Re: byte array to image harold aptroot8-Jul-09 5:15 harold aptroot 8-Jul-09 5:15  Maybe it's bigger than 1024 bytes? Also, why do you use the memorystream .. for nothing? You could write the array directly to the stream (or if File.WriteAllBytes is available, that's even easier) Re: byte array to image Vivek Vijayan8-Jul-09 5:23 Vivek Vijayan 8-Jul-09 5:23  how do i get byte array from the an image with out using memory stream This code was posted by me... Re: byte array to image harold aptroot8-Jul-09 5:26 harold aptroot 8-Jul-09 5:26  Scanning the pixels, but I was referring to the receiving code, which doesn't use the memory stream for anything other than the WriteTo method Re: byte array to image Vivek Vijayan8-Jul-09 5:49 Vivek Vijayan 8-Jul-09 5:49  what is the other way...but i m not able to open the image using the code pictureBox1.Image =new Bitmap("\\Program Files\\pic\\screen.Bmp"); and pictureBox1.Image =File.Open("\\Program Files\\pic\\screen.Bmp", FileMode.Open, FileAccess.Read));its raising exception "Exception" This code was posted by me... Re: byte array to image harold aptroot8-Jul-09 6:01 harold aptroot 8-Jul-09 6:01  Well if you have that filestream you can just fs.Write(buffer, 0, 1024) Assigning a stream to the Image property should not even compile though Re: byte array to image Vivek Vijayan8-Jul-09 6:09 Vivek Vijayan 8-Jul-09 6:09  i m getting exception when i load to picture box This code was posted by me... Re: byte array to image harold aptroot8-Jul-09 6:20 harold aptroot 8-Jul-09 6:20  Are you sure? Maybe you are getting it when you load the bitmap? You'd have to put it on 2 lines to know that. Re: byte array to image Vivek Vijayan8-Jul-09 6:32 Vivek Vijayan 8-Jul-09 6:32  exception "Exception" is caught on loading the image. why it is happening?? and wht type of exception is this This code was posted by me... Re: byte array to image Vivek Vijayan8-Jul-09 6:49 Vivek Vijayan 8-Jul-09 6:49  sorry the exception is not cought on loading its in ht eline picturebox1.image=new Bitmap(fs) where fs is file stream This code was posted by me... Re: byte array to image Vivek Vijayan8-Jul-09 7:00 Vivek Vijayan 8-Jul-09 7:00  NullReferenceException is caught in the line fs=File.Open("\\Program Files\\pic\\screen.Bmp", FileMode.Open, FileAccess.Read); pictureBox1.Image =new Bitmap(fs); This code was posted by me... Re: byte array to image harold aptroot8-Jul-09 7:07 harold aptroot 8-Jul-09 7:07  So.. fs is null? AFAIK that can never happen, it would have to give an other exception as detailed here: File.Open on MSDN[^] I don't know what else? Re: byte array to image Vivek Vijayan8-Jul-09 8:16 Vivek Vijayan 8-Jul-09 8:16  i don knwo wht is happening,The file is created. that i can see when when i browse the folder. but null reference exception is shown when i run applcn. This code was posted by me... Re: byte array to image harold aptroot8-Jul-09 8:42 harold aptroot 8-Jul-09 8:42  Is the file ok? does it open in, say, paint without error? Re: byte array to image Vivek Vijayan8-Jul-09 10:07 Vivek Vijayan 8-Jul-09 10:07  no there is error in opening its telling something like invalid data....how firts i need to convert byte array or memory stream to image....thats the problem persisting............. This code was posted by me... Re: byte array to image Vivek Vijayan8-Jul-09 18:34 Vivek Vijayan 8-Jul-09 18:34  i got it correct!!!! the error was in writing to file thanks!!! This code was posted by me... Re: byte array to image harold aptroot8-Jul-09 3:18 harold aptroot 8-Jul-09 3:18  You know, it's actually easier if it's "just pixels". Then you can just make an empty bitmap and write the pixels to it yourself. But you had best find out, because it really is a very important difference.. click once or create MIS package Abdul Rahman Hamidy7-Jul-09 20:41 Abdul Rahman Hamidy 7-Jul-09 20:41  Dear All, I have developed different application and create it msi package for them, but this time its alittle bit different. now i have developed an application which can be used over 34 provinces of afghanistan and monthly there will 2 or more updates for each province, so this mean that each province may have updates or not that depends. i am asking which method of installation should i use? 1.creating msi package 2. creating by clickonce my concern is always updates, i should be able to send them only udpates whenever the require not the whole setup file. Abdul Rahaman Hamidy Database Developer Kabul, Afghanistan Re: click once or create MIS package SeMartens7-Jul-09 21:28 SeMartens 7-Jul-09 21:28  Hi, I guess that you have one single application that must be configured to fit in for each of the 34 provinces. If it is that, I would use clickonce, because click-once contains the distribution itself. Other way would be to write an application that contains the update mechanism itself, like an antivirus-app. There are different patterns and frameworks for this, so it should be easy to find a good starting point. Regards Sebastian It's not a bug, it's a feature! Check out my CodeProject article Permission-by-aspect. Me in Softwareland. Re: click once or create MIS package Abdul Rahman Hamidy7-Jul-09 21:53 Abdul Rahman Hamidy 7-Jul-09 21:53  thx my friend, the fact that each province uses its own version and a single update to any province should be distributede for 34 provinces. i would really appreciate to have some reference regarding update mechansim as u mentioned for antivirus or can i use ".cab" from VS setup for my deployment? Abdul Rahaman Hamidy Database Developer Kabul, Afghanistan Re: click once or create MIS package SeMartens7-Jul-09 22:01 SeMartens 7-Jul-09 22:01  MS published a pattern and practices-article about self-updating applications: http://msdn.microsoft.com/en-us/library/ms978574.aspx[^] Have a look, it is quite interesting. Didn't get it that each province has its own version. You mean you implemented ONE application, but to fit for the province it must be CONFIGURED? It's not a bug, it's a feature!

Re: click once or create MIS package Abdul Rahman Hamidy7-Jul-09 22:19 Abdul Rahman Hamidy 7-Jul-09 22:19  thx, i mean the application is only one, but is installed in 34 provinces, if one provinces finds any bug or error in the application, that error needs be fixed and reflected to all provinces. Abdul Rahaman Hamidy Database Developer Kabul, Afghanistan Re: click once or create MIS package SeMartens7-Jul-09 22:23 SeMartens 7-Jul-09 22:23  Ah okay, sounds good. Well as mentioned before, click-once will suit your requirements perfectly. It's not a bug, it's a feature! Check out my CodeProject article Permission-by-aspect. Me in Softwareland.

We have a set of string say a List<objects> of a class with string data. We need to print it. What is the best way out, keeping it lightwieght and simple. Thanks Re: Print Help dan!sh 7-Jul-09 21:00 dan!sh 7-Jul-09 21:00  If you are printing reports, go for ReportViewer control or Crystal report. Or else in-built classes to print data would be best bet. There is a WPF/WCF[^] forum here. IMO that would be better place ask.
