open With...)? Or else maybe how can i get the path to the file which opened my program so that i can retrieve the data from the file?
In my VS-2008 (VB.Net) application, I am using a background worker to make my main form more responsive. In case of any error (in DoWork event) I m displaying the error on another form. In this case main form cant be a parent of error form so if main form is clicked, error form go in the background (behind main form). I want to restrict the user to interact with the main form while error form is appearing. Is there any way to associate these two forms such that error form always appear in front of main form.

View 2 RepliesI have problem to associate an Icon to the specific extention like *.nst which is my application's file.
I can associate icon by writing some registry entries where I have given the path of the icon file. but I don't want to do like this I actually want to embed the icon file into the EXE file and then set the ICON.
I have embeded the icons into EXE by doing some stuff but when I have given the icon index that icon is not associated with the file only first ICON is associated.
I am working on a project that we need to associate an image with a radio button. When the Radio button is selected the image show when its not the image doesnt show.
I am having a problem trying to get this work. I was told that we can use the radio buttons checked attribute and to set the flag but I cannot figure out how to do this.
I have this information but I do not understand what exactly it is referring to at this point:
When the program begins running, the focus goes to the control with the lowest tab index. Because that control is likely to be a radio button, one button will appear selected. You must either display the first flag to match the radio button or make the focus begin in a different control. You might consider beginning the focus on the button.
Set the Visible property of a control to the Checked property of the corresponding check box. That way, when the check box is selected, the control becomes visible.
Because all three selectable controls will be visible when the project begins, set the Checked property of the three check boxes to True at design time. Set the flag picture box to Visible = False so it wont appear at start up (if you plan to display the picture box at start up, its Visible property must be set to True.)

I'm doing a school project in VB 2008 and I'm trying to get the buttons on the form to activate when you hit a given key. Like if I hit the "1" key, either on the numberpad or the keyboard, the "1" button would activate. I've tried the KeyDown method without sucess, but that might just be my code...The teacher suggested I use a txtbox instead of a lable for a display and then just disable all but number keys (which I can do, but that creates other problems with the input). I just want to be able to hit a given key, and have it correspond to a specific button. [And I can't use the ampersand hotkey thing... it underlines the txt in the button and makes it look ugly and it doesn't work with special characters]

View 3 RepliesOn my datatable (I hope that's the correct word) I have two columns that I want to store color values. I changed the data type to "System.Drawing.Color".
However it would appear I cannot simply type in the string (e.g: "Color.Black") to add it to the database. And when using an update SQL query and make it look for color values on the form, it wants to convert them to string.
Is it possible to store color values like this in this way or do I have use another method?

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 have a winforms application that calls an command line program. My application is MyApp.exe for example, and the application I call is OtherApp. exe - if my user exits my application properly, I can "kill" the instance of OtherApp.exe - however if the user uses task manager to kill MyApp.exe, I cannot kill OtherApp.exe... when I load the OtherApp.exe, is there a way to associate it with MyApp.exe so MyApp.exe can kill both automatically? I only allow MyApp.exe to load one OtherApp.exe at a time, and it is stored in a global variable.Basically even if OtherApp.exe is currently running (inside procJob), I want the procJob (and associated OtherApp.exe) to be killed if MyApp.exe exits by force in task manager.[code]
