Good - I found the solution after some trying and stuff :p (fail, retry, fail again, error, swear, trying, reading, failing again, fixing, waiting, evil laughing, posting the solution on CodeProject) Here is the code I have now:

public ref class Form1 : public System::Windows::Forms::Form
{
public:
System::Threading::Thread ^thd;
private: System::Void autoSave(void) {
Threading::Thread::Sleep(5000);
warningBox("Test? 5000");
runSave();
}
private: System::Void runSave(void) {
thd = gcnew System::Threading::Thread(gcnew System::Threading::ThreadStart(this, &App2::Form1::autoSave));
thd->Start();
}

private: System::Void LoadFiles(void) {
runSave();
//other code
}

Works like a charm! I started the app - and 5 second later I got this message! (warningBox(std::string msg) is a messageBox produced by the Windows::Apps thingy... :p Thnx everyone! Edit: This code keeps restarting the thread. :)

Quite new yes. I had some CLI C++ at university but never worked with Managed stuff... But I did change the first part to Form1 (referencing to public ref class Form1 : public System::Windows::Forms::Form).. Any way you could help me? :p Or do you might have another idea to realize this 'autosave' thing. The code I currently have is 1400 lines long. :p Kind regards,

Thanks for your reply. I currently have this:

public ref class Form1 : public System::Windows::Forms::Form
{
public:
System::Threading::Thread ^thd;
Form1::MyClass() {
thd = gcnew System::Threading::Thread(gcnew ThreadStart(this, &Form1::autoSave));
}

private: System::Void autoSave(void) {
Threading::Thread::Sleep(5000);
warningBox("Test? 5000");
}

private: System::Void LoadFiles(void) {
thd->Start();
}
}

But it doesnt work due the following errors:

1>d:\app2\app2\Form1.h(61) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
1>d:\app2\app2\Form1.h(63) : warning C4183: 'MyClass': missing return type; assumed to be a member function returning 'int'
1>d:\app2\app2\Form1.h(62) : error C2061: syntax error : identifier 'ThreadStart'
1>d:\app2\app2\Form1.h(62) : error C2143: syntax error : missing ';' before ')'
1>d:\app2\app2\Form1.h(62) : error C2143: syntax error : missing ';' before ')'

1>d:\app2\app2\Form1.h(425) : error C3845: 'App2::Form1::thd': only static data members can be initialized inside a ref class or value type
1>d:\app2\app2\Form1.h(428) : error C2143: syntax error : missing ';' before '.'
1>d:\app2\app2\Form1.h(428) : error C2143: syntax error : missing ';' before '.'

But I corrected Threading::Thread.Sleep(5000); to Threading::Thread::Sleep(5000); which resolved those errors. Now Im still left with C3845.

I am building an application where I want to use some kinda autosave function. I found a post about using threads but I cannot find a way to get it working... Currently I have this: LoadFiles() will get run at the beginning of the application. Here should the autosave thread be started...

public: Threading::Thread thd = new Thread(new ThreadStart(autoSave));
private: System::Void LoadFiles(void) {
			Threading::Thread::Start();
		}
private: System::Void autoSave(void) {
			 Threading::Thread.Sleep(5000);
		 }

And getting the following errors:

1>d:\app2\app2\Form1.h(424) : error C3845: 'App2::Form1::thd': only static data members can be initialized inside a ref class or value type
1>d:\app2\app2\Form1.h(58) : error C2512: 'System::Threading::Thread::Thread' : no appropriate default constructor available
1>d:\app2\app2\Form1.h(426) : error C2352: 'System::Threading::Thread::Start' : illegal call of non-static member function
1> c:\windows\microsoft.net\framework\v2.0.50727\mscorlib.dll : see declaration of 'System::Threading::Thread::Start'
1>d:\app2\app2\Form1.h(429) : error C2143: syntax error : missing ';' before '.'
1>d:\app2\app2\Form1.h(429) : error C2143: syntax error : missing ';' before '.'
1>Build log was saved at "file://d:\App2\App2\Release\BuildLog.htm"

Does anyone have any idea how to solve this OR how to make a better thingy? :p Kind regards,

That works tho! :-O Thanks dude!

