[SOLVED]: Not Getting Proper Output From Compiled EXE File
-
Hi OriginalGriff, The code for input and output files is
private static readonly string TemplatesFile =
Path.Combine(Directories.CurrentDirectory, "Reports", "ReportsTemplate.xlsx");
private static readonly string MastersFile =
Path.Combine(Directories.CurrentDirectory, "Reports", "Master.xlsx");
private static FileInfo Template = new FileInfo(TemplatesFile);
private static FileInfo Masters;The folders have suitable permissions. Yes, Debug and Release version are on the same computer, under same user. When I run the EXE file I am not getting any output on both Debug and Release versions, but getting nice excel report when I run it from the IDE. I am getting no errors. But, in the output window of the IDE, I am getting lots of First Chance Exceptions like this:
A first chance exception of type 'System.ObjectDisposedException' occurred in System.Data.SQLite.dll
Even though, I am getting a nice excel report. But not from EXE file. Regards.

I'd recommend that you debug it line by line and check if everything is happening as expected, is line 1 getting the values? how about line 2? 3? and so on. is every object instanced correctly? must of the times something really small is what is causing the problem. When you execute the code inside visual studio, the application runs from the debug/release folder, are you executing it from the same location? or you copied the exe to a different folder? could it be is the paths you're using to read and write are not returning a valid path?
I want to die like my grandfather- asleep, not like the passengers in his car, screaming!
Hi Gonzoox, Thanks for the reply. Yes, I had executed and executing the program from the same folder as it was created by the IDE. Moreover, debugging line by line, I am getting proper watch values on each variables. Even though, I will debug it once more as you said. Thanks.

Hello there, WORK: I am working on a project, in which the output of some methods create a excel sheet. PROBLEM: When I run the project from IDE, the excel file is created properly and with all data from List. But, when its run from the compiled EXE file, I am getting no output in the excel file. Please help.
As others have already said, more info would be needed in order to solve the problem. However, I understand the difficulty since the project works in IDE but not as an executable. So what I suggest is that you add some kind of 'messaging' into the code. It could be writing a log file or something similar or simply just show message boxes. Add these messages to the code and run the exe. This should give you better understanding about the execution. Try to add relevant info into the messages such as working directory or the full paths of the file names etc. With the messages you see more easily what happens and what code is reached and what is not.

Hi Mika, As you said I designed a logfile stream writer and now I got my log file full of these two errors:

Based on this any method can dispose the connection and you would see this as a problem in the next call when the disposed connection is trying to be used. So probably the dispose happens elsewhere. To correct this you would need to do a little bit of a re-design. I've touched this problem in Properly executing database operations[^]. Have a look at the initial version and differences in version 2. I think that clarifies the situation.

Thanks a lot Mika, I found a solution. Actually the object SQLiteconnection was disposing and hence not giving the output while running from EXE, but this exception was not being catching while running from the IDE. I removed all the dispose statements in my project and not its running fine. And thanks a lot for you log file idea, it helped me a lot to detect the error.

Hi Mika, Although I am getting the desired result, I know removing all disposed statements is not a perfect solution. Will you please help me to tell Where actually I should apply dispose statement. Regards.

Glad to be of service :) I would recommend not using shared connection objects but having
usingstatements instead as explained in the article. That would make the code much simple and robust in the long run :)Ok, I will keep that in mind for my future projects.

Start by looking at the input and output files: are you using absolute paths? Relative paths? Are they all looking at the same files? What are the folders like - do they have suitable permissions, if they aren't the same? Are the debug and release versions running on the same computer? Under the same user? What happens if you execute the debug version directly in the same way you did with the release? Do you get any error messages? Are you swallowing any exceptions? You need to get information on exactly what is happening - we can't run your code in isolation! :laugh:
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
