Well, yes and no. If I statically link some libraries to the application and fiddle with it's settings it works (local & other computers), and on the other hand if I don't do it I get and error when I want to run the exe on a different machine. Someone told me it has to do with CRT dll's and the whole .Net Framework ... and it's a long story ... thanx for asking Naveen

Wow, that would need that you need to know the format of PDF and encode everything yourself. That's a quite a bit extreme. Why don't you simply use an existing library that does the job for you ?
You can find one here[^] for example (I'm sure if you search a little bit, you'll find plenty of).

For that I have used the below code but I am getting errors can anyone please tell me what is wrong in the below code.

OpenFile(hwnd);
break;

ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = hwnd;
ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = "txt";
if(GetOpenFileName(&ofn))
{
HWND hEdit = GetDlgItem(hwnd, IDC_FILE_LIST);
SendDlgItemMessage(hwnd, IDC_FILE_LIST, LB_ADDSTRING, 0, (LPARAM)ofn);
}
}

When Our application is running, we are able to rename the .exe file from C:\Program files. How can we prevent the file or the folder from getting renamed?? Please post your suggestions..
Thanks for your time and help !!!
|
|
|
|

i think this is only possible if your exe is running from some other directory (i.e. not from C:\Program Files\) try running the executable by going to the directory and running it from there and then try renaming it.. As far as i remember i read somewhere that window's paging and filesystem machenism prevents the file to be renamed if its already being used!
|

|
|
|
The exe is not present in C:\Program Files. It is present inside a folder with the application name but it still allows me to rename the exe file.
|
|
|
|
|
When your app launches, try opening itself with a call to OpenFile() and set the permissions very high. This should in effect lock the file preventing other processes from deleting or renaming it. Remember to release the handle when your program terminates.

If I try to rename an application like Yahoo messenger when it is running..It gives me an error message
"ERROR: Unable to rename.It is being used by another person or program.
Close any programs that might be using the file and try again."
How do I do this for my application also??? So that when anyone tries to rename my application exe, when it is running, this error message appears and they are unable to rename the file..
Please post your suggestions.
Thanx!!!

Hi all,
I receive the following error:
Unhandled exception at 0x0045b287 in updCnf32.exe. 0xC0000005: Access violation writing location 0x00666e63.

Did you use your debugger to see where the problem in your code is ? Can you tell us more about where it happens and what are the value of your variables at this point ?
|
|
|
|
|
Thanx for the reply Cedric,
The exception happens right at this point:
As I press any key, for the getch() the exception occurs.
getch();
return 0;
}
Does this help?

I get a feeling that the stack has become corrupted. Check the memory allocations. If you can't find it that way, try to comment out portions of the code until you can pinpoint the location of the source of the error.

O.k I have done what you said and I have located the place where it happens, can you see anything wrong here:
strcat((char*)szDirPath, (const char*)dtStamp);
char lpExistingFileName[BUF_SIZE];
char lpNewFileName[BUF_SIZE];
strcpy((char*)lpExistingFileName, (const char*)updateFName.c_str());
strcpy((char*)lpNewFileName ,(const char*)szDirPath);
if(CopyFile((LPCTSTR)lpExistingFileName,(LPCTSTR)lpNewFileName,FALSE))
printf("File was moved successfully...\n");
else
printf("File move failed....\n");
Many thanx

Got it ...
#define BUF_SIZE 1000
char szDirPath[BUF_SIZE] = "C:\\CNF_Update_Transactions\\";

Yes, you did.
I couldn't verify your code, since you didn't supply the variable declarations.
But anyhow, the problem is fixed, that's the main thing.
And you got a lesson about what happens in case of a stack corruption. Strange things happens...
