View 2 Repliesplaying an audio file that has been selected by the user.
The program I'm working on is an alarm clock, so that may give you an idea of the problem. Basically, I just want the user to be able to select his/her own song to play when the time comes. So, the user clicks on a button, and an OpenFileDialog pops up. The user selects an audio file, and then that file is going to be the file that is played when the alarm goes off.
I'm not near my Microsoft Visual Studio at the moment, so I didn't have time to test it, but here is a code that I think may work:
Private Sub btnChoose_Click
OFile.ShowDialog()
If OFile.DialogResult = DialogResult.OK Then

I am working on a project which use files with a .HRZ extension. These are image files with a simple red, green, blue, red, green, blue structure. There is no header of any kind. I know how to display these files in a picturebox or convert them to a bitmap, but of course Windows 7 does NOT know what they are, so just shows a blank icon in the OpenFileDialog. How easy would it be for me to add support for this file format to Windows and/or the OpenFileDialog so I can show a thumbnail of each file? I can create my own file browser but I would really like to use the OpenFileDialog if at all possible.
View 3 RepliesI have a 4 pictureboxes for a database I made but having a problem with loading images in to the picturebox. On my form I have a picturebox, 1 button, 1 textbox, and 1 openfiledialog.
My button click event code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
OpenFileDialog1.ShowDialog()
TextBox1.Text = OpenFileDialog1.FileName
Pic1PictureBox.Image = Image.FromFile(TextBox1.Text)
End Sub
I can add pics but if I don't select any image (just close the dialogbox) I get an error and not sure what to do ..or what to add. Is there any code to tell it to just close..
I try to view a datagrid with one empty row in it when the form loads. The datagrid has to be bound to a datatable all the time.I get a NullReferenceException with the following
Dim dt As DataTable
dt = CType(Me.grdDataGrid1.DataSource, DataTable)
Dim newrow As DataRow = dt.NewRow()
newrow(0) = 1100
dt.Rows.Add(newrow)
The error occurs on the line where dt.NewRow() is used.The problem occurs when the datatable (and the datagrid) is empty. If they have data, this works ok.What do I have to do to get this to work with empty datagrids?
I have files that start with unique numbers and are word documents. Say the document starts with "1234567" is there a way to make the OpenFileDialog filter to where only all the .doc files that start with "1234567" show up?
View 2 RepliesI'm working on an application, a GUI front-end for a command-line program. What I need to do is this:-use the OpenFileDialog to retrieve the command-line program's path (as it may be in different places for different users)-save that path string in a variable that I can use later (save "C: arget" in a variable called mainPath)
View 11 Replieshow do i set my initial value for textbox as blank. I tried to I load my textbox a data coming from my database but what my problem is that I need to set my default value for textbox as blank because everytime I load the forms the textbox will be filled immediately with data. This is how I bind my textbox and combobox after loading from database.
cbxJoblvl.DataSource = myDataSet.DefaultViewManager;
cbxJoblvl.DisplayMember = "Joblevel.lvl";
cbxJoblvl.SelectedIndex = -1;
txtLvlName.DataBindings.Add("Text", myDataSet.DefaultViewManager, "Joblevel.lvlname");

I've got a chapter I'm supposed to be working through and cannot access the template for a blank solution. My instructions are as follows:From the "File" menu, select "New", select "Project", select "Other Project Types", select "Visual Studio Solutions", and select "Blank Solution."
I can see File, I then see "New Project", but not just "Project". I click on this and my only choices are :
Windows Form Application WPF Application Console Application Class Library WPF Browser Application
I've tried searching the installed templates for "Blank Solution", "Solution", "New Solution" and have no results. I've looked around for a couple hours hoping for a way around this and no luck so far.
I use the following coding to replace a word in my textfile, would it be possible to add any coding that will remove all blank lines from the same text file?
Dim EditMyFile As String = IO.Path.Combine("D:Test.txt")
Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2")
IO.File.WriteAllText(EditMyFile, inputFile)
I have tried the following but it doesnt work.
Dim EditMyFile As String = IO.Path.Combine("D:Test.txt")
Dim inputFile = Regex.Replace(IO.File.ReadAllText(EditMyFile), "test", "test2")
IO.File.WriteAllText(EditMyFile, inputFile)
Dim sText As String = File.ReadAllText("D:Test.txt")
Dim sNewLines() As String = sText.Split(New Char() {ControlChars.Lf}, StringSplitOptions.RemoveEmptyEntries)
File.WriteAllLines("D:Test.txt", sNewLines)

My Visual Basic .Net 2010 application reads data from an EXCEL spreadsheet which will be generated by my "customers". The responses to Alkis last year (23 July 2011) has been a big help and got me over a hump in my application. Now I am down to the last issue - how do I detect a blank cell? Valid data is numeric, starts at a fixed cell (A5 to be specific), and will be continuous until it ends with blank cells. While blank cells appear to print a "zero", when I try to use zero as an end criteria I get a 'System.InvalidCastException'. When I put in a specific end value (-1) in the last cell all works fine but that, of course, is an invitation to a user error.What is the difference between "Value" and "Value2" and where might I find documentation that explains the difference?

View 1 RepliesI have an rdlc report that always produces the last page in blank. In this page, the header and the footer are printed but no data is shown (all data finishes in the previous page). I already checked and re-checked the horizontal and vertical printable areas and all the report definitions fit into these areas (if not, a blank page will be produced in between each page, I guess). If the report has one page, two pages are printed, if there are ten pages with data, eleven pages are printed

My users need to browse to select a file and then save it to a different location. Here's my code I've got so far - it incorporates the OpenFileDialog to open the file and the SaveFileDialog to save the file. When the code goes into the OpenFileDialog portion, it works great....the initial directory is set to "C:" This is where the user will select the file they want to save to another location.

The reason for this is that some users have different share drive letters.
