I am creating a program that uses XML files and saves them automatically when the user updates information. When I have XElement.Save("Name.xml") it saves the XML file in the same directory as the EXE. What I am trying to do is allow the user so select the location of the XML. Also is loading XML files through the loaddialog box basically the same way as XElement.Load("Name.xml")?
where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.
Private Sub GetReport() Try Dim hawbs As String = String.Empty[code]....
The retrieve document then does: the decrpytion gets the data(ids) and pulls the pdfs.

I am attempting to write a playlist for my media player which is already built. I have found a way to build a playlist for it but it would be helpful if I could save the contents of TextBox1 to a text file without using the save as. I am trying to get over a user inputting a file name for the finished text file so is it possible to write the file c: est.txt without using the save as dialog? I have found that I can use a vbs program file which creates a playlist in a folder. I save the vbs file text to the textbox then save it as a vbs file in the playlist directory, then execute the finished file to make the playlist.
I am trying to pull up a save file dialog, see code below:-
Shared Sub SaveAs() Dim StrPath As String = "" Dim strFile As String = ""[code].....
What I need is the folder location path of where I am trying to save the file, which I was hoping to get from strPath. The name of the file (which I can get from strFile)I also need the file extension which I was hoping to get from strExt
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]......
I am writing a Windows Form program to automatically download and store generated PDF reports from a web site using the WebBrowser Control. The web site uses Ajax to link an icon back to the source aspx file which then returns a PDF file.
The problem I have is that the WebBrowser control brings up the File Save As dialog box when the PDF file is returned and I can find no way of handling this to cature and save the returned file. I have found other examples of how to manage this using the Navagating event to validate the extension of the file that is being accessed (e.g. [URL] and, if not an HTM, file then use the HTTP Web control to directly download the file. Unfortunately this will not work as the call references a .aspx page.
I need to create a dotNet saveAs dialog, but I need to populate the file formats in the dialog. After the person have selected a file, it must connect that to a file format that I populate into the SaveAs command in the Excel Interop. After the Interop SaveAs command, I must check if the file have been saved correctly.

Currently I have three separate save commands in my program: Write to Plain Text, Write to HTML, and Write to Excel File.
Each one is invoked by a different command on a menu. I would like to combine these three into one Save File Dialog on the program. I know that I would have to edit the "Filter" property of the dialog box to add in the other two types.
My questions, how do I code the program to save the file based off what is chosen from the filter.[code]...

I have developed an application where some data will be automatically be updated in an Excel File. I need to autmate the application in a way such that there will be no manual user intervention.However once data is updated in the Excel file I get a save dialog prompt asking the user to save the Excel file. I need to know if there is any way to automate this part i.e. automatically save the Excel file and exit the application once data is updated.
