File I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?

Mar 17, 2010

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?

Save A File Data Using The Savefiledialog?

Feb 27, 2011

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

Saving Of Excel File With Savefiledialog?

Dec 4, 2008

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.

VS 2008 Scan A Long String And Return Any Values That Occur Between The Tags <FileName> And </FileName>?

Jul 1, 2009

Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:

ringlist = Mid(XMLRESP, (startloc + 1), (endloc - 1))
MsgBox(ringlist)

to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)

Dim patternstart As String = "<FileName>"
Dim patternend As String = "</FileName>"
Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)

Remove The Filename And Extract Just The Path Of The OpenFileDialog.Filename Property?

Oct 17, 2010

How would I do that? Sample code is below that demonstrated that the file I opened contained the full path and file name.

I want to extract just the path and serialize that to the user.config file as a UserSetting value. Then next time the user opens the dialog box, it uses that saved path string to go immediately to the location previously used.

If openFileDialog1.ShowDialog() = DialogResult.OK Then
Properties.Settings.Default.persistConnectionType = openFileDialog1.FileName
Properties.Settings.Default.Save();

SaveAs Dialog And Extensions - Allow The User To Select A Filename To Save A File Either As A Doc File?

Jul 1, 2011

I'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:

Dim dlg As New SaveFileDialog
dlg.InitialDirectory = m_sReportFolder
dlg.FileName = sProjectName & ".docx"[code]......

Get The FileName For The Proces.Start(FileName) Method?

May 27, 2009

I have a Listview on my form with different files. I can selet a file en open it with the proces start method. To open the file i use the OpenFileDialog method and select the filename. This work very good. With the code below.

My question is if there is a method to get the selected file without using the OpenFileDialog Box. So when i dubbelclick the selected file the proces will start with open the selected file. Something like:

proc.StartInfo.FileName = Me.SelectedCell.FileName
instead of proc.StartInfo.FileName = Me.OpenFileDialog1.FileName

PS) May be i can preduce the Filename using the OpenFileDialog method on the background.

Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick
If Me.OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then

Download A File With A Download Timeout?

I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.

Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?
