Thanks.. its is working ohk...

but still i want to ask you if image folder is not resided in same folder where .exe reside...then which syntax i should use?

How it is possible to place image folder in debug folder...i mean i am not putting data in image folder it is default created by some other application... Am i correct as you are talking to cut Image folder from where it is now and paste it into debug folder????

hi my cn.open is working ok.. i trace it by using eventlog. .. I guess i am doing mistake

in string ImgExist = Path.GetFullPath("~/Images/") + stamp + ".jpg"; syntax as it fins windows path..... In web application i was using server.mappath but in windows i guess problem is there.... so if we want to retrive file from specific folder which is in webservice how to retrive it....

i am bit confused how to write that syntax to get path of image folder which is in same where my .exe lies.. say Imageresizer is my service name then image folder lies in Imageresizer/Imageresizer/Image...where my exe is in Imageresizer/Imageresizer/bin/Debug/Imageresizer.exe

yes in the same path.. can you please write whole code for that syntax.. i am bit confused how to write that syntax to get path of image folder which is in same where my .exe lies.. say Imageresizer is my service name then image folder lies in Imageresizer/Imageresizer/Image...where my exe is in Imageresizer/Imageresizer/bin/Debug/Imageresizer.exe

Thanks your I trace code as you suggested... I found connection is okay but proble is with
string ImgExist = Path.GetFullPath("~/Images/") + stamp + ".jpg";

same as i discussed with you previously what to use in place of server.mappath..i tried gettfullpath syntax and i guess it might be not working as the way i want......

yeah i trace code by using eventlog.. connection is working fine but the problem is with.....

string ImgExist = Path.GetFullPath("~/Images/") + stamp + ".jpg";

in web application i used Server.mappath to retrive virtual directory image file. but in windows service i dont have any clue... so can you tell me if we want to retrive image file from specific folder then how can i do it...have you any idea?

need to add logging mean? i am not getting. I am very new to windows service so can you please explain it further. As i have no clue where i am wrong...

I narrow down the above code.. I tried that by putting server name but it is also same . I am not getting where i am wrong...

In that case is it required to change connection string ? or it is fine for my program also.

But the same connection string is working absolutely okay in web application then why not in windows service. still if you suggesting then i will try it by doing change. I am using MS SQL server

I gave database name as well as username and password also..

No i didnt go for sql trace. As same code is working okay in web application so there shoould be problem in calling the connection or initialization in program it self and thats why i posted whole coding here....

i have posted connection string in first part of code from app.config file

i tried using thread also but it gives same error. yeah if i am remiving code then i can start service.....

oh i am really sorry i post it as a answer link...but do you have any idea about my issue?

but still it is not working.. i need help

I am still not getting your point.I am very new to windows service. I want same functionality in my windows service as it is in my asp.net web application.

It haven't any UI.

I am briefing my web application here so according to that you can guide me how to do it in windows service.

Retrieving very Big image from IMAGE folder which resides in my web application according to certain condition.

Resize those image and store it into database.

Retrive resized images stored in database and store it into server folder called Large and again resize that image in 3 more different size and save into their three respective size folders called List, Mini,*Thumb* on server.

Now i want to build windows service with same functionality and it run on server after every 15 mins.

Hope now i am more clear. please help me in this regards.

my web application code is working fin. but i don't know where to put this code in my windows service as I am very new to windows service.

I tried to put that code onstart and also oncontinue method but that time service not allowed to start. It gives error message this service can not start on your local machine.

What does it mean? I am not getting you point.

W:\nilam\Proj1\WindowsService1\WindowsService1\Images

As of now it is in my windows service project folder.. sorry if i am doing really foolish thing because i have no clue for windows services.

i stuck in very beginning at IMAGE folder,how to get path of it and retrive image from it. i was using all the time only server.mappath to retrive the file and store the file

if i solved it then may be will solve all issue hopefully...

