View 2 RepliesLet me preface this by saying that I'm very much a novice coder. I'm currently working on a small project to practice with Visual Basic and have experienced some issues during my save and load process using text files. I think I can solve the issue by changing the way my text file is initially saved. I want to see if I can sort the items and change the order in which they are written to the text file based of the value in one of the lines.[code]....
View 5 RepliesI tried to write a text written in my textbox to file.(a .txt). I scanned it to see if it contained any illegal characters, the program said that it did not. However, when I went to save it it said that the program performed an illegal operation.
System.Runtime.InteropServices.COMException was unhandled Message: Exception from HRESULT: 0x800A0005 (CTL_E_ILLEGALFUNCTIONCALL).
It created the text file but did not write the content of the textbox to the file.I can save the text in Microsoft word without a problem. Is there something wrong with the encoding for the textbox and how do I set the encoding for the characters so I can write it to a text file.

JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:

When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.
I am making a program thats writing to a file. Another program is also writing to the file. Its a txt file. My program adds some text to it.When i click a button in my program, i first want it to check if i was the "last" program who wrote to that file. If i was, then it should not write. If i wasn't, then it should write to it.
I don't know a good method for this, but i know 1 method:after the program has written to the file, it gets the size of the file and saves it. Then next time it gonna write, it checks the size of the file and compared to the saved one. If its the same, it was my program that wrote to it last.
