Re: How to update a class property with a timer pusch3-Jul-07 6:04 pusch 3-Jul-07 6:04  -So I would stick with the simple Station propery and let the app do timing and GUI stuff- I think its a clean solution! Thank you very much pusch Re: How to update a class property with a timer Jimmanuel3-Jul-07 5:47 Jimmanuel 3-Jul-07 5:47  The System.Timers.Timer has a SynchronizingObject[^] property. This can be used to make sure that the timer callback function is called on a specific thread. Maybe this will help . . . Re: How to update a class property with a timer pusch3-Jul-07 6:15 pusch 3-Jul-07 6:15  this is what I was looking for! May be it is not the best solution for my posted question, but its exactly what I had in mind. Thanks a lot. regards pusch Text Disappear From MessageBox Himanshu_ITDevloper3-Jul-07 2:37 Himanshu_ITDevloper 3-Jul-07 2:37  Hi, I have written simple code in click event of button as below MessageBox.Show("HI"); When I run the application, I got the blank messagebox means it doesn't have the message text "HI" and also doesn't display OK messagebox button. Anybody have any idea. Please guide. Any type of help is appreciated. Himanshu Batavia Re: Text Disappear From MessageBox Dave Sexton3-Jul-07 2:58 Dave Sexton 3-Jul-07 2:58  You only need to post your question once. Someone will answer eventually. Your code should look something like this private void button1_Click(object sender, EventArgs e) { MessageBox.Show("Hello"); } I would seriously suggest buying a book and working through it to get started in programming before looking for help online. Learn the basics first. I think I'm going to call my next project "Chuck Norris". It's a sure way to guarantee it's unbreakable. • • • But fortunately we have the nanny-state politicians who can step in to protect us poor stupid consumers, most of whom would not know a JVM from a frozen chicken.

But when I run the program and click on Button1, I get the messagebox but having no output means I don't get "Hello" text and also don't get OK messagebox button. Why it is so? Any type of help is appreciated Himanshu Batavia Re: Disappear Text From MessageBox Judah Gabriel Himango3-Jul-07 4:34 Judah Gabriel Himango 3-Jul-07 4:34  Sounds like your code isn't working right. Are you certain the button1.Click event is setup to be handled by your handler function? You should show us the appropriate code. Tech, life, family, faith: Give me a visit.

This link[^] takes you to the specification. Be aware though that there are *many* different versions of JPEG, so you will need to test this thoroughly.

Re: fetch jpeg image dimension without load it small_programmer3-Jul-07 2:39 small_programmer 3-Jul-07 2:39  thank you a lot. but this site does not offer any C# code and I can't find image dimension obviously in it's jpeg header format. thank you again. if any one have more simple answer please send it. thank you again.

It's the jpeg format only. What you need to do is read in the file, a byte at a time until you read in the Xdensity and Ydensity bytes (each of which is two bytes). If you read in the first 18 bytes, the 14th will tell you the JPEG unit, the next two will be the X density and the last two will be the Y density.

Re: fetch jpeg image dimension without load it small_programmer3-Jul-07 3:00 small_programmer 3-Jul-07 3:00  thank you . but can you offer a formula between density and unit that result in the height and width in pixel. if you do it i will thank you very much Re: fetch jpeg image dimension without load it Colin Angus Mackay3-Jul-07 3:43 Colin Angus Mackay 3-Jul-07 3:43  Well, according to the link. If units is zero then Xdensity and Ydensity are already in pixels. If it is 1 or 2 it is in dots per inch or cm respectively. You will then need to find out the dots per inch/cm on the output device and scale appropriately. For example, if the image is a photo at 300dpi and it is to be displayed on a screen at 96dpi then you need to reduce the number of pixels by source/destination or 300/96 (3.125) Upcoming events: * Glasgow: Mock Objects, SQL Server CLR Integration, Reporting Services, db4o, Dependency Injection with Spring ...

Re: fetch jpeg image dimension without load it [modified] small_programmer3-Jul-07 4:50 small_programmer 3-Jul-07 4:50  it does not give me the height and width in pixel yet. i want only height and width. unit and density does not help me thank you again. How to save images into Access DataBase AR Reddy3-Jul-07 2:15 AR Reddy 3-Jul-07 2:15  Hi, I want to save the images into Access database in C#. Please give ne the sample piece of code if you have or give me the related links. Thanks in Advance, AR Reddy Re: How to save images into Access DataBase WhiteGirl233-Jul-07 2:34 WhiteGirl23 3-Jul-07 2:34  Hi, to save images in access first transform them in bytes and then insert them in access. Re: How to save images into Access DataBase Dave Kreskowiak3-Jul-07 6:46 Dave Kreskowiak 3-Jul-07 6:46  There's a bazillion examples out on the web. All you have to do is Google for "C# save image access database".
