Declaring a constant or variable in a windows form

Hi guys!

I'm using the c++ windows forms desinger (VS 2008 Express) for the first time.
If I want to declare a new variable constant or array, one of these or both errors appear:

error C3845: 'CalculatoR::Form1::i': only static data members can be initialized inside a ref class or value type
error C4368: cannot define 'i' as a member of managed 'CalculatoR::Form1': mixed types are not supported

I think that I maybe declare the variable at the wrong position. Where do I have to declare variables ond so on?

Thanks for your help.

Deploying an application with Private assemblies

Hi,
I am using VC++ 2005 with SP1 to develop my application. I want to deploy it on a target machine by using Private side by side assemblies. Hence I have created appropriate application manifest file and copied Microsoft C/C++ Runtimes libraries along with their manifest files to the bin folder of my application and ensure that it is in the path. However I am facing an issue due to a 3rd party library used by my application. This library is a dll built by using VC++ 2005 base libraries. When I try to execute my application I get VC++ runtime error.

Installing VC++ 2005 SP1 redistributable libraries does solves the problem but then my application will be using shared side by side assemblies. I would like to deploy with private side by side assemblies.

Can someone please guide me how do I deploy my application successfully on the target machine taking into account such scenarios.

Thanks and Regards.

Are you sending the ninth record to the printer?

iostream file content modification questions

21-Dec-07 20:15

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! Big Grin | :-D

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 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[^]).

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

outFile<<_T("Test international character : ???????,??????")<<_T("\n");<br />
outFile.close();<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

problem about alloc memory in another library and free in the main project

kcynic21-Dec-07 15:01

21-Dec-07 15:01

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.
