View 14 RepliesI 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 have the following code that generates a csv file on a button click. [Code] What I want to do is open a download dialog box that will allow the user to open or save that file it has just created.

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 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?

Here are some important facts:
This code works (no Error 1004 on numerous laptops and desktops) A couple of months ago it began to fail (Error 1004 reared it's ugly head) on a couple of machines. The users claim that nothing changed - I can neither confirm nor deny accuracy of these claims. All users, except one, are running Windows XP and Office 2003. The problem also surfaced on a new machine running Windows XP and Office 2007. I could not force the error on my development/test machine - Windows XP with Offic 2003. It fails every time on another machine I have running Vista with Office 2007
The following is the code that causes me the problem. I know the error is raised on the WB.Save statement. I added the error trap to eliminate the problem of the Excel file being unaccessable without a reboot, due to the fact that Windows thought Excel still had it open.

View 5 RepliesI 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
