I am searching for some code to help me take the bitmap contents of picturebox1 and convert it into an icon (*.ico) to save. I cannot for the life of me find anything to accomplish this. There are all sorts of codes that do things like convert bitmap files to icon files but nothing to change the contents of a picturebox as an icon.
View 2 RepliesI 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?

View 5 RepliesI'm trying to make a solid colored icon in Visual Basic.Right now I make a Bitmap, convert it to a Graphic in order to add color, convert it back to Bitmap, and then try to convert it to an icon.Unfortunately I cannot find any way to convert the final Bitmap to an icon. Can anyone help me with this? Alternatively does anyone have a different way to generate a solid colored icon? [code]

i've tried this code, which i converted from a create cursor function which worked ok with transparency. i'm guessing its the IconInfo hbmMask + hbmColor properties?

After scouring the forums for a code to extract icon from exe and convert to bitmap, i got that working, and the image will display on my form just fine. I want to save the image so it can be loaded again after the program is closed, but I get "Generic error in GDI+ occurred" when I attempt to save the bitmap.
Dim ExeIcon As Icon
Dim button1icon As Bitmap
ExeIcon = System.Drawing.Icon.ExtractAssociatedIcon(Filename)
button1icon = ExeIcon.ToBitmap()
Button1.BackgroundImage = button1icon
button1icon.Save("C:utton1icon.png", System.Drawing.Imaging.ImageFormat.Png)
I have a system icon (for example a folder icon) and I want to display it in a richtextbox. That's not a problem, but the transparency of the icon is gone and is replaced by a blue color. I tried to use the MakeTranparent function of the bitmap object, but with no luck. How can I make the bitmap transparent again?

I would like to convert an Bitmap image to an icon in VB.NET but I have to use the binary data of each to somehow accomplish that. Doing research on Bitmap I found how the files are structured. I know that bitmaps have the Bitmap Filer header, Bitmap infoheader, and the colorallet. Each of these contain a certain amount of bytes, and I a have to get these from the bitmap file. The icon header and info header are similar to the bitmap. I know that there are libraries in VB.NET that do that easily, butthis is for a project for school and I am not supposed to use that. I just want to ask how

I have made an application with a client, server and listener. The server is a console app and the other two are Windows Forms Applications.
Basically i am using a Network Stream to send messages from the client which go through the network to the server which bounces them to the listener which then reads the message and tells the app what to do. (For example if i sent "shutdown", the listener would read it and then execute "shell(shutdown -s)".
The messages are sent like the following SendMessage("shutdown") but when i use a screen capturing API and send from the listener to the client like so SendMessage(background) i get the following error:

Value of type 'System.Drawing.Bitmap' cannot be converted to 'String'.

How to possible the value of image in datagridview into byte format.
View 1 RepliesI have a SQLite database which is running on a handheld which is capturing signatures using OpenNetCF's Smart Device Framework 2.1 running under Windows Mobile 6.1. The signatures are captured from the Signature control using the GetSignatureEx method and stored in the database.
What I want to do now is reconstitute the signatures on the desktop, but the desktop does not have a similar control. I looked at the data and it looks like a bunch of vectors, which explains why the data is so compact.
how I can convert the data into a bitmap on the desktop using VB.NET.

The thing is mypath can be different between running the prog in the IDE and when it's installed, where is the best place for the icon, and what would the path be?

View 14 RepliesGot an annoying issue it's Visual Basic 2010 I changed icon where the assembly name.I got a good icon it has lots of sizes, or I tried diff sizes like 64x64 128x128 nothing seems to work I only see the icon when i do View > Details so it's small icons in the folder, but if i have view large icons It doesn't work. I even used the same icon on VS 2008 and it worked.
View 1 RepliesHere's the code that I use to extract the icon size that I want:
Dim i As Icon = My.Resources.Spectrum
Using i2 As New Icon(i, New Size(256, 256))
Me.PictureBox1.Image = i2.ToBitmap
End Using
This works from 16x16 up to 128x128 but for 256x256 it extracts the 128x128 icon. I tried 0x0, because I seem to remember that that is how the large size is stored in the meta data, but that didn't work either.
