Saving Images Using SaveFileDialog?

Jul 1, 2011

I 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.

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.

Saving Images At Runtime?

Mar 18, 2010

I have been looking all over the internet for the answer to this question: How do you save an Image (actually a Bitmap) to an ImageList at runtime? I have an extremely simple image editor that I created to make the images I require for another program. I have incorporated the image editor into the other program. However I cannot figure out how to save user-created images in the ImageList I am displaying via ListView. If I am aimed in the right direction, I can usually find my way through the maze.Additionally, I may need to know how to select that image (I may be able to figure this out later).

Winforms Saving Images To SQL Server Without Creating A File On The User's Hard Drive?

Jun 22, 2011

This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.

Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.

Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?

Getting SaveFileDialog Error

Apr 14, 2010

[code]...

This code works on my local machine (Windows 7 Ultimate).When I tried it on WindowsXP,it didn't even open the dialog,instead it gave me an Unhandeled Exception error.

I can't remember the specific details of the error,but I do recall my profesor telling me there could be something wrong with permissions(me being the ONLY user on my machine,and his machine having multiple user accounts).

But what does all that have to do with opening the SaveFileDialog?

Could it be that SaveFileDialog1.AutoUpgradeEnabled = True is causing the problem?

My users need to browse to select a file and then save it to a different location. Here's my code I've got so far - it incorporates the OpenFileDialog to open the file and the SaveFileDialog to save the file. When the code goes into the OpenFileDialog portion, it works great....the initial directory is set to "C:" This is where the user will select the file they want to save to another location.

Savefiledialog 1.1 To 2.0 Conversion?

May 25, 2010

I have an .net 1.1 framework application I would like to update to 3.0 framework (or at least 2.0), but I've just run into a real problem. The savefile dialog code which works fine in 1.1 does not work in 2.0 and up. Line for line the code is the same (thereis no difference in line numbers at all). I'm baffled.With the exception of throwing an error for the Quicktime 7 control, VS2008 indicated no errors in converting 1.1I open my 1.1 (VS 2003) version and step through line-by-line. Works as advertised.I open my 2.0 (VS 2008) version and step through line-by-line. Appears to be working, dialog opens fine, I enter a filename, code continues; but when complete, there is no file in the folder.I'm wondering if the problem lies in the block of code for the small XML file I'm writing.
