Making Dir Vairable And Adding Browse Function?
Jan 7, 2009
i have search for tutorials but none seems to work for me.This is my app code Public Class Form1 Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
[Code]...
As you see, "button2" renames files to backup, and "button3" renames them back to original name.How can i make dir (C:Program FilesRockstar GamesGTA San Andreas) a variable?And maybe when app starts it lets user to select their program path (browse function) then it will but their selected path to variable, and i can use this variable in my code as path?

I have a field in my db that stores the path to a picture that will be printed on the report C:Picturespic1.jpg). When I add the field to a input form, I want to allow the user to hit a browse button to select the path and picture name and then store that selection in the field. How do I set up the field on the form so they can do this? I am using VS2008.

I need to execute a stored function in oracle or sql through vb.net. I created a command object. Depending on the database type(oracle or SQL) i am preparing the Command text as Select functionName(?,?,?,?,?,?,?,?) from dual; (For Oracle) Adding the parameter values of the function. Now performing the ExecuteScalar which is not working saying invalid parameter. This works with ODBC connection string. But ODBC doesn't with 64bit. My Requirement: Code should execute a user defined stored procedure by taking the values at runtime.

I'm making an WPF-application that has a databound ListView. When loading the application, the width of the ListViewColumns will auto-resize, but when adding or changing an item it doesn't auto-resize. I've tried refreshing the listview, setting the width of the column to auto, -1 or -2 in both xaml and VB-code and I've tries changing the itemssource to nothing before refilling it with items.
This is the xaml code:
<ListView x:Name="lsvPersons" Margin="5,5,5,35" ItemsSource="{Binding Persons}">
<ListView.View><GridView>
<GridViewColumn DisplayMemberBinding="{Binding Name}" Header="Name"/>
<GridViewColumn DisplayMemberBinding="{Binding Gender}" Header="Gender"/>
<GridViewColumn DisplayMemberBinding="{Binding Age}" Header="Age"/>
[Code] .....
After pressing the button, a window will open to add a person. After the window is closed, the item is added to the listview with following code, which refreshes the items in the listview:
lsvPersons.ItemsSource = Person.getPersons()
So, what do I need to do to auto-resize the columns of the listview when an item is added or edited?

I am having trouble making a function that reorders the text put into a textbox. I then have to get that reordered data and put it into a list box.
Basically, 2 words separated by a comma are entered into a text box (say Wash, Car is put into the text box), then I need to get a function that reorders that string and be able to put in into a listbox that shows Car Wash. So it gets the word after the comma first, then gets the word before the comma. It should do this with every string.
Need to use a function for this.
Right now I really just have
Dim Word As String
Word = textbox1.text
'Then the function to reorder the name and return the reordered name will go right here
What this is suppose to do?
- Example, some puts Wash, Car into textbox 1. List Box 1 will display Wash Car.
- Basic, Visual in textbox1, list box 1 will display Visual basic

I'm sort of repeating the same steps. There's got to be a way to shorten it.I was able to shorten it before by making a generic function to create the radio buttons.This is the before the rewrite
Public Sub LoadPanels(ByVal tblClient As DataTable)
Dim count As Integer = 20
Dim tooltip As New ToolTip
Dim countName As Integer = 0

Is it possible to make your own function for a String? So you could do this:
Dim String a = "C:Windows"

I am writing a chat program and im adding a transfer file function but Ive hit i bit of a snag..The way my program knows its a file coming and not a regular text message is i added a 3-6 bytes prefix depending on what is being sent.
[Code]...
Ive tried the copyto method but since my file byte array is empty it throws an exception. If i wasn't clear with something let me know and i will try to explain better.

In the software I am developing for my A-level computing coursework I want to add a function to export the database (to backup, use in other computers, etc) and later on a function to import databases (that I had previously exported using this function). At the moment I have a SaveFileDialog, and I have filtered .mdb files only (as this is the type of files supported by my application). But How do I select what is going to be saved? (How do I point to the .mdb file that is located in the program's directory?)

I have an XML file and I have a function to which this XML is passed as string. I have loaded this string in Xmldocument and I need to insert few children nodes under one node. This function returns the modified XML string. I want that whenever this function is called, new child nodes are added, currently, It adds child nodes once.Do I need to overwrite the XML file ? If so, How can I replace the node with new node ( with new child nodes added) so that It has child nodes added before the function is called again ?
My code looks something like this:
Dim doc As New XmlDocument
doc.LoadXml(applicationXml)
Dim parentNode As XmlNode = doc.GetElementsByTagName("prList").Item(0)

I have a function that converts a .csv file to a datatable. One of the columns I am converting is is a field of names that have a comma in them i.e. "Doe, John" when converting the function treats this as 2 seperate fields because of the comma. I need the datatable to hold this as one field Doe, John in the datatable.

