Are you sending the ninth record to the printer?

Let's say there is a file which has content like the below for example:
[Configuration.x86]
Memory = FF1040A0
IO = 2FF
Flag = 12,15 With iostream library,
1. how to locate and modify the value in IO section from "2FF" to "A2FF"?
2. how to delete the token "12," in Flag section?
Thanks.

Why do you want to use iostream when GetPrivateProfileString will make your task so much easier?

My target is oem*.inf in C:\Windows\inf. GetPrivateProfileString is for .ini files. It looks like also working for .inf files. I will try it on Monday. Thanks! 
By the way if the target is gereral article content, what would be a better way (efficient) to modify and to delete substrings in the file?
For example (below paragraph), to delete "will", and locate the next word "make" and append an "s" to form "makes".

Indeed it works whatever file extension is (only the file format is important, it must be *.ini compliant)

You're welcome.

You have to:
(1) load the file in a buffer.
(2) make all you search/replace/add operations into the buffer.
(3) write the buffer to the initial file.
Point (2) maybe accomplished with hand-crafted search operations, using a string class (for instance std::string or CString) or a powerful tool like a Regular Expression parser (see for instance http://www.ultrapico.com/Expresso.htm[^]).

// Get a pointer to the button
CButton *pButton;
pButton = reinterpret_cast<CButton
*>(GetDlgItem(IDC_SUBMIT_BTN));
// Find the rectangle around the button
CRect rectSubmitButton;
pButton->GetWindowRect(&rectSubmitButton);
// Get a pointer to the first item of the menu
CMenu *mnuPopupMenu =
mnuPopupSubmit.GetSubMenu(0);
ASSERT(mnuPopupMenu);
// Find out if the user right-clicked the button
// because we are interested only in the button
if( rectSubmitButton.PtInRect(point) ) // Since
the user right-clicked the button, display the context menu
mnuPopupMenu->TrackPopupMenu(TPM_LEFTALIGN |
TPM_RIGHTBUTTON, point.x, point.y, this);
}

When you add your tray icon with Shell_NotifyIcon(), specify
a window handle and a callback message along with the NIF_MESSAGE
flag.
When the window receives that message, check the LPARAM
for WM_CONTEXTMENU. When you receive that message use
TrackPopupMenu to show the menu.

I try to convert my old MFC application that use multibye encoding to UNICODE by using TCHAR programming method.
but there is a code the create a file using ofstream that I dont know how to convert to TCHAR-programming.
I also tried std::wofstream
<br />
<br />
wofstream outFile(_T("outfile.txt"));<br />
outFile<<_T("Test international character : ???????,??????")<<_T("\n");<br />
outFile.close();<br />
<br />
But it didn't work , only the english portion is written to the output file (and the file are still ASCII as open in notepad).
Can someone suggest me how to fix the problem ?
Edit : those ?????? are suppose to be thai & arabic text

I have a program using another dll library of mine.There are some codes like this:
//caller
std::string* paths = NULL;
int count = find_path_strings(&paths);
if(count>0)
delete [] paths;//error occurs here,the error message tells me that the heap memory is damaged
//in the library
int find_path_strings(std::string** paths)
{
char** paths_array = NULL;
int count = find_paths(&paths_array);//this function will alloc the paths_array
//also will initilize it and return the array element count
*paths = new std::string[count];
for(int i=0;i < count;++i){
(*paths)[i] = paths_array[i];
free(paths_array[i];
}
if(paths_array)
free(paths_array);
return count;
}
but if I copy the source codes in my library to the main program(caller),it will works well.(I using the library with a .dll and a .lib file.)
Someone would tell me why and how to resolve such strange problem?
Thanks.
GOOD LUCK.

Make sure both the DLL and the EXE projects are using the same
CRT library.
Project properties/C++/Code Generation/Runtime Library
If you'll be passing allocations back and forth across the DLL/EXE
boundary, they both need to use the DLL version of the CRT.

Yes,there is one project using MFC in a static library and the other using MFC in shared DLLL.
I change their setting as the same,every thing works well now.Thank you.
Best wishes.

errors occur now!
The same library,I create a new user project(console,MFC surported).No matter I change their setting as Use MFC in a static library or Use MFC in a shared DLL,the user program will crash at the same position: delete
But the older user project(MFC dialog based) will work well no matter its MFC using setting is the same like the library or not.
How should I fix the error,now?Thank you

The problem here is that your EXE and the DLL are using different heaps: you are trying to free memory in one heap that was allocated in another.
There are two common ways around this problem:
1. Add a “DLL_free” exported function to the DLL which you use in the client to free any memory allocated by the DLL. It simply calls “free” but because the code which does this is in the DLL and not the client the correct heap is used.
2. Build the EXE and the DLL using a DLL version of the CRT.
Option 1 is more flexible and professional.

Thanks for your help.But I have some questions about the two options.
1.I believe the option 1 will work,but I want to know,if I should free a lot of heap blocks with different types,I have to define some DLL_free overides?
2.To option 2,I am sorry that,I do not know how to do it.In another word,how should I set this step by step?
|
|
|
|

I also find that their would be some problems about option 1.
Because if I fixed the delete crash,the following code like:
//in the caller
std::string str_temp = get_a_string(...);
...//do something
str_temp = get_another_string(...);//the same run-time error occur again here
...//do something
//in the library
std::string get_a_string(...)
{
std::string str;
...
str = ...;
return str;
}
function get_another_string return a string,too.
If export a DLL_free can fix the error,how about such error?

I recently transfered settings from my laptop to my new desktop. Doing so the laptop doesn't have a "Number Lock" key; so it eliminated the one on my new desktop. Does anyone know I can change the desktop back. I have no idea what to change.
