Have you read the documentation for it? Have you even attempted to look up the documentation?

Create a Graphics object for the image (using Graphics.FromImage), and use that to draw the text on the image.

He just told you how to do it. Do you always ignore the answers you're given??

i've made a quick example for you, i think people forget they come on these boards to help people out when they start giving out sharp answers instead of just helping with a code snippet that only takes a moment to make.

Code:

<br />
        <font face="Courier New" size="2"><font color="#008000">   '/// load original image from file as a Drawing.Image...</font><br />
        <font color="#0000FF">   Dim</font> img <font color="#0000FF">As</font> Image = Image.FromFile("<a href="file:///C:/Image1.png">C:\Image1.png</a>")<br />
        <font color="#008000">   '/// get hold of the Graphics object...</font><br />
           <font color="#0000FF">Dim</font> g <font color="#0000FF">As</font> Graphics = Graphics.FromImage(img)<br />
<font color="#008000">   '/// draw the String on the image...</font><br />
           g.DrawString("some text on an image!", <font color="#0000FF">New</font> Font(<font color="#0000FF">Me</font>.Font.Name, 16, FontStyle.Bold), <font color="#0000FF">New</font> SolidBrush(Color.Red), 10, 10, <font color="#0000FF">New</font> StringFormat(StringFormatFlags.DirectionVertical))<br />
        <font color="#008000">   '/// save as a new image so as to NOT replace original...</font><br />
           img.Save("C:\testing.jpg", Imaging.ImageFormat.Jpeg)<br />
        <font color="#008000">   '/// clean up...</font><br />
           g.Dispose()<br />
           img.Dispose()<br />
        <font color="#008000">   '/// test out on a picturebox to see if it's worked ( you could skip this & just look for the file )...</font><br />
           PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage<br />
           PictureBox1.Image = Image.FromFile("C:\testing.jpg")</font><br><br />

hope it helps Smile | :)

And what do I want with a code sample? I'm not the one looking to mark an image.

You missed the point of my post. He asked a question, got the description of how to do it, and then repeated his question, without saying anything about what he was having a problem with.

All to often, there are people who come here and just want the code written for them without having to lift a finger themselves to write it. That's why he didn't get code sample. He has to show that he at least attempted to solve the problem on his own. Then we'll go through and show him where he went wrong.

erm, i wasn't giving a sample to your good self, i was aiming it at the person who asked for help. didn't realise it was a touchy subject to post code, sorry. i just presumed that it was ok to help people when they ask for help on a forum. the sample i posted was just a very basic guide to point them in a direction, not war in peace.
anyway @ the guy who originally posted for some help - hope it helped just a little Smile | :)

Dave Kreskowiak, i never saw anywhere in my post that i was aiming that code at you. my interpretation of the reply post by the guy asking for help was that they thought they had to make a new image, then add the existing image to that & the text also to the new image. i don't think they understood that they can get the image, modify it & save it to a new path ( rather than replacing / losing the original )

Maybe you didn't know this, but the only person who gets an email that you responded to a message is the person you are replying to. Everyone else in the chain does not get a notification that you posted anything. So, I'm the only who got a notification that you responded to my post.

if you want to change the format you display on the screen then use
folloeong function

e.g you want to display te date in the textbox then

textbox.text=format(now.date,"DD/MM/yyyy")

In the same fashion you can use any format of the date.

Those are date formats. Don't you want that?

There is only one DateTime type, it's System.DateTime and it's specified in the mscorlib.dll. It's the same for all systems, so there is no special DateTime type for any specific system.

If you want information about the current date format for the user, use CultureInfo.CurrentCulture.DateTimeFormat to get the DateTimeFormatInfo object that describes the date format.