In the exam paper, student have to check the checkboxes [usercontrol does not work] whether the question is correct or wrong.Now as I have hundreds of questions, I cannot write the same code again and again with the IF conditions, is there anyway to make it a function or something then call it whenever is needed.As well as I wanted the marks to be added when a student submits the paper.

I am looping through all folders on the computer in a background worker. Starting with just the C: drive, the function works perfectly I've been tasked with adding recursiveness to this function to loop through all subfolders within each and every folder.
This is the working code without recursive. Startpath is set = "c:".
Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
Dim fs As New FileSystemObject
Dim fsfolder As Folder
Dim subfolder As Folder
[Code]...
EDIT: I was doing some testing and threw in an if check to skip the C:$ folders. Working ok so far and noticed something really strange. It doesn't loop through all the folders in the C: drive. I think it will loop through only the first 2 folders. One is C:Boot so I skip that and the other is C:Dev-cpp. It won't loop through the Program Files, Program Files (x86), or Users.

I am pulling information out of my Access Database and reading to a webpage. I need to add a update, delete, and email function to this page. I am trying to do this with the selection of a check box and buttons for each one. But I am unable to get the delete to do anything but redirect back to the orignal page. For the update I want to be able to pull the info in text boxes and just change the info and click update and it gets changed. I also want to be able to pull their email from the database and put it into a text box to be able to email right from the page. Code for show page and delete page below.

I'm a huge music person (got my own lil record thing going) but I'm wanting to design a program that would make music in my way. I have a decent amount of background knowlege of Visual Basic and Java I'm just wondering how could I execute this whole project. The Project is making a MPC Sampler. MPC is a drum machine; a machine with buttons that once you press it that it will play a sound from a drum (ex: snare, kick, tom, ect.) . So I would want to make some pads on my program that each have their own sound. Total of 16 pads. Which the design wouldn't be hard to make nor would the functionality of it having the play back sound (in my opinoin it wouldn't be hard atleast). But the thing is I wanna map out these pads to number keys on the number pad or keyboard. I'm not so sure how to do that. But that's all the easy stuff...
Also finding information is making a sound directory. What I mean by this is that I want to make a User Interface that will open up a file directory of sounds and the user can select what "kick" or "snare" sound he may want for the kick or snare pad. I don't know how to do that or even know what to search; neverless I don't know if this whole project idea is a good idea for Visual Basic or another programing language.
Also LATER ON I am wanting to add a record and export function that alows users to..well...record and export their beat or instrumental ha. That doesn't seem too too complex (mainly due to the fact that all it needs to do is record the users key strokes and then show them and play the sounds, but obviously it would get more complex than that.)
Here is an image of one of many MPCs but one with a directory - [URL]

I'm trying to write a 'developer friendly' wrapper for the Windows API EnumWindows - the problem is that the API uses a callback function that gets invoked on another thread, where as I want my wrapper function to simplify this and make it more useful by working like any other normal synchronous function and just returning a value.
Now if the API just called the callback once that would be fine, as I would just call the API and make the wrapper function wait until it got a signal from the callback function telling it to continue... but the API calls the callback function over 100 times (once for every window handle that exists). The biggest problem is that there is nothing that indicates that any particular call to this callback function is the last one, so my wrapper function has no idea when it is safe to continue and return the list of window handles to the caller.
The only solution I could think of is to do this:
1. The wrapper function calls the API and starts a timer that waits 2 seconds before it raises the Elapsed event. The wrapper function then pauses until it receives a signal (ManualResetEvent)
2. Each time the callback function is raised by the API on a different thread, it stops the timer (so this is before the 2 seconds have elapsed), adds the current window handle that was passed in by the API to the list of handles, then starts the timer again.
3. If the timer reaches its 2 second interval then it is assumed that we are at the end of the windows because otherwise the callback would have stopped the timer. So the timer's Elapsed event handler is what signals the original thread (that the wrapper function is executing on) to continue as we now have a complete list of windows to return.
This works fine and does exactly what I want... but I dont like it.
I dont like forcing the caller to wait an extra 2 seconds after the API has done its last callback but more importantly I dont like assuming that the API will never take longer than 2 seconds between callbacks. In reality on my PC it is never anywhere near that long between callbacks, it is something like 200 miliseconds, but I have no idea how long it would be on a slower PC and I want this to be completely reliable.
