A tool is what you make of it. Whether it helps you or not can only be determined by you. Others can offer their perspective but the deciding factor is solely yours. Enjoy!

Are you wanting help with the button-click event, or the updating of an edit box?

The button-click event.
Thanks very much in advance David.

Handle the BN_CLICKED message. If you are using MFC, use ClassWizard (Ctrl+W) to create a ON_BN_CLICKED() handler.

I'using Borland C++ builder 4.0. I've got a button which Ive called btnGenerate an edit box called editA. I want to generate a number in the edit box between 0-9 on the click event of the generate button. Are you familiar with the borland C++ builder. I'm not sure I've heard of the MFC.
Many thanks nicolas.

I've not used a Borland product in over a decade. Sorry.

It's part of Microsoft Visual C++, the main topic of this board.

When you are ready for it, here's the code:
int x = rand() % 10;

Hi all,
I have created a DLL from some C++ code (to call from my C# app).
The DLL creates and writes to a couple of files.
However, it writes them to the folder last used by the C# app.
1. Why? (Less important)
2. How do I specify where to write the file, relative to the DLL file. (More Important)
Thanks in advance for any suggestions/hints.

Hi,
Do you use GetModuleFileName() or GetModuleFileNameEx()?
Sincerely Yours,
RadioShark
|

No, but I am not experienced in C++.
They sound like what I need - so what's the difference.

It appears that neither of these are recognised by the compiler - do I need to include them somehow?

If you are receiving a compiler error, make sure that windows.h is included.

Thanks anyway - have solved it another way (in the C#).

sure -
I just set the working directory before calling the DLL.
Environment.CurrentDirectory = Path.Combine(Application.StartupPath, "Working\\");
where /working/ is the directory I want to create the output files in.
The working directory is set by other functions also.

This post indicated you were getting compiler errors. I don't see the relationship between not having GetModuleFileName() or GetModuleFileNameEx() recognized by the compiler, and setting the working directory before calling a DLL.

Dear All,
I am a new comer of this message board. First let me say hi to you all ^_^
I am working on my project in my school which require me to check if there is any new file exist in a folder by using MFC. Since I am just start learning MFC a few weeks before, I totally have no idea about how I can do so........
Would anyone give me some advice on this in details?
Really thanks a lot!
Yours,
Meteor

Hi,
CFile f;
char* pFileName = "test.dat";
if( !f.Open( pFileName, CFile::modeRead | CFile::shareDenyNone ) )
{
#ifdef _DEBUG
afxDump << "File could not be opened " << "\n";
#endif
}
Sincerely Yours,
RadioShark

Oh....I forget to mention that I have to check it continuously, i.e. when I start the program, I have to be able to check it after clicking "Start" button and it will loop continuously to check.....
Will your method be ok on that also?
^_^
Yours,
Meteor

If that is your requirement, use ReadDirectoryChangesW() and/or FindFirstChangeNotification() instead.
Unless it is done infrequently, polling the OS in a loop is not very efficicent.

Oh.....actually I have looked in this site and read an article about the API you mentioned...but I don't understand it much....especially what I need to use it and how to initialize .....  T_T

fwatch.exe is a good example.
