Uninstall Service Bug

Question

0.00/5 (No votes)

See more:

I am working on service(CATlServiceModule).
This service stores the data in buffer.
1) Application(like notepad, wordpad etx) that is in process or we start 2) The URL (facebook.com, timesofindia.com etc)that is currently open

if the time of application is exceeds the time limit that is given in application than application store "time spanning and details" in buffer in XML format and after every 30 min it create an XML, Zip it and send it to server.

This is what my application is doing. Setup is created by .Net team with WIX.
One bug is found during uninstallation is that when setup uninstall the service.During uninstallation i write the code that create XML for the remaining buffer and zip it.
The setup will take care of sending the zip to server.but setup will get message of uninstall first and it start sending the file.
The files are created after setup send the file so all the folders are not deleted during uninstallation.

Is there any way that i can wait when uninstallation done all the process in my code.

If anyone want to see source code than i will paste here.
Thanks in advance.

Update:

Hi Venkatesh, FYI The issue is resolved now. I don't send the file to server during uninstallation, Just delete the file in my code. Thanks for your support :) - Shilpi Boosar

Solution 1

The Uninstaller would take care of uninstalling the files which are installed.

As you said the zip file is created by you while uninstalling the application which is not the part of installation. So, it will not delete it.

Solution 1:

Add a dummp zip file of the same name along with the installation. Now uninstallation will automatically take care of uninstalling.

Solution 2:

If the main application is .NET application, write a class deriving from Install.Installer (its a abstract class) and write your custom actions.

Add Custom Action in Setup Project.

Solution 3:

You said, you will Zip the file. You also write code to send and delete the file.

Hi Venkatesh,
Thanks for your answer :)
Yes very true but the code is written in setup that send these files to server and delete the files during uninstalltion. Setup will take care of it.
Solution 1:
Not possible the name of zip file is not the same always because n number of zips are created.
Solution 2)Main application is written in win32. IN setup the code during uninstalling the service is written "uninstall" and property is set as wait.(I dont know the property wait here :()
3) Yes that code is written in my code also. I did the same thing but failed when i send logs to server.SendLogToServer is done via service and thats why the code is writtern in server.

One think i do is there is SERVICE_STATUS function that have one value dwWaitHint. I set this value to dwWaitHint = 30000, but now the service is uninstall and the status is on services.msc is started and the service is deleted :). Do you have any other solution ???
again thanks for the reply .

3) Yes that code is written in my code also. I did the same thing but failed when i send logs to server.SendLogToServer is done via service and thats why the code is writtern in server.

As uninstall action will delete the Service, "SendLogToServer" will not work. Instead, write the sending files in Xml Creation itself

This i done before deleting the service but i failed.

Write a small .NET Console app to send email. Install along with the main application. Call it when email is to be sent. Delete the files once it is sent. Put some messages (for testing purpose).

I have a strong feeling, that the delete logic you have written if failing. Try adding some messages in there.

ShilpiP 29-Dec-10 4:56am

You didnt get my point i think. During uninstallation when service uninstall the setup get message first that service is uninstalled and the setup done its next task but the service is creating setups and all. thats why the zip files created by service is not installed.
I am a vc++ developer not .net developer :). The setup is created in .net only. :)

In .NET Setup project, you can custom action most probably an EXE or DLL can be assign to it. I want an application (preferable .NET as it has very close link with Setup projects).

If I am not wrong, You service is the one which "Sends" the email. I am asking you to use the application to do that.

It is always very hard to explain when the conversation continues for a long or people from different technologies. Personally from my experience it is hard to explain VC++ guys :D . No offense

No my service is not sending an email. It creates a soap client using WSDL and call one function that is SaveThrackingLog. i receive the response if file is send than i delete the files but if it is failed to send than i dont delete the file. During uninstallation i receive an unknown error. :)
CServicesT<csoapwinhttpclient> objService;
HRESULT hServRes = objService.SaveTrackingLog(bstrBase64Data,&AggResp);
if(AggResp.ResponseType == Services::Success)
{
DeleteFile(m_vstrZipsToSend.at(i).c_str()); //If Success then Deleting File
}
else
{
if(hServRes == S_OK && AggResp.ResponseType != Services::Success)
{
WriteLog(m_strLogFile,_T("SendLogstoServer(Response recieved by AggResp)"),AggResp.Response);
}
else
{
WriteLog(m_strLogFile,_T("SendLogstoServer"),AggResp.Response);
}

objService.Cleanup();
return;
}
Its like this :)
hahaha yes you are write that it is difficult but i think both are microsoft technologies and the base for both the technology is same, the api and all. So it is not hard to understand the things. Do you have any problem with vc++ guys :)). I dont mind if you have :)

Venkatesh Mookkan 29-Dec-10 6:12am

I do have problem with VC++ guys in my work place. They do the Server piece. I work on the Client piece. Always have problem and it is difficult to make them understand, that their code has the Bug.

Frankly speaking, I don't write/speak VC++. I thought of throwing some ideas how to solve your issue. One thing you can do is, place a debug point in the SOAP and see, if you are getting anything from your service.

ShilpiP 29-Dec-10 6:28am

Its not your problem, its a problem of all IT people because it is hard to find out the problem if it is multiplatform.. Same i am facing now. :) The soap is writtern in .net so i am unable to debug that part. i just get error information instead. Anyways thanks for your support.

Venkatesh Mookkan 29-Dec-10 6:43am

Since SOAP is in .NET, you can get help from the concern developer and debug your request. See, if the SOAP is getting your request in the first place.

Then your question itself wrong. But thanks for the update.

ShilpiP 4-Jan-11 2:12am

Nops my question was the same but i found the another solution to solve it. I create the file and create a zip but instead of sending it to server, i delete the file because if user uninstall the service than the data is not to be send to server is ok. I tell this solution to my senior and he is agree with that.