Plentyyyyyy lol

I got an application. So called Windows Forms Application. I will try Directory::CreateDirectory. Thanks again. ---------- Edit: The IDE (Visual C++ Studio 2008 Express) cannot find Directory::CreateDirectory. I might to include some file I guess... ---------- Re-edit: CreateDirectory("c:\test", NULL); works... Sort of - now I get the following error:

Hi guys, Here I am again... But now with another problem :p SHCreateDirectoryEx(NULL, "c:\\text", NULL); gives me the following error:

1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

I found that _T("..") should work; giving me the following error:

Does anyone have experience with this function. I want to make a (n absolute) folder and the OS where this will be written for is Vista (sorry - I might upgrade to W7 tho). Could someone give me some hints? Kind regards,

Im not really looking to using vectors. Ah well I think I'll do it otherwise then :p Thanks anyhows!

This post can get deleted - I hoped to take the replies with it.

No Im not driving lol. It works! *cheering the hell outta it* Adding text to the TextBox and with a button its sending the data to my vector string which can be read and send to the output :-\ Thank you very very much! I really needed this line! <33 :rose:

How strange - because I copied it directly from your post - since first of all I hate typing and secondly its always better to copy paste :p But it is working now - let me test the output etc. Thanks in advance <3

Is there any other known way to get text out such TextBox into a string? One made by Microsoft themselves? :p

1>d:\stageappvc\terminalapp\terminalapp\Form1.h(7) : fatal error C1083: Cannot open include file: 'Marshal': No such file or directory :p Yeh - I corrected it but copied the wrong stuff I saw... But with A its still not working :( I am using Visual C++ Express Edition. Downloaded the package yesterday :p

I guess I need the second then. Currently I have

std::string str1 = (const char*)(Marshel::StringToHGlobalAnsi(textBox->Text)).ToPointer();

But it gives me the following errors:

1>d:\stageappvc\terminalapp\terminalapp\Form1.h(200) : error C2653: 'Marshel' : is not a class or namespace name
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(200) : error C2228: left of '.ToPointer' must have class/struct/union
1> type is ''unknown-type''
1>d:\stageappvc\terminalapp\terminalapp\Form1.h(200) : error C3861: 'StringToHGlobalAnsi': identifier not found

So I tried to #include , but that didn't work either. How can I use this function? And by the way - thanks for your fast replies :)

I dont see the relation between the first line and the other two. And I need it otherwise. I have a String^ (coming from textBox->Text) and I want to store this in a string (which I have in a vector).

I have: std::vector textCode; private: System::Windows::Forms::RichTextBox^ textBox; private: System::Windows::Forms::TextBox^ invoerVeld; textBox->Text += invoerVeld->Text + "\r\n"; < works fine textCode.push_back(textBox->Text); < no-go textCode.push_back(invoerVeld->Text); 1>d:\stageappvc\terminalapp\terminalapp\Form1.h(194) : error C2664: 'std::vector<_Ty>::push_back' : cannot convert parameter 1 from 'System::String ^' to 'const std::string &' 1>d:\stageappvc\terminalapp\terminalapp\Form1.h(195) : error C2664: 'std::vector<_Ty>::push_back' : cannot convert parameter 1 from 'System::String ^' to 'const std::string &' So I think I cannot just use string in stead of String. Its a native thing of the TextBox and RichTextBox. I guess... Or if Im wrong, correct me :)

Hello people, I am trying to make an application with in- and output. Input by textboxes and output by writing it to a file. I succeeded to get text from a TextBox^ and put it in a RichTextBox^. No problem. I succeeded to use fstream to 'print' data (string) to a file. Now I want to combine these by using a vector. The problem I am facing is that if I do: fout << textBox->Text; that I get the following error:

1< d:\stageappvc\terminalapp\terminalapp\Form1.h(185) : error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'System::String ^' (or there is no acceptable conversion)
1< C:\Program Files\Microsoft Visual Studio 9.0\VC\include\ostream(653): could be 'std::basic_ostream<_Elem,_Traits> &std::operator <<<char,std::char_traits<char>>(std::basic_ostream<_Elem,_Traits> &,const char *)

If I want to write the

textBox->Text

to my vector. I get the following error:

1>d:\stageappvc\terminalapp\terminalapp\Form1.h(194) : error C2664: 'std::vector<_Ty>::push_back' : cannot convert parameter 1 from 'System::String ^' to 'const std::string &'

I tried to find out what this String^ actually is - but I could not find an accurate answer. I also tried:

textBox->Text.toString()

which failed too. Is anyone able to help me with this? I tried to find examples of how to put TextBox data in a string, but I couldn't find anything useful... Kind regards, Mikki Weesenaar
