In the title you say "at the time of start the application", and in the content - "at the time of first object creation"; they are not the same...

Keep a static class variable of type bool and check whether it is false in the constructor. If so, the first object is being created (now set it true), otherwise - not the first one.

Hi,

I am trying to execute .Net 2005 executable in Test PC.It's not executing and giving an error message "The application has failed to start because the application configuration is incorrect. re-install the application and fix the problem"

Do we need to install any framework or service packs in Test PC? Please help me.

thanks & regards,

I think so. You should install at least Framework 2.0 redistributable package

We have converted .net 2003 application(developed in vc++.net) to .net 2005. But the exe built in .net 2005 is not executing in .net 2003 environment. It is showing error that "initialization required to execute this application and rebuilding the application will fix problem".

To execute that .net 2005 exe under .net 2003 environment do we need to have any frame work or service packs?

Thanks in Advance

You need to rebuild that application in .net 2003 environment, as error says.

Actually that application is developed in .net 2003 and we are converting that in to .net 2005 framework . Now I am executing the exe in .net 2003 environment that is built from .net 2005. This is giving error that "he application is configuration is incorrect".

Even for a small test application developed in .net 2005 and while executing under .net 2003 in seperate test PC is also giving same error.

may be:
HANDLE hFile = CreateFile("test.txt",GENERIC_WRITE,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL ,NULL);
if(hFile == INVALID_HANDLE_VALUE){
if(GetLastError() == 5 || GetLastError() == 4)
{
//this file is being used
}
}else
{
CloseHandle(hFile);
}

Why use constants? It would be much more readable to use:

if (GetLastError() == ERROR_TOO_MANY_OPEN_FILES || GetLastError() == ERROR_ACCESS_DENIED)

an alternative way i think is to use the OF_SHARE_EXCLUSIVE flag as the third argument for the OpenFile() function.

How to delete a file after user close it

rockryan7-Sep-06 17:39

Hi, Expert,

Now I'm implementing a encrypt software, all file is encrypted in a folder,
But when user wanna excute the file, I need decrypt the file and use CreateFile and WriteFile function copy it to a temp file. Then use ShellExecute let user can excute the file. when user edit and save the temp one, I'll encrypt back to the origin encrypt file.

Now my problem is, After user close the file, I need delete the temp one, because all it's content is not encrypt.

I search long time on internet, Can't use "open exclusive" to check is the file opened, because it can't detect notepad or ultraedit, also can't search the window's title to check have the file name or not, because some program may not show file name on window's title.

I found CreateFile have a param FILE_FLAG_DELETE_ON_CLOSE, but can't figure out how to solve my problem, or can you provide any other solution? Thanks!!

I'm not sure about notepad, but when UltrEdit opens a files it first creates a snapshot, reads the file, then closes the handle. I.e. It makes a copy of the file first and uses this copy for all it's read and write operations. If you are creating encrypted files, it is generally a bad idea to write anything unencrypted back to the HD.