My proj is

1.Get Big image from folder called IMGAE according to certain condition
2. Resize those images store it into database
3. Retrive that resized image and store it on server disk folder called LARGE
4. Again resize image from LARGE in 3 different size and store it in respective 3 different folder.
5. This process continue


I did all this in Web application in asp.net but in windows service point of view i am not getting how to get images from file which i was getting in web app through server.mappath

then how will i set my folder from which i need to extract files...

i need image file which resides in image folder in windowsservices.

string ImgExist =Assembly.GetExecutingAssembly("~/Images/").CodeBase + stamp + ".jpg";

string ImgExist =Assembly.GetExecutingAssembly("~/Images/").Location + stamp + ".jpg";


I tried both option but it says no overload getexecutionassembly takes only 1 argument.

no it is not working... :(

yes but there is one block only for connection string not so many setting like in web.config

oh thanks, I got it, it is System.Configuration only not configuration manager so i was bit confused.
one more question to retrive file from directory which resided in webapplication i was using server.mappath but for windows service its not supported. then how will i retrive. also in webconfig i have set max length for image(size to load)and execution timeout but in app.config can i set it same way???



thanks a lot for your help...

I created app.config file but it has just following coding so how i can use other setting which i did in web.config file in webapplication.


<configuration>
connection string i have added::::::
<add name="b1" .......="" providername="System.Data.SqlClient">

i mean if i am adding reference then it required source dll file . so form where i can get it??? should i download form internet or what not getting.

no i am not able to find app.config file in my windows service ,
how to add reference System.ConfigurationManager 3.0 version.. I mean source or smthing like

i have also read the same. but how to get app.config file. I know to create web.config but not about app.config.

also there is System.configuration is available in web service. but it is not supporting configurationmanager.

Hi Thanks,

Connection string which i stored in web application web.config file.Working fine in web application but not working i windows service as it is not supporting System.Web.Configuration. Below is code to call in to windows service:

SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["b1"].ConnectionString);

not working also server.mappath() is also not working. so what to write their place?

I am retrieving image from Image(Image folder in my Webapplication1) which lies on my disk according to certain condition.

After that I am resizing those image on page_load event of source_page.aspx(Lies in Webapplication1) and storing resized image in Resized(Folder in my webapplication1)folder. At that time it store image in .jpg format not in bytecode.

Also same time I am making resized image in byte code ( as i am not sure which i can easily pass to targetpage_aspx.)

I want to post that image on target.aspx(lies in webapplication2)page. where it will further resize image in three different size and store in local disk or first_receive(Image folder in webapplication2).

I am not worried about further resizing that i will do. Here i am assuming that resized image i want to store in folder(in webapplication2).

So question is how to pass that resize image from Sourcepage.aspx(Webapplication1) and how to receive it on Targetpage.aspx(Webapplication2)?

Hope now i am bit more clear in my question..

I have gone through your sample. I have resized image and store it in byte code.
Now I am not getting what to do next?

and also in which webpage sourcepage.aspx(in webapplication1) or targetpage.aspx(in webapplication2) i need to add code for bitmap and drawing bitmap. I am not experienced in asp.net. so i need bit more clarity...

I need to know how for both pages

Thanks for your help but it would be great if you explore it more as a novice one.

Sorry I missed few lines, but still have same prob. It create just boundry not load image and it is also on same page..


ASCIIEncoding encoding = new ASCIIEncoding();
string postImg = folder + Fname;
byte[] data = encoding.GetBytes(postImg);
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://localhost:51399/TestReceive.aspx");
myRequest.Method = "POST";
//myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentType = "multipart/form-data";
myRequest.KeepAlive = true;
myRequest.Credentials = System.Net.CredentialCache.DefaultCredentials;
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();

newStream.Write(data, 0, data.Length);
newStream.Close();

HttpWebResponse response = (HttpWebResponse)myRequest.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
string tmp = reader.ReadToEnd();
response.Close();
Response.Write(tmp);

I write code to post Image on source page as below...I am not sure about it.. If it is correct code then how to receive image on target page ???? Here folder contains the path of the file in which it lies and Fname is name of the image file.

ASCIIEncoding encoding = new ASCIIEncoding();
string postImg = folder + Fname;
byte[] data = encoding.GetBytes(postImg);
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://localhost:51399/TestReceive.aspx");
myRequest.Method = "POST";
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.ContentLength = data.Length;
Stream newStream = myRequest.GetRequestStream();

newStream.Write(data, 0, data.Length);
newStream.Close();

Thanks for your reply..

I have resized the image but i dont know how to post it now.. and how i will receive it on target page.... so could you provide coding for both pages.... post page and receiving page as well...

Please help me..
