Saving a picture without manually choosing the location?

[Karl.Green]

I'm making a screen capturing program, and I am trying to save the image. I can do it as a 'save as' like this

savefiledialog1.Title = "Save File"
            savefiledialog1.FileName = "Capture"
            savefiledialog1.Filter = "JPEG (*.jpg;*.jpeg;*.jpe;*.jfif)|*.jpg;*.jpeg;*.jpe;*.jfif|PNG (*.png)|*.png"
            If savefiledialog1.ShowDialog() = DialogResult.OK Then
                PictureBox1.Image.Save(savefiledialog1.FileName, System.Drawing.Imaging.ImageFormat.Bmp)
            End If

How could I do a quick save option so that it auto saves to a certain location that the user doesn't have to choose and as a .jpg?
Sorry if it's really simple, I've only recently started learning it at college

You are using a save file dialog so obviously it will ask you where to save the file. That's the point of it.

PictureBox1.Image.Save(savefiledialog1.FileName, System.Drawing.Imaging.ImageFormat.Bmp)

savefiledialog1.FileName is the path and file name. Hard code that.

Side note look at your last entry. "System.Drawing.Imaging.ImageFormat.Bmp"

I can do the file name, I am unsure how to add the location in?

I have

quicksave.FileName = "screenshot" & intCount + 1
 
        PictureBox1.Image.Save(quicksave.FileName, System.Drawing.Imaging.ImageFormat.Jpeg)

and I want it to save to "C:\Users\Karl\Desktop\Screenshot"?

What is this quicksave.filename and intCount +1 all about? As i previously said you need to hard code the location. When i say hard code write the string value exactly as how you would see it.

For example if you wanted to save the picture from multiple instances in your application with possibly a different location each time you can make a new method as such.

Private Sub SavePictureBox(ByVal path As String)
        PictureBox1.Image.Save(path, System.Drawing.Imaging.ImageFormat.Jpeg)
End Sub

Now when calling this method you would pass an argument.

SavePictureBox("C:\Users\Karl\Desktop\Screenshot\filename.jpeg")

PictureBox1.Image.Save("C:\Users\Karl\Desktop\Screenshot\filename.jpeg", System.Drawing.Imaging.ImageFormat.Jpeg)

Ahh thank you, I misunderstood the first time, it is working now.

The intCount is the number of files in that folder, so by adding 1 to it, it should be a unique filename.
I did it like this to include the intCount

PictureBox1.Image.Save("C:\Users\Karl\Desktop\Screenshot\" & quicksave.FileName & ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

If you want an unique count why not time stamp it? But still what is this quicksave.filename? Can you please post your full code.

        PictureBox1.Image.Save(String.Format("C:\Users\Karl\Desktop\Screenshot\{0}{1}.jpg", quicksave.FileName, intCount + 1), System.Drawing.Imaging.ImageFormat.Jpeg)

I can't remember why it was originally called "quicksave.filename" it is now strFilename

btw - there is a set of methods available that will combine paths and filenames - part of the System.IO namespace

they work like this:

Dim strReportFolder As String = System.Web.Configuration.WebConfigurationManager.AppSettings("reportfolder")
Dim strStagingFolder As String = Path.Combine(strReportFolder, "staging")
Dim strBusyFile As String = Path.Combine(strStagingFolder, "Busy.txt")

That first Dim gets the path from a web.config file - you could just as easily hardwire that but if you are going to run this app elsewhere you need a way to make that more "variable"

  <appSettings>
    <add key="reportfolder" value="D:\ACS Desktop\AWC\reporting"/>

When you say to use the variable if I want to use it elsewhere, I have now changed it to use environment.username instead of "karl". I am not sure if that is the same thing but programmed differently or if you are talking about different?

You are hardwiring Desktop\Screenshot though - if it's a personnal use app - or you can force people to create a folder on their desktop (some would say a desktop should only have SHORTCUTS - never a folder) then you have no issues.

Otherwise you should put the path in your app.config files - winforms have one of those - right?
