I am creating a very simple game for a project. There is opportunity for bonus marks, and one thing I would like to do is be able to "save" the game. The only thing I need to do is save about 4 variables to be recalled the next time the program runs.
What is the best way to do this?
I have searched Google, and there are ways to link the program to an Access database, but that seams a little extreme. I tried seeing if you can make an XML file to hold them, but I can't really find any good information.
I have a complex form to allow the user to configure my app.
What's the best way to save the form state & reload when the program next runs.
I mean text he has entered in list boxes, the selected item of combo/list/radio, whether a checkbox is cheeked, etc

I need to save Bitmap object loaded from image file (.png, .jpeg, .bmp) and save it as an icon (.ico) to a separate file.
First I tried saving Bitmap object to a file with Icon ImageFormat:
using System.Drawing;
Bitmap bmp = (Bitmap)pictureBox1.Image;
bmp.Save(@"C:icon.ico", Imaging.ImageFormat.Icon);
This one fails, as the icon produced is not in a proper format and it cannot be used as an icon.
Next one was to get HIcon from Bitmap and save it to a file:
using System.Drawing;
using System.IO;
StreamWriter iconWriter = new StreamWriter(@"C:icon.ico");
[Code]....
This one does not do the job too. Although icon file is properly written, it has only 16 colors and a limited width and height.
I'd like to be able to write icons with custom width and height that would preserve colors from the original image. Is this possible to achive in .NET?

I've created a new bitmap object and am shading some pixels inside it black using the setpixel function. At the end I do:
myBlankBitmap.Save("D:3Didea_out.bmp")
Great. Except the bitmap that is saved is 32bit and won't open properly. I want it to be 8 bit. I can't find any options to change the bitdepth.
I knew everything I needed to save an image, so I type in my code, and yet another error pops up. Here's the bit of code:
screenshot.Save(CaptureMain.picLocation.ToString, Imaging.ImageFormat.Bmp, "Screenshot")
And, the error's kind of lengthly...

Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:

I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

how to override the page_load or any other base page event every time in an application? I keep finding half examples and answers around the web. I want to fire this method every time a page is loaded.
View 2 RepliesI am upgrading a 1.1 web app to 4.0 and am running into an issue with the page_load of a custom user control firing twice, both being treated as non-postbacks (IsPostBack is false in the case). I have read around and it seems that there are 2 culprits to this, 1 being an img tag without something in the src part (which there are no images on this page at all) or 2 an issue with AutoEventWireup and Handles being used at the same time. I have looked through all my code and there are no Handles keywords in there at all and AutoEventWireUp is set to true on every page, yet I still get this issue.

Basically, I'm trying to get the Page_Load subroutine to execute on the page load, but it doesn't seem to be called. I'm assuming that because I set my feedback label to "feedback" in the Page_Load subroutine, I should see it displayed on the page saying "feedback" on first loading the page and every time I refresh. But this doesn't happen. I'm lead to conclude that the Page_Load subroutine is not being called on the page load.
