I was trying to export a data from the listview control into an excel format and I was able to make it successfully using a command button directly. I want to use a SaveFileDialog to export and save the content of the listview. I searched from MSDN website and got a sample code which was originally intended for saving an image file. I tried to used it and edit the code and combine my code to export the data content. It ran successfully and attempt to export the data in an excel format but when you open the file in the path as to where you save the data, it gives you a message "Excel cannot open the file 'Filename.xlsx' because the file format or extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file." and it just leaves an empty excel file. I read from the MSDN site that if you are using an MS Office 2007, the file extension for excel would be '.xlsx' and not 'xls'. Let me give you the two codes I tried to use. First, I used command button and was able to successfully export and save the content in an excel format but using the SaveFileDialog was not successful. I suspected that there's something wrong within this line 'oBook.SaveAs("saveFileDialog1.FileName.GetType()")' and 'Dim fs As System.IO.FileStream = CType _(saveFileDialog1.OpenFile(), System.IO.FileStream)'.
Here are the two diffrent codes I used:
'Using the command button-----successful
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim oExcel As Object

Save RichTextBox Text to a .txt file With SaveFileDialog.I have a Rich Text box and a save filedialod and 1 button. what is the code to save the text that is in the rich text box to a .txt file??
I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

I have a VB.NET program with a SaveFileDialog control with the filter set as ".asx|*.asx|.m3u|*.m3u" (without the quotes). It works fine to save a file, but if I then try to save a file with the same name of an existing file and then change the extension in the save as type box, it still thinks I want to save the file as the existing file and asks to overwrite the file, disregarding the newly selected file extension.
I have tried setting the SaveFileDialog.FileName = Nothing after saving a file, so the Save File Dialog Box the File name box is empty, but then I like to click the existing file to get the file name I want, then select a new extension and try to save, but it still asks to overwrite the file with the other extension.
I hope my situation is clear and sorry if it has been already asked a million times...but can anyone point me in the right direction or tell me how I can save the file with the currently selected extension, not the previous selected extension when the file name was entered?
Code: If SaveFileDialog.ShowDialog = Windows.Forms.DialogResult.OK Then If Path.GetExtension(SaveFileDialog.FileName) = ".asx" Then ' Code Here to Prepare the CodeASX ...
I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:

I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.

I have a windows form application written using vb.net 2005 to generate and save an excel file. I faced some problems with the saving of excel file. The program will prompt a message box with 'Yes', 'No' or 'Cancel' options if the existing file exists. If user choose 'Yes', it will override the existing file. If user choose 'No', it will open a savefiledialog to allow user to specify the location and name to save the file. Do i use filestream object to save the file when user choose either 'Yes' or 'No'? How can i go about doing it or where can i find sample coding.

I have about 4000 objects of a class, each object with 20 members/variables, integers and strings, total about 80000.
I would like to save these to a file, and read them back into objects when the program starts up.
How would I do this in order to keep track of each variable? I was planning to have each line in the file representing the variables of 1 object. Hence 4000 lines. But basically I'm just looking for the easiest way to save and retrieve this data. Should I first convert the objects to an array of strings?

Tag and image files. All my files are .gif files and all have the same format. However, some of my 'objects' are located at different positions on the image. I would like to store the position in a Tag and save the Tag with the file. This is what I did..
Code:
dim pathload As string = "C:\myfile.gif") dim picViewer1 As New PictureBox Sub graphlocationsave()

I know the data get store in the Tag, but I do not know if its not saved, or I am not retriving it correctly or if this is the wrong way to do this altogether ?
