I'm trying to save an excel file:
vb.net
xlWBook.SaveAs("J:DOWNLOADS.xls")
xlWBook.Close()
xlApp.Quit()
If the file already exists excel will open an message box and ask if you want to overwrite. If I click yes, it works. If I click no or cancel, I get an error:
Exception from HRESULT: 0x800A03EC
How can I tell what button the user clicked?
How do I have it overwrite the file if it already exists with My.Computer.Network.DownloadFile?
Here's the code for where its needed but, this is not all of the code
My.Computer.Network.DownloadFile _
("http:mirror.cc.vt.edu/pub/mozillaseamonkey/releases/1.1.14/seamonkey-1.1.14.en-US.win32.installer.exe", _

I am trying to create a wpf program that allows the user to create custom shapes or pick premade shapes and that after making their selection, a canvas shows their shapes randomly sized, positioned, colored and copied in multiples. I am hoping that on click, the program will put its output on a time interval and that the user can click stop when they are satisfied with how everything looks. My issue is, I would like to also give the user an option to save their created artwork as a jpeg file. Also if I wanted to link this file to a web browser what will I have to do?

I keep getting an error saying "Unhandled exception has occurred in your application." Then the next paragraph says "The process cannot access the file 'E:Copy of Release+Fontsob.txt' because it is being used by another process."
I have a couple of files which I have to update periodically through a process written in VB.net . These files are on a server and part of a domain that many users can access. These files should never be written to as they are for reference only. I need to be able to overwrite some of them even if a user has them opened. Is it possible to do this? Presently the files permissions are not set as read-only but I can do this as long as the user under which the process runs will still have permission to overwrite them.
UPDATE: thx for your responses. The files are pdf and are opened by clicking on them from windows file explorer. This also happens when a user simply has the file selected in windows explorer.
I am writing a text editor program and I have written the new, open, save as, exit menu items but I am struggling with writing the save option.Now I have created the menu itself (well vb did, I just used insert standard items) but how do I code up the save menu option so that it updates the current document or if the documnt has not yet been saved bring up the save file dialog.Here is the code I have so far

I know I have some finishing touches such as messages and error handling and stuff but at the moment I want to get all the basics working,I think the save menu option is all I am struggling with at the moment.

I have researched the net, youtube, and the msdn DB, and still can not find the working answer I am looking for. I would like someone to show me how you would save the contents of "Listbox1" to a .txt file using the "Save As" Option. I know how to hardcode a savepoint in, but since there will be multiple users I would like the option to be up to the end-user.

I have a number of word documents I am converting. Everything is going great until I get a file that is read only. In this case I get a Save As prompt.
Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.
I'm using VB.net to open the files. More specifically
doc = word.Documents.Open(path, Type.Missing, False, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing)
I have a simple program that opens up a text file and changes it and then what I want to do is save a text file when you click the "convert" button to the directory that the exe exists in e.g. "C:UsersBeaudeanDesktop--Distro--" etc. so say I have a richtextbox with the text in it I want to save and a button called "convert", when I click convert it will save it in the programs root folder with the name "main.html" and I also want it to overwrite any file with the same name.

I have some code that fills my datagridview (VulDgv) I also have some code that exports the datatable to an excelfile (DatatableToExcel). All works pretty good. However...when I export to an existing file I get 2 warnings, first is the "file exists overwrite" warning from the savefiledialog. The second message is the "excelfile exists" from excel itselve. (is it possible to hide this message?) My real problem is after the 2 messages the code APPENDS the data to the excel file instead of overwriting it.

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

View 2 RepliesI'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:

View 1 RepliesI'm trying to import data from an Excel file into SQL server. However, the Excel file's format is not recognized by SQL Server. In fact, when I open it and try to save it, I get the following message:<filename> cannot be saved in the current format. To save your changes, click OK, then save it as the latest format.When I do that manually, it puts it in a usable format. However, the automated process I'm trying to build can't save it without intervention. When the VB in my SSIS process gets to it it brings up a save window, and I have to click the "Save" button and then the "Yes" button to replace the existing file. I'd strongly prefer to have this automated. I've have tried using the SendKeys.Send("{ENTER}") code, but it brings up this message:SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.I've tried SendWait, but it just seems to hang. I don't know how to change the application to handle error messages. I have also tried saving the Excel file as a new file with my VB code. However, as a new xls, xlsx, and csv file it still wasn't recognized by the import. I've only had success when manually saving it. In the SaveAs code I have been using, I'm only using the FileName parameter. I can't get any FileFormats to work or be recognized. Note, though, I'm opening the app and worksheet as Object variables. I can't add the Excel component in the Add Refrence area because only the .NET tab is there. I don't have a COM tab. I haven't asked if/how to get access to it, though.
