How do you save graphics drawn in a picture box to a file using a savefiledialog? I am using VB 2010. The code i used for the graphics (its for a painting program) are:
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
If down = True Then

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.

View 6 RepliesI am attempting to save a graph that I have displayed on the screen as an image file (e.g., a jpeg file) but the image I want to save has additional information such as axis labels that are not displayed on the screen. In addition, I also want to suppress some information that appears on the screen.
I create a separate bitmap canvas called mycanvas and I recreate my display on this canvas with the additional information. When I save it with an image format such as iftype=system.drawing.imaging.imageformat.tif with the command mycanvas.save(filename,iftype), I get the image file that I created on mycanvas. But If I use the SaveFileDialog followed by mycanvas.save(filename,iftype) I merely save the image displayed on the screen. It is as if my graphics object has reverted back to the graphics object I was using for the screen display.

View 5 RepliesI'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 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

I have a problem when trying to save a picture box image ( I am using vb2008 express edition)When i load my windows form I create a folder called images and the current date (eg images 24062011) using the following code.
Code:
Dim fold As String = "images" & " " & Format(Now(), "ddMMyyyy")
If My.Computer.FileSystem.DirectoryExists("C:usersmickdesktop" & fold) Then
MsgBox(" file exists")
[code].....
this works fine and creates the folder on my desktop. I then load an image into a picturebox and try to save it using the following code which is where the problem starts.
Code:
Dim filename As String = Format(Now(), "ddMMyyyy")
Dim imagename As String = "image"
Dim fileext As String = Drawing.Imaging.ImageFormat.Bmp.ToString
[code].....
so my problem is why does the 1st statement give me the error as surely as I have declared that fold = the folder name then that path should be correct, as the program is set to save the image automatically, not using the savefiledialogue I don't want to have to manually type in the folder name every time I use the program.

Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?
View 1 RepliesI have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.
We have a GIS application that has some performance issues. It creates and sends an image to a web browser. We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.
The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.
So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost? It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.
